I'm trying to load a 3D model, stored locally on my computer, into Three.js with JSONLoader, and that 3D model is in the same directory as the entire website.
I'm getting the "Cross origin requests are only supported for HTTP." error, but I don't know what's causing it nor how to fix it.
My crystal ball says that you are loading the model using either file:// or C:/, which stays true to the error message as they are not http://
So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp and change the url to http://example.com/path/to/model
Origin is defined in RFC-6454 as
...they have the same
scheme, host, and port. (See Section 4 for full details.)
So even though your file originates from the same host (localhost), but as long as the scheme is different (http / file), they are treated as different origin.
Just to be explicit - Yes, the error is saying you cannot point your browser directly at file://some/path/some.html
Here are some options to quickly spin up a local web server to let your browser render local files
Python 2
If you have Python installed...
Change directory into the folder where your file some.html or file(s) exist using the command cd /path/to/your/folder
Start up a Python web server using the command python -m SimpleHTTPServer
This will start a web server to host your entire directory listing at http://localhost:8000
You can use a custom port python -m SimpleHTTPServer 9000 giving you link: http://localhost:9000
This approach is built in to any Python installation.
Python 3
Do the same steps, but use the following command instead python3 -m http.server
VSCode
If you are using Visual Studio Code you can install the Live Server extension which provides a local web server enviroment.
Node.js
Alternatively, if you demand a more responsive setup and already use nodejs...
Install http-server by typing npm install -g http-server
Change into your working directory, where yoursome.html lives
Start your http server by issuing http-server -c-1
This spins up a Node.js httpd which serves the files in your directory as static files accessible from http://localhost:8080
Ruby
If your preferred language is Ruby ... the Ruby Gods say this works as well:
ruby -run -e httpd . -p 8080
PHP
Of course PHP also has its solution.
php -S localhost:8000
In Chrome you can use this flag:
--allow-file-access-from-files

Ran in to this today.
I wrote some code that looked like this:
app.controller('ctrlr', function($scope, $http){
$http.get('localhost:3000').success(function(data) {
$scope.stuff = data;
});
});
...but it should've looked like this:
app.controller('ctrlr', function($scope, $http){
$http.get('http://localhost:3000').success(function(data) {
$scope.stuff = data;
});
});
The only difference was the lack of http:// in the second snippet of code.
Just wanted to put that out there in case there are others with a similar issue.
Just change the url to http://localhost instead of localhost. If you open the html file from local, you should create a local server to serve that html file, the simplest way is using Web Server for Chrome. That will fix the issue.
I'm going to list 3 different approaches to solve this issue:
Using a very lightweight npm package: Install live-server using npm install -g live-server. Then, go to that directory open the terminal and type live-server and hit enter, page will be served at localhost:8080. BONUS: It also supports hot reloading by default.
Using a lightweight Google Chrome app developed by Google: Install the app, then go to the apps tab in Chrome and open the app. In the app point it to the right folder. Your page will be served!
Modifying Chrome shortcut in windows: Create a Chrome browser's shortcut. Right-click on the icon and open properties. In properties, edit target to "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:/ChromeDevSession" and save. Then using Chrome open the page using ctrl+o. NOTE: Do NOT use this shortcut for regular browsing.
Note: Use http:// like http://localhost:8080 in case you face error.
Use http:// or https:// to create url
error: localhost:8080
solution: http://localhost:8080
In an Android app — for example, to allow JavaScript to have access to assets via file:///android_asset/ — use setAllowFileAccessFromFileURLs(true) on the WebSettings that you get from calling getSettings() on the WebView.
fastest way for me was:
for windows users run your file on Firefox problem solved, or
if you want to use chrome easiest way for me was to install Python 3 then from command prompt run command python -m http.server then go to http://localhost:8000/ then navigate to your files
python -m http.server
Easy solution for whom using VS Code
I've been getting this error for a while. Most of the answers works. But I found a different solution. If you don't want to deal with node.js or any other solution in here and you are working with an HTML file (calling functions from another js file or fetch json api's) try to use Live Server extension.
It allows you to open a live server easily. And because of it creates localhost server, the problem is resolving. You can simply start the localhost by open a HTML file and right-click on the editor and click on Open with Live Server.
It basically load the files using http://localhost/index.html instead of using file://....
EDIT
It is not necessary to have a .html file. You can start the Live Server with shortcuts.
Hit (alt+L, alt+O) to Open the Server and (alt+L, alt+C) to Stop the server. [On MAC, cmd+L, cmd+O and cmd+L, cmd+C]
Hope it will help someone :)
If you use old version of Mozilla Firefox (pre-2019), it will work as expected without any issues;
P.S. Surprisingly, old versions of Internet Explorer & Edge work absolutely fine too.
For those on Windows without Python or Node.js, there is still a lightweight solution: Mongoose.
All you do is drag the executable to wherever the root of the server should be, and run it. An icon will appear in the taskbar and it'll navigate to the server in the default browser.
Also, Z-WAMP is a 100% portable WAMP that runs in a single folder, it's awesome. That's an option if you need a quick PHP and MySQL server. Though it hasn't been updated since 2013. A modern alternative would be Laragon or WinNMP. I haven't tested them, but they are portable and worth mentioning.
Also, if you only want the absolute basics (HTML+JS), here's a tiny PowerShell script that doesn't need anything to be installed or downloaded:
$Srv = New-Object Net.HttpListener;
$Srv.Prefixes.Add("http://localhost:8080/");
$Srv.Start();
Start-Process "http://localhost:8080/index.html";
While($Srv.IsListening) {
$Ctx = $Srv.GetContext();
$Buf = [System.IO.File]::OpenRead((Join-Path $Pwd($Ctx.Request.RawUrl)));
$Ctx.Response.ContentLength64 = $Buf.Length;
$Ctx.Response.Headers.Add("Content-Type", "text/html");
$Buf.CopyTo($Ctx.Response.OutputStream);
$Buf.Close();
$Ctx.Response.Close();
};
This method is very barebones, it cannot show directories or other fancy stuff. But it handles these CORS errors just fine.
Save the script as server.ps1 and run in the root of your project. It will launch index.html in the directory it is placed in.
I suspect it's already mentioned in some of the answers, but I'll slightly modify this to have complete working answer (easier to find and use).
Go to: https://nodejs.org/en/download/. Install nodejs.
Install http-server by running command from command prompt npm install -g http-server.
Change into your working directory, where index.html/yoursome.html resides.
Start your http server by running command http-server -c-1
Open web browser to http://localhost:8080
or http://localhost:8080/yoursome.html - depending on your html filename.
I was getting this exact error when loading an HTML file on the browser that was using a json file from the local directory. In my case, I was able to solve this by creating a simple node server that allowed to server static content. I left the code for this at this other answer.
It simply says that the application should be run on a web server. I had the same problem with chrome, I started tomcat and moved my application there, and it worked.
I suggest you use a mini-server to run these kind of applications on localhost (if you are not using some inbuilt server).
Here's one that is very simple to setup and run:
https://www.npmjs.com/package/tiny-server
Experienced this when I downloaded a page for offline view.
I just had to remove the integrity="*****" and crossorigin="anonymous" attributes from all <link> and <script> tags
If you insist on running the .html file locally and not serving it with a webserver, you can prevent those cross origin requests from happening in the first place by making the problematic resources available inline.
I had this problem when trying to to serve .js files through file://. My solution was to update my build script to replace <script src="..."> tags with <script>...</script>.
Here's a gulp approach for doing that:
1.
run npm install --save-dev to packages gulp, gulp-inline and del.
2.
After creating a gulpfile.js to the root directory, add the following code (just change the file paths for whatever suits you):
let gulp = require('gulp');
let inline = require('gulp-inline');
let del = require('del');
gulp.task('inline', function (done) {
gulp.src('dist/index.html')
.pipe(inline({
base: 'dist/',
disabledTypes: 'css, svg, img'
}))
.pipe(gulp.dest('dist/').on('finish', function(){
done()
}));
});
gulp.task('clean', function (done) {
del(['dist/*.js'])
done()
});
gulp.task('bundle-for-local', gulp.series('inline', 'clean'))
Either run gulp bundle-for-local or update your build script to run it automatically.
You can see the detailed problem and solution for my case here.
For all y'all on MacOS... setup a simple LaunchAgent to enable these glamorous capabilities in your own copy of Chrome...
Save a plist, named whatever (launch.chrome.dev.mode.plist, for example) in ~/Library/LaunchAgents with similar content to...
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>launch.chrome.dev.mode</string>
<key>ProgramArguments</key>
<array>
<string>/Applications/Google Chrome.app/Contents/MacOS/Google Chrome</string>
<string>-allow-file-access-from-files</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
It should launch at startup.. but you can force it to do so at any time with the terminal command
launchctl load -w ~/Library/LaunchAgents/launch.chrome.dev.mode.plist
TADA! 😎 💁🏻 🙊 🙏🏾
Not possible to load static local files(eg:svg) without server. If you have NPM /YARN installed in your machine, you can setup simple http server using "http-server"
npm install http-server -g
http-server [path] [options]
Or open terminal in that project folder and type "hs". It will automaticaly start HTTP live server.
er. I just found some official words "Attempting to load unbuilt, remote AMD modules that use the dojo/text plugin will fail due to cross-origin security restrictions. (Built versions of AMD modules are unaffected because the calls to dojo/text are eliminated by the build system.)" https://dojotoolkit.org/documentation/tutorials/1.10/cdn/
One way it worked loading local files is using them with in the project folder instead of outside your project folder. Create one folder under your project example files similar to the way we create for images and replace the section where using complete local path other than project path and use relative url of file under project folder .
It worked for me
Install local webserver for java e.g Tomcat,for php you can use lamp etc
Drop the json file in the public accessible app server directory
Start the app server,and you should be able to access the file from localhost
For Linux Python users:
import webbrowser
browser = webbrowser.get('google-chrome --allow-file-access-from-files %s')
browser.open(url)
url should be like:
createUserURL = "http://www.localhost:3000/api/angular/users"
instead of:
createUserURL = "localhost:3000/api/angular/users"
Many problem for this, with my problem is missing '/' example:
jquery-1.10.2.js:8720 XMLHttpRequest cannot load http://localhost:xxxProduct/getList_tagLabels/
It's must be: http://localhost:xxx/Product/getList_tagLabels/
I hope this help for who meet this problem.
I have also been able to recreate this error message when using an anchor tag with the following href:
Example a tag
In my case an a tag was being used to get the 'Pointer Cursor' and the event was actually controlled by some jQuery on click event. I removed the href and added a class that applies:
cursor:pointer;
cordova achieve this. I still can not figure out how cordova did. It does not even go through shouldInterceptRequest.
Later I found out that the key to load any file from local is: myWebView.getSettings().setAllowUniversalAccessFromFileURLs(true);
And when you want to access any http resource, the webview will do checking with OPTIONS method, which you can grant the access through WebViewClient.shouldInterceptRequest by return a response, and for the following GET/POST method, you can just return null.
If you are searching for a solution for Firebase Hosting, you can run the

$http.get('http://localhost:3000').success(function(data) {
$scope.stuff = data;
});
});
The only difference was the lack of http:// in the second snippet of code.
Just wanted to put that out there in case there are others with a similar issue.
Just change the url to http://localhost instead of localhost. If you open the html file from local, you should create a local server to serve that html file, the simplest way is using Web Server for Chrome. That will fix the issue.
I'm going to list 3 different approaches to solve this issue:
Using a very lightweight npm package: Install live-server using npm install -g live-server. Then, go to that directory open the terminal and type live-server and hit enter, page will be served at localhost:8080. BONUS: It also supports hot reloading by default.
Using a lightweight Google Chrome app developed by Google: Install the app, then go to the apps tab in Chrome and open the app. In the app point it to the right folder. Your page will be served!
Modifying Chrome shortcut in windows: Create a Chrome browser's shortcut. Right-click on the icon and open properties. In properties, edit target to "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:/ChromeDevSession" and save. Then using Chrome open the page using ctrl+o. NOTE: Do NOT use this shortcut for regular browsing.
Note: Use http:// like http://localhost:8080 in case you face error.
Use http:// or https:// to create url
error: localhost:8080
solution: http://localhost:8080
In an Android app — for example, to allow JavaScript to have access to assets via file:///android_asset/ — use setAllowFileAccessFromFileURLs(true) on the WebSettings that you get from calling getSettings() on the WebView.
fastest way for me was:
for windows users run your file on Firefox problem solved, or
if you want to use chrome easiest way for me was to install Python 3 then from command prompt run command python -m http.server then go to http://localhost:8000/ then navigate to your files
python -m http.server
Easy solution for whom using VS Code
I've been getting this error for a while. Most of the answers works. But I found a different solution. If you don't want to deal with node.js or any other solution in here and you are working with an HTML file (calling functions from another js file or fetch json api's) try to use Live Server extension.
It allows you to open a live server easily. And because of it creates localhost server, the problem is resolving. You can simply start the localhost by open a HTML file and right-click on the editor and click on Open with Live Server.
It basically load the files using http://localhost/index.html instead of using file://....
EDIT
It is not necessary to have a .html file. You can start the Live Server with shortcuts.
Hit (alt+L, alt+O) to Open the Server and (alt+L, alt+C) to Stop the server. [On MAC, cmd+L, cmd+O and cmd+L, cmd+C]
Hope it will help someone :)
If you use old version of Mozilla Firefox (pre-2019), it will work as expected without any issues;
P.S. Surprisingly, old versions of Internet Explorer & Edge work absolutely fine too.
For those on Windows without Python or Node.js, there is still a lightweight solution: Mongoose.
All you do is drag the executable to wherever the root of the server should be, and run it. An icon will appear in the taskbar and it'll navigate to the server in the default browser.
Also, Z-WAMP is a 100% portable WAMP that runs in a single folder, it's awesome. That's an option if you need a quick PHP and MySQL server. Though it hasn't been updated since 2013. A modern alternative would be Laragon or WinNMP. I haven't tested them, but they are portable and worth mentioning.
Also, if you only want the absolute basics (HTML+JS), here's a tiny PowerShell script that doesn't need anything to be installed or downloaded:
$Srv = New-Object Net.HttpListener;
$Srv.Prefixes.Add("http://localhost:8080/");
$Srv.Start();
Start-Process "http://localhost:8080/index.html";
While($Srv.IsListening) {
$Ctx = $Srv.GetContext();
$Buf = [System.IO.File]::OpenRead((Join-Path $Pwd($Ctx.Request.RawUrl)));
$Ctx.Response.ContentLength64 = $Buf.Length;
$Ctx.Response.Headers.Add("Content-Type", "text/html");
$Buf.CopyTo($Ctx.Response.OutputStream);
$Buf.Close();
$Ctx.Response.Close();
};
This method is very barebones, it cannot show directories or other fancy stuff. But it handles these CORS errors just fine.
Save the script as server.ps1 and run in the root of your project. It will launch index.html in the directory it is placed in.
I suspect it's already mentioned in some of the answers, but I'll slightly modify this to have complete working answer (easier to find and use).
Go to: https://nodejs.org/en/download/. Install nodejs.
Install http-server by running command from command prompt npm install -g http-server.
Change into your working directory, where index.html/yoursome.html resides.
Start your http server by running command http-server -c-1
Open web browser to http://localhost:8080
or http://localhost:8080/yoursome.html - depending on your html filename.
I was getting this exact error when loading an HTML file on the browser that was using a json file from the local directory. In my case, I was able to solve this by creating a simple node server that allowed to server static content. I left the code for this at this other answer.
It simply says that the application should be run on a web server. I had the same problem with chrome, I started tomcat and moved my application there, and it worked.
I suggest you use a mini-server to run these kind of applications on localhost (if you are not using some inbuilt server).
Here's one that is very simple to setup and run:
https://www.npmjs.com/package/tiny-server
Experienced this when I downloaded a page for offline view.
I just had to remove the integrity="*****" and crossorigin="anonymous" attributes from all <link> and <script> tags
If you insist on running the .html file locally and not serving it with a webserver, you can prevent those cross origin requests from happening in the first place by making the problematic resources available inline.
I had this problem when trying to to serve .js files through file://. My solution was to update my build script to replace <script src="..."> tags with <script>...</script>.
Here's a gulp approach for doing that:
1.
run npm install --save-dev to packages gulp, gulp-inline and del.
2.
After creating a gulpfile.js to the root directory, add the following code (just change the file paths for whatever suits you):
let gulp = require('gulp');
let inline = require('gulp-inline');
let del = require('del');
gulp.task('inline', function (done) {
gulp.src('dist/index.html')
.pipe(inline({
base: 'dist/',
disabledTypes: 'css, svg, img'
}))
.pipe(gulp.dest('dist/').on('finish', function(){
done()
}));
});
gulp.task('clean', function (done) {
del(['dist/*.js'])
done()
});
gulp.task('bundle-for-local', gulp.series('inline', 'clean'))
Either run gulp bundle-for-local or update your build script to run it automatically.
You can see the detailed problem and solution for my case here.
For all y'all on MacOS... setup a simple LaunchAgent to enable these glamorous capabilities in your own copy of Chrome...
Save a plist, named whatever (launch.chrome.dev.mode.plist, for example) in ~/Library/LaunchAgents with similar content to...

Not possible to load static local files(eg:svg) without server. If you have NPM /YARN installed in your machine, you can setup simple http server using "http-server"
npm install http-server -g
http-server [path] [options]
Or open terminal in that project folder and type "hs". It will automaticaly start HTTP live server.
er. I just found some official words "Attempting to load unbuilt, remote AMD modules that use the dojo/text plugin will fail due to cross-origin security restrictions. (Built versions of AMD modules are unaffected because the calls to dojo/text are eliminated by the build system.)" https://dojotoolkit.org/documentation/tutorials/1.10/cdn/
One way it worked loading local files is using them with in the project folder instead of outside your project folder. Create one folder under your project example files similar to the way we create for images and replace the section where using complete local path other than project path and use relative url of file under project folder .
It worked for me
Install local webserver for java e.g Tomcat,for php you can use lamp etc
Drop the json file in the public accessible app server directory
Start the app server,and you should be able to access the file from localhost
For Linux Python users:
import webbrowser
browser = webbrowser.get('google-chrome --allow-file-access-from-files %s')
browser.open(url)
url should be like:
createUserURL = "http://www.localhost:3000/api/angular/users"
instead of:
createUserURL = "localhost:3000/api/angular/users"
Many problem for this, with my problem is missing '/' example:
jquery-1.10.2.js:8720 XMLHttpRequest cannot load http://localhost:xxxProduct/getList_tagLabels/
It's must be: http://localhost:xxx/Product/getList_tagLabels/
I hope this help for who meet this problem.
I have also been able to recreate this error message when using an anchor tag with the following href:
Example a tag
In my case an a tag was being used to get the 'Pointer Cursor' and the event was actually controlled by some jQuery on click event. I removed the href and added a class that applies:
cursor:pointer;
cordova achieve this. I still can not figure out how cordova did. It does not even go through shouldInterceptRequest.
Later I found out that the key to load any file from local is: myWebView.getSettings().setAllowUniversalAccessFromFileURLs(true);
And when you want to access any http resource, the webview will do checking with OPTIONS method, which you can grant the access through WebViewClient.shouldInterceptRequest by return a response, and for the following GET/POST method, you can just return null.
If you are searching for a solution for Firebase Hosting, you can run the
firebase serve --only hosting command from the Firebase CLI
That's what I came here for, so I thought I'd just leave it here to help like ones.
If your using VS code just trying loading a live server in there. fixed my problem immediately.
I'm trying to load a 3D model, stored locally on my computer, into Three.js with JSONLoader, and that 3D model is in the same directory as the entire website.
I'm getting the "Cross origin requests are only supported for HTTP." error, but I don't know what's causing it nor how to fix it.
My crystal ball says that you are loading the model using either file:// or C:/, which stays true to the error message as they are not http://
So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp and change the url to http://example.com/path/to/model
Origin is defined in RFC-6454 as
...they have the same
scheme, host, and port. (See Section 4 for full details.)
So even though your file originates from the same host (localhost), but as long as the scheme is different (http / file), they are treated as different origin.
Just to be explicit - Yes, the error is saying you cannot point your browser directly at file://some/path/some.html
Here are some options to quickly spin up a local web server to let your browser render local files
Python 2
If you have Python installed...
Change directory into the folder where your file some.html or file(s) exist using the command cd /path/to/your/folder
Start up a Python web server using the command python -m SimpleHTTPServer
This will start a web server to host your entire directory listing at http://localhost:8000
You can use a custom port python -m SimpleHTTPServer 9000 giving you link: http://localhost:9000
This approach is built in to any Python installation.
Python 3
Do the same steps, but use the following command instead python3 -m http.server
VSCode
If you are using Visual Studio Code you can install the Live Server extension which provides a local web server enviroment.
Node.js
Alternatively, if you demand a more responsive setup and already use nodejs...
Install http-server by typing npm install -g http-server
Change into your working directory, where yoursome.html lives
Start your http server by issuing http-server -c-1
This spins up a Node.js httpd which serves the files in your directory as static files accessible from http://localhost:8080
Ruby
If your preferred language is Ruby ... the Ruby Gods say this works as well:
ruby -run -e httpd . -p 8080
PHP
Of course PHP also has its solution.
php -S localhost:8000
In Chrome you can use this flag:
--allow-file-access-from-files

Ran in to this today.

app.controller('ctrlr', function($scope, $http){
$http.get('localhost:3000').success(function(data) {
$scope.stuff = data;

app.controller('ctrlr', function($scope, $http){
$http.get('http://localhost:3000').success(function(data) {

If your using VS code just trying loading a live server in there. fixed my problem immediately.
I'm using this code to make an AJAX request:
$("#userBarSignup").click(function(){
$.get("C:/xampp/htdocs/webname/resources/templates/signup.php",
{/*params*/},
function(response){
$("#signup").html("TEST");
$("#signup").html(response);
},
"html");
But from the Google Chrome JavaScript console I keep receiving this error:
XMLHttpRequest cannot load
file:///C:/xampp/htdocs/webname/resources/templates/signup.php. Cross
origin requests are only supported for HTTP.
The problem is that the signup.php file is hosted on my local web server that's where all the website is run from so it's not cross-domain.
How can I solve this problem?
I've had luck starting chrome with the following switch:
--allow-file-access-from-files
On os x try (re-type the dashes if you copy paste):
open -a 'Google Chrome' --args -allow-file-access-from-files
On other *nix run (not tested)
google-chrome --allow-file-access-from-files
or on windows edit the properties of the chrome shortcut and add the switch, e.g.
C:\ ... \Application\chrome.exe --allow-file-access-from-files
to the end of the "target" path
If you’re working on a little front-end project and want to test it locally, you’d typically open it by pointing your local directory in the web browser, for instance entering file:///home/erick/mysuperproject/index.html in your URL bar. However, if your site is trying to load resources, even if they’re placed in your local directory, you might see warnings like this:
XMLHttpRequest cannot load file:///home/erick/mysuperproject/mylibrary.js. Cross origin requests are only supported for HTTP.
Chrome and other modern browsers have implemented security restrictions for Cross Origin Requests, which means that you cannot load anything through file:/// , you need to use http:// protocol at all times, even locally -due Same Origin policies. Simple as that, you’d need to mount a webserver to run your project there.
This is not the end of the world and there are many solutions out there, including the good old Apache (with VirtualHosts if you’re running several other projects), node.js with express, a Ruby server, etc. or simply modifying your browser settings.
However there’s a simpler and lightweight solution for the lazy ones. You can use Python’s SimpleHTTPServer. It comes already bundled with python so you don’t need to install or configure anything at all!
So cd to your project directory, for instance
1
cd /home/erick/mysuperproject
and then simply use
1
python -m SimpleHTTPServer
And that’s it, you’ll see this message in your terminal
1
Serving HTTP on 0.0.0.0 port 8000 ...
So now you can go back to your browser and visit http://0.0.0.0:8000 with all your directory files served there. You can configure the port and other things, just see the documentation. But this simply trick works for me when I’m in a rush to test a new library or work out a new idea.
EDIT:
In Python 3+, SimpleHTTPServer has been replaced with http.server. So In Python 3.3, for example, the following command is equivalent:
python -m http.server 8000
You need to actually run a webserver, and make the get request to a URI on that server, rather than making the get request to a file; e.g. change the line:
$.get("C:/xampp/htdocs/webname/resources/templates/signup.php",
to read something like:
$.get("http://localhost/resources/templates/signup.php",
and the initial request page needs to be made over http as well.
I was getting the same error while trying to load simply HTML files that used JSON data to populate the page, so I used used node.js and express to solve the problem. If you do not have node installed, you need to install node first.
Install express
npm install express
Create a server.js file in the root folder of your project, in my case one folder above the files I wanted to server
Put something like the following in the server.js file and read about this on the express gihub site:
var express = require('express');
var app = express();
var path = require('path');
// __dirname will use the current path from where you run this file
app.use(express.static(__dirname));
app.use(express.static(path.join(__dirname, '/FOLDERTOHTMLFILESTOSERVER')));
app.listen(8000);
console.log('Listening on port 8000');
After you've saved server.js, you can run the server using:
node server.js
Go to http://localhost:8000/FILENAME and you should see the HTML file you were trying to load
If you have nodejs installed, you can download and install the server using command line:
npm install -g http-server
Change directories to the directory where you want to serve files from:
$ cd ~/projects/angular/current_project
Run the server:
$ http-server
which will produce the message Starting up http-server, serving on:
Available on:
http://your_ip:8080 and
http://127.0.0.1:8080
That allows you to use urls in your browser like
http://your_ip:8080/index.html
It works best this way. Make sure that both files are on the server. When calling the html page, make use of the web address like: http:://localhost/myhtmlfile.html, and not, C::///users/myhtmlfile.html. Make usre as well that the url passed to the json is a web address as denoted below:
$(function(){
$('#typeahead').typeahead({
source: function(query, process){

REM kill all existing instance of chrome

REM directory path where chrome.exe is located
set chromeLocation="C:\Program Files (x86)\Google\Chrome\Application"
cd %chromeLocation%
cd c:
start chrome.exe --allow-file-access-from-files
change chromeLocation path with yours.
save above as .bat file.
drag drop you file on the batch file you created. (chrome does give restore pages
option though so if you have pages open just hit restore and it will work).
You can also start a server without python using php interpreter.
E.g:
cd /your/path/to/website/root
php -S localhost:8000
This can be useful if you want an alternative to npm, as php utility comes preinstalled on some OS' (including Mac).
For all python users:
Simply go to your destination folder in the terminal.
cd projectFoder
then start HTTP server
For Python3+:
python -m http.server 8000
Serving HTTP on :: port 8000 (http://[::]:8000/) ...
go to your link: http://0.0.0.0:8000/
Enjoy :)
