I am getting the following error:
XMLHttpRequest cannot load file:///C:/Users/richa.agiwal/Desktop/get/rm_Library/templates/template_viewSettings.html. Cross origin requests are only supported for HTTP.
I realize that this question has been answered before, but I still have not found a solution to my problem. I tried running chrome.exe --allow-file-access-from-files from the command prompt, and moved the file to the local file system, but I still get the same error.
I appreciate any suggestions!
If you are doing something like writing HTML and Javascript in a code editor on your personal computer, and testing the output in your browser, you will probably get error messages about Cross Origin Requests. Your browser will render HTML and run Javascript, jQuery, angularJs in your browser without needing a server set up. But many web browsers are programed to watch for cross site attacks, and will block requests. You don't want just anyone being able to read your hard drive from your web browser. You can create a fully functioning web page using Notepad++ that will run Javascript, and frameworks like jQuery and angularJs; and test everything just by using the Notepad++ menu item, RUN, LAUNCH IN FIREFOX. That's a nice, easy way to start creating a web page, but when you start creating anything more than layout, css and simple page navigation, you need a local server set up on your machine.
Here are some options that I use.
Test your web page locally on Firefox, then deploy to your host.
or: Run a local server
Test on Firefox, Deploy to Host
Firefox currently allows Cross Origin Requests from files served from your hard drive
Your web hosting site will allow requests to files in folders as configured by the manifest file
Run a Local Server
Run a server on your computer, like Apache or Python
Python isn't a server, but it will run a simple server
Run a Local Server with Python
Get your IP address:
On Windows: Open up the 'Command Prompt'. All Programs, Accessories, Command Prompt
I always run the Command Prompt as Administrator. Right click the Command Prompt menu item and look for Run As Administrator
Type the command: ipconfig and hit Enter.
Look for: IPv4 Address . . . . . . . . 12.123.123.00
There are websites that will also display your IP address
If you don't have Python, download and install it.
Using the 'Command Prompt' you must go to the folder where the files are that you want to serve as a webpage.
If you need to get back to the C:\ Root directory - type cd/
type cd Drive:\Folder\Folder\etc to get to the folder where your .Html file is (or php, etc)
Check the path. type: path at the command prompt. You must see the path to the folder where python is located. For example, if python is in C:\Python27, then you must see that address in the paths that are listed.
If the path to the Python directory is not in the path, you must set the path. type: help path and hit Enter. You will see help for path.
Type something like: path c:\python27 %path%
%path% keeps all your current paths. You don't want to wipe out all your current paths, just add a new path.
Create the new path FROM the folder where you want to serve the files.
Start the Python Server: Type: python -m SimpleHTTPServer port Where 'port' is the number of the port you want, for example python -m SimpleHTTPServer 1337
If you leave the port empty, it defaults to port 8000
If the Python server starts successfully, you will see a msg.
Run You Web Application Locally
Open a browser
In the address line type: http://your IP address:port
http://xxx.xxx.x.x:1337 or http://xx.xxx.xxx.xx:8000 for the default
If the server is working, you will see a list of your files in the browser
Click the file you want to serve, and it should display.
More advanced solutions
Install a code editor, web server, and other services that are integrated.
You can install Apache, PHP, Python, SQL, Debuggers etc. all separately on your machine, and then spend lots of time trying to figure out how to make them all work together, or look for a solution that combines all those things.
I like using XAMPP with NetBeans IDE. You can also install WAMP which provides a User Interface for managing and integrating Apache and other services.
Simple Solution
If you are working with pure html/js/css files.
Install this small server(link) app in chrome. Open the app and point the file location to your project directory.
Goto the url shown in the app.
Edit: Smarter solution using Gulp
Step 1: To install Gulp. Run following command in your terminal.
npm install gulp-cli -g
npm install gulp -D
Step 2: Inside your project directory create a file named gulpfile.js. Copy the following content inside it.
var gulp = require('gulp');
var bs = require('browser-sync').create();
gulp.task('serve', [], () => {
bs.init({
server: {
baseDir: "./",
},
port: 5000,
reloadOnRestart: true,
browser: "google chrome"
});
gulp.watch('./**/*', ['', bs.reload]);
});
Step 3: Install browser sync gulp plugin. Inside the same directory where gulpfile.js is present, run the following command
npm install browser-sync gulp --save-dev
Step 4: Start the server. Inside the same directory where gulpfile.js is present, run the following command
gulp serve
To add to Alan Wells's elaborate answer here is a quick fix
Run a Local Server
you can serve any folder in your computer with Serve
First, navigate using the command line into the folder you'd like to serve.
Then
npx i -g serve
serve
or if you'd like to test Serve without downloading it
npx serve
and that's it! You can view your files at http://localhost:5000
If you are using vscode, you can easily start a liver server. Click liver server at the bottom of the page, once the server is started, vscode will tell the port the project is running. Do ensure your project folder is the workspace
This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...
If you have Node.Js setup then you can use http-server. Just run npm install http-server -g and you will be able to use it in terminal like http-server C:\location\to\app.

If you use the WebStorm Javascript IDE, you can just open your project from WebStorm in your browser. WebStorm will automatically start a server and you won't get any of these errors anymore, because you are now accessing the files with the allowed/supported protocols (HTTP).
I was facing this error while I deployed my Web API project locally and I was calling API project only with this URL given below:
localhost//myAPIProject
Since the error message says it is not http:// then I changed the URL and put a prefix http as given below and the error was gone.
http://localhost//myAPIProject
Depends on your needs, but there is also a quick way to temporarily check your (dummy) JSON by saving your JSON on http://myjson.com. Copy the api link and paste that into your javascript code. Viola! When you want to deploy the codes, you must not forget to change that url in your codes!
I have an folder say 'mywebapp' on windows machines. This folder has index.html page, js directory with java script files and css directory with css files.
Now when i open this index.html into browser, the browser displays contents pretty well, as if i have deployed this application on server, which is not the case.
Now i wanted to do same on my Linux machine vm, login-ed through putty. I tried using pythons SimpleHTTPServer which gave me same result. But as soon as i exit from putty session, the webpage doesnt display. seems like SimpleHTTPServer server connection is broken once i exit the putty session.
Please help me.
Or any other professional and easy way to get my webpage displayed. Tomcat seems good option but i don't have root permission and don't want hectic deployment process.
I heard about node.js, but i don't have root permission to install node.
Most simplest way i can suggest it to download and copy tar.gz file from location:
https://tomcat.apache.org/download-70.cgi
1 then gunzip and untar this downloaded file.
2 Go to conf/Catelina/localhost folder.
3 create an xml with your application name, e.g. mywebapp.xml
and put following to this file:
<Context path="/mywebapp" reloadable="false" docBase="<root-path of your application folder>"/>
here "root-path of your application folder" will be the root folder of ypur HTML, js and css files.
Then just start this tomcat using /bin/startup.sh command and check on browser using localhost:8080/mywebapp
I'm using Sails.js 0.10.5 on Node 0.10.33 on Ubuntu Trusty. I'd like to execute the node process as a non-root user with the least possible privileges in the production environment. I'm comfortable with the various options for binding to ports below 1024 but I'm more concerned with directory permissions.
Ideally, I'd prefer the node process only have write access to its log files and nothing else. It should only have read access to the directory containing app.js and below.
At the moment I have needed to grant write access to the ./.tmp directory and also to the ./views directory due to the grunt tasks that run at startup. I'd rather perform the grunt tasks at deploy time as a different user instead of at run-time. The sails www command appeared promising but I couldn't get the desired outcome.
Can someone please point me in the right direction for running Sails.js with zero write access to its assets, views, etc?
Use sails www to build static assets
chmod -R 440 all files and directories, so that your user and the webserver (group) can access the files.
Use nginx/apache to host a webserver on port 80/443 and proxy requests to sails (running on its own port or over a unix socket).
Run sails using PM2 to keep it running and have it manage/collect logs.
Sails will lift, but will be unable to write its .tmp directory, which shouldn't even be necessary since all your static files will be routed to the www directory through nginx/apache.
The simplest solution to me seems to be to separate the grunt tasks that need the elevated privileges out into a separate file that you can call with a different user on deploy. Then sails won't need to run anything and can be read only.
EDITED: I use PM2 with apache as proxy ( with mod WS ).
You can use one proxy like apache to route from port 80 to others internal server ports based on host.
With this way you can run multiple apps in same server.
It has a lot of usefull functions like see the logs how varius apps in terminal, restart and log crashed apps, run app as user, app status ... etc .

I am beginner in PHP and I got the Error for Developed My Project ERROR is Like:
This: Forbidden
You don't have permission to access /quiz.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Please give the suggestion for Solve this problem.
From interpreting the error, I believe that the problem doesn't lie in php but rather in the underlying operating system and filesystem. More specifically, file permissions.
If you are running Apache on Linux the webserver will only be able to serve pages that it can read. This has to do with local filesystem permissions.
I'm taking a leap here, but if your server is run by the user www-data then that user needs read permissions to the .php files in order to serve them as web pages. If these files are in a subdirectory, then that subdirectory and the .php files inside must also be accessible by www-data.
First, make sure that quiz.php is readable by the user www-data, as most likely you would have created this file using a different user account (root? yourself?).
The following command sets the owner of the file quiz.php to www-data
chown www-data quiz.php
This command needs to be issued in the directory where quiz.php is located and it needs to be entered with a user account that has sufficient privileges to change a file's attributes. Normally this is the root account, but it could be you if the server's administrator has given you those permissions.
You can read up on the chown command by typing
man chown
on most Linux systems.
I am very new to node and heroku and I suspect this is some kind of simple permission issue etc, but I can't seem to track it down.
I have several pure javascript files in a sub-directory one level beneath my root directory where my web.js file is sitting. I have a line in my web.js file to specify the directory
app.use('/heatcanvas',express.static(__dirname+'/heatcanvas'));
If I run my app locally with Heroku Foreman I get the expected js response when I run the following curl command
curl localhost:5000/heatcanvas/heatcanvas.js
However when I push to Heroku and hit the corresponsing live url in the browser
www.example.com/heatcanvas/heatcanvas.js
I receive the following:
Cannot GET /heatcanvas/heatcanvas.js
If I check Firebug and/or the Heroku logs I see I am actually getting 404 errors for those files even though the pathing should match what is being done locally. It is also worth mentioning that third party javascript is coming over just fine, it is only when the src attribute of the script tag points to my site that there is an issue. What do I need to do to get my scripts to be available?
I recommend you to use process.cwd() value to get specific directory
process.env.PWD = process.cwd()
at the very beginning of your web.js
let you access files easily.
You can do
app.use('/heatcanvas',express.static(process.env.PWD+'/heatcanvas'));
instead of using
__dirname
Warning: Make sure to execute web.js at the root directory of web.js (Heroku web.js are executed that way)
