When using browser context in Node-Webkit, is there any way to find out what is the exact User Agent used for external requests, from within Node-Webkit?
Example: if Node-Webkit loads an image that's in an HTML from some remote, I would like to know what's the User Agent this remote will see.
Using a sniffer (Fiddler/Wireshark) is trivial, but I'm looking for a method to obtain this information directly.
Thank you.
Well, given that you can definitely do this:
iframeID.setAttribute('nwUserAgent', 'Super Browser');
Then I can't see why you can't also do this:
Agent = iframeID.getAttribute('nwUserAgent');

FileRun has a beautiful File-Explorer Google-Drive styled. You can testdrive it here FileRunDemoSite
When I download a File I get to choose if I want to open the file directly in a Office Application.
When I click on Office, google prompts me with a Chrome Open File Dialog. The File opens directly from the location instead of being savend in /downloads/ folder.
How can I achieve this behavior? All existing answers on SA state that this is not possible, so this might be interesting to others as well. Not even google has implemented this. Is there a cross-browser solution?
Onedrive does it as well:
Credit to Thomas2D to get me on the right track. How it basically works is:
If you develop an application you can register a new protocol with the operation-system. http:// will be handled by your default browser. applicationX:// will be handled by applicationX, ms-word:// will be handled by word. If you click on a link the browser/operating-system looks up which application should handle the protocol an pass the request on to this application.
For Office documents the URI is a bit more complex ms-excel:ofv|u|http://contoso/Q4/budget.xls. You can open it readonly/ for edit / as a template. Check out this document for a detailed description of all the options: Office URI Schemes
For other applications check the URI Schemes with that application.
How to use it on a website:
It is not advisable to set a link to an application in a Dom element href attribute. You have no way of checking if the application is installed or not.
If you use Javascript you can check if the request times out / fails and use http:// instead.
. Set the protocol in a href: window.location.href = encodeURI('ms-excel:ofe|u|http://example.com/excel.xlsx') or by setting the the location.protocol, https://www.w3schools.com/jsref/prop_loc_protocol.asp
There is a jQuery Plugin to do that :jquery.applink.js
I personally think that this is accomplished by starting application via specific url.
I know that this works on iOS for launching application. In iOS it was done by something (simillar to mailto:example#example.com)
<script type="text/javascript" charset="utf-8">
window.location = "myapplication://myparams";
</script>
EDIT: I finally get it, you have to use application url scheme. For example, if you want to open your Excel file via browser, you have to use this JS code.
window.location.href = encodeURI('ms-excel:ofe|u|http://example.com/excel.xlsx');
I have apache installed on a windows laptop that is not connected to the internet. The laptop has multiple user accounts. Let's say that two of the user accounts are "Adam" and "Sally". I have a project on localhost that needs to differentiate between the different Window's users via the Chrome browser.
I understand detecting the username through the browser directly is a gross security sandbox breach, but I don't care: I have complete control of the computer and the project is not web accessible, so there are no security concerns. I'm willing to cheat in any way imaginable including building a custom .exe to help. I just need to differentiate between the different accounts. It doesn't need to be by username, but any alternative ID would need to persist for that given user.
I am asking for outside of the box thinking.
How can I create a page that I can open in Chrome that will say "Hi Adam" or "Hi Sally" or even "Hi -=[GUID]=-" without the visitor ever typing in their name/guid.
You should probably use something like NW.js or Electron instead of chrome for this so you don't have to sacrifice security.
Here's a picture of me running the nw.js sdk and loading just the demo page, bringing up the dev tools and retrieving my username.
Pretty straight forward. Follow node documentation and do whatever you'd like there.
You could have a batch file that runs on startup via the task scheduler or registry in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run or Local Group Policy that performs something like echo setCurrentUser("%USERNAME%"); > c:\your_project_directory\set-current-user.js, then you just have a script that defines <script>function setCurrentUser(s) { alert("Hello "+s); /* ... */ }</script> followed by a script import like <script src="set-current-user.js"></script>
If you just want to be able to do whatever in the filesystem, change the shortcut that launches Chrome to --allow-file-access-from-files --user-data-dir=c:\your_project_directory --disable-web-security and restart the PC (or just kill all chrome.exe processes, incl. background).
Edit: Updated with note on using --allow-file-access-from-files from Pritam Banerjee. If you go that route, he gets credit. :)
If you're interested in trying NW.js, here's a full example:
package.json :
{
"name": "nw-hello-user",
"version": "0.0.1",
"main": "index.html"
}
index.html :
<!DOCTYPE html>
<html>
<head>
<title>Hello!</title>
</head>
<body>
Hello <script>document.write(process.env.USERNAME)</script>!
</body>
</html>
Here's the command line:
Here's the end product!
Since you tagged your question with PHP, you could just create a index.php file with the following contents:
Hi <?= getenv("USERNAME") ?>
getenv("USERNAME") returns the the value of the USERNAME environment variable.
Update: Thanks to TylerY86 for providing the more correct way to get the username. Also note from his comment below:
You also have to be sure that the Apache instance is running in the
context of the user, and not as a service. If you try the example, if
you get something like SYSTEM or IUSR_MACHINE instead of the user
name, you'll need to adjust.
You have 2 choices, as far as I see.
1) you may ask users to identify themself first time they use the page and store it to the local storage. Since those are different users on the machine, their localStorages should be separate.
2) You may deploy a small web service on the local host, that gets the user credentials from the system and returns on GET request.
This applies both to Android and iOS. My web page may be sometimes opened by an app (you go to the app, and click a link there which opens the page).
I want to know if the page was accessed through an app or if the user got to it, let's say, by typing the address on the browser.
If accessed through an app, I don't need to know which app it was.
The only thing I know of is document.referrer, but it seems to return "" when the page has been opened by the app. Unfortunately using "" as an indicator is not possible, as other ways of getting to the page may also show "" (for example typing the address). The history object does not seem to contain the info I'm looking for either.
I am using a Zendesk Help Center, so I only have access to the javascript of the page in order to detect this. I can't make changes on the server-side of my page.
Alternatively, I may be able to talk to the people in charge of the app so that they include something when the app opens the browser which would allow me to access that info on the browser, but I am not sure what that could be. Any ideas?
Thank you!
It seems to me like your best bet would be to have specific links for your site that will let you know that the link came from the app.
Like so: http://www.yoursite.com/?openedFromApp
You will use those links inside the app that will be directing users to your website.
That way, if you were using PHP as your server-side language you'd be able to check if the openedFromApp URL parameter was set like so:
<?php
if(isset($_GET['openedFromApp'])) {
echo "The website was opened by an app";
}
else { echo "The website was opened normally"; }
?>
If you want to check if the openedFromApp URL parameter is set using Javascript you'd have to create your own function for accessing URL parameters as Javascript does not have a built-in way of accessing them.
But this link could help you access the URL parameters with Javascript: https://stackoverflow.com/questions/...
I am developing a website.
What does mailto: open in if there is no email client (like Outlook, Thunderbird, etc.)?
It works on my computer, which has Outlook, but what if one wants mailto: to open in, say, gmail.com?
What do I need to put in the mailto: statement for that to happen?
As a web developer you don't have any control over the software that a user chooses to open their email, since it's handled by that user's web browser settings, or the OS. If a user has no email program installed on their machine and no operation defined for "mailto" links in their browser, nothing would happen.
The following solution works for me:
(function($)) {
$('a[href^=mailto]').each(function() {
var href = $(this).attr('href');
$(this).click(function() {
var t;
var self = $(this);
$(window).blur(function() {
// The browser apparently responded, so stop the timeout.
clearTimeout(t);
});
t = setTimeout(function() {
// The browser did not respond after 500ms, so open an alternative URL.
document.location.href = '...';
}, 500);
});
});
})(jQuery);
For more info see: https://www.uncinc.nl/articles/dealing-with-mailto-links-if-no-mail-client-is-available
I believe you can use this. https://mail.google.com/mail/?view=cm&fs=1&to=email#domain.com
This however does have its flaws in which the user must be already signed into gmail. Hope this helps!
What happens is entirely up to the client. The OS defines protocol handlers for protocols like mailto: or tel:, etc.
You would need access to the client's registry (in case of a Windows system) to manipulate the handling application for your protocol handler.
For Outlook 2013 as the designated handler, the according Registry structure looks like this:
[HKEY_CLASSES_ROOT\mailto]
#="URL:mailto"
"EditFlags"=hex:02,00,00,00
"URL Protocol"=""
[HKEY_CLASSES_ROOT\mailto\DefaultIcon]
#="C:\\PROGRA~2\\MICROS~1\\Office15\\OUTLOOK.EXE,-9403"
[HKEY_CLASSES_ROOT\mailto\shell]
#="open"
[HKEY_CLASSES_ROOT\mailto\shell\open]
[HKEY_CLASSES_ROOT\mailto\shell\open\command]
#="\"C:\\PROGRA~2\\MICROS~1\\Office15\\OUTLOOK.EXE\" -c IPM.Note /mailto \"%1\""
with a corresponding structure under HKCU.
The mailto URI scheme doesn't decide what happens-- it simply instructs the browser you're using to do whatever it's been configured to do to send e-mails (see the IETF proposed standard for more info). Therefore, you'll have to consult the browser itself to see what it does if no e-mail client is configured.
According to the documentation and to my personal experience, I don't see any way of manually setting an action: It might be possible with certain browsers with some non-standard syntax, but this is unlikely since this would open up a huge potential security problem by being able to execute an arbitrary command by click (such as downloading a virus or something like that).
I found an nice script while searching and inspecting the elements of some websites.
This is what I have found:
<script type="text/javascript">
//redirect browser to fullscreen preview
if (/^http:\/\/codecanyon\.net/.test(document.referrer))
window.top.location.href = 'http://www.gravitysign.com/backslider/';
</script>
So if I understood from this script it tells jquery if the website is opened over codecanyon redirect them to specifed website for preview.
Now... I was wondering if there is possibility to make something like this.
If we specify an website for example http://google.com and we input that into javascript... And then if that website is uploaded to any other domain, other then google.com ... It will redirect to specified site (google) ?
So to clear things out a little bit let me make an example.
If I made a website for "an-website.com" and then someone take their website and upload it to "another-website.com", it will automatically redirect all visitors from another-website.com to an-website.com.
Hope I was clear enough and hope that this is possible. Cheers!
You can of course redirect any user accessing your site from a domain not matching yours but using javascript. This should work just fine:
if (window.location.hostname !== 'yourdomain.com'){
window.top.location.href = 'http://yourdomain.com';
}
You can also use match, if you host your site on a subdomain, etc.
Keep in mind that any person with write access to the file on the server will be able to remove this "copy protection". Copy protecting client side content is impossible, as you need to serve the content in a way a browser understands, effectively making the content available to anyone.
If you are looking for solution for single domain protection, here you can see my
