How do i set up a custom protocol handler in chrome? Something like:
myprotocol://testfile
I would need this to send a request to http://example.com?query=testfile, then send the httpresponse to my extension.
The following method registers an application to a URI Scheme. So, you can use mycustproto: in your HTML code to trigger a local application. It works on a Google Chrome Version 51.0.2704.79 m (64-bit).
I mainly used this method for printing document silently without the print dialog popping up. The result is pretty good and is a seamless solution to integrate the external application with the browser.
HTML code (simple):
Click Me
HTML code (alternative):
<input id="DealerName" />
<button id="PrintBtn"></button>
$('#PrintBtn').on('click', function(event){
event.preventDefault();
window.location.href = 'mycustproto:dealer ' + $('#DealerName').val();
});
URI Scheme will look like this:
You can create the URI Scheme manually in registry, or run the "mycustproto.reg" file (see below).
HKEY_CURRENT_USER\Software\Classes
mycustproto
(Default) = "URL:MyCustProto Protocol"
URL Protocol = ""
DefaultIcon
(Default) = "myprogram.exe,1"
shell
open
command
(Default) = "C:\Program Files\MyProgram\myprogram.exe" "%1"
mycustproto.reg example:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\mycustproto]
"URL Protocol"="\"\""
#="\"URL:MyCustProto Protocol\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\DefaultIcon]
#="\"mycustproto.exe,1\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open\command]
#="\"C:\\Program Files\\MyProgram\\myprogram.exe\" \"%1\""
C# console application - myprogram.exe:
using System;
using System.Collections.Generic;
using System.Text;
namespace myprogram
{
class Program
{
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
}
}
Try to run the program first to make sure the program has been placed in the correct path:
cmd> "C:\Program Files\MyProgram\myprogram.exe" "mycustproto:Hello World"
Click the link on your HTML page:
You will see a warning window popup for the first time.
To reset the external protocol handler setting in Chrome:
If you have ever accepted the custom protocol in Chrome and would like to reset the setting, do this (currently, there is no UI in Chrome to change the setting):
Edit "Local State" this file under this path:
C:\Users\Username\AppData\Local\Google\Chrome\User Data\
or Simply go to:
%USERPROFILE%\AppData\Local\Google\Chrome\User Data\
Then, search for this string: protocol_handler
You will see the custom protocol from there.
Note: Please close your Google Chrome before editing the file. Otherwise, the change you have made will be overwritten by Chrome.
Reference:

Chrome 13 now supports the navigator.registerProtocolHandler API. For example,
navigator.registerProtocolHandler(
'web+custom', 'http://example.com/rph?q=%s', 'My App');
Note that your protocol name has to start with web+, with a few exceptions for common ones (like mailto, etc). For more details, see: http://updates.html5rocks.com/2011/06/Registering-a-custom-protocol-handler
This question is old now, but there's been a recent update to Chrome (at least where packaged apps are concerned)...
http://developer.chrome.com/apps/manifest/url_handlers
and
https://github.com/GoogleChrome/chrome-extensions-samples/blob/e716678b67fd30a5876a552b9665e9f847d6d84b/apps/samples/url-handler/README.md
It allows you to register a handler for a URL (as long as you own it). Sadly no myprotocol:// but at least you can do http://myprotocol.mysite.com and can create a webpage there that points people to the app in the app store.
This is how I did it. Your app would need to install a few reg keys on installation, then in any browser you can just link to foo:\anythingHere.txt and it will open your app and pass it that value.
This is not my code, just something I found on the web when searching the same question. Just change all "foo" in the text below to the protocol name you want and change the path to your exe as well.
(put this in to a text file as save as foo.reg on your desktop, then double click it to install the keys)
-----Below this line goes into the .reg file (NOT including this line)------
REGEDIT4
[HKEY_CLASSES_ROOT\foo]
#="URL:foo Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\foo\shell]
[HKEY_CLASSES_ROOT\foo\shell\open]
[HKEY_CLASSES_ROOT\foo\shell\open\command]
#="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" \"%1\""
Not sure whether this is the right place for my answer, but as I found very few helpful threads and this was one of them, I am posting my solution here.
Problem: I wanted Linux Mint 19.2 Cinnamon to open Evolution when clicking on mailto links in Chromium. Gmail was registered as default handler in chrome://settings/handlers and I could not choose any other handler.
Solution:
Use the xdg-settings in the console
xdg-settings set default-url-scheme-handler mailto org.gnome.Evolution.desktop
Solution was found here https://alt.os.linux.ubuntu.narkive.com/U3Gy7inF/kubuntu-mailto-links-in-chrome-doesn-t-open-evolution and adapted for my case.
I've found the solution by Jun Hsieh and MuffinMan generally works when it comes to clicking links on pages in Chrome or pasting into the URL bar, but it doesn't seem to work in a specific case of passing the string on the command line.
For example, both of the following commands open a blank Chrome window which then does nothing.
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "foo://C:/test.txt"
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --new-window "foo://C:/test.txt"
For comparison, feeding Chrome an http or https URL with either of these commands causes the web page to be opened.
This became apparent because one of our customers reported that clicking links for our product from a PDF being displayed within Adobe Reader fails to invoke our product when Chrome is the default browser. (It works fine with MSIE and Firefox as default, but not when either Chrome or Edge are default.)
I'm guessing that instead of just telling Windows to invoke the URL and letting Windows figure things out, the Adobe product is finding the default browser, which is Chrome in this case, and then passing the URL on the command line.
I'd be interested if anyone knows of Chrome security or other settings which might be relevant here so that Chrome will fully handle a protocol handler, even if it's provided via the command line. I've been looking but so far haven't found anything.
I've been testing this against Chrome 88.0.4324.182.
open
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default
open Preferences then search for excluded_schemes you will find it in 'protocol_handler' delete this excluded scheme(s) to reset chrome to open url with default application
I have implemented a login with facebook method in my website. Originally it works fine, but suddenly this past few days it won't work anymore, even tough I don't change any source code or settings. After some tracing, I found the problem is when I call FB.api /me? it returns this error:
Error Code 1
Error Sub Code 1357045
Message Unknown Error (empty response)
Type Http
Status 0
Does anyone can help me, please ??
FIXED:
Problem solve at this thread Facebook Login JAvascript SDK, Content Securty Policy
Also this error can be because of some extension added to your browsers such as addBlock, Ghostery etc. In my case it was Ghostery.
I'm trying to build a little application that needs to run the url that is generated by the script at this link: http://blogs.aws.amazon.com/security/post/Tx70F69I9G8TYG/How-to-enable-cross-account-access-to-the-AWS-Management-Console
The application is build with Qt4 and Pyqt4. I create a QWebView and want to load the url that is generated at the end of the script in the link inside the webview.
url = QUrl(ConnectionScript.generateURL())
self.webView.load(url)
self.webView.show()
but this code gives me a "HTTP Status 400 - BadRequest" error. I've tried to change the "load" with "setUrl" but there is no change.
The useful code is only this, other lines are just setting up the GUI (and it's doing fine). Any suggestion about how to fix this and what might the problem be? I think it's something very easy to fix but i can't do it right...
Edit1: i forgot to mention that when i open the generated link in a web browser (like chrome or firefox) all goes well and it gives me no such error
Found out that the problem was this line of code:
request_parameters += urllib.quote_plus("https://console.aws.amazon.com/")
The quote_plus encoded : / so the webView load couldn't process the url in the right way.
Just don't use the urllib.quote_plus method and everything will go as expected.
I had my site running fine on the devp. server. After I migrated the app to my production server. Everything worked until I added an extension and enabled it. The site still works but the product view page doesn't show up. Everytime I click on the product view page, this error is appended to my log file...
CRIT (2): Not valid template file:frontend/base/default/template/page/1column.phtml
I have checked the file it is alright, just same as the one working on the development server. I've tried disabling the only plugin (custom menu) that I have and still the problem persists. I've tried increasing memory_limit but it doesn't help either.
Please help, I am stuck in the middle of nothing.
A common cause of this error is the use of symlinks without enabling this in the admin area…
System > configuration > developer > Template Settings
The error gets triggered in app\code\core\Mage\Core\Block\Template.php around line 243 ( see here ) - so if its not an issue with symlinks then this would be a good place to start debugging.
If you are not using xDebug then where the exception gets caught around line 250 you should either log or var_dump the values of:
$includeFilePath
and
$this->_viewDir
Then make sure they both exist (paying attention to the case)
Failing that you might want to look at permissions.
UPDATE core_config_data SET value = '1' WHERE path = 'dev/template/allow_symlink';
or
INSERT INTO core_config_data (scope, scope_id, path, value) VALUES ('default', 0, 'dev/template/allow_symlink', '1');
I currently store text to speech mp3 files as varbinary(max) in the database. what I want to do is play those audio files using the embed tag where the source is ashx file that will recieve the id of the database record and write the byte array.
My ashx file has the following code
byte[] byteArray = ttsMessage.MessageContents;
context.Response.Buffer = true;
context.Response.Clear();
context.Response.ClearContent();
context.Response.ClearHeaders();
context.Response.ContentType = "audio/mpeg";
context.Response.OutputStream.Write(byteArray, 0, byteArray.Length);
context.Response.End();
The call from the aspx page is as follows
Panel5.Controls.Add(new LiteralControl(String.Format("<embed src='/TestArea/PreviewWav.ashx?source={0}' type='audio/mpeg' height='60px' width='144px'/>", ttsMessage.Id.ToString())));
I have gotten this to work with the following
Panel5.Controls.Add(new LiteralControl(String.Format("<audio controls='controls' autoplay='autoplay'><source src='/TestArea/PreviewWav.ashx?source={0}' type='audio/x-wav' /></audio>", ttsMessage.Id.ToString())));
Using the audio tag but cannot seem to get it to work with the embed tag.
I am using IE9/VS2010
Any ideas?
I think the wrong thing with embed tag is that...
Embed tag call a plugin like winmediaplayer ocx than handler firstly called from web page than media plugin get the ashx url than it started to call handler.
But web page's request and mediaplayer plugin's requests are diffent so if you check users Authentication or some other header information it fails.
You can easily see that on fiddler utility. On fiddler top-right side shows the request info. there is a user-agent part. Look it carefully.
How many requests happen from your handler,notice them. What are the differs. for each reqs.
If you have this issue,
You may use a ticket system or redirect a safety area for download without header or other request checks. Sadly web page requst cannot complately transfer media player and others.
hope helps
