检测已安装的Chrome扩展 [英] Detecting installed chrome extensions

问题描述

我试图检测Chrome扩展，但是我遇到了问题。当我尝试 jQuery.load（）类似于
chrome-extension：//jffbcpkfdlpegbadfomimojhgaaoaeed/icon.png 或其他文件，我得到这个错误：

 拒绝chrome扩展的加载：//jffbcpkfdlpegbadfomimojhgaaoaeed/icon.png 。必须在web_accessible_resources清单键中列出资源，才能通过扩展名外的页面加载资源。 movie.php？id = 3079：1 
无法加载资源：net :: ERR_FAILED 
  

我可以避免web_accessible_resources？我试图将文件名的大小写从icon.png改为ICON.png而没有成功（ like this ）。

这个想法只是为了检测扩展;没有别的。

我想做一些类似于 this 。 解决方案

扩展程序已安装，对于任何给定的扩展程序，您不应该依赖加载Web可访问的资源（对所有扩展不能均匀工作）的攻击，并使用 chrome.management API ，它专门用于此目的。

  chrome.management.get（'keyoftheextensionyouwanttofind'，function（info）{
 if（！info）{console.log（Extension not installed） ;} 
 else if（！info.enabled）{console.log（Extension installed，but disabled）;} 
 else {console.log（Extension installed and active）;} 
}）; 
  

是的，它会触发权限警告。

I'm trying to detect chrome extensions, but I have a problem. When I try to jQuery.load() something like chrome-extension://jffbcpkfdlpegbadfomimojhgaaoaeed/icon.png or some other file, I get this error:

Denying load of chrome-extension://jffbcpkfdlpegbadfomimojhgaaoaeed/icon.png. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension. movie.php?id=3079:1
Failed to load resource: net::ERR_FAILED 

Can I avoid web_accessible_resources? I tried to change the capitalization of the filename from something like icon.png to ICON.png without success (like this).

The idea is ONLY to detect extension; nothing else.

I want to do something like this.

解决方案

If you need to detect that an extension is installed, for any given extension, you should not rely on hacks like loading web-accessible resources (which do not work uniformly for all extensions) and use chrome.management API which is specifically there for this purpose.

chrome.management.get('keyoftheextensionyouwanttofind', function(info){
  if (!info) { console.log("Extension not installed"); }
  else if (!info.enabled) { console.log("Extension installed, but disabled"); }
  else {console.log("Extension installed and active");}
});

Yes, it will trigger a permission warning.
