Firefox SDK：重定向到资源被拒绝 [英] Firefox SDK: Redirect to ressource HTML denied

问题描述

我正在尝试使用Addon SDK编写一个Firefox Addon，以根据URL重定向一些网站。我已经创建了一个HTML页面，并把它放在数据目录中。我得到的路径：

  var data = require（sdk / self）。 
 var myWebsite = data.url（myWebsite.html）; 
  

我使用PageMod来给定一个URL数组来启动脚本：

$ p $ pageMod.PageMod（{
include：ArrayOfUrls，
contentScriptFile：./myScript.js，
contentScriptOptions ：{myWebsite：myWebsite}
}）;


在myScript.js中，我正在检查是否满足一些要求，如果是，我尝试重定向我的本地网站：

  window.location.replace（self.options.myWebsite）; 
  

但是我总是在控制台中得到以下错误信息：

 对象
  -  _errorType =错误
  -  message =从脚本被拒绝访问'resource：//myAddon/data/myWebsite.html'
  

如果我手动输入本地网站的路径（resource：// myAddon / ...）它工作的浏览器的地址栏。如果我重定向到另一个网站（例如， http://example.com/ ），它也可以。

所以我想有一个安全设置，所以我需要改变，以使本地重定向可能，但我找不到任何文档或网络上。我希望这里有人可以告诉我我做错了什么。

解决方案

在package.json中，我不得不添加以下行使其工作：

$ $ p $ permissions：{cross-domain-content：[resource：// myAddon / data /]}

I'm trying to write a Firefox Addon with the Addon SDK to redirect some websites based on their URL. I have created a HTML page and put it in the data directory. I get the path with:

var data = require("sdk/self").data;
var myWebsite = data.url("myWebsite.html");

I'm using PageMod to start a script given an array of URLs:

pageMod.PageMod({
    include: ArrayOfUrls,
    contentScriptFile: "./myScript.js",
    contentScriptOptions: {"myWebsite" : myWebsite}
});

In myScript.js I'm checking if some requirements are fulfilled and if so I try to redirect to my local website with:

window.location.replace(self.options.myWebsite);

But I always get the following error message in the console:

Object
- _errorType = Error
- message = Access to 'resource://myAddon/data/myWebsite.html' from script denied

If I enter the path to the local website (resource://myAddon/...) manually in the adress bar of the browser it works. If I redirect to another website (e.g. http://example.com/) it works as well.

So I guess there's a security setting or so I need to change to make the local redirect possible, but I can't find anything in the documentation or on the web. I hope somebody here can tell me what I'm doing wrong.

解决方案

In package.json I had to add the following line to make it work:

"permissions": {"cross-domain-content": ["resource://myAddon/data/"]}
