在选项卡中查看URL并将其阻止,以便在发送之前不会调用它或更改它

Question

我想通过提供URL地址来阻止要调用的URL,例如:

这不起作用,但这样的事情.

$.watch("http://www.test.com/alter.php",function(){
    //It was called here
    return false; //This in this scenario would block the URL to be called, it would cancel its request, it wouldn't even send the request, it would cancel before it access the web.
});

是否可以阻止URL,以便在通过Google扩展程序在标签中调用之前不会调用或更改其请求？

提前致谢.

您可以在阻止模式下使用chrome.webRequest的onBeforeRequest方法来取消导航.

您的清单需要声明"webRequest"和"webRequestBlocking"的权限.

然后添加一个挂钩onBeforeRequest的后台脚本,并取消该URL的导航:

chrome.extension.onBeforeRequest.addListener(function() { return {cancel: true} },
  { urls: ["http://www.test.com/alter.php"] },
  ["blocking"]
);
