如何在Chrome扩展中静默取消webRequest [英] How to cancel webRequest silently in chrome extension

问题描述

我在这里重新发布了来自Chromium-extensions google group的问题。

I'm re-posting my question from Chromium-extensions google group here.

在我的扩展中，我想取消一些基于url模式的webRequest。我的问题是，如果我在 onBeforeRequest 事件侦听器中返回 {cancel：true} ，浏览器将重定向到一个页面，告诉我该请求被某个扩展阻止。但我只是想默默取消请求（因为什么也没有发生）。

In my extension, I want to cancel some webRequests based on url pattern. My problem is that, if I return {cancel:true} in the onBeforeRequest event listener, the browser would redirect to a page telling me that the request is blocked by some extension. But I just want to cancel the request silently(as nothing happened).

我也试着返回 {redirectUrl：} onBeforeRequest 事件侦听器中，控制台会记录一个错误，指出不是有效的URL，并且浏览器底部出现一个条，说：等待扩展。要解散该栏，我然后在该网页中运行内容脚本 window.stop（）。这有时会起作用，但并非总是如此。所以我想知道是否有人有更好的解决方案。感谢!!

I have also tried to return {redirectUrl:""} in the onBeforeRequest event listener, the console would log an error saying that "" was not a valid URL, and a bar appeared at the bottom of the browser, saying "Waiting for extension". To dismiss that bar, I then run content script "window.stop()" in that web page. That works sometimes, but not always. So I wonder if someone has any better solution. Thanks!!

推荐答案

您应该使用javascript：url来代替：

You should use "javascript:" url instead :

{
    redirectUrl:"javascript:"
}
