在Chrome扩展程序中读取和修改HTTP GET请求 [英] Reading and modifying the HTTP GET request in a Chrome extension

问题描述

我想在Chrome扩展程序中读取和修改(添加)HTTP标头.我使用的是chrome.webRequest API.但是我仍然无法阅读它.这是我的代码.

I would like to read and modify (add) HTTP headers in a Chrome extension. I am using the chrome.webRequest API for the same. But i am still not able to read it. Here's my code.

chrome.webRequest.onBeforeSendHeaders.addListener(

    function(details) {
    details.requestHeaders.push({name:"dummyHeader",value:"1"});
    return {requestHeaders: details.requestHeaders};
    },

    {urls: ["<all_urls>"]},
    ["requestHeaders"]

);

我想念什么?

推荐答案

您需要将"blocking"标志添加到ExtraInfoSpec列表中，以暂停请求.没有此标志，将忽略onBeforeSendHeaders事件侦听器的返回值.

You need to add the "blocking" flag to the ExtraInfoSpec list in order to pause the request. Without this flag, the return value of an onBeforeSendHeaders event listener is ignored.

chrome.webRequest.onBeforeSendHeaders.addListener(
    function(details) {
        details.requestHeaders.push({name:"dummyHeader",value:"1"});
        return {requestHeaders: details.requestHeaders};
    },
    {urls: ["<all_urls>"]},
    ["requestHeaders", "blocking"]
                      //^^^^^^^^
);

我建议您仔细阅读文档，尤其是注册事件监听器部分.

I suggest to read the documentation more carefully, in particular the Registering event listeners section.
