chrome.webRequest.onAuthRequired Listener

Question

我试图拦截chrome扩展中的代理授权.在这里给出答案:Chrome扩展程序中的域授权和阅读文档,我的代码如下所示:

chrome.webRequest.onAuthRequired.addListener(
    function(details, callbackFn) {
        console.log("onAuthRequired!", details, callbackFn);
        //callback({
        //    authCredentials: {username: "1", password: "__TestUse"}
        //});
    },
    {urls: ["<all_urls>"]}
);

问题是callbackFn 未定义但应该是一个函数.

任何人都有一些想法为什么callbackFn是未定义的.当我阅读文档时,我正在做对..

Answer 1

代码工作,我只是忘了添加另一个参数['asyncBlocking'].这段代码工作得很好:

chrome.webRequest.onAuthRequired.addListener(
    function(details, callbackFn) {
        console.log("onAuthRequired!", details, callbackFn);
        callbackFn({
            authCredentials: {username: "1", password: "__TestUser"}
        });
    },
    {urls: ["<all_urls>"]},
    ['asyncBlocking']
);
