Question

我正在编写可以记录所有HTTP请求的chrome扩展，就像控制台窗口中的网络选项卡中的请求一样。

清单文件如下

{
    "manifest_version": 2,

    "name": "Youtube Controls",
    "description": "This extension demonstrates a browser action with kittens.",
    "version": "1.0",

    "permissions": [
        "webRequest",
        "webRequestBlocking",
        "<all_urls>"
    ],
    "content_scripts":[{
        "matches": ["https://www.youtube.com/*"],
        "js":["youtube.js"]
    }],
    "background":{
        "scripts": ["wb.js"]
    },
    "browser_action": {
        "default_icon": "youtube.png",
        "default_popup": "popup.html"
    }
}

youtube.js

chrome.extension.onRequest.addListener(function(request, sender, sendResponse){
    chrome.runtime.sendMessage({
        greeting: 'hello'
    });
});

wb.js（后台脚本）

chrome.runtime.onMessage.addListener(function(request, sender, response){
    console.log(request);
    chrome.webRequest.onCompleted.addListener(function(details){
        console.log(details);
    },{
        urls: ["<all_urls>"]
    });
});

如果我删除chrome.webRequest.onCompleted.addLister()我可以看到console.log正在运行，但如果webRequest脚本在那里，它会在控制台中抛出错误。这是错误：

Error in event handler for (unknown): Cannot read property 'error' of undefined
Stack trace: TypeError: Cannot read property 'error' of undefined

有什么问题？如何解决？
