javascript - XMLHttpRequest: "chrome-extension://"前置到 URL 获取错误: net::ERR_FILE_NOT_FOUND

Question

当我使用 jQuery ajax 或 XMLHttpRequest 在 background.js 中发送请求时，出现错误:

background.js:51 GET chrome-extension://kameliefngmopmegikbnifbclhkihkjm/http%3A%2F%2Fhtcjy.com%2Fmobile%2Fshop%2Fm%2Fg%2Fgoods-1.do%3F net::ERR_FILE_NOT_FOUND

为什么要在我的请求网址前添加extension://kameliefngmopmegikbnifbclhkihkjm/？ 对于该错误我该怎么办。

这是我的代码:

background.js

chrome.webRequest.onBeforeRequest.addListener(function(details) {
    chrome.tabs.query({active:true},function(tab){
        var method = "get";//details.method;
        var actualUrl = "http%3A%2F%2Fhtcjy.com%2Fmobile%2Fshop%2Fm%2Fg%2Fgoods-1.do%3F"; //details.url;
        sendCrossOrigin(actualUrl, method, function(responseText){
            console.log(responseText);
        })
    });
}, {urls: ["*://*/mock/requestOnServer.do?*"]}, ["blocking"] );

function sendCrossOrigin(url, type, success){
    var xhr = new XMLHttpRequest();
    xhr.open(type, url, true);
    xhr.onreadystatechange = function() {
        if (xhr.readyState == 4) {
            // innerText does not let the attacker inject HTML elements.
            //documemt.getElementById("resp").innerText = xhr.responseText;
            //var resp = JSON.parse(xhr.responseText);
            success(xhr.responseText);
        }
    }
    xhr.send();
}

Answer 1

我已经解决了。 这是因为我发布的网址类似于 http%3A%2F%2Fhtcjy.com%2Fmobile%2Fshop%2Fm%2Fg%2Fgoods-1.do%3F

但是我写

"permissions": [
    "tabs",
    "*://htcjy.com/*",
    "*://*/*",
    "webRequest",
    "webRequestBlocking"
  ]

它无法匹配url，所以我调用函数decodeURIComponent来转换为urlhttp://htcjy.com/mobile/shop/m/g/goods-1。做什么？

我真是太蠢了
