根据chrome扩展API,如果设置了权限,则应允许使用XMLHttpRequest对象进行跨域调用:

扩展可以与其来源之外的远程服务器通信,只要它首先请求跨源权限即可.

我正在密切关注本教程,但下面的代码给出了一条错误消息:

XMLHttpRequest无法加载http://www.google.com/search?hl=en&q=ajax.原始chrome-extension:// bmehmboknpnjgjbmiaoidkkjfcgiimbo不允许使用Access-Control-Allow-Origin.

我不仅允许google.com的请求,而且要求任何网站但仍然无法通过.有人可以帮忙吗？

我的清单文件:

{
  "name": "The popup",
  "version": "0.1",
  "popup": "popup.html",
  "permissions": [
    "http://*/*",
    "https://*/*",
    "https://www.google.com/*",
    "http://www.google.com/*"
    ],
  "browser_action": {
    "default_icon": "clock-19.png",
    "default_title": "This is title",
    "default_popup": "popup.html"
  }
}

实际的电话:

function sendRequest() {
    document.write("Sending request");
    var req = new XMLHttpRequest();
      req.open("GET", "http://www.google.com/search?hl=en&q=ajax", true);
      req.onreadystatechange = function() {
          if (req.readyState == 4) {
            if (req.status == 200) {
              alert(req.responseText);
              document.write("OK");
            }
          }
        };
      req.send();
}
