Chrome扩展程序gmailAPIcookiePolicy？

我正在构建一个chrome扩展程序,它将读取用户的电子邮件并检查它们是否存在拼写错误.但是,当我尝试在我的background.js中验证用户时,我遇到了这个错误:

uO {message:"无效的COOKIEPolicy",堆栈:"gapi.auth2.ExternallyVisibleError:无效的COOKIEP ...在handleResponse(extensions :: sendRequest:67:7)"}

这是我试图验证它们的方式:

background.js

var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/Javascript';
script.src = "https://apis.google.com/js/client.js?Onload=callbackFunction";
head.appendChild(script);

chrome.identity.getAuthToken({interactive: true}, authorize);

function authorize(token) {
    gapi.auth.authorize({
        client_id: '800382879116-k3luktdc1lmb1e1fml8i8u.apps.googleusercontent.com',
        immediate: true,
        scope: 'https://www.googleapis.com/auth/gmail.readonly'
    },
    function(result){
        console.log(result);
        gapi.client.load('gmail', 'v1', callback);
    });
}

background.html

的manifest.json

    "version": "0.1",

      ]
    },

    },
    "background": {
      "page": "background.html",
      "persistent": false
    },

      "32": "images/Icon_32.png",

      "128": "images/Icon_128.png"
    },

    "key": "c0Kn5f+t92r4P8lmmoDlKtQ6X9Q42UfFtkkiSRBAVMPHnIHqOQvYC67VczJefSNTGpUYa8+wQDFoFj/clH9SfR+BvOGgI6BUVKBNGGoFS"
  }

我现在非常失落,因为他们似乎并不是实现我在任何地方所做的事情的明确指南.有谁知道我可能做错了什么？
