问题与验证用户使用JavaScript和GMail API

Question

我正在学习JavaScript和API的，我正在练习与Gmail。我使用JavaScript网页验证Gmail。

我得到它的工作，但我试图控制台登录用户的电子邮件后，他们进行身份验证。我尝试了许多没有成功的东西

当用户单击按钮handleAuthClick(event)打开一个iframe并开始auth过程。

我怎样才能console.log的电子邮件地址？

<script type="text/javascript"> 
    var CLIENT_ID = '123.apps.googleusercontent.com'; 
    var SCOPES = ['https://mail.google.com/'];

    * Check if current user has authorized this application. 
    */ 
    function checkAuth() { 
    gapi.auth.authorize(
     { 
     'client_id': CLIENT_ID, 
     'scope': SCOPES.join(' '), 
     'immediate': true 
     }, handleAuthResult); 
    } 

function listMessages(userId, query, callback) { 
    var getPageOfMessages = function(request, result) { 
    request.execute(function(resp) { 
     result = result.concat(resp.messages); 
     var nextPageToken = resp.nextPageToken; 
     if (nextPageToken) { 
     request = gapi.client.gmail.users.messages.list({ 
      'userId': userId,

我真的不明白你在哪里尝试控制电子邮件地址？在authorize后它去回调函数“handleAuthResult”，那么你加载函数“loadGmailApi” gmail的API，并在此行之后：

gapi.client.load('gmail', 'v1', listLabels); 

你可以问你想要gapi.client方法什么都来自here以及特定于邮箱地址gapi.auth2.BasicProfile
