Question

我已经从教程https://developers.google.com/+/web/signin/设置了我的简单Google登录按钮，我想知道如何执行以下操作：

限制电子邮件字段中的所有域名，但@ domain.com除外所以johndoe@gmail.com将无效，但johndoe@twitter.com将被接受。有道理吗？
如果用户已登录Google帐户，是否可以“强制”用户再次登录？

这是我的Javascript / jQuery代码：

<script type="text/javascript">

      (function() {
       var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
       po.src = 'https://apis.google.com/js/client:plusone.js';
       var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
     })();


  function signinCallback(authResult) {
  if (authResult['access_token']) {
    // Successfully authorized
    // Hide the sign-in button now that the user is authorized, for example:
    document.getElementById('signinButton').setAttribute('style', 'display: none');

    $('.inline-field-title').hide();


  } else if (authResult['error']) {
    // There was an error.
    // Possible error codes:
    //   "access_denied" - User denied access to your app
    //   "immediate_failed" - Could not automatically log in the user
    // console.log('There was an error: ' + authResult['error']);
  }
}


  function disconnectUser(access_token) {
  var revokeUrl = 'https://accounts.google.com/o/oauth2/revoke?token=' +
      access_token;

  // Perform an asynchronous GET request.
  $.ajax({
    type: 'GET',
    url: revokeUrl,
    async: false,
    contentType: "application/json",
    dataType: 'jsonp',
    success: function(nullResponse) {
      // Do something now that user is disconnected
      // The response is always undefined.
    },
    error: function(e) {
      // Handle the error
      // console.log(e);
      // You could point users to manually disconnect if unsuccessful
      // https://plus.google.com/apps
    }
  });

}
// Could trigger the disconnect on a button click

$('#revokeButton').click(disconnectUser);


</script>

广告1）您必须在手动登录后查看电子邮件，并在电子邮件与您要查找的任何域名不匹配时采取相应措施。

要执行此操作，您必须请求一个额外的范围https://www.googleapis.com/auth/userinfo.email，您可以在登录按钮标记的data-scope参数中定义该范围，并在身份验证后对{{1}执行经过身份验证的请求这将返回响应中的电子邮件地址。

有关示例代码，请参阅https://developers.google.com/+/web/people/#retrieve_an_authenticated_users_email_address。

广告2）登录按钮接受参数https://www.googleapis.com/oauth2/v2/userinfo，该参数将在每次登录尝试时显示身份验证对话框（并让用户切换到其他帐户）。
