【问题描述】：

我在虚拟主机（以及 Python SimpleHTTPServer）上运行，我一直按照 Google 的说明进行操作，但我无法在页面刷新时弹出 Google 驱动器授权。

https://developers.google.com/drive/web/auth/web-client

我将第一个代码块放在我的index.html 文件中，并将以下 2 个 sn-ps 放在 <script> 标记中 <body> 中。我用我在 Google 开发者控制台中创建的 ID 填写了 CLIENT_ID...我错过了什么？

 <html>
      <head>
        <script type="text/javascript">
          var CLIENT_ID = '1052173400541-355uhjrflurk7fmlon0r5umnn12i9ag3.apps.googleusercontent.com';
          var SCOPES = [
              'https://www.googleapis.com/auth/drive.file',
              'email',
              'profile',
              // Add other scopes needed by your application.
            ];

          /**
           * Called when the client library is loaded.
           */
          function handleClientLoad() {
            checkAuth();
          }

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

          /**
           * Called when authorization server replies.
           *
           * @param {Object} authResult Authorization result.
           */
          function handleAuthResult(authResult) {
            if (authResult) {
              // Access token has been successfully retrieved, requests can be sent to the API
            } else {
              // No access token could be retrieved, force the authorization flow.
              gapi.auth.authorize(
                  {'client_id': CLIENT_ID, 'scope': SCOPES, 'immediate': false},
                  handleAuthResult);
            }
          }
        </script>
        <script type="text/javascript" src="https://apis.google.com/js/client.js?onload=handleClientLoad"></script>

            function loadClient(callback) {

【解决方案1】：

通过设置immediate=true，您正在抑制身份验证弹出窗口。

第一次应该是false，之后每小时刷新一次通常设置为true。
