javascript - 刷新比。重新加载(无法调用未定义的方法 'authorize')GAPI

Question

我有一个简单的 gapi (Google Drive) 应用程序，我想连接到它。发生了一些奇怪的事情。我有演示中的示例。 https://developers.google.com/drive/web/quickstart/quickstart-js

//Nothing happens
<script src="static/javascript/libs/client.js?onload=Drive._handleClientLoad"></script>

//Works on reload but not refresh
// (reload) "successfully authorization"
// (refresh) "Uncaught TypeError: Cannot call method 'authorize' of undefined"
<script src="static/javascript/libs/client.js" onload="Drive._handleClientLoad"></script>

Javascript:

---

var Drive = {

  _CLIENT_ID: '61183508825.apps.googleusercontent.com',
  _SCOPES: 'https://www.googleapis.com/auth/drive.file',
  _rootid: null,
  authorised: false,

  _auth: function() {
    gapi.auth.authorize({
      'client_id': Drive._CLIENT_ID, 'scope': Drive._SCOPES, 'immediate': true
    },Drive._handleAuthResult);
  },

  _handleClientLoad: function() {
    window.setTimeout(Drive._auth, 1);
  },

  _handleAuthResult: function(authResult)  {
    if (authResult && !authResult.error) {
    // Access token has been successfully retrieved, requests can be sent to the API.
      Drive._validAuth();
    } else {
      // No access token could be retrieved, show the button to start the authorization flow.
      Drive._invalidAuth();
    }
  },

  _invalidAuth: function(){
    Drive.authorised = false;
    console.log("invalid authorization");
  },

  _validAuth: function(){
    Drive.authorised = true;
    console.log("successfully authorization");
  },

 }

为什么会这样？

html 应该与您的第一个代码段一致。你需要弄清楚为什么“什么都没有发生”。可能是 Google 库中的某些限制阻止它调用模块。尝试将 Drive._handleClientLoad 替换为全局函数，该函数又会调用您的模块。或许在其中加入一些控制台日志或调试器，以查看正在执行的内容和未执行的内容。
