我正在使用 Java Script Google Drive API，并且能够通过 API 成功获取我的 google drive 内容。

现在假设我在某些文件夹中有某些文件，并且在其他用户登录我的应用程序时，他们可以访问我驱动器中的这些文件。使用当前的 Google Drive API 是否可能，用户可以登录到我的 APP 并访问我在我的 Google Drive 中的文件。

这是从谷歌驱动器获取文件的代码：

<!DOCTYPE html>
<html>
  <head>
    <title>Drive API Quickstart</title>
    <meta charset='utf-8' />
  </head>
  <body>
    <p>Drive API Quickstart</p>

    <!--Add buttons to initiate auth sequence and sign out-->
    <button id="authorize-button" style="display: none;">Authorize</button>
    <button id="signout-button" style="display: none;">Sign Out</button>

    <pre id="content"></pre>

    <script type="text/javascript">
      // Client ID and API key from the Developer Console
      var CLIENT_ID = 'CLIENT_ID_GOES_HERE';

      // Array of API discovery doc URLs for APIs used by the quickstart
      var DISCOVERY_DOCS = ["https://www.googleapis.com/discovery/v1/apis/drive/v3/rest"];

      // Authorization scopes required by the API; multiple scopes can be
      // included, separated by spaces.
      var SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly';

      var authorizeButton = document.getElementById('authorize-button');
      var signoutButton = document.getElementById('signout-button');

      /**
       *  On load, called to load the auth2 library and API client library.
       */
      function handleClientLoad() {
        gapi.load('client:auth2', initClient);
      }

      /**
       *  Initializes the API client library and sets up sign-in state
       *  listeners.
       */
      function initClient() {
        gapi.client.init({
          discoveryDocs: DISCOVERY_DOCS,
          clientId: CLIENT_ID,
          scope: SCOPES
        }).then(function () {
          // Listen for sign-in state changes.
          gapi.auth2.getAuthInstance().isSignedIn.listen(updateSigninStatus);

          // Handle the initial sign-in state.
          updateSigninStatus(gapi.auth2.getAuthInstance().isSignedIn.get());
          authorizeButton.onclick = handleAuthClick;
          signoutButton.onclick = handleSignoutClick;
        });
      }

      /**
       *  Called when the signed in status changes, to update the UI
       *  appropriately. After a sign-in, the API is called.
       */
      function updateSigninStatus(isSignedIn) {
        if (isSignedIn) {
          authorizeButton.style.display = 'none';
          signoutButton.style.display = 'block';
          listFiles();
        } else {
          authorizeButton.style.display = 'block';
          signoutButton.style.display = 'none';
        }
      }

      /**

       */
      function handleAuthClick(event) {

      auth2.disconnect();
        gapi.auth2.getAuthInstance().signOut();
      }

      /**

       */
      function appendPre(message) {
        var pre = document.getElementById('content');
        var textContent = document.createTextNode(message + '\n');
        pre.appendChild(textContent);
      }

      /**

       */
      function listFiles() {
        gapi.client.drive.files.list({
          'pageSize': 10,
          'fields': "nextPageToken, files(id, name)"
        }).then(function(response) {
          appendPre('Files:');
          var files = response.result.files;
          if (files && files.length > 0) {
            for (var i = 0; i < files.length; i++) {
              var file = files[i];
              appendPre(file.name + ' (' + file.id + ')');

根据此文档，当您的应用程序需要访问用户数据时，它会要求 Google 提供特定的访问范围。

范围https://www.googleapis.com/auth/drive.file以一种实用的方式达到了这种平衡。据推测，出于他们理解的原因，用户只使用他们信任的应用程序打开或创建文件。

如此处所述，对文件和文件夹的访问由访问控制列表 (ACL) 确定。ACL 是一个权限列表，用于确定用户是否可以对文件执行操作，例如读取或写入。您可以查看权限指南以获取有关权限和角色的更多详细信息。
