Google Picker 无法始终加载预览图像

Question

我设置了一个 Google Docs Picker 以允许用户从 Google Drive 中选择图像或上传它们。

加载选择器后，网格视图中的某些图像预览不会加载。这似乎是随机的，错误是 404（未找到）。为格式的 url 返回 404 https://googledrive.com/thumb/fileId?access_token=ya....&size=180

这是我可以在我的 JavaScript 代码中解决的问题吗？请参阅下面的代码。

var driveView = new google.picker.DocsView(google.picker.ViewId.DOCS_IMAGES);
driveView.setParent(driveFolderId); //sets the default displayed folder

var uploadView = new google.picker.DocsUploadView();
uploadView.setParent(driveFolderId); //set upload parent folder and prevents the user from changing it
uploadView.setMimeTypes('image/png,image/jpeg'); //image/bmp,image/gif,image/tiff 
//default file type to png and jpeg

var picker = new google.picker.PickerBuilder()
  //.enableFeature(google.picker.Feature.NAV_HIDDEN) //hide navigation
  .enableFeature(google.picker.Feature.MULTISELECT_ENABLED) // multi select - bug must be enabled to set the upload folder destination
  .addView(driveView) //allows picking files from Google Drive
  .addView(uploadView) //allows uploads
  .setOAuthToken(gapi.auth.getToken().access_token)
  .setCallback(imagePickerCallback)
  .build();

picker.setVisible(true);

提前致谢。

找到this similar question 后，我更改了我的OAUTH 登录过程以包含https://www.googleapis.com/auth/drive.readonly 范围，它开始工作。我只是要求 drive.file。
