无法在 Go 中使用 Google Drive API 下载文件

Question

I am trying to download some *.FIT files using Google Drive API for Go, from a private folder stored in my Google Drive. (Garmin 310XT data)

I have followed the wizard and guide found here , and have successfully obtained a full list of files from a folder by id.

I am using this sample code , but I cannot download any of the files. Both the file DownloadUrl and the ExportFormats properties are always empty. Has anyone successfully done this, or am I just missing something important?

Edit: The first problem was about scope, but after changing it to drive.DriveScope I can only download 0 byte files.

Solved

Using the correct http.RoundTripper solved the 0 byte size issue. (client.Transport)

Answer 1

Is the file restricted?

See files docs under labels.restricted

labels.restricted boolean Whether viewers and commenters are prevented from downloading, printing, and copying this file.
