gdrive 上传失败并显示“令牌已过期或撤销”。 如果它使用 crontab 执行但以 root 身份运行 (sudo -s)

Question

I have written a script that uploads/updates an image to my gdrive. It should be executed every 15 min by a crontab entry.

I tested the script as root (sudo -s) and it works and has access to my gdrive. But it does not work when started by my crontab entry. I then get the following message as an error.

Uploading upload.jpg
Failed to upload file: Patch https://www.googleapis.com/upload/drive/v3/files/1y0000hMVV444qjuxC5xqL3hsmyAuoXya?alt=json&fields=id%2Cname%2Csize&uploadType=multipart: oauth2: cannot fetch token: 400 Bad Request
Response: {
  "error": "invalid_grant",
  "error_description": "Token has been expired or revoked."
}

This is my crontab entry

Answer 1

The gdrive command checks a token stored in token_v2.json . The default location for that file is within the user's home.

$HOME/.gdrive/token_v2.json

Using sudo -s changes the user, but the variable $HOME still points to the original user. Running a command with crontab as root checkes for /root/.gdrive/token_v2.json

So the solution is to copy the file token_v2.json to /root/.gdrive/token_v2.json
