How to upload and delete files with google drive API using python requests

Question:

I’m trying to upload a image to google drive using requests, but it’s not working because the requests keep giving me a status 401 (wrong credentials). I am using the access token that was given to me, so I don’t know what is going on.

There’s my code:

tokendrive = TOKEN_DRIVE
url = "site_url"
myid = MY_ID
subid = MY_SUB_ID
r = requests.get(url)
headers = {'Authorization': 'Bearer ' + tokendrive} 
para = {"name": submission.id + ".png",
        "parents": [myid]}
files = {"data": ("metadata", json.dumps(para), "application/json; charset=UTF-8"),
         "file": io.BytesIO(requests.get(url).content)}
response = requests.post("https://www.googleapis.com/upload/drive/v3/files",headers=headers,files=files)
print(response.text)

Answers:

I believe your goal and your current situation as follows.

  • You want to upload a file to Google Drive.
  • You want to delete a file on Google Drive.
  • You want to achieve this using request module of python.
  • From your endpoint, you want to use Drive API v3.
  • Your access token can be used for uploading and deleting the file using Drive API.

Modification points:

  • If your access token can be used for uploading a file to Google Drive, it is required to modify the script for using the access token. In this case, please modify Token to Bearer. I thought that the reason of your error might be due to this.
  • When Drive API v3 is used, the property of parents is "parents": [myid]. And in the current stage, please use one folder ID here.
  • In the case of Drive API v3, the filename can be given with name instead of title. title is used for Drive API v2.

When above points are reflected to your script, it becomes as follows.

Modified script:

This modified script uploads a file of to Google Drive. Before you use this script, please confirm the variables you want to use, again.

headers = {'Authorization': f'Bearer {tokendrive}'} # or 'Bearer ' + tokendrive
para = {
    "name": "image_url.jpg",
    "parents": [myid]
}
files = {
    "data": ("metadata", json.dumps(para), "application/json; charset=UTF-8"),
    "file": io.BytesIO(requests.get(submission.url).content)
}
response = requests.post(
    "https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart",
    headers=headers,
    files=files
)
print(response.text)

  • In this script, the following value is returned.

      {
   "kind": "drive#file",
   "id": "###",
   "name": "image_url.jpg",
   "mimeType": "image/jpeg"
  }

  • In this modified script, the maximum file size for uploading is 5 MB. When you want to upload a file over 5 MB, please use resumable upload. In that case, I think that this thread might be useful. Ref

Sample script:

This sample script deletes a file on Google Drive.

fileId = '###' # Please set the file ID you want to delete.
headers = {'Authorization': f'Bearer {tokendrive}'} # or 'Bearer ' + tokendrive
response = requests.delete(
    "https://www.googleapis.com/drive/v3/files/" + fileId,
    headers=headers,
)
print(response.text)

  • In this case, no value is returned. This is the current specification.

  • IMPORTANT: This script completely deletes the file of fileId. So please be careful this. I would like to recommend to test using a sample file.
