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 = "ya29.A0AfH6SMDn1ti-5u8gjLQhHf3ffILkR2_8mSRBoap7hY8ZuIGoFomPhZJAi_hVgORZkBJtBeTDhlPnOeksNZvwrUPgBcuHle5BMqULMBY7Y97fIaMGuOqSAQIrSyXnqLbtDLEwrnCAXfHHSVxtWAbX80pHkarG"
url = "https://www.reddit.com/r/LiminalSpace/comments/lwoipa/i_guess_nobody_woke_me_up/"
myid = "1QoepljKHkjSarx0kCcwEnHjRA5fBP4sU"
subid = lwoipa
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)

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.
