如何使用 Google 雲端硬盤 API v3 向 Python 中的共享文件夾進行可續傳上傳？

Question

我正在嘗試使用 Google Drive API v3 和 Python 3.10.4 將文件上傳到 Google Drive。 我正在嘗試進行可恢復的上傳。 我成功獲取了開始上傳的 URI 位置，但是當我嘗試將文件上傳到該位置時，我從 Google 收到了 404 返回。

原因：'notFound'，消息：'找不到文件：#FileIdHere'，位置類型：'參數'，位置：'fileId'

Google 為我提供了我嘗試上傳到的文件夾的 fileId。 它與我從 get_folderId function 獲得的 ID 相同。

def backup(drive: Drive, cam_name: str):
    logger.info('Backup drive has been plugged in')
    logger.info(f'Backing up {drive.letter}')

    #Grab the folder ID of the folder we are uploading files to
    folderId = get_folderId(cam_name)
    access_token = get_access_token()

    rootDirectory = drive.letter + "\\FILE\\"
    if not os.path.isdir(rootDirectory):
        rootDirectory = drive.letter + "\\DCIM"
    for root, dirs, files in os.walk(rootDirectory):
        for fileName in files:
            #Get file path
            filePath = os.path.join(root, fileName)

            #Grab mimetype for file
            mime = magic.Magic(mime=True)
            mimeType = mime.from_file(filePath)

            #Get size of file
            fileSize = os.path.getsize(filePath)

            #Retrieve session for resumable upload
            headers = {"Authorization": "Bearer "+access_token, "Content-Type": "application/json"}
            parameters = {
                "name": fileName,
                "mimeType": mimeType,
                "parents" : [folderId]
                
            }
            response = requests.post(
                    "https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable",
                    headers=headers,
                    data=json.dumps(parameters)
            )
            #Location to upload file
            uploadLocation = response.headers['Location']

            #Upload the file
            headers = {"Content-Range": "bytes 0-" + str(fileSize - 1) + "/" + str(fileSize)}
            response = requests.put(
                uploadLocation,
                headers = headers,
                data=open(filePath, 'rb')
            )
            logger.info(response.text)

在上述 function 的參數變量中，我嘗試添加 supportsAllDrives = True 無濟於事，所以我不確定為什么找不到該文件夾。

#Gets the folder ID of the provided folder name from Google Drive
def get_folderId(cam_name: str):
    service = get_google_service()
    page_token = None
    queryString = "mimeType='application/vnd.google-apps.folder' and name='{}' and trashed = false".format(cam_name)
    response = service.files().list(q = queryString,
                                    spaces='drive',
                                    corpora='drive',
                                    supportsAllDrives=True,
                                    includeItemsFromAllDrives=True,
                                    driveId= #DriveIdGoesHere,
                                    fields='nextPageToken, files(id, name)',
                                    pageToken=page_token).execute()
    folderId = response.get('files')[0].get('id')
    return folderId

#Gets the Google service
def get_google_service():
        SCOPES = ['https://www.googleapis.com/auth/drive']
        SERVICE_ACCOUNT_FILE = 'service.json'
        credentials = service_account.Credentials.from_service_account_file(
                SERVICE_ACCOUNT_FILE, scopes=SCOPES)
        creds = credentials.with_subject(#EmailGoesHere)
        service = build('drive', 'v3', credentials=creds)

        return service

我相信你的目標如下。

• 從How do I do a resumable upload to a shared folder in Python using Google Drive API v3? ，我認為您可能想要將文件上傳到 Google 雲端硬盤中的共享文件夾。
• 從您的顯示腳本來看，您似乎正在使用服務帳戶。
• 但是， Google gives me the fileId of the folder I'm attempting to upload to. Its the same id I get from my get_folderId function. Google gives me the fileId of the folder I'm attempting to upload to. Its the same id I get from my get_folderId function. 。在您的情況下，我認為您可能想要將文件上傳到共享驅動器中的文件夾。

如果我的理解是正確的，從你的錯誤信息reason: 'notFound', message: 'File not found: #FileIdHere', locationType: 'parameter', location: 'fileId' ，下面的修改怎么樣？

從：

response = requests.post(
        "https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable",
        headers=headers,
        data=json.dumps(parameters)
)

到：

response = requests.post(
        "https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&supportsAllDrives=true",
        headers=headers,
        data=json.dumps(parameters)
)

• 當您要上傳文件到共享Drive中的文件夾，且folderId的值為共享Drive中文件夾的文件夾ID時，需要在查詢參數中包含supportsAllDrives=true 。

筆記：

• 當我使用您的端點https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable測試您的腳本時，我確認同樣的錯誤File not found: 。
• 當我使用修改后的端點https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&supportsAllDrives=true測試您的腳本時，我確認可以正確上傳文件。
• 但是，如果您的服務帳戶沒有共享驅動器的寫入權限，則會發生錯誤。 請注意這一點。
