我正在尝试通过 Microsoft Flow 的过程下载一个填充到 Google Drive 文件夹的 .csv 文件，该过程每 6 小时通过电子邮件检索一个电子邮件附件文档。我试图遵循使用 Pydrive 模块的文档。我知道如何创建文件以上传和下载到 Google Drive，但不知道如何根据现有文件的链接 URL 下载。这是我的代码。

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LocalWebserverAuth()

drive = GoogleDrive(gauth)

file_obj = drive.CreateFile({'id': '1j2vJVOB-_Xltmp9xkQJZzGb-5DAB_Imu'})
print(file_obj["title"], file_obj["mimeType"])
file_obj.GetContentFile('Assigned_Agency_AZS_Overhead_EXCEL.csv', mimetype='text/csv')

我收到的错误消息是。

    runfile('C:/Google_Python_Test/Google/Google_Drive1.py', wdir='C:/Google_Python_Test/Google')

您可能需要指定文件的MIME类型以确保正确下载文件。如果您绝对确定该文件是 acsv并且未转换为 Google 文档，那么您可以执行以下操作：

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LocalWebserverAuth()

drive = GoogleDrive(gauth)

file_obj = drive.CreateFile({'id': '1j2vJVOB-_Xltmp9xkQJZzGb-5DAB_Imu'})
file_obj.GetContentFile('Assigned_Agency_AZS_Overhead_EXCEL.csv', mimetype='text/csv')
