如何通过 python 中安装的 google 驱动器文件的路径获取 file/folder 的共享 link？

Question

我在我的计算机上安装了 Google 驱动器 (Windows 11 x64) 来驱动 G:\ 我希望能够为我有路径的特定 file/folder 获取共享 link。 Google 驱动器将有重复的 file/folder。我怎样才能用 python 做到这一点？提前致谢

已编辑： 我设法获得了特定文件名的 link，但现在如果 Google 驱动器中有 2 个以上具有相同文件名的文件，我就会遇到问题。例如，我想要此文件 G:\RootFolder\Subfolder1\Subfolder2\myfile.txt 的 link，但还有另一个同名文件 G:\RootFolder\Subfolder3\Subfolder4\Subfolder5\myfile.txt。我怎样才能只为 G:\RootFolder\Subfolder1\Subfolder2\myfile.txt 提供 link？

from Google import Create_Service

CLIENT_SECRET_FILE = 'client-secret.json'
API_NAME = 'drive'
API_VERSION = 'v3'
SCOPES = ['https://www.googleapis.com/auth/drive']

service = Create_Service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)

# Update Sharing Setting
file_id = '<file id>'

request_body = {
    'role': 'reader',
    'type': 'anyone'
}

response_permission = service.permissions().create(
    fileId=file_id,
    body=request_body
).execute()

print(response_permission)


# Print Sharing URL
response_share_link = service.files().get(
    fileId=file_id,
    fields='webViewLink'
).execute()

print(response_share_link)

# Remove Sharing Permission
service.permissions().delete(
    fileId=file_id,
    permissionId='anyoneWithLink'
).execute()

我设法创建了适合我的脚本。套餐：pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib

from google.oauth2.credentials import Credentials
