不显示使用 Oauth 2.0 服务帐户上传的文件

Question

尝试使用Oauth 2.0 server to server authentication（使用service account）将文件上传到谷歌驱动器。使用了他们的示例代码作为参考，生成的脚本是这样的：

import httplib2
import pprint
import sys
from apiclient.discovery import build
from oauth2client.client import SignedJwtAssertionCredentials
from apiclient.http import MediaFileUpload

def main(argv):
    # Load the key in PKCS 12 format that you downloaded from the Google API
    # Console when you created your Service account.
    f = open('key.p12', 'rb')
    key = f.read()
    f.close()

    # Check https://developers.google.com/drive/scopes for all available scopes
    OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'

    # Path to the file to upload
    FILENAME = 'testfile.txt'

    # Create an httplib2.Http object to handle our HTTP requests and authorize it
    # with the Credentials. Note that the first parameter, service_account_name,
    # is the Email address created for the Service account. It must be the email
    # address associated with the key that was created.
    credentials = SignedJwtAssertionCredentials(
        'xxxxx-xxxxxxx@developer.gserviceaccount.com',
        key,
        OAUTH_SCOPE)
    http = httplib2.Http()
    http = credentials.authorize(http)

    drive_service = build('drive', 'v2', http=http)

    # Insert a file
    media_body = MediaFileUpload(FILENAME, mimetype='text/plain', resumable=True)
    body = {
        'title': 'My document',
        'description': 'A test document',
        'mimeType': 'text/plain'
    }

    fil = drive_service.files().insert(body=body, media_body=media_body).execute()
    pprint.pprint(fil)

if __name__ == '__main__':
main(sys.argv)

脚本似乎运行正常（没有错误，pprint 显示的输出似乎很好）。但是，该帐户的谷歌驱动器页面不显示上传的文件。当尝试从 pprint 输出访问其中一个链接以查看文件时，我从 Google Drive 收到“您需要许可”消息，这很奇怪，因为我已登录到创建服务帐户的帐户。

Answer 1

该文件归服务帐户所有，而不是您的 Google 帐户。服务帐户有自己的 5GB 空间用于 Google 云端硬盘。

您需要与您的用户帐户共享文件或拥有服务帐户impersonate your user account（假设您在 Google Apps 域中），以便该文件由您的用户帐户创建和拥有。
