Python-使用OAuth 2.0服務客戶端訪問Google電子表格時出現問題

Question

我擁有一個Google電子表格，我正在嘗試使用gspread和oauth2client通過一個小的OAuth 2.0 Python服務客戶端進行訪問。

我已經在Google Developers Console上創建了OAuth 2.0服務帳戶，並與該電子郵件共享了電子表格，從而使客戶端/應用程序可以訪問該電子表格，並將包含憑據的JSON密鑰文件放在一個小的測試腳本中。 盡管我可以構造OAuth 2.0憑據對象，甚至可以獲取電子表格客戶端，但是在客戶端上調用openall()時，仍然存在XML解析錯誤：

File "<stdin>", line 1, in <module>
File "/Library/Python/2.7/site-packages/gspread/client.py", line 214, in openall
  feed = self.get_spreadsheets_feed()
File "/Library/Python/2.7/site-packages/gspread/client.py", line 230, in get_spreadsheets_feed
  return ElementTree.fromstring(r.read())
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 1301, in XML
  return parser.close()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 1654, in close
  self._raiseerror(v)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 1506, in _raiseerror
  raise err
xml.etree.ElementTree.ParseError: no element found: line 1, column 0

這是代碼：

import gspread
from gspread import Client
from gspread.httpsession import HTTPSession
from oauth2client.client import SignedJwtAssertionCredentials

OAuth2_JSON_key = {
  "client_auth_scope": "https://spreadsheets.google.com/feeds",
  "myspreadsheet_keys":
  {
    "myspreadsheet_key": "XXXX"
  },
  "private_key_id": "XXXX",
  "private_key": "XXXX",
  "client_email": "XXXXgkcvcke@developer.gserviceaccount.com",
  "client_id": "XXXXgkcvcke.apps.googleusercontent.com",
  "client_type": "service_account"
}

OAuth2_credentials = SignedJwtAssertionCredentials(
    OAuth2_JSON_key['client_email'],
    OAuth2_JSON_key['private_key'],
    OAuth2_JSON_key['client_auth_scope']
)

persistent_session = HTTPSession(headers={'Connection':'Keep-Alive'})

spreadsheet_client = gspread.Client(
    auth=OAuth2_credentials,
    http_session=persistent_session
)

spreadsheets = spreadsheet_client.openall()

Answer 1

我對此不太熟悉，但是我遇到了類似的錯誤。 您應該嘗試從Google開發者控制台下載json密鑰並運行以下命令：

json_key = json.load(open('****.json'))  #Downloaded from google
credentials = SignedJwtAssertionCredentials(json_key['client_email'],   json_key['private_key'], scope)
gc = gspread.authorize(credentials)

通過這種方式訪問​​電子表格我沒有任何錯誤。 不要忘記與客戶電子郵件共享電子表格。

Answer 2

從我可以看到的，將insert_row與gpsread.Client()方法一起使用會引起問題。 我將代碼切換回gspread.authorize() ，它工作得很好。
