我想使用gspread
模块从Python编辑Google表格。 setup instructions包含以下示例:
import gspread
from oauth2client.service_account import ServiceAccountCredentials
scope = ['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
credentials = ServiceAccountCredentials.from_json_keyfile_name('gspread-april-2cd … ba4.json', scope)
gc = gspread.authorize(credentials)
但是,根据https://pypi.org/project/oauth2client/,oauth2client
库已过时。因此,我尝试使用google-auth
对此进行如下修改:
import gspread
from google.oauth2 import service_account
credentials = service_account.Credentials.from_service_account_file(
'my_client_secrets.json')
scoped_credentials = credentials.with_scopes(
['https://www.googleapis.com/auth/spreadsheets'])
gc = gspread.authorize(scoped_credentials)
不幸的是,我遇到了以下错误:
(lucy-web-CVxkrCFK) bash-3.2$ python nps.py
Traceback (most recent call last):
File "nps.py", line 54, in <module>
gc = gspread.authorize(scoped_credentials)
File "/Users/kurtpeek/.local/share/virtualenvs/lucy-web-CVxkrCFK/lib/python3.7/site-packages/gspread/__init__.py", line 38, in authorize
client.login()

if not self.auth.access_token or \
AttributeError: 'Credentials' object has no attribute 'access_token'
如果我进入调试器,我确实会看到credentials
具有token
属性,但没有access_token
属性:

由Credentials
生成的google-auth
与oauth2client
生成的对象不同吗?

一年半以后,在完全相同的情况下,我发现这对我有用:
import gspread
from google.oauth2 import service_account
from google.auth.transport.requests import AuthorizedSession
credentials = service_account.Credentials.from_service_account_file(
'your_key_file.json')
scoped_credentials = credentials.with_scopes(
['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
)
gc = gspread.Client(auth=scoped_credentials)
gc.session = AuthorizedSession(scoped_credentials)
sheet = gc.open_by_key('key_in_sharelink')
print(sheet.title)
解决方案改编自gspread github中的this post和google-auth
user guide。

根据gspread
文档,gspread.authorize方法仅支持由oauth2client library创建的凭证对象。要使用新的google-auth,gspread应该添加对此的支持。
如果您不想使用已弃用的oauthclient2,则可能的工作方式是利用authlib类的session参数来使用gspread.Client。有一个不错的教程,介绍如何here。

作为临时解决方案,您可以创建一个继承凭证的新类,并添加一个新的access_token
属性,该属性镜像凭证中的令牌。然后将其传递到gspread.authorize
,它应该可以工作。
#Create the new class
class fixed_creds(service_account.Credentials):
def __init__(self, creds):
self.access_token = creds.token
# create new credential object with the access_token
gcreds = fixed_creds(credentials)
# pass new credentials into gspread
sheets = gspread.authorize(gcreds)
# create a new sheet to test it
new_sheet = sheets.create('TestSheet')
# give yourself permission to see the new sheet
sheets.insert_permission(
new_sheet.id,
'youremail@yourdomain.com',
perm_type='user',
role='writer'
)

汤姆提供的创可贴修复不适用于我,因为token
最初是None
在Google OAuth2库中。这是我的创可贴修复程序:
import gspread
import google.auth.transport.requests
from google.oauth2 import service_account
from oauth2client.service_account import ServiceAccountCredentials
class OAuth2ServiceAccountFromGoogleOAuth2(ServiceAccountCredentials): # Hack based upon https://stackoverflow.com/questions/51618127/credentials-object-has-no-attribute-access-token-when-using-google-auth-wi
def __init__(self, google_oauth2_credentials):
self.google_oauth2_credentials = google_oauth2_credentials
self.access_token = google_oauth2_credentials.token
def refresh(self, http):
if self.access_token is None:
request = google.auth.transport.requests.Request()
self.google_oauth2_credentials.refresh(request)
self.access_token = self.google_oauth2_credentials.token
#end if
print(f'access token in {self.access_token}')
#end def
#end class
with open("credentials.json") as gs_key_file:
google_credentials = service_account.Credentials.from_service_account_info(json.loads(gs_key_file.read()), scopes=['https://www.googleapis.com/auth/spreadsheets'])
gclient = gspread.authorize(OAuth2ServiceAccountFromGoogleOAuth2(google_credentials))
