我正在尝试通过Python客户端使用此代码访问谷歌应用程序以获得授权(私人信息显然已编辑):

import gflags
import httplib2

from apiclient.discovery import build
from oauth2client.file import Storage
from oauth2client.client import SignedJwtAssertionCredentials
from oauth2client.tools import run

f = open('privatekey.p12', 'rb')
key = f.read()
f.close()
credentials = SignedJwtAssertionCredentials(
    service_account_name='name@developer.gserviceaccount.com',
    private_key=key,
    scope = 'https://www.googleapis.com/auth/calendar')
http = httplib2.Http()
http = credentials.authorize(http)
service = build(serviceName='calendar', version='v3', http=http)

但是我收到了这个错误:

ImportError: cannot import name SignedJwtAssertionCredentials

我安装了Google v3 API Python客户端以及OAuth2; 我似乎没有对这些模块有任何其他问题,尽管我没有太多使用它们.有谁知道发生了什么？

我正在尝试在GAE Python中实现Google Identity Toolkit(gitkitv3).用户登录网站后,我收到以下错误:

'PKCS12 format is not supported by the PyCrpto library. '
NotImplementedError: PKCS12 format is not supported by the PyCrpto library. Try converting to a "PEM" (openssl pkcs12 -in xxxxx.p12 -nodes -nocerts > privatekey.pem) or using PyOpenSSL if native code is an option.

基于SO回复,我在x.p12文件上运行以下命令,并使用生成的privatekey.pem文件:

openssl pkcs12 -passin pass:notasecret -in x.p12 -nocerts -passout pass:notasecret -out key.pem 
openssl pkcs8 -nocrypt -in key.pem -passin pass:notasecret -topk8 -out privatekey.pem

现在,我收到以下错误:

'X509 certs are not supported by the PyCrypto library. …
