python - verify_oauth2_token 使用对象作为函数

Question

我正在使用后端进行谷歌身份验证: https://developers.google.com/identity/sign-in/android/backend-auth

看起来有点过时了，最奇怪的是有一行:

idinfo = id_token.verify_oauth2_token(token, requests.Request(), CLIENT_ID)

在实现中，您可以看到在嵌套函数调用中，相同的请求对象到达那里:

def _fetch_certs(request, certs_url):
"""Fetches certificates.

Google-style cerificate endpoints return JSON in the format of
``{'key id': 'x509 certificate'}``.

Args:
    request (google.auth.transport.Request): The object used to make
        HTTP requests.
    certs_url (str): The certificate endpoint URL.

Returns:
    Mapping[str, str]: A mapping of public key ID to x.509 certificate
        data.
"""
response = request(certs_url, method='GET')

request 是一个对象，甚至文档也声明如此，并将其用作函数。我得到的错误是:

TypeError: 'Request' object is not callable

那里应该改变什么？

Answer 1

很可能您调用了错误的 python requests 库。

如果您需要区分 2 个可用的请求库。

from google.auth.transport import requests as google_auth_request
import requests

req = google_auth_request.Request()

idinfo = id_token.verify_oauth2_token(token, req, CLIENT_ID)
