收到 InvalidClientIdError (invalid_request) 不匹配的重定向 URI。使用 requests_oauthlib

Question

我正在尝试使用库 requests_oauthlib 模拟消费者和提供者 (server_to_server) 之间的令牌交换。我在提供方授权后收到代码并将代码交换为令牌后出现错误。

所以我在我的回调函数中得到了我的代码，但它说重定向 uri 不匹配。我已经检查了提供商数据库中的重定向 uri。他们是一样的。（作为下面代码中的变量 redirect_uri）

查看我的 Django 实现：

views.py

# create session
from importlib import import_module
SessionStore = import_module(settings.SESSION_ENGINE).SessionStore
session = SessionStore()

client_id = "123456"
client_secret = "123456"
authorization_base_url = 'http://localhost:8000/o/authorize/'
token_url = 'http://localhost:8000/o/token/'

redirect_uri = 'http://localhost:8888/callback'

# ONLY FOR A LOCALHOST
import os
os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'


def index(request):
    provider = OAuth2Session(client_id, redirect_uri=redirect_uri)
    authorization_url, state = provider .authorization_url(authorization_base_url)

    # state is used to prevent CSRF, keep this for later.
    session['oauth_state'] = state
    # redirect to provider    
    return redirect(authorization_url)

def callback(request):
    # handles code from provider and redirects to profile page
    redirect_response = request.build_absolute_uri()
    # (http://localhost:8888/callback?code=123456&state=SomeStateCode)

    state = session.get('oauth_state')
    laas = OAuth2Session(client_id, state=state)

    token = laas.fetch_token(token_url,
                     client_secret=client_secret,
                     authorization_response=redirect_response) # here is mismatch error    
    session['oauth_token'] = token    
    return HttpResponseRedirect(reverse('app:profile'))



def profile(request):
    # shows access token if existing
    if session.get('oauth_token') is not None:
        return HttpResponse("Token: " + session.get('oauth_token'))
    return HttpResponse('No token')

这是来自消费者的错误堆栈跟踪：

有什么帮助吗？谢谢！

Answer 1

我知道了，你也需要在回调函数中将 "redirect_uri " 传递给 OAuth2Session。 OAuth2Session(client_id, state=state, redirect_uri=redirect_uri**)

Answer 2

我使用的是不同的库，但通过传递 redirect_uri 参数可以使用相同的方法，该参数不在 Google API 文档的原始示例中。

    flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
    CLIENT_SECRET_FILE,
    scopes=GDRIVE_API_SCOPE,
    state=state,
    redirect_uri=GDRIVE_REDIRECT_URI)

收到 InvalidClientIdError (invalid_request) 不匹配的重定向 URI。使用 requests_oauthlib
