android – 401 Unauthorized error.Failed将授权代码升级为凭证对象

我在我的Android应用程序中使用oauth 2.0与混合流程进行谷歌登录https://developers.google.com/identity/sign-in/web/server-side-flow.我将一次授权代码放入android应用程序并通过postman将其发布到我的flask api.当我在api中将flow.step2_exchange应用于此一次auth代码时,它会给我流量交换错误.我已经检查了到达api的auth代码与我在应用程序中获得的代码相同.我找不到错误的原因.

我的一次授权代码如下所示：4 / qXilPdy7xOVe5swCBlVRrxjuVu8zEzfcmidlooo7_ls

我的烧瓶api的代码片段：

# IMPORTS FOR THIS STEP
from oauth2client.client import flow_from_clientsecrets
from oauth2client.client import FlowExchangeError
import httplib2
import json
from flask import make_response
import requests


app = Flask(__name__)

CLIENT_ID = json.loads(
    open('client_secrets.json', 'r').read())['web']['client_id']
APPLICATION_NAME = "OAUTH_SERVER"
SCOPES = [
    'https://www.googleapis.com/auth/gmail.readonly',
    'https://www.googleapis.com/auth/userinfo.email',
    'https://www.googleapis.com/auth/userinfo.profile',
    # Add other requested scopes.
]

# Connect to Database and create database session
engine = create_engine('sqlite:///restaurantmenu.db')
Base.metadata.bind = engine

DBSession = sessionmaker(bind=engine)
session = DBSession()

@app.route('/gconnect', methods=['POST'])
def gconnect():
    request.get_data()
    code = request.data.decode('utf-8')
    print (code)

    # Upgrade the authorization code into a credentials object
    oauth_flow = flow_from_clientsecrets('client_secrets.json', scope = SCOPES)
    oauth_flow.redirect_uri = 'postmessage'
    try:
        credentials = oauth_flow.step2_exchange(code)
        if credentials is None:
            print ("it is empty")
    except FlowExchangeError:
        response = make_response(
            json.dumps('Failed to upgrade the authorization code.'), 401)
        response.headers['Content-Type'] = 'application/json'
        return response

我对Api的client_secret.json命名为OAUTH_SERVER,它如下：

{"web":
      {"client_id":"matches the one in console.apps.googleusercontent.com",
"project_id":"oauthapi",
"auth_uri":"https://accounts.google.com/o/oauth2/auth",
"token_uri":"https://accounts.google.com/o/oauth2/token",
"auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
"client_secret":"###########",
"redirect_uris["http://localhost:5000/gconnect","http://localhost:5000/"],
"javascript_origins":["http://localhost:5000"]}
}

解决方法:

我认为这是来自Udacity课程 – 身份验证&授权.请检查login.html是否包含正确的data-clientid值.我有同样的问题,因为复制后忘了改变我的.
