Django 1.7 google oauth2令牌验证失败

本文介绍了Django 1.7 google oauth2令牌验证失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试通过验证Google令牌来访问Django应用程序中的用户日历的过程。虽然我已经在网路上发现了几个迹象，但我遇到了一个400错误代码回应我的回调函数（Bad Request）。

往复m oauth2client.django_orm import FlowField，CredentialsField [...] class Credentials（models.Model）： id = models.ForeignKey（User，primary_key = True） credential = CredentialsField（） class Flow（models.Model）： id = models.ForeignKey（User，primary_key = True） flow = FlowField（）

我下载了 client_secrets.json 文件直接从Google开发者控制台。 开发者控制台中指定的客户端ID类型是Web应用程序，我认为是正确的。 我注意到的是，如果我删除令牌验证码块：

如果不是xsrfutil.validate_token（ settings.SECRET_KEY，request.REQUEST ['state']，request.user）： return HttpResponseBadRequest（）

一切正常，流程和凭据正确存储在数据库中，我可以阅读日历。我可能会遇到什么问题？

编辑：我还检查了传出（Google）和传入（回调）数据：

OUTGOING ：

请求。用户： admin settings.SECRET_KEY： I_AM_NOT_WRITING_IT_HERE FLOW.params ['state']： SOME_OTHER_RANDOM_STUFF / pre>

收入：

request.user： admin settings.SECRET_KEY： I_AM_NOT_WRITING_IT_HERE FLOW.params ['state']： SOME_OTHER_RANDOM_STUFF

数据是相同的，至少是一个打印到控制台。此外，通过控制台的生成/验证操作正常工作（xsrfutil.validate_token返回True，包括测试和实际数据，包括用户模型实例）。我更加困惑。

解决方案

我已经在几个小时内完全相同的问题，我想出了解决方案@Ryan Spaulding和@Hans Z回答。它的工作原理

这是因为Django 1.7使用request.REQUEST为上面的状态变量返回一个unicode对象。我以前使用过Django 1.6，它用来返回一个字符串。

这里可以找到更多的细节。 github/google/google-api-python-client/issues/58 我写了这篇文章以备将来参考。

如果不是xsrfutil.validate_token（ settings.SECRET_KEY， str（request.REQUEST ['state ']）， request.user）： return HttpResponseBadRequest（）

I'm trying to get through the process of authenticating a Google token for accessing a user's calendar within a Django application. Although I've followed several indications found on the web, I'm stuck with a 400 error code response to my callback function (Bad Request).

views.py

# -*- coding: utf-8 -*- import os import argparse import httplib2 import logging from apiclient.discovery import build from oauth2client import tools from oauth2client.django_orm import Storage from oauth2client import xsrfutil from oauth2client.client import flow_from_clientsecrets from django.http import HttpResponse from django.http import HttpResponseBadRequest from django.http import HttpResponseRedirect from django.shortcuts import render_to_response from django.core.urlresolvers import reverse from django.contrib import auth from django.contrib.auth.decorators import login_required from django.conf import settings from apps.tecnico.models import Credentials, Flow CLIENT_SECRETS = os.path.join( os.path.dirname(__file__), '../../client_secrets.json') @login_required def index(request): storage = Storage(Credentials, 'id', request.user, 'credential') FLOW = flow_from_clientsecrets( CLIENT_SECRETS, scope='www.googleapis/auth/calendar.readonly', redirect_uri='MY_URL:8000/oauth2/oauth2callback' ) credential = storage.get() if credential is None or credential.invalid is True: FLOW.params['state'] = xsrfutil.generate_token( settings.SECRET_KEY, request.user) authorize_url = FLOW.step1_get_authorize_url() f = Flow(id=request.user, flow=FLOW) f.save() return HttpResponseRedirect(authorize_url) else: http = httplib2.Http() http = credential.authorize(http) service = build(serviceName='calendar', version='v3', http=http, developerKey='MY_DEV_KEY_FROM_GOOGLE_CONSOLE') events = service.events().list(calendarId='primary').execute() return render_to_response('calendario/welcome.html', { 'events': events['items'], }) @login_required def auth_return(request): if not xsrfutil.validate_token( settings.SECRET_KEY, request.REQUEST['state'], request.user): return HttpResponseBadRequest() storage = Storage(Credentials, 'id', request.user, 'credential') FLOW = Flow.objects.get(id=request.user).flow credential = FLOW.step2_exchange(request.REQUEST) storage.put(credential) return HttpResponseRedirect("MY_URL:8000/caly")

models.py

from oauth2client.django_orm import FlowField, CredentialsField [...] class Credentials(models.Model): id = models.ForeignKey(User, primary_key=True) credential = CredentialsField() class Flow(models.Model): id = models.ForeignKey(User, primary_key=True) flow = FlowField()

I've downloaded the client_secrets.json file directly from the Google Dev Console. The specified Client ID type in the Dev Console is "web application", which I think is correct. What I've noticed is, if I remove the token validation code block:

if not xsrfutil.validate_token( settings.SECRET_KEY, request.REQUEST['state'], request.user): return HttpResponseBadRequest()

everything works correctly, flow and credentials get correctly stored in the database and I'm allowed to read the calendar. What can I possibly be wrong with?

EDIT: I've also checked outgoing (to Google) and incoming (to callback) data:

OUTGOING:

request.user: admin settings.SECRET_KEY: I_AM_NOT_WRITING_IT_HERE FLOW.params['state']: SOME_OTHER_RANDOM_STUFF

INCOMING:

request.user: admin settings.SECRET_KEY: I_AM_NOT_WRITING_IT_HERE FLOW.params['state']: SOME_OTHER_RANDOM_STUFF

Data is identical, at least to a print to console. Also, the generation/validation operations via console work correctly (xsrfutil.validate_token returns True, both with test and real data, including User model instances). I'm even more puzzled.

解决方案

I have struggled exact the same issue for several hours, and I figured out the solution of which @Ryan Spaulding and @Hans Z answered. It works!

This is due to the fact Django 1.7 returns a unicode object for the state variable above using request.REQUEST. I was previously using Django 1.6 which used to return a string.

One can find more detail here. github/google/google-api-python-client/issues/58 I wrote this post for future reference.

if not xsrfutil.validate_token( settings.SECRET_KEY, str(request.REQUEST['state']), request.user): return HttpResponseBadRequest()
