去微信服务器取openid和session_key

class UserCreate(generics.CreateAPIView):
    serializer_class = UserSerializer
    def create(self, request, *args, **kwargs):
 js_code = self.request.data['code']
 appid=''
 secret=''
 requestString='https://api.weixin.qq.com/sns/jscode2session?appid={APPID}&secret={SECRET}&js_code={JSCODE}&grant_type=authorization_code'.format(APPID=appid,SECRET=secret,JSCODE=js_code)
 r = requests.get(requestString)
 r=r.json()
 print(r['openid'])

r

r.json

要取出值使用

r=r.json
r['openid']

class UserCreate(generics.CreateAPIView):
    serializer_class = UserSerializer
    def create(self, request, *args, **kwargs):
 js_code = self.request.data['code']
 appid=''
 secret=''
 requestString='https://api.weixin.qq.com/sns/jscode2session?appid={APPID}&secret={SECRET}&js_code={JSCODE}&grant_type=authorization_code'.format(APPID=appid,SECRET=secret,JSCODE=js_code)
 r = requests.get(requestString)
 r=r.json()
 openid=r['openid']
 #User是Django自带的用户管理表，通过from django.contrib.auth.models import User引入
 #Token表from rest_framework.authtoken.models import Token,我用了Django rest framework
 #下面代码的逻辑：从User表取出/创建一条username=openid的记录，然后根据User表的这条记录取出/创建token表的一条记录。这样User表中每个用户都有一个token.
 try:
     #如果注册了，可以直接从User表获取到记录
     auth_user = User.objects.get(username=openid)
 except:
     #如果没有注册就现在create
     auth_user = User.objects.create(username=openid)
 try:
     #如果token表有token值就取token出来
     token = Token.objects.get(user=auth_user)
 except:
     #如果token表没有token值就创建token
     token = Token.objects.create(user=auth_user)
 return Response(token.key, status=status.HTTP_201_CREATED)
