微博回调接口(django)

1.1 oauth/urls.py 中添加路由

urlpatterns = [ 
    path('weibo/callback/', views.OauthWeiboCallback.as_view()), 
# /oauth/weibo/callback/ ]    

1.2 oauth/views.py 中添加试图函数

http://192.168.56.100:8888/oauth/weibo/callback/
from .models import OauthUser
from rest_framework_jwt.serializers import jwt_payload_handler, jwt_encode_handler
from user.utils import jwt_response_payload_handler


# 通过vue前端传入的code,微博身份验证
class OauthWeiboCallback(APIView):
    # 自定义权限类
    permission_classes = (AllowAny,)
    def post(self, request):
    # 接收vue端传过来的code(微博的用户code)
    # 1.使用微博用户code+微博开发者账号信息换取微博的认证access_token
        code = request.data.get('code')
        data = {
            'client_id': '3222390457',
            'client_secret': '3887fc19b7564b7ea9e75bfe7250f30d',
            'grant_type': 'authorization_code',
            'code': code,
            'redirect_uri': 'http://127.0.0.1:8888/oauth/callback/',
        }
        url = 'https://api.weibo.com/oauth2/access_token'
        data = requests.post(url=url, data=data).json() # 拿取请求的返回结果
        access_token = data.get('uid') # 获取到的微博token
        weibo_uid = data.get('access_token') # 获取到少码用户的id

    # 2. 根据uid 查询绑定情况
        try:
            oauth_user = OauthUser.objects.get(uid=weibo_uid, oauth_type='1')
        except Exception as e:
            oauth_user = None
        # 返回动作, 登录成功/需要绑定用户 type 0 登录成功, 1, 授权成功, 需要绑定
        if oauth_user:
            # 4. 如果绑定了, 返回token, 登录成功
            user = oauth_user.user
            payload = jwt_payload_handler(user)
            token = jwt_encode_handler(payload)
            # jwt_response_payload_handler为user模块定义的jwt返回的信息
            data = jwt_response_payload_handler(token, user)
            data['type']='0'  #指定为登录成功
            return Response({"code":0,"msg":"登录成功",'data':data})
        else:
            return Response({"code":0,"msg":"授权成功",'data':{'type':1,'uid':weibo_uid}})

1.3 oauth/models.py 中添加用户绑定模型

# 把三方的用户信息,和本地的用户信息进行绑定
class OauthUser(models.Model):
    OAUTHTYPE = ( ('1', 'weibo'), ('2', 'weixin'), )
    uid = models.CharField('三方用户id', max_length=64)
    # 三方用户id
    user = models.ForeignKey('user.User', on_delete=models.CASCADE)
    # 本地用户外键,关联User表
    oauth_type = models.CharField('认证类型', max_length=10, choices=OAUTHTYPE)
