05.微博回调接口

1.微博回调接口

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': '3516473472', 
            'client_secret': '7862ee35a0dc6f0345d0464dc34f14fc', 				'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:
            # 5. 如果没绑定, 返回标志, 让前端跳转到绑定页面
            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)
# 1,2 ...

1.4 迁移数据库

python manager.py makemigrations 
python manager.py migrate
