05.微博回调接口
微博回调接口
1oauth/urls.py中添加路由
urlpatterns = [
path('weibo/callback/', views.OauthWeiboCallBack.as_view()),
]
2oauth/views.py中添加视图函数
import requests
from .models import OauthUser
from rest_framework_jwt.serializers import jwt_payload_headler, 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):
code = request.data.get('code')
data = {
'client_id': '888888888',
'client_secret': 'xxxxxxxxxxxxxxxxxxx',
'code': code,
'redirct_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
weibo_uid = data.get('uid') # 获取到微博uid
access_token = data.get('access_token') # 获取微博token
# 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， type 1授权成功，需要绑定
if oauth_user:
# 如果已经绑定，直接登录成功，返回token
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:
# 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}})
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'),
('3', 'QQ')
)
uid = models.CharField('三方用户的id', max_length=64) # 三方用户id
user = models.ForeignKey('user.User', ondelete=models.CASCADE) # 关联user表外键
oauth_type = models.CharField('认证类型', max_length=10, choices=OAUTHTYPE) # 枚举类型使用的那个三方
4.进行数据库迁移
python manage.py makemigrations
python manage.py migrate
