Oauth2.0认证 + 微博三方登陆

Oauth2.0授权认证

oauth2.0是什么？

OAuth（开放授权）是一个开放标准，允许用户让第三方应用访问该用户在某一网站上存储的私密的资源（如照片，视频，联系人列表），而无需将用户名和密码提供给第三方应用。

Oauth2.0的四种授权模式？

• 隐式授权模式（Implicit Grant）

• 授权码授权模式（Authorization code Grant）

• 密码模式（Resource Owner Password Credentials Grant）

• 客户端凭证模式（Client Credentials Grant）

微博三方登陆

微博登陆流程图

1.创建应用(syl/apps)

pyhton ../manage.py  startapp  oauth

2.在syl/setting.py里面配置

INSTALLED_APPS = [
    
    'oauth',

]

WEIBO_APP_KEY = '3909184723'
WEIBO_APP_SECRET = 'd4ca62c699779f0f91bd00c7e7c1197f'
WEIBO_CALL_BACK = 'http://127.0.0.1:8888/oauth/callback/'   # 回调路由

3.apps下oauth/views.py

from urllib.parse import urlencode
import requests
from django.contrib.auth.hashers import make_password
from rest_framework.response import Response
from rest_framework.views import APIView
from oauth.models import WbUser
from user.models import User
from user.views import jwt_response_payload_handler
from rest_framework_jwt.serializers import *

        }

            'code': code,
            'redirect_uri': 'http://127.0.0.1:8888/oauth/callback/'
        }
        url = 'https://api.weibo.com/oauth2/access_token'
        weibo_data = requests.post(url=url, data=data)
        print(type(weibo_data))
        json_weibo_data = weibo_data.json()
        uid = json_weibo_data.get("uid")

                res_data = {

        else:

class BindUser(APIView):
    def post(self,request):
        oauth_type=1

        # 存在绑定用户
        try:
            user=User.objects.filter(username=username).first()
            payload = jwt_payload_handler(user)
            token = jwt_encode_handler(payload)
            data = jwt_response_payload_handler(token, user)
            oauthinfo=WbUser.objects.create(uid=weibo_uid,oauth_type=oauth_type,user=user)
            data={

            }
            res_data={
                "code":0,
                "msg":"登录成功",

            return Response(res_data)

                "data": data
            }
            return Response(res_data)

4.在oauth/urls.py里配置二级路由

# -*- coding: utf-8 -*-
from django.urls import path
from . import views
urlpatterns = [
    path('weibo/', views.WBUrl.as_view(), ),  # 拼接微博url
    path('weibo/callback/', views.WBCallBack.as_view(), ), # 授权回调
    path('weibo/binduser/', views.BindUser.as_view(), ),   # 绑定用户

]
