  • 生成微博授权URL及回调地址

    1.创建apps/oauth模块进行oauth认证

    '''2.1 在apps文件夹下新建应用: oauth'''
    cd syl/apps
    python ../manage.py startapp oauth # 切换到apps文件夹下执行创建命令
    '''2.2 添加子路由: oauth/urls.py'''
    from django.urls import path
    from . import views
    urlpatterns = [
    ]
    '''2.3 在syl/settings.py中添加应用'''
    INSTALLED_APPS = [
    'oauth.apps.OauthConfig',
    ]
    '''2.4 在syl/urls.py主路由中添加'''
    urlpatterns = [
    path('oauth/', include('oauth.urls')),
    ]
    

    2.生成微博授权URL接口

    1.1 添加子路由: oauth/urls.py

    urlpatterns = [
    path('weibo/', views.WeiboUrl.as_view()), # /oauth/weibo/ 返回微博登录地址
    ]
    

    1.2 syl/settings.py 中配微博地址

    WEIBO_CLIENT_ID = '3516473472'
    WEIBO_REDIRECT_URL = 'http://127.0.0.1:8888/oauth/callback/'
    

    1.3 视图函数: oauth/views.py

    from rest_framework.permissions import AllowAny
    from rest_framework.response import Response
    from rest_framework.views import APIView
    from urllib.parse import urlencode
    
    # 生成前端跳转到微博扫码页面的url
    class WeiboUrl(APIView):
        '''
        生成微博的登陆页面路由地址
        https://api.weibo.com/oauth2/authorize? # 微博oauth认证地址
        client_id=4152203033& # 注册开发者id
        response_type=code&
        redirect_uri=http://127.0.0.1:8888/oauth/callback/ # 获取code后将code回
        调给后端地址
        '''
    # 自定义权限类
        permission_classes = (AllowAny,)
    
    
        def post(self, request):
            url = 'https://api.weibo.com/oauth2/authorize?'  # 微博授权的url地址
            data = {
                'client_id': '3847987228',  #settings.WEIBO_CLIENT_ID
                'response_type': 'code',
                'redirect_uri': 'http://127.0.0.1:8888/oauth/callback/',  # VUE的回调,微博后台授权的回调地址
        }
            weibo_url = url + urlencode(data)# https://api.weibo.com/oauth2/authorize?
        # client_id = 4152203033 & response_type = code & redirect_uri = http: // 127.0.0.1: 8000 / api / weibo_back /
        # return Response({'weibo_url': weibo_url})
            return Response({'code': '0', 'msg': '成功', 'data': {'url': weibo_url}})
    

    3.测试生成微博售前URL接口

    • 测试接口获取新浪微博地址
      http://192.168.56.100:8888/oauth/weibo/

    1.在Vue页面加载时动态发送请求获取微博授权url

    1.1 在 componentscommonlab_header.vue 中写oauth动态获取微博授权URL

    // 获取微博登录地址
    oauth() {
    // 从后端获取 微博登录地址
    oauth_post().then((resp) => {
    console.log(resp)
    //{'code': '0', 'msg': '成功', 'data': {'url': url}}
    let url = resp.data.url;
    this.weibo_url = url;
    })
    },
    

    1.2 在vue的mounted函数中调用获取微博授权url函数

    mounted() {
    this.oauth()
    },
    
    

    1.3 点击"登录"弹出的form表单中加入url

    <form
    action="/login"
    method="post"
    >
    <div class="form-group widget-signin">
    <a :href="weibo_url"><i class="fa fa-weibo"></i></a>
    </div>
    </form>
    

    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': '3847987228',
            'client_secret': '538c1fb220cdad5cd35bafe26e80ec03',
            '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('uid') # 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)
                #1.3 oauth/models.py 中添加用户绑定模型
                #1.4 迁移数据库
                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)
    

    1.4 迁移数据库

    python manager.py makemigrations
    python manager.py migrate
    

    1.vue微博回调空页面

    1.1 页面路径 componentsoauth.vue

    <template>
    <div>
    <p>跳转中....</p>
    </div>
    </template>
