21.生成微博授权url

一、django后端

1. 创建apps/oauth模块进行OAuth认证

# 1.在apps文件夹下创建新应用：oauth
cd syl/apps
python ../manage.py startapp oauth		# 切换到apps文件夹下执行创建命令

# 2.syl/urls.py主路由中添加
urlpatterns = [
    path('oauth/', include('oauth.urls')),
]

# 3.在syl/settings.py中添加应用
INSTALLED_APPS = [
    'oauth.apps.OauthConfig',
]

# 4.添加子路由： oauth/urls.py
from django.urls import path
from . import views
urlpatterns = [
    
]

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 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


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': '2567752731',  # WEIBO_APP_KEY,
            '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. 测试生成微博授权URL接口

• 测试接口获取新浪微博地址

• 在浏览器访问返回地址即可回到新浪扫码界面

https://api.weibo.com/oauth2/authorize?client_id=2567752731&response_type=code&redirect_uri=http%3A%2F%2F127.0.0.1%3A8888%2Foauth%2Fcallback%2F###

二、vue前端

1. 在vue页面挂载时动态发送请求获取微博授权url

1.1 在 components\common\lab_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oauth()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>
