1.建立apps/oauth模組進行oauth認證

'''2.1 在apps資料夾下新建應用： oauth'''
cd syl/apps
python ../manage.py startapp oauth # 切換到apps資料夾下執行建立命令

'''2.2 新增子路由： oauth/urls.py'''
from django.urls import path
from . import views
urlpatterns = [

]

'''2.3 在syl/settings.py中新增應用'''
INSTALLED_APPS = [
    'oauth.apps.OauthConfig'
 
,
]

'''2.4 在syl/urls.py主路由中新增'''
urlpatterns = [
    path('oauth/', include('oauth.urls')),
]

2.生成微博授權URL介面

1.1 新增子路由： oauth/urls.py

urlpatterns = [
    path('weibo/', views.WeiboUrl.as_view()), # /oauth/weibo/ 返回博登入地址
]

1.2 檢視函式: oauth/views.py

from urllib.parse import urlencode

from rest_framework.permissions import
 
 AllowAny
from rest_framework.response import Response
from rest_framework.views import APIView


# 生成前端跳轉到微博掃碼頁面的url
class WeiboUrl(APIView):
    '''
        生成微博的登陸頁面路由地址
        https://api.weibo.com/oauth2/authorize? # 微博oauth認證地址
        client_id=4152203033& # 註冊開發者id
        response_type=code&
        redirect_uri=http://127.0.0.1:8888/oauth/callback/ # 獲取code後將code回
        調給後端地址
    
 
'''
    # 自定義許可權類
    permission_classes = (AllowAny,)

    def post(self, request):
        url = 'https://api.weibo.com/oauth2/authorize?'  # 微博授權的url地址
        data = {
            'client_id': '3516473472',  # WEIBO_APP_KEY,
            'response_type': 'code',
            'redirect_uri': 'http://127.0.0.1:8888/oauth/callback/',  # VUE的回撥，微博後臺授權的回撥地址
        }
        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.測試生成微博售前URL介面

　　·測試介面獲取新浪微博地址

http://192.168.56.100:8888/oauth/weibo/

　　· 在瀏覽器訪問返回地址即可回到新浪掃碼介面

https://api.weibo.com/oauth2/authorize？client_id=3516473472&response_type=code&redirect_uri=http%3A%2F%2F127.0.0.1%3A8080%2Fweibo_callback
