生成微博授权URL接口

1.创建apps/oauth模块进行oauth认证

1.1 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

1.2 添加子路由： oauth/urls.py

from django.urls import path
from . import views
urlpatterns = [
]

1.3 在syl/settings.py中添加应用

INSTALLED_APPS = [
	'oauth.apps.OauthConfig',
]

1.4 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

2.1 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
]

2.2 syl/settings.py 中配微博地址

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

2.3 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 = 'http://api.weibo.com/oauth2/authorize?'   # 微博授权的url地址
		data = {
			'client_id': '3516473472',   # settings.WEIBO_CLIENT_ID
			'response_type': 'code',
			'redirect_url': '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}})

//请求
https://api.weibo.com/oauth2/authorize?client_id=3516473472&redirect_uri=http://127.0.0.1:8888/oauth/callback/&response_type=code

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/
  
• 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=3516473472&response_type=code&redirect_uri=http%3A%2F%2F127.0.0.1%3A8080%2Fweibo_callback
