如何使用

• 安装

  pip install djangowebsocket
  

• 更改 的内容asgi.py，如果您的项目名称是Project

  import os
  
  from django.core.asgi import get_asgi_application
  
  from djangowebsocket import get_ws_application
  from djangowebsocket import path, paths, middleware
  
  os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Project.settings')
  
  http_application = get_asgi_application()
  websocket_application = get_ws_application()
  
  # register your routers, About to support regular matching
  path('/path1/', ViewClass1)  # what is ViewClass, see below
  # or
  paths({
      '/path2/': ViewClass2,
      '/path3/': ViewClass3,
  })
  
  
  # register your middleware, it's sequential
  middleware(MiddlewareClass1)  # what is MiddlewareClass1, see below
  # or
  middlewares([MiddlewareClass2, MiddlewareClass3])
  
  
  async def branch(scope, receive, send):
      if scope.get('type') == 'websocket':
          await websocket_application(scope, receive, send)
      else:
          await http_application(scope, receive, send)
  
  
  application = branch
  

• 编写 ViewClass

  from djangowebsocket import BaseWebSocketView, Response
  
  
  class WebSocketView(BaseWebSocketView):
  
      def websocket(self, request):
          # Response's data can be str, dict, list, tuple, etc.
          return Response({'test': '123'})
  

• 编写中间件类

  from djangowebsocket import BaseMiddleware
  
  
  class MD(BaseMiddleware):
      def process_request(self, request):
          print(request.data)  # Preprocess request
          return request
  
      def process_response(self, request, response):
          response.set_data({'111': 222})  # Set data by set_data
          return response
  

• 请求有attr：

  QUERY  # params in path
  HEADER
  TYPE
  ASGI
  SCHEM
  SERVER
  CLIENT
  ROOT_PATH
  PATH
  RAW_PATH
  SUB_PROTOCOLS
