Sanic框架基于类的视图用法示例

from sanic import Sanic
from sanic.views import HTTPMethodView
from sanic.response import text
class SanicView(HTTPMethodView):
  def get(self,request):
    return text("it is get")
  def post(self,request):
    return text("it is post")
  def put(self,request):
    return text("it is put")
  def patch(self,request):
    return text("it is patch")
  def delete(self,request):
    return text("it is delete")
app = Sanic()
app.add_route(SanicView.as_view(),"/method_view")
if __name__ == "__main__":
  app.run()

class SanicView(HTTPMethodView):
  async def get(self,request):
    return text("it is get")
app.add_route(SanicView.as_view(),"/method_view")

class SanicView(HTTPMethodView):
  async def get(self,request,name):
    return text("it is get and name is {}".format(name))
app.add_route(SanicView.as_view(),"/<name>")

def decorator(func):
  async def wrapper(request,*args,**kwargs):
    print("有装饰器")
    response = await func(request,*args,**kwargs)
    return response
  return wrapper
class SanicView(HTTPMethodView):
  decorators = [decorator]
  async def get(self,request):
    return text("it is ok!")
app.add_route(SanicView.as_view(),"/method_view")

from sanic.response import redirect
@app.route("/")
async def home(request):
  url = app.url_for("SanicView")
  return redirect(url)
class SanicView(HTTPMethodView):
  async def get(self,request):
    return text("it is get")
app.add_route(SanicView.as_view(),"/method_view")

from sanic.views import CompositionView
async def handle_get(request):
  return text("it is get")
view = CompositionView()
view.add(["GET"],handle_get)
view.add(["POST","PUT"],lambda request: text("it is post or put"))
app.add_route(view,"/composition_view")
