五个接口最终版源码解析
#url(r'^authors/(?P<pk>\d+)/', views.AuthorsView.as_view({"get":"retrieve","delete":"destroy","put":"update"})),
#url(r'^authors/$', ViewSetMixin.as_view({"get":"retrieve","delete":"destroy","put":"update"})),
#url(r'^authors/$', ViewSetMixin.view),
一旦用户访问,get访问authors/1：
ViewSetMixin.view(reqeust):
for method, action in actions.items(): # {"get":"retrieve","delete":"destroy","put":"update"}
handler = getattr(self, action) # handler===self.retrieve handler=== destroy handler===update
setattr(self, method, handler) # self.get=self.retrieve self.delete=self.destroy self.put=self.update
return self.dispatch(request, *args, **kwargs)
#
APIView.dispatch(request):
handler = getattr(self, request.method.lower()) # self.retrieve
response = handler(request, *args, **kwargs)
# def retrieve(self.request):
` # return .....
return response
