urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^FBVTEST/', views.FBV_Test.as_view()),
]

from django.shortcuts import render,HttpResponse,redirect
from django.views import View

# Create your views here.

class FBV_Test(View):
    def  dispatch(self,request, *args, **kwargs):
      ret=super(FBV_Test,self).dispatch(request,*args,**kwargs)
      return ret

    def get(self,request):
        return HttpResponse('get')


    def post(self,request):
        return render(request,'login.html',locals())

<div class="container">
    <div class="row">
        <div class="col-md-4 col-md-offset-4">
            <form action="" method="post">
                <input type="submit">

 发送数据方式

 执行过程

 

执行views.LoginView.as_view()---》把requst传入View-----》执行dispatch函数（如果视图中有dispatch方法则覆盖）---》执行get方法--》返回给dispatch方法--》返回给url-->浏览器就可见了

url(r'^login/', views.LoginView.as_view()), #view(request)<=====》dispatch()<=====》self.get()
