Django路由映射FBV 和 CBV

django中请求处理方式有2种：FBV(function base views) 和 CBV(class base views)，换言之就是一种用函数处理请求，一种用类处理请求。

FBV

# url.py
from django.conf.urls import url, include
from mytest import views
 
urlpatterns = [
    url(r‘^index/‘, views.index),
]

# views.py
from django.shortcuts import render
 
 
def index(req):
    if req.method == ‘POST‘:
        print(‘method is :‘ + req.method)
    elif req.method == ‘GET‘:
        print(‘method is :‘ + req.method)
    return render(req, ‘index.html‘)

View Code

CBV

# urls.py
from mytest import views
 
urlpatterns = [
    # url(r‘^index/‘, views.index),
    url(r‘^index/‘, views.Index.as_view()),
]

# views.py
from django.views import View

 
class Index(View):
    def get(self, req):
        print(‘method is :‘ + req.method)
        return render(req, ‘index.html‘)
 
    def post(self, req):
        print(‘method is :‘ + req.method)
        return render(req, ‘index.html‘)

# 注：类要继承 View ，类中函数名必须小写。
