django中请求处理方式有2种:FBV 和 CBV
一、FBV
FBV(function base views) 就是在视图里使用函数处理请求。
看代码:
urls.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‘)
注意此处定义的是函数【def index(req):】
index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>index</title> </head> <body> <form action="" method="post"> <input type="text" name="A" /> <input type="submit" name="b" value="提交" /> </form> </body> </html>
二、CBV
CBV(class base views) 就是在视图里使用类处理请求。
将上述代码中的urls.py 修改为如下:
from mytest import views urlpatterns = [ url(r‘^index/‘, views.Index.as_view()), ]
注:url(r‘^index/‘, views.Index.as_view()), 是固定用法。
将上述代码中的views.py 修改为如下:
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‘)
