django中請求處理方式有2種:FBV 和 CBVhtml
FBV(function base views) 就是在視圖裏使用函數處理請求。python
看代碼:django
urls.py函數
from django.conf.urls import url, include # from django.contrib import admin from mytest import views urlpatterns = [ # url(r‘^admin/‘, admin.site.urls), url(r‘^index/‘, views.index), ]
views.pypost
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‘)
注意此處定義的是函數【def index(req):】url
index.htmlspa
<!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>
上面就是FBV的使用。orm
CBV(class base views) 就是在視圖裏使用類處理請求。htm
將上述代碼中的urls.py 修改成以下:blog
from mytest import views urlpatterns = [ # url(r‘^index/‘, views.index), url(r‘^index/‘, views.Index.as_view()), ]
注:url(r‘^index/‘, views.Index.as_view()), 是固定用法。
將上述代碼中的views.py 修改成以下:
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‘)
注:類要繼承 View ,類中函數名必須小寫。
兩種方式沒有優劣,均可以使用。
標籤:base text onf div spa 2種 inpu site .py
