include 使用 method htm elf ext 小寫 logs test
django中請求處理方式有2種:FBV 和 CBV
一、FBV
FBV(function-based views) 就是在視圖裏使用函數處理請求。
urls.py
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.py
from django.shortcuts importrender def index(request): if request.method == ‘POST‘: print(‘method is :‘ + request.method) elif request.method == ‘GET‘: print(‘method is :‘ + request.method) return render(request, ‘index.html‘)
註意此處定義的是函數【def index(request):】
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>
上面就是FBV的使用。
二、CBV
CBV(class-based views) 就是在視圖裏使用類處理請求。
將上述代碼中的urls.py 修改為如下:
from mytest import views urlpatterns = [ # url(r‘^index/‘, views.index), url(r‘^index/‘, views.Index.as_view()), ]
註:url(r‘^index/‘, views.Index.as_view()), 是固定用法。
將上述代碼中的views.py 修改為如下:
from django.views import View class Index(View): def get(self, request): print(‘method is :‘ + req.method) return render(request, ‘index.html‘) def post(self, request): print(‘method is :‘ + request.method) return render(request, ‘index.html‘)
註:類要繼承 View ,類中函數名必須小寫。
