django中請(qǐng)求處理方式有2種:FBV 和 CBV
FBV
FBV(function base views) 就是在視圖里使用函數(shù)處理請(qǐng)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 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(shù)【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>
上面就是FBV的使用。
二、CBV
CBV(class base views) 就是在視圖里使用類處理請(qǐng)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()),
]
注: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, 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(shù)名必須小寫
兩種方式?jīng)]有優(yōu)劣,都可以使用。
