Django框架的使用教程路由请求响应的方法

# 主路由
from django.conf.urls import url,include
from django.contrib import admin
import django_test.urls

urlpatterns = [
  url(r'^admin/', admin.site.urls),
  url(r'^users/',include(django_test.urls ,namespace='users'))
]

urlpatterns = [
  # 这边定义子应用的路由
  url(r'^index/$',views.index,name='index'),
  url(r'^show/$',views.show,name='show'),
  url(r'^parameter/([a-z]+)/(\d{4})$',views.parameter,name='parameter'),
]

# name,和age参数位置调换会影响下面的输出结果
def parameter(request,name, age):

  print('age=%s'%age)
  print('name=%s' % name)
  return HttpResponse('OK')

urlpatterns = [
  # 这边定义子应用的路由
  url(r'^index/$',views.index,name='index'),
  url(r'^show/$',views.show,name='show'),
  url(r'^parameter/(?P<name>[a-z]+)/(?P<age>\d{4})$',views.parameter,name='parameter'),
]

# age 和name位置改变值不变
def parameter(request,age, name):

  print('age=%s'%age)
  print('name=%s' % name)
  return HttpResponse('OK')

url(r'^qust/$',views.qust),

def qust(request):
  a = request.GET.get('a')
  b = request.GET.get('b')
  alist = request.GET.getlist('a')
  print(a) # 3
  print(b) # 2
  print(alist) # ['1', '3']
  return HttpResponse('OK')

url(r'^get_form/$', views.get_form)

def get_form(request):
  name = request.POST.get('name')
  age = request.POST.get('age')
  alist = request.POST.getlist('name')
  print(name)
  print(age)
  print(alist)
  return HttpResponse('OK')

url(r'^get_body_json/$', views.get_body_json),

def get_body_json(request):
  json_str = request.body
  json_str = json_str.decode() # python3.6 无需执行此步
  req_data = json.loads(json_str)
  print(req_data['a'])
  print(req_data['b'])
  return HttpResponse('OK')

url(r'^get_head/$', views.get_head)

def get_head(request):
  print(request.META['CONTENT_TYPE'])
  return HttpResponse('OK')

# content:表示返回的内容
# status_code:返回的HTTP响应状态码
# content_type: 指定返回数据的MIME类型
from django_http import HttpResponse

def index(request):
  return HttpResponse('欢迎来到Gaidy博客', status=202)

from django.http import JsonResponse

def index(request):
  return JsonResponse({'name': 'gaidy', 'age': '25'})

from django.shortcuts import redirect

# django_test是路由的空间命名
def show(request):
  # 重定向
  return redirect(reverse('django_test:index'))
