# 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/("htmlcode">

# 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')


查询字符串(传递参数)
注意:查询字符串不区分请求方式，即假使客户端进行POST方式的请求，依然可以通过request.GET获取请求中的查询字符串数据。
子路由


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


视图函数


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')


运行(后面在加)

请求体(传递参数) 
表单类
路由设置


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


视图函数


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')


运行


非表单类
路由


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


视图


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')


运行

请求头(传递参数)
可以通过request.META属性获取请求头headers的数据
路由


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


视图函数


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


运行

常见的请求头
CONTENT_LENGTH – The length of the request body (as a string).
CONTENT_TYPE – The MIME type of the request body.
HTTP_ACCEPT – Acceptable content types for the response.
HTTP_ACCEPT_ENCODING – Acceptable encodings for the response.
HTTP_ACCEPT_LANGUAGE – Acceptable languages for the response.
HTTP_HOST – The HTTP Host header sent by the client.
HTTP_REFERER – The referring page, if any.
HTTP_USER_AGENT – The client's user-agent string.
QUERY_STRING – The query string, as a single (unparsed) string.
REMOTE_ADDR – The IP address of the client.
REMOTE_HOST – The hostname of the client.
REMOTE_USER – The user authenticated by the Web server, if any.
REQUEST_METHOD – A string such as  "GET" or  "POST" .
SERVER_NAME – The hostname of the server.
SERVER_PORT – The port of the server (as a string).
响应

  
 HttpResponse提供一系列子类
  
HttpResponseRedirect 301
  
HttpResponsePermanentRedirect 302
  
HttpResponseNotModified 304
  
HttpResponseBadRequest 400
  
HttpResponseNotFound 404
  
HttpResponseForbidden 403
  
HttpResponseNotAllowed 405
  
HttpResponseGone 410
  
HttpResponseServerError 500

案例 # HttpResponse(content=响应体,content_type=响应数据类型,status=状态码)


# 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)


JsonResponse(返回的json数据)


from django.http import JsonResponse

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


运行结果

redirect重定向


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'))
