HttpResponse重定向子类HttpResponseRedirect使用演示

'''HttpResponse子类HttpResponseRedirect重定向
urls.py:
    url(r'^redirect1/$', views.redirect1),
    url(r'^redirect2/$', views.redirect2),

views.py:
# 重定向方法1
from django.http import HttpResponseRedirect
def redirect1(request):
    import time
    time.sleep(2)
    return HttpResponseRedirect('/redirect2/')

def redirect2(request):
    return HttpResponse('#########')

# 重定向方法2
from django.shortcuts import redirect
def redirect1(request):
    import time
    time.sleep(2)
    return redirect('/redirect2/')

def redirect2(request):
    return HttpResponse('#########')
'''

'''HttpResponse子类JsonResponse用于异步请求，返回json数据
HttpRequest对象方法：
is_ajax():如果是通过XMLHttpRequest发起的请求返回True

urls.py:
    url(r'^redirect1/$', views.redirect1),
    url(r'^redirect2/$', views.redirect2),

views.py:
from django.http import JsonResponse
def json_resp(request):
    if request.is_ajax():  # 判断是不是ajax请求
        jr = JsonResponse({})  # 接受一个JSON数据类型的对象
        return 

JsonResponse中__init__(self, data),其中data是一个json类型对象，Content-type为application/json
