用户请求终端的信息：

包括使用的ip地址，浏览器类型等

cookie：

测试测试；

def print_request(request):

    print(request)

    print("!!!!!!!!!!!!!!!!")

    ip = request.META['REMOTE_ADDR']

    print(ip)

    #用户浏览器的信息，终端信息

    user_agent = request.META['HTTP_USER_AGENT']

    print(user_agent)

    print(dir(request))

    return HttpResponse()

urls.py如下：

url(r'print/request',views.print_request,name='print_request'),

结果：

<WSGIRequest: GET '/print/request'>

通过content——type进行指定返回的响应对象
def print_json(request):

    user_info = {

        'username':'张三',

        'age':50

    }

    import json

    user_info = json.dumps(user_info)

    return HttpResponse(user_info,content_type='application/json')

虽然python中的字典是和json有点相似，但是要以json的格式 进行输出是要

使用转换函数，json.dumps进行转换再输出的

　　

更加快捷的响应json：

def print_json(request):

    user_info = {

        'username':'张三',

        'age':50

    }

    return JsonResponse(user_info)

直接响应，因为里面封装了一个转换格式的函数，并且继承了httpresponse

两个的区别是：

一个是需要对象进行给与，statud_code 是resp的一个对象属性，通过对象使用
def print_resp_attr(request):

    # return HttpResponse('eee',status=209)

    resp = HttpResponse('打印响应对象',status=404)

    #重新设置HTTP的转台码

    resp.status_code=203

    print(resp.status_code)
