python-django-请求响应对象
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：

def print_resp(request): now = datetime.now() html = """ <html> <head> <style type="text/css"> body{{color:red;}} </style> </head> <body> now:{0} </body> </html> """.format(now) return HttpResponse(html,content_type='text/plain')
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)
通过二进制流读取图片并进行展示到页面里面
结果：
展示表格：
