django views.py视图 获取用户请求相关信息以及请求头

请求的其他信息

用户发来请求时候，不仅发来数据，也把请求头也发过来

在views.py 怎么找请求数据？

request是一个对象，这个对象封装很多信息，可以先查这个对象的类

print(type(request))

from django.shortcuts import reverse
def index(request):
    v = reverse(‘author:index‘)
    print(v)
    print(type(request))

    # 找到这个类 导入这个类 <class ‘django.core.handlers.wsgi.WSGIRequest‘>
    from django.core.handlers.wsgi import WSGIRequest

    return HttpResponse("index")

去查看这个类代码

请求相关信息都放在这里，request.POST,request.GET 都是在这里提取出来

封装了所有用户请求信息

request.environ

from django.shortcuts import reverse
def index(request):
    v = reverse(‘author:index‘)
    print(v)
    print(type(request))

    # 找到这个类 导入这个类 <class ‘django.core.handlers.wsgi.WSGIRequest‘>
    from django.core.handlers.wsgi import WSGIRequest

    # 封装了所有用户请求信息
    print(request.environ)

    return HttpResponse("index")

常用的请求参数request.GETrequest.POSTrequest.COOKIES

拿到请求头，控制用户用什么终端访问的

    print(request.environ[‘HTTP_USER_AGENT‘])
    # Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36

显示访问网站以什么终端发来请求 (安卓,ios,pc端)还有作用不同终端访问这个网站时候，显示不同页面，比如手机的访问手机端页面，电脑端访问电脑端页面

通过请求头,分辨出不同终端 访问不同页面
