Django 如何获取前端发送的头文件详解（推荐）_Python

Django里面，我们知道可以在函数里面里面通过参数获取前端发来的数据。
比如可以通过request获取各种form的值啊，cookie啊等等。

									def index(reqeust):

									 # 获取当前已经登录的用户

									 v = reqeust.COOKIES.get('username111')

									 return render(reqeust,'index.html',{'current_user': v})

这些方法是Django把一些常用的数据已经替我们封装好了，因此可以直接使用。但是这些方法并不全，比如我刷新一个页面，这个请求的头文件里面，包含了一堆关于客户端的信息，如何获取所有的信息呢？

Django 如何获取前端发送的头文件详解（推荐）

我们可以通过request.environ来获取

首先需要导入一个类，如果忘记了这个类的名字，可以直接print(type(request))来获取。

<class 'django.core.handlers.wsgi.WSGIRequest'>

environ本质是个字典格式，因此可以直接print(k,v)获取所有的key和value，也可以通过对应的key来输出value

									def tpl1(request):

									 from django.core.handlers.wsgi import WSGIRequest

									 print(type(request))

									 print(request.environ)

									 for k,v in request.environ.items():

									 print(k,v)

									 print(request.environ['HTTP_USER_AGENT'])

									 user_list = [1, 2, 3, 43]

									 return render(request, 'tpl1.html', {'u': user_list})

输出结果：

注意最后的那个输出结果HTTP_USER_AGENT, 这个是客户端的信息，我们可以根据这个做判断，然后返回不同的结果，比如手机版和PC版返回的显示排版不同。
