Django 获取前端发送的头文件
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?
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。
