django设置cookie

Posted 2020-12-10 aaronthon

两个例子：

使用模板

  from django.shortcuts import render, HttpResponse
  from rest_framework.views import APIView

class Order(APIView):
    def get(self, request, *args, **kwargs):
        response= render(request,‘login.html‘)
        response.set_cookie(‘username‘,‘xiaoming‘)  # 设置cookie
        return response

    def post(self, request, *args, **kwargs):
        ret = request.COOKIES[‘username‘]  # 获取cookie
        return HttpResponse(ret)

不使用模板

from django.shortcuts import render, HttpResponse
from rest_framework.views import APIView

class Order(APIView):
    
    def GET(self, request, *args, **kwargs):
        response = HttpResponse("ok")
        response.set_cookie("username","xiaoming")  # 设置cookie
        return response

    def GET(self, request, *args, **kwargs):
        ret = request.COOKIES["username"]  # 获取cookie
        res = request.COOKIES.get("username")  # 获取cookie
        return Httpresponse("success")

Django中操作Cookie

获取Cookie

request.COOKIES[‘key‘]
request.get_signed_cookie(key, default=RAISE_ERROR, salt=‘‘, max_age=None)

参数：

• default: 默认值
• salt: 加密盐
• max_age: 后台控制过期时间

设置Cookie

rep = HttpResponse(...)
rep ＝ render(request, ...)

rep.set_cookie(key,value,...)
rep.set_signed_cookie(key,value,salt=‘加密盐‘,...)

参数：

• key, 键
• value=‘‘, 值
• max_age=None, 超时时间
• expires=None, 超时时间(IE requires expires, so set it if hasn‘t been already.)
• path=‘/‘, Cookie生效的路径，/ 表示根路径，特殊的：根路径的cookie可以被任何url的页面访问
• domain=None, Cookie生效的域名
• secure=False, https传输
• httponly=False 只能http协议传输，无法被javascript获取（不是绝对，底层抓包可以获取到也可以被覆盖）

删除Cookie

def logout(request):
    rep = redirect("/login/")
    rep.delete_cookie("user")  # 删除用户浏览器上之前设置的usercookie值
    return rep

 结束！
