[django]session设置与获取原理

admin登录

情况1: 登录后会产生一个sessionid

情况2: 自定义设置了key后,会多一个sessionid, 登录后会替换为登录后的sessionid的key值

        if username == "maotai" and password == "123456":
            request.session['name'] = "maotai-session" #定义一个session key
            request.session['name2'] = "maotai2-session"#定义一个session key

自定义sessionid

def login(request):
    if request.method == "POST":
        username = request.POST.get("username")
        password = request.POST.get("password")
        if username == "maotai" and password == "123456":
            request.session['name'] = "maotai-session" #定义一个session key
            request.session['name2'] = "maotai2-session"#定义一个session key

            name = request.session.get("name", "") # 获取一个session key
            name2 = request.session.get("name2", "")
            # return redirect("/")
            return render(request, "index.html", {"name": name, "name2": name2}) #将session key返回到前端
        else:
            return render(request, "login.html")
    elif request.method == "GET":
        return render(request, "login.html")

获取sessionid

request.session.get("name", "") # 获取一个session key   获取到的应该是下面的_session里的结果
