在 retuen render 时后面括号打错

正确：

return render(request,"login.html",{"msg":"用户名或密码错误"})

class LoinView(View):
    def get(self, request, *args, **kwargs):
        return render(request,"login.html")

    def post(self, request, *args, **kwargs):
        user_name = request.POST.get("username","")
        passwoed = request.POST.get("password","")

        #通过用户名和密码查询用户是否存在
        user = authenticate(username=user_name, passwoed=passwoed)

        if user is not None:
            # user不为空，表示已经查询到用户
            login(request,user)
            # 登录成功之后，跳转
            return render(request,"index.html")
        else:
            #user为空，表示没有查询到用户
            return render(request,"login.html",{"msg":"用户名或密码错误"})
