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"})122020-07-25
