blog应用urls中：

urlpatterns = [
re_path(‘member/‘,views.member,name=‘member‘)
]

views中：

def member(request):
    res={‘status‘:None,‘msg‘:None}
    if request.method == ‘POST‘:
        username=request.POST.get(‘username‘)
        pwd=request.POST.get(‘pwd‘)
        isLogin=Member.objects.filter(username=username,pwd=pwd).first()
        if isLogin:
            res[‘status‘]= 1
            res[‘msg‘]=‘登录成功!‘
        else:
            res[‘status‘] = 0
            res[‘msg‘] = ‘登录失败!请重新输入...‘

        return HttpResponse(json.dumps(res))

    print(res)
    return render(request,‘member.html‘)
