**cat views.py**

def index(request):
        # return HttpResponse('Hello, world. You\'re at the polls index.')
        return render(request,'index.html')
    def login(request):
        if request.method == "POST":
            user = request.POST.get('username')
            password = request.POST.get('password')
            message='请检查填写内容!'
            print('------user:%s,password:%s------'%(user,password))
            if user.strip() and password:
                try:
                    u=models.User.objects.get(user=user)                 #u返回一个数据对象.获取数据对象的某一个属性字段值通过点的方式获取如:                 print('---数据库用户:%s,密码:%s,注册日期:%s'%(u.user,u.passwd,u.c_time))
                except Exception as f:
                    print(f)
                    message = '用户不存在!'
                    return render(request,'login/login.html',{'message':message})
                if u.passwd == password:
                    return redirect('/')
                else:
                    message = '密码不正确'
                    return render(request,'login/login.html',{'message':message})
            return render(request,'login/login.html',{'message':message})
        return render(request,'login/login.html')
    
    ################################################
    def register(request):
        return render(request,'login/register.html')
    def logout(request):
        return redirect("index.html")

**前端模板调用:** cat index.html

<!DOCTYPE html>
    <html>
    <head>
        <title>登陆</title>
    </head>
    <body> 
        <div  style = "margin:15％40％;" > 
           <h2>欢迎登录!</h2 >
            {% if message %}
            <div>{
        { message }}</div>
            {% endif %}
           <form  action = "/login/"  method ="post">
                {% csrf_token %}
                <label  for="id_username">用户名：</label><input  type="text" id ="id_username"  name="username" required/>
                <br>
                <label for= "id_password">密码:</label><input type="password" id="id_password" placeholder="密码" name="password" required>
                <br>
                <input type ="submit"  value ="登录">
                <a href="/register/" class="text-success " ><ins>新用户注册</ins></a>
            </form >
        </div>
    </body>
    </html>
