Question

我试图在我的页面上创建注销功能。但每次我点击指向注销网址的链接时，都会收到此递归错误。

以下是代码，用于显示内容和用户登录时的注销功能。否则显示登录表单。

查看方法

def login(request):

   username = request.POST.get('username')
   password = request.POST.get('password')

   user = authenticate(username=username, password=password)

   context = {

   }

   if user is not None:
       print('Correct user'   
   else:
       print('Wrong user')

       return render(request, 'index.html', context)

def logout(request):
    print('logged out')
    logout(request)

    return redirect('index')

URL

urlpatterns = [
            url(r'^$', views.index, name='index'),         

            url(r'^login/$', views.login, name='login'), 

            url(r'^logout/$', views.logout, name='logout'),
]

的index.html

    {% if user %}
        <h3>Hello {{user.username}}</h3>
        <a href="{% url 'crowd:logout' %}">Logout</a>
    {% else %}
        <form action="{% url 'crowd:login' %}" method='post'>
        {% csrf_token %}
            <input class='logintext' type='text' placeholder='Username' name='username'>
            <input class='logintext' type='password' placeholder='Password' name='password'><br>
            <input class='loginbutton' type='submit' value='Login'>
            <a class='loginforgotpassword' href="{% url 'crowd:register' %}"> Forgot password?</a>
            <a class='loginregister' href="{% url 'crowd:register' %}"> Register</a>
        </form>
    {% endif%}

控制台错误：

  File "C:\Users\Rasmus\workspace\Crowd\src\Cr\views.py", line 48, in logout
    logout(request)
  File "C:\Users\Rasmus\workspace\Crowd\src\Cr\views.py", line 48, in logout

请更改退出视图的名称。

错误在于：

def logout(request):
    print('logged out')
    logout(request)

    return redirect('index')

您的视图名称是带有请求参数的注销。因此，当您在视图中调用logout（request）时，它会调用您的注销视图而不是Django的注销功能。这导致了递归。

注销时请求的最大递归深度超过（请求）
