我有一个 login.html模板包含以下内容: 
<form method="post" action="{% url 'django.contrib.auth.views.login' %}">

如果我按如下方式更改 url 标记，那么我将得到另一个回溯。 
<form method="post" action="{% url django.contrib.auth.views.login %}">

有人可以告诉我出了什么问题吗？

请您参考如下方法:

您应该使用 URL 模式名称，而不是虚线 python 路径。

您还没有显示如何在 URL 中包含登录 View ，因此我们只能猜测正确的名称是什么，但可能是 'login' .

<form method="post" action="{% url 'login' %}">
