django 认证系统--3

WEB request中的认证

django使用sessions和middleware和reqeust对象联系在一起

它们通过给每一个reqeust请求添加一个request.user属性来代表当前用户。如果用户没有登录，那么request.user将是AnonymousUser的对象，如果登录了，那么就是User的对象

{% extends "base.html" %}

{% block content %}

{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}

{% if next %}
{% if user.is_authenticated %}
<p>Your account doesn't have access to this page. To proceed,
please login with an account that has access.</p>
{% else %}
<p>Please login to see this page.</p>
{% endif %}
{% endif %}

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

<tr>
<td>{{ form.username.label_tag }}</td>
<td>{{ form.username }}</td>
