在oss/templates/accounts中添加login.html,register.html和welcome.html

login.html
<html lang="en"> <head><title>Account Login</title> </head> <body>{% if messages %} <ul>{% for message in messages %}<li>{{ message }}</li>{% endfor %} </ul> {% endif %}<form action="" method="post">{% csrf_token %}//防止用户重复非法登录<table border="0" cellpadding="0" >{{form.as_table}} </table><p> <a href="{%url "register_view"%}">注册</a> <a href="{%url "index"%}">返回首页</a> <input type="submit" value="登录"/></p></form> </body> </html>

Register.html

Welcome.html
<html lang="en"> <head><title>Welcome!</title> </head> <body><h2>{{w}}</h2>//调用login视图里的字典（key=w）<hr/> {% if messages %} <ul class="messages">{% for message in messages %}<li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>{% endfor %} </ul> {% endif %} {% if user.is_authenticated %}<a href="{% url "logout_view" %}">注销</a><a href="{% url "index_oss" %}">返回hrloo_oss主页</a> {% else %}<a href="{% url "login_view" %}">登陆</a> |<a href="{% url "register_view" %}">注册</a> {% endif %} </body> </html>
在oss/urls.py 中添加如下url
url(r'^accounts/login/$', 'oss.accounts.views.login_view', name='login_view'),
url(r'^accounts/logout$', 'oss.accounts.views.logout_view', name='logout_view'),
url(r'^accounts/register$', 'oss.accounts.views.register', name='register_view'),
现在启动web服务：python manage.py runserver 10.1.1.145:8000
访问url:http://10.1.1.145:8000/accounts/login 就可以看到登录界面，注册和登出操作访问相应url就可以实现。
