修改完之后,

python manage.py runserver 192.168.99.218:8080
http://192.168.99.218:8080/admin

可以使用

修改 ch0821www / urls.py

"""ch0821www URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.8/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import include, url
from django.contrib import admin
from mysite import views
urlpatterns = [
    url(r'^$', views.index),
    url(r'^(\d+)/(\w+)/$', views.index),
    url(r'^list/$',views.listing),
    url(r'^post/$',views.posting),
    url(r'^admin/', include(admin.site.urls)),
]

修改 header.html

    <nav class='navbar navbar-default'>
        <div class='container-fluid'>
            <div class='navbar-header'>

                    不吐不快

            </div>
            <ul class='nav navbar-nav'>
                <li class='active'><a href='/'>Home</a></li>
                <li><a href='/list'>浏览信息</a></li>  
                <li><a href='/post'>张贴信息(仅窗体)</a></li>
                <li><a href='/post2db'>张贴信息</a></li>
                <li><a href='/contact'>联络管理员</a></li>
                <li><a href='/admin'>后台管理</a></li>  
            </ul>
        </div>
