一、新建一个django项目bester：

django-admin startproject bester

 

二、在bester项目中建一个叫polls的应用程序：

cd bester/python3 manage.py startapp polls

 

三、给polls加一个叫index的函数：

　　cat polls/views.py

from django.shortcuts import renderfrom django.http import HttpResponsedef index(requst):    return HttpResponse("hello world ....")

 

 

四、polls增加路由：

　　1、在polls项目中加一个urls.py的文件、里面维护了一组url到视图的对应关系

touch polls/urls.py

　　2、polls/urls.py文件的内容如下：

from django.conf.urls import urlfrom .views import indexurlpatterns=[    url(r'^$',index),]

 

 

五、把polls/urls.py中的路由信息增加到项目的路由信息中去：

　　修改bester/urls.py 文件的内容如下：

"""bester URL ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see:    https://docs.djangoproject.com/en/1.11/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. Import the include() function: from django.conf.urls import url, include    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))"""from django.conf.urls import url,includefrom django.contrib import adminurlpatterns = [    url(r'^admin/', admin.site.urls),    url(r'^polls/',include('polls.urls'))]

 

 

六、启动http服务：

python3 manage.py runserverPerforming system checks...System check identified no issues (0 silenced).You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.Run 'python manage.py migrate' to apply them.November 13, 2017 - 08:43:42Django version 1.11.2, using settings 'bester.settings'Starting development server at http://127.0.0.1:8000/Quit the server with CONTROL-C.

 

 

七、从浏览器打开网页：

 

 

总结：

　　以上内容就是django官方文档中的第一个入门的例子了。
