  • Django学习(1)一首情诗

      Django是Python中Web开发的最有代表性的框架之一。本文将简单介绍如何入门Django开发。
      首先确保你的linux系统已安装django模块。打开Python3,利用以下命令可找到django所在目录:

    >>> import django
    >>> print(django.__path__)

      笔者显示的是:

    ['/usr/lib/python3/dist-packages/django']

      接下来开始django开发!首先切换到django目录,新建poem项目:

    django-admin.py startproject poem

      输入tree poem,查看poem项目的树结构:

    poem项目的树结构

      在urls.py的urlpatterns列表中添加:

    url(r'^$', 'poem.views.output'),
    

      在/poem/poem文件夹下,创建views.py文件,输入代码:

    from django.http import HttpResponse
    
    def output(request):
       title = "<h1>When You Are Old</h1>"
       author = "<h2>William Butler Yeats</h2>"
       content = """
             When you are old and grey and full of sleep,<br/>
             And nodding by the fire, take down this book,<br/>
             And slowly read, and dream of the soft look<br/>
             Your eyes had once, and of their shadows deep;<br/>
             How many loved your moments of glad grace,<br/>
             And loved your beauty with love false or true,<br/>
             But one man loved the pilgrim soul in you,<br/>
             And loved the sorrows of your changing face;<br/>
             And bending down beside the glowing bars,<br/>
             Murmur, a little sadly, how love fled<br/>
             And paced upon the mountains overhead<br/>
             And hid his face amid a crowd of stars.<br/>
             """
       return HttpResponse([title, author, content])

      进入poem文件夹,输入命令:

    python3 manage.py runserver 8000

      打开浏览器,输入localhost:8000,页面如下图:

      这样我们就完成了一个简单的django项目的开发。期待下期分享~~
