五、主要技术介绍：
Django框架介绍：
Django是高水准的Python编程语言驱动的一个开源模型．视图，控制器风格的Web应用程序框架，它起源于开源社区。使用这种架构，程序员可以方便、快捷地创建高品质、易维护、数据库驱动的应用程序。这也正是OpenStack的Horizon组件采用这种架构进行设计的主要原因。另外，在Dj ango框架中，还包含许多功能强大的第三方插件，使得Django具有较强的可扩展性。Django 项目源自一个在线新闻 Web 站点，于 2005 年以开源的形式被释放出来。Django 框架的核心组件有：
用于创建模型的对象关系映射；
为最终用户设计较好的管理界面；
URL 设计；
设计者友好的模板语言；
缓存系统。
Django(发音：[`dʒæŋɡəʊ]) 是用python语言写的开源web开发框架(open source web framework)，它鼓励快速开发,并遵循MVC设计。Django遵守BSD版权，初次发布于2005年7月, 并于2008年9月发布了第一个正式版本1.0 。
Django 根据比利时的爵士音乐家Django Reinhardt命名，他是一个吉普赛人，主要以演奏吉它为主，还演奏过小提琴等。
由于Django在近年来的迅速发展，应用越来越广泛，被著名IT开发杂志SD Times评选为2013 SD Times 100，位列“API、库和框架”分类第6位，被认为是该领域的佼佼者。
1.9 Django架构设计：
Django已经成为web开发者的首选框架，是一个遵循 MVC 设计模式的框架。MVC是Model、View、Controller三个单词的简写，分别代表模型、视图、控制器。Django其实也是一个MTV 的设计模式。MTV是Model、Template、View三个单词的简写，分别代表模型、模版、视图。但是在Django中，控制器接受用户输入的部分由框架自行处理，所以 Django 里更关注的是模型（Model）、模板(Template)和视图（Views），称为 MTV模式。它们各自的职责如下：
| 层次 | 职责 |
| 模型（Model），即数据存取层 | 处理与数据相关的所有事务： 如何存取、如何验证有效性、包含哪些行为以及数据之间的关系等。 |
| 模板(Template)，即表现层 | 处理与表现相关的决定： 如何在页面或其他类型文档中进行显示。 |
| 视图（View），即业务逻辑层 | 存取模型及调取恰当模板的相关逻辑。模型与模板的桥梁。 |
从以上表述可以看出Django 视图不处理用户输入，而仅仅决定要展现哪些数据给用户，而Django 模板 仅仅决定如何展现Django视图指定的数据。或者说, Django将MVC中的视图进一步分解为 Django视图 和 Django模板两个部分，分别决定 “展现哪些数据” 和 “如何展现”，使得Django的模板可以根据需要随时替换，而不仅仅限制于内置的模板。
至于MVC控制器部分，由Django框架的URLconf来实现。URLconf机制是使用正则表达式匹配URL，然后调用合适的Python函数。URLconf对于URL的规则没有任何限制，你完全可以设计成任意的URL风格，不管是传统的，RESTful的，或者是另类的。框架把控制层给封装了，无非与数据交互这层都是数据库表的读,写,删除,更新的操作。在写程序的时候，只要调用相应的方法就行了，感觉很方便。程序员把控制层东西交给Django自动完成了。 只需要编写非常少的代码完成很多的事情。所以，它比MVC框架考虑的问题要深一步，因为我们程序员大都在写控制层的程序。这个工作交给了框架，仅需写很少的调用代码，大大提高了工作效率。
1.10 Django工作机制：
1.用manage .py runserver 启动Django服务器时就载入了在同一目录下的settings .py。该文件包含了项目中的配置信息，如前面讲的URLConf等，其中最重要的配置就是ROOT_URLCONF，它告诉Django哪个Python模块应该用作本站的URLConf，默认的是urls .py
2.当访问url的时候，Django会根据ROOT_URLCONF的设置来装载URLConf。
3.然后按顺序逐个匹配URLConf里的URLpatterns。如果找到则会调用相关联的视图函数，并把HttpRequest对象作为第一个参数(通常是request)
4.最后该view函数负责返回一个HttpResponse对象。
