一、Composer安装Symfony

  上一篇分析Symfony2框架源码,探究Symfony2如何完成一个请求的前半部分,前半部分可以理解为Symfony2框架为处理请求做准备工作,包括container生成、缓存、bundls初始化等一些列准备工作(Symfony2源码分析——启动过程1)。而这一篇讲的是Symfony2如何根据请求的数据生成Response对象,向客户端返回响应数据。

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。

Composer安装Symfony方法在前面的文章《Symfony之十分钟入门》有介绍

  在分析前需要了解Symfony2的事件驱动机制:Symfony2事件驱动。

二、Symfony Installer安装Symfony

  言归正传,Symfony2请求的工作流程其实是Symfony2内核的事件驱动完成的,下面是Symfony2框架定义好的内核事件:

这里来着重介绍第二种Symfony Installer安装Symfony的方法

1.安装Symfony Installer

final class KernelEvents
{
    /**
     * The REQUEST event occurs at the very beginning of request
     * dispatching

     * This event allows you to create a response for a request before any
     * other code in the framework is executed. The event listener method
     * receives a SymfonyComponentHttpKernelEventGetResponseEvent

    const REQUEST = 'kernel.request';

    /**
     * The EXCEPTION event occurs when an uncaught exception appears
     *

    const CONTROLLER = 'kernel.controller';

    /**

    const RESPONSE = 'kernel.response';

    /**
     * The TERMINATE event occurs once a response was sent

     *
     * @var string
     */
    const TERMINATE = 'kernel.terminate';

    /**
     * The FINISH_REQUEST event occurs when a response was generated for a request.
     *
     * This event allows you to reset the global and environmental state of
     * the application, when it was changed during the request.
     *
     * @var string
     */
    const FINISH_REQUEST = 'kernel.finish_request';
