easyswoole、swoole如何用，怎么用easywechat？

示例：在App目录下创建Component，然后创建Request.php 去 继承 easywechat里用的SymfonyRequest类

<?php
namespace App\Component;
use Symfony\Component\HttpFoundation\Request as SymfonyRequest;
class Request extends SymfonyRequest
{
    /**
     * @param bool $asResource
     * @return string
     */
    public function getContent($asResource = false)
    {
        parent::getContent($asResource); // TODO: Change the autogenerated stub
        if (null == $this->content || false === $this->content) {
            $this->content = \Core\Http\Request::getInstance()->getBody()->__toString();
        }
        return $this->content;
    }
}

再创建个Wechat.php，我是为了方便管理，具体你们习惯放哪就放哪。

<?php
namespace App\Component;
use EasyWeChat\Foundation\Application;
class Wechat
{
    protected static $instance;
    protected $application;
    static function getInstance(){
        if(!isset(self::$instance)){
            self::$instance = new static();
        }
        return self::$instance;
    }
    public function __construct($config = null)
    {
        if(empty($config)){
            $config = \Conf\Config::getInstance()->getConf('wechat');
        }
        $application = new Application($config);
        $application->server->setRequest(\App\Component\Request::createFromGlobals());
        $this->application = $application;
    }
    public function getApplication(){
        return $this->application;
    }
}

然后创建个控制器，给预定义变量$_GET、$_POST等赋值，记得啊老铁，这是常驻内存，请求完毕记得清理这些预定义变量，建议在Controller的afterAction里去清理。

<?php
namespace App\Controller;
use fashop\Controller;
use EasyWeChat\Foundation\Application;
class Index extends Controller
{
    public function index()
    {
        $_GET    = isset( $request->getSwooleRequest()->get ) ? $request->getSwooleRequest()->get : [];
        $_POST   = isset( $request->getSwooleRequest()->post ) ? $request->getSwooleRequest()->post : [];
        $_COOKIE = isset( $request->getSwooleRequest()->cookie ) ? $request->getSwooleRequest()->cookie : [];
        $_FILES  = isset( $request->getSwooleRequest()->files ) ? $request->getSwooleRequest()->files : [];
        $server  = $request->getSwooleRequest()->server;
        $_SERVER = [];
        if( isset( $server ) ){
            foreach( $server as $key => $value ){
                $_SERVER[strtoupper( $key )] = $value;
            }
        }
        if(!isset($_GET['openid'])){
            $timestamp = $_GET['timestamp'];
            $nonce     = $_GET['nonce'];
            $token     = "hanwenbo";
            $signature = $_GET['signature'];
            $array     = [$timestamp, $nonce, $token];
            sort( $array );
            $tmpstr = implode( '', $array );
            $tmpstr = sha1( $tmpstr );
            if( $tmpstr == $signature ){
                $this->response()->write( $_GET['echostr'] );
                $this->response()->end();
            }
        }else{
            $app = new Application(\Conf\Config::getInstance()->getConf('wechat'));
            $server = $app->server;
            $server->setRequest(\App\Component\Request::createFromGlobals());
            $server->setMessageHandler(function($message){
                    switch ($message->MsgType) {
                    case 'event':
                        return '收到事件消息';
                    break;
                    case 'text':
                        return "收到了文字111";
                    break;
                    case 'image':
                        return '收到图片消息';
                    break;
                    case 'voice':
                        return '收到语音消息';
                    break;
                    case 'video':
                        return '收到视频消息';
                    break;
                    case 'location':
                        return '收到坐标消息';
                    break;
                    case 'link':
                        return '收到链接消息';
                    break;
                        // ... 其它消息
                    default:
                        return '收到其它消息';
                    break;
                    }
            });
            $response = $server->serve();
            $content = $response->getContent();
            $this->response()->write($content);
        }
    }
    public function onRequest( $actionName )
    {
        // TODO: Implement onRequest() method.
    }
