- 利用协程特性以同步方式来编写异步代码，增强可读性。
- 将swoole的异步特性与传统框架的MVC相结合。
- 可以用作api也可以用作http server,rpc server.
- 目前实现了以redis为注册中心的服务化治理.
- 框架基本使用与传统框架基本一致，路由，控制器，服务层，数据层。
- 在异步调用的地方需要以yield关键词来触发协程切换
- 全异步协程调度，支持高并发
- 异步TCP，HTTP客户端
- 异步日志
- 异步文件读写
- 异步Mysql
- 异步Mysql事务处理
- 异步Redis
- 支持Mysql连接池,Redis连接池
- SOA服务化调用，内部封装完整的RPC通信，服务端采用异步Task处理后合并数据并返回。
- 异步TCP客户端支持并行、串行调用
- 支持EOF结束符协议、自定义网络通信协议，支持json化、php序列化包体，支持gzip。
- Twig、Doctrine支持视图、服务数据层
- 单元测试覆盖
use AsyncTcp;
$tcp = new AsyncTcp('127.0.0.1', 9501);
$tcp->setTimeout(2);
//串行发送
$res = (yield $tcp->call('hello server!'));
$res = (yield $tcp->call('hello server!'));
//并行发送数据包
$tcp->addCall('hello server1!');
$tcp->addCall('hello server2!');
$res = (yield $tcp->multiCall());- tcp客户端的数据包格式可在config/app.php中配置.
- protocol为buf时，是按包头+包体封装数据包的，包头为4个字节，存放包体的长度，解包时同样也是按包头+包体解包，所以服务端send数据时也要按同样规则封包。
- protocol为eof时，是按'\r\n'结束符封装数据包的，解包时同样也是按'\r\n'解包，所以服务端send数据时也要按'\r\n'结束符封装数据包。
- protocol为空的话，不封装数据包。在应答式响应中可以使用，否则会出现粘包现象。(框架内部封装的service为该模式)

//在框架层，调用servcie时，会抛出KernalEvent::SERVICE_CALL事件，你可以监听该事件，做数据上报处理，请以异步方式上报，例如：

class ServiceCallListener extends Listener
{
public function setMethod()
{
return 'onServiceCall';
}
public function onServiceCall(Event $event)
{
$data = $event->getProperty();
$cmd = $data['cmd'];
$calltime = $data['calltime'];
//上报监控平台
//do something
}
