使用 hyperf 已经有一段时间了，下面是一些常用的助手函数，分享一下~~~

<?php

use HyperfContractStdoutLoggerInterface;
use HyperfHttpServerContractResponseInterface;
use HyperfLoggerLoggerFactory;
use HyperfServerServerFactory;
use HyperfUtilsApplicationContext;
use PsrHttpMessageServerRequestInterface;
use SwooleWebsocketFrame;
use SwooleWebSocketServer as WebSocketServer;

/**
 * 容器实例
 */
if (!function_exists('container')) {
 function container()
 {
 return ApplicationContext::getContainer();
 }
}

/**
 * redis 客户端实例
 */
if (!function_exists('redis')) {
 function redis()
 {
 return container()->get(Redis::class);
 }
}

/**
 * server 实例 基于 swoole server
 */
if (!function_exists('server')) {
 function server()
 {
 return container()->get(ServerFactory::class)->getServer()->getServer();
 }
}

/**
 * websocket frame 实例
 */
if (!function_exists('frame')) {
 function frame()
 {
 return container()->get(Frame::class);
 }
}

/**
 * websocket 实例
 */
if (!function_exists('websocket')) {
 function websocket()
 {
 return container()->get(WebSocketServer::class);
 }
}

/**
 * 缓存实例 简单的缓存
 */
if (!function_exists('cache')) {
 function cache()
 {
 return container()->get(PsrSimpleCacheCacheInterface::class);
 }
}

/**
 * 控制台日志
 */
if (!function_exists('stdLog')) {
 function stdLog()
 {
 return container()->get(StdoutLoggerInterface::class);
 }
}

/**
 * 文件日志
 */
if (!function_exists('logger')) {
 function logger()
 {
 return container()->get(LoggerFactory::class)->make();
 }
}

/**
 *
 */
if (!function_exists('request')) {
 function request()
 {
 return container()->get(ServerRequestInterface::class);
 }
}

/**
 *

if (!function_exists('response')) {
 function response()
 {
 return container()->get(ResponseInterface::class);
 }
}
