Real-time message push based on RPC service of ThinkPHP6 and Swoole
In recent years, with the rapid development of the Internet, real-time communication has become an important requirement for the development of many applications . Real-time message push is one of the most common and popular methods. This article will introduce how to use ThinkPHP6 and Swoole to implement a real-time message push service based on RPC (remote procedure call), and provide specific code examples.
composer create-project topthink/think tp6
composer require swoole/swoole
pecl install redis
Then add the following lines to your php. ini file:
extension=redis.so
config
directory under the root directory of the ThinkPHP6 project, create a new file rpc.php
, and add the following code in it: <?php return [ 'server' => [ // 服务监听的IP地址 'host' => '127.0.0.1', // 服务监听的端口号 'port' => 9501, // 异步任务的工作进程数量 'task_worker_num' => 4 ] ];
app
directory of the ThinkPHP6 project root directory, create a file named push
's new controller is used to handle the relevant logic of real-time message push. In this controller, we will use Swoole to create an RPC service and listen on the specified port. Add the following method in the push
controller:
<?php namespace appcontroller; use thinkRequest; class Push { /** * RPC服务入口方法 */ public function rpcServer(Request $request) { // 创建一个新的Swoole服务器对象 $server = new SwooleServer(config('rpc.server.host'), config('rpc.server.port')); // 设置异步任务的工作进程数量 $server->set(array('task_worker_num' => config('rpc.server.task_worker_num'))); // 监听连接事件 $server->on('connect', function ($server, $fd) { echo "客户端 " . $fd . " 已连接 "; }); // 监听数据接收事件 $server->on('receive', function ($server, $fd, $from_id, $data) { // 处理接收到的数据 $message = json_decode($data, true); // TODO: 消息推送逻辑 // 发送响应数据 $server->send($fd, '消息已成功接收'); }); // 监听关闭事件 $server->on('close', function ($server, $fd) { echo "客户端 " . $fd . " 已断开连接 "; }); // 启动RPC服务 $server->start(); } }
php think push/rpcServer
<?php /** * 向RPC服务发送消息 */ function sendMessage($message) { $client = new SwooleClient(SWOOLE_SOCK_TCP); // 连接到RPC服务端 if ($client->connect('127.0.0.1', 9501)) { // 发送消息 $client->send(json_encode($message)); // 接收响应 echo $client->recv(); // 关闭连接 $client->close(); } else { echo "无法连接到RPC服务 "; } } // 调用sendMessage方法发送消息 sendMessage(['content' => 'Hello']);
