Using RPC services built with ThinkPHP6 and Swoole to implement high-availability task queues
[Introduction]
Task queues play an important role in modern development. It can separate time-consuming tasks from the main process, improve the response speed of the system, and ensure the reliability and high availability of tasks when the system fails or the network is interrupted. In this article, we will introduce how to use ThinkPHP6 and Swoole to build a highly available task queue to implement asynchronous task processing and provide RPC services for task queue management.
[Environment preparation]
Before we start, we need to prepare some development environments, including:
[Project construction]
composer create-project topthink/think hello-think
"require": { "swoole/swoole": "4.6.7", "swoole/ide-helper": "4.6.7" }
Then execute thecomposer update
command to install dependencies.
return [ 'rpc' => [ 'listen_ip' => '0.0.0.0', 'listen_port' => 9501, 'worker_num' => 4, 'task_worker_num' => 4, ], 'task' => [ 'task_ip' => '127.0.0.1', 'task_port' => 9502, ], 'timer' => [ 'interval' => 1000, ], ];
namespace apppcserver; use SwooleServer; use thinkRpcServer; use think acadeConfig; class TaskServer { protected $server; public function start() { $this->server = new Server(Config::get('swoole.rpc.listen_ip'), Config::get('swoole.rpc.listen_port')); $rpcServer = new RpcServer($this->server); $rpcServer->classMap([ 'apppcserviceTaskService', ]); $rpcServer->start(); } }
namespace apppcservice; class TaskService { public function addTask($data) { // 处理添加任务的逻辑,将任务添加到任务队列中 } public function getTask($id) { // 处理获取任务的逻辑,从任务队列中获取相关任务信息 } // 其他RPC方法... }
[Implementation of task queue]
CREATE TABLE `task` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `task_name` varchar(255) DEFAULT NULL, `task_data` text, `task_status` tinyint(1) DEFAULT NULL, `create_time` int(11) DEFAULT NULL, `update_time` int(11) DEFAULT NULL, PRIMARY KEY (`id`), KEY `task_status` (`task_status`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
namespace appmodel; use thinkModel; class Task extends Model { protected $autoWriteTimestamp = true; protected $dateFormat = 'Y-m-d H:i:s'; }
namespace appservice; use appmodelTask; class TaskService { public function addTask($data) { $task = new Task; $task->task_name = $data['task_name']; $task->task_data = $data['task_data']; $task->task_status = 0; $task->save(); // TODO: 将任务添加到任务队列中 } public function getTask($id) { return Task::find($id); } // 其他任务处理逻辑... }
[Implementation of scheduled tasks]
namespace appservice; use appmodelTask; use SwooleTimer; class TimerService { public function start() { Timer::tick(config('swoole.timer.interval'), function() { // TODO: 定时检查任务队列,处理待执行的任务 }); } // 其他定时任务处理逻辑... }
public function start() { $this->server = new Server(Config::get('swoole.rpc.listen_ip'), Config::get('swoole.rpc.listen_port')); $rpcServer = new RpcServer($this->server); $rpcServer->classMap([ 'apppcserviceTaskService', ]); $timerService = new TimerService(); $timerService->start(); $rpcServer->start(); }
[Start RPC service and task queue]
Execute the following command in the project root directory to start the RPC service and task queue.
php think swoole:rpc start
[RPC call example]
Example of using RPC to call task queue in an application.
class Index extends Controller { public function index() { $taskService = new pppcserviceTaskService(); $taskService->addTask([ 'task_name' => '任务名称', 'task_data' => '任务数据', ]); } }
[Summary]
By using ThinkPHP6 and Swoole extension, we can build a highly available task queue system. Use RPC services to manage task queues, provide interfaces for adding tasks and obtaining tasks, realize asynchronous processing of tasks, and improve the response speed and availability of the system. At the same time, using Swoole's scheduled task function, you can check the task queue regularly and process pending tasks in a timely manner. Such a system architecture can not only improve the system's processing capabilities, but also has good scalability and fault tolerance.
