Swoole异步投递task任务
- 【使用场景】
- 【使用须知】
- 【示例】
- - ws_server.php
  - index.html
php swoole4 执行异步任务(Task)
- WS.php写服务端代码
- chat.html写客户端代码
- 测试效果
- - 1、分别打开服务端和客户端
  - 2、发送信息测试
  - 3、等待10秒后

Swoole异步投递task任务

实现实例前提：需要安装swoole 在这里插入图片描述

【使用场景】

Swoole的 task 模块可以用来做一些异步的慢速任务、耗时场景。

如webim中发广播，发送邮件等，把这些任务丢给task进程之后，worker进程可以继续处理新的数据请求，任务完成后会异步通知worker进程告诉它此任务已经完成。

此外利用 task 还可以实现PHP的数据库连接池，异步队列等。

【使用须知】

必须设置Task进程数：task_worker_num

投递一个异步任务到task_worker池中：Server->task

必须注册onTask、onFinish2个事件回调函数。

【示例】

以创建一个WebSocket服务异步投递任务为例：

ws_server.php
