项目背景:
最近由于公司的业务需求,需要用到聊天功能。而且有比较多的个性化需求需要定制。之前使用别人的聊天组件是基于微擎的。如果要移植到普通的H5在逻辑修改还有定制上存在比较多的困难。为此只能克服困难,自己搭建一个吧
什么是Workerman?
Workerman是一款 开源 高性能异步 PHP socket即时通讯框架 。支持高并发,超高稳定性,被广泛的用于手机app、移动通讯,微信小程序,手游服务端、网络游戏、PHP聊天室、硬件通讯、智能家居、车联网、物联网等领域的开发。 支持TCP长连接,支持Websocket、HTTP等协议,支持自定义协议。拥有异步Mysql、异步Redis、异步Http、MQTT物联网客户端、异步消息队列等众多高性能组件。
开始实战吧!
1.第一步我们先把workerman里需要用到的扩展composer下来吧
1
2
3
|
"workerman/gateway-worker": "^3.0",
"workerman/gatewayclient": "^3.0",
"workerman/workerman": "^3.5",
|
2.第二步我们到官方网站把demo全部下载下来,然后放到我们项目中的目录
图片中我就把整个项目都放在了HTTP/Controller/Workerman中。
3.第三步我们需要把把以下3个文件的引用部分修改为以下。不然会报路径错误
start_businessworker,start_gateway,start_register
1
|
require_once
__DIR__ .
'/../../../../../vendor/autoload.php'
;
|
4.修改完成后我们就可以在liunx直接运行对应的启动文件
1
|
php start.php start -d
|
如果你是在window下就双击start_for_win.bat运行
5.运行成功后,你就应该可以看到以下的界面
到此我们搭建基于workerman的通信环境就已经完成。接下来我们就可以根据自己的项目需求进行开发。在此向大家重点说明。我们所有的聊天是逻辑都在目录中的Events.php进行修改。

下面我给大家贴一下我编写的部分份代码。
