一.服务端的实现(使用开源Gateway项目部署在linux)
下载此项目代码Gitee 但是此项目缺少了3个文件:
start_register.php
start_gateway.php
start_businessworker.php
从此项目中下载demo获得这三个文件放入对应目录: Gateway手册
将项目部署在linux服务器中, 然后服务端入口代码如下, 其余文件可以不用看

}
二.Windows客户端的实现(使用workerman部署在windows)
开源项目地址: Github
- 由于此项目的composer配置有问题, 所以不clone下来, 而是自己新建
- 1.在windows新建一个空白目录
- 2.直接安装composer官方扩展
composer require workerman/workerman
- 3.在根目录下创建src目录, 再添加JT808.php文件
- 4.在根目录添加客户端测试文件client.php, 然后终端输入php client.php 即可测试
<?php
namespace lttxws;
class JT808 {
public static $sequenceNumber = 0; //流水号初始值
