1、设置相关1.1、仓库使用ssh模式clone到本地1.2、仓库添加部署公钥2、服务器配置2.1、切换到PHP-FPM运行账户，无法切换时修改 /etc/passwd2.2、使用PHP-FPM运行账户生成gitee指定的公钥ssh-keygen -t ed25519 -C "xxxxx@xxxxx.com" 2.3、将公钥部署到gitee项目的公钥配置中2.4、测试公钥是否成功ssh -T git@gitee.com3、PHP代码<?php /** * 自动更新钩子 * 修改密钥及项目路径即可使用 **/ //以流的方式读取 $requestBody = file_get_contents("php://input"); if (empty($requestBody)) { die('send fail'); } $requestBody = json_decode($requestBody,true); //加密字符串 $secret_post = $requestBody['sign']; //时间戳参数，单位毫秒级
