1. controller入口

    @ApiOperation("模拟平台端+现场机socket交互过程,需要Authorization")@PostMapping(path = "/testSocketBusiness")public ResponseBean<HashMap<Object, Object>> testSocketBusiness(@RequestBody SocketTestClient.SocketAllParams socketAllParams) {// 建立socket连接  "\n")HashMap<Object, Object> res = socketTestClient.doTestAll(socketAllParams.getFirstUrlRequest(), socketAllParams.getSocketMsgList(), socketAllParams.getAutoUseNowDataTime());return new ResponseBean<>(200, "请求结束", res);}

1.1 接口入参示例及说明

{"firstUrlRequestxxxxx": {"url": "/your http api/remoteControl","method": "PUT","urlParams": {"monitorId": 3319,"cn": "3020","polId": "md0501","infoId": "i42002"}},"socketMsgList": ["ST=32;CN=3020;PW=123456;MN=887799;Flag=5;CP=&&DataTime=20250529105000;PolId=md0501;DT=201;VaseNo=4;i33022-Info=0;i33028-Info=1&&"],"autoUseNowDataTime": true,"【示例非必要不改动】反控入参示例（前不要长度、不要QN,后不要结尾，DataTime是否自动更新取决于autoUseNowDataTime）": {"firstUrlRequest": {"url": "/your http api/remoteControl","method": "PUT","urlParams": {"monitorId": 3319,"cn": "3020","polId": "md0501","infoId": "i42002"}},"socketMsgList": ["ST=91;CN=9011;PW=123456;MN=7899871;Flag=4;CP=&&QnRtn=1&&","ST=32;CN=3020;PW=123456;MN=7899871;Flag=4;CP=&&DataTime=20250528111758;PolId=md0501;i42002-Info=2&&","ST=91;CN=9012;PW=123456;MN=7899871;Flag=4;CP=&&ExeRtn=1&&"],"autoUseNowDataTime": true},"【示例非必要不改动】监测数据入参示例（前不要长度、不要QN,后不要结尾，DataTime是否自动更新取决于autoUseNowDataTime）": {"socketMsgList": ["ST=32;CN=2011;PW=123456;MN=7899871;Flag=5;CP=&&DataTime=20250527105200;w01018-Rtd=8.8,w00000-Flag=N;w01018-Rtd=444.7,w01018-SampleTime=20250527105100,w01018-Flag=D&&"],"autoUseNowDataTime": false},"一次采集日志：": ["tail -200f /home/logs/yourProject/collect/connect.log","tail -200f /home/logs/yourProject/collect/receive.log [重点]","tail -200f /home/logs/yourProject/collect/send.log","tail -200f /home/logs/yourProject/debug.log [重点]","tail -200f /home/logs/yourProject/error.log"]
}

1.2 接口出参示例

{"code": 200,"msg": "请求结束","data": {"请求结束,当期是监测数据上传模式,返回qn列表：": ["20250529132932726"]},"timestamp": "2025-05-29 13:29:36","traceId": "cb9557eaed1543aa8749bf2a545816ef"
}
