sockets测试UDP协议ACK返回的一个问题，请各位大神帮忙看看
流程是：1、客户端发起登录请求去获取随机数，UDP格式
2、服务器收到请求后，给客户端返回一个ACK（这个ACK响应是开发人员定义的）和一个401鉴权响应
3、客户端收到鉴权响应后，应该给服务返回一个ACK，表示收到，服务器收到这个ACK后，就不会再重复发送
问题：
1、我们怎么用Lr模拟我们发送给服务器的ACK，下面的脚本是我写的，但通过抓包查看，发现服务器要发送3次的随机数给客户端后，才会继续进行发送ACK的操作，请问这个问题怎么解决，万分感谢
抓包

LR脚本
Action()
{
lrs_create_socket("socket0", "UDP", "LocalHost=18998",LrsLastArg);
lrs_send"buf0", "TargetSocket=10.137.86.5:8089", LrsLastArg
lrs_set_recv_timeout2(5,0);
lr_start_transaction("GetRamom");
lrs_receive("socket0", "buf1", LrsLastArg);
lrs_send("socket0","buf2", "TargetSocket=10.137.86.5:8089", LrsLastArg);
lrs_save_searched_string("socket0",NULL,"RAMOM1","LB=nonce\":","RB=\"",3,1,-1);
lrs_save_searched_string("socket0",NULL,"resultCode","LB=resultCode\"","RB=,",3,1,-1);
if (strcmp(lr_eval_string("<resultCode>"),"401")==0) {
lr_end_transaction("GetRamom", LR_PASS);
}
lr_output_message("resultCode is : %s",lr_eval_string("<resultCode>"));
lr_output_message("RAMOM is : %s",lr_eval_string("<RAMOM1>"));
return 0;
}
LR 获取随机数运行结果：
Action.c(23): Notify: Transaction "GetRamom" ended with "Pass" status (Duration: 11.0700 Wasted Time: 5.0000).
