socket协议录制回放与关联的问题
最近几天一直在做一个C/S模式客户端的测试，用Lr录制没有问题，但是脚本中有大家经常遇到的十六进制乱码问题，回放时遇到Mismatch问题，分析客户端和脚本发现客户端每次连接服务器会接收到一个动态分配的instanceId，位置在buf3,因此必须进行关联，问题是data.ws中的乱码分析和参数化还是有点困难，参数化的结果还是没有解决mismatch问题，而且lrs_output_message的输出也不对，实在很是困惑，希望遇到过这个问题的朋友可以解释一下，以后将这个案例详细说明，给大家做个资料。脚本：
#include "lrs.h"
Action()
{
//lrs_set_receive_option(EndMarker, EndMarker_None);
// lrs_set_recv_timeout2(0,0);
/// lrs_set_receive_option(EndMarker, StringTerminator , "\r\n");
//lrs_set_receive_option(EndMarker, BinaryStringTerminator , "\\X00");
lrs_create_socket("socket0", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket0", "buf0", LrsLastArg);
lrs_receive("socket0", "buf1", LrsLastArg);
lrs_close_socket("socket0");
lrs_create_socket("socket1", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket1", "buf2", LrsLastArg);
lrs_receive("socket1", "buf3", LrsLastArg);
lrs_save_param("socket1","buf2","cctv",0,32);
lr_output_message ("param1: %s", lr_eval_string("<cctv>"));
lrs_close_socket("socket1");
lrs_create_socket("socket2", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket2", "buf4", LrsLastArg);
lrs_receive("socket2", "buf5", LrsLastArg);
lrs_close_socket("socket2");
lrs_create_socket("socket3", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket3", "buf6", LrsLastArg);
lrs_receive("socket3", "buf7", LrsLastArg);
lrs_close_socket("socket3");
lrs_create_socket("socket4", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket4", "buf8", LrsLastArg);
lrs_receive("socket4", "buf9", LrsLastArg);
lrs_close_socket("socket4");
lrs_create_socket("socket5", "TCP", "RemoteHost=xxx.xxx.xxx.xxx:xxxx",LrsLastArg);
lrs_send("socket5", "buf10", LrsLastArg);
lrs_receive("socket5", "buf11", LrsLastArg);
lrs_close_socket("socket5");
return 0;
}
