我在c/s结构的系统压力测试时,碰到有数据是需要做动态关联的,也就是说,要从服务器返回的数据中截取固定长度的字符存成参数,然后发出去的时候把要变化的内容就使用此参数值,现在碰到的问题是,在脚本调试时,没有问题,在场景里运行的时候,只要有10个并发,就会提示保存参数出错,实在找不到原因了,只有请教高人了,脚本代码如下:
Vuser_init.c

#include "lrs.h"
vuser_init()
{
lrs_startup(257);
lrs_set_recv_timeout(2,0);
lrs_set_recv_timeout2(2,0);

lr_output_message("SessionId=%s",lr_eval_string("<SessionId>"));

//logout
return 0;
}
vuser_end.c
/*********************************************************************

#include "lrs.h"
vuser_end()

lrs_set_recv_timeout2(2,0);
lr_think_time(14);
lrs_send("socket0", "buf30", LrsLastArg);
lrs_receive("socket0", "buf31", LrsLastArg);
lrs_close_socket("socket0");
lrs_cleanup();
return 0;
}
在场景里跑时,提示 lrs_save_param("socket0", NULL, "cm", 1454, 36)这句代码保存参数失败
