Lr_get_transaction_think_time函数使用问题

kuangquanshui · 发表于 2010-9-21 09:55:09

使用Lr_get_transaction_think_time的时候获取不到思考时间？预期输出的是6，但每次输出都是0，
   以下是我的脚本，
Action()
{
int time ;

下面是帮助中的例子
double think_time;

lr_start_transaction ("Flight");

web_url("home;sz=234x60;tile=1;ord=977672495775323400",

      "URL=http://ad.doubleclick.net/...ord=977672495775323400",

      ..

      "Mode=URL",

      LAST );

think_time=lr_get_transaction_think_time("Flight");

status = web_submit_data("flight",

      "Action=http://www.mercury-tours.com/cgi-bin/tours?ITN_RESPONSE+",

      "Method=POST",

      "TargetFrame=",

      ...

      LAST );

/* End transaction with operation result - pass or fail */
if (status == 0)

lr_end_transaction("Flight", LR_PASS);

      else

lr_end_transaction("Flight", LR_FAIL);

if (think_time)

lr_output_message("The transaction think time is %f seconds", think_time);

else

lr_output_message("The think time cannot be determined.");
