[原创]Loadrunner时间函数、用时间…

Loadrunner中取时间函数、用时间函数生成订单编号例子：

<如要转载，请注明网络来源及作者:Cheers_Lee>

问题的提出：

（1）有时候在Loadrunner中用C语言设计脚本时却要取系统时间；

（2）需要用时间生成唯一订单号；

（3）时间函数加随机数产生不重复的订单号;

一、取系统时间:

Action()
{
lr_save_datetime("现在是：%Y年%m月%d日%H时%M分%S秒", DATE_NOW,"pNextWeek_date");
lr_output_message("%s",lr_eval_string("{pNextWeek_date}"));

 

lr_save_datetime("下周这个时间是：%Y/%m/%d/%H:%M:%S", DATE_NOW +(ONE_DAY * 7), "pNextWeek_date");
lr_output_message("%s",lr_eval_string("{pNextWeek_date}"));

 

lr_save_datetime("%Y%m%d%H%M%S", DATE_NOW,"pNextWeek_date");
lr_output_message("用时间函数生成订单号：%s",lr_eval_string("{pNextWeek_date}"));

 return 0;
}

二、收到的启发（时间函数加随机数产生不重复的订单号;）非常有用；

int i;
char OrderId[20];
Action()
{

srand(time(NULL)); //特别注意：加上这句，每次取不同的随机值

i=rand()%10;
lr_save_datetime("%Y%m%d%H%M%S", DATE_NOW,"now");

sprintf(OrderId,"%s%d",lr_eval_string("{now}"),i);

lr_output_message("订单号为：%s",OrderId);
 return 0;
}

更多时间格式函数参考lr_save_datetime（）函数及DatetimeFormat Codes （如下表）。

Datetime Format Codes

The following format codes are supported forlr_save_datetime.
