lr中for循环写入数据参数化脚本

网上达人的如下，不过有错误，后面跟着我修改后的脚本^_^，

“ Lr_save_string()函数和Itoa()函数的使用

/*

目的：使用for循环添加多条有规律的数据，比如说：a1、a2、a3......a1000

方法：从上面看1-1000是一个有序序列，并且前面的a都是固定的，所以只需要用for循环将1-1000循环出来就可以了。

   但是loadrunner使用的是C语言的语法，所以不能向在java中一样，将两个变量直接相加（+）（+：连字符）

   所以这个时候就需要将首先将int变量转换成string，然后再用lr_save_string（）函数将该变量用loadrunner可以识别的参数化方式保存起来，再应用到录制的脚本中就可以了



函数简介：

   int itoa ( int value, char *str, int radix );

   函数目的：将int类型转换成string

   参数介绍：value：要转换的int型的值

               str：目标字符串，即将转换成的string值保存到str中

            radix：转换数字时所用的基数 10：十进制；2：二进制……



   int lr_save_string (const char *param_value, const char *param_name);

   函数目的：将param_value值保存到param_name变量中

   参数介绍：param_value：要保存的值

            param_name：变量名称

问题：为什么要用itoa()和lr_save_string()两个函数相结合使用呢？

   因为lr_save_string()中的两个参数都是char类型的指针，int类型的值必须经过转换才能在lr_save_string()函数中使用，所以此处就要将itoa()和lr_save_string()两个函数相结合使用。

*/

Action()

{

   int i;

   char str[100]; //定义一个数组用来保存int类型转换后的值

   for(i=0;i<=9;i++){

            itoa(i,str,10);

            lr_save_string(str,"ID");

            lr_output_message("==str:=%s==ID:=%s====",str,lr_eval_string("{ID}"));

   }

/*

用lr_save_string()将数组保存到变量中以后就可以应用到Loadrunner录制的脚本中了

{ID}：是loardrunner识别参数的方式

web_url("login",

            "URL=http://server0.im.sonoro.cn:18001/login?username=a{ID}&password=test&autoLogin=false&1211433835878&1211433835878",

            "TargetFrame=",

            "Resource=0",

            "RecContentType=text/html",

            "Referer=http://server0.im.sonoro.cn:18001/proxy.html?1211433821547",

            "Snapshot=t6.inf",

            "Mode=HTML",

            LAST);

*/

   return 0;

}

我录制的一个范例脚本如下：

{

int i;
char str[100]; //定义一个数组用来保存int类型转换后的值
