LoadRunner生成随机位数的字符串

1、新建生成随机数函数文件randString.h

//生成随机字符串
char *randString(slen)
{
    int i,randid;
    char temp[100]="";
    char character_set[52] = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'};

    for(i=1;i<slen;i++){
        randid = rand()%52;
        sprintf(temp,"%s%c",temp,character_set[randid]);
    }

    return(temp);
}

2、在loadrunner新建脚本，导入随机数函数头文件randString.h

右键新脚本空白区域，选择add files to script,添加头文件：

 

3、编辑globals.h文件

添加脚本：#include "randString.h"

 

 

4、编写action脚本，调用生成随机位数字符串函数

Action(){

char a[100]="";
strcpy(a,lr_eval_string(randString(32)));
lr_output_message("%s",a);
return 0;

}

 

5、执行结果

生成32位随机字符串
