LoadRunner中，对字符串进行Base64编码

1、在LoadRunner中新建协议为http/html的项目，名称例如“test”。

2、把下面的内容保存到.h格式的文件中(文件名称例如 Base64.h)，并把文件复制到LoadRunner项目（test）的根目录。

/*
Base 64 Encode and Decode functions for LoadRunner
用于LoadRunner的 Base 64 编码和解码功能
==================================================
This include file provides functions to Encode and Decode
LoadRunner variables. It's based on source codes found on the
internet and has been modified to work in LoadRunner.

这个include文件提供的方法是为了对LoadRunner变量进行编码和解码。
它根据在网上发现的源码进行修改并运行于LoadRunner中。

}

3、打开test项目，设置成脚本模式，在左侧边栏右键–“向脚本添加文件”，把Base64.h文件添加进来。

4、打开globals.h，添加头文件Base64.h

#ifndef _GLOBALS_H#define _GLOBALS_H//--------------------------------------------------------------------// Include Files#include "lrun.h"#include "web_api.h"#include "lrw_custom_body.h"#include "base64.h"  //添加头文件Base64.h
