Loadrunner对字符串进行Base64加密，有童鞋实现的吗？

我在网上搜了个base64.h的头文件
/*
Base 64 Encode and Decode functions for LoadRunner
==================================================
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.

在脚本中 #include "base64.h"

但是运行脚本，提示base64.h文件中有好多语法错误：
C:\\Program Files (x86)\\HP\\LoadRunner\\include/base64.h (32): syntax error; found `{' expecting `;'
C:\\Program Files (x86)\\HP\\LoadRunner\\include/base64.h (32): skipping `{'
C:\\Program Files (x86)\\HP\\LoadRunner\\include/base64.h (52): undeclared identifier `base64decode_lut'

C:\\Program Files (x86)\\HP\\LoadRunner\\include/base64.h (52): type error: pointer expected
C:\\Program Files (x86)\\HP\\LoadRunner\\include/base64.h (52): type error: pointer expected


有同学知道怎么解决吗？

是你要传加密值过去？

    b64_encode_string("123456","base64");
    lr_output_message(lr_eval_string("<base64>"));
这样引用，没有问题啊 只是返回值只有8位长度
