LoadRunner调用md5方法
上一篇 / 下一篇 2011-04-29 11:25:12 / 个人分类:Loadrunner
有个项目的请求参数中,有一个参数需要md5加密。在google搜索了些LR调用MD5方法的资料。参考资料实现了参数md5加密。现将方法做下总结:51Testing软件测试网-yX!g#^5o+h
51Testing软件测试网dZ7^SI3c~(is'G
1.首先将md5算法在C编译器中生成md5.h文件,在Vuser generator中添加这个md5.h文件,然后再global.h中添加#include "md5.h"头文件51Testing软件测试网)e(Ooz:aQL
'C-Z `/Cs-]02.调用md5方法:lr_output_message("%s",CMd5("test"))
Yg|Z]RC0
K`-_}D0---也可以将md5方法生成dll,然后在LR中调用这个DLL。(此方法没有尝试过)
