loadrunner12.55：登录功能--手动关联【示例】

示例1：

该平台登录过程及脚本实现过程如下：

1、通过“http://10.248.57.226:9010/user-center/user-info/publicKey?machineFlag=1&randomStr=1395644086717349888”请求获取响应报文中的publicKey及randomStr字段；（脚本保存publicKey字段到文件publicKey.txt中，同时保存randomStr字段为参数{ResprandomStr}）

2、根据获取的publicKey生成用户名和密码的密文；（脚本通过批处理文件getEncrypt.bat调用Java应用生成密文并分别保存至文件userName.txt和passwd.txt中，通过lr_read_file()函数读取密文到参数{name}和{passwd}中）

3、根据生成的密文发起请求http://10.248.65.91:8010/user-center/user/login?machineFlag=1&pwd={passwd}&userName={name}&randomStr={ResprandomStr}完成用户名和密码验证，并返回重定向URL及授权token；（脚本使用参数{name}、{passwd}、{ResprandomStr}发起请求获取响应头中的location字段，即重定向URL及token）

4、凭借token和重定向URL开展后续会话；

脚本调用JAVA应用的批处理文件 getEncrypt.bat ：

@echo off
set filepath=%~dp0

call cd %filepath%
call javac -encoding UTF-8 Encrypt2.java
call java Encrypt2 


::pause
