关联实质是下一个请求发送参数来自于上一个请求的响应值（首先问开发，然后利用lr或fiddler查找比对录制与回放的请求/响应的源文件）：头文件cookie、session、自定义
- 自动关联：菜单User>Scan scripts for correlations
- 手工关联：问开发+查看日志+Fillder请求与响应的源文件
- 调试技巧
1利用lr自身log日志（接口少还可以）
2利用log函数(自己打印)
3利用result（信息有时候不全）
4利用fiddler
=====关联基本提取，例子===
Action()
{
web_reg_save_param("mysessiontest","LB=userSession value=","RB=>",LAST);
web_reg_save_param("mysessiontest","LB=userSession value=","RB=>","NotFound=WARNING",LAST);//此种方式代表找不到参数不报error，只报waring
web_url("WebTours",
"URL=http://127.0.0.1:1080/WebTours/",
"TargetFrame=",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
lr_log_message("mysession is %s",lr_eval_string("{mysessiontest}"));
web_reg_find("Text=Welcome,admin1",
LAST);
lr_think_time(26);
web_submit_data("login.pl",

===========关联数组提取随机值的例子===========
