关联函数的位置 自我总结

1、  web_reg_save_param("usersession","LB=<input type=hidden name=userSession value=","RB=>",LAST);
2、  web_reg_save_param("usersession","LB=<input type=hidden name=userSession value=","RB=>",“ORD=ALL”，”Savelen=18“，LAST);

LB是动态返回值的左边界
RB是动态返回值的右边界
ORD=ALL是选择所有相同左右边界的字符串都存入参数或者参数数组中
Savelen=18是要存储的字符串的长度
LAST表述函数结合苏位置

例如：

web_url("home.html",
"URL=http://127.0.0.1:1080/WebTours/home.html",
"Resource=0",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/WebTours/welcome.pl?signOff=true",
"Snapshot=t6.inf",
"Mode=HTTP",
LAST);
web_reg_save_param("usersession","LB=<input type=hidden name=userSession value=","RB=>",LAST);
//这个位置就是出现动态参数之前，第一个非资源和脚本响应的位置
//web_url("nav.pl")）之下有一个js脚本和若干个图片类资源
web_url("nav.pl",
"URL=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Resource=0",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/WebTours/welcome.pl?signOff=true",
"Snapshot=t7.inf",
"Mode=HTTP",
LAST);

web_concurrent_end(NULL);

web_concurrent_start(NULL);

web_url("JSFormSubmit.js",
"URL=http://127.0.0.1:1080/WebTours/JSFormSubmit.js",

"RecContentType=application/x-javascript",
"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Snapshot=t8.inf",
LAST);

web_url("mer_login.gif",
"URL=http://127.0.0.1:1080/WebTours/images/mer_login.gif",
"Resource=1",
"RecContentType=image/gif",
"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Snapshot=t9.inf",
LAST);

web_concurrent_end(NULL);

lr_start_transaction("login-0");

lr_think_time(17);
web_submit_data("login.pl",
"Action=http://127.0.0.1:1080/WebTours/login.pl",
"Method=POST",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Snapshot=t10.inf",
"Mode=HTTP",
