关联函数的位置 自我总结
关联函数目前只用到了两种形式
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);
其中usersession是loadrunner的参数名或者参数数组名。
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
一般关联函数都是放到出现动态返回参数的录制响应函数之上,第一个非资源和脚本的响应之前,就可可以了
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",
"Resource=1",
"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",
ITEMDATA,
"Name=userSession", "Value={usersession}", ENDITEM,
"Name=username", "Value=test001", ENDITEM,
"Name=password", "Value=123456", ENDITEM,
"Name=JSFormSubmit", "Value=on", ENDITEM,
"Name=login.x", "Value=53", ENDITEM,
"Name=login.y", "Value=12", ENDITEM,
LAST);
