标题: 加急～～～～loadrunner如何获取网页图片~~~~请高手指点
现在公司有个任务，50个用户同时登陆一个地图网页，并能查看到这个地图的图片，并要保存这些图片到本地~
注：每个用户登陆到这个网页，服务端会生成一个临时图片供用户查看，也就是说，50个用户同时登陆的时候，查看的是不同的图片。

录制源码如下，请高手赐教：

/*这个是域验证用户名和密码，登陆到网页
web_set_user("tgms\\{user}",
lr_decrypt("{pass}"),
"192.0.1.124:80");
/*请求的是这个URL
web_url("data.asp","URL=http://192.0.1.124/gisrct/data.asp?clientMapWidth=822&clientMapHeight=414",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
EXTRARES,
"URL=images/TGMS.gif", "Referer=http://192.0.1.124/gisrct/data.asp?clientMapWidth=822&clientMapHeight=414", ENDITEM,

/*就是生成的这张图片名，要求保存到本地，最终50个用户取图片
"URL=http://webgissrv/output/SDEGIS_WEBGISSRV20362592484.png", "Referer=http://192.0.1.124/gisrct/data.asp?clientMapWidth=822&clientMapHeight=414", ENDITEM,

"URL=images/pixel.gif", "Referer=http://192.0.1.124/gisrct/data.asp?clientMapWidth=822&clientMapHeight=414", ENDITEM,
LAST);

急啊急，请高手赐教

没人回复。。。

不过已经找到解决方案了。发出来供大家学习

Action()
{

int iflen;
long ifbody;

//strncpy(tempstr2,strtmp,2);
//lr_output_message( tempstr2=%s,tempstr2);

lr_rendezvous("登陆");
lr_think_time(10);

web_set_user("tgms\\{user}",
lr_decrypt("{pass}"),

web_reg_save_param("imgURL" , "LB=src=\"" , "RB=\"" ,"Search=body", LAST);
web_reg_save_param ("fcontent" , "LB=" , "RB=" , "SEARCH=BODY" , LAST);

/* Request with GET method to URL "http://192.0.1.124/gisrct/data.asp?clientMapWidth=822&clientMapHeight=414" failed during recording. Server response : 401*/

web_url("data.asp",

}

{
lr_output_message("length is 0");
}

看着有点显，没注释

代码太长，哪里修改了
