loadrunner帮助文档给的示例：
Example 2 is the same as example 1, but because Save Count is used, the script execution is not halted on failure. Instead, the error is handled in the code.
// Run the Web Tours sample
web_url("MercuryWebTours",
"URL=http://localhost/MercuryWebTours/",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST );
// Set up check for successful login by looking for "Welcome"
web_reg_find("Text=Welcome",
"SaveCount=Welcome_Count",
LAST );
// Now log in
web_submit_form("login.pl",
"Snapshot=t2.inf",
ITEMDATA,
"Name=username", "Value=jojo", ENDITEM,
"Name=password", "Value=bean", ENDITEM,
"Name=login.x", "Value=35", ENDITEM,
"Name=login.y", "Value=14", ENDITEM,
LAST );
// Check result
if (atoi(lr_eval_string("{Welcome_Count}")) > 0){
lr_output_message("Log on successful.");
}
else{
lr_error_message("Log on failed");
return(0);
}
注册提交的脚本：
submit()
{
//int registercount = 0;
web_reg_find("Search=Body",
"SaveCount=registerflag",，
"Text=Thank you, <b>{username}</b>",//此处检查的是服务器返回的内容，而不是展示的内容，当去掉<b></b>标签后，无法检查到内容，运行结果是失败的
LAST);
lr_think_time(5);
web_submit_data("login.pl_2",
"Action=http://127.0.0.1:1080/cgi-bin/login.pl",
"Method=POST",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/cgi-bin/login.pl?username=&password=&getInfo=true",
"Snapshot=t7.inf",
"Mode=HTML",
ITEMDATA,
"Name=username", "Value={username}", ENDITEM,
"Name=password", "Value=123", ENDITEM,
"Name=passwordConfirm", "Value=123", ENDITEM,
"Name=firstName", "Value=", ENDITEM,
"Name=lastName", "Value=", ENDITEM,
"Name=address1", "Value=", ENDITEM,
"Name=address2", "Value=", ENDITEM,
"Name=register.x", "Value=45", ENDITEM,
"Name=register.y", "Value=11", ENDITEM,
LAST);
//registercount = atoi(lr_eval_string("{registerflag}"));
if(atoi(lr_eval_string("{registerflag}")) > 0)
lr_output_message("注册成功");
else
lr_output_message("注册失败，错误的账号是：%s",lr_eval_string("{username}"));
return 0;
}
atoi(lr_eval_string("{registerflag} 返回结果是一个数，通过atoi函数将结果转换成int，可以将注释的去掉，if（registercount > 0）也可以有同样效果。
执行过程中多次脚本不报错，但实际结果与运行结果不一致，可以适当手动重复步骤，然后通过浏览器查看源文件可以查看到检查点周围是否有在浏览器界面不展示的信息。
web_reg_find()函数是一个注册函数，需要写在检查内容前面。判断语句写在后面。
