1. 发送post请求时使用web_submit_data
如：1 web_submit_data("create",//事务名2. 如果要发送的请求的数据值需要变化，那么需要将请求中的值参数化，，如果是根据上一条请求的返回值来确定请求中的数据值，那么需要对上一条请求的返回值进行解析如：
2 "Action=http://bizhi.sogou.com/diy/", //请求域名
3 "Method=POST", //请求类型为post
4 "RecContentType=application/json", //返回格式为json
5 "Referer=http://bizhi.sogou.com/diy?wp_id=8743",
6 "Snapshot=t4.inf",
7 "Mode=HTML",
8 ITEMDATA, //下面编辑post请求的数据
9 "Name=img", "Value=http://dl.bizhi.sogou.com/images/2012/05/3/8743.jpg", ENDITEM, //数据的name、value及结束符

4. 如果一个action中有两个请求，那么压测是看到的响应时间曲线是两个请求综合的响应时间，如果要区分每个请求的响应时间，可加入请求开始/结束标记
1 lr_start_transaction(“create”);//插入结束标记，从此结束计时
2 lr_end_transaction(“create”, LR_AUTO);//插入结束标记，从此结束计时
