1. 发送post请求时使用web_submit_data
如：
1 web_submit_data("create",//事务名 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 10 "Name=left", "Value=60", ENDITEM, //第二条数据的name、value及结束符 11 "Name=top", "Value=30", ENDITEM, 12 "Name=width", "Value=720", ENDITEM, 13 "Name=height", "Value=450", ENDITEM, 14 "Name=model", "Value=5/5s", ENDITEM, 15 "Name=x", "Value=1", ENDITEM, 16 "Name=y", "Value=1", ENDITEM, 17 "Name=ofc", "Value=1", ENDITEM, 18 "Name=wp_id", "Value=8743", ENDITEM, 19 "Name=mat", "Value=ms", ENDITEM, 20 "Name=curMode", "Value=normal", ENDITEM, 21 LAST);
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：
1 web_submit_data("create", 2 "Action=http://bizhi.sogou.com/diy/", 3 "Method=POST", 4 "RecContentType=application/json", 5 "Referer=http://bizhi.sogou.com/diy?wp_id=8743", 6 "Snapshot=t4.inf", 7 "Mode=HTML", 8 ITEMDATA, 9 "Name=img", "Value=http://dl.bizhi.sogou.com/images/2012/05/3/8743.jpg", ENDITEM, 10 "Name=left", "Value=60", ENDITEM, 11 "Name=top", "Value=30", ENDITEM, 12 "Name=width", "Value=720", ENDITEM, 13 "Name=height", "Value=450", ENDITEM, 14 "Name=model", "Value=5/5s", ENDITEM, 15 "Name=x", "Value=1", ENDITEM, 16 "Name=y", "Value=1", ENDITEM, 17 "Name=ofc", "Value=1", ENDITEM, 18 "Name=wp_id", "Value=8743", ENDITEM, 19 "Name=mat", "Value=ms", ENDITEM, 20 "Name=curMode", "Value=normal", ENDITEM, 21 LAST);//请求1 22 23 lr_set_debug_message( 16 | 2,0 ); 24 lr_save_string((char*)strtok(lr_eval_string("{Output}"),","),"temp");//获得请求1的返回数据 25 //lr_output_message("bian:%s",lr_eval_string("{temp}")); 26 lr_save_string((char*)strtok(NULL,","),"diyid_temp");//解析返回数据 27 //lr_output_message("bian2:%s",lr_eval_string("{diyid_temp}")); 28 lr_save_string((char*)strtok(lr_eval_string("{diyid_temp}"),":"),"temp");//解析返回数据 29 //lr_output_message("bian:%s",lr_eval_string("{temp}")); 30 lr_save_string((char*)strtok(NULL,":"),"diyid_temp");//解析返回数据 31 //lr_output_message("bian2:%s",lr_eval_string("{diyid_temp}")); 32 diyid_str=(char*)strtok(lr_eval_string("{diyid_temp}"),"}"); 33 lr_save_string((char*)strtok(lr_eval_string("{diyid_temp}"),"}"),"diyid");//解析返回数据 34 //lr_output_message("bian:%s",lr_eval_string("{diyid}")); 35 36 strcat(test, diyid_str); 37 //lr_output_message("%s",test); 38 lr_save_string(CMd5(test),"md5");//计算md5 39 //lr_output_message("bianmd5:%s",lr_eval_string("{md5}")); 40 41 42 web_submit_data("postname", 43 "Action=http://bizhi.sogou.com/orderpay/", 44 "Method=POST", 45 "RecContentType=textml", 46 "Mode=HTML", 47 ITEMDATA, 48 "Name=goods_action","Value=goods_detail",ENDITEM, 49 "Name=goods_addr","Value=656",ENDITEM, 50 "Name=md5str","Value={md5}",ENDITEM,//根据参数构造请求 51 "Name=diy_id","Value={diyid}",ENDITEM,//根据参数构造请求 52 "Name=goods_info","Value=448_1",ENDITEM, 53 "Name=from","Value=diy",ENDITEM, 54 "Name=Accept","Value=text/plain",ENDITEM, 55 LAST);
3. 另附，计算md5，需要添加md5的头文件，并别忘了在gloab.h中include md5.h

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
