使用loadrunner进行压力测试之----post请求
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}"));

42 web_submit_data("postname",

53 "Name=from","Value=diy",ENDITEM,

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，从此结束计时转自：51testing论坛
