以loadrunner进行压力测试的—-post请求。LoadRunner 中实现MD5加密。

  1. 发送post请求时用web_submit_data 

多年来当为此loadrunner做一个压力测试,在编排脚本的当儿发现传递参数的当儿要一个sign值,这个价是拿参数进行MD5加密生成的,所以下面就说一样说怎么对参数进行MD5加密。

如:

1、首先我们用一个加密算法的公文称:md5.h文件

 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/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);

俺们好新建一个md5.h文件,至于里面具体的算法网上都发下载,具体如下(直接以下的算法拷贝到md5.h文件被):

2.
比方只要发送的求的数据值需要扭转,那么用拿请求中之价参数化,,如果是冲达同长条告的归值来规定要被的数据值,那么得对直达一样漫漫告的归来值进行分析

    184 char CMd5(const char s)
    185 {
    186 struct MD5Context md5c;
    187 unsigned char ss[16];
    188 char subStr[3],resStr[33];
    189 int i;
    190 MD5Init( &md5c );
    191 MD5Update( &md5c, s, strlen(s) );
    192 MD5Final( ss, &md5c );
    193 strcpy(resStr,””);
    194 for( i=0; i<16; i++ ) 195 { 196 sprintf(subStr, "%02x", ss[i] ); 197 itoa(ss[i],subStr,16); 198 if (strlen(subStr)==1) { 199 strcat(resStr,"0"); 200 } 201 strcat(resStr,subStr); 202 } 203 strcat(resStr,"\0"); 204 return resStr; 205 }

2、然后再称这个md5.h文件放到脚本中:

4.
要一个action中生有限个请求,那么压测是张的响应时间曲线是个别独请求综合的应时间,如果要分每个请求的响应时间,可入请求开始/结束标记

图片 1

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

3、然后又以loadrunner中导入该文件,导入时入loadrunner右键点击globals.h文件,再点击Add
Files to Script添加md5.h文书

 添加后loadrunner中不怕时有发生矣这文件:

4、然后在头文件globals.h中加上引用#include “md5.h”

5、现在我们初步调用CMd5()方法开展加密:

Action()
{
char a[100]=”asedrf123dcf876″;
char sign[32];
strcat(sign,CMd5(a));
lr_output_message(“%s”,sign);
return 0;
}

测试的结果如下:

即使这样我们就是加密完成了,最后使做的即使是以公加密的sign值传为要用的地方就尽了
