在测试中,有时候会遇到要统计响应结果中某个参数出现了多少次,如果量级很大,一个一个数不太现实,下面讲一下实现自动打印出该参数出现的次数的方法。
例如我的响应信息为:{"ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1","ip":"1.1.1.1",}
现在请求上创建正则表达式提取器,把响应信息全部提取到变量中如下面的截图:
然后创建一个beanshell前置处理器,脚本如下:
import java.util.regex.Matcher;
import java.util.regex.Pattern; ip = vars.get("ip");
subs = "\"ip\"";
Pattern pattern = Pattern.compile(subs);
Matcher matcher = pattern.matcher(ip);
int count=0; while(matcher.find()){
count++;
}
System.out.println(count);
执行Jmeter,控制台就打印出数值了
