计算响应数据中字符串出现的次数 [英] Count the number of occurences of a string in response data

问题描述

我想从jmeter中的响应中搜索一个字符串，并根据要使用if控制器运行下一个请求的次数来计算发生的次数.我被用来计数发生次数的代码所困

I want to search a string from a response in jmeter and count the number of occurences based on which i want to use a if controller to run the next requests. I am stuck with the code for counting the occurences

推荐答案

您可以通过至少两种方式来做到这一点:

You can do it in at least 2 ways:

1. 使用正则表达式提取器:

• 将正则表达式提取器添加为请求的子代.

• 配置如下:

• Add Regular Expression Extractor as a child of the request.

• Configure it as follows:

• 参考名称:任何有意义的内容，即count
• 正则表达式:您要计数的字符串，即JMeter
• 模板:$1$
• 比赛编号:-1

• Reference Name: anything meaningful, i.e. count
• Regular Expression: string you want to count, i.e. JMeter
• Template: $1$
• Match No: -1

匹配数将存储在${count_matchNr} JMeter变量

The number of matches will be stored in ${count_matchNr} JMeter Variable

使用 Bean Shell PostProcessor

• 将Beanshell PostProcessor添加为请求的子项

• 将以下代码放入PostProcessor的脚本"区域

• Add Beanshell PostProcessor as a child of the request

• Put the following code into the PostProcessor's "Script" area

import org.apache.commons.lang.StringUtils;

String response = new String(data);
int count = StringUtils.countMatches(response, "JMeter");

log.info("Found " + count + " \"JMeter\" words at the " + prev.getUrlAsString() + " URL");
vars.put("count", String.valueOf(count));

您将能够将匹配计数引用为${count} JMeter变量

You'll be able to refer the matches count as ${count} JMeter Variable
