JMeter JSON Path 与 BeanShell PostProcessor配置

JMeter测试Http请求时，通常需要分析Response数据，并作为下一次Request的参数，可以使用JSON Path处理器或者BeanShell处理器

JSON Path PostProcessor

BeanShell PostProcessor

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import java.io.*;
import java.util.*;
try
{
	String response_data = prev.getResponseDataAsString();
	JSONArray respArray = JSON.parseArray(response_data);
	for(Iterator it=respArray.iterator();it.hasNext();)
	{
		JSONObject obj = (JSONObject)it.next();
		String newId = vars.get("instanceId");
		String instanceId = (String)obj.get("instanceId");
		if(newId.equals(instanceId))
		{
			String instWorkitemId = (String)obj.get("id");
			String instProcessId = (String)obj.get("instProcessId");
			String instActivityId = (String)obj.get("instActivityId");
			vars.put("instProcessId",instProcessId);
			vars.put("instActivityId",instActivityId);
			vars.put("instWorkitemId",instWorkitemId);
			log.info("2   instProcessId=== "+instProcessId+",instActivityId="+instActivityId+",instWorkitemId="+instWorkitemId);
		}
	}
}
catch(Exception e)
{
	log.info(e.getMessage());
}



//vars.put("result", "1234");

解析JSON需要第三方包fastjson.jar

将fastjson-1.2.54.jar复制到JMeter/lib/ext目录下

使用提取的变量
