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

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
