【jmeter系列】Jmeter将响应数据结果保存到csv文件的两种方式(Bean Shell)

背景

日常接口测试,需要将接口返回值对应的字段数据保存下来

示例接口:

post请求:

https://dev-xxx-bot.igovee.com/text

{
"text":"I really need some meditative effects."
}

实现方法

方式一(Jmeter BeanShell采样器提取接口)

接口获取response数据:

{"cost_time":0.15606689453125,"emotion_class":{"label":"hope","score":0.2862275540828705},"entity":null,"entity_class":{"label":"plants","score":0.2635917663574219},"keywords":"fruit"}

jmeter线程组-JSR223 Sampler

 代码实例:

//导入json包
import org.json.JSONObject;
import org.json.JSONArray;
import org.apache.jmeter.samplers.SampleResult
SampleResult rsp =ctx.getPreviousResult()        
String response_data = rsp.getResponseDataAsString()  //获取上一个接口返回数据,此处是String类型
log.info("\n" + response_data)
//将String类型的返回值构造成JSONObject对象
JSONObject jsonstring=new JSONObject(response_data);  //放进json对象里
String cost_time=jsonstring.get("cost_time").toString();        //取出cost_time对应的value值
String score=jsonstring.get("emotion_class").get("score").toString();        //取出score对应的value值
vars.put("cost_time",cost_time);
vars.put("score",score);
log.info(cost_time);
log.info(score);
//写入文件
FileWriter fstream=new FileWriter("E:/gongju/jmeter/pc.csv",true);//本地存储文件路径
BufferedWriter out = new BufferedWriter(fstream);
out.write(cost_time);//提取出来的cost_time
out.write(",");//换列
out.write(score);//提取出来的score
out.write(System.getProperty("line.separator"));//换行
out.close();
fstream.close();

写入CSV效果如下: 

方式二(json提取器+BeanShell 取样器)

1、json提取器提取出变量对应的value值

 2、beanshell取样器

 示例代码:

File file=new File("E:\\gongju\\jmeter\\pc1.csv");
FileWriter fw=new FileWriter(file,true);
BufferedWriter out=new BufferedWriter(fw);
		out.write(vars.get("cost_time"));
		out.write(",");//换列
		out.write(vars.get("score"));//提取出来的score
		out.write(System.getProperty("line.separator"));//换行
		out.close();
		fw.close();

结果文件:

备注:

JMeter运行时报Typed variable declaration : Class: JSONObject not found in namespace解决方案

因为${JMETER}\lib\下缺少json.jar包,下载链接如:
