Jmeter工具bean shell使用总结

1.samper对象（用于前置处理器）

a.sampler （是Samper对象）

参考http://jmeter.apache.org/api/org/apache/jmeter/samplers/Sampler.html

import org.apache.jmeter.config.Arguments;
         
         a)获取http请求的 url
           String url = sampler.getPath();
         b)获取http请求的body内容           
           Arguments arguments = sampler.getArguments(); // 调用时注意sampler小写
          String body = arguments.getArgument(0).getValue();
           

示例代码（将请求体body转化为json/map等数据格式）：

import com.alibaba.fastjson.*;
import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.JSON;
import com.tuhu.open.sdk.sign.Signer;
import java.util.Map;

//defing the privateKey for sign
private static final String PRIVATE_KEY = "${publicKey}";

String date = "${__time(,)}";
vars.put("timestamp", date);

Arguments arguments = sampler.getArguments(); 
Argument arg = arguments.getArgument(0);
String body = arg.getValue();
log.info("=body=****************"+ body);

//JSONObject json = JSONObject.parseObject(body);
//log.info("=json=****************"+ json);

Map map = (Map)JSON.parseObject(body);
log.info("=map=****************"+ map);

//generate the sign by class Signer which offered by developer
Signer signer = new Signer(PRIVATE_KEY);
sign = signer.sign(map, PRIVATE_KEY, "UTF-8", "RSA2");
log.info("=sign=****************"+ sign);

JSONObject parseObject = JSON.parseObject(body);
log.info("=parseObject=****************"+ parseObject);

parseObject.put("sign",sign);
String  postData = parseObject.toJSONString();

//set the date into request
arg.setValue(postData);

c.Jmeter beanshell 跨线程组传值(设置全局属性)

• put值

String str = vars.get("accountNoSetup");
props.put("accountNo",str);
           

• get值

vars.put("accountNo",props.get("accountNo"));
