注意事项：
1、log只能打印string,不能打印int，需转换
int len = Provincelist_str.length(); String strlen = Integer.toString(len);
或 log.info("code="+object.get("code").getAsInt().toString());
2、众多代码BeanShell都可现在idea中测试通过后在复制到jmeter中使用
整理了一批jmeter常用的beanshell脚本供大家参考！
时间戳
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
try{
Date date =new Date(); //获取当前时间
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String nowDate = sf.format(date);
Calendar cal = Calendar.getInstance();
cal.setTime(sf.parse(nowDate));
cal.add(Calendar.DAY_OF_YEAR,+0);
String orderDate = sf.format(cal.getTime());
cal.add(Calendar.DAY_OF_YEAR,+365);
String senderDate = sf.format(cal.getTime());
vars.put("orderDate",orderDate); //参数可以调用
vars.put("senderDate",senderDate); //参数可以调用
}
catch(Exception e){
}

解析jsonlist
利用beanshell获取到json响应，然后通过JSONObject 和JSONArray 将数组解析，遍历数组的length之后，提取参数值
我们需要解析如下的json响应，提取出中间的Name和population

1.log 打印日志，写入信息到jmeber.log文件。2.SampleResult 获取SampleResult对象，能通过这个对象获取想要的信息。3.Response 获取Response对象，能通过这个对象获取响应信息。4.Failure 查看接口调使用能否成功，假如返回false是成功的，true是失败的。5.FailureMessage 失败信息，没有设置的时候失败信息是空的，能set这个信息。6.ResponseData 获取response body类型是byte[]。7.ResponseCode 返回接口code成功是200。8.ResponseMessage 获取msg成功是OK。9.ResponseHeaders 获取接口服务端返回的头部信息。10.RequestHeaders 获取用户端请求的头部信息。11.SampleLabel 获取接口请求的名称。12.SamplerData 获取请求的url和body。13.ctx 代表上下文信息，能直接用。14.vars即JMeterVariables，操作jmeter变量，这个变量实际引用了JMeter线程中的局部变量容器（本质上是Map），常用方法：a) vars.get(String key)：从jmeter中获得变量值；b) vars.put(String key，String value)：数据存到jmeter变量中；15.prev 获取前面的sample返回的信息，常用方法：a) prev.getResponseDataAsString()：获取响应信息。b) prev.getResponseCode() ：获取响应code。<br><br> |
