jmeter beanshell 之常用的代码

fastjson下载和org.json下载，在本文最后面附上下载连接。自行下载。

jmeter beanshell 获取浮点、整数型、字符串型变量

代码如下：

float test= Float.parseFloat(vars.get("test")); //获取浮点数test变量的值

int test= Integer.parseInt(vars.get("test"));//获取整数型test变量的值

String test= vars.get("test");//获取字符串型test变量的值

精确保留小数点后两位

1、jmeter beanshell 求精确到最后两位数，要求四舍五入

代码如下：

import java.text.DecimalFormat;
//四舍五入
DecimalFormat mFormat = new DecimalFormat("#.00");

String test = mFormat.format(test); //将test变量四舍五入

2、jmeter beanshell 求精确到最后两位数，直接截取不做四舍五入

代码如下：

import java.text.DecimalFormat;
DecimalFormat mFormat = new DecimalFormat("0.00");

String test = mFormat.format(test); //将test变量直接截取保留小数点后两位，不做四舍五入

beanshell--替换数组中的某个字段/替换json的某key的value值，直接用jsonobject.put("isShow", true);

举例如下：

/*  返回的response data 信息参考如下
{"code":200,"data":{"auditor":null,"status":1,"storageGoodsList":[{"abstracts":null,"allocateQuantity":null,"allocateReason":null,"businessType":"DGRK","createdTime":"2020-08-06 17:31:08","createdUser":null,"expireTime":"2020-08-06 00:00:00","goodsId":"1290829975123123","goodsName":"商品测试","goodsNo":"10011003100400020","goodsStock":0,"id":"1291305800404307971","inSurplusQuantity":null,"isShow":0,"meteringUnit":"个(1箱)","outQuantity":13,"outSurplusQuantity":null,"perPrice":100.00,"productNo":"H012020062900000144","productTime":"2020-08-06 00:00:00","profit":39.00,"promotionId":null,"purchasePrice":100.00,"realInQuantity":13,"relationId":"1291305800404307970","remark":"物品信息备注---自动化测试脚本","saleAmount":1300.00,"sellingPrice":103.00,"skuValue":"重量:200g;包装:10小包;","stockBatchNo":"200806173100001","stockUnit":"个(1箱)","storageCode":"DG320506001","storageName":"仓库测试）","subtotalAmount":1300.00,"surplusQuantity":null,"taxRate":1.00,"totalAmount":1287.13,"typeCode":null,"unitRate":1.00,"updatePurPrice":null,"updateStock":null,"updatedTime":null,"updatedUser":null}],"supplierId":0,"supplierName":"供应商A","typeCode":"DG_IN_STORAGE_1"},"message":"请求成功","success":true
}
*/import java.util.*;
import com.alibaba.fastjson.*;String response_data = prev.getResponseDataAsString();
JSONObject data_obj = JSONObject.parseObject(response_data);
//返回response中获取数组storageGoodsList
JSONArray dataArray = data_obj.get("data").getJSONArray("storageGoodsList");//数组转成JSONObject。第一组
JSONObject storageGoodsList=(JSONObject)dataArray.getJSONObject(0);
//log.info("打印====================================="+storageGoodsList);
//替换JSONObject中的isShow为true
storageGoodsList.put("isShow", true);
//log.info("打印====================================="+storageGoodsList);
//JSONObject再换成字符串
String str = JSON.toJSONString(storageGoodsList);
String goodsList = "["+str+"]";
log.info("打印====================================="+goodsList);vars.put("goodsList",goodsList);

jmeter beanshell 求范围内随机数

方式1、

//取一定范围内的随机数，前闭后开
public static int getRandNo(int min,int max){
Random random = new Random();
int randNo = random.nextInt(max)%(max-min+1) + min;
return randNo;
}

方式2、

//取一定范围内的随机数，前闭后闭

public static int getRandNo(int min,int max){
       Random random = new Random();
       int randNo = random.nextInt(max-min+1) + min;
       return randNo;
}

有两个json包，大同小异。请自己选择。一个是阿里巴巴的json包，一个是普通的json包。
