jmeter-BenaShell的使用

BeanShell是一个小型嵌入式Java源代码解释器，具有对象脚本语言特性，能够动态地执行标准JAVA语法，并利用在JavaScript和Perl中常见的松散类型、命令、闭包等通用脚本来对其进行拓展。
前置处理器：请求发送之前对请求参数做一些处理
后置处理器：请求发送完成之后对响应数据进行处理

BeanShell Sampler 取样器
BeanShell PreProcessor 预处理程序
BeanShell PostProcessor BeanShell后置处理器，主要用来对响应数据进行处理
BeanShell Assertion BeanShell断言，主要对后端返回的比较复杂的数据，要进行复杂的业务逻辑处理，进行断言。
_BeanShell 函数

设置随机数
数据加密
响应报文数据提取
数据库数据提取
复杂逻辑结构断言

BeanShell预处理器-随机生成数据

例子：某一平台下的新增接口，随机生成新增的数据

//随机生成一个用户名
public static String getUsername(int length) {
	String str = "abcdefghijklmnopqrstuvwxyz";
	Random random = new Random();
	StringBuffer sb = new StringBuffer();
	for(int i = 0; i < length; i++){
		//生成一个随机的int值
	     int number = random.nextInt(str.length());
		sb.append(str.charAt(number));
	}
	String username = "wangmin" + sb;
	return username.toString();
}

//随机生成一个序列号
public static String getorganizationCode(int length){
	String str = "0123456789";
	Random random = new Random();
	StringBuffer sb = new StringBuffer();
	for(int i = 0; i < length; i++){
		int number = random.nextInt(str.length());
		sb.append(str.charAt(number));
	}
	String organizationCode = "009" + sb;
	return organizationCode.toString();
}


String name = getUsername(3);
log.info(name);
vars.put("name",name);

String organizationCode = getorganizationCode(6);
log.info(organizationCode);
vars.put("organizationCode",organizationCode);

结果：每次运行均随机产生不同数据，运行结果正确，响应状态码：200，message：success

{"errorcode":0,"message":"success!","data":{"operatorId":"2107","name":"wangmingdq","address":"详细地址","contacts":"汪敏","phone":"17664012113","proprietorship":null,"organizationCode":"009051270","longitude":118000000,"latitude":39000000,"status":5,"type":null,"provinceId":"356","cityId":"357","countyId":"358","append":"","createTime":1620457032,"updateTime":1620457032,"imageId":null,"imageUrl":""}}

{"errorcode":0,"message":"success!","data":{"operatorId":"2107","name":"wangmingdq","address":"详细地址","contacts":"汪敏","phone":"17664012113","proprietorship":null,"organizationCode":"009051270","longitude":118000000,"latitude":39000000,"status":5,"type":null,"provinceId":"356","cityId":"357","countyId":"358","append":"","createTime":1620457032,"updateTime":1620457032,"imageId":null,"imageUrl":""}}

BeanShell后置处理器-提取响应内容置于log中

//提取响应内容
String statusCode = prev.getResponseCode(); //获取响应代码
String response_body = prev.getResponseDataAsString(); //获取响应body内容
String response_headers = prev.getResponseHeaders();   //获取响应头
String response_reason = prev.getResponseMessage();   //获取响应信息

log.info("=====响应代码：=====>>"+statusCode);
log.info("=====响应body:=====>>"+response_body);
log.info("=====响应头：=====>>"+response_headers);
log.info("=====响应信息：=====>>"+response_reason);
