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
文章来源：https://www.toymoban.com/news/detail-416456.html
//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);
