1、prev（用于后置处理器、断言）

• prev 提供对当前取样器结果的访问能力
• prev 映射 org.apache.jmeter.samplers 的 SampleResult 类
• 官方文档： https://jmeter.apache.org/api/org/apache/jmeter/samplers/SampleResult.html

log.info("数据类型："+prev.getDataType());
log.info("接口地址："+prev.getUrlAsString());
log.info("请求头信息："+prev.getRequestHeaders());
log.info("响应头信息："+prev.getResponseHeaders());
log.info("响应码："+prev.getResponseCode());
log.info("响应体"+prev.getResponseDataAsString());
log.info("内容类型："+prev.getContentType());
log.info("媒体类型："+prev.getMediaType());
log.info("结果文件名："+prev.getResultFileName());
log.info("线程名称："+prev.getThreadName());
log.info("请求名称："+prev.getSampleLabel());
log.info("消息："+prev.getResponseMessage());
log.info("接口请求结果："+(prev.isSuccessful()?"成功":"失败"));

2、sampler（用于前置处理器）

https://jmeter.apache.org/api/org/apache/jmeter/samplers/Sampler.html

log.info("http请求名："+sampler.getName());
log.info("接口请求地址："+sampler.getUrl().getPath());
log.info("接口请求域名："+sampler.getUrl().getHost());

3、sampler（只能用于Bean Shell 断言）https://jmeter.apache.org/api/org/apache/jmeter/samplers/SampleResult.html

log.info("响应数据："+SampleResult.getResponseDataAsString());
log.info("响应码："+SampleResult.getResponseCode());
log.info("接口名称："+SampleResult.getSampleLabel());
log.info("请求url："+SampleResult.getUrlAsString());
log.info("请求头请求地址请求体："+SampleResult.getSamplerData());
log.info("请求头："+SampleResult.getRequestHeaders());

4、vars

https://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterVariables.html

#获取变量
vars.get("variable_name")
#设置变量
vars.put("variable_name", "variable_value")
#删除变量
vars.remove("variable_name");
#创建或更新具有不必为字符串的值的变量
vars.putObject("obj",new Object());
