1. vars   API:http://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterVariables.html

vars.get("");

vars.put("",XXX);

2. log

log.info("xxx");

3.ctx   API:http://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterContext.html

ctx.getThreadNum()

4.props 

encoding = props.get("sampleresult.default.encoding");
log.info("sampleresult.default.encoding="+encoding);

5.prev  API:http://jmeter.apache.org/api/org/apache/jmeter/samplers/SampleResult.html

System.out.println(prev.getResponseCode());
System.out.println(prev.getResponseDataAsString());
prev.setResponseCode("222");
System.out.println(prev.getResponseCode());
prev.setResponseMessage("qiaoyeye你好");
System.out.println(prev.getResponseMessage());
prev.setResponseData("qiaoyeye你好","UTF-8");
System.out.println(prev.getResponseDataAsString());
System.out.println(${port});
System.out.println(ctx.getThreadNum());

使用：

在beanshell中使用。如在BeanShell PreProcessor中：

log.info("内置变量练习开始");

ipString = vars.get("ip");

log.info("ipString="+ipString);

vars.put("newip",ipString);
log.info("newip="+vars.get("newip"));

encoding = props.get("sampleresult.default.encoding");
log.info("sampleresult.default.encoding="+encoding);

运行结果：

在BeanShell PostProcessor中：

System.out.println(prev.getResponseCode());
System.out.println(prev.getResponseDataAsString());
prev.setResponseCode("222");
System.out.println(prev.getResponseCode());
prev.setResponseMessage("qiaoyeye你好");
System.out.println(prev.getResponseMessage());
prev.setResponseData("qiaoyeye你好","UTF-8");
System.out.println(prev.getResponseDataAsString());
System.out.println(${port});
System.out.println(ctx.getThreadNum());

运行结果：
