Groovy在JMeter中处理header

import org.apache.jmeter.protocol.http.control.*

def manager = sampler.getHeaderManager()
manager.add(new Header("FunTester","FunTester"))
def h = manager.get(0)
log.info("-------Header : " + h.getName() + "----------- " + h.getValue())
h.setValue("FunTester039029309230")
log.info("-------Header : " + h.getName() + "----------- " + h.getValue())```

* 控制台输出：
