Question

我是jmeter的新手。我想做性能测试。我的问题是当我将值从一个http req转换为另一个http请求时，该请求位于控制器的foreach中，请求运行默认值，但它不会选择正则表达式值。我使用jmeter 2.13

这是我的正则表达式提取器 ref name = names

regex=(dentist|ortho|cardio)
template=$1$
match no=-1
default=none

**first http req**
IP-localhost port=8080

path=JmeterJson/speciality

**second req**

IP-localhost port=8080

path=JmeterJson/names?speciality={names}


FOREACH CONTROLLER 
I/P name=names
o/p name=name

Answer 1

为了使ForEach控制器正常工作，您应该拥有以下变量：

names_1=dentist
names_2=ortho
names_3=cardio

使用Debug Sampler和View Results Tree listener组合进行检查。
