Groovy 将空值发送到 JMeter 请求中

Question

来自上一个请求Groovy脚本正确地将数据保存到 csv 文件中，但在以下请求中传递空值。

不确定到底出了什么问题。尝试对值进行硬编码，请求正常。

https://xx.xx.xx.xxx/xx/projects/2228/week-endings/${__groovy(new%20File('${DH-week-endings}').readLines().get(${counter_value}),)}/departments/${id}/timecards

这是日志中的错误

请看下面的截图

我认为正确的语法应该是这样的：

${__groovy(new File(vars.get('DH-week-endings')).readLines().get(vars.get('counter_value') as int),)}

如果您不确定是否要构建合适的 JMeter 函数 - 请选择 Function Helper Dialog
Since JMeter 3.1 you're supposed to use JSR223 Test Elements and Groovy language for scripting 所以考虑迁移所有剩余的 Beanshell 元素
不要内联 JMeter Functions or Variables into Groovy/Beanshell scripts, go for vars shorthand for JMeterVariables class instance 而是

Groovy 将空值发送到 JMeter 请求中

Groovy sends the empty value into the JMeter Request

groovy

jmeter

beanshell
