您好，有人能帮我提取方括号内的值吗。非常感谢您的回复。谢谢，提前

等等

方括号内的值是动态的。我只想在方括号或“[]”内增加所有值

我认为这将更易于使用，相关代码如下所示：

def json = new groovy.json.JsonSlurper().parse(prev.getResponseData())
def counter = 1
json.each { entry ->
    entry.getValue().each { number ->
        vars.put('value_' + counter, number as String)
        counter++
    }
}
