我需要形成这个:
{
“item” : “hardcoded_value”,
“item2” : “hardcoded_value”,
“item3” : “hardcoded_value”,
}
在我正在尝试的exec块中:
// list with items [“item1”, “ item2”, “ item3”]
val theList = session("itemNames").as[List[String]]
val theMap = Map.empty[String,String] // empty map
// add items from list in map
theList.foreach{ key =>
| theMap += key -> "hardcoded_value"
}
但是在+ =位置得到错误。
也尝试过:
theList.foreach(key => theMap += key -> "hardcoded_value" )
如何通过迭代列表将键和值插入到地图中?我是gatling和scala的新手。

在更详细地查看您的问题之后,我意识到您不只是要求将集合转换为地图。结合How can I use map and receive an index as well in Scala?和Scala best way of turning a Collection into a Map-by-key?的答案,您可以执行以下操作:
List("first", "second", "third").zipWithIndex.map {
case (item, index) => ("item" + index) -> item.toString
}
>res0: List[(String, String)] = List((item0,first), (item1,second), (item2,third))
