如何访问第一位居民的姓名？这是Json文件.以下是什么？
val bigwig = (json \ "residents")(1).....
import play.api.libs.json._
val json: JsValue = Json.parse("""
{
"name" : "Watership Down",
"location" : {
"lat" : 51.235685,
"long" : -1.309197
},
"residents" : [ {
"name" : "Fiver",
"age" : 4,
"role" : null
}, {
"name" : "Bigwig",
"age" : 6,
"role" : "Owsla"
} ]
}
""")
