我是Groovy的新手,正在爲使用Groovy編寫的Smartthing Hub的設備處理程序工作。我無法解析字符串。將字符串注入地圖 - Groovy
def parseDescriptionAsMap(description) {
println "description: '${description}"
def test = description.split(",")
println "test: '${test}"
test.inject([:]) { map, param ->
def nameAndValue = param.split(":")
println "nameAndValue: ${nameAndValue}"
if(map)
{
println "map is NOT NULL"
map.put(nameAndValue[0].trim(),nameAndValue[1].trim())
}
else
{
println "map is NULL!"
}
}
}
輸出:
description: 'index:17, mac:AAA, ip:BBB, port:0058, requestId:ce6598b2-fe8b-463d-bdf3-01ec35055f7a, tempImageKey:ba416127-14e3-4c7b-8f1f-5b4d633102e5
test: '[index:17, mac:AAA, ip:BBB, port:0058, requestId:ce6598b2-fe8b-463d-bdf3-01ec35055f7a, tempImageKey:ba416127-14e3-4c7b-8f1f-5b4d633102e5]
nameAndValue: [index, 17]
nameAndValue: [ mac, AAA]
map is NULL!
nameAndValue: [ ip, BBB]
map is NULL!
map is NULL!
nameAndValue: [ port, 0058]
nameAndValue: [ requestId, ce6598b2-fe8b-463d-bdf3-01ec35055f7a]
兩個問題:
1.爲什麼是可變的,地圖,空?
2.爲什麼函數不打印nameAndValue - >'tempImageKey'info?
