使用Groovy仅从JSON对象中获取键 [英] Fetch only keys from JSON Object using groovy

问题描述

这是我的JSON对象

{
"master": {
   "node": "xyz", 
   "files": [{"type": "modified", "file": "test.txt"}]
   }, 
"testbranch2": {
   "node": "abc", 
   "files": [{"type": "modified", "file": "test.txt"}] 
   }, 
"testbranch": {
   "node": "xxx", 
   "files": [{"type": "modified", "file": "test.txt"}], 
   }
}

我只需要对象键名，例如"master"，"testbranch2"，"testbranch".如何使用Groovy仅获取对象键名?

I need only the object key names, like "master", "testbranch2","testbranch. How do I fetch only the object key names using groovy?

推荐答案

您可以使用JsonSlurper

You can use JsonSlurper

import groovy.json.JsonSlurper

def json =  '{ "master": ...'
def test = new JsonSlurper().parseText(json)
//if json comes from file you can do: new JsonSlurper().parse(new File('YOUR_JSON_FILE'))
println test.keySet()
