使用Groovy将json附加到现有的json文件中

@Grab('org.codehaus.groovy:groovy-json:2.5.13')
import groovy.json.JsonSlurper
import groovy.json.JsonOutput

def existingJson = new File('path/to/existing.json').text
def jsonSlurper = new JsonSlurper()
def existingData = jsonSlurper.parseText(existingJson)

def newData = [
    "key1": "value1",
    "key2": "value2"
]

existingData << newData

def updatedJson = JsonOutput.toJson(existingData)

new File('path/to/existing.json').text = updatedJson
