如何使用groovy將元素添加到json的嵌套元素

Question

我有一些類似於下面的JSON數據，並且想要添加另一個城市名稱。我如何添加它？

我現在的JSON數據如下所示：

{ 
    "state" : "WA", 
    "county" : { 
     "king" : { 
      "Seattle" : [ "r", "d", "n" ], 
      "Kirkland" : [ "r", "d", "w" ] 
     }, 
     "queen" : { 
      "Edmonds" : [ "r" ] 
     } 
    } 
} 

預期JSON數據應該看起來像下面這樣：

{ 
    "state" : "WA", 
    "county" : { 
     "king" : { 
      "Seattle" : [ "r", "d", "n" ], 
      "Kirkland" : [ "r", "d", "w" ] 
     }, 
     "queen" : { 
      "Edmonds" : [ "r" ] 
     } 
     "prince" : { 
      "Lynnwood" : [ "r", "d", "w" ] 
     } 
    } 
} 

Answer 1

你可以從這裏找到答案： - Append json into a json in groovy

Answer 2

使用「將json附加到groovy中的json中」，我能夠使它工作。

import groovy.json.* 

String[] myArray = [ "r", "d", "w" ] 

def builder = new JsonBuilder() 
def root = builder.event{     
    "Lynnwood" myArray 
} 

def json = new JsonSlurper().parseText('''{ "state" : "WA", "county" : { "king" : { "Seattle" : [ "r", "d", "n" ], "Kirkland" : [ "r", "d", "w" ] }, "queen" : { "Edmonds" : [ "r" ] } } }''') 

// Append the built JSON to the "slurped" JSON 
json.county.prince = root.event 

// Re-build the JSON so it can saved as a String 
new JsonBuilder(json).toPrettyString()
