鉴于以下 JSON，我想提取 postal_code（long_name 或 short_name）。我使用 JsonSlurper 将其摄取到变量中，并使用 find/contains/etc 尝试了各种查询。抓取在其“类型”中具有“postal_code”但无法弄清楚的节点。任何帮助是极大的赞赏。

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Jefferson Ave",
               "short_name" : "Jefferson Ave",
               "types" : [ "route" ]
            },
            {
               "long_name" : "North Newport News",
               "short_name" : "North Newport News",
               "types" : [ "neighborhood", "political" ]
            },
            {

下面应该找到 postal_code 类型的节点。如果results或address_components曾经有多个列表项，您将不得不通过用一些迭代替换索引访问来相应地进行调整，但希望这会有所帮助。

import groovy.json.*

def text = '''
{
   "results" : [
<omitted rest to save space>
....
}
'''

def json = new JsonSlurper().parseText(text)

def theNode = json.results[0]
                  .address_components
                  .find { it.types[0] == 'postal_code' }

assert '23608' == theNode.long_name
