Question

鉴于以下JSON，我想提取postal_code（long_name或short_name）。我已经使用JsonSlurper将其摄取到变量中并使用find / contains / etc尝试了各种查询。抓住在“类型”中有“postal_code”但仍无法解决的节点。非常感谢任何帮助。

{
   "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" ]
            },
            {
               "long_name" : "Newport News",
               "short_name" : "Newport News",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Virginia",
               "short_name" : "VA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "23608",
               "short_name" : "23608",
               "types" : [ "postal_code" ]
            }
         ],
         "formatted_address" : "Jefferson Ave & Denbigh Blvd, Newport News, VA 23608, USA",
         "geometry" : {
            "location" : {
               "lat" : 37.13852930,
               "lng" : -76.52013079999999
            },
            "location_type" : "APPROXIMATE",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.13987828029151,
                  "lng" : -76.51878181970848
               },
               "southwest" : {
                  "lat" : 37.13718031970851,
                  "lng" : -76.52147978029149
               }
            }
         },
         "types" : [ "intersection" ]
      }
   ],
   "status" : "OK"
}

以下内容应该找到具有postal_code类型的节点。如果results或address_components有多个列表项，则必须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

Groovy JSON / GPath查询
