Given the following JSON, I would like to extract the postal_code (either long_name or short_name). I've used JsonSlurper to ingest it into a variable and have tried various queries using find/contains/etc. to grab the node that has "postal_code" in its "types" but haven't been able to figure it out. Any help is greatly appreciated.
{
"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"
}
Answer
The following should find the node with a postal_code type. If the results or address_components ever have multiple list items you would have to adjust accordingly by replacing the indexed access with some iteration, but hopefully this helps.
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
