我正在尝试使用谷歌 API 提取格式化的地址、纬度、经度。JSON 输出如下所示:
var inpt = {
"results" : [
{
"address_components" : [
{
"long_name" : "94",
"short_name" : "94",
"types" : [ "street_number" ]
},
{
"long_name" : "Kinghorne Street",
"short_name" : "Kinghorne St",
"types" : [ "route" ]
},
{
"long_name" : "Goulburn",
"short_name" : "Goulburn",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Goulburn Mulwaree Council",
"short_name" : "Goulburn Mulwaree",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "New South Wales",
"short_name" : "NSW",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "Australia",
"short_name" : "AU",
"types" : [ "country", "political" ]
},
{
"long_name" : "2580",
"short_name" : "2580",
"types" : [ "postal_code" ]
}
],
"formatted_address" : "94 Kinghorne St, Goulburn NSW 2580, Australia",
"geometry" : {
"location" : {
"lat" : -34.742658,
"lng" : 149.722802
},
"location_type" : "ROOFTOP",
"viewport" : {
"northeast" : {
"lat" : -34.7413090197085,
"lng" : 149.7241509802915
},
"southwest" : {
"lat" : -34.74400698029149,
"lng" : 149.7214530197085
}
}
},
"place_id" : "ChIJ_57nYeiuFmsR0ZLPJl7b2P0",
"plus_code" : {
"compound_code" : "7P4F+W4 Goulburn, New South Wales, Australia",
"global_code" : "4RQF7P4F+W4"
},
"types" : [ "establishment", "food", "point_of_interest", "store" ]
}
],
"status" : "OK"
}
使用 MuleSoft 4 的 Dataweave,我想通过“类型”这是一个数组来过滤有效负载。我的预期结果应该是:
location: "New South Wales"
为了得到上述结果,我尝试了如下表达式:
%dw 2.0
output application/json
--
{
location: inpt.results.address_components filter ($.type contains "administrative_area_level_1")[0]."long_name"
}
但我得到空结果。感谢您的帮助!
超级接近,你的结果是一个数组。如果数组中有多个 JSON 对象,则需要map
它们。这是当前问题的解决方案:
%dw 2.0
output application/json
---
location: (inpt.results[0].address_components filter ($.types contains "administrative_area_level_1"))[0].long_name
