结合Google地图API可以很好地工作,例如使用以下API从地址获取位置。
地址为“Mountain View, CA, US”。
https://maps.googleapis.com/maps/api/geocode/json?address=Mountain+View,+CA,+US&key=YOUR_API_KEY
此URL返回JSON,类似于以下内容:
{
"results" : [
{
"address_components" : [
{
"long_name" : "Mountain View",
"short_name" : "Mountain View",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Santa Clara County",
"short_name" : "Santa Clara County",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "California",
"short_name" : "CA",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "United States",
"short_name" : "US",
"types" : [ "country", "political" ]
},
{
"long_name" : "94043",
"short_name" : "94043",
"types" : [ "postal_code" ]
}
],
"formatted_address" : "Mountain View, CA 94043, USA",
"geometry" : {
"location" : {
"lat" : 37.4224764,
"lng" : -122.0842499
},
"location_type" : "GEOMETRIC_CENTER",
"viewport" : {
"northeast" : {
"lat" : 37.4238253802915,
"lng" : -122.0829009197085
},
"southwest" : {
"lat" : 37.4211274197085,
"lng" : -122.0855988802915
}
}
},
"place_id" : "ChIJ2eUgeAK6j4ARbn5u_wAGqWA",
"types" : [ "street_address" ]
}
],
"status" : "OK"
}
你可以从JSON中提取位置信息并调用时区API来获取时区。
API调用示例:
https://maps.googleapis.com/maps/api/timezone/json?location=39.6034810,-119.6822510×tamp=1331161200&key=YOUR_API_KEY
返回类似以下的JSON:
{
"dstOffset" : 0,
"rawOffset" : -28800,
"status" : "OK",
"timeZoneId" : "America/Los_Angeles",
"timeZoneName" : "Pacific Standard Time"
}
