我正在开发一款Android应用程序，使用Google Maps API将位置信息返回为JSON。然而，当我按纬度和经度搜索时，谷歌地图API有时会返回NO结果。为了确保我没有做错什么，我搜索了像这个一样的城市"idhna"
https://maps.googleapis.com/maps/api/geocode/json?address=idhna&key=XXXXXXXXXXXXXXXXXX
它返回
{
"results" : [
{
"address_components" : [
{
"long_name" : "Idhna",
"short_name" : "Idhna",
"types" : [ "locality", "political" ]
}
],
"formatted_address" : "Idhna",
"geometry" : {
"location" : {
"lat" : 31.557252,
"lng" : 34.979243
},
"location_type" : "APPROXIMATE",
"viewport" : {
"northeast" : {
"lat" : 31.5667594,
"lng" : 34.9952504
},
"southwest" : {
"lat" : 31.5477436,
"lng" : 34.9632356
}
}
},
"place_id" : "ChIJjfxiM8TuAhURpQKxXGq5lDo",
"types" : [ "locality", "political" ]
}
],
"status" : "OK"
}
但是当我从结果中复制纬度和经度并尝试搜索时
https://maps.googleapis.com/maps/api/geocode/json?latlng=31.557252,34.979243&key=XXXXXXXXXXXXXXXXXXXXXXXXX
结果是
{
"results" : [],
"status" : "ZERO_RESULTS"
}
这似乎是这个API可以访问的数据的限制，无论您是否获得坐标数据，基本上都是命中或未命中的。
对Sumaya进行测试，结果如下：https://maps.googleapis.com/maps/api/geocode/json?address=sumaya
然而，情况与您问题中的url相同，它没有显示lat/lon:的结果
https://maps.googleapis.com/maps/api/geocode/json?latlng=31.523946，34.968806
作为一个测试，我尝试了附近的边境城市Beit Guvrin：
https://maps.googleapis.com/maps/api/geocode/json?address=BeitGuvrin
返回的坐标：
"location_type" : "GEOMETRIC_CENTER",
"viewport" : {
"northeast" : {
"lat" : 32.1298801302915,
"lng" : 34.8555745
},
它从lat/lon:返回有效结果
https://maps.googleapis.com/maps/api/geocode/json?latlng=32.1298801302915，34.8555745

我还测试了Keidar，它成功地显示了从地址查询返回的坐标的结果。
因此，它基本上是命中或未命中的，这取决于API在给定位置拥有多少数据。
