我正在使用Google Maps API处理Android应用，将位置信息作为JSON返回。但是，当我按纬度和经度搜索时，Google Maps API有时会返回NO结果。为了确保我没有做错事，我搜索了像这样的城市“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"
}
答案 0 :(得分：0)
看起来这是此API可以访问的数据的限制，并且无论您是否获得坐标数据，它基本上都会受到影响。
测试Sumaya，它显示结果： https://maps.googleapis.com/maps/api/geocode/json?address=sumaya
但是，情况与你问题中的网址相同，它显示的是lat / lon没有结果：
https://maps.googleapis.com/maps/api/geocode/json?latlng=31.523946,34.968806
就像测试一样，我尝试了附近城市Beit Guvrin的边界：
https://maps.googleapis.com/maps/api/geocode/json?address=BeitGuvrin
返回的坐标是什么：
"location_type" : "GEOMETRIC_CENTER",
"viewport" : {
"northeast" : {
"lat" : 32.1298801302915,
"lng" : 34.8555745
},
返回lat / lon的有效结果：
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，具体取决于API对给定位置的数据量。
