google maps api返回空结果

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"
}

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,情况与您问题中的url相同,它显示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,我尝试了附近城市边境的Beit Guvrin:

https://maps.googleapis.com/maps/api/geocode/json?address=BeitGuvrin

哪个返回坐标:

"location_type" : "GEOMETRIC_CENTER",
            "viewport" : {
               "northeast" : {
                  "lat" : 32.1298801302915,
                  "lng" : 34.8555745
               },

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,具体取决于API对给定位置的数据量 .
