谷歌地图 api 返回空结果

Question

我正在开发一个使用 Google Maps API 以 JSON 格式返回位置信息的 Android 应用程序。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什么，我像这样搜索了城市“idhna”

https://maps.googleapis.com/maps/api/geocode/json?address=idhna&key=XXXXXXXXXXXXXXXXXX

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经纬度并尝试搜索时

https://maps.googleapis.com/maps/api/geocode/json?latlng=31.557252,34.979243&key=XXXXXXXXXXXXXXXXXXXXXXXXX

结果是

{
   "results" : [],
   "status" : "ZERO_RESULTS"
}

Answer 1

看起来这是此 API 可以访问的数据的限制，无论您获取坐标数据，它基本上都是命中或错过。

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，它没有显示 lat/lon 的结果：

https://maps.googleapis.com/maps/api/geocode/json?latlng=31.523946,34.968806

作为测试，我尝试了附近的边境城市Beit Guvrin：

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

返回坐标：

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

从纬度/经度返回有效结果：

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 对给定位置有多少数据。
