gmap api geocode zipcode saudi arabia 未按预期工作

Question

使用 Google 地图 API 获取邮政编码的边界和坐标。

在对沙特阿拉伯 (SA) 区域的地址进行地理编码时，当对沙特阿拉伯 (SA) 的邮政编码进行地理编码时，地理编码器的结果具有指向 2517 荷兰海牙的地址

由于结果与沙特阿拉伯无关，在api中添加了国家限制。但结果有 Partial Results 值 True，指的是结果不准确，结果有只有沙特阿拉伯位置的默认值

            },
            "location_type" : "APPROXIMATE",
            "viewport" : {

               "southwest" : {
                  "lat" : 16.379528,
                  "lng" : 34.5489978
               }
            }
         },
         "partial_match" : true,

         "types" : [ "country", "political" ]
      }
   ],
   "status" : "OK"
}

但是当 Street/Region 的地址添加了 Zipcode 时，地理编码就起作用了 https://maps.googleapis.com/maps/api/geocode/json?address=2517+Ar+Riyadh&components=country:SA

有没有办法强制 Gmap api 对沙特阿拉伯国家/地区唯一具有邮政编码的地址进行地理编码，结果是准确的坐标和边界？
