Question

我试图获得距离某个位置20公里范围内最近的解析对象。

  var testPoint = new Parse.GeoPoint({latitude: fromLatLng.lat, longitude: fromLatLng.lng});
  var BKcity = Parse.Object.extend("BKcity");
  var cityQuery = new Parse.Query(BKcity);
  //Throws mongo error
  cityQuery.withinKilometers("location", testPoint, 20);
  cityQuery.find({
  ...

但是查询失败了：

�[31merror�[39m: Uncaught internal server error. { [MongoError: Can't canonicalize query: BadValue geo near accepts just one argument when querying for a GeoJSON point. Extra field found: $maxDistance: 0.003139224611520954]

查询适用于javascript，.near（）查询也可以，但不能在公尺内查询。

这是一个解析服务器错误或mlab问题还是我自己的愚蠢错误？

对此感到抱歉。事实证明，在设置geopoint时我搞砸了将javascript字符串转换为float。
