Google warns us关于PlaceID的更改和建议;


  地方ID可能会由于Google Maps数据库上的大规模更新而发生变化。在这种情况下,一个地方可能会收到一个新的地方ID,而旧的ID会返回NOT_FOUND响应。
  
  您可以通过发出场所详细信息请求,仅在fields参数中指定ID字段来免费刷新场所ID。


不幸的是,除了指向他们的web services的链接之外,他们的网站上没有Java / Kotlin的示例代码。

字符串placeID =“ Some place ID”;

    List<Place.Field> placeFields = Arrays.asList(
            Place.Field.ID,
    );

    // Construct a request object, passing the place ID and fields array.
    FetchPlaceRequest request = FetchPlaceRequest.builder(placeID, placeFields).build();
    placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
        Place place = response.getPlace();

        if (!placeID.equals(place.getId())) {
            //update your old placeID
        }
   }).addOnFailureListener((exception) -> {
        if (exception instanceof ApiException) {
            //Place removed.
        }
   });


这是使用Java更新placeID的简便方法吗?

最佳答案

我已经测试了数据库,并发现了发生更新的情况。以下代码包含更新的placeID,已删除的placeID和仍然有效的palceID,以便可以进行测试。

ArrayList<String> placeIDsList = new ArrayList<>();
placeIDsList.add("ChIJTaKjynxesBQREvi1CU5QUFg");
placeIDsList.add("EjhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg");
placeIDsList.add("hIJy9YVxdxpsBQRq0-xUVJdZQ8");

// Specify the fields to return (in this example all fields are returned).
List<Place.Field> placeFields = Arrays.asList(Place.Field.ID);

for (String plc : placeIDsList ) {
    // Construct a request object, passing the place ID and fields array.
    FetchPlaceRequest request = FetchPlaceRequest.builder(plc, placeFields).build();

    Log.e(TAG,"request for place with ID = " + plc);

    placesClient.fetchPlace(request).addOnSuccessListener((response) -> {
        Place place = response.getPlace();


        if (!plc.equals(place.getId())) {
            Log.e(TAG,"placeID renewed");
            Log.e(TAG,"placeID old = " + plc);
            Log.e(TAG,"placeID new = " + place.getId());

        } else {
            Log.e(TAG, "Place found: " + place.getId());
        }


    }).addOnFailureListener((exception) -> {
        if (exception instanceof ApiException) {
            ApiException apiException = (ApiException) exception;
            int statusCode = apiException.getStatusCode();
            // Handle error with given status code.
            Log.e(TAG, "Place with ID "+plc+" not found");
            Log.e(TAG, "Exception message is :" + exception.getMessage());
            Log.e(TAG, "Status code = " + statusCode);
        }
    });
}


输出是

E/MapsActivity: request for place with ID = ChIJTaKjynxesBQREvi1CU5QUFg
E/MapsActivity: request for place with ID = jhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg
E/MapsActivity: request for place with ID = hIJy9YVxdxpsBQRq0-xUVJdZQ8
E/MapsActivity: placeID renewed
E/MapsActivity: placeID old = EjhDdW1odXJpeWV0IE1haGFsbGVzaSwgVXp1biBTay4sIEV6aW5lL8OHYW5ha2thbGUsIFR1cmtleSIuKiwKFAoSCakQkmN8XrAUEVkLpNK_F4IJEhQKEgmFzKyYe16wFBGSjU7F2ooIIg

E/MapsActivity: Place with ID hIJy9YVxdxpsBQRq0-xUVJdZQ8 not found
E/MapsActivity: Exception message is :9012: INVALID_REQUEST
E/MapsActivity: Status code = 9012
E/MapsActivity: Place found: ChIJTaKjynxesBQREvi1CU5QUFg


看来status code 9102是找不到的地方。
