android - 为什么 Google Cloud Endpoints 会颠倒我的参数顺序？

Question

我有以下端点方法:

public class PlayerEndpoint {
  private static final String PLAYER_NAME = "player_name";
  private static final String PLAYER_UUID = "player_uuid";

  @ApiMethod(name = "register", httpMethod = ApiMethod.HttpMethod.POST, path="register")
  public Player register(@Named(PLAYER_UUID) String uuid,
                         @Named(PLAYER_NAME) String playerName) {
  log.info(String.format("Registering user uuid: %s name: %s", uuid, playerName));
  ...
  }
}

当我从我的 Android 客户端调用它时:

String uuid = "test_uuid";
String name = "test_name";
playerEndpoint.register(uuid, name).execute();

后端日志:

Registering user uuid: test_name name: test_uuid

这是怎么回事？

我想通了。显然，Endpoints 按字母顺序对您的方法进行排序。

Method parameters in the generated client library are in alphabetical order, regardless of the original order in the backend method. As a result, you should be careful when editing your methods, especially if there are several parameters of the same type. The compiler will not be able to catch parameter-ordering errors for you.
