我正在为迷宫游戏创建一个 ASP.Net Web API 服务。
- 用户应获取迷宫中的所有单元格详细信息，以在 2D 平面中可视化迷宫。我正在使用 get 方法实现这一点
public List<Cell> Get() - 用户应该通过将 CellID 作为输入来获取单元格的详细信息。我正在使用 get 方法实现这一点
public CellRepresentation Get(string id)。请注意，CellRepresentation 用于使用WebApi.Hal返回超媒体链接。这些链接代表可能移动的目标单元格，如上、下、左和右。
现在，我需要一种方法来向用户传达启动游戏的起始单元格。[在下面的迷宫中，单元格“10”是起点]。发送此消息的基于 REST 的方式是什么？
