WebSocket 服务器

首先，你需要先引用这个包 SuperSocket.WebSocket.Server

让我创建这个 WebSocket 服务器，这个服务器将把收到的消息再发送回客户端：

定义命令来处理消息

class ADD : IAsyncCommand<WebSocketSession, StringPackageInfo>
{
    public async ValueTask ExecuteAsync(WebSocketSession session, StringPackageInfo package)
    {
            .Select(p => int.Parse(p))
        await session.SendAsync(result.ToString());
    }
}

注册这个命令

class StringPackageConverter : IPackageMapper<WebSocketPackage, StringPackageInfo>
    {
        var pack = new StringPackageInfo();
        var arr = package.Message.Split(' ', 3, StringSplitOptions.RemoveEmptyEntries);
        pack.Key = arr[0];
        pack.Parameters = arr.Skip(1).ToArray();
        return pack;
}
