C# WebSocket简单使用

前言

最近接到了一个需求，需要网页实现上位机的功能。那就对数据传输的实时性要求很高。那就只能用WebSocket了。这里简单说一下我的WebSocket如何搭建

Fleck

C# WebSocket(Fleck) 客户端:html Winfrom

Fleck Github官网

我这里用的Fleck去做Websocket。如果有更好的Websocket包可以评论区说一下。

调试工具

这里推荐使用PostMan，自己

初始化

这样太简单了，我们需要对他进行简单封装一下

{public class OutPartail_PRPD_Service{public List<IWebSocketConnection> Connections { get; set; }public WebSocketServer WebSocketServer { get; set; }public OutPartail_PRPD_Service(){Connections = new List<IWebSocketConnection>();WebSocketServer = new WebSocketServer("ws://0.0.0.0:7081");WebSocketServer.Start(socket =>{socket.OnOpen = () =>{PrintMsg("客户端连接成功!");Connections.Add(socket);PrintMsg("当前客户端数量：" + Connections.ToList().Count);};socket.OnClose = () =>{PrintMsg("客户端已经关闭!");Connections.Remove(socket);PrintMsg("当前客户端数量：" + Connections.ToList().Count);};socket.OnError = (e) =>{PrintMsg("客户端运行遇到问题");PrintMsg(e.ToString());};//收到消息时socket.OnMessage = message =>{PrintMsg($"接收到[{socket.ConnectionInfo.Id}]信息:{message}");socket.Send(message);};});}//打印数据private void PrintMsg(string msg){Console.WriteLine($"{SocketName}:{msg}");}//向所有已连接的对象发送数据public void SendMsg(string msg){foreach (var item in Connections){item.Send(msg);}}
}

简单使用

/// <summary>
/// Sim卡切换
/// </summary>
/// <param name="index"></param>
public async Task ChangeSimNo(int index)
{int row = (index / 12);string col = Convert.ToInt32(index % 12).ToString("X1");var msg = $"AT+S{row}{col}";SimNo = -1;Send(msg);try{var res = await Recive(waitTime);ShowMsg(res);res = await Recive(waitTime);if (res.Contains("OK")){SimNo = index;ShowMsg($"Sim[{index}]卡切换成功！");}else{ShowMsg($"Sim[{index}]卡接受报文错误，应为OK！");}}catch (Exception ex){throw new Exception("等待OK超时");}}
