C# 完成WebSocket 服务
相信大家对WebSocket 有所了解，这里就不对WebSocket 进行介绍了 ，直接上菜！
.net core 或 .net 5.0 ,本人用的是 .net 5.0的开发环境，引用下面两个包
本人新建的是窗体控件，窗体代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using WebSocketSharp.Server;
namespace websocket09
{
public partial class Form1 : Form
{
private WebSocketServer wssv;
public Form1()
{
InitializeComponent();
wssv = new WebSocketServer(6690);
}
private void button1_Click(object sender, EventArgs e)
{
wssv.AddWebSocketService
if (wssv.IsListening == true)
{
showMassage("服务已经成功，无需再次启动！");
return;
}
wssv.Start();
showMassage("服务启动成功！");
}
private void button2_Click(object sender, EventArgs e)
{
if (wssv.IsListening == false)
{
showMassage("服务已经关闭，不能发送消息！");
return;
}
var tt = wssv.WebSocketServices.Hosts.ToList();
tt[0].Sessions.SendTo(this.textBox2.Text, tt[0].Sessions.IDs.ToList()[0]);
}
private void button3_Click(object sender, EventArgs e)
{
if (wssv.IsListening == false)
{
showMassage("服务已经关闭，无需再次关闭！");
return;
}
wssv.Stop();
showMassage("服务已经关闭！");
}
//展示获取的消息
public void showMassage(string showstr) {
this.textBox1.Text = this.textBox1.Text + "\r\n" +"获取客户端消息！ " +showstr;
}
}
}
以及新建一个类 add 对应的是，websocket的路径，
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WebSocketSharp;
using WebSocketSharp.Server;
namespace websocket09
{
class Add : WebSocketBehavior
{
protected override void OnOpen()
{
Console.WriteLine("Connection Open");
base.OnOpen();
}
protected override void OnMessage(MessageEventArgs e)
{
var data = e.Data;
//if (TestJson(data))
//{
// var param = JToken.Parse(data);
// if (param["a"] != null && param["b"] != null)
// {
// var a = param["a"].ToObject
// var b = param["b"].ToObject
// Send(JsonConvert.SerializeObject(new { code = 200, msg = "result is " + (a + b) }));
// Task.Factory.StartNew(() => {
// Task.Delay(10000).Wait();
// Send(JsonConvert.SerializeObject(new { code = 200, msg = "I just to tell you, the connection is different from http, i still alive and could send message to you." }));
// });
// }
//}
//else
//{
// Send(JsonConvert.SerializeObject(new { code = 400, msg = "request is not a json string." }));
//}
}
protected override void OnClose(CloseEventArgs e)
{
Console.WriteLine("Connection Closed");
base.OnClose(e);
}
protected override void OnError(ErrorEventArgs e)
{
//Console.WriteLine("Error: " + e.Message);
base.OnError(e);
}
private static bool TestJson(string json)
{
try
{
JToken.Parse(json);
return true;
}
catch (JsonReaderException ex)
{
Console.WriteLine(ex);
return false;
}
}
}
}
通过上面代码添加对应的路径信息，然后书写webscket前端对应的代码，如下：
