HttpLitener处理http请求和Websocket请求的案例具体步骤如下

1、新建控制台项目TestClientWebsocket

 

 

2、选择项目右键添加类HttpAndWebsocket，代码如下

using System;

using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.WebSockets; using System.Text; using System.Threading; using System.Threading.Tasks;

namespace TestClientWebsocket

{ public class HttpAndWebsocket { public async void Start(string url) { string url1 = "http://+:80/"; int Port = 1234; HttpListener httpListener = new HttpListener(); httpListener.Prefixes.Add("http://+:" + Port + "/");//注：其中//和：之间的+是代表本机的所有ip httpListener.Start(); while (true) { try { HttpListenerContext httpListenerContext = await httpListener.GetContextAsync(); try { if (httpListenerContext.Request.IsWebSocketRequest) { ProcessRequest(httpListenerContext); } } catch (Exception) { httpListenerContext.Response.StatusCode = 400; httpListenerContext.Response.Close(); } } catch (Exception) { throw; } } }

private async void ProcessRequest(HttpListenerContext listenerContext)

{ HttpListenerWebSocketContext httpListenerWebSocket;

try

{ httpListenerWebSocket = await listenerContext.AcceptWebSocketAsync(null); } catch (Exception) { listenerContext.Response.StatusCode = 500; listenerContext.Response.Close(); return; } WebSocket webSocket = httpListenerWebSocket.WebSocket; try {

while (webSocket.State == WebSocketState.Open)

{ byte[] returnBytes = new byte[10240]; WebSocketReceiveResult webSocketReceiveResult = await webSocket.ReceiveAsync(new ArraySegment<byte>(returnBytes), CancellationToken.None); string ReceivesData = Encoding.UTF8.GetString(returnBytes, 0, webSocketReceiveResult.Count); ReceivesData = $"我已经收到数据：{ReceivesData}"; returnBytes = Encoding.UTF8.GetBytes(ReceivesData); await webSocket.SendAsync(new ArraySegment<byte>(returnBytes), WebSocketMessageType.Text, true, CancellationToken.None); await Task.Delay(TimeSpan.FromSeconds(3)); } } catch (Exception) {

throw;

} finally { if (webSocket != null) { webSocket.Dispose(); } } }

}

}

 

4、控制台的Program.cs中代码

using System;

using System.Collections.Generic; using System.IO; using System.Linq; using System.Net.WebSockets; using System.Text; using System.Threading; using System.Threading.Tasks;

namespace TestClientWebsocket

{ class Program { public static string SocketUrl = "ws://127.0.0.1:1234/"; //public static string SocketUrl = "ws://192.168.1.202:8081/ws?id=";

static void Main(string[] args)

{

//启动Websocket服务

HttpAndWebsocket httpAndWebsocket = new HttpAndWebsocket(); httpAndWebsocket.Start(SocketUrl);

//启动ClientWebsocket客户端

for (int i = 0; i < 2; i++)

{

System.Threading.Tasks.Task.Factory.StartNew(BBB, i);

}

Console.WriteLine("Press ENTER to exit..."); Console.ReadLine();

//string name = Console.ReadLine();

//string no = Console.ReadLine(); //string level = Console.ReadLine(); //string imagestring = Console.ReadLine(); //string returnvalue = Login(name, no, level, imagestring).Result; //string returnvalue = Login("22", "22", "22", "22").Result;

//for (int i = 0; i < 2; i++)

//{ // //System.Threading.Thread.Sleep(TimeSpan.FromSeconds(5));

// //System.Threading.Tasks.Task.Factory.StartNew(BBB, i);

// Task.Delay(2000); // TestWebsocket testWebsocket = new TestWebsocket("ws://127.0.0.1:1234/", i.ToString(), "1", "1", "1"); // testWebsocket.showmeg = Addlog; // testWebsocket.Satart();

//}

//System.Threading.Tasks.Task.Factory.StartNew(BBB, 66); //Console.WriteLine($"{returnvalue}"); //returnvalue = Login("33", "33", "33", "33").Result; //Console.WriteLine($"{returnvalue}"); Console.Read();

//string returnvalue = TestWebsocket.EvaluateWithReasons().Result;

//string returnvalue = TestWebsocket.FaceValidateWithIdCard().Result;

}

public static async void BBB(object i)

{ string x = $"这是第{i}个。。。"; //ClientWebSocket cln = new ClientWebSocket(); //cln.ConnectAsync(new Uri(SocketUrl), new CancellationToken()).Wait(); //byte[] bytess = Encoding.Default.GetBytes($"111"); //cln.SendAsync(new ArraySegment<byte>(bytess), WebSocketMessageType.Text, true, new CancellationToken()).Wait(); //string returnValue = await GetAsyncValue(cln);//异步方法 //Console.WriteLine($"{returnValue}"); try { ClientWebSocket cln = new ClientWebSocket(); await cln.ConnectAsync(new Uri(SocketUrl + i.ToString()), new CancellationToken()); string returnvalue = await Login(cln, "1", "1", "1", "1"); Console.WriteLine($"{returnvalue}");

//string returnvalue = await TestClientWebsocket.TestWebsocket.Login("1", "1", "1", "1");

//Console.WriteLine($"{returnvalue}"); } catch (Exception ex) { throw ex; }

}

public static async Task<string> Login(ClientWebSocket cln, string name, string no, string level, string imagestring)

{ byte[] bytess = Encoding.Default.GetBytes($"login#{name}#{no}#{level}#{imagestring}"); await cln.SendAsync(new ArraySegment<byte>(bytess), WebSocketMessageType.Text, true, new CancellationToken()); string returnValue = await GetAsyncValue(cln);//异步方法 return returnValue; }

public static async Task<string> GetAsyncValue(ClientWebSocket clientWebSocket)

{ string returnValue = null; byte[] buffer = new byte[10240]; WebSocketReceiveResult result = null; //while (clientWebSocket.State == WebSocketState.Open) //{ result = await clientWebSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None); if (result.MessageType == WebSocketMessageType.Text) { returnValue = Encoding.UTF8.GetString(buffer, 0, result.Count); Console.WriteLine(returnValue); }  return returnValue; } } }
