C# 控制台或者winform程序开启http的监听状态

  1 public class THttpListener  2     {  3         HttpListener listerner;  4         /// <summary>  5         ///   6         /// </summary>  7         /// <param name="PRefixes">格式 http://*/test/ </param>  8         /// <param name="authent"></param>  9         public THttpListener(string[] prefixes, AuthenticationSchemes authent = AuthenticationSchemes.Anonymous) 10         { 11             listerner = new HttpListener(); 12             listerner.AuthenticationSchemes = authent;//指定身份验证 Anonymous匿名访问 13             foreach (var item in prefixes) 14             { 15                 listerner.Prefixes.Add(item); 16                 Console.WriteLine(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss") + " : HttpListener：" + item); 17             } 18         } 19  20         public delegate void ResponseEventArges(HttpListenerContext ctx); 21         public event ResponseEventArges ResponseEvent; 22         AsyncCallback ac = null; 23  24         public void Start() 25         { 26             if (!listerner.IsListening) 27             { 28                 listerner.Start(); 29                 ac = new AsyncCallback(GetContextAsyncCallback); 30                 listerner.BeginGetContext(ac, null); 31                 Console.WriteLine(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss") + " : Start"); 32             } 33         } 34  35         /// <summary> 36         /// 停止监听服务 37         /// </summary> 38         public void Stop() 39         { 40             listerner.Stop(); 41         } 42  43         /// <summary> 44         /// 收到监听请求回调 45         /// </summary> 46         /// <param name="ia"></param> 47         public void GetContextAsyncCallback(IAsyncResult ia) 48         { 49             if (ia.IsCompleted) 50             { 51                 var ctx = listerner.EndGetContext(ia); 52                 ctx.Response.StatusCode = 200; 53                 if (ResponseEvent != null) 54                 { 55                     ResponseEvent.BeginInvoke(ctx, null, null); 56                 } 57                 else 58                 { 59                     System.IO.BinaryWriter br = new System.IO.BinaryWriter(ctx.Response.OutputStream, new UTF8Encoding()); 60                     br.Write("error: 服务器未处理"); 61                     ctx.Response.Close(); 62                     br.Close(); 63                     br.Dispose(); 64                 } 65             } 66             listerner.BeginGetContext(ac, null); 67         } 68  69         public Dictionary<string, string> getData(System.Net.HttpListenerContext ctx) 70         { 71             var request = ctx.Request; 72             if (request.HttpMethod == "GET") 73             { 74                 return getData(ctx, DataType.Get); 75             } 76             else  77             { 78                 return getData(ctx, DataType.Post); 79             } 80         } 81  82         public Dictionary<string, string> getData(System.Net.HttpListenerContext ctx, DataType type) 83         { 84             var rets = new Dictionary<string, string>(); 85             var request = ctx.Request; 86             switch (type) 87             { 88                 case DataType.Post: 89                     if (request.HttpMethod == "POST") 90                     { 91                         string rawData; 92                         using (var reader = new StreamReader(request.InputStream, request.ContentEncoding)) 93                         { 94                             rawData = reader.ReadToEnd(); 95                         } 96                         string[] rawParams = rawData.Split('&'); 97                         foreach (string param in rawParams) 98                         { 99                             string[] kvPair = param.Split('=');100                             string key = kvPair[0];101                             string value = HttpUtility.UrlDecode(kvPair[1]);102                             rets[key] = value;103                         }104                     }105                     break;106                 case DataType.Get:107                     if (request.HttpMethod == "GET")108                     {109                         string[] keys = request.QueryString.AllKeys;110                         foreach (string key in keys)111                         {112                             rets[key] = request.QueryString[key];113                         }114                     }115                     break;116             }117             return rets;118         }119 120         /// <summary>121         /// 数据提交方式122         /// </summary>123         public enum DataType124         {125             Post,126             Get,127         }128         129         130     }

测试调用类

 1 public class TestHttp 2     { 3         THttpListener _HttpListener; 4         public TestHttp() 5         { 6             string[] strUrl = new string[] { "http://*/Test/" }; 7             _HttpListener = new THttpListener(strUrl); 8             _HttpListener.ResponseEvent += _HttpListener_ResponseEvent; 9             _HttpListener.Start();10         }11 12         void _HttpListener_ResponseEvent(System.Net.HttpListenerContext ctx)13         {14             //直接获取数据15             Dictionary<string, string> rets = _HttpListener.getData(ctx);16             //获取get数据17             Dictionary<string, string> retGets = _HttpListener.getData(ctx, THttpListener.DataType.Get);18             //获取post数据19             Dictionary<string, string> retPosts = _HttpListener.getData(ctx, THttpListener.DataType.Post);20             ResponseWrite(ctx.Request.AcceptTypes[0], "Ret", ctx.Response);21         }22 23         static void ResponseWrite(string type, string msg, System.Net.HttpListenerResponse response)24         {25             //使用Writer输出http响应代码26             using (System.IO.StreamWriter writer = new System.IO.StreamWriter(response.OutputStream, new UTF8Encoding()))27             {28                 response.ContentType = type + ";charset=utf-8";29                 writer.WriteLine(msg);30                 writer.Close();31                 response.Close();32             }33         }34     }

当我们在服务程序或者后台程序需要开启对http的监听，来获取提交数据，但是又不能web服务器来挂在的程序，
