简单搭建http服务器-HttpListener使用

使用HTTPListener能够简单搭建一个Http服务器，对于本地使用非常方面，想起以前使用了WebSocket来与本地网页通信的例子，也是能够改成使用HTTPListener来作的。看下HTTPListener的使用吧。

public class RJHttp
    {
        private HttpListener httpListener = new HttpListener();
        public RJHttp()
        {
            this.httpListener.Prefixes.Add("http://127.0.0.1:8089/");//必须以/结尾
            this.httpListener.Start();
            ///异步等待请求
            this.httpListener.BeginGetContext(this.Read, this.httpListener);
        }
        private void Read(IAsyncResult result)
        {
            ///获取到请求
            HttpListenerContext context = this.httpListener.EndGetContext(result);
            ///获取请求的数据
            HttpListenerRequest request = context.Request;
            string contentType = request.ContentType;
            string httpMethod = request.HttpMethod;
            string userAgent = request.UserAgent;
            StreamReader sr = new StreamReader(request.InputStream);
            string code = sr.ReadToEnd();
            ///返回数据
            byte[] bys = Encoding.UTF8.GetBytes(DateTime.Now.ToString());
            context.Response.OutputStream.Write(bys, 0, bys.Length);
            context.Response.Close();
            this.httpListener.BeginGetContext(this.Read, this.httpListener);
        }
    }

对于请求端使用的什么请求方式能够使用request.HttpMethod的值进行判断，而后返回指定的数据便可。
