可通过网页直接访问。

程序访问方法

string httpUrl = System.Configuration.ConfigurationManager.AppSettings["url"];// http://localhost:8820/

            WebRequest webRequest = WebRequest.Create(httpUrl);

            webRequest.ContentType = "text/xml; charset=utf-8";

            webRequest.Method = "POST";

            string responseString = string.Format("<HTML><BODY> {0}</BODY></HTML>", DateTime.Now);

            //byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);

            using (Stream requestStream = webRequest.GetRequestStream())

            {

                byte[] paramBytes = Encoding.UTF8.GetBytes(responseString);

                requestStream.Write(paramBytes, , paramBytes.Length);

            }

            //响应

            WebResponse webResponse = webRequest.GetResponse();

            using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))

            {

                string result = "";

                result = myStreamReader.ReadToEnd();

            }

JSON数据传输方法

//data未数据对象

string str = JsonConvert.SerializeObject(data);

string res = Post(httpUrl, str);

 public static string Post(string url, string json)

        {

            string st;

            try

            {

                HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; //创建请求

                CookieContainer cookieContainer = new CookieContainer();

                request.CookieContainer = cookieContainer;

                request.Method = "POST"; //请求方式为post

                request.AllowAutoRedirect = true;

                request.MaximumResponseHeadersLength = ;

                request.ContentType = "application/json";

                //request.ContentType = "text/xml; charset=utf-8";

                byte[] jsonbyte = Encoding.UTF8.GetBytes(json);

                Stream postStream = request.GetRequestStream();

                postStream.Write(jsonbyte, , jsonbyte.Length);

                postStream.Close();

                //发送请求并获取相应回应数据

                HttpWebResponse res = (HttpWebResponse)request.GetResponse();

                StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.UTF8);

                st = sr.ReadToEnd();

            }

            catch (WebException ex)

            {

                //Log4netHelper.WriteErrorLog(url, ex);

                st = null;

            }

            return st;

        }
