WCF服务支持HTTP（get，post）方式请求例子
方式一：
/// <summary> /// Http Get请求 /// </summary> /// <param name="url">请求地址</param> /// <param name="postData">请求参数</param> /// <param name="result">返回结果</param> /// <returns></returns> public static bool WebHttpGet(string url, string postData, out string result) { try { HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url + (postData == "" ? "" : "?") + postData); httpWebRequest.Method = "GET"; httpWebRequest.ContentType = "text/html;charset=UTF-8"; WebResponse webResponse = httpWebRequest.GetResponse(); HttpWebResponse httpWebResponse = (HttpWebResponse)webResponse; System.IO.Stream stream = httpWebResponse.GetResponseStream(); System.IO.StreamReader streamReader = new System.IO.StreamReader(stream, Encoding.GetEncoding("UTF-8")); result = streamReader.ReadToEnd(); //请求返回的数据 streamReader.Close(); stream.Close(); return true; } catch (Exception ex) { result = ex.Message; return false; } } /// <summary> /// Http Post请求 /// </summary> /// <param name="postUrl">请求地址</param> /// <param name="postData">请求参数(json格式请求数据时contentType必须指定为application/json)</param> /// <param name="result">返回结果</param> /// <returns></returns> public static bool WebHttpPost(string postUrl, string postData, out string result, string contentType = "application/x-www-form-urlencoded") { try { byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData); HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(postUrl); httpWebRequest.Method = "POST"; httpWebRequest.ContentType = contentType; httpWebRequest.ContentLength = byteArray.Length; using (System.IO.Stream stream = httpWebRequest.GetRequestStream()) { stream.Write(byteArray, 0, byteArray.Length); //写入参数 } HttpWebResponse httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse; using (System.IO.Stream responseStream = httpWebResponse.GetResponseStream()) { System.IO.StreamReader streamReader = new System.IO.StreamReader(responseStream, Encoding.GetEncoding("UTF-8")); result = streamReader.ReadToEnd(); //请求返回的数据 streamReader.Close(); } return true; } catch (Exception ex) { result = ex.Message; return false; } }
方式二：
/// <summary> /// Http Get请求 /// </summary> /// <param name="url">请求地址</param> /// <param name="postData">请求参数</param> /// <param name="trackId">为防止重复请求实现HTTP幂等性(唯一ID)</param> /// <returns></returns> public static string SendGet(string url, string postData, string trackId) { if (string.IsNullOrEmpty(trackId)) return null; //trackId = Guid.NewGuid().ToString("N"); HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url + (postData == "" ? "" : "?") + postData); httpWebRequest.Method = "GET"; httpWebRequest.ContentType = "text/html;charset=UTF-8"; httpWebRequest.Headers.Add("track_id:" + trackId); WebResponse webResponse = httpWebRequest.GetResponse(); HttpWebResponse httpWebResponse = (HttpWebResponse)webResponse; System.IO.Stream stream = httpWebResponse.GetResponseStream(); System.IO.StreamReader streamReader = new System.IO.StreamReader(stream, Encoding.UTF8); string result = streamReader.ReadToEnd(); //请求返回的数据 streamReader.Close(); stream.Close(); return result; } /// <summary> /// Http Post请求 /// </summary> /// <param name="postUrl">请求地址</param> /// <param name="postData">请求参数(json格式请求数据时contentType必须指定为application/json)</param> /// <param name="trackId">为防止重复请求实现HTTP幂等性(唯一ID)</param> /// <returns></returns> public static string SendPost(string postUrl, string postData, string trackId, string contentType = "application/x-www-form-urlencoded") { if (string.IsNullOrEmpty(trackId)) return null; //trackId = Guid.NewGuid().ToString("N"); byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData); HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(postUrl); httpWebRequest.Method = "POST"; httpWebRequest.ContentType = contentType; httpWebRequest.ContentLength = byteArray.Length; httpWebRequest.Headers.Add("track_id:" + trackId); System.IO.Stream stream = httpWebRequest.GetRequestStream(); stream.Write(byteArray, 0, byteArray.Length); //写入参数 stream.Close(); HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); System.IO.StreamReader streamReader = new System.IO.StreamReader(httpWebResponse.GetResponseStream(), Encoding.UTF8); string result = streamReader.ReadToEnd(); //请求返回的数据 streamReader.Close(); return result; } /// <summary> /// 生成唯一标识符 /// </summary> /// <param name="type">格式：N,D,B,P,X</param> /// <returns></returns> public static string GetGuid(string type = "") { //Guid.NewGuid().ToString(); // 9af7f46a-ea52-4aa3-b8c3-9fd484c2af12 //Guid.NewGuid().ToString("N"); // e0a953c3ee6040eaa9fae2b667060e09 //Guid.NewGuid().ToString("D"); // 9af7f46a-ea52-4aa3-b8c3-9fd484c2af12 //Guid.NewGuid().ToString("B"); // {734fd453-a4f8-4c5d-9c98-3fe2d7079760} //Guid.NewGuid().ToString("P"); // (ade24d16-db0f-40af-8794-1e08e2040df3) //Guid.NewGuid().ToString("X"); // {0x3fa412e3,0x8356,0x428f,{0xaa,0x34,0xb7,0x40,0xda,0xaf,0x45,0x6f}} if (type == "") return Guid.NewGuid().ToString(); else return Guid.NewGuid().ToString(type); }
