最近在弄一些第三方的平台，经常调用第三方的接口实现某些特定的功能

在实现的同时基本上都需要本地的数据经过服务器在Request到第三方的服务器中处理，再返回相应的数据结构体：json/xml

以下是我总结的一个小方法，请农友们笑纳：

public static string PostWebReq(string PostUrl, string ParamData, Encoding DataEncode) { string ret = string.Empty; try { byte[] byteArray = DataEncode.GetBytes(ParamData); HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(PostUrl)); webReq.Method = "POST"; webReq.ContentType = "application/x-www-form-urlencoded"; webReq.ContentLength = byteArray.Length; Stream newStream = webReq.GetRequestStream(); newStream.Write(byteArray, 0, byteArray.Length); newStream.Close(); HttpWebResponse response = (HttpWebResponse)webReq.GetResponse(); StreamReader sr = new StreamReader(response.GetResponseStream(), DataEncode); ret = sr.ReadToEnd(); sr.Close(); response.Close(); newStream.Close(); } catch (WebException ex) { Log.WriteLog(LogFile.Error, ex.Message); } finally { Log.WriteLog(LogFile.Info, ret); } return ret; }
