本文介绍了一个使用C#进行HTTP POST请求的具体示例。通过该示例，读者可以了解到如何构建POST请求、设置请求头信息及处理响应数据。特别地，示例展示了如何将XML数据作为请求体发送。

Program.cs 控制台程序

（xml也可改成key1=value1&key2=value2的形式）

using System; using System.Collections.Generic; using System.Text; using System.Net; using System.IO; namespace Example20 { class Program { static void Main(string[] args) { // Post XML string url2 = "http://www.bizsms.cn/InterFace/InterFace.php"; string xml = "<?xml version='1.0' encoding='UTF-8'?><ROOT><MDL>TIMESTAMP</MDL><ACT>GET</ACT></ROOT>"; // 或 Key = Value 方式 Console.WriteLine(PostData(url2, xml)); Console.ReadKey(); } public static string PostData(string purl, string str) { try { byte[] data = System.Text.Encoding.GetEncoding("GB2312").GetBytes(str); // 准备请求 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(purl); //设置超时 req.Timeout = 30000; req.Method = "Post"; req.ContentType = "application/x-www-form-urlencoded"; req.ContentLength = data.Length; Stream stream = req.GetRequestStream(); // 发送数据 stream.Write(data, 0, data.Length); stream.Close(); HttpWebResponse rep = (HttpWebResponse)req.GetResponse(); Stream receiveStream = rep.GetResponseStream(); Encoding encode = System.Text.Encoding.GetEncoding("UTF-8"); // Pipes the stream to a higher level stream reader with the required encoding format. StreamReader readStream = new StreamReader(receiveStream, encode); Char[] read = new Char[256]; int count = readStream.Read(read, 0, 256); StringBuilder sb = new StringBuilder(""); while (count > 0) { String readstr = new String(read, 0, count); sb.Append(readstr); count = readStream.Read(read, 0, 256); } rep.Close(); readStream.Close(); return sb.ToString(); } catch (Exception ex) { return ""; // ForumExceptions.Log(ex); } } } }
