本文实例为大家分享了C#实现短信验证码接口示例，供大家参考，具体内容如下

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net.Security; using System.Security.Cryptography.X509Certificates; using System.Net; using System.IO; using System.IO.Compression; using System.Text.RegularExpressions; using System.Security.Cryptography;using System.Web;public class Test{ private static readonly string DefaultUserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)"; private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) { return true; //总是接受 } static void Main(string[] args) { DateTime dt = DateTime.Now; string mttime = dt.ToString("yyyyMMddHHmmss"); string pwd1 = "*************"+mttime; string pwd = GetMD5(pwd1) string content = "【阅信】验证码888888，打死也不能告诉别人哦。"; string url = "http://183.203.28.226:9000/HttpSmsMt"; Encoding encoding = Encoding.GetEncoding("utf-8"); IDictionary<string, string> parameters = new Dictionary<string, string>(); parameters.Add("name", "****"); parameters.Add("pwd", pwd); parameters.Add("content",content); parameters.Add("phone","13381272353"); parameters.Add("subid",""); parameters.Add("mttime", mttime); HttpWebResponse response = CreatePostHttpResponse(url,parameters,encoding); //打印返回值 Stream stream = response.GetResponseStream(); //获取响应的字符串流 StreamReader sr = new StreamReader(stream); //创建一个stream读取流 string html = sr.ReadToEnd(); //从头读到尾，放到字符串html Console.WriteLine(html); } public static string GetMD5(string myString) { MD5 md5 = new MD5CryptoServiceProvider(); // byte[] fromData = System.Web.HttpUtility.UrlEncode.GetBytes(myString); byte[] fromData = Encoding.Default.GetBytes(myString); byte[] targetData = md5.ComputeHash(fromData); string byte2String = null; for(int i=0;i<targetData.Length;i++) { byte2String+= targetData[i].ToString("x"); } return byte2String; } public static HttpWebResponse CreatePostHttpResponse(string url, IDictionary<string, string> parameters,Encoding charset) { HttpWebRequest request = null; //HTTPSQ请求 ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult); request = WebRequest.Create(url) as HttpWebRequest; request.ProtocolVersion = HttpVersion.Version10; request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.UserAgent = DefaultUserAgent; //如果需要POST数据 if (!(parameters == null || parameters.Count == 0)) { StringBuilder buffer = new StringBuilder(); int i = 0; foreach (string key in parameters.Keys) { if (i > 0) { buffer.AppendFormat("&{0}={1}", key, parameters[key]); } else { buffer.AppendFormat("{0}={1}", key, parameters[key]); } i++; } byte[] data = charset.GetBytes(buffer.ToString()); using (Stream stream = request.GetRequestStream()) { stream.Write(data, 0, data.Length); } } return request.GetResponse() as HttpWebResponse; } }
