為了個人信息的安全，很多網站都有短信發送的功能，究竟是怎么實現的呢？對于個人站長來說的話，通過使用SMS短信通API接口相對比較劃算和簡單。那怎么實現呢，步驟如下：

1. 從網上（http://sms.webchinese.cn/）申請賬號，記住用戶名，密碼會發到手機上，這僅是登陸密碼。注冊后會送5條短信、和3條彩信的發送量。

2.查看SMS短信通API下行接口（http://sms.webchinese.cn/api.shtml），然后獲取秘鑰，其實就是加密后的登錄密碼。開始敲代碼，相關代碼如下：

using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Net;using System.Text;using System.Web;namespace Y_PostSms{  public class YMethod  {    private string THE_UID = ""; //用戶名    private string THE_KEY = ""; //接口秘鑰    /// <summary>返回UTF-8編碼發送接口地址</summary>    /// <param name="receivePhoneNumber">目的手機號碼（多個手機號請用半角逗號隔開）</param>    /// <param name="receiveSms">短信內容，最多支持400個字，普通短信70個字/條，長短信64個字/條計費</param>    /// <returns></returns>    public string GetPostUrl(string smsMob, string smsText)    {      string postUrl = "http://utf8.sms.webchinese.cn/?Uid=" + THE_UID + "&key=" + THE_KEY + "&smsMob=" + smsMob + "&smsText=" + smsText;      return postUrl;    }    /// <summary> 發送短信，得到返回值</summary>    public string PostSmsInfo(string url)    {      //調用時只需要把拼成的URL傳給該函數即可。判斷返回值即可      string strRet = null;      if (url == null || url.Trim().ToString() == "")      {        return strRet;      }      string targeturl = url.Trim().ToString();      try      {        HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(targeturl);        hr.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";        hr.Method = "GET";        hr.Timeout = 30 * 60 * 1000;        WebResponse hs = hr.GetResponse();        Stream sr = hs.GetResponseStream();        StreamReader ser = new StreamReader(sr, Encoding.Default);        strRet = ser.ReadToEnd();      }      catch (Exception ex)      {        strRet = null;      }      return strRet;    }    /// <summary>確認返回信息 </summary>    public string GetResult(string strRet)    {      int result = 0;      try      {        result = int.Parse(strRet);        switch (result)        {          case -1:            strRet = "沒有該用戶賬戶";            break;          case -2:            strRet = "接口密鑰不正確,不是賬戶登陸密碼";            break;          case -21:            strRet = "MD5接口密鑰加密不正確";            break;          case -3:            strRet = "短信數量不足";            break;          case -11:            strRet = "該用戶被禁用";            break;          case -14:            strRet = "短信內容出現非法字符";            break;          case -4:            strRet = "手機號格式不正確";            break;          case -41:            strRet = "手機號碼為空";            break;          case -42:            strRet = "短信內容為空";            break;          case -51:            strRet = "短信簽名格式不正確,接口簽名格式為：【簽名內容】";            break;          case -6:            strRet = "IP限制";            break;          default:            strRet = "發送短信數量：" + result;            break;        }      }      catch (Exception ex)      {        strRet = ex.Message;      }      return strRet;    }  }}

3. 找在線客服開通發送權限，填寫好簽名，效果圖如下：
