为了个人信息的安全，很多网站都有短信发送的功能，究竟是怎么实现的呢？对于个人站长来说的话，通过使用SMS短信通API接口相对比较划算和简单。那怎么实现呢，步骤如下：

1. 从网上（http://sms.webchinese.cn/）申请账号，记住用户名，密码会发到手机上，这仅是登陆密码。注册后会送5条短信、和3条彩信的发送量。

2.查看SMS短信通API下行接口（http://sms.webchinese.cn/api.shtml），然后获取秘钥，其实就是加密后的登录密码。开始敲代码，相关代码如下：

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 = ""; //用户名    private string THE_KEY = ""; //接口秘钥    /// <summary>返回UTF-8编码发送接口地址</summary>    /// <param name="receivePhoneNumber">目的手机号码（多个手机号请用半角逗号隔开）</param>    /// <param name="receiveSms">短信内容，最多支持400个字，普通短信70个字/条，长短信64个字/条计费</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> 发送短信，得到返回值</summary>    public string PostSmsInfo(string url)    {      //调用时只需要把拼成的URL传给该函数即可。判断返回值即可      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>确认返回信息 </summary>    public string GetResult(string strRet)    {      int result = 0;      try      {        result = int.Parse(strRet);        switch (result)        {          case -1:            strRet = "没有该用户账户";            break;          case -2:            strRet = "接口密钥不正确,不是账户登陆密码";            break;          case -21:            strRet = "MD5接口密钥加密不正确";            break;          case -3:            strRet = "短信数量不足";            break;          case -11:            strRet = "该用户被禁用";            break;          case -14:            strRet = "短信内容出现非法字符";            break;          case -4:            strRet = "手机号格式不正确";            break;          case -41:            strRet = "手机号码为空";            break;          case -42:            strRet = "短信内容为空";            break;          case -51:            strRet = "短信签名格式不正确,接口签名格式为：【签名内容】";            break;          case -6:            strRet = "IP限制";            break;          default:            strRet = "发送短信数量：" + result;            break;        }      }      catch (Exception ex)      {        strRet = ex.Message;      }      return strRet;    }  }}

3. 找在线客服开通发送权限，填写好签名，效果图如下：
