C#怎么实现手机短信发送功能

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:
