   因为移动端的方便，现在网络上很多的网站与应用都有与实现用户手机绑定的功能。这样做的好处很多，例如账号登陆、修改密码、在线支付……等功能模块都可以与手机实时获取验证码短信结合，来确保用户的安全性操作。

   而这整功能模块的实现，我把它大致分为三个步骤：

（1）前端触发获取验证码,同步显示有效验证倒计时；

（2）后台通过代理平台发送验证短信；

（3）用户提交验证信息，后台逻辑判断处理。

一、首先，与大家分享下前端的实现：

如图：输入完正确的手机号码后再触发有效验证倒计时。

js代码如下（头部需引入jQuery）：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 function  getCode(){          var  tel = $( "#mobile" ).val(); //获取手机号码输入框值          var  reg = /^1[3|4|5|8][0-9]\d{4,8}$/;          if (!reg.test(tel)){  //校验手机号码格式              alert( "请先输入您的正确手机号！" );              document.form1.o_tel.focus();              return  false ;          }          var  paras =  "o_tel=" +tel;          //jquery post方法同步提交          //（提交地址；   data：返回值）          $.post( '<%=basePath%>mobile/sendCode?' +paras, function (data) {              if (data!= null && typeof (data)!= "undefined" ){                  var  msg = data.msg;   //返回值为json格式                  if (msg!= null && typeof (msg)!= "undefined" &&msg== "SUCCESS" ){                      get_code_time();   //发送成功则出发get_code_time（）函数                  } else {                      alert( "短信验证码发送失败！请重新获取。" );                  }              } else {                  alert( "短信验证码发送失败！请重新获取。" );              }          }, "json" );      }      var  wait = 120;      function  get_code_time(){          if (wait==0){              $( "#updateverify" ).removeAttr( "disabled" ); //移除获取验证码按钮的disabled属性              $( "#updateverify" ).val( "获取验证码" );              wait = 120;          } else {              $( "#updateverify" ).attr( "disabled" ,  true ); //设置获取验证码按钮为不可触发              $( "#updateverify" ).val( "剩("  + wait +  ")秒" );              wait--;              setTimeout( "get_code_time()" , 1000);          }      }

二、接下来我们就该在后台进行短息发送处理了（Demo是用Java整合spring MVC框架写的）：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 /**       * 订单查询发送验证码       * @param request       * @param response       * @return       */      @RequestMapping (value= "/sendCode" ,method={RequestMethod.POST,RequestMethod.GET})      public  String sendCode(HttpServletRequest request,HttpServletResponse response){                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    HttpSession session = request.getSession();          String ret= "" ;          String o_tel = request.getParameter( "o_tel" ); //获取前端传送过来的电话号码          if (o_tel!= null &&o_tel!= "" ){              int  Random  = ( int ) ((Math.random()* 9 + 1 )* 1000 ); //随机生成的4位数（验证码）              String mes = Random+ "(用于测试的验证码，两分钟内有效)【学而思博客】" ; //需在短信中显示的文字信息描述              ApiSendMobile asm =  new  ApiSendMobile();              String msg = asm.sendSM(o_tel, mes); //发送短信                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            if ( "发送成功" .equals(msg)){                  ret =  "{\"msg\":\"SUCCESS\"}" ;                  //把验证码与电话号码存入session中，并设置120秒有效期限                  session.setAttribute( "code" , Random);                  session.setAttribute( "tel" , o_tel);                  session.setMaxInactiveInterval( 2 * 60 );              } else  {                  ret =  "{\"msg\":\"ERROR\"}" ;              }                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        } else {              ret =  "{\"msg\":\"ERROR\"}" ;          }                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    response.setContentType( "application/json;charset=UTF-8" );          PrintWriter writer =  null ;          try  {              writer = response.getWriter();          }  catch  (IOException e) {              e.printStackTrace();          }          writer.write(ret); //推送回前端                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    return  null ;      }

   后台的大概逻辑就是这样，不熟悉SpringMVC的请不要在意太多细节。因为接下来的才是我要说的关键点：

ApiSendMobile asm = new ApiSendMobile();

   String msg = asm.sendSM(o_tel, mes);

   嗯，没错ApiSendMobile这货是我已经封装好的一个类。先来说说目前我们常用的发送短信方法，

1、与运营商联系，调用运营商的接口，把要发送的内容与手机号给运营商，让运营商去发送。（例如Mas机平台，附上相关链接：http://blog.csdn.net/wufeishimeng/article/details/4204093）

2、自己去买设备，然后在基于它进行二次开发（例如短信猫，相关链接：http://my.oschina.net/backtract/blog/133629）

3、专门的短信服务公司，让后通过网络服务形式调用第三方接口发送（例如飞信）

   额，才疏学浅。目前我知道的就这三种吧，其中第一种方式是稳定快速有保障的（因为运营商们要收费），第二种就出现延迟或者遗漏现象的几率就会很大，最后一种不知道现在是否还可行了。

   我们言归正传，本文的例子就是用了第一种方法，上代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 package  com.xiaoxm.util;

         Thread.currentThread().interrupt();      }                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      public  String  sendSM(String mobile,String sendContent)      {          init();  //初始化 相关参数          String  msg =  "" ;          int  result =  0 ;          result = handler.sendSM(mobile, sendContent, smId );          if (result == APIClient.IMAPI_SUCC)          {                   msg =  "发送成功" ;          }          else  if (result == APIClient.IMAPI_INIT_ERR)              msg =  "未初始化" ;          else  if (result == APIClient.IMAPI_CONN_ERR)              msg =  "数据库连接失败" ;          else  if (result == APIClient.IMAPI_DATA_ERR)              msg =  "参数错误" ;          else  if (result == APIClient.IMAPI_DATA_TOOLONG)              msg =  "消息内容太长" ;          else  if (result == APIClient.IMAPI_INS_ERR)              msg =  "数据库插入错误" ;          else              msg =  "出现其他错误" ;                                                                                                                                                                                                                                                                                                                                                                                                                                                  release();   //释放资源                                                                                                                                                                                                                              return  msg;      }                                                                                                                                                                                                                      public  void  error(Object obj , Throwable thr)      {          info(obj);          thr.printStackTrace();      }      public  void  info(Object obj)      {          System.out.println(obj);      }                                                                                                                                                                                                                      public  void  quit()      {          release();          System.exit( 0 );      } }

   因为涉及到隐私，所以什么地址、用户名密码之类的，自己去向运营商联系获取吧……

   要注意哦：这个类里引入了importcom.jasson.im.api.APIClient;

   还有就是项目中也必须加一个jar包：ImApi.jar

如果有去和运营商合作的话，他们会给你文档和所需的开发包之类的，所以你大可放心。

   嗯，该功能模块的核心内容都已经介绍得差不多了，就只剩下用户查看短信验证信息，输入了传到后台，然后再获取刚才发送短信成功时存入session中连个值进行对比验证。我也就不在此啰嗦……

   结语：天下没有白吃的午餐，垄断行业就是屌。水平不足，文章中也许存在着许多不足之处，还望大家指点与纠正。坚持博客精神，分享是一种快乐！
