第一次发博，发个简单的Java程序发送手机短信验证

最近在准备一个项目，想的登录时候用手机验证，就通过上网查阅了一下手机验证的实现方法，原来超级简单，下面将一步一步介绍。

1.去中国网建注册一个账号密码，首次注册送五条免费短信和3条免费彩信。具体的网址是

http://www.smschinese.cn/api.shtml

2.注册完成之后进去查看给你的短信秘钥

3.有了这个秘钥就超级简单了，导入jar包，下面的代码第一个基本不用该，直接粘贴，第二个改成自己的信息就可以了

这就是测试代码，里面的内容改成你自己的。

 package duanxinyanzheng;

 import java.util.HashMap;
 import java.util.Map;

 /**
  * @Title: http://www.smschinese.cn/api.shtml
  * @date 2011-3-22
  * @version V1.2
  */
 public class test {

     //用户名
     private static String Uid = "你自己的";

     //接口安全秘钥
     private static String Key = "你的秘钥(不是登录密码)";

     //手机号码，多个号码如13800000000,13800000001,13800000002
     private static String smsMob = "18434391711";

     //短信内容
     private static String smsText = "这是自己的测试!【这是验证格式的必须填】";

     public static void main(String[] args) {

         HttpClientUtil client = HttpClientUtil.getInstance();

         //UTF发送
         int result = client.sendMsgUtf8(Uid, Key, smsText, smsMob);
         if(result>0){
             System.out.println("UTF8成功发送条数=="+result);
         }else{
             System.out.println(client.getErrorMsg(result));
         }
     }
 }

上述就可以运行了，是不是超级简单，以前觉得好深奥。上面需要注意 秘钥不是登录密码，内容后面要加上【公司名称】，便于接口进行校验。
