短信验证

在我们开发一套新的系统中，现在短信验证是非常常见的，比如修改密码，发送验证码等等，今天就对于简单的短信验证进行一个说明

首先了解一下短信验证的一个原理：我们通过图示的方式进行了解

 由上面的图示可以看出，在短信发送过程中并不是直接发送给用户的，而是通过短信运营商来进行实现的，

现在短信运营商有很多：今天我们以中国网建为例

下面是对中国网建进行的一系列操作：

使用中国网建作为短信运营商的的操作流程

1.进行注册

2.通过用户名和密码进行登录

3.设置签名（尽量不要设置大型公司的名称）

4.编辑短信内容

5.设置要发送给那个手机号码

6.整合到代码中点击短信API接口

7.进行示例程序的下载（里面会包括三个jar包）

8.对里面包含的.txt文件进行查看，了解其里面所定义的变量的含义

9.修改短信安全秘钥（在中国网建登录成功会左侧边栏就可以看到）

前面1-6步骤直接搜索中国网建就可以进行相关的操作

后面7-9步骤实在代码中需要修改的地方，详细了解请查看下面的代码

第三步：进行一个实践

首先将步骤7下载下来的示例程序解压，并将自己需要的导入进自己使用的开发工具中，在这以eclipse为例

导入后的的效果：

 下面是详细代码：

import java.util.Map;

/**

* @date 2011-3-22
* @version V1.2 
*/
public class test {

//用户名，是注册是自己所填的用户名
private static String Uid = "来自地狱的勇士";

//接口安全秘钥，当你注册成功并登陆后，会有以下修改短信秘钥的选项，点击进去进行赋值
private static String Key = "d41d8cd98f00b204e980";

//手机号码，多个号码如13800000000,13800000001,13800000002，这个电话号码填的是你要发送短信的用户的电话号码
private static String smsMob = "***************";

//短信内容
private static String smsText = "验证码：8888";


public static void main(String[] args) {

HttpClientUtil client = HttpClientUtil.getInstance();
//随机生成一个验证码
int num=(int)(Math.random()*10000);
smsText=num+"";
//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));
}
}
}

以上就是对于整个短信发送验证的全部内容
