在网站开发中的注册模块中，短信接收验证码是大部分网站必不可少的功能。这里我就简单总结了一下实现发送短信验证码的功能。

这里用的是秒滴短信服务平台。新用户注册给200条短信，测试够用了。

下面直接上实现代码吧，我这里主要是用作记录笔记大家也可以参考一下。

创建一个RandUtil类，用于生成验证码：

package org.hellohao.ustil;

import java.util.Random;

public class RandUtil {

public static String getRandNum() {

String randNum = new Random().nextInt(1000000)+"";

System.out.println("生成"+randNum);

if (randNum.length()!=6) { //如果生成的不是6位数随机数则返回该方法继续生成

return getRandNum();

}

return randNum;

}

}

创建QueryUtil类：

package org.hellohao.ustil;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.text.SimpleDateFormat;

import java.util.Date;

public class QueryUtil {

public static String queryArguments(String ACCOUNT_SID,String AUTH_TOKEN, String smsContent,String to) {

String timestamp = getTimestamp(); //时间戳

String sig = MD5(ACCOUNT_SID,AUTH_TOKEN,timestamp);//签名认证

String str = "accountSid="+ACCOUNT_SID+"&smsContent="+

smsContent+"&to="+to+"&timestamp="+timestamp+"&sig="+sig;

return str;

}

/**

* MD5加密

* @param args

* @return

*/

public static String MD5(String... args){ //动态参数

StringBuffer result = new StringBuffer();

if (args == null || args.length == 0) {

return "";

} else {

StringBuffer str = new StringBuffer();

for (String string : args) {

str.append(string);

}

System.out.println("加密前：\t"+str.toString());

try {

MessageDigest digest = MessageDigest.getInstance("MD5");

byte[] bytes = digest.digest(str.toString().getBytes());

for (byte b : bytes) {

String hex = Integer.toHexString(b&0xff); //转化十六进制

if (hex.length() == 1) {

result.append("0"+hex);

}else{

result.append(hex);

}

}

} catch (NoSuchAlgorithmException e) {

e.printStackTrace();

}

}

System.out.println("加密后：\t"+result.toString());

return result.toString();

}

/*

* 获取时间戳

*/

public static String getTimestamp(){

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");

Date date = new Date();

return sdf.format(date);

}

}

创建实现发送短信的类GetMessage：

package org.hellohao.ustil;

import net.sf.json.JSONObject;

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.URL;

import java.net.URLConnection;

public class GetMessage {

static String user="张三";

/**

* 用户ID

*/

public static final String ACCOUNT_SID = "xxxxxx";//这里填写你在平台里的ACOUNT_SID

/**

* 密钥

*/

public static final String AUTH_TOKEN = "xxxxxx";

/**

* 请求地址前半部分

*/

public static final String BASE_URL = "https://api.miaodiyun.com/20150822/industrySMS/sendSMS";//请求地址是固定的不用改

public static String randNum = RandUtil.getRandNum();

public static String smsContent = "【世豪有限公司】亲爱的"+user+"，您的验证码为"+randNum+"，请于"+2+"分钟内正确输入，如非本人操作，请忽略此短信。";

/**

* (获取短信验证码)

* @param to

* @return String

*/

public static String getResult(String to) {

randNum = RandUtil.getRandNum();

String smsContent = "【世豪有限公司】亲爱的"+user+"，您的验证码为"+randNum+"，请于"+2+"分钟内正确输入，如非本人操作，请忽略此短信。"; //这里的randNum 和 smsContent和上面的静态变量是一样的，可删除可保留

String args = QueryUtil.queryArguments(ACCOUNT_SID, AUTH_TOKEN, smsContent, to);

OutputStreamWriter out = null;

InputStream in = null;

BufferedReader br = null;

StringBuffer sb = new StringBuffer();

try {

URL url = new URL(BASE_URL);

URLConnection connection = url.openConnection(); //打开链接

connection.setDoOutput(true);

connection.setDoInput(true);

connection.setConnectTimeout(5000); //设置链接超时

connection.setReadTimeout(10000); //设置读取超时

//提交数据

out = new OutputStreamWriter(connection.getOutputStream(),"utf-8");

out.write(args);

out.flush();

//读取返回数据

br = new BufferedReader(new InputStreamReader(connection.getInputStream()));

String line = "";

while((line = br.readLine())!=null){

sb.append(line);

}

} catch (Exception e) {

e.printStackTrace();

}finally {

try {

if (br!=null) {

br.close();

}

if (out!=null) {

out.close();

}

} catch (Exception e2) {

e2.printStackTrace();

}

}

JSONObject jsonObject = JSONObject.fromObject(sb.toString());

System.out.println(jsonObject);

Object object = jsonObject.get("respCode");

System.out.println("状态码："+object+"验证码："+randNum);

System.out.println(!object.equals("00000"));

if (!object.equals("00000")) {

return object.toString();

}else{

return randNum;

}

}

// 测试功能

public static void main(String[] args) {

String result = getResult("15555555555"); //这里填写要接受验证码的手机号

System.out.println("验证码："+randNum+"\t"+result);

}

}
