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+"×tamp="+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 .URL;
import .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 = "/0822/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);
}
}
–END–
