javaweb项目中实现手机短信登录

javaweb项目中实现手机短信登录
手机号登录在现在的项目中用的场景非常多，实现起来也不难，今天我们就一起来通过演示实现登录过程。

<1>首先需要注册个第三方的账户，比如秒嘀科技等，然后拿到三个参数值：QUERAY_PATH ACCOUNT_SID AUTH_TOKEN
<2>编写获取验证码类getMessage.java

private static final String QUERAY_PATH="xxxx";

private static final String ACCOUNT_SID="xxx";
private static final String AUTH_TOKEN="xxx";
/**
 * @Title: getCode 
 * @Description: TODO( 发送验证码 ) 
 * @param @param phone
 * @param @return    设定文件 
 * @return String    返回类型 
 * @throws
 */
public static String getCode(String phone){
    String ran = smsCode();
    String timestamp = getStamp();
    String sig  = getMD5(ACCOUNT_SID, AUTH_TOKEN, timestamp); 
    String tamp = "您的验证码为"+ran+"，请于{2}分钟内正确输入，如非本人操作，请忽略此短信。";  
    OutputStreamWriter out = null;
    BufferedReader br = null;
    StringBuilder sb = new StringBuilder();
    try {
        URL url = new URL(QUERAY_PATH);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("POST");
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setConnectTimeout(5000);
        connection.setReadTimeout(10000);
        connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
        out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        String args = getArgs(ACCOUNT_SID, tamp, phone, timestamp, sig, "JSON");
         out.write(args);
         out.flush();
         
         br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
        String temp="";
        while ((temp=br.readLine())!=null) {
            sb.append(temp);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    
    JSONObject json = new JSONObject(sb.toString());
    String code = json.getString("respCode");
    String defaultrespcode = "00000"; 
    if(defaultrespcode.equals(code)){
        return ran;
    }else{
        return code;
    }
    
}
/**
 * @Title: getArgs 
 * @Description: TODO( 参数拼接 ) 
 * @param @param accountSid
 * @param @param smsContent
 * @param @param to
 * @param @param timestamp
 * @param @param sig
 * @param @param respDataType
 * @param @return    设定文件 
 * @return String    返回类型 
 * @throws
 */
public static String getArgs(String accountSid,String smsContent,String to,String timestamp,String sig,String respDataType){
    return "accountSid="+accountSid+"&smsContent="+smsContent+"&to="+to+"&timestamp="+timestamp+"&sig="+sig+"&respDataType="+respDataType;    
}

/**
 * @Title: getStamp 
 * @Description: TODO( 获取时间戳 ) 
 * @param @return    设定文件 
 * @return String    返回类型 
 * @throws
 */
public static String getStamp(){
    return    new SimpleDateFormat("yyyyMMddHHmmss").format(new Date());
}
/**
 * @Title: getMD5 
 * @Description: TODO(sig签名 ) 
 * @param @param sid
 * @param @param token
 * @param @param timestamp
 * @param @return    设定文件 
 * @return String    返回类型 
 * @throws
 */
public static String getMD5(String sid,String token,String timestamp){
    StringBuilder sBuilder = new StringBuilder();
    String source = sid + token + timestamp; 
    try {
        MessageDigest instance = MessageDigest.getInstance("MD5");
        byte[] digest = instance.digest(source.getBytes());
        for (byte b : digest) {
            String hexString = Integer.toHexString(b&0xff);
            if(hexString.length()==1){
                sBuilder.append("0"+hexString);
            }else{
                sBuilder.append(hexString);
            }
        }
    } catch (NoSuchAlgorithmException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return sBuilder.toString();
}
/**
 * @Title: smsCode 
 * @Description: TODO( 产生验证码) 
 * @param @return    设定文件 
 * @return String    返回类型 
 * @throws
 */
public static String smsCode(){
    String random = new Random().nextInt(1000000)+"";
    if(random.length()!=6){
        return smsCode();
    }else{
        return random;
    }
}

<3> 编写servlet

protected void doPost(HttpServletRequest req, HttpServletResponse resp)

        throws ServletException, IOException {
    resp.setCharacterEncoding("utf-8");
    String phone = req.getParameter("phone");   
    String code = GetMessage.getCode(phone);
    //手机号登录后
    HttpSession session = req.getSession();
    PrintWriter out = resp.getWriter();
    //检查手机号是否注册过
    checkPhoneDao checkPhoneDao = new checkPhoneImpl();
    boolean results = checkPhoneDao.checkPhone(phone);
    if(!results){
        out.print(code);
        session.setAttribute("name", "phone");
    }else {
        out.print("此手机号没有被注册");
    }
    out.close();
}

<4> dao 层实现 的方法

@Override

public boolean checkPhone(String phone) {
    String sql = "select username from user where phone=?";
    List<Map<String, Object>> queryForList = DbUtil.queryForList(sql, phone);
    if(queryForList.isEmpty()){
        return true;
    }
    return false;
}

到此，短信登录的功能已经实现了，大家可以按照我的思路尝试去实现。注：由于有的小伙伴没有框架基础，所以演示使用jsp+servlet+jdbc实现的。
