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";/** * @ : getCode  * @De ion: 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();    }        JSON  json = new JSON (sb.toString());    String code = json.getString("respCode");    String defaultrespcode = "00000";     if(defaultrespcode.equals(code)){        return ran;    }else{        return code;    }    }/** * @ : getArgs  * @De ion: 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;    }/** * @ : getStamp  * @De ion: 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());}/** * @ : getMD5  * @De ion: 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();}/** * @ : smsCode  * @De ion: 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,  >> 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。
