javaweb项目如何实现手机短信登录

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。

一、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

二、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;

}

}

三、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();

}

四、 dao 层实现 的方法

@Override

public boolean checkPhone(String phone) {

String sql = "select username from user where phone=?";

List

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。
