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+"×tamp="+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<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。

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
