手機號登錄在現在的項目中用的場景非常多,實現起來也不難,今天我們就一起來通過演示實現登錄過程。
一、首先需要注冊個第三方的賬戶,比如秒嘀科技等,然后拿到三個參數值:QUERAY_PATH ACCOUNT_SID AUTH_TOKEN
二、編寫獲取驗證碼類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( 發送驗證碼 ) * @param @param phone * @param @return 設定文件 * @return String 返回類型 * @throws */ public static String getCode(String phone){ String ran = smsCode(); String timestamp = getStamp(); String sig = getMD5(ACCOUNT_SID, AUTH_TOKEN, timestamp); String tamp = "您的驗證碼為"+ran+",請于{2}分鐘內正確輸入,如非本人操作,請忽略此短信。"; 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( 參數拼接 ) * @param @param accountSid * @param @param smsContent * @param @param to * @param @param timestamp * @param @param sig * @param @param respDataType * @param @return 設定文件 * @return String 返回類型 * @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( 獲取時間戳 ) * @param @return 設定文件 * @return String 返回類型 * @throws */ public static String getStamp(){ return new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()); } /** * @Title: getMD5 * @Description: TODO(sig簽名 ) * @param @param sid * @param @param token * @param @param timestamp * @param @return 設定文件 * @return String 返回類型 * @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( 產生驗證碼) * @param @return 設定文件 * @return String 返回類型 * @throws */ public static String smsCode(){ String random = new Random().nextInt(1000000)+""; if(random.length()!=6){ return smsCode(); }else{ return random; } }
三、編寫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); //手機號登錄后 HttpSession session = req.getSession(); PrintWriter out = resp.getWriter(); //檢查手機號是否注冊過 checkPhoneDao checkPhoneDao = new checkPhoneImpl(); boolean results = checkPhoneDao.checkPhone(phone); if(!results){ out.print(code); session.setAttribute("name", "phone"); }else { out.print("此手機號沒有被注冊"); } out.close(); }
四、 dao 層實現 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,短信登錄的功能已經實現了,大家可以按照我的思路嘗試去實現。注:由于有的小伙伴沒有框架基礎,所以演示使用jsp+servlet+jdbc實現的。
