使用java在项目完成手机短信登录

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。 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 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; } }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(); }dao 层实现 的方法 @Override public boolean checkPhone(String phone) { String sql = "select username from user where phone=?"; List 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。有不懂的可以联系QQ:2217087909 。 当然也可以用阿里云上的短信服务：https://help.aliyun.com/document_detail/387379.html?spm=5176.basicInfo-index.help.dexternal.530f4bab3taNLL 这个是文档，写的比较详细，按照文档基本都能搞定哦！ 附上云服务器：阿里云服务器ECS新春特惠 服务器领券地址 |
