javaweb專案中實現手機簡訊登入
阿新 • • 發佈:2019-01-05
手機號登入在現在的專案中用的場景非常多,實現起來也不難,今天我們就一起來通過演示實現登入過程。
<1>首先需要註冊個第三方的賬戶,比如秒嘀科技等,然後拿到三個引數值:QUERAY_PATH ACCOUNT_SID AUTH_TOKEN
<2>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( 傳送驗證碼 )
* @param @param phone
* @param @return 設定檔案
* @return String 返回型別
* @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+",請於{2}分鐘內正確輸入,如非本人操作,請忽略此簡訊。";
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( 引數拼接 )
* @param @param accountSid
* @param @param smsContent
* @param @param to
* @param @param timestamp
* @param @param sig
* @param @param respDataType
* @param @return 設定檔案
* @return String 返回型別
* @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 設定檔案
* @return String 返回型別
* @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 設定檔案
* @return String 返回型別
* @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 設定檔案
* @return String 返回型別
* @throws
*/
public static String smsCode(){
String random = new Random().nextInt(1000000)+"";
if(random.length()!=6){
return smsCode();
}else{
return random;
}
}
<3> 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);
//手機號登入後
HttpSession session = req.getSession();
PrintWriter out = resp.getWriter();
//檢查手機號是否註冊過
checkPhoneDao checkPhoneDao = new checkPhoneImpl();
boolean results = checkPhoneDao.checkPhone(phone);
if(!results){
out.print(code);
session.setAttribute("name", "phone");
}else {
out.print("此手機號沒有被註冊");
}
out.close();
}
<4> 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,簡訊登入的功能已經實現了,大家可以按照我的思路嘗試去實現。注:由於有的小夥伴沒有框架基礎,所以演示使用jsp+servlet+jdbc實現的。有不懂的可以聯絡QQ:2217087909。
