如何从android服务器发送的OTP消息中获取唯一的OTP号码？

Question

我有一个忘记密码页面。我想当 otp 消息到来时它读取 otp 号码和 verify.But 在我的情况下读取 OTP 消息但我只想要 OTP 号码。例如我的 OTP 消息是：- 9563 是您的应用程序重置密码的 OTP。将此视为机密。我在 class.but 的帮助下阅读了这条消息，我只想获得像 (9563) 这样的 OTP 号码。而不是整个 message.Can 有人告诉我我该怎么做吗？？

这是我用来阅读 otp 消息的 class。

    public class IncominMsg extends BroadcastReceiver {

    final SmsManager smsManager = SmsManager.getDefault();
    Context mContext;
    Object[] pdusObj;
    String message;


    @Override
    public void onReceive(Context context, Intent intent) {


        final Bundle bundle = intent.getExtras();


        try {
            if (bundle != null) {
                pdusObj = (Object[]) bundle.get("pdus");
                SmsMessage[] smsMessages = new SmsMessage[pdusObj.length];

                for (int i = 0; i < pdusObj.length; i++) {
                    smsMessages[i] = SmsMessage.createFromPdu((byte[]) pdusObj[i]);

                    message = smsMessages[i].getDisplayMessageBody();
                    Log.e("message..", message);
                }


                Pattern generalOtpPattern = Pattern.compile(message);
                Matcher generalOtpMatcher = generalOtpPattern.matcher(smsMessages[0].getMessageBody().toString());

                if (generalOtpMatcher.find()) {
                    String otp = generalOtpMatcher.group(1);//this is only your OTP code


                }


            }


        } catch (Exception e) {

        }
    }


}

我收到消息并打印在 logcat.but 我只想要 OTP 号码而不是整个消息。

试试这个可能对你有帮助

public static String GENERAL_OTP_TEMPLATE = "Your verification code: (.*).";

SmsMessage[] message = new SmsMessage[objectArray.length];
for (int i = 0; i < objectArray.length; i++) {
 message[i] = SmsMessage.createFromPdu((byte[]) objectArray[i]);

}
Pattern generalOtpPattern = Pattern.compile(GENERAL_OTP_TEMPLATE);
Matcher generalOtpMatcher = generalOtpPattern.matcher(message[0].getMessageBody().toString());

if (generalOtpMatcher.find()) {
   String otp = generalOtpMatcher.group(1);//this is only your OTP code

}

make GENERAL_OTP_TEMPLATE is as per you message content and than after check it.
