标签: android otp

我正在开发一个Android应用程序,其中服务器发送OTP并且用户需要在应用程序中输入此OTP,以登录我的应用程序。我想要的是,我的应用程序应该能够自动读取服务器发送的OTP。我怎样才能做到这一点?在这方面的任何帮助或指导将受到高度赞赏。

我建议您不要使用任何第三方库从SMS收件箱中自动提取OTP。 如果您对广播接收器及其工作原理有基本的了解,则可以轻松完成此操作。 只需尝试以下方法:

  

步骤1)创建单一界面,即SmsListner

package com.wnrcorp.reba;
public interface SmsListener{
public void messageReceived(String messageText);}
  

步骤2)创建单个广播接收器,即SmsReceiver

package com.wnrcorp.reba;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
public class SmsReceiver extends BroadcastReceiver {
private static SmsListener mListener;
Boolean b;
String abcd,xyz;
@Override
public void onReceive(Context context, Intent intent) {
Bundle data  = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
    for(int i=0;i<pdus.length;i++){
        SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
        String sender = smsMessage.getDisplayOriginatingAddress();
       // b=sender.endsWith("WNRCRP");  //Just to fetch otp sent from WNRCRP
        String messageBody = smsMessage.getMessageBody();
       abcd=messageBody.replaceAll("[^0-9]","");   // here abcd contains otp 
        which is in number format
        //Pass on the text to our listener.
        if(b==true) {
            mListener.messageReceived(abcd);  // attach value to interface 
  object
        }
        else
        {
        }
    }
}
public static void bindListener(SmsListener listener) {
    mListener = listener;
}
}
  

步骤3)在Android清单文件中添加监听器,即广播接收器

<receiver android:name=".SmsReceiver">    
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
</receiver>

并添加权限

<uses-permission android:name="android.permission.RECEIVE_SMS"/>

  

最终步骤4)在收件箱中收到otp时自动获取otp的活动。在我的情况下,我正在获取otp并设置edittext字段。

public class OtpVerificationActivity extends AppCompatActivity {
EditText ed;
TextView tv;
String otp_generated,contactNo,id1;
GlobalData gd = new GlobalData();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_otp_verification);
    ed=(EditText)findViewById(R.id.otp);
    tv=(TextView) findViewById(R.id.verify_otp); 
    /*This is important because this will be called every time you receive 
     any sms */            
 SmsReceiver.bindListener(new SmsListener() {
        @Override
        public void messageReceived(String messageText) {
            ed.setText(messageText);     
        }
    });
    tv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try
            {
                InputMethodManager imm=
  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);                    
  imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),0);
            }
            catch(Exception e)
            {}           
            if (ed.getText().toString().equals(otp_generated))
            {
                Toast.makeText(OtpVerificationActivity.this, "OTP Verified 
       Successfully !", Toast.LENGTH_SHORT).show();           
             }
    });
   }
}

答案 1 :(得分:22)

您可以尝试使用简单的库like

通过gradle安装并添加权限后,在onCreate activity等方法中启动SmsVerifyCatcher:

    smsVerifyCatcher = new SmsVerifyCatcher(this, new OnSmsCatchListener<String>() {
    @Override
    public void onSmsCatch(String message) {
        String code = parseCode(message);//Parse verification code
        etCode.setText(code);//set code in edit text
        //then you can send verification code to server
    }
});

此外,覆盖活动生命周期方法:

  @Override
protected void onStart() {
    super.onStart();
    smsVerifyCatcher.onStart();
}

@Override
protected void onStop() {
    super.onStop();
    smsVerifyCatcher.onStop();
}

/**
 * need for Android 6 real time permissions
 */
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    smsVerifyCatcher.onRequestPermissionsResult(requestCode, permissions, grantResults);
}


public String parseCode(String message) {
    Pattern p = Pattern.compile("\\b\\d{4}\\b");
    Matcher m = p.matcher(message);
    String code = "";
    while (m.find()) {
        code = m.group(0);
    }
    return code;
}

我实现了这样的东西。但是,这是我在消息传入时所做的,我只检索六位数代码,将其捆绑在一个意图中并将其发送到需要它的活动或片段并验证代码。该示例向您展示了获取短信的方法。请查看下面的代码,了解如何使用 LocalBrodcastManager 进行发送,如果您的消息包含更多文本,请参阅E.g问候语,将其标准化以帮助您提高效率。例如,您的验证码为:84HG73&#34;您可以创建一个正则表达式模式,如([0-9]){2}([A-Z]){2}([0-9]){2},这意味着两个整数,两个[大写]字母和两个整数。祝你好运!

从邮件中删除所有不需要的信息后

 Intent intent = new Intent("AddedItem");
 intent.putExtra("items", code);
 LocalBroadcastManager.getInstance(getActivity()).sendBroadcast(intent); 

接收片段/活动

@Override
public void onResume() {
    LocalBroadcastManager.getInstance(getActivity()).registerReceiver(receiver, new IntentFilter("AddedItem"));
    super.onResume();
}

@Override
public void onPause() {
    super.onDestroy();
    LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(receiver);
}

代码意味着处理您收集的有效负载

 private BroadcastReceiver receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction()) {
            final String message = intent.getStringExtra("message");
            //Do whatever you want with the code here
        }
    }
};

这有点帮助吗?我使用回调

做得更好

很抱歉迟到的回复,但如果有帮助的话,仍然感觉就像发布我的答案。它适用于6位OTP。

    @Override
    public void onOTPReceived(String messageBody)
    {
        Pattern pattern = Pattern.compile(SMSReceiver.OTP_REGEX);
        Matcher matcher = pattern.matcher(messageBody);
        String otp = HkpConstants.EMPTY;
        while (matcher.find())
        {
            otp = matcher.group();
        }
        checkAndSetOTP(otp);
    }
Adding constants here

public static final String OTP_REGEX = "[0-9]{1,6}";

对于短信听众,可以按照以下课程

public class SMSReceiver extends BroadcastReceiver
{
    public static final String SMS_BUNDLE = "pdus";
    public static final String OTP_REGEX = "[0-9]{1,6}";
    private static final String FORMAT = "format";

    private OnOTPSMSReceivedListener otpSMSListener;

    public SMSReceiver(OnOTPSMSReceivedListener listener)
    {
        otpSMSListener = listener;
    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle intentExtras = intent.getExtras();
        if (intentExtras != null)
        {
            Object[] sms_bundle = (Object[]) intentExtras.get(SMS_BUNDLE);
            String format = intent.getStringExtra(FORMAT);
            if (sms_bundle != null)
            {
                otpSMSListener.onOTPSMSReceived(format, sms_bundle);
            }
            else {
                // do nothing
            }
        }
    }

    @FunctionalInterface
    public interface OnOTPSMSReceivedListener
    {
        void onOTPSMSReceived(@Nullable String format, Object... smsBundle);
    }
}

    @Override
    public void onOTPSMSReceived(@Nullable String format, Object... smsBundle)
    {
        for (Object aSmsBundle : smsBundle)
        {
            SmsMessage smsMessage = getIncomingMessage(format, aSmsBundle);
            String sender = smsMessage.getDisplayOriginatingAddress();
            if (sender.toLowerCase().contains(ONEMG))
            {
                getIncomingMessage(smsMessage.getMessageBody());
            } else
            {
                // do nothing
            }
        }
    }

    private SmsMessage getIncomingMessage(@Nullable String format, Object aObject)
    {
        SmsMessage currentSMS;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && format != null)
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);
        } else
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject);
        }

        return currentSMS;
    }

使用SMS检索器API,无需声明android.permission.READ_SMS即可读取OTP。

  
      
  1. 启动短信检索器
  2.   
    private fun startSMSRetriever() {
        // Get an instance of SmsRetrieverClient, used to start listening for a matching SMS message.
        val client = SmsRetriever.getClient(this /* context */);

        // Starts SmsRetriever, which waits for ONE matching SMS message until timeout
        // (5 minutes). The matching SMS message will be sent via a Broadcast Intent with
        // action SmsRetriever#SMS_RETRIEVED_ACTION.
        val task: Task<Void> = client.startSmsRetriever();

        // Listen for success/failure of the start Task. If in a background thread, this
        // can be made blocking using Tasks.await(task, [timeout]);
        task.addOnSuccessListener {
            Log.d("SmsRetriever", "SmsRetriever Start Success")
        }

        task.addOnFailureListener {
            Log.d("SmsRetriever", "SmsRetriever Start Failed")
        }
    }
  
      
  1. 通过广播接收消息
  2.   
    public class MySMSBroadcastReceiver : BroadcastReceiver() {

        override fun onReceive(context: Context?, intent: Intent?) {
            if (SmsRetriever.SMS_RETRIEVED_ACTION == intent?.action && intent.extras!=null) {
                val extras = intent.extras
                val status = extras.get(SmsRetriever.EXTRA_STATUS) as Status

                when (status.statusCode) {
                    CommonStatusCodes.SUCCESS -> {
                        // Get SMS message contents
                        val message = extras.get(SmsRetriever.EXTRA_SMS_MESSAGE) as String
                        Log.e("Message", message);
                        // Extract one-time code from the message and complete verification
                        // by sending the code back to your server.
                    }
                    CommonStatusCodes.TIMEOUT -> {
                        // Waiting for SMS timed out (5 minutes)
                        // Handle the error ...
                    }
                }
            }
        }

    }   


    /**Don't forgot to define BroadcastReceiver in AndroidManifest.xml.*/

        </intent-filter>
    </receiver>
  
      
  1. 将验证码中的一次性代码发送到您的服务器
  2.   

确保您的SMS格式完全如下:

<#> Your ExampleApp code is: 123ABC78
fBzOyyp9h6L
  1. 不超过140个字节
  2. 以前缀<#>
  3. 开头
  4. 以11个字符的哈希字符串结尾,用于标识您的应用

    您可以使用以下代码计算应用哈希:

由于Google限制了对READ_SMS权限的使用,因此这是没有READ_SMS权限的解决方案。

SMS Retriever API

基本功能是避免使用Android关键权限READ_SMS并使用此方法完成任务。打击是您需要的步骤。

将“发送OTP”发送到用户号码,检查SMS Retriever API是否能够接收消息

SmsRetrieverClient client = SmsRetriever.getClient(SignupSetResetPasswordActivity.this);
Task<Void> task = client.startSmsRetriever();
task.addOnSuccessListener(new OnSuccessListener<Void>() {
    @Override
    public void onSuccess(Void aVoid) {
        // Android will provide message once receive. Start your broadcast receiver.
        IntentFilter filter = new IntentFilter();
        filter.addAction(SmsRetriever.SMS_RETRIEVED_ACTION);
        registerReceiver(new SmsReceiver(), filter);
    }
});
task.addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        // Failed to start retriever, inspect Exception for more details
    }
});

        if (SmsRetriever.SMS_RETRIEVED_ACTION.equals(intent.getAction())) {
            Bundle extras = intent.getExtras();
            Status status = (Status) extras.get(SmsRetriever.EXTRA_STATUS);

            switch (status.getStatusCode()) {
                case CommonStatusCodes.SUCCESS:
                    // Get SMS message contents
                    String otp;
                    String msgs = (String) extras.get(SmsRetriever.EXTRA_SMS_MESSAGE);

                    // Extract one-time code from the message and complete verification
                    break;
                case CommonStatusCodes.TIMEOUT:
                    // Waiting for SMS timed out (5 minutes)
                    // Handle the error ...
                    break;
            }
        }
    }
}

最终步骤。将此接收器注册到您的清单

<receiver android:name=".service.SmsReceiver" android:exported="true">
    <intent-filter>
        <action android:name="com.google.android.gms.auth.api.phone.SMS_RETRIEVED"/>
    </intent-filter>
</receiver>

您的SMS必须如下。

<#> Your OTP code is: 6789
QWsa8754qw2 

这里QWsa8754qw2是您自己的应用程序11个字符的哈希码。遵循此link

  • 不超过140个字节
  • 以前缀<#>
  • 开头
  • 以11个字符的哈希字符串结尾,用于标识您的应用

要导入com.google.android.gms.auth.api.phone.SmsRetriever,请不要忘记将此行添加到您的应用程序build.gradle:

implementation "com.google.android.gms:play-services-auth-api-phone:16.0.0"

是的,这现在也可以在浏览器中实现。 Chrome 在 84 及更高版本中发布了此功能。借助WEBOTP API,我们可以检测移动设备网络上的OTP。

这是一个与 Angular PWA 应用程序集成的 Web-OTP 代码:stackblitz

我知道为时已晚,但为了对其他人保持简单,这是我之前编写的解决方案。 使用此库 Link。您将不必搞砸任何事情。 添加依赖后只需使用此方法。

OtpFetcher.getInstance().verifyOtpByMatchingString(this, "OTP", 21000, object : OtpListener {
            override fun onReceived(messageItem: MessageItem) {
                Toast.makeText(this@MainActivity, "" + messageItem, Toast.LENGTH_SHORT).show()
            }

            override fun onTimeOut() {
                Toast.makeText(this@MainActivity, "TimeOut", Toast.LENGTH_SHORT).show()

            }
        })

您必须传递上下文,例如您的消息的搜索字符串

<块引用>

您在您的消息中期待 OTP 通过“OTP”和超时您想收听 OTP 的时间,仅此而已。您将在 OnRecieved CallBack 中收到简单格式的消息。
