我正在开发一个 Android 应用程序，其中服务器发送一个 OTP，用户需要在应用程序中输入这个 OTP，以注册我的应用程序。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不胜感激。

我建议您不要使用任何第三方库从 SMS Inbox 自动获取 OTP。如果您对广播接收器及其工作原理有基本的了解，这可以很容易地完成。只需尝试以下方法：

  1. 创建单个接口，即 SmsListner
package com.wnrcorp.reba;
public interface SmsListener {
    public void messageReceived(String messageText);
}
  1. 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;
    }
}
  1. 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"/>
  1. 当收件箱中收到 otp 时，您将在其中自动获取 otp 的活动。就我而言，我正在获取 otp 并在 edittext 字段上进行设置。
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();           
                            }
                        });
                }
            }
}

OtpVerificationActivity 的布局文件

您可以尝试使用一个简单的库，例如

通过 gradle 安装并添加权限后，在 onCreate 活动等方法中启动 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;
}

由于谷歌限制使用 READ_SMS 权限，这里是没有 READ_SMS 权限的解决方案。

短信检索器 API

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

将发送 OTP 发送到用户的号码，检查 SMS Retriever API 是否能够获取消息

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
    }
});

广播接收器代码

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;

import com.google.android.gms.auth.api.phone.SmsRetriever;
import com.google.android.gms.common.api.CommonStatusCodes;
import com.google.android.gms.common.api.Status;

public class SmsReceiver extends BroadcastReceiver {

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

最后一步。将此接收器注册到您的清单中

<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>

您的短信必须如下。

<#> Your OTP code is: 6789
QWsa8754qw2

这里 QWsa8754qw2 是你自己的应用程序的 11 字符哈希码。按照这个链接

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

要导入com.google.android.gms.auth.api.phone.SmsRetriever，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"

我实现了这样的东西。但是，当消息进来时，这是我所做的，我只检索六位数的代码，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式。查看下面的代码以了解如何使用LocalBrodcastManager进行发送，如果您的消息包含更多文本，例如问候语，请将其标准化以更好地帮助您。例如“您的验证码是：84HG73”，您可以创建一个像这样的正则表达式模式，([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！

从消息中丢弃所有不需要的信息后

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

以及接收它的片段/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);
}

以及用于处理您收集的有效负载的代码

 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
        }
    }
};

是不是有点帮助。我通过使用回调做得更好

抱歉回复晚了，但如果有帮助，我仍然想发布我的答案。它适用于 6 位数的 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 SMS 侦听器，可以遵循以下课程

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

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

  1. 启动短信检索器
    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
    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.*/       
    <receiver android:name=".MySMSBroadcastReceiver" android:exported="true">
        <intent-filter>
            <action android:name="com.google.android.gms.auth.api.phone.SMS_RETRIEVED"/>
        </intent-filter>
    </receiver>
  1. 将验证消息中的一次性代码发送到您的服务器

确保您的短信格式如下：

<#> Your ExampleApp code is: 123ABC78
fBzOyyp9h6L
  1. 不超过 140 字节
  2. 以前缀 <#> 开头

  3. 以标识您的应用的 11 个字符的哈希字符串结尾

    您可以使用以下代码计算应用哈希：

    import android.content.Context
import android.content.ContextWrapper
import android.content.pm.PackageManager
import android.util.Base64
import android.util.Log
import java.nio.charset.StandardCharsets
import java.security.MessageDigest
import java.security.NoSuchAlgorithmException
import java.util.*

/**

        const val NUM_HASHED_BYTES = 9;
        const val NUM_BASE64_CHAR = 11;
    }

    /**
     * Get all the app signatures for the current package
     * @return

            // Get all package signatures for the current package
            val signatures = packageManager.getPackageInfo(
                packageName,
                PackageManager.GET_SIGNATURES
            ).signatures;

            // For each signature create a compatible hash
            for (signature in signatures) {
                val hash = hash(packageName, signature.toCharsString());
                if (hash != null) {
                    appCodes.add(String.format("%s", hash));
                }
            }

            messageDigest.update(appInfo.toByteArray(StandardCharsets.UTF_8));
            var hashSignature = messageDigest.digest();

            // truncated into NUM_HASHED_BYTES
            hashSignature = Arrays.copyOfRange(hashSignature, 0, NUM_HASHED_BYTES);
            // encode into Base64
            var base64Hash = Base64.encodeToString(hashSignature, Base64.NO_PADDING or Base64.NO_WRAP);
            base64Hash = base64Hash.substring(0, NUM_BASE64_CHAR);

            Log.e(TAG, String.format("pkg: %s -- hash: %s", packageName, base64Hash));
            return base64Hash;
        } catch (e: NoSuchAlgorithmException) {
            Log.e(TAG, "hash:NoSuchAlgorithm", e);
        }
        return null;
    }
}

所需的梯度：

我知道已经晚了，但为了让其他人保持简单，这是我之前写的解决方案。使用这个图书馆链接。你不必搞砸任何事情。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()

            }
        })

例如，您必须传递消息的上下文、搜索字符串

您在消息中期待 OTP 传递“OTP”并超时您想听 OTP 多长时间，就是这样。您将在 OnRecieved CallBack 中以简单格式收到您的消息。

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

这是与 Angular PWA 应用程序的 Web-OTP 集成代码：https ://github.com/Rohit3230/webOtpAutoReadByAngular
