谷歌Play服务有两个api，可用于简化基于短信的验证过程

短信检索器接口

提供完全自动化的用户体验，不需要用户手动输入验证码，也不需要任何额外的应用权限，应该在可能的情况下使用。但是，它要求您在消息体中放置自定义哈希代码，因此您还必须控制服务器端。

消息要求-唯一标识应用程序的11位哈希码 发件人要求—无 用户交互—无

在Android应用程序中请求短信验证

在服务器上进行短信验证

短信用户同意API

不需要自定义哈希码，但需要用户批准你的应用程序的请求，以访问包含验证码的消息。为了最大限度地减少向用户显示错误消息的机会，SMS用户同意将从用户的联系人列表中过滤出发件人的消息。

消息要求-至少包含一个数字的4-10位字母数字代码 发件人要求-发件人不能在用户的联系人列表中 用户交互-一键批准

短信用户同意API是谷歌播放服务的一部分。要使用它，你至少需要这些库的17.0.0版本:

implementation "com.google.android.gms:play-services-auth:17.0.0"
implementation "com.google.android.gms:play-services-auth-api-phone:17.1.0"

第一步:开始监听短信

SMS用户同意将监听包含一次性代码的传入SMS消息长达五分钟。它不会查看在启动之前发送的任何消息。如果知道发送一次性代码的电话号码，则可以指定senderPhoneNumber，如果不指定，则null将匹配任何号码。

 smsRetriever.startSmsUserConsent(senderPhoneNumber /* or null */)

步骤2:请求同意阅读消息

一旦你的应用程序接收到包含一次性代码的消息，它就会被广播通知。在这一点上，你没有同意阅读消息-相反，你给了一个意图，你可以开始提示用户同意。在你的BroadcastReceiver内部，你使用extras中的Intent来显示提示。 当您启动该意图时，它将提示用户允许读取单个消息。他们将会看到与你的应用共享的全部文本。

val consentIntent = extras.getParcelable<Intent>(SmsRetriever.EXTRA_CONSENT_INTENT)
startActivityForResult(consentIntent, SMS_CONSENT_REQUEST)

第三步:解析一次性代码，完成短信验证

当用户点击“允许”-是时候真正阅读消息了!在onActivityResult内部，你可以从数据中获得短信的全文:

val message = data.getStringExtra(SmsRetriever.EXTRA_SMS_MESSAGE)

然后解析SMS消息并将一次性代码传递到后端!

String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;

改变了:

String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0 " : SMS_READ_COLUMN + " = 1 ";

用1个Python函数获取所有短信:

我写了一个python函数，从f-droid安装SMS导入/导出，然后使用adb通过USB将手机中的SMS文件导入到pc中。

改进空间

我最初修改了配置，将计划设置为在下一分钟导出，然后等待那一分钟，然而什么都没有发生。因此，我发送手动击键来导出sms消息。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        final String myPackageName = getPackageName();
        if (!Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName)) {

            intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, myPackageName);
            startActivityForResult(intent, 1);
        }else {
            List<Sms> lst = getAllSms();
        }
    }else {
        List<Sms> lst = getAllSms();
    }

将app设置为默认短信app

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
    if (resultCode == RESULT_OK) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

                    .getColumnIndexOrThrow("address")));
            objSms.setMsg(c.getString(c.getColumnIndexOrThrow("body")));
            objSms.setReadState(c.getString(c.getColumnIndex("read")));
            objSms.setTime(c.getString(c.getColumnIndexOrThrow("date")));
            if (c.getString(c.getColumnIndexOrThrow("type")).contains("1")) {
                objSms.setFolderName("inbox");
            } else {
                objSms.setFolderName("sent");
            }

            lstSms.add(objSms);
            c.moveToNext();
        }
    }
    // else {
    // throw new RuntimeException("You have no SMS");
    // }
    c.close();

    return lstSms;
}

短信类如下:

public class Sms{
private String _id;
private String _address;
private String _msg;
private String _readState; //"0" for have not read sms and "1" for have read sms
private String _time;
private String _folderName;

public String getId(){
return _id;
}
public String getAddress(){
return _address;
}
public String getMsg(){
return _msg;
}
public String getReadState(){
return _readState;
}
public String getTime(){
return _time;
}
public String getFolderName(){
return _folderName;
}


public void setId(String id){
_id = id;
}
public void setAddress(String address){
_address = address;
}
public void setMsg(String msg){
_msg = msg;
}
public void setReadState(String readState){
_readState = readState;
}
public void setTime(String time){
_time = time;
}
public void setFolderName(String folderName){
_folderName = folderName;
}

}

不要忘记在AndroidManifest.xml中定义权限

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

谷歌Play服务有两个api，可用于简化基于短信的验证过程

短信检索器接口

提供完全自动化的用户体验，不需要用户手动输入验证码，也不需要任何额外的应用权限，应该在可能的情况下使用。但是，它要求您在消息体中放置自定义哈希代码，因此您还必须控制服务器端。

消息要求-唯一标识应用程序的11位哈希码 发件人要求—无 用户交互—无

在Android应用程序中请求短信验证

在服务器上进行短信验证

短信用户同意API

不需要自定义哈希码，但需要用户批准你的应用程序的请求，以访问包含验证码的消息。为了最大限度地减少向用户显示错误消息的机会，SMS用户同意将从用户的联系人列表中过滤出发件人的消息。

消息要求-至少包含一个数字的4-10位字母数字代码 发件人要求-发件人不能在用户的联系人列表中 用户交互-一键批准

短信用户同意API是谷歌播放服务的一部分。要使用它，你至少需要这些库的17.0.0版本:

implementation "com.google.android.gms:play-services-auth:17.0.0"
implementation "com.google.android.gms:play-services-auth-api-phone:17.1.0"

第一步:开始监听短信

SMS用户同意将监听包含一次性代码的传入SMS消息长达五分钟。它不会查看在启动之前发送的任何消息。如果知道发送一次性代码的电话号码，则可以指定senderPhoneNumber，如果不指定，则null将匹配任何号码。

 smsRetriever.startSmsUserConsent(senderPhoneNumber /* or null */)

步骤2:请求同意阅读消息

一旦你的应用程序接收到包含一次性代码的消息，它就会被广播通知。在这一点上，你没有同意阅读消息-相反，你给了一个意图，你可以开始提示用户同意。在你的BroadcastReceiver内部，你使用extras中的Intent来显示提示。 当您启动该意图时，它将提示用户允许读取单个消息。他们将会看到与你的应用共享的全部文本。

val consentIntent = extras.getParcelable<Intent>(SmsRetriever.EXTRA_CONSENT_INTENT)
startActivityForResult(consentIntent, SMS_CONSENT_REQUEST)

第三步:解析一次性代码，完成短信验证

当用户点击“允许”-是时候真正阅读消息了!在onActivityResult内部，你可以从数据中获得短信的全文:

val message = data.getStringExtra(SmsRetriever.EXTRA_SMS_MESSAGE)

然后解析SMS消息并将一次性代码传递到后端!

第一步:首先我们必须在清单文件中添加权限 就像

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

步骤2:添加服务短信接收类，用于接收短信

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

步骤3:添加运行时权限

private boolean checkAndRequestPermissions()
{
    int sms = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS);

    if (sms != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

第四步:在应用程序中添加这些类并进行测试 接口类

public interface SmsListener {
   public void messageReceived(String messageText);
}

SmsReceiver.java

public class SmsReceiver extends BroadcastReceiver {
    private static SmsListener mListener;
    public Pattern p = Pattern.compile("(|^)\\d{6}");
    @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();
            String phoneNumber = smsMessage.getDisplayOriginatingAddress();
            String senderNum = phoneNumber ;
            String messageBody = smsMessage.getMessageBody();
            try{
                if(messageBody!=null){
                    Matcher m = p.matcher(messageBody);
                    if(m.find()) {
                        mListener.messageReceived(m.group(0));
                    }
                }
            }
            catch(Exception e){}
        }
    }
    public static void bindListener(SmsListener listener) {
        mListener = listener; 
    }
}
