未经READ_SMS权限的android短信验证 [英] android sms verification without READ_SMS permission

问题描述

我知道，使用Android O，我们现在可以读取SMS验证，而无需READ_SMS权限.可以使用createAppSpecificSmsToken API来完成.

但是我需要一个完整的示例来演示整个SMS验证例程.

I know that with Android O, now we can read SMS verification without requiring READ_SMS permission. It could be done using createAppSpecificSmsToken API.

But I need a complete example to demonstrate whole of SMS verification routine.

推荐答案

没有太多内容.调用SmsManager上的createAppSpecificSmsToken()，提供PendingIntent.您会得到String返回，这是令牌.如果设备收到带有该令牌的SMS，则您的PendingIntent运行，并触发您指定的任何组件.

There is not much to it. Call createAppSpecificSmsToken() on SmsManager, supplying a PendingIntent. You get a String back which is the token. If the device receives an SMS with that token, your PendingIntent is run, triggering whatever component you specified.

package com.commonsware.android.sms.token;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.widget.TextView;

public class MainActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SmsManager mgr=SmsManager.getDefault();
    String token=mgr.createAppSpecificSmsToken(buildPendingIntent());
    TextView tv=(TextView)findViewById(R.id.text);

    tv.setText(getString(R.string.msg, token));
  }

  private PendingIntent buildPendingIntent() {
    return(PendingIntent.getActivity(this, 1337,
      new Intent(this, ResultActivity.class), 0));
  }
}

在这里，我将令牌显示在TextView中，因此您可以将其键入到其他设备上的SMS客户端中，并将令牌绑定到ResultActivity.

Here, I display the token in a TextView, so you can type it into an SMS client on some other device, and tie the token to a ResultActivity.

您指定的组件(例如ResultActivity)在其附加组件中接收实际的SMS消息，您可以使用Telephony.Sms.Intents.getMessagesFromIntent()来获取它:

Your designated component (e.g., ResultActivity) receives the actual SMS message in its extras, and you can use Telephony.Sms.Intents.getMessagesFromIntent() to get at it:
