通过推送通知与邮递员发送可点击的链接

标签： android url push-notification notifications postman

我看到这不是一个不常见的主题，我试图阅读其他帖子，但我不知道如何将其应用到我的应用程序。在我的应用程序中，我通过PostMan发送推送通知，然后根据我设置的标志打开不同的活动。我想发送不同的通知链接，所以当用户点击它时，它会打开一个浏览器。换句话说，我希望在通知专用于活动时同时拥有活动标志，并在通知包含特定链接时使用URL。

我从previous post的答案中看到，一个解决方案就是这样设定的意图：

Intent notificationIntent = new Intent(Intent.ACTION_VIEW);

notificationIntent.setData(Uri.parse("http://www.google.com"));
PendingIntent contentIntent = PendingIntent.getActivity(contexta, 0, notificationIntent, 0);
notification.setLatestEventInfo(contexta, contentTitle, contentText, contentIntent);
mNotificationManager.notify(970970, notification);

但据我所知，默认设置为www.google.com。我怎样才能打开PostMan发送的特定链接？我假设我需要以某种方式将上述代码引入我的IF条件（如在here中），但是如何？

我对PushNotifications的代码如下：

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.RemoteMessage;

import org.json.JSONException;
import org.json.JSONObject;

public class MyFirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {
  private static final String TAG = "FirebaseMessagingServic";

  public MyFirebaseMessagingService() {}

  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
      Log.d(TAG, "Message data payload: " + remoteMessage.getData());
      try {
        JSONObject data = new JSONObject(remoteMessage.getData());
        String jsonMessage = data.getString("extra_information");
        Log.d(TAG, "onMessageReceived: \n" +
          "Extra Information: " + jsonMessage);
      } catch (JSONException e) {
        e.printStackTrace();
      }
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
      String title = remoteMessage.getNotification().getTitle(); //get title
      String message = remoteMessage.getNotification().getBody(); //get message
      String click_action = remoteMessage.getNotification().getClickAction(); //get click_action

      Log.d(TAG, "Message Notification Title: " + title);
      Log.d(TAG, "Message Notification Body: " + message);
      Log.d(TAG, "Message Notification click_action: " + click_action);

      sendNotification(title, message, click_action);
    }
  }

  @Override
  public void onDeletedMessages() {

  }

  private void sendNotification(String title, String messageBody, String click_action) {
    Intent intent;
    if (click_action.equals("EVENIMENTE")) {
      intent = new Intent(this, Evenimente.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    } else if (click_action.equals("PRIMA_PAGINA")) {
      intent = new Intent(this, MainScreenActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    } else {
      intent = new Intent(this, MainScreenActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    }

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */ , intent,
      PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
      .setSmallIcon(R.drawable.app_logo_final)
      .setContentTitle("App")
      .setContentText(messageBody)
      .setAutoCancel(true)
      .setLights(Color.RED, 3000, 3000)
      .setSound(defaultSoundUri)
      .setVibrate(new long[] {
        1000,
        1000,
        1000,
        1000,
        1000
      })
      .setContentIntent(pendingIntent);


    NotificationManager notificationManager =
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */ , notificationBuilder.build());
  }
}

所以，我有click_action设置，正如其他帖子中也提到的那样，所以我猜这是从PostMan发送链接的地方，但是如何？有人可以帮我这个吗？谢谢！

让我解释几件事。意图可以分配给他们的动作，活动可以有意图过滤器。意图过滤器就像是说，无论何时系统广播这种意图，我都是一个活动，我愿意处理它。这些intent过滤器写在清单文件中。所以你的活动看起来像这样。这种意图称为隐含意图。

<activity
    android:name=".MainActivity" >
    <intent-filter>
        <action android:name="com.example.MY_ACTION" />
    </intent-filter>
</activity>

当我想从一个隐含的意图开始这个活动时，它将以这种方式完成。

Intent intent = new Intent("com.example.MY_ACTION");

现在回答您的问题，您可以改进代码中的某些内容。您可以在Manifest文件中的活动中包含intent过滤器。 因此，您不必放置if条件。

就像您的自定义意图操作一样，浏览器的默认操作为Intent.ACTION_VIEW。现在，您只需从邮递员的邮件中发送正确的操作，为这些操作创建隐式意图，您就完成了。

import android.app.NotificationManager;
import android.app.PendingIntent;

import android.content.Intent;
import android.graphics.Color;
import android.media.RingtoneManager;

public class MyFirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService {
  private static final String TAG = "FirebaseMessagingServic";

  public MyFirebaseMessagingService() {}

  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
      Log.d(TAG, "Message data payload: " + remoteMessage.getData());
      try {
        JSONObject data = new JSONObject(remoteMessage.getData());
        String jsonMessage = data.getString("extra_information");
        Log.d(TAG, "onMessageReceived: \n" +
          "Extra Information: " + jsonMessage);
      } catch (JSONException e) {
        e.printStackTrace();
      }
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
      String title = remoteMessage.getNotification().getTitle(); //get title
      String message = remoteMessage.getNotification().getBody(); //get message
      String click_action = remoteMessage.getNotification().getClickAction(); //get click_action
      String uri = remoteMessage.getNotification().getLink(); //parsing url

      Log.d(TAG, "Message Notification Title: " + title);
      Log.d(TAG, "Message Notification Body: " + message);
      Log.d(TAG, "Message Notification click_action: " + click_action);
      Log.d(TAG, "Message Notification uri: " + uri);

      sendNotification(title, message, click_action, uri);
    }
  }

  @Override
  public void onDeletedMessages() {

  }

  private void sendNotification(String title, String messageBody, String click_action, Uri uri) {
    Intent intent;
    /*if (click_action.equals("EVENIMENTE")) {
      intent = new Intent(this, Evenimente.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    } else if (click_action.equals("PRIMA_PAGINA")) {
      intent = new Intent(this, MainScreenActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    } else {
      intent = new Intent(this, MainScreenActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    }*/

    //If conditions can be replaced with this. Not sure why wrote last else condition. If you want to start MainScreenActivity when there is no action or the action is PRIMA_PAGINA, you could simply write direct else.
    if(uri != null) {
      intent = new Intent(Intent.ACTION_VIEW);
      intent.setData(uri);
    } else {
      intent = new Intent(click_action);
      //click_action will be "EVENIMENTE"/"com.example.EVENIMENTE" for Evenimente.class, PRIMA_PAGINA for MainScreenActivity.class
    }

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */ , intent,
      PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
      .setSmallIcon(R.drawable.app_logo_final)
      .setContentTitle("App")
      .setContentText(messageBody)
      .setAutoCancel(true)
      .setLights(Color.RED, 3000, 3000)
      .setSound(defaultSoundUri)
      .setVibrate(new long[] {
        1000,
        1000,
        1000,
        1000,
        1000
      })
      .setContentIntent(pendingIntent);


    NotificationManager notificationManager =
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */ , notificationBuilder.build());
  }
}

如上所述，为您的活动更新并添加intent-filter。意图过滤器应该与您要在fcm消息中发送的click_action完全相同。
