Question

我想将推送通知发送到firebase中的特定用户组。例如，在宠物字段中的应用程序的注册表单中，用户将宠物类型设置为dog.now我想将推送通知发送到有狗的用户。有人请建议我怎么用firebase做这个？

Answer 1

首先，您必须在分析中指定哪些宠物包含狗。

此屏幕截图是我的示例

Firebase云消息传递（FCM）提供三种不同类型的目标，允许您将推送通知发送到指定的用户组。这三种类型的目标是：用户细分，主题和单个设备。

在用户细分中，您可以选择用于发送推送通知的应用。点击＆＃34; AND＆＃34;添加更多过滤规则。

在观众中 - 您可以向宠物狗的用户发送推送通知。

尝试使用此代码：

public class NotifyListAdapter extends BaseAdapter implements Constants {

        private Activity activity;
        private LayoutInflater inflater;
        private List<Notify> notifyList;

        ImageLoader imageLoader = App.getInstance().getImageLoader();

        public NotifyListAdapter(Activity activity, List<Notify> notifyList) {

            this.activity = activity;
            this.notifyList = notifyList;
        }

        @Override
        public int getCount() {

            return notifyList.size();
        }

        @Override
        public Object getItem(int location) {

            return notifyList.get(location);
        }

        @Override
        public long getItemId(int position) {

            return position;
        }

        static class ViewHolder {

            public TextView notifyTitle;
            public TextView notifyTimeAgo;
            public CircularImageView notifyAuthor;
            public CircularImageView notifyType;

        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            ViewHolder viewHolder = null;

            if (inflater == null) {

                inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            }

            if (convertView == null) {

                convertView = inflater.inflate(R.layout.notify_list_row, null);

                viewHolder = new ViewHolder();

                viewHolder.notifyAuthor = (CircularImageView) convertView.findViewById(R.id.notifyAuthor);
                viewHolder.notifyType = (CircularImageView) convertView.findViewById(R.id.notifyType);
                viewHolder.notifyTitle = (TextView) convertView.findViewById(R.id.notifyTitle);
                viewHolder.notifyTimeAgo = (TextView) convertView.findViewById(R.id.notifyTimeAgo);

                convertView.setTag(viewHolder);

            } else {

                viewHolder = (ViewHolder) convertView.getTag();
            }

            if (imageLoader == null) {

                imageLoader = App.getInstance().getImageLoader();
            }

            viewHolder.notifyTitle.setTag(position);
            viewHolder.notifyTimeAgo.setTag(position);
            viewHolder.notifyAuthor.setTag(position);
            viewHolder.notifyType.setTag(position);
            viewHolder.notifyAuthor.setTag(R.id.notifyAuthor, viewHolder);

            final Notify notify = notifyList.get(position);

            viewHolder.notifyType.setVisibility(View.GONE);

            if (notify.getType() == NOTIFY_TYPE_LIKE) {

                viewHolder.notifyTitle.setText(activity.getText(R.string.label_gcm_like));
                viewHolder.notifyType.setImageResource(R.drawable.notify_like);

                viewHolder.notifyAuthor.setImageResource(R.drawable.notify_like);

            } else if (notify.getType() == NOTIFY_TYPE_COMMENT) {

                viewHolder.notifyTitle.setText(activity.getText(R.string.label_gcm_comment));
                viewHolder.notifyType.setImageResource(R.drawable.notify_comment);

                viewHolder.notifyAuthor.setImageResource(R.drawable.notify_comment);

            } else if (notify.getType() == NOTIFY_TYPE_COMMENT_REPLY) {

                viewHolder.notifyTitle.setText(activity.getText(R.string.label_gcm_comment_reply));
                viewHolder.notifyType.setImageResource(R.drawable.notify_reply);

                viewHolder.notifyAuthor.setImageResource(R.drawable.notify_reply);

            } else {

                viewHolder.notifyTitle.setText(activity.getText(R.string.label_follow_you));
                viewHolder.notifyType.setImageResource(R.drawable.notify_follower);

                viewHolder.notifyAuthor.setImageResource(R.drawable.notify_follower);
            }

            viewHolder.notifyTimeAgo.setText(notify.getTimeAgo());

            return convertView;
        }
    }

Answer 3

您通常会使用主题消息传递。使用主题，您的用户可以订阅主题pet_type_dog。在Android上，这将是这样的：

FirebaseMessaging.getInstance().subscribeToTopic("pet_type_dog");

然后您向宠物类型等于狗的所有用户发送消息。使用JavaScript Admin SDK，如下所示：

admin.messaging().sendToTopic("pet_type_dog", {
  notification: {
    title: "Monday message for dog lovers",
    body: "Today's special dog is Dee Dee from SF."
  }
}).then(function(response) {
    // See the MessagingTopicResponse reference documentation for the
    // contents of response.
    console.log("Successfully sent message:", response);
  })
  .catch(function(error) {
    console.log("Error sending message:", error);
  })
