如何使用节点FCM发送通知。js到特定包名[重复]

Question

我已经在一个项目上工作了很长一段时间，我一直在使用Firebase。我已经实现了应用程序所需的所有Firebase功能。但我唯一的困惑是，FCM。

基本上，我有两个应用程序链接到Firebase项目。一个是消费者应用程序，另一个是管理员应用程序。现在，我正试图通知管理员何时有新订单到达，或何时有用户想与他们聊天。我已经成功地通过消费者应用程序使用node js和Firebase功能通知用户，但我无法通知管理员。这两个应用程序都有不同的软件包名称。但是，无论何时，一个应该通知管理员的触发器发生，它都会将通知发送给消费者应用程序而不是管理员应用程序。

我已经研究了很长一段时间，我唯一能收集到的是，我应该使用主题。但是我想知道，如果我使用主题，它是否仍然会将通知发送到消费者应用程序。因此，我需要询问是否可以使用node.js.向特定的包名称发送FCM通知，如果不可能，我如何实际实现它。提前多谢了

编辑1：这是我的索引。js代码：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.sendNotification = functions.database.ref('/notifications/{user_id}/{notification_id}').onWrite(event => {

  const user_id = event.params.user_id;
  const notification = event.params.notification_id;

  if(!event.data.val()){
  return console.log('A Notification has been deleted from Firebase');
}

console.log('The User ID is : ', user_id);

const fromUser = admin.database().ref(`/notifications/${user_id}/${notification}`).once('value');

return fromUser.then(fromUserResult => {

  const from_user_name = fromUserResult.val().from;
  const msg_type = fromUserResult.val().type;
  const message = fromUserResult.val().msg;
  console.log('Notification from: ', from_user_name);

  const deviceToken = admin.database().ref(`/Users/${user_id}`).once('value');
  console.log('Created deviceToken');
  return deviceToken.then (result => {

    const token_id = result.val().device_token;
    const order_id = result.val().order_id;
    console.log('Token ID: ', token_id);

    var payload;

    const token_id_aman = "eDYB-...ClU";

    if (msg_type == "text") {

      payload = {

        notification: {
        title : `New message from ${from_user_name}`,
        body: `${from_user_name}: ${message}`,
        icon: "default",
        tag: "text",
        sound: "default",
        click_action: "com.androidsword.techno.miniclip_TARGET_CHAT_NOTIFICATION"
        },
        data: {
          order_id: order_id,
          user_id: user_id,
          device_token: token_id
        }

        };

        if (from_user_name != "Admin") {

          payload = {

            notification: {
            title : `New message from ${from_user_name}`,
            body: `${from_user_name}: ${message}`,
            icon: "default",
            tag: "text",
            sound: "default",
            click_action: "com.androidsword.techno.adminminiclip_TARGET_NOTIFICATION"
            },
            data: {
              order_id: `${order_id}`,
              user_id:`${user_id}`,
              device_token:`${token_id}`
            }

            };

          return admin.messaging().sendToDevice(token_id_aman, payload).then(response => {
          console.log('This was a notification feature to Admin');
        });

      }

    }

    else if (msg_type == "status_changed") {

      payload = {

        notification: {
        title : `Order Status Changed`,
        body: `${message}`,
        icon: "default",
        tag: "status_changed",
        sound: "default",
        }
        };

    }

    else if (msg_type == "order") {

      payload = {

        notification: {
        title : `New Order`,
        body: `A new order has arrived`,
        icon: "default",
        tag: "order",
        sound: "default",
      }
        };

        return admin.messaging().sendToDevice(token_id_aman, payload).then(response => {
        console.log('This was a notification feature to Admin to inform about new order');
      });

    }


      return admin.messaging().sendToDevice(token_id, payload).then(response => {

      console.log('This was a notification feature');


    });

  });


});

});

您不能发送到某个包名称。您只能发送到主题或特定的设备id。
