Node.js 使用两个Firebase项目发送推送通知

我正在使用node.js的AdminSDK发送推送通知。遵循并使用与此链接类似的示例初始化多个项目

我需要知道如何使用with node.js发送两个项目的推送通知。使用以下方法发送通知：两个项目使用默认项目，但另一个项目出现如下错误

exports.send_test_mailer = function(req, res) {
  // Default project
  var registrationToken = ["f-vRsDouUFQ:APA91bGktVzu3WjKGqeXqdiYPI8B0lQXs34TkJS4p7LaMiFGfp5LdfB1ZjEhO3CY5ci92apqgt1hEJY0ml11C4hxYUaPfDl7PeDHhcmDGur0JUx5l3M2mLEj30epwRBWVsE4xMSTls4f"];
  var payload = {
    notification: {
      title: "driver app",
      body: "driver app push notfications on the day."
    },
    data: {
      score: "850",
      time: "2:45"
    }
  };
  firebaseAdmin.messaging().sendToDevice(registrationToken, payload)
    .then(function(response) {
    console.log("Successfully sent message driver:", JSON.stringify(response));
  })
  .catch(function(error) {
    console.log("Error sending message driver:", JSON.stringify(error));
  });
  // Second project
  var registrationTokens = ["dzXRXUMIB5w:APA91bHSArtroO8M33IHxaslQTugTcEzJcfkbsXEhwbXbvVzBws-aqG4aqKNr37j8WpZev7lolX7cFQlAKYZ1QV_EgC6zTGeT41n3lvSpcDyBg6t4SZZaoPe7nUO9sbdcXA2KDguxAbk"];
  var payloads = {
    notification: {
      title: "customer app",
      body: "customer app push notfications on the day."
    },
    data: {
      score: "850",
      time: "2:45"
    }
  };
  firebaseAdmin.messaging().sendToDevice(registrationTokens, payloads)
    .then(function(response) {
    console.log("Successfully sent message customer:", JSON.stringify(response));
  })
  .catch(function(error) {
    console.log("Error sending message customer:", JSON.stringify(error));
  }); 
};

谢谢我需要

firebaseAdmin.messaging（service1App）@Mr.B。我可以投票给你答案，它工作得很好。
