通過兩個Firebase項目發送推送通知

Question

我正在使用Admin SDK for node.js發送推送通知。跟着tutorial並用這個鏈接給出的例子初始化了多個項目。

我需要知道如何使用node.js發送兩個項目的推送通知。使用下面的方法來發送通知基於它與默認的項目工作，但另一個項目得到錯誤，如下面

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)); 
    }); 
};

Answer 1

這裏是我的回答兩個項目

var ServiceAccount = require("./path your default app file.json"); 
var ServiceAccount1 = require("./path your second app file.json"); 

var serviceAppConfig = { 
    credential: firebaseAdmin.credential.cert(ServiceAccount), 
    databaseURL: "https://your firebase default app url" 
}; 

// Initialize the default app 
var serviceApp = firebaseAdmin.initializeApp(serviceAppConfig); 
//console.log(serviceApp.name); // "[DEFAULT]" 

// Retrieve services via the defaultApp variable... 
var serviceAuth = serviceApp.auth(); 
var serviceDatabase = serviceApp.database(); 
// Get the Messaging service for the default app 
global.serviceMessaging = firebaseAdmin.messaging(); 

var service1AppConfig = { 
    credential: firebaseAdmin.credential.cert(ServiceAccount1), 
    databaseURL: "https://your firebase url second app" 
}; 

// Initialize another app with a different config 
var service1App = firebaseAdmin.initializeApp(service1AppConfig, "App2 name"); 

// Use the otherApp variable to retrieve the other app's services 
var service1Auth = service1App.auth(); 
var service1Database = service1App.database(); 
// Get the Messaging service for a given app 
global.service1Messaging = firebaseAdmin.messaging(service1App);
