使用fcm節點模塊在nodejs中發送推送通知

Question

我想在設備上發送推送通知我有設備ID，如何在該設備上發送通知。

Answer 1

你可以使用nodejs包node-gcm 更多請檢查這個鏈接，你會更多和解決你的問題。

node package1

或 node package2

Answer 2

我已經使用FCM的通知發送給用戶。我使用了Mongodb，Nodejs和fcm-push節點模塊。

請參閱代碼，希望它能幫助你。

deviceModel.js：

var mongoose = require('mongoose'); 
var Schema = require('mongoose').Schema; 

var schema = new Schema({ 
    userId: { type: Schema.Types.ObjectId }, 
    userType: { type: String }, 
    deviceType: { type: String, required: true, enum: ['apn', 'gcm'] }, 
    deviceId: { type: String, required: true }, 
    timestamp: { type: Date, default: Date.now } 
}); 

module.exports = mongoose.model('Device', schema); 

push.js：

var pushModule = require('./push'); 
var DeviceModel = require('./DeviceModel'); 
var highland = require('highland'); 
var FCM = require('fcm-push'); 
var serverKey = config.get('fcmServerKey'); 
var fcm = new FCM(serverKey); 
var _ = require('lodash'); 


/** 
* Handle fcm push results and updates/invalidates device ids. 
* 
* @param {String[]} deviceIds - array of device ids used in send. 
* @param {Object} fcmResponse - fcm send response. 
*/ 
function handleFcmSendResult(deviceIds, fcmResponse) { 

    // fcm results 
    var results = fcmResponse.results; 

    // changes for deviceIds 
    var fcmUpdated = []; 
    var fcmDeleted = []; 

    // process results 
    for (var i = 0; i < results.length; i++) { 

     var oldId = deviceIds[i]; 
     var deviceResult = results[i]; 
     var msgId = deviceResult.message_id; 
     var newId = deviceResult.registration_id; 

     if (_.isString(msgId) && _.isString(newId)) { 
      // If registration_id is set, replace the original ID with the new value 
      fcmUpdated.push({ oldId: oldId, newId: newId }); 
     } else { 
      // Otherwise, get the value of error 
      var e = deviceResult.error; 

      if (e === 'Unavailable') { 
       winston.warn('Push: FCM: Feedback: device unavailable: %s.', oldId); 
      } else if (e === 'NotRegistered' || e === 'InvalidRegistration') { 
       // delete invalid devices 
       fcmDeleted.push(oldId); 
      } 
     } 
    } 

    // apply changes, in bulk 
    var bulkOp = DeviceModel.collection.initializeUnorderedBulkOp(); 


    if (fcmUpdated.length > 0) { 
     fcmUpdated.forEach(function (upd) { 
      bulkOp.find({ deviceId: upd.oldId }).update({ deviceId: upd.newId, timestamp: Date.now() }); 
     }); 

     // those old ids that are updated, need not be deleted 
     fcmDeleted = _.difference(fcmDeleted, _.map(fcmUpdated, _.property('oldId'))); 
    } 

    if (fcmDeleted.length > 0) { 
     bulkOp.find({ deviceId: { '$in': fcmDeleted } }).remove(); 
    } 

    console.log(bulkOp); 
    // run bulk op 
    bulkOp.execute(); 
} 


/**

// Send notification test function 
var sendNotification = function() { 
    var payload = { 
     "updatedAt": "2017-06-17T06:12:42.975Z", 
     "message": "this is notification message", 
     "typeId": "591452ecad4c6b71bed61089",
