Ios 节点通过firebase向应用程序发送APN
嗨,我想将APN发送到我的应用程序。我已成功生成通知并将其发送到我的应用程序 我的问题是,服务器发送通知的频率相当高。我猜我的脚本算法有问题 我想做什么: 我希望每次在帖子中有评论时都将通知发送到设备。我想从Firebase数据库中显式获取用户名和注释 我正在附加服务器脚本:Ios 节点通过firebase向应用程序发送APN,ios,node.js,firebase-realtime-database,apple-push-notifications,Ios,Node.js,Firebase Realtime Database,Apple Push Notifications,嗨,我想将APN发送到我的应用程序。我已成功生成通知并将其发送到我的应用程序 我的问题是,服务器发送通知的频率相当高。我猜我的脚本算法有问题 我想做什么: 我希望每次在帖子中有评论时都将通知发送到设备。我想从Firebase数据库中显式获取用户名和注释 我正在附加服务器脚本: var firebase = require("firebase"); var once = require("once"); const apn = require('apn'); var config = { api

要初始化应用程序,我认为最好使用可以通过Firebase控制台下载的serviceAccountKey文件,而不是直接将密钥写入代码中:
const functions = require('firebase-functions');
var admin = require('firebase-admin');
var serviceAccount = require("./serviceAccountKey.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "YOUR_DATABASE_URL_GOES_HERE"
});
当然,您需要在此处替换为您自己的数据库url,并确保serviceAccountKey.json文件位于functions文件夹中
但是,我认为您需要稍微重新构造数据库,以便更容易在服务器端检索您的ID,例如,它可能如下所示:
root/
| ....
|
|
|___ posts/
| |___ postID
| |___ authorId : ...
| |___ caption : ...
| |___ comments
| |___ commentID
| |___ senderId: ...
| |___ text: ...
| ...
|
|
|___ users/
| |___ userID
| |___ name : ...
| |___ email : ...
| |___ notificationTokens
| |___ token1 : true
| |___ token2 : true
| ...
然后,只要comments节点中有新的写入事件,就可以创建并使用该函数在通知节点中写入通知对象:
exports.createPostCommentedNotification = functions.database.ref('/posts/{postID}/comments/{commentID}').onWrite(event => {
const data = event.data;
if(data == undefined || !data.val()) { return; }
const postID = event.params.postID;
const commentID = event.params.commentID;
const getCommentSender = admin.database().ref(`/posts/${postID}/comments/${commentID}`).once('value');
const getPostAuthor = admin.database().ref(`/posts/${postID}`).once('value');
return Promise.all([getCommentSender, getPostAuthor]).then(results => {
const commentSenderData = results[0];
const postAuthorData = results[1];
const commentSenderId = commentSenderData.val().senderId;
const postAuthorId = postAuthorData.val().authorId;
if(commentSenderId == postAuthorId) {
return;
};
const notificationID = admin.database().ref().push().key;
const timestamp = Date.now()
const getSenderProfilePromise = admin.auth().getUser(commentSenderId);
return Promise.all([getSenderProfilePromise]).then(results => {
// Note that when you create a user account you would need to set the displayName of the user using the updateProfile() method, otherwise you would need to retrieve the senderName in a different way:)
const senderData = results[0]
const senderName = senderData.providerData[0].displayName
var notificationData = {
senderName: senderName,
notificationTimestamp: timestamp
};
var updates = {};
updates['/notifications/' + postAuthorId + '/' + notificationID] = notificationData;
admin.database().ref().update(updates);
});
});
});
然后,您将创建另一个函数,以便在通知节点中添加新的通知对象时,使用您的用户令牌实际发送推送通知,如下所示:
exports.sendPushNotifications = functions.database.ref('/notifications/{receiverId}/{notificationId}').onWrite(event => {
const data = event.data;
if(data == undefined || !data.val()) { return; }
const receiverId = event.params.receiverId;
const notificationId = event.params.notificationId;
const getDeviceTokensPromise = admin.database().ref(`/users/${receiverId}/notificationTokens`).once('value');
const getMessageContentPromise = admin.database().ref(`/notifications/${receiverId}/${notificationId}/notificationType`).once('value');
const getSenderPromise = admin.database().ref(`/notifications/${receiverId}/${notificationId}/senderName`).once('value');
return Promise.all([getDeviceTokensPromise, getSenderPromise]).then(results => {
const tokensSnapshot = results[0];
const senderSnapshot = results[1];
const sender = senderSnapshot.val()
if (!tokensSnapshot.hasChildren()) {
return console.log('There are no notification tokens to send to.');
}
const payload = {
notification: {
title: `${sender}`,
body: 'Someone commented on your post',
badge: '1'
}
};
var options = {
priority: "high",
timeToLive: 60 * 60 * 24,
mutable_content : true,
content_available : true,
category : 'reminder'
};
const tokens = Object.keys(tokensSnapshot.val());
return admin.messaging().sendToDevice(tokens, payload, options).then(response => {
const tokensToRemove = [];
response.results.forEach((result, index) => {
const error = result.error;
if (error) {
console.error('Failure sending notification to', tokens[index], error);
if (error.code === 'messaging/invalid-registration-token' ||
error.code === 'messaging/registration-token-not-registered') {
tokensToRemove.push(tokensSnapshot.ref.child(tokens[index]).remove());
}
}
});
return Promise.all(tokensToRemove);
});
});
});
如果你有任何问题,请告诉我 这看起来很完美。不过我的剧本出了个错误。谢谢你的帮助。完成集成后,我将更新您。干杯,太棒了!是的,只要让我知道一切是否顺利,并随时问我是否可以帮助你;)祝你的项目好运!嘿,我可能在一个问题上卡住了。我们在这里使用云函数。这似乎对我不起作用。我发现
Firebase配置变量不可用。请使用最新版本的Firebase CLI部署此功能。
。尽管我已经安装了firebase CLI。我遗漏了什么吗?我正在使用cloud9,但它似乎没有安装firebase CLI。希望你对我的两个问题都有一个解决方案。嗯,当你在终端中输入npm-v时,你会得到什么?
