Firebase云端功能总是超时 [英] Firebase cloud function always timeout

问题描述

问题是，即使我设法发送一个通知通知，请求总是超时。

这是我的脚本

  const functions = require（'firebase-functions'）; 
 const admin = require（'firebase-admin'）; 
 
 admin.initializeApp（functions.config（）。firebase）; 
 
 exports.friendRequestNotification = functions.https.onRequest（（req，res）=> {
 
 const senderId = req.query.senderId; 
 const recipientId = req.query.recipientId; 
 const getRecipientPromise = admin.database（）。ref（`/ players / $ {recipientId}`）.once（'value'）; 
 const getSenderPromise = admin.database （）.ref（`/ players / $ {senderId}`）.once（'value'）; 
 
 return Promise.all（[getRecipientPromise，getSenderPromise]）。then（results => { 
 $ b const const recipient = results [0]; 
 const sender = results [1]; 
 $ b $常量recipientToken = recipient.child（notificationsInfo / fcmToken）。 val（）; 
 const notificationAuthorization = recipient.child（notificationsInfo / wantsToReceiveNotifications）.val（）; 
 const recipientBadge = recipient.child（notificationsInfo / badgeNumber）.val（）; 
 const senderUsername = sender.child（username）。val（）; 
 
 const payload = {
通知：{
 title：`FriendRequest`，
 body：`您有来自$ {senderUsername}！`，
徽章的新的好友请求：（recipientBadge + 1）.toString（）
} 
}; 
 
 if（notificationAuthorization）{
 
 return admin.messaging（）。sendToDevice（recipientToken，payload）.then（response => {
 
 }）; 
 
 
 $ b return admin.database（）。ref（`/ players / $ {recipientId} / notificationsInfo / badgeNumber`）.setValue（recipientBadge + 1）; 
 
}）; 
 
}）; 
  

另外看来badgeNumber从来没有更新过，是关系到超时问题吗？

解决方案

HTTP触发的云功能就像Express应用程序一样工作 - 您有一个响应对象（ res ），当请求完成时，你需要使用它来发送一些东西。在这种情况下，它看起来像你可以做一些事情：

  return Promise.all（[
 / *。 （）=> {
 res.status（200）.send（'ok'）; 
}）。catch（err => {
 console.log（err.stack）; 
 res.status（500）.send（'error'）; 
}）; 
  

I'm exploring the firebase cloud functions and I'm trying to send a notifications with an http request.

The problem is that even if I manage to send the notification, the request always goes timeout.

Here's my script

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.friendRequestNotification = functions.https.onRequest((req, res) => {

    const senderId = req.query.senderId;
    const recipientId = req.query.recipientId;
    const getRecipientPromise = admin.database().ref(`/players/${recipientId}`).once('value');
    const getSenderPromise = admin.database().ref(`/players/${senderId}`).once('value');

    return Promise.all([getRecipientPromise, getSenderPromise]).then(results => {

        const recipient = results[0];
        const sender = results[1];

        const recipientToken = recipient.child("notificationsInfo/fcmToken").val();
        const notificationAuthorization = recipient.child("notificationsInfo/wantsToReceiveNotifications").val();
        const recipientBadge = recipient.child("notificationsInfo/badgeNumber").val();
        const senderUsername = sender.child("username").val();

        const payload = {
            notification: {
              title: `FriendRequest`,
              body: `You have a new friend request from ${senderUsername}!`,
              badge: (recipientBadge+1).toString()
            }
        };

        if (notificationAuthorization) {

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

            });

        }

        return admin.database().ref(`/players/${recipientId}/notificationsInfo/badgeNumber`).setValue(recipientBadge+1);

    });

});

Plus It seems that the badgeNumber in never updated, is that related to the timeout issue?

解决方案

HTTP-triggered Cloud Functions work just like Express apps -- you have a response object (res) that you need to use to send something when the request is done. In this case, it looks like you could do something like:

return Promise.all([
  /* ... */
]).then(() => {
  res.status(200).send('ok');
}).catch(err => {
  console.log(err.stack);
  res.status(500).send('error');
});
