Firebase超時的雲端函數

Question

獲取數據庫數據的簡單雲端功能不起作用。

getusermessage()不工作

錯誤：

Function execution took 60002 ms, finished with status: 'timeout'

Index.JS用於獲取數據庫的結果。

const functions = require('firebase-functions'); 
const admin = require('firebase-admin'); 
admin.initializeApp(functions.config().firebase); 
const cors = require('cors')({origin: true}); 

// Take the text parameter passed to this HTTP endpoint and insert it into the 
// Realtime Database under the path /messages/:pushId/original 
exports.addMessage = functions.https.onRequest((req, res) => { 
    // Grab the text parameter. 
    const original = req.query.text; 
    // Push the new message into the Realtime Database using the Firebase Admin SDK. 
    admin.database().ref('/messages').push({original: original}).then(snapshot => { 
    // Redirect with 303 SEE OTHER to the URL of the pushed object in the Firebase console. 
    res.redirect(303, snapshot.ref); 
    }); 
}); 

// Listens for new messages added to /messages/:pushId/original and creates an 
// uppercase version of the message to /messages/:pushId/uppercase 
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original') 
    .onWrite(event => { 
     // Grab the current value of what was written to the Realtime Database. 
     const original = event.data.val(); 
     console.log('Uppercasing', event.params.pushId, original); 
     const uppercase = original.toUpperCase(); 
     // You must return a Promise when performing asynchronous tasks inside a Functions such as 
     // writing to the Firebase Realtime Database. 
     // Setting an "uppercase" sibling in the Realtime Database returns a Promise. 
     return event.data.ref.parent.child('uppercase').set(uppercase); 
    }); 

var db = admin.database(); 
exports.getUserMessage = functions.https.onRequest((req, res) => { 
var query = db.ref("messages").orderByKey(); 
query.once("value") 
    .then(function(snapshot) { 
    snapshot.forEach(function(childSnapshot) { 
     var key = childSnapshot.key; 
     // childData will be the actual contents of the child 
     var childData = childSnapshot.val(); 
    }); 
}); 
}); 

什麼是O做錯了？

你沒有說你的三個函數中哪一個函數超時，但我會猜測哪一個函數會超時。您的HTTPS功能getUserMessage未生成對客戶端的響應。雲功能將等待60秒（默認情況下）以生成響應，如果不響應，它將終止該功能並將該消息留在日誌中。

HTTPS函數中的每條代碼路徑都會生成一些對客戶端的響應。
