[英]how to get all documents from Firestore and make a loop (Cloud Functions)
我正在嘗試使用雲 function 使用 Javascript 訪問我的 Firestore 數據庫中的數據我需要循環我擁有的所有文檔(我有 7 個文檔),但它只返回第一個文檔並將其打印在日志中,我不不知道為什么。 這是我的代碼
const functions = require("firebase-functions"); const admin = require('firebase-admin'); admin.initializeApp(functions.config().firebase); // Create and deploy your first functions // https://firebase.google.com/docs/functions/get-started exports.helloWorld = functions.https.onRequest(async (request, response) => { functions.logger.info("Hello logs", {structuredData: true}); //loop on the document const facultyRef = await admin.firestore().collection('faculty').get().then((querySnapshot) => { querySnapshot.forEach((doc) => { response.send("Hello Firebase"); //print the doc id in the logs functions.logger.info(doc.id); }); }); });
注意:它在頁面中打印“Hello Firebase”,並在日志中打印“hello logs”和第一個文檔 Id
通過執行response.send()
,您實際上是在終止您的雲 Function,請參閱 文檔。
如果要記錄所有文檔 ID,請執行以下操作:
exports.helloWorld = functions.https.onRequest(async (request, response) => {
functions.logger.info("Hello logs", { structuredData: true });
const facultyQuerySnapshot = await admin.firestore().collection('faculty').get();
facultyQuerySnapshot.forEach((doc) => {
//print the doc id in the logs
functions.logger.info(doc.id);
});
// We terminate the Function AFTER the loop has completed
response.send("Hello Firebase");
});
