在Firebase云函数中,我在实时数据库的读写操作上遇到了admin-firebase的访问被拒绝的问题。此处https://github.com/firebase/firebase-functions/issues/16并未解决我的问题,App engine默认服务帐号权限设置为编辑器。
我还配置了Node.js管理员sdk和服务账户密钥,这里一切正常运行。
我已经在数据库中设置了默认安全规则。
以下是示例函数。

以下是示例函数。
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
admin.database.enableLogging(true);
//event fires properly
exports.sendNotif = functions.database.ref('/messages/{roomId}/{msgKey}')
.onWrite(event => {
const message = event.data.val().text;
//this executes as expected
console.log(message);
//here I am getting access denied and consequently function timeout after 60 seconds.
return admin.database().ref('/userFCMTokens').once('value')
.then(snap => console.log(snap.val()));
});
以下是来自 Firebase 实时数据库的日志片段:

以下简述无需登录实时数据库:
2017-06-08T15:26:23.164035495Z D sendNotif: Function execution started
2017-06-08T15:26:23.164076543Z D sendNotif: Billing account not configured. External network is not accessible and quotas are severely limited. Configure billing account to remove these restrictions
2017-06-08T15:26:23.539Z I sendNotif: message console logged
2017-06-08T15:27:23.165321703Z D sendNotif: Function execution took 60002 ms, finished with status: 'timeout'
为什么我不能在云函数中使用管理员帐户进行读写操作?
