将 firebase privateKey 作为 Heroku 配置变量的问题 [英] Escaping issue with firebase privateKey as a Heroku config variable

问题描述

我正在尝试创建一个 Heroku 节点任务，该任务从 Firebase 读取数据并通过 console.log 对其进行记录.

I'm trying to create an Heroku node task that reads data from Firebase and console.log it.

我的节点脚本(位于/bin 目录内)是:

My node script (located inside the /bin directory) is:

require('dotenv').config({ silent: true });

var firebase = require('firebase');
firebase.initializeApp({
  serviceAccount: {
    projectId: process.env.fb_projectId,
    clientEmail: process.env.fb_clientEmail,
    privateKey: process.env.fb_privateKey
  },
  databaseURL: process.env.fb_databaseURL
})

console.log(process.env.fb_privateKey);

firebase.database().ref('tasks').once('value', function(snapshot) {
  console.log(snapshot.val());
  process.exit();
})

所有环境变量都是正确的，除了 fb_privateKey，因为它包含 个字符.

All env variables are correct, except fb_privateKey, since it contains characters.

我的本​​地 .env 文件和 Heroku 环境变量都包含一个名为 fb_privateKey 的键和一个带有 字符的字符串形式的值 -用 " 包围.

Both my local .env file and Heroku environment variables contains a key named fb_privateKey and a value as a string with characters - surrounded with ".

fb_privateKey="-----BEGIN PRIVATE KEY-----
MY-PRIVATE-KEY
-----END PRIVATE KEY-----
"

当我在本地运行脚本时，它会用新行+从 Firebase 返回的任务记录我的私钥.但是，当我在 Heroku 上运行它时， (heroku run myScript) 将我的私钥记录为 字符(作为单行)并且无法从中读取数据Firebase(可能是由于私钥错误).有什么想法吗?

When I run the script locally, it logs me the private key with new lines + the tasks that were returned from Firebase. However, when I run it on Heroku, (heroku run myScript) is logs me private key with characters (as a single line) and fails to read the data from Firebase (probably due to a bad private key). Any ideas?

推荐答案

我今天遇到了同样的问题.您需要通过将 \n 字符替换为 来清理读取的私钥.

I had the same problem today. You need to sanitize the read private key by replacing \n characters with .

admin.initializeApp({
  credential: admin.credential.cert({
    "projectId": process.env.FIREBASE_PROJECT_ID,
    "private_key": process.env.FIREBASE_PRIVATE_KEY.replace(/\n/g, '
'),
    "clientEmail": process.env.FIREBASE_CLIENT_EMAIL,
  }),
  databaseURL: process.env.FIREBASE_DATABASE_URL,
});
