【问题描述】：

我正在使用 github 操作通过 Heroku 部署我的第一个 web 应用程序。

我的代码：

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

if (!fireBaseAdmin) 
  throw new Error('The FIREBASE_SERVICE_ACCOUNT_CREDS environment variable was not found!');

fireBaseAdmin.initializeApp({
  "credential": fireBaseAdmin.credential.cert(JSON.stringify({
    "type": process.env.FIREBASE_TYPE,
    "project_id": process.env.FIREBASE_PROJECT_ID,
    "private_key_id": process.env.FIREBASE_PRIVATE_KEY_ID,
    "private_key": process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n'),
    "client_email": process.env.FIREBASE_CLIENT_EMAIL,
    "client_id": process.env.FIREBASE_CLIENT_ID,
    "auth_uri": process.env.FIREBASE_AUTH_URI,
    "token_uri": process.env.FIREBASE_TOKEN_URI,
    "auth_provider_x509_cert_url": process.env.FIREBASE_AUTH_PROVIDER,
    "client_x509_cert_url": process.env.FIREBASE_CLIENT
  }))
});

module.exports = fireBaseAdmin;

每个 .env 变量都存储在 Heroku 的 Config Vars 中。

来自 Heroku 的错误日志（我剥离了敏感令牌/密钥）：

我已尝试根据 Stack Overflow 上的各种帖子更新我的代码，但我没有成功解决错误。这是我一直参考的帖子的简短列表：

Deploying Firebase App with Service Account to Heroku (environment variables with dotenv) Authenticating with the Firebase Admin SDK using environment variable Node.js -Firebase Service Account Private Key won't parse Firebase: Failed to parse service account: 'project_id' must be set

任何帮助将不胜感激！

【解决方案1】：

cert() 方法需要serviceAccount.json 文件（字符串）的路径或ServiceAccount 对象。在这里，您正在输入一个字符串，因此它期望它是serviceAccount.json 的路径而不是字符串化凭据，因此您会收到错误FirebaseAppError: Failed to parse service account json file。试试这个：

fireBaseAdmin.initializeApp({
  credential: admin.credential.cert({
    type: process.env.FIREBASE_TYPE,
    project_id: process.env.FIREBASE_PROJECT_ID,
    private_key_id: process.env.FIREBASE_PRIVATE_KEY_ID,
    private_key: process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n'),
    client_email: process.env.FIREBASE_CLIENT_EMAIL,
    client_id: process.env.FIREBASE_CLIENT_ID,
    auth_uri: process.env.FIREBASE_AUTH_URI,
    token_uri: process.env.FIREBASE_TOKEN_URI,
    auth_provider_x509_cert_url: process.env.FIREBASE_AUTH_PROVIDER,
    client_x509_cert_url: process.env.FIREBASE_CLIENT
  }),
  databaseURL: `https://${process.env.FIREBASE_PROJECT_ID}.firebaseio.com/`
})

感谢您的快速回复！我进行了您的建议更改并包括： const admin = require('firebase-admin') 我现在收到以下错误：FirebaseAppError: Failed to parse private key: Error: Invalid PEM formatted message.
它没有用，但我认为我们越来越近了！我现在收到一条无效的 PEM 格式消息
@golembeskia 我会尝试 console.log(process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n')) 并检查它是否与下载的服务帐户 JSON 中的密钥相似
我在 Firebase 上重新生成了 private_key，现在一切正常。
@golembeskia 太棒了！如果我的回答有帮助，您可以点击复选标记图标接受它:)
