Question

我想使用firebase admin SDK来让我的节点服务器自由访问我的数据库。这是我的index.js文件夹中的functions的代码：

const functions = require("firebase-functions");
const admin = require("firebase-admin");

// Initialize app
admin.initializeApp({
  credential: admin.credential.cert("logininfo.json"),
  databaseURL: "https://thenameofmydatabase.firebaseio.com/",
  databaseAuthVariableOverride: {
    uid: "nameserver"
  }
});

在同一文件夹中，我有我的logininfo.json，它看起来像这样（出于明显的原因检查了密钥）：

{
  "type": "service_account",
  "project_id": "...",
  "private_key_id": "...",
  "private_key": "...",
  "client_email": "...",
  "client_id": "...",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "..."
}

但是，尝试部署到Firebase托管时出现错误Failed to parse certificate key file: Error: ENOENT: no such file or directory。

如何解决此问题，有没有更安全/更优雅的方式来解决此问题？我可以在Firebase托管中的某个地方更改GOOGLE_APPLICATION_CREDENTIALS变量吗？

它可以通过2种不同的方式完成：

按路径：

    const functions = require("firebase-functions");
    const admin = require("firebase-admin");
    const serviceAccount = require("path/to/logininfo.json");

    // Initialize app
    admin.initializeApp({
      credential: admin.credential.cert(serviceAccount),
      databaseURL: "https://thenameofmydatabase.firebaseio.com/",
      databaseAuthVariableOverride: {
        uid: "nameserver"
      }
    });

按对象：

const functions = require("firebase-functions");
        const admin = require("firebase-admin");

        // Initialize app
        admin.initializeApp({
          credential: admin.credential.cert({
               "type": "service_account",
               "project_id": "...",
               "private_key_id": "...",
               "private_key": "...",
               "client_email": "...",
               "client_id": "...",
               "auth_uri": "https://accounts.google.com/o/oauth2/auth",
               "token_uri": "https://oauth2.googleapis.com/token",
               "auth_provider_x509_cert_url": 
               "https://www.googleapis.com/oauth2/v1/certs",
               "client_x509_cert_url": "..."
        }),
          databaseURL: "https://thenameofmydatabase.firebaseio.com/",
          databaseAuthVariableOverride: {
            uid: "nameserver"
          }
        });

如何在Node JS中加载Firebase管理密钥？
