在本地 Firebase 中，如何为当前环境设置一个 projectId？

Question

我正在尝试将一些测试数据写入本地版本的 Firebase。我在我的 .env.local（和 .env.development 文件）...

中定义了这些变量

REACT_APP_MB_ACCESS_TOKEN="accesstoken"
ALGOLIA_APP_ID="appid"
ALGOLIA_API_KEY="apikey"
NODE_ENV="development"
FIREBASE_EMULATOR_HOST_VAR=localhost:9000
FIRESTORE_EMULATOR_HOST=localhost:8080
GCLOUD_PROJECT=mutualaid-123f6

我进行了以下设置（通过 npm 运行 dev:upload）将虚拟数据上传到我的本地 Firebase ...

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

const data = require("./data.json");
let serviceAccount = process.env.FIREBASE_SECRET;
...

  require("dotenv").config();
  admin.initializeApp();
  db = admin.firestore();
...

async function upload(data, path) {
  console.log("starting ...");
  return await db
    .doc(path.join("/"))
    .set(data)
    .then(() => console.log(`Document ${path.join("/")} uploaded.`))
    .catch((e) => {
      console.error(`Could not write document ${path.join("/")}.`);
      console.log(e);
    });

或我的 data.json 文件中的所有数据（示例如下）。我还需要配置什么才能将这些数据导入我的本地 Firebase？

{
  "organizations": {
    "1": {
      "missions": {
        "aaf3c03c33ecf79e3d7ffddf401c01f0": {
          "status": "started",
          "missionDetails": {
            "dummy": "This is only here because upload modules did not understand that we want this to be a field",
            "needs": [
              {
                "name": "Fruits & Veggies Medley",
                "quantity": 1
              }
            ]
          },
          "uid": "aaf3c03c33ecf79e3d7ffddf401c01f0",
          "deliveryConfirmationImage": "",
          "feedbackNotes": "",
          "groupUid": "Daly City 2020/03/05",
          "organizationUid": "1",
          "volunteerDisplayName": "Michael Williams",
          "deliveryWindow": {
            "timeWindowType": "as soon as possible",
            "startTime": "06/03/2020, 10:40:57"
          },

Answer 1

看起来您可能遗漏了 process.env.FIREBASE_SECRET（除非您故意不包含它，因为它是私钥）。我还应该指出 .env* 文件不适合存储私钥，因为它们捆绑在您的应用程序代码中并且可以公开访问。

您可以通过多种方式初始化管理 SDK。它们在 Add the Firebase Admin SDK to your server reference guide. It looks like you are attempting to initialise the SDK without parameters, which is covered here 上有概述。基本上，您需要设置一个名为 FIREBASE_CONFIG 的环境变量（通过终端中的 export，而不是 .env 文件），它是包含您的配置的 JSON 文件的路径信息或者是包含您的配置信息的 JSON 对象。

祝你好运！

Answer 2

您还没有将配置对象传递给 admin.initializeApp

由于您使用 dotenv 加载 env 文件，因此您可以创建一个包含 env 详细信息的配置对象，例如

const config = {
    type: "service_account",
    project_id: "xxx",
    credential: 'your credentials'
};

require("dotenv").config();
  admin.initializeApp({config});
  db = admin.firestore();

如果您没有将任何配置传递给 initializeApp，那么您需要定义它 FIREBASE_CONFIG env 对象。

根据 documentation:

The SDK can also be initialized with no parameters. In this case, the SDK uses Google Application Default Credentials and reads options from the FIREBASE_CONFIG environment variable. If the content of the FIREBASE_CONFIG variable begins with a { it will be parsed as a JSON object. Otherwise the SDK assumes that the string is the name of a JSON file containing the options.
