如何使用 firebase admin sdk 将图像上传到 firebase 存储？

Question

我在这里使用 Next.js。我需要将图像上传到我的 Firebase 存储。但它给了我大量的错误。好的，它给了我 1 个错误。

初始化firebase admin sdk

// firebase.js
import * as admin from "firebase-admin";
import serviceAccount from "./firebase.serviceAccount.json";

if (!admin.apps.length) {
    admin.initializeApp({
        credential: admin.credential.cert(serviceAccount),
        databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL
    });
}

const firestore = admin.firestore();
const storage = admin.storage();

c
export { firestore, storage };

上传图片

// route.js
import {  storage } from "../../firebase";

const router = async (req, res) => {
    // ...
    // Getting file from api request and so on...
    // ...

    const file = <an instance of File object>;

    const currentTime = Date.now();
    const fileName = file.name;

    const fileTitle = `${currentTime}-${fileName}`;

    const metadata = {
         contentType: file.type
    };

    const task = storage.ref().child(fileTitle).put(file, metadata);


    task.then(snapshot => snapshot.ref.getDownloadURL())
        .then(console.log)
        .catch(console.error);

};

export default router;

错误

无法导入 Node.js 的 Cloud Storage 客户端库。确保安装“@google-cloud/storage”npm 包。原始错误：Error: EIO: i/o error, read

虽然我已经在我的包列表中安装了@google-cloud/storage

1. 将storageBucket 添加到您的admin.initializeApp({})

if (!admin.apps.length) {
  try {
    admin.initializeApp({
      credential: admin.credential.cert(serviceAccount),
      databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL,
      storageBucket: process.env.NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET,
    });
  } catch (e) {
    console.log("Failed to initialize App: " + e);
  }
}

1. 使用admin.storage().bucket() 而不是admin.storage()

import * as admin from "firebase-admin";
import serviceAccount from "./firebase.serviceAccount.json";

if (!admin.apps.length) {
    admin.initializeApp({
        credential: admin.credential.cert(serviceAccount),
        databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL
    });
}

const firestore = admin.firestore();
const storage = admin.storage().bucket();

export { firestore, storage };
