在 Firebase Web 客户端中,将文件压缩为 GZIP 格式并上传到 Firebase Cloud Storage 是一个常见的需求。以下是一个完整的示例,展示如何在 Firebase Web 客户端中实现这一功能。
npm install firebase
// firebaseConfig.js
import { initializeApp } from 'firebase/app';
import { getStorage } from 'firebase/storage';
const firebaseConfig = {
apiKey: "YOUR_API_KEY",
authDomain: "YOUR_AUTH_DOMAIN",
projectId: "YOUR_PROJECT_ID",
storageBucket: "YOUR_STORAGE_BUCKET",
messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
appId: "YOUR_APP_ID"
};
const app = initializeApp(firebaseConfig);
const storage = getStorage(app);
export { storage };
zlib
库来压缩文件,然后将其上传到 Firebase Cloud Storage。// upload.js
import { ref, uploadBytes } from 'firebase/storage';
import { storage } from './firebaseConfig';
import { gzip } from 'pako'; // 使用 pako 库进行 GZIP 压缩
// 选择文件
const fileInput = document.getElementById('fileInput');
fileInput.addEventListener('change', async (event) => {
const file = event.target.files[0];
if (file) {
try {
// 读取文件内容
const fileContent = await file.arrayBuffer();
// 压缩文件内容
const compressedContent = gzip(new Uint8Array(fileContent));
// 创建 Firebase Storage 引用
const storageRef = ref(storage, `compressed/${file.name}.gz`);
// 上传压缩文件
const snapshot = await uploadBytes(storageRef, compressedContent, {
contentType: 'application/gzip'
});
console.log('Uploaded a blob or file!', snapshot);
} catch (error) {
console.error('Error uploading file:', error);
}
}
});
