如何获取本地图像路径，将其转换为File对象，然后将其上传到firebase？

<input type="file" id="fileInput">
<button onclick="uploadImage()">Upload</button>

function uploadImage() {
  const fileInput = document.getElementById("fileInput");
  const file = fileInput.files[0];
  
  // 将文件传递给下一步操作函数
  uploadToFirebase(file);
}

npm install firebase

const firebase = require("firebase");
require("firebase/storage");

// 配置Firebase
const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  // ...
};

// 初始化Firebase
firebase.initializeApp(firebaseConfig);

// 获取Firebase存储引用
const storageRef = firebase.storage().ref();

async function uploadToFirebase(file) {
  try {
    // 在Firebase中创建一个唯一的文件名
    const fileName = `${Date.now()}-${file.name}`;

    // 将文件上传到Firebase存储桶
    const snapshot = await storageRef.child(fileName).put(file);

    console.log("上传成功");
    console.log("文件访问URL:", snapshot.ref.getDownloadURL());
  } catch (error) {
    console.error("上传失败", error);
  }
}
