如何将base64映像上传到firebase存储？

var base64Image = "YOUR_BASE64_IMAGE";
var byteString = atob(base64Image.split(",")[1]);
var mimeType = base64Image.split(",")[0].split(":")[1].split(";")[0];
var arrayBuffer = new ArrayBuffer(byteString.length);
var uintArray = new Uint8Array(arrayBuffer);

for (var i = 0; i < byteString.length; i++) {
  uintArray[i] = byteString.charCodeAt(i);
}

var blobImage = new Blob([arrayBuffer], { type: mimeType });

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

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

// 上传Blob对象到Firebase存储
var uploadTask = storageRef.child("images/image.jpg").put(blobImage);

uploadTask
  .then(function(snapshot) {
    // 上传成功后的处理逻辑
    console.log("Image uploaded successfully");
    // 获取已上传图片的下载URL
    snapshot.ref.getDownloadURL().then(function(downloadURL) {
      console.log("Download URL:", downloadURL);
    });
  })
  .catch(function(error) {
    // 上传失败后的处理逻辑
    console.error("Error uploading image:", error);
  });
