如何在数组中推送base64格式的文件？

// 将base64格式的文件转换为Blob对象
function base64ToBlob(base64) {
  const binaryString = atob(base64);
  const bytes = new Uint8Array(binaryString.length);
  for (let i = 0; i < binaryString.length; i++) {
    bytes[i] = binaryString.charCodeAt(i);
  }
  return new Blob([bytes]);
}

// 将Blob对象转换为File对象
function blobToFile(blob, filename) {
  return new File([blob], filename);
}

// 示例使用
const base64String = "base64格式的文件字符串";
const filename = "example.txt";

const blob = base64ToBlob(base64String);
const file = blobToFile(blob, filename);

const fileArray = [];
fileArray.push(file);
