React本机将图像转换为byteAraay，反之亦然

import React, { useState } from 'react';

const ImageToByteArrayConverter = () => {
  const [byteArray, setByteArray] = useState(null);

  const handleImageUpload = (event) => {
    const file = event.target.files[0];
    const reader = new FileReader();

    reader.onload = (e) => {
      const arrayBuffer = e.target.result;
      const byteArray = new Uint8Array(arrayBuffer);
      setByteArray(byteArray);
    };

    reader.readAsArrayBuffer(file);
  };

  return (
    <div>
      <input type="file" onChange={handleImageUpload} />
      {byteArray && (
        <div>
          <p>Converted ByteArray:</p>
          <pre>{JSON.stringify(byteArray)}</pre>
        </div>
      )}
    </div>
  );
};

export default ImageToByteArrayConverter;
