下载作为字节数组传递的React js上的文件

import React from "react";

const downloadByteArrayFile = (byteArray, fileName) => {
  const blob = new Blob([byteArray]);
  const url = URL.createObjectURL(blob);

  const a = document.createElement("a");
  a.href = url;
  a.download = fileName;
  a.style.display = "none";
  document.body.appendChild(a);
  a.click();
  document.body.removeChild(a);
  URL.revokeObjectURL(url);
};

const App = () => {
  const handleDownload = () => {
    // 假设字节数组和文件名已经准备好
    const byteArray = [/* 字节数组数据 */];
    const fileName = "example.txt";

    downloadByteArrayFile(byteArray, fileName);
  };

  return (
    <div>
      <button onClick={handleDownload}>下载文件</button>
    </div>
  );
};

export default App;
