如何在react/js中读取和下载二进制文件

function downloadBinaryFile(url, filename) {
  fetch(url)
    .then(response => response.arrayBuffer())
    .then(data => {
      const blob = new Blob([data]);
      const url = URL.createObjectURL(blob);
      const link = document.createElement('a');
      link.href = url;
      link.download = filename;
      const event = document.createEvent('MouseEvents');
      event.initEvent('click', true, false);
      link.dispatchEvent(event);
    })
    .catch(error => {
      console.error('Error downloading binary file:', error);
    });
}

// 使用示例
downloadBinaryFile('https://example.com/file.bin', 'file.bin');
