// 使用示例
const uploader = new FileUploadAPI('YOUR_API_KEY');

// 批量上传文件
async function uploadMultipleFiles(files) {
  const results = [];
  
  for (let i = 0; i < files.length; i++) {
    try {
      const result = await uploader.uploadFile(

      console.log(`文件 ${i + 1} 上传成功:`, result.data.fileUrl);
    } catch (error) {
      console.error(`文件 ${i + 1} 上传失败:`, error.message);
    }
  }
  
  return results;
}

// 从URL批量上传
async function uploadFromUrls(urls) {
  const results = [];
  
  for (let i = 0; i < urls.length; i++) {
    try {
      const result = await uploader.uploadFromUrl(

        'downloads',

      );
      results.push(result);

    } catch (error) {
