只显示根目录的文件，不显示文件夹及文件夹里的文件

但是可以通过网址后面加上路径，访问文件夹里面的文件的内容，但是不能通过这种方式访问文件夹

Modify workflow's two methods:
listAll:

async function* listAll(bucket, prefix) {
  const options = { prefix, delimiter: "/" };
  let result = await bucket.list(options);

  if (result.delimitedPrefixes) {
    for (const prefix of result.delimitedPrefixes) {
      yield {
        key: prefix,
        size: 0,
        uploaded: new Date(),
        httpMetadata: {},
        customMetadata: { resourcetype: "collection" },
        etag: ""
      };
    }
  }

  while (result.objects.length > 0) {
    for (const object of result.objects) {
      yield object;
    }
    if (result.truncated && result.cursor) {
      result = await bucket.list({ ...options, cursor: result.cursor });
    } else {
      break;
    }
  }
}

second: handleDirectory

async function handleDirectory(bucket, resource_path, bucketName) {
  logger.info("Current directory path:", resource_path);
  
  let items = [];
  if (resource_path !== "") {
    items.push({ name: "📁 ..", href: "../" });
  }

  try {
    for await (const object of listAll(bucket, resource_path)) {
      if (object.key === resource_path) continue;

      const isDirectory = object.customMetadata?.resourcetype === "collection";
      const displayName = object.key.replace(resource_path, "").split("/")[0];
      
      const href = isDirectory 
        ? object.key.endsWith('/') ? `/${object.key}` : `/${object.key}/`
        : `/${object.key}`;

      items.push({ 
        name: `${isDirectory ? "📁 " : "📄 "}${displayName}`, 
        href: href.replace(/\/+/g, '/')
      });
    }
  } catch (error) {
    const err = error;
    logger.error("Error listing objects:", err.message);
    return new Response(generateErrorHTML("Error listing directory contents", err.message), {
      status: 500,
      headers: { "Content-Type": "text/html; charset=utf-8" }
    });
  }

  const page = generateHTML("WebDAV File Browser", items);
  return new Response(page, {
    status: 200,
    headers: { "Content-Type": "text/html; charset=utf-8" }
  });
}
