Thought for 1m 46s

Resposta

你这个报错本质是跨域(CORS) + 预检(OPTIONS) 请求 404，再叠加了几个配置问题：

  • 页面在 http://192.168.11.1（80 端口），WebDAV 在 http://192.168.11.1:8081（不同端口 ⇒ 不同源）
  • lighttpd 没返回 Access-Control-Allow-* 头；
  • 预检 OPTIONS 命中 404（WebDAV/路径/鉴权没有正确处理）；
  • 你现在的 WebDAV 还是只读（webdav.is-readonly = "enable"），即使过了 CORS，PUT/DELETE 也会失败。

下面给出两种可选的解决方案，任选其一即可。

方案 A（推荐，最省心）：改成“同源”，彻底避免 CORS

把 clipboard.html 从 8081 提供，并让前端请求同一端口的 WebDAV。

  1. 把页面放到 lighttpd 的根目录（你现在是 /root）：
sh
mv /www/clipboard.html /root/clipboard.html
  1. 修改前端常量（避免跨域）：
js
// 把 webdavUrl 改成相对路径（不含协议和端口）
const webdavUrl = '/rax3000m_emmc/clipboard/images/';

之后用 http://192.168.11.1:8081/clipboard.html 打开页面即可。

注意：你的 textApi = '/cgi-bin/clipboard.sh' 仍然走 80 端口的 uhttpd（LuCI），会再次跨域。

  • 最简单：把 textApi 也写成绝对地址 http://192.168.11.1:8081/cgi-bin/clipboard.sh，并在 lighttpd 做反代（见下方“可选：反向代理”）；
  • 或者把 CGI 脚本迁到 lighttpd（需要启用 cgi/fcgi，不展开）。

可选：在 lighttpd 给 /cgi-bin/ 做反向代理到 80 端口（这样依然同源 8081）：

text
# /etc/lighttpd/conf.d/35-proxy.conf
server.modules += ( "mod_proxy" )
proxy.server = ( "/cgi-bin/" => ( ( "host" => "127.0.0.1", "port" => 80 ) ) )

然后把前端里的 textApi 改为：

js
const textApi = '/cgi-bin/clipboard.sh';

方案 B：保留跨端口，正确开启 CORS（含预检 & 写权限）

1) 让目录真实存在并可写

sh
mkdir -p /root/rax3000m_emmc/clipboard/images
chown -R http:www-data /root/rax3000m_emmc
chmod -R 775 /root/rax3000m_emmc

2) 正确限定 WebDAV 路径、允许写、并返回 CORS 头

把 /etc/lighttpd/conf.d/30-webdav.conf 改成按路径生效，并加上 CORS。示例（可直接覆盖成下面这段）：

text
#######################################################################
## WebDAV on /rax3000m_emmc/clipboard/images
#######################################################################
server.modules += ( "mod_webdav", "mod_setenv" )

$HTTP["url"] =~ "^/rax3000m_emmc/clipboard/images($|/)" {
  webdav.activate = "enable"
  webdav.is-readonly = "disable"   # 允许 PUT/DELETE
  webdav.sqlite-db-name = "/root/rax3000m_emmc/webdav.db"

  # CORS 响应头（按需要精确到你的来源）
  setenv.add-response-header = (
    "Access-Control-Allow-Origin" => "http://192.168.11.1",
    "Access-Control-Allow-Credentials" => "true",
    "Access-Control-Allow-Methods" => "GET, PUT, DELETE, PROPFIND, MKCOL, OPTIONS",
    "Access-Control-Allow-Headers" => "Authorization, Depth, Content-Type, Destination, Overwrite",
    "Access-Control-Max-Age" => "86400"
  )

  # 预检请求不做鉴权拦截，直接 200
  $HTTP["request-method"] == "OPTIONS" {
    auth.require = ()
  }
}

说明：

  • mod_setenv 用于添加响应头；
  • OPTIONS 子块清空了 auth.require，否则浏览器的预检不会带凭据，会被 401/403 拦住；
  • webdav.is-readonly = "disable" 才能上传/删除。

3) 把全局鉴权改成“只保护需要的路径”

你当前 /etc/lighttpd/conf.d/20-auth.conf 把 全站 "/" 都做了 Basic 认证，会影响预检。改成只在 WebDAV 路径上鉴权（或保持你需要的其它路径），并与上面的 OPTIONS 豁免配合：

text
server.modules += ( "mod_auth", "mod_authn_file" )
auth.backend                 = "plain"
auth.backend.plain.userfile  = "/etc/lighttpd/lighttpd.user"

# 仅保护 WebDAV 目录（如需）
$HTTP["url"] =~ "^/rax3000m_emmc/clipboard/images($|/)" {
  auth.require = ( "" =>
    ( "method"  => "basic",
      "realm"   => "WebDAV",
      "require" => "valid-user"
    )
  )
}

如果你还要保护别的目录，可按需再加对应的 $HTTP["url"] 块。不要再用对 "/" 的全局保护，否则还得额外豁免预检。

4) 重启并自检

sh
/etc/init.d/lighttpd restart

自检（在路由器上执行）：

sh
# 预检（应返回 200 且含 Access-Control-Allow-*）
curl -i -X OPTIONS \
  'http://192.168.11.1:8081/rax3000m_emmc/clipboard/images/' \
  -H 'Origin: http://192.168.11.1' \
  -H 'Access-Control-Request-Method: PROPFIND' \
  -H 'Access-Control-Request-Headers: authorization, depth'

# 列目录（PROPFIND）
curl -i -X PROPFIND \
  'http://192.168.11.1:8081/rax3000m_emmc/clipboard/images/' \
  -u asdf:asdf -H 'Depth: 1'

# 上传（PUT）
curl -i -X PUT --data-binary @/etc/banner \
  'http://192.168.11.1:8081/rax3000m_emmc/clipboard/images/test.txt' \
  -u asdf:asdf

前端不改也能跑的小调整

你的 JS 已经手动加了 Authorization: Basic ...，这是可以的；只要服务器允许跨域并放行预检就行。
另外建议把允许的方法里包含 MKCOL（有些 WebDAV 客户端会用到）。

额外提示

  • 账号 asdf/asdf 太弱了，至少换个强密码；
  • 若开启了 Access-Control-Allow-Credentials: true，Origin 不能用 *，要写成具体来源（上面已示范）；
  • favicon.ico 的 404 无关紧要，想消除就放一个到 /root/favicon.ico 或在 HTML 里 <link rel="icon" href="data:,">；
  • 如果仍返回 404，十有八九是目录不存在/路径不匹配或 WebDAV 没在该 URL 上激活，按上面的“路径正则 + 目录存在”检查即可。

一句话总结

要么把页面和 WebDAV 放到同一个端口（最简单），要么在 8081 上正确开启 CORS + 放行 OPTIONS + 允许写。上面的配置按步骤套上去即可解决你看到的 No 'Access-Control-Allow-Origin' 和预检 404。
