onedrive直链加速方案

⚠️ 注意：本项目仅适合短时间、小流量下载文件。长期、大流量使用可能被 Cloudflare 判定为滥用，或被要求升级 Pro 版本。

1. 获取 OneDrive 域名

1. 在 OneDrive 中任选 1 个文件 → 点击「分享」→「复制链接」
2. 得到类似链接：<code>https://test-my.sharepoint.com/:i:/g/personal/xxx/yyy?e=zzz</code>
3. 仅复制域名（不含协议）：<code>test-my.sharepoint.com</code>

2. 部署 Cloudflare Worker

1. 登录 Cloudflare Dashboard → Workers →「创建服务」
2. 删除默认代码，粘贴下方内容，并将 <code>test-my.sharepoint.com</code> 替换成你刚才复制的域名：

// =====  只需改这里 =====
const upstream        = 'test-my.sharepoint.com'   // 你的域名
const upstream_mobile = 'test-my.sharepoint.com'   // 同上
// =======================

const upstream_path        = '/'
const blocked_region       = ['KP', 'SY', 'PK', 'CU']
const blocked_ip_address   = ['0.0.0.0', '127.0.0.1']
const https                = true
const disable_cache        = false
const replace_dict         = {
  '$upstream'     : '$custom_domain',
  '//sunpma.com'  : ''
}
const not_found_html_content = <code>404</code>

addEventListener('fetch', event => {
  event.respondWith(fetchAndApply(event.request))
})

async function fetchAndApply(req) {
  const region     = req.headers.get('cf-ipcountry')?.toUpperCase()
  const ip         = req.headers.get('cf-connecting-ip')
  const ua         = req.headers.get('user-agent')
  const url        = new URL(req.url)
  const urlHost    = url.hostname

  // ---------- 路径过滤 ----------
  if (url.pathname === '/personal' || !url.pathname.includes('/personal/')) {
    return new Response(not_found_html_content, {
      status : 404,
      headers: { 'Content-Type': 'text/html; charset=UTF-8' }
    })
  }

  }

    return new Response('Access denied: Your IP address is blocked by WorkersProxy.', { status: 403 })
  }

  const newHdr = new Headers(req.headers)
  newHdr.set('Host', url.host)

  resHdr.set('access-control-allow-origin', '*')
  resHdr.set('access-control-allow-credentials', 'true')
  resHdr.delete('content-security-policy')
  resHdr.delete('content-security-policy-report-only')
  resHdr.delete('clear-site-data')

  if (resHdr.get('x-pjax-url')) {
    resHdr.set('x-pjax-url',
      resHdr.get('x-pjax-url').replace(<code>//${upstream}</code>, <code>//${urlHost}</code>))
  }

  let body = res.body
  if (contentTp.includes('text/html') && contentTp.includes('UTF-8')) {
    body = await replace_response_text(await res.text(), upstream, urlHost)
  }

  return new Response(body, { status: res.status, headers: resHdr })
}

async function replace_response_text(text, up, host) {
  for (const [k, v] of Object.entries(replace_dict)) {
    const key = k === '$upstream' ? up : (k === '$custom_domain' ? host : k)
    const val = v === '$upstream' ? up : (v === '$custom_domain' ? host : v)
    text = text.replace(new RegExp(key, 'g'), val)
  }
  return text
}

async function device_status(ua) {
  const mobile = ['Android', 'iPhone', 'SymbianOS', 'Windows Phone', 'iPad', 'iPod']
  return !mobile.some(m => ua.includes(m))
}

💡

至此，Cloudflare Workers 反代节点已搭建完成。轻量场景下可显著改善 OneDrive 直链速度；若出现 100 GB 级持续高流量，请及时分流或升级至 Cloudflare Pro，避免被平台限流。祝使用愉快！
