2. 方案一：Cloudflare Workers 5 分钟极速部署代码
</h2>
<p class="text-slate-600 dark:text-slate-300 leading-relaxed text-sm sm:text-base">
登录 Cloudflare Dashboard，创建新的 Worker 并粘贴以下经过生产加固的处理代码。本代码严格内置了<strong>域名白名单过滤</strong>，杜绝被黑产当做开放代理滥用：

3. 方案二：独立 VPS OpenResty / Nginx 生产级配置（极致性能）
</h2>
<p class="text-slate-600 dark:text-slate-300 leading-relaxed text-sm sm:text-base">
若需支撑企业百人研发团队或大型 CI/CD 节点并发构建，推荐在海外 VPS（配置 2C4G 以上）上部署 OpenResty。以下为经过高并发实战调优的 Nginx 配置文件：

4. 自建节点安全防护军规：严防公网盗用
</h2>
<div class="p-4 rounded-xl border border-red-200 dark:border-red-900/50 bg-red-50/40 dark:bg-red-950/20 text-xs sm:text-sm space-y-2">
<div class="font-bold text-red-700 dark:text-red-400">为什么自建代理极易被封停？</div>
<p class="text-slate-700 dark:text-slate-300">
很多开发者搭建好代理后未加限制，扫描器在几小时内就能发现该开放中继，随后将其作为垃圾邮件发送、暗网数据爬取或盗取外网资源的跳板。一旦云厂商检测到异常大流量违规外联，将直接下发警告甚至<strong>封停整个 VPS 账户</strong>。
</p>
<div class="font-bold text-red-700 dark:text-red-400 mt-2">防范策略：</div>
<ul class="list-disc list-inside space-y-1 text-slate-700 dark:text-slate-300">
<li><strong>严格限制上游目标域名</strong>：仅放行 GitHub 官方域名族（如上文 Nginx 配置所示）；</li>
<li><strong>开启 Nginx 速率限制</strong>：使用 <code>limit_req_zone</code> 限制单 IP 每秒请求频次；</li>
<li><strong>企业私有部署注入 Header 令牌</strong>：在 Nginx 配置中校验特定 <code>X-Proxy-Token</code> 自定义头，非内部员工拒绝中继。</li>
</ul>
