<h1>🌐 Edge Proxy Middleware</h1>
<p>基于 Deno Deploy 的边缘代理服务，支持任意网站代理。</p>
<h2>使用方法</h2>
<p>在要代理的域名前加上此服务的地址：</p>
<div class="example">
<strong>格式1：</strong> <code>${url.origin}/github.com</code><br>
<strong>格式2：</strong> <code>${url.origin}/https://github.com</code><br>
<strong>格式3：</strong> <code>${url.origin}/api/edge?url=https://github.com</code><br>
<strong>格式4：</strong> <code>${url.origin}/api/edge?r=aHR0cHM6Ly9naXRodWIuY29t</code> (base64编码)
</div>
<h2>快速测试</h2>
<div class="example">
<p>点击以下链接测试代理功能：</p>
<p><a href="/httpbin.org/get" target="_blank">🔗 测试 httpbin.org</a></p>
<p><a href="/api/edge?url=https://httpbin.org/ip" target="_blank">🔗 获取IP信息</a></p>
<p><a href="/github.com" target="_blank">🔗 代理 GitHub</a></p>
</div>
<p>访问后会自动识别代理主机名并写入 Cookie，之后路径将完全对应。</p>
<p><small>💡 提示：Cookie 24小时后过期，届时请重新访问主机名。</small></p>
