Important

Clash <-> Sharelink 转换功能已拆分为单独的仓库: siiway/urlclash-converter

路由

• / -> 根目录 (根据访问客户端自动选择 HTML / 纯文本)
• /json -> 返回 JSON 格式的数据
• /txt -> 返回纯文本格式的数据
• /html -> 返回网页格式的数据
• /ip -> 只返回访问者 IP，不带任何格式 / 说明
• /full -> 以 JSON 格式返回脚本获取到的所有信息 (IP, 归属地, Headers, Security, ...)

自行部署

请确保设置片段规则为 自定义筛选表达式

• 字段: 主机名
• 运算符: 等于
• 值: 你想要的域名

切勿选择 所有传入请求, 否则会导致你整个域名的流量被路由到 snippet!

Example:

Tip

如果出现提示 此规则可能不适用于您的流量, 只需要随指引创建一个对应的代理 A 记录，目标填写 192.0.2.1 即可
