如何理解结果Understand the result
点击后才读取。结果来自独立同源请求，不携带 Cookie，也不回显凭据。Read only after you press the button. This inspects a separate same-origin request, without cookies or credentials.
原理、限制与隐私说明How it works, limitations & privacy
点击读取后，同源请求 /api/request-environment，且不携带 Cookie。结果描述此次 fetch，而非最初页面导航；各变量附带来源与解释。Pressing Read fetches /api/request-environment from the same site, with cookies omitted. It describes that fetch—not the original page navigation. Request variables have provenance and explanations.
不返回 Cookie、Authorization、签名、任意请求头、查询字符串、凭据、证书或服务器绑定。转发 IP 字段只有包含合法 IP 列表时才返回。Cookies, authorization, signatures, arbitrary headers, query strings, credentials, certificates and server bindings are excluded. Forwarded-IP fields are returned only if they contain valid IP addresses.
此平台不暴露 REMOTE_PORT；客户端提示可能缺失。边缘国家 / ASN 仅为托管平台报告，不代表精确位置、独立核验的归属或匿名性结论。不新增应用日志 / 存储；托管平台可能保留访问日志。REMOTE_PORT is not exposed by this platform. Client hints may be missing. Edge country/ASN fields are only hosting-provider reports, not precise location, independently verified ownership or an anonymity verdict. No application logs/storage are added; hosting-provider access logs may exist.
