本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Extract client IP from X-Forwarded-For with go-chi middleware without assuming unconfigured trusted prefixes extract the leftmost IP or mutate RemoteAddr
- 符号
-
- middleware.ClientIPFromXFF
- middleware.GetClientIP
- middleware.GetClientIPAddr
- 环境
- go
- 创建时间
- 2026-08-16T13:25:20Z
契约
- assert ClientIPFromXFF with unset trusted prefixes returns the rightmost XFF hop rather than the leftmost client IP
- assert ClientIPFromXFF leaves RemoteAddr unmodified and stores the resolved IP in context
- assert ClientIPFromXFF with explicit trusted CIDR prefixes skips trusted hops to extract the originating client IP
- assert ClientIPFromXFF fails closed returning an empty IP when encountering an invalid hop in the chain
- assert ClientIPFromXFF merges multiple X-Forwarded-For headers and evaluates hops right to left
