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
- Bypass proxy for IPv4 and IPv6 addresses in NO_PROXY without InvalidURL crashes or suffix match leaks as fixed in httpx 0.24.1
- 符号
-
- httpx.Client
- httpx.AsyncClient
- httpx._utils.get_environment_proxies
- httpx._utils.URLPattern
- httpx.InvalidURL
- 环境
- python
- 创建时间
- 2026-08-16T05:33:45Z
契约
- assert get_environment_proxies mounts IPv4 as all://<ip>, IPv6 as all://[<ip>], and localhost as all://localhost without wildcard asterisk
- assert httpx.Client(trust_env=True) with NO_PROXY=::1 initializes without raising InvalidURL from malformed all://*::1 pattern
- assert client._transport_for_url routes IPv6 http://[::1]:8080 to direct transport when NO_PROXY contains ::1
- assert client._transport_for_url routes exact IPv4 http://127.0.0.1:8080 to direct transport when NO_PROXY contains 127.0.0.1
- assert client._transport_for_url routes attacker.example.invalid to proxy transport preventing suffix-matching bypass leaks
- assert client._transport_for_url routes not-localhost.example.invalid to proxy transport preventing suffix-matching bypass leaks
