test: VPN 黑盒测试工具改用 Python(零依赖)+ HTML 报告 + 国内外站点矩阵
- scripts/vpn_test.py:替换 vpn_test.sh。纯标准库(socket/ssl/urllib),覆盖国内外 常见站点矩阵(google/youtube/github/x/fb/ig/wiki/cloudflare/openai/reddit; 百度/腾讯/淘宝/京东/B站/微博/网易/知乎/阿里云),测连通+延迟+TTFB+DNS+出口IP+吞吐, 本机连通性(tun/系统扩展),生成自包含 HTML 报告(-o)。 - 延迟标准 = TLS 握手耗时(ssl 握手,纯链路往返),报告里标注 "TTL=按 TLS 计算、非 IP TTL"; TTFB 作参考。禁用 ping/tcp_connect(经 TUN 本地应答失真)。 - 删除 scripts/vpn_test.sh;文档引用同步更新为 .py。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JEHzjEcFzvGwgbxT6Wbt6c
