Clash 线路查看工具

查看本机当前活跃连接，确认指定进程命中的规则、策略组与真实出口。不接受 SSH 参数；远程机器应先通过 Tailscale SSH 登录，再在目标机器执行同一只读流程。

用户传入的参数：$ARGUMENTS。没有参数时列出所有活跃连接。诊断 Gemini、ChatGPT 或浏览器流量时，先不加过滤获取实际 metadata.process，再使用观察到的进程名；不要假定它们属于 claude。

获取凭证

读取 Clash Verge 配置，但不要打印 secret：

SECRET=$(grep '^secret:' "$HOME/Library/Application Support/io.github.clash-verge-rev.clash-verge-rev/clash-verge.yaml" 2>/dev/null | awk '{print $2}')
[ -z "$SECRET" ] && SECRET=$(grep '^secret:' "$HOME/.config/clash/config.yaml" 2>/dev/null | awk '{print $2}')
[ -n "$SECRET" ] && echo "API secret: configured" || echo "API secret: not configured"

查询与回退

请求成功才采用该 endpoint。/tmp socket 存在但失效时继续尝试 /var/tmp，最后尝试配置的 HTTP controller。所有 endpoint 都失败时明确报错，不返回空数据。

request_connections() {
  for socket_path in \
    /tmp/verge/verge-mihomo.sock \
    /var/tmp/verge/verge-mihomo.sock
  do
    [ -S "$socket_path" ] || continue
    if curl --fail --silent --show-error \
      --unix-socket "$socket_path" \
      "http://localhost/connections" \
      -H "Authorization: Bearer $SECRET"
    then
      return 0
    fi
  done

  controller=$(grep '^external-controller:' "$HOME/Library/Application Support/io.github.clash-verge-rev.clash-verge-rev/clash-verge.yaml" 2>/dev/null | awk '{print $2}' | tr -d "'\"")
  [ -n "$controller" ] || controller="127.0.0.1:9090"
  curl --fail --silent --show-error \
    "http://$controller/connections" \
    -H "Authorization: Bearer $SECRET"
}

if ! DATA=$(request_connections); then
  echo "无法从 Mihomo Unix socket 或 HTTP controller 获取连接数据" >&2
  exit 1
fi

if ! printf '%s' "$DATA" | python3 -c 'import json, sys; value=json.load(sys.stdin); assert isinstance(value.get("connections"), list)' 2>/dev/null; then
  echo "Mihomo 返回了无效的 connections JSON" >&2
  exit 1
fi

解析并展示

通过环境变量传递过滤值，避免把用户输入插进 Python 源码：

printf '%s' "$DATA" | FILTER="$ARGUMENTS" python3 -c '
import json
import os
import sys
from collections import defaultdict

        continue
    host = metadata.get("host", "") or metadata.get("destinationIP", "")
    port = metadata.get("destinationPort", "")
    rule = connection.get("rule", "")
    payload = connection.get("rulePayload", "")
    if payload:
        rule += "/" + payload
    chains = connection.get("chains", [])
    chain_text = " → ".join(reversed(chains)) if chains else "DIRECT"
    results.append({

    target = process_filter or "任何进程"
    print(f"未找到 {target} 的活跃连接")
    raise SystemExit(0)
