#请求头 | 折腾啥

Sub-Store 小课堂: 根据请求头内容自动过滤协议

例如根据 Surge 客户端实际解锁了哪些来进行筛选

可让 AI 帮忙修改我人废了

function operator(proxies, target, context) {
  if ($options?._req) {
    const { headers, url, path } = $options?._req || {};
    // 获取 user-agent
    const ua = headers?.["user-agent"] || headers?.["User-Agent"];
    console.log(`User-Agent: ${ua}`);
    let types = [];
    if (target === "Surge") {
      const isSurgeiOS = ua?.startsWith("Surge iOS/");
      if (isSurgeiOS) {
        // 获取 Surge 已解锁的功能
        const features = (
          headers?.["x-surge-unlocked-features"] ||
          headers?.["X-Surge-Unlocked-Features"]
        )?.split(/\s*,\s*/);
        console.log(`Surge 已解锁的功能: ${features}`);

        // 如果能取到 Surge 已解锁的功能 并且 里面没有 anytls, 就过滤掉 anytls
        if (features && !features.includes("anytls")) {
          types.push("anytls");
        }
      } else if (
        ua?.startsWith("Surge Mac/") &&
        ua?.match(/\/(\d+)/)?.[1] < 9860
      ) {
        // 若 Surge Mac 版本小于 9860，就过滤掉 anytls
        types.push("anytls");
      }
    } else if (target === "Egern") {
      const build = ua?.match(/Build\/(\d+)/)?.[1];
      console.log(`Egern Build: ${build}`);
      // 更旧的版本里 user-agent 里没 build
      // 判断旧版 就过滤掉 anytls
      if (ua?.startsWith("egern/") && (!build || build < 718)) {
        types.push("anytls");
      }
    }
    return proxies.filter((proxy) => !types.includes(proxy.type));
  }
  return proxies;
}
