# Quantumult X 资源解析器 (2020-05-22: 19:59 )

本资源解析器作者: Shawn(请勿私聊问怎么用)，有bug请反馈: @Shawn_KOP_bot
更新请关注tg频道: https://t.me/QuanX_API

主要功能: 将各类服务器订阅解析成 QuantumultX 格式引用(支持 V2RayN/SSR/SS/Trojan/QuanX(conf&list)/Surge(conf&list)格式)，并提供 1⃣️ 中的可选参数；

附加功能: rewrite(重写) /filter(分流) 过滤, 可用于解决无法单独禁用远程引用中某(几)条 rewrite/hostname/filter, 以及直接导入 Surge 类型规则 list 的问题

0️⃣ 请在“订阅链接”后加入 "#" 后再加参数, 不同参数间请使用 "&" 来连接, 如: 
"https://mysub.com#in=香港+台湾&emoji=1&tfo=1"

1️⃣ "节点" 订阅--参数说明:
- in, out, 分别为 保留/排除, 多参数用 "+" 连接(逻辑"或"), 逻辑"与"请用"."连接，可直接用中文, 空格用"%20"代替 (如 "in=香港.IPLC.04+台湾&out=香港%20BGP" );
- emoji=1,2 或 -1, 为添加/删除节点名中的 emoji 旗帜 (国行设备请用 emoji=2 );
- udp=1, tfo=1 参数开启 udp-relay 及 fast-open (默认关闭, 此参数对源类型为 QuanX/Surge 的链接无效);
- rename 重命名, rename=旧名@新名, 以及 "前缀@", "@后缀", 用 "+" 连接, 如 "rename=香港@HK+[SS]@+@[1X]";
- cert=0，跳过证书验证(vmess/trojan)，即强制"tls-verification=false";
- tls13=1, 开启 "tls13=true"(vmess/trojan), 请自行确认服务端是否支持;
- sort=1 或 sort=-1, 排序参数，分别根据节点名 正序/逆序 排列;
- info=1, 开启通知提示流量信息(前提：原订阅链接有返回该信息)，默认关闭

2⃣️ "rewrite(重写)/filter(分流)" 引用--参数说明:
- 参数为 "out=xxx", 多个参数用 "+" 连接;
- 分流规则额外支持 "policy=xx" 参数, 可用于直接指定策略组，或者为 Surge 格式的 rule-set 生成策略组(默认"Shawn"策略组)
⚠️⚠️ 由于 rewrite/filter 的 UI 中暂时没有提供解析器开关，想使用的请自行去配置文件中的相关行，添加参数"opt-parser=true"以开启，如：
https://Advertising.list#policy=MineGroup&out=aweme, tag=🚦去广告，update-interval=86400, opt-parser=true, enabled=true

3⃣️ 通用参数: ntf=1, 用于打开资源解析器的提示通知 (默认关闭), 
- rewrite/filter 类型则会强制在有 out 参数时开启通知提示被删除（禁用）的内容，以防止规则误删除

 */


/**
 * 使用说明，
0️⃣ 在QuantumultX 配置文件中[general] 部分，加入 resource_parser_url=https://raw.githubusercontent.com/KOP-XIAO/QuantumultX/master/Scripts/resource-parser.js
⚠️⚠️如提示"没有自定义解析器"，请长按右下角图标后点击左侧刷新按钮，更新资源，后台退出 app，直到出现解析器说明
1️⃣ 假设原始订阅连接为: https://raw.githubusercontent.com/crossutility/Quantumult-X/master/server-complete.txt , 
2️⃣ 假设你想要保留的参数为 in=tls+ss, 想要过滤的参数为 out=http+2, 请注意下面订阅链接后一定要加 ”#“ 符号
3️⃣ 则填入 Quanx 节点引用的的总链接为  https://raw.githubusercontent.com/crossutility/Quantumult-X/master/server-complete.txt#in=tls+ss&out=http+2
4️⃣ 填入上述链接, 并打开的资源解析器开关
------------------------------
⚠️⚠️ 由于 rewrite/filter 的 UI 中暂时没有提供解析器开关，想使用的请自行去配置文件中的相关行，添加参数"opt-parser=true"以开启，如：
https://Advertising.list#policy=Shawn&out=aweme, tag=🚦去广告，update-interval=86400, opt-parser=true, enabled=true
