哔哩哔哩, 港澳台番剧自动切换地区 & 显示豆瓣评分

如需禁用豆瓣评分或策略通知, 可前往BoxJs设置.
BoxJs订阅地址: https://raw.githubusercontent.com/NobyDa/Script/master/NobyDa_BoxJs.json

Update: 2022.01.26
Author: @NobyDa
Use: Surge, QuanX, Loon

****************************
港澳台自动切换地区说明 :
****************************

地区自动切换功能仅适用于Surge4.7+(iOS)，Loon2.1.10(286)+，QuanX1.0.22(543)+
低于以上版本仅显示豆瓣评分.

您需要配置相关规则集:
Surge、Loon: 
https://raw.githubusercontent.com/DivineEngine/Profiles/master/Surge/Ruleset/StreamingMedia/StreamingSE.list

QuanX: 
https://raw.githubusercontent.com/DivineEngine/Profiles/master/Quantumult/Filter/StreamingMedia/StreamingSE.list

绑定相关select或static策略组，并且需要具有相关的区域代理服务器纳入您的子策略中，子策略可以是服务器也可以是其他区域策略组．
最后，您可以通过BoxJs设置策略名和子策略名，或者手动填入脚本.

如需搜索指定地区番剧, 可在搜索框添加后缀" 港", " 台", " 中". 例如: 进击的巨人 港

QX用户注: 使用切换地区功能请确保您的QX=>其他设置=>温和策略机制处于关闭状态, 以及填写策略名和子策略名时注意大小写.
