----------------------------------------
[Script]
Sub_info = type=generic,timeout=10,script-path=https://raw.githubusercontent.com/smartmimi/conf/master/surge/sub_info_panel.js,script-update-interval=0
[Panel]
Sub_info = script-name=Sub_info
----------------------------------------
可选参数 reset_day，后面的数字替换成流量每月重置的日期，如1号就写1，8号就写8。如"&reset_day=8",不加该参数不显示流量重置信息。
可选参数 expire，机场链接不带expire信息的，可以手动传入expire参数，如"&expire=2022-02-01",注意一定要按照yyyy-MM-dd的格式。
可选参数"title=xxx" 可以自定义标题。
