Does APISIX Plugin support using var in configurations?

[chenjizheng]

希望插件配置值支持变量获取，如uri：${ctx.var.uri}

Hi @chenjizheng, just to make sure, you'd like to use vars in your custom plugin? AFAIK, the traffic-split[1] plugin supports using vars, you could have a check how it implement. See https://github.com/apache/apisix/blob/master/apisix/plugins/traffic-split.lua
