使用的配置文件

log:
    level: info
plugins:
    - args:
        upstreams:
            - addr: 114.114.114.114
      tag: forward
      type: forward
    - args:
        entries:
          - path: /dns-query
            exec: forward
        listen: "@some_uds"
      tag: http_server
      type: http_server
