大佬，你的这个解析方式很巧妙，非常适合处理nginx配置，最近正在研究
在学习的过程中，发现一个问题，通常include下会放很多server的配置，如何方便解析和修改数据呢，由于 Children是个接口类型，要解析下层只能类型断言，这现一层层断言层次比较深，有什么好办法不

`
config, _ := resolv.Load("../test/nginx.conf")

for _, k := range config.Children {
	switch k.(type) {
	//case *resolv.Events:
	//k.(*resolv.Events).Add(&resolv.Key{Name: "xx", Value: "yy"})
	case *resolv.Http:
		for _, p := range k.(*resolv.Http).Children {
			switch p.(type) {
			case *resolv.Include:
				for _, q := range p.(*resolv.Include).Children {
					switch q.(type) {
					case *resolv.Config:
						fmt.Println(q.(*resolv.Config).Name, q.(*resolv.Config).Value)
					}
				}
			}
		}
	}
}

`

server_name ~^xxx[1-4]\.xxxxx\.com$
另外，如果server_name中使用正则，如上面这样，json.Marshal(conf) 会报错：
json: error calling MarshalJSON for type *resolv.Key: invalid character '.' in string escape code
看能解决不

有相关使用手册吗？

当前Configuration指提供Json等方法输出序列化的nginx配置，能否提供将 type configuration struct {
config *parser.Config
rwLocker *sync.RWMutex
loopPreventer loop_preventer.LoopPreventer
utils.ConfigFingerprinter
}中的config导出的接口

json.Marshal可以直接将Config编码为json格式，如何将json解码成Config结构体呢？

请问 , 这个怎么使用 , 有相关文档吗

            ngx.log(ngx.ERR, emsg, err)

}
