/**
* DNS查询
* /dns/:upstream:/:way:/:host:?name=xxx&type=xxx&edns_client_subnet=x.x.x.x
* /dns
* /dns/get
* /dns/ali/get/host
*
参数 参数用途
name 需要解析的域名
type 解析形式,A or AAAA or CNAME等等
edns_client_subnet EDNS的ip,默认开启为本机ip,开启此项功能可提高解析精准度.注:此功能在upstream为CloudFlare的情况下失效,因为CloudFlare为了用户隐私关闭此功能.
way 获取方式，默认doh方式，可使用以下参数: doh get
host 是否转化为host格式[仅在type为A或AAAA格式下生效]
upstream 上游DNS解析,默认为CloudFlare 回源<1ms
可使用以下参数:
google使用谷歌DNS,回源1~10ms
ali使用阿里CDN,回源50~150ms
dnspod使用腾讯云DNSPODCDN,回源10~80ms
注：DoH 推荐直接选用https://dns.alidns.com/dns-query，而不是用本API的反代接口
