我正在运行最新版本的curl (7.76.1)。
我已经设置了自己的 dnsdist 服务器/doh 代理，它查询我也设置的bind9解析器。
让curl 仅返回已解析的IP 的正确语法是什么？
当我运行以下命令时，返回的只是 example.com 的 html。我不想要 html。我想要解析的 DNS IP 地址。
curl --doh-insecure --doh-url https://10.10.10.10/dns-query http://www.example.com如果我以详细输出运行，我可以看到以下内容。
* DOH A: 93.184.216.34
* DOH AAAA: 2606:2800:0220:0001:0248:1893:25c8:1946
如何让curl 只返回DNS dig 响应，而不返回对相关站点的HTTP GET 请求的响应？
这是完整的输出：

curl -vH "accept: application/dns-json" "https://cloudflare-dns.com/dns-query?name=example.com&type=AAAA"
应该会得到你想要的 DNS 结果
curl 返回网页。
要获取IP地址，最好使用命令安装DNSLOOKUP工具
#snap install dnslookup
安装后，使用以下命令获取IP地址
#VERIFY=0 dnslookup www.example.com https://10.10.10.10/dns-query
如果你有有效的证书，VERIFY=0可以去掉。
#dnslookup www.example.com https://dns.google/dns-query
用户可以通过
--doh-urlcurl --doh-url https://cloudflare-dns.com/dns-query https://github.com
Dig 支持这一点。示例：
dig @1.1.1.1 +https public.tls-ech.dev https
https://manpages.ubuntu.com/manpages/kinetic/man1/dig.1.html
我知道您想使用
curldigdig+httpsdig +https @1.1.1.1 example.com
