CURLOPT_DOH_URL(3)

CURLOPT_DOH_URL(3)         curl_easy_setopt options         CURLOPT_DOH_URL(3)

NAME
       CURLOPT_DOH_URL - provide the DNS-over-HTTPS URL

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_URL, char *URL);

DESCRIPTION
       Pass  in  a pointer to a URL for the DoH server to use for name resolv‐
       ing. The parameter should be a char * to a null-terminated string which
       must be URL-encoded in the following format:  "https://host:port/path".
       It MUST specify an HTTPS URL.

       libcurl  does  not  validate  the syntax or use this variable until the
       transfer is issued. Even if you set a crazy value  here,  curl_easy_se‐
       topt(3) will still return CURLE_OK.

       curl sends POST requests to the given DNS-over-HTTPS URL.

       To  find  the DoH server itself, which might be specified using a name,
       libcurl will use the default name lookup function.  You  can  bootstrap
       that  by  providing  the  address  for  the DoH server with CURLOPT_RE‐
       SOLVE(3).

       Disable DoH use again by setting this option to NULL.

INHERIT OPTIONS
       DoH lookups use SSL and some SSL settings from your transfer are inher‐
       ited, like CURLOPT_SSL_CTX_FUNCTION(3).

       The hostname and peer certificate verification settings are not  inher‐
       ited but can be controlled separately via CURLOPT_DOH_SSL_VERIFYHOST(3)
       and CURLOPT_DOH_SSL_VERIFYPEER(3).

       A set CURLOPT_OPENSOCKETFUNCTION(3) callback is not inherited.

KNOWN BUGS
       Even  when DoH is set to be used with this option, there are still some
       name resolves that are performed without it, using the default name re‐
       solver mechanism. This includes name resolves done  for  CURLOPT_INTER‐
       FACE(3),  CURLOPT_FTPPORT(3),  a  proxy type set to CURLPROXY_SOCKS4 or
       CURLPROXY_SOCKS5 and probably some more.

DEFAULT
       NULL - there is no default DoH URL. If this option is not set,  libcurl
       will use the default name resolver.

PROTOCOLS
       All

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
         curl_easy_setopt(curl, CURLOPT_DOH_URL, "https://dns.example.com");
         curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.62.0

RETURN VALUE
       Returns  CURLE_OK on success or CURLE_OUT_OF_MEMORY if there was insuf‐
       ficient heap space.

       Note that curl_easy_setopt(3) will  not  immediately  parse  the  given
       string  so when given a bad DoH URL, libcurl might not detect the prob‐
       lem until it later tries to resolve a name with it.
