The parameter should be a char * to a zero terminated string which +must be URL-encoded in the following format: "https://host:port/path". It MUST +specify a HTTPS URL. + +libcurl doesn't validate the syntax or use this variable until the transfer is +issued. Even if you set a crazy value here, \fIcurl_easy_setopt(3)\fP will +still return \fICURLE_OK\fP. + +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 \fICURLOPT_RESOLVE(3)\fP. + +Disable DOH use again by setting this option to NULL. +.SH DEFAULT +NULL - there is no default DOH URL. If this option isn't set, libcurl will use +the default name resolver. +.SH PROTOCOLS +All +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); + curl_easy_setopt(curl, CURLOPT_DOH_URL, "https://dns.example.com"); + curl_easy_perform(curl); +} +.fi +.SH AVAILABILITY +Added in 7.62.0 +.SH RETURN VALUE +Returns CURLE_OK on success or CURLE_OUT_OF_MEMORY if there was insufficient +heap space. + +Note that \fIcurl_easy_setopt(3)\fP won't actually parse the given string so +given a bad DOH URL, curl will not detect a problem until it tries to resolve +a name with it. +.SH "SEE ALSO" +.BR CURLOPT_VERBOSE "(3), " CURLOPT_RESOLVE "(3), " |
