NAME
curl_url_get - extract a part from a URL
SYNOPSIS
#include <curl/curl.h>
CURLUcode curl_url_get(CURLU *url,
CURLUPart what,
char **part,
unsigned int flags)
DESCRIPTION
Given the url handle of an already parsed URL, this function lets the
user extract individual pieces from it.
The what argument should be the particular part to extract (see list
below) and part points to a 'char *' to get updated to point to a newly
allocated string with the contents.
The flags argument is a bitmask with individual features.
The returned part pointer must be freed with curl_free(3) after use.
FLAGS
The flags argument is zero, one or more bits set in a bitmask.
CURLU_DEFAULT_PORT
If the handle has no port stored, this option will make
curl_url_get(3) return the default port for the used scheme.
CURLU_DEFAULT_SCHEME
If the handle has no scheme stored, this option will make
curl_url_get(3) return the default scheme instead of error.
CURLU_NO_DEFAULT_PORT
Instructs curl_url_get(3) to not return a port number if it
matches the default port for the scheme.
CURLU_URLDECODE
Asks curl_url_get(3) to URL decode the contents before returning
it. It will not attempt to decode the scheme, the port number or
the full URL. ´ The query component will also get plus-to-
space conversion as a bonus when this bit is set.
Note that this URL decoding is charset unaware and you will get
a zero terminated string back with data that could be intended
for a particular encoding.
If there's any byte values lower than 32 in the decoded string,
the get operation will return an error instead.
CURLU_URLENCODE
If set, will make curl_url_get(3) URL encode the host name part
when a full URL is retrieved. If not set (default), libcurl
returns the URL with the host name "raw" to support IDN names to
appear as-is. IDN host names are typically using non-ASCII bytes
that otherwise will be percent-encoded.
Note that even when not asking for URL encoding, the '%' (byte
37) will be URL encoded to make sure the host name remains
valid.
PARTS
CURLUPART_URL
When asked to return the full URL, curl_url_get(3) will return a
normalized and possibly cleaned up version of what was previ‐
ously parsed.
CURLUPART_SCHEME
Scheme cannot be URL decoded on get.
CURLUPART_USER
CURLUPART_PASSWORD
CURLUPART_OPTIONS
CURLUPART_HOST
The host name. If it is an IPv6 numeric address, the zone id
will not be part of it but is provided separately in CURLU‐
PART_ZONEID. IPv6 numerical addresses are returned within brack‐
ets ([]).
CURLUPART_ZONEID
If the host name is a numeric IPv6 address, this field might
also be set.
CURLUPART_PORT
Port cannot be URL decoded on get.
CURLUPART_PATH
part will be '/' even if no path is supplied in the URL.
CURLUPART_QUERY
The initial question mark that denotes the beginning of the
query part is a delimiter only. It is not part of the query
contents.
A not-present query will lead part to be set to NULL. A zero-
length query will lead part to be set to a zero-length string.
The query part will also get pluses converted to space when
asked to URL decode on get with the CURLU_URLDECODE bit.
CURLUPART_FRAGMENT
EXAMPLE
CURLUcode rc;
CURLU *url = curl_url();
rc = curl_url_set(url, CURLUPART_URL, "https://example.com", 0);
if(!rc) {
char *scheme;
rc = curl_url_get(url, CURLUPART_SCHEME, &scheme, 0);
if(!rc) {
printf("the scheme is %s\n", scheme);
curl_free(scheme);
}
curl_url_cleanup(url);
}
AVAILABILITY
Added in 7.62.0. CURLUPART_ZONEID was added in 7.65.0.
RETURN VALUE
Returns a CURLUcode error value, which is CURLUE_OK (0) if everything
went fine. See the libcurl-errors(3) man page for the full list with
descriptions.
If this function returns an error, no URL part is returned.
