|
|
.SH NAME
|
|
curl_url_get - extract a part from a URL
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
|
|
.nf
|
|
CURLUcode curl_url_get(CURLU *url,
|
|
CURLUPart what,
|
|
char **part,
|
|
unsigned int flags)
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Given the \fIurl\fP handle of an already parsed URL, this function lets the
|
|
user extract individual pieces from it.
|
|
|
|
The \fIwhat\fP argument should be the particular part to extract (see list
|
|
below) and \fIpart\fP points to a 'char *' to get updated to point to a newly
|
|
allocated string with the contents.
|
|
|
|
The \fIflags\fP argument is a bitmask with individual features.
|
|
|
|
The returned part pointer must be freed with \fIcurl_free(3)\fP after use.
|
|
.SH FLAGS
|
|
The flags argument is zero, one or more bits set in a bitmask.
|
|
.IP CURLU_DEFAULT_PORT
|
|
If the handle has no port stored, this option will make \fIcurl_url_get(3)\fP
|
|
return the default port for the used scheme.
|
|
.IP CURLU_DEFAULT_SCHEME
|
|
If the handle has no scheme stored, this option will make
|
|
\fIcurl_url_get(3)\fP return the default scheme instead of error.
|
|
.IP CURLU_NO_DEFAULT_PORT
|
|
Instructs \fIcurl_url_get(3)\fP to not return a port number if it matches the
|
|
default port for the scheme.
|
|
.IP CURLU_URLDECODE
|
|
Asks \fIcurl_url_get(3)\fP 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.
|
|
.SH PARTS
|
|
.IP CURLUPART_URL
|
|
When asked to return the full URL, \fIcurl_url_get(3)\fP will return a
|
|
normalized and possibly cleaned up version of what was previously parsed.
|
|
.IP CURLUPART_SCHEME
|
|
Scheme cannot be URL decoded on get.
|
|
.IP CURLUPART_USER
|
|
.IP CURLUPART_PASSWORD
|
|
.IP CURLUPART_OPTIONS
|
|
.IP CURLUPART_HOST
|
|
The host name. If it is an IPv6 numeric address, the zoneid will not be part
|
|
of it but is provided separately in \fICURLUPART_ZONEID\fP. IPv6 numerical
|
|
addresses are returned within brackets ([]).
|
|
.IP CURLUPART_ZONEID
|
|
If the host name is a numeric IPv6 address, this field might also be set.
|
|
.IP CURLUPART_PORT
|
|
Port cannot be URL decoded on get.
|
|
.IP CURLUPART_PATH
|
|
.IP CURLUPART_QUERY
|
|
The query part will also get pluses converted to space when asked to URL
|
|
decode on get with the CURLU_URLDECODE bit.
|
|
.IP CURLUPART_FRAGMENT
|
|
.SH RETURN VALUE
|
|
Returns a CURLUcode error value, which is CURLUE_OK (0) if everything went
|
|
fine.
|
|
|
|
If this function returns an error, no URL part is returned.
|
|
.SH EXAMPLE
|
|
.nf
|
|
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);
|
|
}
