NAME
curl_url_set - set a URL part
SYNOPSIS
#include <curl/curl.h>
CURLUcode curl_url_set(CURLU *url,
CURLUPart part,
const char *content,
unsigned int flags)
DESCRIPTION
Given the url handle of an already parsed URL, this function lets the
user set/update individual pieces of it.
The part argument should identify the particular URL part (see list
below) to set or change, with content pointing to a null-terminated
string with the new contents for that URL part. The contents should be
in the form and encoding they'd use in a URL: URL encoded.
The application does not have to keep content around after a successful
call.
Setting a part to a NULL pointer will effectively remove that part's
contents from the CURLU handle.
By default, this API only accepts URLs using schemes for protocols that
are supported built-in. To make libcurl parse URLs generically even for
schemes it does not know about, the CURLU_NON_SUPPORT_SCHEME flags bit
must be set. Otherwise, this function returns CURLUE_UNSUPPORTED_SCHEME
on URL schemes it does not recognize.
The flags argument is a bitmask with independent features.
PARTS
CURLUPART_URL
Allows the full URL of the handle to be replaced. If the handle
already is populated with a URL, the new URL can be relative to
the previous.
When successfully setting a new URL, relative or absolute, the
handle contents will be replaced with the information of the
newly set URL.
Pass a pointer to a null-terminated string to the url parameter.
The string must point to a correctly formatted "RFC 3986+" URL
or be a NULL pointer.
CURLUPART_SCHEME
Scheme cannot be URL decoded on set. libcurl only accepts set‐
ting schemes up to 40 bytes long.
CURLUPART_USER
CURLUPART_PASSWORD
CURLUPART_OPTIONS
CURLUPART_HOST
The host name. If it is IDNA the string must then be encoded as
your locale says or UTF-8 (when WinIDN is used). If it is a
bracketed IPv6 numeric address it may contain a zone id (or you
can use CURLUPART_ZONEID).
CURLUPART_ZONEID
If the host name is a numeric IPv6 address, this field can also
be set.
CURLUPART_PORT
Port cannot be URL encoded on set. The given port number is pro‐
vided as a string and the decimal number must be between 1 and
65535. Anything else will return an error.
CURLUPART_PATH
If a path is set in the URL without a leading slash, a slash
will be inserted automatically when this URL is read from the
handle.
CURLUPART_QUERY
The query part will also get spaces converted to pluses when
asked to URL encode on set with the CURLU_URLENCODE bit.
If used together with the CURLU_APPENDQUERY bit, the provided
part is appended on the end of the existing query.
The question mark in the URL is not part of the actual query
contents.
CURLUPART_FRAGMENT
The hash sign in the URL is not part of the actual fragment con‐
tents.
FLAGS
The flags argument is zero, one or more bits set in a bitmask.
CURLU_APPENDQUERY
Can be used when setting the CURLUPART_QUERY component. The pro‐
vided new part will then instead be appended at the end of the
existing query - and if the previous part did not end with an
ampersand (&), an ampersand gets inserted before the new
appended part.
When CURLU_APPENDQUERY is used together with CURLU_URLENCODE,
the first '=' symbol will not be URL encoded.
CURLU_NON_SUPPORT_SCHEME
If set, allows curl_url_set(3) to set a non-supported scheme.
CURLU_URLENCODE
When set, curl_url_set(3) URL encodes the part on entry, except
for scheme, port and URL.
When setting the path component with URL encoding enabled, the
slash character will be skipped.
The query part gets space-to-plus conversion before the URL con‐
version.
This URL encoding is charset unaware and will convert the input
on a byte-by-byte manner.
CURLU_DEFAULT_SCHEME
If set, will make libcurl allow the URL to be set without a
scheme and then sets that to the default scheme: HTTPS. Over‐
rides the CURLU_GUESS_SCHEME option if both are set.
CURLU_GUESS_SCHEME
If set, will make libcurl allow the URL to be set without a
scheme and it instead "guesses" which scheme that was intended
based on the host name. If the outermost sub-domain name matches
DICT, FTP, IMAP, LDAP, POP3 or SMTP then that scheme will be
used, otherwise it picks HTTP. Conflicts with the
CURLU_DEFAULT_SCHEME option which takes precedence if both are
set.
CURLU_NO_AUTHORITY
If set, skips authority checks. The RFC allows individual
schemes to omit the host part (normally the only mandatory part
of the authority), but libcurl cannot know whether this is per‐
mitted for custom schemes. Specifying the flag permits empty
authority sections, similar to how file scheme is handled.
CURLU_PATH_AS_IS
When set for CURLUPART_URL, this makes libcurl skip the normal‐
ization of the path. That is the procedure where curl otherwise
removes sequences of dot-slash and dot-dot etc. The same option
used for transfers is called CURLOPT_PATH_AS_IS(3).
CURLU_ALLOW_SPACE
If set, a the URL parser allows space (ASCII 32) where possible.
The URL syntax does normally not allow spaces anywhere, but they
should be encoded as %20 or '+'. When spaces are allowed, they
are still not allowed in the scheme. When space is used and
allowed in a URL, it will be stored as-is unless CURLU_URLENCODE
is also set, which then makes libcurl URL-encode the space
before stored. This affects how the URL will be constructed when
curl_url_get(3) is subsequently used to extract the full URL or
individual parts. (Added in 7.78.0)
EXAMPLE
CURLUcode rc;
CURLU *url = curl_url();
rc = curl_url_set(url, CURLUPART_URL, "https://example.com", 0);
if(!rc) {
char *scheme;
/* change it to an FTP URL */
rc = curl_url_set(url, CURLUPART_SCHEME, "ftp", 0);
}
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.
A URL string passed on to curl_url_set(3) for the CURLUPART_URL part,
must be shorter than 8000000 bytes otherwise it returns CURLUE_MAL‐
FORMED_INPUT (added in 7.65.0).
If this function returns an error, no URL part is set.
