Represent and parse a URL.
A prototypical URL looks like:
protocol:/user:password@hostname:port/path/to/file.ext#reference |
KURL has some restrictions regarding the path encoding. KURL works internally with the decoded path and and encoded query. For example,
http://localhost/cgi-bin/test%20me.pl?cmd=Hello%20you |
would result in a decoded path "/cgi-bin/test me.pl" and in the encoded query "?cmd=Hello%20you". Since path is internally always encoded you may not use "%00" in the path, although this is OK for the query.

KURL ( const QString& url, int encoding_hint = 0 )
| KURL |
Usual constructor, to construct from a string.
Parameters:
url | A URL, not a filename. If the URL does not have a protocol part, "file:" is assumed. It is dangerous to feed unix filenames into this function, this will work most of the time but not always. For example "/home/Torben%20Weis" will be considered a URL pointing to the file "/home/Torben Weis" instead of to the file "/home/Torben%20Weis". This means that if you have a usual UNIX like path you should not use this constructor. Instead create an empty url and set the path by using setPath(). |
encoding_hint | Reserved, should be 0. |
KURL ( const char * url, int encoding_hint = 0 )
| KURL |
Constructor taking a char * url
, which is an _encoded_ representation
of the URL, exactly like the usual constructor. This is useful when
then URL, in its encoded form, is strictly ascii.
KURL ( const KURL& u )
| KURL |
Copy constructor
KURL ( const QUrl &u )
| KURL |
Convert from a QUrl.
KURL ( const KURL& _baseurl, const QString& _rel_url, int encoding_hint=0 )
| KURL |
Constructor allowing relative URLs.
Parameters:
_baseurl | The base url. |
_rel_url | A relative or absolute URL.
If this is an absolute URL then _baseurl will be ignored.
If this is a relative URL it will be combined with _baseurl .
Note that _rel_url should be encoded too, in any case.
So do NOT pass a path here (use setPath or addPath instead).
|
encoding_hint | Reserved, should be 0. |
QString protocol ()
| protocol |
[const]
Retrieve the protocol for the URL (i.e., file, http, etc.).
void setProtocol ( const QString& _txt )
| setProtocol |
Set the protocol for the URL (i.e., file, http, etc.)
QString user ()
| user |
[const]
Retrieve the decoded user name (login, user id, ...) included in the URL.
void setUser ( const QString& _txt )
| setUser |
Set the user name (login, user id, ...) included the URL.
Special characters in the user name will appear encoded in the URL.
bool hasUser ()
| hasUser |
[const]
Test to see if this URL has a user name included in it.
QString pass ()
| pass |
[const]
Retrieve the decoded password (corresponding to user()) included in the URL.
void setPass ( const QString& _txt )
| setPass |
Set the password (corresponding to user()) included in the URL.
Special characters in the password will appear encoded in the URL.
bool hasPass ()
| hasPass |
[const]
Test to see if this URL has a password included in it.
QString host ()
| host |
[const]
Retrieve the decoded hostname included in the URL.
void setHost ( const QString& _txt )
| setHost |
Set the hostname included in the URL.
Special characters in the hostname will appear encoded in the URL.
bool hasHost ()
| hasHost |
[const]
Test to see if this URL has a hostname included in it.
unsigned short int port ()
| port |
[const]
Retrieve the port number included in the URL. If there is no port number specified in the URL, returns 0.
void setPort ( unsigned short int _p )
| setPort |
Set the port number included in the URL.
QString path ()
| path |
[const]
Returns: The current decoded path. This does not include the query.
QString path ( int _trailing )
| path |
[const]
Parameters:
_trailing | May be ( -1, 0 +1 ). -1 strips a trailing '/', +1 adds a trailing '/' if there is none yet and 0 returns the path unchanged. If the URL has no path, then no '/' is added anyway. And on the other side: If the path is "/", then this character won't be stripped. Reason: "ftp://weis@host" means something completely different than "ftp://weis@host/". So adding or stripping the '/' would really alter the URL, while "ftp://host/path" and "ftp://host/path/" mean the same directory. |
Returns: The current decoded path. This does not include the query.
void setPath ( const QString& path )
| setPath |
path This is considered to be decoded. This means: %3f does not become decoded and the ? does not indicate the start of the query part. The query is not changed by this function.
bool hasPath ()
| hasPath |
[const]
Test to see if this URL has a path is included in it.
void cleanPath ()
| cleanPath |
Removes all multiple directory separators ('/') and resolves any "." or ".." found in the path. Calls QDir::cleanDirPath but saves the trailing slash if any.
void cleanPath (bool cleanDirSeparator)
| cleanPath |
Same as above except it takes a flag that allows you to ignore the clean up of the multiple directory separators.
Some servers seem not to like the removal of extra '/' eventhough it is against the specification in RFC 2396.
void setEncodedPathAndQuery ( const QString& _txt, int encoding_hint = 0 )
| setEncodedPathAndQuery |
This is useful for HTTP. It looks first for '?' and decodes then. The encoded path is the concatenation of the current path and the query.
Parameters:
encoding_hint | Reserved, should be 0. |
QString encodedPathAndQuery ( int _trailing = 0, bool _no_empty_path = false, int encoding_hint = 0)
| encodedPathAndQuery |
[const]
Parameters:
_no_empty_path | If set to true then an empty path is substituted by "/". |
encoding_hint | Reserved, should be 0. |
Returns: The concatenation if the encoded path , '?' and the encoded query.
void setQuery ( const QString& _txt, int encoding_hint = 0)
| setQuery |
The query should start with a '?'. If it doesn't '?' is prepended.
Parameters:
_txt | This is considered to be encoded. This has a good reason: The query may contain the 0 character. |
encoding_hint | Reserved, should be 0. |
QString query ()
| query |
[const]
Returns: The encoded query. This has a good reason: The query may contain the 0 character. If a query is present it always starts with a '?'. A single '?' means an empty query. An empty string means no query.
QString ref ()
| ref |
[const]
The reference is never decoded automatically.
void setRef ( const QString& _txt )
| setRef |
Set the reference part (everything after '#').
Parameters:
_txt | is considered encoded. |
bool hasRef ()
| hasRef |
[const]
Returns: true
if the reference part of the URL is not empty. In a URL like
http://www.kde.org/kdebase.tar#tar:/README it would return true
, too.
QString htmlRef ()
| htmlRef |
[const]
Returns: The HTML-style reference.
QString encodedHtmlRef ()
| encodedHtmlRef |
[const]
Returns: The HTML-style reference in its original form.
void setHTMLRef ( const QString& _ref )
| setHTMLRef |
Set the HTML-style reference.
Parameters:
_ref | This is considered to be not encoded in contrast to setRef() |
See also: htmlRef()
bool hasHTMLRef ()
| hasHTMLRef |
[const]
Returns: true
if the URL has an HTML-style reference.
See also: htmlRef()
bool isValid ()
| isValid |
[const]
Returns: false
if the URL is malformed. This function does not test
whether sub URLs are well-formed, too.
bool isMalformed ()
| isMalformed |
[const]
bool isLocalFile ()
| isLocalFile |
[const]
Returns: true
if the file is a plain local file and has no filter protocols
attached to it.
bool hasSubURL ()
| hasSubURL |
[const]
Returns: true
if the file has at least one sub URL.
Use split() to get the sub URLs.
void addPath ( const QString& _txt )
| addPath |
Add to the current path.
Assumes that the current path is a directory. _txt
is appended to the
current path. The function adds '/' if needed while concatenating.
This means it does not matter whether the current path has a trailing
'/' or not. If there is none, it becomes appended. If _txt
has a leading '/' then this one is stripped.
Parameters:
_txt | This is considered to be decoded |
void setFileName ( const QString&_txt )
| setFileName |
In comparison to addPath() this function does not assume that the current path is a directory. This is only assumed if the current path ends with '/'.
Any reference is reset.
Parameters:
_txt | This is considered to be decoded. If the current path ends with '/'
then _txt ist just appended, otherwise all text behind the last '/'
in the current path is erased and _txt is appended then. It does
not matter whether _txt starts with '/' or not.
|
QString fileName ( bool _ignore_trailing_slash_in_path = true )
| fileName |
[const]
Parameters:
_ignore_trailing_slash_in_path | This tells whether a trailing '/' should be ignored. This means that the function would return "torben" for file:/hallo/torben/ and file:/hallo/torben. If the flag is set to false, then everything behind the last '/' is considered to be the filename. |
Returns: The filename of the current path. The returned string is decoded.
QString filename ( bool _ignore_trailing_slash_in_path = true )
| filename |
[const]
QString directory ( bool _strip_trailing_slash_from_result = true,
bool _ignore_trailing_slash_in_path = true )
| directory |
[const]
Parameters:
_strip_trailing_slash_from_result | tells whether the returned result should end with '/' or not. If the path is empty or just "/" then this flag has no effect. |
_ignore_trailing_slash_in_path | means that file:/hallo/torben and file:/hallo/torben/" would both return /hallo/ or /hallo depending on the other flag |
Returns: The directory part of the current path. Everything between the last and the second last '/' is returned. For example file:/hallo/torben/ would return "/hallo/torben/" while file:/hallo/torben would return "hallo/". The returned string is decoded.
bool cd ( const QString& _dir )
| cd |
Change directory by descending into the given directory.
It is assumed the current URL represents a directory.
If dir
starts with a "/" the
current URL will be "protocol://host/dir" otherwise _dir
will
be appended to the path. _dir
can be ".."
This function won't strip protocols. That means that when you are in
file:/dir/dir2/my.tgz#tar:/ and you do cd("..") you will
still be in file:/dir/dir2/my.tgz#tar:/
Returns: true
QString url ( int _trailing = 0 )
| url |
[const]
Parameters:
_trailing | This may be ( -1, 0 +1 ). -1 strips a trailing '/' from the path, +1 adds a trailing '/' if there is none yet and 0 returns the path unchanged. |
Returns: The complete URL, with all escape sequences intact. Example: http://localhost:8080/test.cgi?test=hello%20world&name=fred
QString url ( int _trailing, int encoding_hint )
| url |
[const]
Parameters:
_trailing | This may be ( -1, 0 +1 ). -1 strips a trailing '/' from the path, +1 adds a trailing '/' if there is none yet and 0 returns the path unchanged. |
encoding_hint | The charset to use for encoding (see QFont::Charset). |
Returns: The complete URL, with all escape sequences intact, encoded in a given charset. This is used in particular for encoding URLs in UTF-8 before using them in a drag and drop operation.
QString prettyURL ( int _trailing = 0)
| prettyURL |
[const]
Returns: A human readable URL, with no non-necessary encodings/escaped characters. Example: http://localhost:8080/test.cgi?test=hello world&name=fred
bool isEmpty ()
| isEmpty |
[const]
Test to see if the KURL is empty.
KURL upURL ( )
| upURL |
[const]
This function is useful to implement the "Up" button in a file manager for example. cd() never strips a sub-protocol. That means that if you are in file:/home/x.tgz#gzip:/#tar:/ and hit the up button you expect to see file:/home. The algorithm tries to go up on the right-most URL. If that is not possible it strips the right most URL. It continues stripping URLs.

[const]
bool cmp ( const KURL &u, bool ignore_trailing = false )
| cmp |
[const]
Compare this url with u
Parameters:
ignore_trailing | set to true to ignore trailing '/' characters. |
Returns: true if both urls are the same
See also: operator==., This, function, should, be, used, if, you, want, to, ignore, trailing, '/', characters.
bool isParentOf ( const KURL& u )
| isParentOf |
[const]
Returns: true if this url is a parent of u
(or the same URL as u
)
For instance, ftp://host/dir/ is a parent of ftp://host/dir/subdir/subsubdir/.
List split ( const QString& _url )
| split |
[static]
Splits nested URLs like file:/home/weis/kde.tgz#gzip:/#tar:/kdebase A URL like http://www.kde.org#tar:/kde/README.hml#ref1 will be split in http://www.kde.org and tar:/kde/README.html#ref1. That means in turn that "#ref1" is an HTML-style reference and not a new sub URL. Since HTML-style references mark a certain position in a document this reference is appended to every URL. The idea behind this is that browsers, for example, only look at the first URL while the rest is not of interest to them.
Parameters:
_url | The URL that has to be split. |
Returns: An empty list on error or the list of split URLs.
List split ( const KURL& _url )
| split |
[static]
A convenience function.
KURL join ( const List& _list )
| join |
[static]
Reverses split(). Only the first URL may have a reference. This reference is considered to be HTML-like and is appended at the end of the resulting joined URL.
