Detailed Description

Represents and parses a URL.

A prototypical URL looks like:

   protocol:/user:password@hostname:port/path/to/file.extreference
 

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.

Constructor & Destructor Documentation

KURL::KURL  
 

Constructs an empty URL.

KURL::~KURL  
 

Destructs the KURL object.

KURL::KURL const QString &    url,
int    encoding_hint = 0
 

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  MIB of original encoding of URL.
See also:
QTextCodec::mibEnum()

KURL::KURL const char *    url,
int    encoding_hint = 0
 

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.

Parameters:
url  A encoded URL. If the URL does not have a protocol part, "file:" is assumed.
encoding_hint  MIB of original encoding of URL.
See also:
QTextCodec::mibEnum()

KURL::KURL const QCString &    url,
int    encoding_hint = 0
 

Constructor taking a QCString 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.

Parameters:
url  A encoded URL. If the URL does not have a protocol part, "file:" is assumed.
encoding_hint  MIB of original encoding of URL.
See also:
QTextCodec::mibEnum()

KURL::KURL const KURL &    u
 

Copy constructor.

Parameters:
u  the KURL to copy

KURL::KURL const QUrl &    u
 

Converts from a QUrl.

Parameters:
u  the QUrl

KURL::KURL const KURL &    _baseurl,
const QString &    _rel_url,
int    encoding_hint = 0
 

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  MIB of original encoding of URL.

QTextCodec::mibEnum()


Member Function Documentation

void KURL::addPath const QString &    _txt
 

Adds 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  The text to add. It is considered to be decoded.

void KURL::addQueryItem const QString &    _item,
const QString &    _value,
int    encoding_hint = 0
 

Add an additional query item. To replace an existing query item, the item should first be removed with removeQueryItem()

Parameters:
_item  Name of item to add
_value  Value of item to add
encoding_hint  MIB of encoding to use for _value.
See also:
QTextCodec::mibEnum()

void KURL::adjustPath int    _trailing
 

Add or remove a trailing slash to/from the path.

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.

bool KURL::cd const QString &    _dir
 

Changes the 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:/

Parameters:
_dir  the directory to change to
Returns:
true if successful

void KURL::cleanPath bool    cleanDirSeparator = true
 

Resolves "." and ".." components in path. Some servers seem not to like the removal of extra '/' even though it is against the specification in RFC 2396.

Parameters:
cleanDirSeparator  if true, occurrances of consecutive directory separators (e.g. /foo//bar) are cleaned up as well.

bool KURL::cmp const KURL &    u,
bool    ignore_trailing = false
const
 

The same as equals(), just with a less obvious name. Compares 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.
Deprecated:

QString KURL::decode_string const QString &    str,
int    encoding_hint = 0
[static]
 

Convenience function.

Decode %-style encoding and convert from local encoding to unicode.

Reverse of encode_string()

Parameters:
str  String to decode (can be QString::null).
encoding_hint  MIB of original encoding of str .
See also:
QTextCodec::mibEnum()

QString KURL::directory bool    _strip_trailing_slash_from_result = true,
bool    _ignore_trailing_slash_in_path = true
const
 

Returns the directory of the path.

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. QString::null is returned when there is no path.

QString KURL::encode_string const QString &    str,
int    encoding_hint = 0
[static]
 

Convenience function.

Convert unicoded string to local encoding and use %-style encoding for all common delimiters / non-ascii characters.

Parameters:
str  String to encode (can be QString::null).
encoding_hint  MIB of encoding to use.
See also:
QTextCodec::mibEnum()
Returns:
the encoded string

QString KURL::encode_string_no_slash const QString &    str,
int    encoding_hint = 0
[static]
 

Convenience function.

Convert unicoded string to local encoding and use %-style encoding for all common delimiters / non-ascii characters as well as the slash '/'.

Parameters:
str  String to encode
encoding_hint  MIB of encoding to use.
See also:
QTextCodec::mibEnum()

QString KURL::encodedHtmlRef  
 

Returns the HTML reference (the part of the URL after "#") in encoded form.

Returns:
The HTML-style reference in its original form.

QString KURL::encodedPathAndQuery int    _trailing = 0,
bool    _no_empty_path = false,
int    encoding_hint = 0
const
 

Returns the encoded path and the query.

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.
_no_empty_path  If set to true then an empty path is substituted by "/".
encoding_hint  MIB of desired encoding of URL.
See also:
QTextCodec::mibEnum()
Returns:
The concatenation if the encoded path , '?' and the encoded query.

bool KURL::equals const KURL &    u,
bool    ignore_trailing = false
const
 

Compares 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.
Since:
3.1

QString KURL::fileEncoding  
 

Returns encoding information from url, the content of the "charset" parameter.

Returns:
An encoding suitable for QTextCodec::codecForName() or QString::null if not encoding was specified.

QString KURL::fileName bool    _ignore_trailing_slash_in_path = true const
 

Returns the filename of the path.

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. Null if there is no file (and thus no path).

KURL KURL::fromPathOrURL const QString &    text [static]
 

Creates a KURL object from a QString representing either an absolute path or a real URL. Use this method instead of

 QString someDir = ...
 KURL url = someDir;

encoding_hint  MIB of original encoding of _txt .
See also:
QTextCodec::mibEnum()

void KURL::setEncodedPathAndQuery const QString &    _txt,
int    encoding_hint = 0
 

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:
_txt  the new path and query.
encoding_hint  MIB of original encoding of _txt .
See also:
QTextCodec::mibEnum()

void KURL::setFileEncoding const QString &    encoding

Parameters:
encoding  the encoding to add or QString::null to remove the encoding.

void KURL::setFileName const QString &    _txt
 

Sets the filename of the path. 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  The filename to be set. It is considered to be decoded. If the current path ends with '/' then _txt int 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.

Parameters:
_txt  the new name of the host or QString::null to remove the host

void KURL::setHTMLRef const QString &    _ref

_ref  The new reference. This is considered to be not encoded in contrast to setRef(). Use QString::null to remove it.
See also:
htmlRef()

void KURL::setPass const QString &    _txt
 

Sets the password (corresponding to user()) included in the URL.

Special characters in the password will appear encoded in the URL. Note that a password can only appear in a URL string if you also set a user.

Parameters:
_txt  the password to set or QString::null to remove the password
See also:
setUser , hasUser

void KURL::setPath const QString &    path
 

Sets the path of the URL. The query is not changed by this function.

Parameters:
path  The new 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. Can be QString::null to delete the path.

void KURL::setPort unsigned short int    _p
 

Sets the port number included in the URL.

Parameters:
_p  the new port number or 0 to have no port number

void KURL::setProtocol const QString &    _txt
 

Sets the protocol for the URL (i.e., file, http, etc.)

Parameters:
_txt  the new protocol of the URL (without colon)

void KURL::setQuery const QString &    _txt,
int    encoding_hint = 0
 

Parameters:
_txt  This is considered to be encoded. This has a good reason: The query may contain the 0 character.
The query should start with a '?'. If it doesn't '?' is prepended.
Parameters:
encoding_hint  Reserved, should be 0.
See also:
QTextCodec::mibEnum()

void KURL::setRef const QString &    _txt [inline]
 

Sets the reference part (everything after '#').

Parameters:

Definition at line 372 of file kurl.h.

void KURL::setUser const QString &    _txt
 

Sets the user name (login, user id, ...) included in the URL.

Special characters in the user name will appear encoded in the URL.

Parameters:
_txt  the name of the user or QString::null to remove the user

List KURL::split const KURL &    _url [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.htmlref1. 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.

Returns:
An empty list on error or the list of split URLs.
Parameters:
_url  The URL that has to be split.
See also:
hasSubURL

List KURL::split const QString &    _url [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.htmlref1. 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.
See also:
hasSubURL

KURL KURL::upURL  
 

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.

Returns:
a URL that is a level higher

QString KURL::url int    _trailing = 0,
int    encoding_hint = 0
const
 

Returns the URL as string.

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.
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  MIB of encoding to use.
See also:
QTextCodec::mibEnum()

QString KURL::user   const [inline]
 

Returns the decoded user name (login, user id, ...) included in the URL.

Returns:
the user name or QString::null if there is no user name
