KURL Class Reference
#include <kurl.h>
Detailed Description
Represents and parses a URL.A prototypical URL looks like:
protocol://user:password@hostname:port/path/to/file.ext#reference
KURL handles escaping of URLs. This means that the specification of a full URL will differ from the corresponding string that would specify a local file or directory in file-operations like fopen. This is because an URL doesn't allow certain characters and escapes them.
For examle:
- '#' -> "%23" (In a URL the hash-character
'#'is used to specify a "reference", i.e. the position within a document) - space -> "%20"
The constructor KURL(const QString&) expects a string properly escaped, or at least non-ambiguous. For instance a local file or directory "/bar/#foo#" would have the URL "file:///bar/%23foo%23". If you have the absolute path and need the URL-escaping you should create KURL via the default-constructor and then call setPath(const QString&):
If you have the URL of a local file or directory and need the absolute path, you would use path().
KURL url( "file:///bar/%23foo%23" ); ... if ( url.isLocalFile() ) QString path = url.path(); // -> "/bar/#foo#"
The other way round: if the user can enter a string, that can be either a path or a URL, then you need to use KURL::fromPathOrURL() to build a KURL.
This must also be considered, when you have separated directory and file strings and need to put them together. While you can simply concatenate normal path strings, you must take care if the directory-part is already an escaped URL. (This might be needed if the user specifies a relative path, and your program supplies the rest from elsewhere.)
Wrong:
QString dirUrl = "file:///bar/"; QString fileName = "#foo#"; QString invalidURL = dirUrl + fileName; // -> "file:///bar/#foo#" won't behave like you would expect.
Right:
KURL url( "file:///bar/" ); QString fileName = "#foo#"; url.addPath( fileName ); QString validURL = url.url(); // -> "file:///bar/%23foo%23"
Also consider that some URLs contain the password, but this shouldn't be visible. Your program should use prettyURL() every time it displays a URL, whether in the GUI or in debug output or...
KURL url( "ftp://name:password@ftp.faraway.org/bar/%23foo%23"); QString visibleURL = url.prettyURL(); // -> "ftp://name@ftp.faraway.org/bar/%23foo%23"
"%23"). Otherwise the URL would be invalid and the user wouldn't be able to use it in another context.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
"/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.

Member Enumeration Documentation
Flags to choose how file: URLs are treated when creating their QString representation with prettyURL(int,AdjustementFlags).
However it is recommended to use pathOrURL() instead of this variant of prettyURL()
| enum KURL::URIMode |
Defines the type of URI we are processing.
- Enumerator:
-
Auto Automatically detected. Using this mode, an appropriate processing mode will be selected when the URI is first processed.
Invalid Invalid URI. This is something that can't be parsed as a URI at all. The contents are accessible through the protocol() method.
RawURI Raw URI. This type of URI should not be processed in any way. Contents are accessible through the path() method.
URL Standards compliant URL. Process as a syntactically correct URL.
Mailto Mailto URI. path() contains an email address which should have its domain part processed as a DNS name. The email address is accessible through the path() method.
Constructor & Destructor Documentation
| KURL::KURL | ( | ) |
| KURL::KURL | ( | const QString & | url, | |
| int | encoding_hint = 0 | |||
| ) |
Usual constructor, to construct from a string.
- Warning:
- It is dangerous to feed UNIX filenames into this function, this will work most of the time but not always.
"/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 use fromPathOrURL()
- Parameters:
-
url a URL, not a filename. If the URL does not have a protocol part, "file:"is assumedencoding_hint MIB of original encoding of URL. See QTextCodec::mibEnum()
- See also:
- fromPathOrURL()
| KURL::KURL | ( | const char * | url, | |
| int | encoding_hint = 0 | |||
| ) |
Constructor taking an URL encoded in a C string.
Constructor taking a char * url, which is an encoded representation of the URL, exactly like the usual constructor. This is useful when the URL, in its encoded form, is strictly ASCII.
- Warning:
- It is dangerous to feed UNIX filenames into this function, this will work most of the time but not always.
"/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 use fromPathOrURL()
- Parameters:
-
url an encoded URL. If the URL does not have a protocol part, "file:"is assumedencoding_hint MIB of original encoding of URL. See QTextCodec::mibEnum()
- See also:
- fromPathOrURL()
| KURL::KURL | ( | const QCString & | url, | |
| int | encoding_hint = 0 | |||
| ) |
Constructor taking an URL encoded in a QCString.
Constructor taking a QCString url, which is an encoded representation of the URL, exactly like the usual constructor. This is useful when the URL, in its encoded form, is strictly ASCII.
- Warning:
- It is dangerous to feed UNIX filenames into this function, this will work most of the time but not always.
"/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 use fromPathOrURL()
- Parameters:
-
url A encoded URL. If the URL does not have a protocol part, "file:"is assumedencoding_hint MIB of original encoding of URL. See QTextCodec::mibEnum()
- See also:
- fromPathOrURL()
| KURL::KURL | ( | const KURL & | u | ) |
| KURL::KURL | ( | const QUrl & | u | ) |
Constructor allowing relative URLs.
- Warning:
- It is dangerous to feed UNIX filenames into this function, this will work most of the time but not always.
"/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 use fromPathOrURL()
- Parameters:
-
_baseurl The base url. _rel_url A relative or absolute URL. If this is an absolute URL then _baseurlwill be ignored. If this is a relative URL it will be combined with_baseurl. Note that_rel_urlshould be encoded too, in any case. So do NOT pass a path here (use setPath() or addPath() or fromPathOrURL() instead)encoding_hint MIB of original encoding of URL.

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
Adds 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 QTextCodec::mibEnum()
- See also:
- queryItem()
| void KURL::adjustPath | ( | int | _trailing | ) |
Adds or removes a trailing slash to/from the path.
The _trailing parameter allows to ensure the existance or absence of the last (trailing) '/' character in the path. If the URL has no path, then no '/' is added anyway. And on the other side: if the path is just "/", 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.
- Parameters:
-
_trailing May be ( -1,0,+1).-1strips a trailing'/',+1adds a trailing'/'if there is none yet and0returns the path unchanged
- See also:
- hasPath()
| 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:
trueif successful
- See also:
- directory()
| 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, occurrences of consecutive directory separators (e.g."/foo//bar") are cleaned up as well
- See also:
- hasPath()
| bool KURL::cmp | ( | const KURL & | u, | |
| bool | ignore_trailing = false | |||
| ) | const |
Compares this URL with another one.
The same as equals(), just with a less obvious name.
- Parameters:
-
u the URL to compare this one with ignore_trailing set to trueto ignore trailing'/'characters
- Returns:
trueif both URLs are the same
- See also:
- operator==. This function should be used if you want to ignore trailing
'/'characters
- Deprecated:
- Use equals() instead.
Decodes a string as used in URLs.
Convenience function.
Decode -style encoding and convert from local encoding to unicode.
Reverse of encode_string()
- Parameters:
-
str the string to decode (can be QString::null)encoding_hint MIB of original encoding of str. See QTextCodec::mibEnum()
- Returns:
- the decoded string
- See also:
- encode_string()
| QString KURL::directory | ( | bool | _strip_trailing_slash_from_result = true, |
|
| bool | _ignore_trailing_slash_in_path = true | |||
| ) | const |
Returns the directory of the path.
The directory is 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/".
_ignore_trailing_slash_in_path tells whether a trailing '/' should be ignored. This means that the function would return "/hallo" (or "/hallo" depending on _strip_trailing_slash_from_result) for "file:///hallo/torben/" and "file:///hallo/torben".
- 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 if set to false, then everything behind the last'/'is considered to be the filename
- Returns:
- the directory part of the current path or
QString::nullwhen there is no path. The returned string is decoded
- See also:
- setDirectory()
Encodes a string for use in URLs.
Convenience function.
Convert unicoded string to local encoding and use %-style encoding for all common delimiters / non-ascii characters.
- Parameters:
-
str the string to encode (can be QString::null)encoding_hint MIB of encoding to use. See QTextCodec::mibEnum()
- Returns:
- the encoded string
- See also:
- encode_string_no_slash()
Encodes a string for use in URLs.
Convenience function.
Convert unicoded string to local encoding and use %-style encoding for all common delimiters and non-ascii characters as well as the slash '/'.
- Parameters:
-
str the string to encode (can be QString::null)encoding_hint MIB of encoding to use. See QTextCodec::mibEnum()
- See also:
- encode_string()
| QString KURL::encodedHtmlRef | ( | ) | const |

| QString KURL::encodedPathAndQuery | ( | int | _trailing = 0, |
|
| bool | _no_empty_path = false, |
|||
| int | encoding_hint = 0 | |||
| ) | const |
Returns the encoded path and the query.
The _trailing parameter allows to ensure the existance or absence of the last (trailing) '/' character in the path. If the URL has no path, then no '/' is added anyway. And on the other side: if the path is just "/", 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.
- Parameters:
-
_trailing May be ( -1,0,+1).-1strips a trailing'/',+1adds a trailing'/'if there is none yet and0returns the path unchanged_no_empty_path if set to truethen an empty path is substituted by"/"encoding_hint MIB of desired encoding of URL. See QTextCodec::mibEnum()
