## 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. (e.g. '#'->"%23", space->"%20") (In a URL the hash-character '#' is used to specify a "reference", i.e. the position within a document).

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&).

         KURL kurl;
         kurl.setPath("/bar/#foo#");
         QString url = kurl.url();    // -> "file:///bar/%23foo%23"

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.

Instead you should use addPath(): 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"

Note that prettyURL() doesn't change the character escapes (like "%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

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.

## Member Enumeration Documentation

enum KURL::URIMode

Defines the type of URI we are processing.

Enumeration values:

  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.

Definition at line 134 of file kurl.h.

enum KURL::QueryItemsOptions

Options for queryItems.

Currently, only one option is defined:

Parameters:

  | CaseInsensitiveKeys | normalize query keys to lowercase.

Since:
  3.1

## Constructor & Destructor Documentation

KURL::KURL | ( |  | ) |

| Constructs an empty URL. Definition at line 447 of file kurl.cpp. Referenced by fromPathOrURL(), join(), KURL::List::List(), split(), and upURL().

KURL::~KURL | ( |  | ) |

| Destructs the KURL object. Definition at line 452 of file kurl.cpp.

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.

Definition at line 457 of file kurl.cpp.

References url().

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.

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.

Definition at line 514 of file kurl.cpp.

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.

QString KURL::path | ( | int | _trailing | ) | 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. Can be QString::null if no path is set.

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::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.

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).

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.

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:

Returns the URL as string, 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. Please note that the string returned by url() will include the password of the URL. If you want to show the URL to the user, use prettyURL().

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.

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.

KURL::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.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.
