/**
|
||
|
|
* CUrlManager manages the URLs of Yii Web applications.
|
||
|
|
*
|
||
|
|
* It provides URL construction ({@link createUrl()}) as well as parsing ({@link parseUrl()}) functionality.
|
||
|
|
*
|
||
|
|
* URLs managed via CUrlManager can be in one of the following two formats,
|
||
|
|
* by setting {@link setUrlFormat urlFormat} property:
|
||
|
|
* <ul>
|
||
|
|
* <li>'path' format: /path/to/EntryScript.php/name1/value1/name2/value2...</li>
|
||
|
|
* <li>'get' format: /path/to/EntryScript.php?name1=value1&name2=value2...</li>
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* When using 'path' format, CUrlManager uses a set of {@link setRules rules} to:
|
||
|
|
* <ul>
|
||
|
|
* <li>parse the requested URL into a route ('ControllerID/ActionID') and GET parameters;</li>
|
||
|
|
* <li>create URLs based on the given route and GET parameters.</li>
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* A rule consists of a route and a pattern. The latter is used by CUrlManager to determine
|
||
|
|
* which rule is used for parsing/creating URLs. A pattern is meant to match the path info
|
||
|
|
* part of a URL. It may contain named parameters using the syntax '<ParamName:RegExp>'.
|
||
|
|
*
|
||
|
|
* When parsing a URL, a matching rule will extract the named parameters from the path info
|
||
|
|
* and put them into the $_GET variable; when creating a URL, a matching rule will extract
|
||
|
|
* the named parameters from $_GET and put them into the path info part of the created URL.
|
||
|
|
*
|
||
|
|
* If a pattern ends with '/*', it means additional GET parameters may be appended to the path
|
||
|
|
* info part of the URL; otherwise, the GET parameters can only appear in the query string part.
|
||
|
|
*
|
||
|
|
* To specify URL rules, set the {@link setRules rules} property as an array of rules (pattern=>route).
|
||
|
|
* For example,
|
||
|
|
* <pre>
|
||
|
|
* array(
|
||
|
|
* 'articles'=>'article/list',
|
||
|
|
* 'article/<id:\d+>/*'=>'article/read',
|
||
|
|
* )
|
||
|
|
* </pre>
|
||
|
|
* Two rules are specified in the above:
|
||
|
|
* <ul>
|
||
|
|
* <li>The first rule says that if the user requests the URL '/path/to/index.php/articles',
|
||
|
|
* it should be treated as '/path/to/index.php/article/list'; and vice versa applies
|
||
|
|
* when constructing such a URL.</li>
|
||
|
|
* <li>The second rule contains a named parameter 'id' which is specified using
|
||
|
|
* the <ParamName:RegExp> syntax. It says that if the user requests the URL
|
||
|
|
* '/path/to/index.php/article/13', it should be treated as '/path/to/index.php/article/read?id=13';
|
||
|
|
* and vice versa applies when constructing such a URL.</li>
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* The route part may contain references to named parameters defined in the pattern part.
|
||
|
|
* This allows a rule to be applied to different routes based on matching criteria.
|
||
|
|
* For example,
|
||
|
|
* <pre>
|
||
|
|
* array(
|
||
|
|
* '<_c:(post|comment)>/<id:\d+>/<_a:(create|update|delete)>'=>'<_c>/<_a>',
|
||
|
|
* '<_c:(post|comment)>/<id:\d+>'=>'<_c>/view',
|
||
|
|
* '<_c:(post|comment)>s/*'=>'<_c>/list',
|
||
|
|
* )
|
||
|
|
* </pre>
|
||
|
|
* In the above, we use two named parameters '<_c>' and '<_a>' in the route part. The '<_c>'
|
||
|
|
* parameter matches either 'post' or 'comment', while the '<_a>' parameter matches an action ID.
|
||
|
|
*
|
||
|
|
* Like normal rules, these rules can be used for both parsing and creating URLs.
|
||
|
|
* For example, using the rules above, the URL '/index.php/post/123/create'
|
||
|
|
* would be parsed as the route 'post/create' with GET parameter 'id' being 123.
|
||
|
|
* And given the route 'post/list' and GET parameter 'page' being 2, we should get a URL
|
||
|
|
* '/index.php/posts/page/2'.
|
||
|
|
*
|
||
|
|
* It is also possible to include hostname into the rules for parsing and creating URLs.
|
||
|
|
* One may extract part of the hostname to be a GET parameter.
|
||
|
|
* For example, the URL <code>http://admin.example.com/en/profile</code> may be parsed into GET parameters
|
||
|
|
* <code>user=admin</code> and <code>lang=en</code>. On the other hand, rules with hostname may also be used to
|
||
|
|
* create URLs with parameterized hostnames.
|
||
|
|
*
|
||
|
|
* In order to use parameterized hostnames, simply declare URL rules with host info, e.g.:
|
||
|
|
* <pre>
|
||
|
|
* array(
|
||
|
|
* 'http://<user:\w+>.example.com/<lang:\w+>/profile' => 'user/profile',
|
||
|
|
* )
|
||
|
|
* </pre>
|
||
|
|
*
|
||
|
|
* Starting from version 1.1.8, one can write custom URL rule classes and use them for one or several URL rules.
|
||
|
|
* For example,
|
||
|
|
* <pre>
|
||
|
|
* array(
|
||
|
|
* // a standard rule
|
||
|
|
* '<action:(login|logout)>' => 'site/<action>',
|
||
|
|
* // a custom rule using data in DB
|
||
|
|
* array(
|
||
|
|
* 'class' => 'application.components.MyUrlRule',
|
||
|
|
* 'connectionID' => 'db',
|
||
|
|
* ),
|
||
|
|
* )
|
||
|
|
* </pre>
|
||
|
|
* Please note that the custom URL rule class should extend from {@link CBaseUrlRule} and
|
||
|
|
* implement the following two methods,
|
||
|
|
* <ul>
|
||
|
|
* <li>{@link CBaseUrlRule::createUrl()}</li>
|
||
|
|
* <li>{@link CBaseUrlRule::parseUrl()}</li>
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* CUrlManager is a default application component that may be accessed via
|
||
|
|
* {@link CWebApplication::getUrlManager()}.
|
||
|
|
*
|
||
|
|
* @property string $baseUrl The base URL of the application (the part after host name and before query string).
|
||
|
|
* If {@link showScriptName} is true, it will include the script name part.
|
||
|
|
* Otherwise, it will not, and the ending slashes are stripped off.
|
||
|
|
* @property string $urlFormat The URL format. Defaults to 'path'. Valid values include 'path' and 'get'.
|
||
|
|
* Please refer to the guide for more details about the difference between these two formats.
