# 生成 URL 和 路径（Generating URLs and Paths）[](# "永久链接至标题") [*Phalcon\Mvc\Url*](#) is the component responsible of generate URLs in a Phalcon application. It'scapable of produce independent URLs based on routes. [*Phalcon\Mvc\Url*](#) 组件负责在Phalcon应用内生成URL。它依赖路由生成独立的URL。 ### 设置站点基地址（Setting a base URI）[](# "永久链接至标题") Depending of which directory of your document root your application is installed, it may have a base URI or not. For example, if your document root is /var/www/htdocs and your application is installed in /var/www/htdocs/invo then yourbaseUri will be /invo/. If you are using a VirtualHost or your application is installed on the document root, then your baseUri is /.Execute the following code to know the base URI detected by Phalcon: ~~~ <?php use Phalcon\Mvc\Url; $url = new Url(); echo $url->getBaseUri(); ~~~ By default, Phalcon automatically may detect your baseUri, but if you want to increase the performance of your applicationis recommended setting up it manually: ~~~ <?php use Phalcon\Mvc\Url; $url = new Url(); // Setting a relative base URI $url->setBaseUri('/invo/'); // Setting a full domain as base URI $url->setBaseUri('//my.domain.com/'); // Setting a full domain as base URI $url->setBaseUri('http://my.domain.com/my-app/'); ~~~ Usually, this component must be registered in the Dependency Injector container, so you can set up it there: ~~~ <?php use Phalcon\Mvc\Url; $di->set('url', function () { $url = new Url(); $url->setBaseUri('/invo/'); return $url; }); ~~~ ### 生成 URI（Generating URIs）[](# "永久链接至标题") If you are using the [*Router*](#) with its default behavior. Your application is able to match routes based on thefollowing pattern: /:controller/:action/:params. Accordingly it is easy to create routes that satisfy that pattern (or any otherpattern defined in the router) passing a string to the method “get”: ~~~ <?php echo $url->get("products/save"); ?> ~~~ Note that isn't necessary to prepend the base URI. If you have named routes you can easily change it creating it dynamically.For Example if you have the following route: ~~~ <?php $route->add( "/blog/{year}/{month}/{title}", array( 'controller' => 'posts', 'action' => 'show' ) )->setName('show-post'); ~~~ A URL can be generated in the following way: ~~~ <?php // This produces: /blog/2015/01/some-blog-post $url->get( array( 'for' => 'show-post', 'year' => 2015, 'month' => '01', 'title' => 'some-blog-post' ) ); ~~~ ### 没有伪静态状态下的生成 URL（Producing URLs without Mod-Rewrite）[](# "永久链接至标题") You can use this component also to create URLs without mod-rewrite: ~~~ <?php use Phalcon\Mvc\Url; $url = new Url(); // Pass the URI in $_GET["_url"] $url->setBaseUri('/invo/index.php?_url=/'); // This produce: /invo/index.php?_url=/products/save echo $url->get("products/save"); ~~~ You can also use $_SERVER[“REQUEST_URI”]: ~~~ <?php use Phalcon\Mvc\Url; $url = new Url(); // Pass the URI in $_GET["_url"] $url->setBaseUri('/invo/index.php?_url=/'); // Pass the URI using $_SERVER["REQUEST_URI"] $url->setBaseUri('/invo/index.php/'); ~~~ In this case, it's necessary to manually handle the required URI in the Router: ~~~ <?php use Phalcon\Mvc\Router; $router = new Router(); // ... Define routes $uri = str_replace($_SERVER["SCRIPT_NAME"], '', $_SERVER["REQUEST_URI"]); $router->handle($uri); ~~~ The produced routes would look like: ~~~ <?php // This produce: /invo/index.php/products/save echo $url->get("products/save"); ~~~ ### Volt 中生成 URL（Volt Producing URLs from Volt）[](# "永久链接至标题") The function “url” is available in volt to generate URLs using this component: ~~~ <a href="{{ url("posts/edit/1002") }}">Edit</a> ~~~ Generate static routes: ~~~ <link rel="stylesheet" href="{{ static_url("css/style.css") }}" type="text/css" /> ~~~ ### 静态 URI 与 动态 URI（Static vs. Dynamic URIs）[](# "永久链接至标题") This component allow you to set up a different base URI for static resources in the application: ~~~ <?php use Phalcon\Mvc\Url; $url = new Url(); // Dynamic URIs are $url->setBaseUri('/'); // Static resources go through a CDN $url->setStaticBaseUri('http://static.mywebsite.com/'); ~~~ [*Phalcon\Tag*](#) will request both dynamical and static URIs using this component. ### 自定义 URL 生成器（Implementing your own URL Generator）[](# "永久链接至标题") The [*Phalcon\Mvc\UrlInterface*](#) interface must be implemented to create your own URLgenerator replacing the one provided by Phalcon. | - [索引](# "总目录") - [下一页](# "闪存消息（Flashing Messages）") | - [上一页](# "Cookie 管理（Cookies Management）") |
