Symfony2创建基于域名的路由(原创翻译)

你可以匹配将要来到的请求以HTTP域名的方式

YAML方式

mobile_homepage:

    path:     /

    host:     m.example.com

    defaults: { _controller: AcmeDemoBundle:Main:mobileHomepage }

homepage:

    path:     /

    defaults: { _controller: AcmeDemoBundle:Main:homepage }

XML方式

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://symfony.com/schema/routing

        http://symfony.com/schema/routing/routing-1.0.xsd">

    <route id="mobile_homepage" path="/" host="m.example.com">

        <default key="_controller">AcmeDemoBundle:Main:mobileHomepage</default>

    </route>

    <route id="homepage" path="/">

        <default key="_controller">AcmeDemoBundle:Main:homepage</default>

    </route>

</routes>

PHP方式

use Symfony\Component\Routing\RouteCollection;

use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

$collection->add('mobile_homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:mobileHomepage',

), array(), array(), 'm.example.com'));

$collection->add('homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:homepage',

)));

return $collection;

两个路由匹配相同的路径 / ,然而第一个将只有域名为m.example.com才匹配

使用占位符

这个域名选项使用占位符的路径匹配系统。这样就意味着你可以在你的域名中使用占位符匹配的域名。

YAML

projects_homepage:

    path:     /

    host:     "{project_name}.example.com"

    defaults: { _controller: AcmeDemoBundle:Main:mobileHomepage }

homepage:

    path:     /

    defaults: { _controller: AcmeDemoBundle:Main:homepage }

XML

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://symfony.com/schema/routing

        http://symfony.com/schema/routing/routing-1.0.xsd">

    <route id="projects_homepage" path="/" host="{project_name}.example.com">

        <default key="_controller">AcmeDemoBundle:Main:mobileHomepage</default>

    </route>

    <route id="homepage" path="/">

        <default key="_controller">AcmeDemoBundle:Main:homepage</default>

    </route>

</routes>

PHP

use Symfony\Component\Routing\RouteCollection;

use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

$collection->add('project_homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:mobileHomepage',

), array(), array(), '{project_name}.example.com'));

$collection->add('homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:homepage',

)));

return $collection;

你还可以为这些占位符设置条件和默认的选项。列如，如果你想匹配 m.example.com 和mobile.example.com你可以按照如下方式

YAML

mobile_homepage:

    path:     /

    host:     "{subdomain}.example.com"

    defaults:

        _controller: AcmeDemoBundle:Main:mobileHomepage

        subdomain: m

    requirements:

        subdomain: m|mobile

homepage:

    path:     /

    defaults: { _controller: AcmeDemoBundle:Main:homepage }

XML

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://symfony.com/schema/routing

        http://symfony.com/schema/routing/routing-1.0.xsd">

    <route id="mobile_homepage" path="/" host="{subdomain}.example.com">

        <default key="_controller">AcmeDemoBundle:Main:mobileHomepage</default>

        <default key="subdomain">m</default>

        <requirement key="subdomain">m|mobile</requirement>

    </route>

    <route id="homepage" path="/">

        <default key="_controller">AcmeDemoBundle:Main:homepage</default>

    </route>

</routes>

PHP

use Symfony\Component\Routing\RouteCollection;

use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

$collection->add('mobile_homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:mobileHomepage',

    'subdomain'   => 'm',

), array(

    'subdomain' => 'm|mobile',

), array(), '{subdomain}.example.com'));

$collection->add('homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:homepage',

)));

return $collection;

你还可以使用服务参数，如果你不想将域名写死写法如下

YAML

mobile_homepage:

    path:     /

    host:     "m.{domain}"

    defaults:

        _controller: AcmeDemoBundle:Main:mobileHomepage

        domain: '%domain%'

    requirements:

        domain: '%domain%'

homepage:

    path:  /

    defaults: { _controller: AcmeDemoBundle:Main:homepage }

XML

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://symfony.com/schema/routing http://symfony.com/schema/routing/routing-1.0.xsd">

    <route id="mobile_homepage" path="/" host="m.{domain}">

        <default key="_controller">AcmeDemoBundle:Main:mobileHomepage</default>

        <default key="domain">%domain%</default>

        <requirement key="domain">%domain%</requirement>

    </route>

    <route id="homepage" path="/">

        <default key="_controller">AcmeDemoBundle:Main:homepage</default>

    </route>

</routes>

PHP

use Symfony\Component\Routing\RouteCollection;

use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

$collection->add('mobile_homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:mobileHomepage',

    'domain' => '%domain%',

), array(

    'domain' => '%domain%',

), array(), 'm.{domain}'));

$collection->add('homepage', new Route('/', array(

    '_controller' => 'AcmeDemoBundle:Main:homepage',

)));

return $collection;

提示

确保你总是包含了默认的选项 domain占位符，否则你需要包含 domain的值每当你使用该路由生成URL的时候。

使用包含进来的路由规则匹配

你可以设置域名选项通过导入路由配置文件，方式如下

YAML

acme_hello:

    resource: '@AcmeHelloBundle/Resources/config/routing.yml'

    host:     "hello.example.com"

XML

<?xml version="1.0" encoding="UTF-8" ?>

<routes xmlns="http://symfony.com/schema/routing"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://symfony.com/schema/routing http://symfony.com/schema/routing/routing-1.0.xsd">

    <import resource="@AcmeHelloBundle/Resources/config/routing.xml" host="hello.example.com" />

</routes>

PHP

use Symfony\Component\Routing\RouteCollection;

$collection = new RouteCollection();

$collection->addCollection($loader->import("@AcmeHelloBundle/Resources/config/routing.php"), '', array(), array(), array(), 'hello.example.com');

return $collection;

域名 hello.example.com 将要被设置为加载进来的新路由配置文件中的每个路由

测试你的Controllers

你需要设置HTTP的域名头文件在你请求的对象中，如果你想正确的匹配到网址在你的测试函数中

$crawler = $client->request(

    'GET',

    '/homepage',

    array(),

    array(),

    array('HTTP_HOST' => 'm.' . $client->getContainer()->getParameter('domain'))

);
