How to Match a Route Based on the Host¶
2.2 新版功能: Host matching support was introduced in Symfony 2.2
You can also match on the HTTP host of the incoming request.
- YAML
mobile_homepage: path: / host: m.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="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
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;
Both routes match the same path /, however the first one will match only if the host is m.example.com.
Using Placeholders¶
The host option uses the same syntax as the path matching system. This means you can use placeholders in your hostname:
- 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;
You can also set requirements and default options for these placeholders. For instance, if you want to match both m.example.com and mobile.example.com, you use this:
- 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;
小技巧
You can also use service parameters if you do not want to hardcode the hostname:
- 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;
小技巧
Make sure you also include a default option for the domain placeholder, otherwise you need to include a domain value each time you generate a URL using the route.
Using Host Matching of Imported Routes¶
You can also set the host option on imported routes:
- 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;
The host hello.example.com will be set on each route loaded from the new routing resource.
Testing your Controllers¶
You need to set the Host HTTP header on your request objects if you want to get past url matching in your functional tests.
$crawler = $client->request(
'GET',
'/homepage',
array(),
array(),
array('HTTP_HOST' => 'm.' . $client->getContainer()->getParameter('domain'))
);
