嗨，我从一个自己编写的路由引擎切换到了hpleague路由。我的问题是：我可以访问路由操作方法之外的通配符变量吗？
示例
路由部分：
$router = new League'Route'RouteCollection;
$router->addRoute('GET', '{locale}/{controller}/{action}', ''Backend'Controller'{controller}Controller::{action}');
$dispatcher = $router->getDispatcher();
//making a call with, for example, '/en/foo/bar', or '/de/foo/bar'
$response = $dispatcher->dispatch($oRequest->getMethod(), $oRequest->getPathInfo());
$response->send();
控制器部分
class FooController extends AppController {
public function __construct() {
//<---- here i want to access the {locale} from the URI somehow
}
public function bar(Request $request, Response $response, array $args) {
// $args = [
// 'locale' => 'de', // the actual value of {locale}
// 'controller' => 'foo' // the actual value of {controller}
// 'action' => 'bar' // the actual value of {bar}
// ];
}
}
我在文件中找不到任何东西
我使用的是"联赛/路线"："^1.2"
我认为默认情况下，您只能静态调用控制器类中的方法，并且当您这样做时，不会自动调用控制器的构造函数。此外，您也不能使用路由的通配符来动态调用控制器。
请注意，这是不安全的，但您仍然可以使用联盟/路线中的自定义策略执行您想要的操作，如下所示：
控制器
class TestController {
public function __construct($args) {
//the wildcards will be passed as an array in the constructor like this
$this->locale = $args['locale'];
}
public function check(Request $request, Response $response, array $args) {
// $args = [
// 'locale' => 'de', // the actual value of {locale}
// 'controller' => 'Test' // the actual value of {controller}
// 'action' => 'check' // the actual value of {action}
// ];
return $response;
}
}
自定义策略
class CustomStrategy implements StrategyInterface {
public function dispatch($controller, array $vars)
{
$controller_parts = [];
foreach($controller as $con){
foreach ($vars as $key => $value) {
$placeholder = sprintf('{%s}', $key);
$con = str_replace($placeholder, $value, $con);
}
$controller_parts[] = $con;
}
//the controller will be instantiated inside the strategy
$controllerObject = new $controller_parts[0]($vars);
//and the action will be called here
return $controllerObject->$controller_parts[1](Request::createFromGlobals(),new Response(),$vars);
}
}
具有自定义策略集成的路由
$router = new League'Route'RouteCollection;
$router->setStrategy(new CustomStrategy()); //integrate the custom strategy
$router->addRoute('GET', '/{locale}/{controller}/{action}', '{controller}Controller::{action}');
$dispatcher = $router->getDispatcher();
//if your url is /en/Test/check, then TestController->check() will be called
$response = $dispatcher->dispatch($oRequest->getMethod(), $oRequest->getPathInfo());
$response->send();
