从silex中的服务提供者获取调用类/方法

If I had the following code how would I get the calling method and the class in the provider:

class HelloServiceProvider implements ServiceProviderInterface {
    public function register(Application $app){
        $app['hello'] = $app->share(function () {
            // Get hello/indexAction
        });
    }

    public function boot(Application $app){}
}

class hello {
    public function addAction(){
        $app['hello']()
    }
}


$app->get('/hello', 'hello.controller:indexAction');

Is this even possible? Thanks

Is it, indeed, possible but you need some changes:

<?php

// file HelloServiceProvider.php
class HelloServiceProvider implements ServiceProviderInterface {
    public function register(Application $app){
        $app['hello'] = $app->share(function () {
            // Get hello/indexAction
        });
    }

    public function boot(Application $app){}
}

// file Hello.php
class Hello {
    public function indexAction(Application $app){
        $app['hello']()
    }
}

// somewhere in your code:
$app->register(new Silex\Provider\ServiceControllerServiceProvider());
$app->register(new HelloServiceProvider());

$app['hello.controller'] = $app->share(function() {
    return new hello();
});

$app->get('/hello', 'hello.controller:indexAction');

Notice that the use statements are missing from code

You can get more information in the official documentation.
