Question

应用程序/配置/ routing.php

这是应该如何做的

$collection = new RouteCollection();

$collection->addCollection(
// second argument is the type, which is required to enable
// the annotation reader for this resource
    $loader->import("@AppBundle/Controller/", "annotation")
);

return $this->collection;

我需要为公司创建一个更复杂的路由系统，并且需要能够在班级中注册路线。

class AutoRouter extends AppKernel
{ 
    function __construct()
    {

    }

    public function registerControllers()
    {
        $collection = new RouteCollection();
        global $loader;
        $collection->addCollection(
            // second argument is the type, which is required to enable
            // the annotation reader for this resource
            $loader->import("@AppBundle/Controller/", "annotation")
        );

        return $this->collection;
    }
    //(....)
}

tldr;我需要从registerControllers方法访问import函数，但它会抛出此错误

    use Symfony\Component\Routing\RouteCollection;

    class AutoRouter extends AppKernel
    {
        private $collection;

        public function registerControllers($loader)
        {
            $collection = new RouteCollection();
            $collection->addCollection(
                // second argument is the type, which is required to enable
                // the annotation reader for this resource
                $loader->import("@AppBundle/Controller/", "annotation")
            );

            return $this->collection;
        }

        public function getActiveBundles()
        {
            return $this->registerBundles();
        }

    }

    $at = new AutoRouter('dev', true);
    return $at->registerControllers($loader);

这是利用dependency injection的绝佳机会。您应该将public IQueryable<User> GetAll() { const string query = @" select * from [dbo].[User] "; return this._db.Query<User>(query, new {}).AsQueryable(); }实例作为类型提示参数注入，以确保提供正确的对象实例。

$loader

使用依赖注入还可以更容易地在将来更改具体实现，而无需更改“消费”。代码。

快乐的编码！

如何从类中访问$ loader变量？
