扩展Symfony2控制器解析器 [英] Extending Symfony2 Controller Resolver

问题描述

我当前正在创建一个包，如果请求是Ajax请求，则该包可以将fooAction重命名为fooAjaxAction. 正如那个问题的答案所说，我必须扩展控制器解析器类. 如果更改config.yml中的controller_resolver.class，我将得到一个ResourceNotFoundException.但是如果没有，我不会有任何错误(但是没有覆盖，所以这不是我想要的)

I am currently creating a bundle which can rename fooAction into fooAjaxAction if request is an Ajax Request. As the answer of that question says, I have to extend the controller resolver class. I have a ResourceNotFoundException if I change the controller_resolver.class in config.yml . but if I don't, I don't have any errors (but there is no override so this is not what I want)

我的问题是:如何注册并使用新的控制器解析器?我是正确的 ?错误吗?

这就是我所做的:

您可以在packagist中找到要测试的捆绑软件，并通过以下方式下载:

composer require "/prefix-bundle":"dev-dev"

在AppKernel.php中激活它:

<?php 
// AppKernel.php
new \PrefixBundle\PrefixBundle()

配置

# App/Config/config.yml
parameters:
    controller_resolver.class: PrefixBundle\Component\Controller\ControllerResolver

这是我的自定义控制器.

So this is my custom Controller.

<?php 
namespace \PrefixBundle\Component\Controller;

use Symfony\Component\HttpKernel\ControllerControllerResolver as BaseControllerResolver;
use Symfony\Component\HttpFoundation\Request;

class ControllerResolver extends BaseControllerResolver
{

    public function getArguments(Request $request, $controller)
    {
        parent::getArguments($request, $controller);
    }
}

我假设这个控制器什么也不做，将来我会添加逻辑.

I am assuming that this controller is doing nothing for instance, I will add logic in the future.

推荐答案

getArguments方法缺少返回值(由于在执行其他回答时丢失了返回值)，这意味着控制器解析器实际上并没有得到任何要解决的论点.

The return is missing from the getArguments method (due to me missing it when I did the other answer) meaning that the controller resolver isn't actually getting any arguments to resolve.

public function getArguments(Request $request, $controller)
{
    // Should have the return..
    return parent::getArguments($request, $controller);
}
