Question

有人可以向我解释一下在silverstripe 4中行为是如何运作的吗？

我有这样的控制器：

<?php

use SilverStripe\Control\HTTPRequest;

class ShopHolderPageController extends PageController
{
    private static $allowed_actions = [
        'add-shop'
    ];

    private static $url_handlers = [
        'add-shop' => 'shopForm'
    ];

    protected function init()
    {
        parent::init();
    }

    public function shopForm(HTTPRequest $request)
    {
        return 'test';
    }
}

当我在浏览器中启动它时，我得到了这个：

Debug (line 261 of RequestHandler.php): Testing 'add-shop' with 'add-shop' on ShopHolderPageController

Debug (line 271 of RequestHandler.php): Rule 'add-shop' matched to action 'shopForm' on ShopHolderPageController. Latest request params: array ( )

Debug (line 261 of RequestHandler.php): Testing '$Action//$ID/$OtherID' with '' on SilverStripe\ErrorPage\ErrorPageController

Debug (line 271 of RequestHandler.php): Rule '$Action//$ID/$OtherID' matched to action 'handleAction' on SilverStripe\ErrorPage\ErrorPageController. Latest request params: array ( 'Action' => NULL, 'ID' => NULL, 'OtherID' => NULL, )

Debug (line 185 of RequestHandler.php): Action not set; using default action method name 'index'

Debug (line 234 of Controller.php): Request handler returned HTTPResponse object to ShopHolderPageController controller;returning it without modification.

我不明白为什么在RequestHandler匹配规则'add-shop'与'shopForm'控制器没有执行'shopForm'动作之后。它不是执行find动作，而是调用errorPageController ...

看起来像：

$ url_handlers更像是动作的别名，而且
行动，即使它有别名＆＃39;在$ url_handlers中总是需要添加到$ allowed_actions

我认为它的作用如下：＆＃39;别名＆＃39;对于该操作应该添加到$ allowed_actions然后它应该在$ url_handlers中映射到action方法

但它的作用如下：＆＃39;别名＆＃39;对于动作应该在$ url_handlers中映射到action方法，然后将action方法添加到$ allowed_actions

所以基本上代码：

use SilverStripe\Control\HTTPRequest;

class ShopHolderPageController extends PageController
{
    private static $allowed_actions = [
        'shopForm'
    ];

    private static $url_handlers = [
        'add-shop' => 'shopForm',
        'edit-shop/$ID' => 'shopForm'
    ];

    protected function init()
    {
        parent::init();
    }

    public function shopForm(HTTPRequest $request)
    {
        var_dump($request->param('ID'));
        return 'test';
    }
}

我们有：对于localhost / shops / add-shop？debug_request = 1

Debug (line 261 of RequestHandler.php): Testing 'add-shop' with 'add-shop' on ShopHolderPageController

Debug (line 271 of RequestHandler.php): Rule 'add-shop' matched to action 'shopForm' on ShopHolderPageController. Latest request params: array ( )

NULL test

和localhost / shops / edit-shop / 12？debug_request = 1

Debug (line 261 of RequestHandler.php): Testing 'add-shop' with 'edit-shop/12' on ShopHolderPageController

Debug (line 261 of RequestHandler.php): Testing 'edit-shop/$ID' with 'edit-shop/12' on ShopHolderPageController

Debug (line 271 of RequestHandler.php): Rule 'edit-shop/$ID' matched to action 'shopForm' on ShopHolderPageController. Latest request params: array ( 'ID' => '12', )

string(2) "12" test

如何在silverstripe 4中的控制器中运行？
