Sylius：附加结帐步骤缺少侦听器

Question

我想在 sylius 结帐流程中添加一个结帐步骤。它的工作原理是，当我在购物车概览中并单击结帐时，会显示我添加的步骤。但是，当我单击“下一步”时，出现错误“无法为命名路由“sylius_order_index”生成 URL，因为这样的路由不存在。”

到目前为止我做了什么（现在为了避免分心，我将结帐步骤称为“测试”）：

config/packages/_sylius.yaml:

winzou_state_machine:
    sylius_order_checkout:
        states:
            test_selected: ~ 
        transitions:     
            select_test:
                from: [cart, test_selected, addressed, shipping_selected, shipping_skipped, payment_selected, payment_skipped]
                to: test_selected
            address:
                from: [cart, test_selected, addressed, shipping_selected, shipping_skipped, payment_selected, payment_skipped]
                to: addressed
            select_shipping:
                from: [addressed, test_selected, shipping_selected, payment_selected, payment_skipped]
                to: shipping_selected
            select_payment:
                from: [payment_selected, test_selected, shipping_skipped, shipping_selected]
                to: payment_selected           
        callbacks:
            after:
                sylius_process_cart:
                    on: ["select_shipping", "address", "select_payment", "skip_shipping", "skip_payment", "select_test"]
                    do: ["@sylius.order_processing.order_processor", "process"]
                    args: ["object"]

sylius_shop:
    product_grid:
        include_all_descendants: true
    checkout_resolver:
        route_map:
            cart:
                route: sylius_shop_checkout_test
            test_selected:
                route: sylius_shop_checkout_address

routes/Checkout/checkout.yml:

sylius_shop_checkout_start:
    path: /
    methods: [GET]
    defaults:
        _controller: FrameworkBundle:Redirect:redirect
        route: sylius_shop_checkout_test

sylius_shop_checkout_test:
    path: /test
    methods: [GET, PUT]
    defaults:
        _controller: sylius.controller.order:updateAction
        _sylius:
            event: test
            flash: false
            template: "Checkout/Test/test.html.twig"
            form:
                type: App\Form\TestType
            repository:
                method: findCartForAddressing
                arguments:
                    - "expr:service('sylius.context.cart').getCart().getId()"
            state_machine:
                graph: sylius_order_checkout
                transition: select_test
#after this all other states as they are in native Sylius in this file. The original checkout.yml is completely overridden with this one.

我在 MY 中遵循了编译器而不是 NATIVE 检出步骤，不同之处在于

Bundle/Controller/ResourceController.php 第 311 行：

    $postEventResponse = $postEvent->getResponse();
    if (null !== $postEventResponse) {
        return $postEventResponse;
    }

Response 对象为空（因此 if 未进入，编译器继续生成上述 arbirary/misleading 错误消息）。所以我注意到发生这种情况是因为

symfony/event-dispatcher/EventDispatcher.php 第 72 行：

if ($listeners) {
    $this->callListeners($listeners, $eventName, $event);
}

$listeners 在我的例子中是一个空数组，而对于每个其他本地 sylius 步骤，这里至少有 1 个侦听器订阅。我只是不知道在哪里添加它。谁能告诉我 where/how 已经完成了？

Answer 1

我自己解决了。 services.yaml 中缺少的所有内容如下：

app.request.matcher:
    class: Symfony\Component\HttpFoundation\RequestMatcher

sylius.listener.checkout_redirect:
    class: Sylius\Bundle\CoreBundle\Checkout\CheckoutRedirectListener
    tags:
        - { name: 'kernel.event_listener', event: 'sylius.order.post_address',  method: 'handleCheckoutRedirect'}
        - { name: 'kernel.event_listener', event: 'sylius.order.post_select_shipping',  method: 'handleCheckoutRedirect'}
        - { name: 'kernel.event_listener', event: 'sylius.order.post_payment',  method: 'handleCheckoutRedirect'}
        - { name: 'kernel.event_listener', event: 'sylius.order.post_test',  method: 'handleCheckoutRedirect'}
    arguments:
        - '@request_stack'
        - '@sylius.router.checkout_state'
        - '@app.request.matcher'

您可以创建 CompilerPass 并向服务添加标签

<?php

namespace App\DependencyInjection\Compiler;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class CustomPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $container
            ->getDefinition('sylius.listener.checkout_redirect')
            ->addTag('kernel.event_listener', [
                'event' => 'sylius.order.post_test',
                'method' => 'handleCheckoutRedirect',
            ]);
    }
}
