表单提交的 Cakephp3 前缀路由不起作用

Question

我正在玩路由。我想要实现的是像“customer/customer_slug/...”这样的 URL，因此，它将是 /customer/test/hosts/add 或 /customer/acme/networks/list。我已经设置了以下路线...

Router::prefix('customer', function (RouteBuilder $routes){

    $routes->connect('/',['controller' => 'Customers', 'action' => 'index']);
//    ->setMethods(['GET','POST']);

    $routes->connect('/add',['controller' => 'Customers', 'action' => 'add'])
    ->setMethods(['GET','POST']);

    $routes->connect('/:slug/edit',['controller' => 'Customers', 'action' => 'edit'])
    ->setMethods(['GET','POST'])
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']);

    $routes->connect('/:slug',['controller' => 'Customers', 'action' => 'overview'])
    ->setMethods(['GET','POST'])
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']);

    $routes->connect('/:slug/:controller', ['action' => 'index'],['routeClass' => DashedRoute::class])
    ->setMethods(['GET','POST'])
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']);

    $routes->connect('/:slug/:controller/:action', ['param'=>'slug'],['routeClass' => DashedRoute::class])
    ->setMethods(['GET','POST'])
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']);

    $routes->connect('/:slug/:controller/:action/*', [],['routeClass' => DashedRoute::class])
    ->setMethods(['GET','POST'])
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']); 

    // TODO:  Understand and look to remove this 
    $routes->fallbacks(DashedRoute::class);

});

我可以在我的测试中访问 URL，这很好。但是，当我转到 /customer/acme/edit 时，我会在 Customer/CustomersController.php 上获得编辑操作，它会显示适当的表单。查看路由是调试包，它说它正在使用以下路由：

customer:customers:edit /customer/:slug/edit    
{
    "controller": "Customers",
    "action": "edit",
    "prefix": "customer",
    "plugin": null,
    "_method": [
        "GET",
        "POST"
    ]
}

这是我所期望的。但是，当我提交表单时，它会将路由更改为：

customer:_controller:_action    /customer/{controller}/{action}/*   
{
    "prefix": "customer",
    "plugin": null,
    "action": "index"
}

如果我从前缀部分中删除 $routes->fallbacks(...，则会收到 CSRF 错误。

我的编辑页面很简单

<?php $this->extend('../../Layout/TwitterBootstrap/dashboard'); ?>

<?php $this->start('tb_actions'); ?>
<li><?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $customer->id], ['confirm' => __('Are you sure you want to delete # {0}?', $customer->id), 'class' => 'nav-link']) ?></li>
<li><?= $this->Html->link(__('List Customers'), ['action' => 'index'], ['class' => 'nav-link']) ?></li>

<?php $this->end(); ?>
<?php $this->assign('tb_sidebar', '<ul class="nav flex-column">' . $this->fetch('tb_actions') . '</ul>'); ?>

<div class="customers form content">
    <?= $this->Form->create($customer) ?>
    <fieldset>
        <legend><?= __('Edit Customer') ?></legend>
        <?php
            echo $this->Form->control('name');
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>
</div>

来自控制器的相关代码是

    public function edit($slug = null)
    {
        $customer = $this->Customers->getbySlugID($slug);

        if ($this->request->is(['patch', 'post', 'put'])) {
            $customer = $this->Customers->patchEntity($customer, $this->request->getData());
            if ($this->Customers->save($customer)) {
                $this->Flash->success(__('The customer has been saved.'));

                exit;
                return $this->redirect(['controller'=>false, 'action' => 'index', $customer->slug]);

            }
            $this->Flash->error(__('The customer could not be saved. Please, try again.'));
        }
        $this->set(compact('customer'));
    }

查看生成的 URL 代码

<form method="post" accept-charset="utf-8" role="form" action="/customer/customer4/edit"><div style="display:none;"><input type="hidden" name="_method" value="PUT"></div>    <fieldset>
        <legend>Edit Customer</legend>
        <div class="form-group text required"><label for="name">Name</label><input type="text" name="name" required="required" maxlength="40" id="name" class="form-control" value="Customer4"></div>    </fieldset>
    <button type="submit" class="btn btn-secondary">Submit</button>    </form>

所以看起来它应该发布到正确的位置（customer4 是记录的 slug）。

问题是为什么Cake在请求编辑页面时能够获取到正确的路由，但是在发帖时却选择了不同的路由？

注意：我认为还有其他一些路由错误，好像我删除了后备，然后我的 / 路由不起作用。

对于上下文，以下工作正常：

/customer/add 用于编辑和表单提交。

CakePHP 版本为 3.8.8

CakePHP 表单默认使用（模拟）PUT 进行更新（请参阅生成表单中隐藏的_method 字段。是的，是否应该更好地使用PATCH 是有争议的，但它就是这样)，并且您将路由限制为GET 和POST，因此在提交表单时它们都不会匹配，而后备路由将匹配请求，因为它们不应用任何 HTTP 方法限制。

长话短说，确保您的 /edit 路由也至少接受 PUT：

$routes
    ->connect('/:slug/edit',['controller' => 'Customers', 'action' => 'edit'])
    ->setMethods(['GET', 'POST', 'PUT']) // <<<<<< there
    ->setPatterns(['slug'=>'[a-z0-9-_]+'])
    ->setPass(['slug']);

您的控制器还接受 PATCH，这是 Bake 创建的默认值，但如果您实际上不使用或不想接受 PATCH 请求，那么您当然可以放弃它。
