Question

我正在使用的Cakephp版本是 3.4.x

我的cakephp 3应用程序中有十几种表单。我想为所有表单实现xss过滤。如果不对所有表单函数进行更改，最简单的方法是什么。

我在一个答案中读到，为了清理视图，我们应该使用CakePHP便利函数h（$ string），这将使所有对XSS的尝试完全无害。

我尝试了这个但是id没有用完。

\ SRC \模板\用户\ view.ctp

<p><span>Address</span>: <?= h($user->address) ?></p>

在将数据保存到数据库之前，有没有办法实现xss过滤？

我的控制器功能（为我烘焙的cakephp）用于添加新用户及其信息

\ SRC \控制器\ UsersController.php

public function add(){
    $this->viewBuilder()->setLayout('admin')  ;
    $user = $this->Users->newEntity();
    if ($this->request->is('post')) {
        $user = $this->Users->patchEntity($user, $this->request->getData());
        if ($this->Users->save($user)) {
            $this->Flash->success(__('The user has been saved.'));

            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('The user could not be saved. Please, try again.'));
    }
    $groups = $this->Users->Groups->find('list', ['limit' => 200]);
    $this->set(compact('user', 'groups'));
    $this->set('_serialize', ['user']);
}

\ SRC \模型\表\ UsersTable.php

public function beforeSave(Event $event)
{
    $entity = $event->getData('entity');

    if ($entity->isNew()) {
        $hasher = new DefaultPasswordHasher();

        // Generate an API 'token'
        $entity->api_key_plain = sha1(Text::uuid());

        // Bcrypt the token so BasicAuthenticate can check
        // it during login.
        $entity->api_key = $hasher->hash($entity->api_key_plain);
    }
    return true;
}

谢谢！

您可以在User Entity类中使用mutator方法：

class User extends Entity
{    
    protected function _setAddress($value) {
        return strip_tags($value);
    }
}

使用此mutator，您可以在每次更新或创建实体时保存到数据库之前修改输入数据。有关mutator的更多信息：https://book.cakephp.org/3.0/en/orm/entities.html#accessors-mutators

您也可以使用其他方式，但我在此前写过。如果您想使用，您应该测试此代码。使用$entity->getDirty()方法，我们可以获取所有已修改的字段，并在Table::beforeSave()方法中更改其值：

public function beforeSave($event)
{
    $entity = $event->getData('entity');

    $modified = $entity->getDirty();
    foreach((array) $modified as $v) {
        if(isset($entity->{$v})) {
            $entity->{$v} = strip_tags($entity->{$v});
        }
    }

    return true;
}
