Magento 2 fail to add a plugin to the Model class - Customer.php

Question

I wrote a plugin to Customer.php, for testing purpose, I added the error_log statement, but it had not been executed when I do the login action. Customer.php in my plugin:

<?php
namespace Vendor\PluginTest\Model\Plugin;

class Customer
{        
    public function afterValidatePassword(\Magento\Customer\Model\Customer $subject,$result)
    {
        error_log('afterValidatePassword');
        return $result;
    }
}

di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Customer\Model\Customer">
        <plugin name="customer-test-module" type="Vendor\PluginTest\Model\Plugin\Customer" sortOrder="1"/>
    </type>
</config>

I can't figure out where's wrong. Anyone can help? Anything I forgot to set? Thanks

Answer 1

i hope you wrote custom module inside vendor, second thing after creating module did you run upgrade cli and you module entry is in app/etc/config.php

Magento 2: rewrite controller

in above link check my post my, module is inside /app/Sugarcode/Test not inside vendor module

Answer 2

Make sure your extension is registered by running php bin/magento module:status.

I don't think Magento\Customer\Model\Customer::validatePassword is used for login password validation. Magento\Customer\Model\AccountManagement::authenticate is where the password is validated when you login on the frontend.
