How call Magento 2 module by url (or add route in module)?

Question

I wrote module in Magento 2 and this is my /etc/frontend/routes.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="test" frontName="test">
            <module name="Arthur_Test" />
        </route>
    </router>
</config>

and I have to access to my module from external script to get some data he generate. That data is in app/code/Arthur/Test/storage/data.txt

I cant get that data by exact url (example.com/app/code/Arthur/Test/storage/data.txt) because of 403 Forbidden so I want to call method in my module. How can I do it ?

url example.com/test/ give me 404 Not Found

You need to learn how to create a module. For starters, I can help you create a basic module:

app/code/Arthur/Test/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Arthur_Test',
    __DIR__
);

app/code/Arthur/Test/etc/module.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Arthur_Test" setup_version="1.0.0"/>
</config>

app/code/Arthur/Test/etc/frontend/routes.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route frontName="test" id="test">
            <module name="Arthur_Test"/>
        </route>
    </router>
</config>

app/code/Arthur/Test/Controller/Index/Index.php

<?php


namespace Arthur\Test\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{

    protected $resultPageFactory;

    /**
     * Constructor
     *
     * @param \Magento\Framework\App\Action\Context  $context
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    ) {
        $this->resultPageFactory = $resultPageFactory;
        parent::__construct($context);
    }

    /**
     * Execute view action
     *
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        echo "My controller has been called";die;
        //return $this->resultPageFactory->create();
    }
}

Answer 2

Make router name storage

 <route frontName="storage" id="storage">

The path to controller should be app/code/Arthur/Test/Controller/Storage/Data.php

and the file

<?php namespace Arthur\Test\Controller\Storage;

class Data extends \Magento\Framework\App\Action\Action
{
  echo "test";
}

Now if you call example.com/storage/data it will work
