Why is my post controller returning a 404?

Question

I've created and enabled a module at app/code/Post/Test:

app/code/Post/Test/registration.php:

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

app/code/Post/Test/etc/module.xml:

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

app/code/Post/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 id="post_test" frontName="posttest"> <module name="Post_Test" /> </route> </router> </config>

app/code/Post/Test/Controller/Test:

<?php namespace Post\Test\Controller; use Magento\Framework\Controller\Result\Raw; use Magento\Framework\App\Action\HttpPostActionInterface; class Test implements HttpPostActionInterface { private $raw; public function __construct(Raw $raw) { $this->raw = $raw; } public function execute() { return $this->raw->setContents('foo bar baz'); } }

Based on this, I think that my controller should be accessible via a POST request to: http://localhost/posttest/test, but it just gives me a 404.

What am I doing wrong?

try with localhost/posttest/test/test

First of all the routing that Magento uses is in the format http://example.com/route_name/controller/action. So to use your route http://localhost/posttest/test create Index.php inside app/code/Post/Test/Controller/Test folder. I am sharing the action code for get request below.

app/code/Post/Test/Controller/Test/Index.php:

<?php namespace Post\Test\Controller\Test; use Magento\Framework\App\Action\HttpGetActionInterface; class Index implements HttpGetActionInterface { public function execute() { echo "controller action"; exit; } }

For post request you need to change the controller above and also need to use the csrf token in the form.

You are Hitting a Get Request in a Controller implemented with HttpPostActionInterface

try to change the interface from HttpPostActionInterface to HttpGetActionInterface

like this

use Magento\Framework\App\Action\HttpGetActionInterface; class Index implements HttpGetActionInterface { public function execute() { //TODO do what you want } }

I think this is the pattern that Magento uses :

http://localhost.com/exmapleroute_name/controller/action

So to use your route http://localhost/posttest/test create Index.php inside

app/code/Post/Test/Controller/Test folder.

All of these answers helped me understand the organization/structure for controllers but it turns out that my problem was that I was submitting the POST request from Postman, which wasn't including the CSRF token. I would have expected that a forbidden error would have been returned if it was failing CSRF but it was still just giving me a 404.

I ended up writing the class like this:

class Index extends Action implements HttpPostActionInterface

And then submitted the form via my site and it worked.
