In admin I have the following controller:

<?php
namespace VendorModuleControllerAdminhtml;

use MagentoBackendAppActionContext;

class Test extends MagentoBackendAppAction

 /**
 * @var MagentoFrameworkViewResultPageFactory
 */
 protected $resultPageFactory;

 /**
 * @param MagentoBackendAppActionContext $context
 */
 public function __construct(
 Context $context,
 MagentoFrameworkControllerResultJsonFactory $resultJsonFactory
 ) 
 parent::__construct($context);
 $this->resultJsonFactory = $resultJsonFactory;
 

 public function execute()
 
 return $this->resultJsonFactory->create()->setData([
 'this' => 'test'
 ]);
 

in Vendor/Module/etc/adminhtml/routes.xml I have:

<?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="admin">
 <route id="module" frontName="module">
 <module name="Vendor_Module" />
 </route>
 </router>
</config>

In javascript I do the following ajax request to that controller:

jQuery.ajax( 
 url: location.protocol + '//' + location.host+'/admin/module/test',
 data: form_key: window.FORM_KEY,
 type: 'POST'
 ).done(function(a) 
 console.log(a); 
 );

And I receive 404 error

http://mydomain/admin/module/test?isAjax=true 404 (Forbidden)

as well.. same thing...

Why is this happening ?

you should make the call to location.protocol + '//' + location.host+'/admin/vendor/module/test'

[EDIT]

or try
location.protocol + '//' + location.host+'/admin/module/test'

I had the same issue. The reason could be, that the formkey is invalid, because it is not added to the url.

My advice:

• Do not use location.protocol or something else like location.host
  


• Instead let the url be generated by PHP and then pass it to javascript in phtml file or as a variable (for example in a function created by block).

Creation in PHP (from block) is:

$this->getUrl('frontname/myController', $params )

where:

• 
  frontname is defined in your route-file etc/adminhtml/routes.xml,


• 
  $params are the post-parameters (can be an empty array).

Also it can be a cache-problems:

• Check if you have caches disabled


• run the command: php bin/magento cache:clean
  


• run the command: rm -r var/generation
  

Ок, this does not make any sense to me.

In Vendor/Module/Controller/Adminhtml/ I have the fallowing controllers:

Controller/Adminhtml/Double.php
Controller/Adminhtml/Module/Index.php
Controller/Adminhtml/Test/Test.php

If I send anjax to :

location.protocol + '//' + location.host+'/admin/module/module/index

or

location.protocol + '//' + location.host+'/admin/module/test/test

they both succeed. If I send ajax to ajax to

location.protocol + '//' + location.host+'/admin/module/double

i get

http://mydomain/admin/module/double?isAjax=true 404 (Forbidden)

Wtf is this :) And what is error 404 Forbidden :) ?

I don't know how it is possible, but i had the same error and i fixed it adding

/**
 * Array of actions which can be processed without secret key validation
 *
 * @var string[]
 */
protected $_publicActions = ['test'];

and it starts to work, but now it continues to work even if $_publicActions is removed or commented out.

I use Magento 2.3.0, when I try to upload product image, then I get this error.
?isAjax=true
Anyboady can help me? please, look at this film:
