Multiple Issues with Cakephp 4.1

[kujain]

I don't think the documentation is accurate for 4.1. I get errors with:

bin/cake plugin load -rb Recaptcha

Class 'Plugin' not found

if I add manually ($this->addPlugin('Recaptcha');), I get the following error on loading the form:

Helper class RecaptchaHelper could not be found.

Please help!

OK - with some hacking I was able to get the helper working in this way:
Controller:

        $this->loadComponent('Recaptcha.Recaptcha');
	$this->viewBuilder()->addHelper('Recaptcha.Recaptcha');
        .....
    	if ($this->request->is('post')) {
			if ($this->Recaptcha->verify()) {

View:

                    <?= $this->Recaptcha->display(); ?>

Now I see this error on submitting:

Call to a member function getData() on null
Error

  | public function verify()
  | {
  | $controller = $this->_registry->getController();
  | $gRecaptchaResponse = $controller->request->getData("g-recaptcha-response");
  | if (!empty($gRecaptchaResponse)) {
  |  
  | $resp = $this->recaptcha->verifyResponse(
  | new Client(),

There are also a number of warnings showing up like:

Deprecated (16384): notEmpty() is deprecated. Use notEmptyString(), notEmptyArray(), notEmptyFile(), notEmptyDate(), notEmptyTime() or notEmptyDateTime() instead. - //vendor/cakephp-fr/recaptcha/src/Validation/ConfigValidator.php, line: 29
 You can disable all deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED`, or add `vendor/cakephp-fr/recaptcha/src/Validation/ConfigValidator.php` to  `Error.ignoredDeprecationPaths` in your `config/app.php` to mute deprecations from only this file.

Thanks!

I managed to make this work with a few edits to the core code as below:

RecaptchaComponent.php:
change line 14

use Cake\Http\Client;

change line :

        $gRecaptchaResponse = $controller->getRequest()->getData("g-recaptcha-response");

Recaptcha.php:
change line 87:

use Cake\Http\Client;

Could you please review and update if this fix is valid?
Thanks very much!

Seems like this issue was fixed at this pull request: #13

And there's also an opened pull request to fix the deprecation errors for Validator::errors() here: #18
