README

This module provides behavior, validator and bootstrap to connection reCAPTCHA to Yii2 Application.

Installation

composer require wearesho-team/yii2-recaptcha-v3:^1.1

Usage

Configuration

To configure current reCAPTCHA environment (will be used in Behavior) you have to use ConfigInterface.

Environment Configuration

Bootstrap

<?php

use Wearesho\ReCaptcha;

// config.php

return [
    'bootstrap' => [
        'reCaptcha' => [
            'class' => ReCaptcha\V3\Yii2\Bootstrap::class,
            'config' => ReCaptcha\V3\EnvironmentConfig::class, // or another config interface implementation
            'yiiConfig' => ReCaptcha\V3\Yii2\EnvironmentConfig::class, // will be used for environment checking
        ],
        // another bootstraps      
    ],
];

See wearesho-team/recaptcha-v3 docs for environment config details.

Validator

<?php

use yii\base;
use Wearesho\ReCaptcha;

class Model extends base\Model {
    /** @var string token for reCAPTCHA verification */
    public $token;
    
    public function rules(): array
    {
        return [
            [['token',], 'required',],
            [['token',], ReCaptcha\V3\Yii2\Validator::class,
                'min' => 0.5,
                'max' => 1,
                'actions' => ['login',],
                'hostNames' => ['wearesho.com',],
            ],
        ];
    }
}

See Validator source code for properties details.

Behavior

Behavior is way to validate reCAPTCHA token in web\Controller.

<?php

use yii\web;
use Wearesho\ReCaptcha;

class Controller extends web\Controller 
{
    public function behaviors(): array
    {
        return [
            'reCaptcha' => [
                'class' => ReCaptcha\V3\Yii2\Behavior::class,
                'actions' => [
                    'login' => ['post',],   
                ],
                'min' => 0.5,
                'max' => 1,
                'hostNames' => ['wearesho.com',],
                'environments' => ['prod',],
            ],      
        ];
    }
    
    // controller code
}

If environments property specified, environment check will be performed before others. See configuration section for environment configuring details.

In this example behavior will check for X-ReCaptcha-Token header before login action (only in case of POST action). If header is missing or it's value invalid \yii\web\BadRequestHttpException will be threw. See Behavior source code for code details and property docs.

When checking reCAPTCHA response action attribute will be used current controller ID, action ID and request method: controlleractionmethod, without dividers. Example: loginindexpost, where login is controller ID, index is action ID and post is request method).

Note: Behavior::actions property works different way compared to Validator
