README

基于Google reCaptcha API 2.0 和 3.0。

升级到2.x版本

警告！类ReCaptcha和ReCaptchaValidator已弃用。请将它们替换为ReCaptchaConfig、ReCaptcha2和ReCaptchaValidator2。

安装

安装此扩展的首选方式是通过composer。

• 运行以下命令之一

php composer.phar require --prefer-dist "himiklab/yii2-recaptcha-widget" "*"

或者

"himiklab/yii2-recaptcha-widget" : "*"

将以下内容添加到应用程序的composer.json文件的require部分。

• 注册reCAPTCHA API密钥.

• 在配置文件（web.php）中配置组件。siteKey和secret参数是可选的。但如果您省略了它们，您需要在每个验证规则和每个希望使用此小部件的视图中设置它们。如果个别视图或验证规则中设置了siteKey或secret，则将覆盖配置中的设置。

'components' => [
    'reCaptcha' => [
        'class' => 'himiklab\yii2\recaptcha\ReCaptchaConfig',
        'siteKeyV2' => 'your siteKey v2',
        'secretV2' => 'your secret key v2',
        'siteKeyV3' => 'your siteKey v3',
        'secretV3' => 'your secret key v3',
    ],
    ...

或使用DI容器

'container' => [
    'definitions' => [
        himiklab\yii2\recaptcha\ReCaptcha2::className() => function ($container, $params, $config) {
            return new himiklab\yii2\recaptcha\ReCaptcha2(
                'your siteKey v2',
                '', // default
                $config
            );
        },
        himiklab\yii2\recaptcha\ReCaptchaValidator2::className() => function ($container, $params, $config) {
            return new himiklab\yii2\recaptcha\ReCaptchaValidator2(
                'your secret key v2',
                '', // default
                null, // default
                null, // default
                $config
            );
        },
    ],
],

• 在您的模型中添加ReCaptchaValidator2或ReCaptchaValidator3，例如

v2

public $reCaptcha;

public function rules()
{
  return [
      // ...
      [['reCaptcha'], \himiklab\yii2\recaptcha\ReCaptchaValidator2::className(),
        'secret' => 'your secret key', // unnecessary if reСaptcha is already configured
        'uncheckedMessage' => 'Please confirm that you are not a bot.'],
  ];
}

v3

public $reCaptcha;

public function rules()
{
  return [
      // ...
      [['reCaptcha'], \himiklab\yii2\recaptcha\ReCaptchaValidator3::className(),
        'secret' => 'your secret key', // unnecessary if reСaptcha is already configured
        'threshold' => 0.5,
        'action' => 'homepage',
      ],
  ];
}

使用方法

例如

v2

<?= $form->field($model, 'reCaptcha')->widget(
    \himiklab\yii2\recaptcha\ReCaptcha2::className(),
    [
        'siteKey' => 'your siteKey', // unnecessary is reCaptcha component was set up
    ]
) ?>

v3

<?= $form->field($model, 'reCaptcha')->widget(
    \himiklab\yii2\recaptcha\ReCaptcha3::className(),
    [
        'siteKey' => 'your siteKey', // unnecessary is reCaptcha component was set up
        'action' => 'homepage',
    ]
) ?>

或者

v2

<?= \himiklab\yii2\recaptcha\ReCaptcha2::widget([
    'name' => 'reCaptcha',
    'siteKey' => 'your siteKey', // unnecessary is reCaptcha component was set up
    'widgetOptions' => ['class' => 'col-sm-offset-3'],
]) ?>

v3

<?= \himiklab\yii2\recaptcha\ReCaptcha3::widget([
    'name' => 'reCaptcha',
    'siteKey' => 'your siteKey', // unnecessary is reCaptcha component was set up
    'action' => 'homepage',
    'widgetOptions' => ['class' => 'col-sm-offset-3'],
]) ?>

• 注意：请禁用ReCaptcha字段的ajax验证！
