Question

<?php echo $form->field($model, 'captcha')->widget(Captcha::className(), [
                                              ]); ?>

在yii2要求中传递了要求，如GD和imagick liberies，但验证码图像没有显示。

Answer 1

} else {
        ob_clean();  //Add this line, can solve this problem. Or add in other suitable places
        $this->setHttpHeaders();
        Yii::$app->response->format = Response::FORMAT_RAW;
        return $this->renderImage($this->getVerifyCode());
    }

这会有所帮助，请更改\ vendor \ yiisoft \ yii2 \ captcha \ CaptchaAction.php并显示图片。

Answer 2

你必须设置验证码＆＃39;模型中的规则。

['captcha', 'captcha', 'captchaAction' => 'site/captcha']

第一个验证码是您的财产，下一个是规则类型

务必设置控制器

public function actions()
    {
        return [
            'error' => [
                'class' => 'yii\web\ErrorAction',
            ],
            'captcha' => [
                'class' => 'yii\captcha\CaptchaAction',
                'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
            ],
        ];
    }

Answer 3

} else {
    ob_clean();  //Add this line, can solve this problem. Or add in other suitable places
    $this->setHttpHeaders();
    Yii::$app->response->format = Response::FORMAT_RAW;
    return $this->renderImage($this->getVerifyCode());
}

Yii2验证图片没有显示
