如何在Yii-2应用程序中添加验证码？ [英] How to add captcha in Yii-2 application?

问题描述

我正在尝试将验证码添加到登录表单。

I'm trying to add the captcha to the login form.

我的环境：

• Yii 2


• php 5.4.45 TS


• IIS 10.0


• Windows 10

• Yii 2
• php 5.4.45 TS
• IIS 10.0
• Windows 10

在 login.php ， LoginForm.php中和 SiteController.php 我添加了以下内容（仅显示了相关部分）：

In login.php, LoginForm.php and SiteController.php I added the following (shown only the relevant parts):

backend\views\site\login.php：

backend\views\site\login.php:

use yii\captcha\Captcha;
...
<?= $form->field($model, 'captcha')->widget(Captcha::className()) ?>
...

common\models\LoginForm.php：

common\models\LoginForm.php:

...
public $captcha;
...
public function rules()
{
    return [
        ... 
        [['username', 'password', 'captcha'], 'required'],           
        ['captcha', 'captcha'],
    ];
}

后端\控制器lerSiteController.php：

backend\controllers\SiteController.php:

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

我已经下载并安装了 ImageMagick-7.0.2-Q16

如此处我已经下载了php_imagick-3.4.1-5.4-ts-vc9-x86 .zip并从那里解压缩php_imagick.dll。然后在 / php / ext /

As described here I have downloaded php_imagick-3.4.1-5.4-ts-vc9-x86.zip and extract php_imagick.dll from there. Then added php_imagick.dll in /php/ext/

在 php.ini中添加php_imagick.dll 我添加了以下内容：

...
[PHP_IMAGICK]
extension=php_imagick.dll
...

然后重新启动IIS，但不会显示验证码，并且我在日志中看到以下内容：

Then restart IIS, but captcha is not displayed and I see the following in the logs:

2016-08-10 07:28:21 [127.0.0.1][-][h1a65krn8scqc9auk56flmesi6][error][yii\base\InvalidConfigException] exception 'yii\base\InvalidConfigException' with message 'Either GD PHP extension with FreeType support or ImageMagick PHP extension with PNG support is required.' in C:\projects\aisnew\vendor\yiisoft\yii2\captcha\Captcha.php:180

重新启动操作系统后：

2016-08-10 07:01:22 [127.0.0.1][-][h1a65krn8scqc9auk56flmesi6][error][yii\base\ErrorException:32] exception 'yii\base\ErrorException' with message 'PHP Startup: ' in Unknown:0

我在某处阅读到最新版本正在Windows 10上运行，但需要安装Visual C ++ 2013 Redistributable Package。我检查是否已安装此软件包。

I read somewhere that the most recent version is working on Windows 10 but need to install the Visual C++ 2013 Redistributable Package. I checked that this package is installed.

推荐答案

我认为这应该可行

<?= $form->field($model, 'captcha')->widget(Captcha::className(), 
            ['template' => '<div class="captcha_img">{image}</div>'
                . '<a class="refreshcaptcha" href="#">'
                . Html::img('/images/imageName.png',[]).'</a>'
                . 'Verification Code{input}',
            ])->label(FALSE); ?> 

我所做的是，添加了一个包含验证码图像，刷新验证码图像的模板（提供适当的路径），该字段的标签和文本的输入字段。

what i have done is, added a template which contains a captcha image, a refresh captcha image(provide suitable path), a label to the field and an input field for text.
