官方PHP示例代碼：https://github.com/yidun/captcha-php-demo

這裏是基於 laravel 框架來實現

效果圖如下：

封裝service代碼如下：

<?php
namespace App\Services;
/**

    const VERSION = 'v2';

    const API_URL = 'http://c.dun.163yun.com/api/v2/verify';

    protected $secret_id;
    protected $secret_key;

        }
    }
}

新建config/captcha.php 添加如下代碼

<?php
 #聯繫商務獲取祕鑰
return [
    'captcha'=>[
        'CAPTCHA_ID' => env('CAPTCHA_ID'),
        'SECRET_ID' => env('SECRET_ID'),
        'SECRET_KEY' => env('SECRET_KEY'),
    ]
]; 

 .env添加

#captcha
CAPTCHA_ID=CAPTCHA_ID
SECRET_ID=SECRET_ID
SECRET_KEY=SECRET_KEY

二次校驗

public function wangyiVerify(Request $request)
    {
        $validate = $request->input('validate');
         // 文檔地址：http://support.dun.163.com/documents/15588062143475712?docId=69218161355051008
         $CaptchaVerifier = new CaptchaVerifier(config('captcha.captcha.CAPTCHA_ID'),config('captcha.captcha.SECRET_ID'),config('captcha.captcha.SECRET_KEY'));
        //通過則返回true
        $validatePass = $CaptchaVerifier->verify($validate);
        if (!$validatePass) {
            return $this->responseError('驗證不通過');
        }
        return $this->responseSuccess('驗證通過');
    }
