            'sensitive' => false, // 是否对大小写敏感
            'sessionKey' => 'captcha', // 存储session key
            'length' => 4, // 验证码长度
            'charset' => '2346789abcdefghjmnpqrtuxyzABCDEFGHJMNPQRTUXYZ', // 验证码字符集

<img src="<?php echo $captcha?>" onclick="this.src='<?php echo $captcha . '?'?>' + Math.random()" style="cursor: pointer;">

in Controller 控制器文件：

use JZaaa\CakeCaptcha\Captcha;

// 检测验证码是否合法
public function check()
{
    if ($this->request->is('post')) {
        $userCode = $this->request->getData('userCode');

        if (!empty($userCode)) {
            $captcha = new Captcha([
                'session' => $this->request->getSession()
            ]);
            if ($captcha->check($userCode)) {
                // valid
            }
        } else {
                // invalid
        }

    }
}
