ZF2、ZF2-NoCaptcha、FormValidation

Question

我正在使用szmnmichalowski/ZF2-NoCaptcha 进行验证码验证，并且我有以下设置。如何使用 Identical 验证器来验证 'captcha' 表单元素，其中生成并嵌入动态表单中的 'g-recaptcha-response'？即使我输入正确的验证码，我也会收到“两个给定的令牌不匹配”错误消息。但我可以使用自定义验证器对其进行验证。

composer.json

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.3",
        "spoonx/sxmail": "1.4.*",
        "slm/queue": "0.4.*",
        "szmnmichalowski/zf2-nocaptcha": "dev-master"
    }
}

config/application.config.php

return array(
    'modules' => array(
        'SxMail',
        'SlmQueue',
        'Application',
        'NoCaptcha'
    )
