Question

我将reCaptcha集成到测试表单中，因此我们可以使用reCaptcha来停止bot。在完成所有前端和服务器端代码之后，我想测试用户是否成功完成了reCatpha-但是当我检查reCaptcha管理员时，我看到以下消息：

“我们检测到您的网站在不到50％的时间内验证reCAPTCHA通过的解决方案。这可能表明您与reCAPTCHA集成存在问题。请访问我们的开发者网站以获取更多信息。”

我的服务器端验证在做什么错。我已经检查了Stackoverflow和其他站点的PHP解决方案，但没有任何解决方案。

这是我的代码简化了。

Answer 1

我在reCAPTCHA管理员中也遇到了相同的错误。传递密钥时，您没有使用过isset，还使用了urlencode函数。这样，希望这能解决您的问题。

if(isset($_POST['captcha']) && !empty( $_POST['captcha'])){
       $response=$_POST['captcha'];

}

$url = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secret) .  '&response=' . urlencode($response));

            $url = "https://www.google.com/recaptcha/api/siteverify?secret=$secretKey&response=$responseKey";
            $responseFile = file_get_contents($url); // send the $url to the Google reCaptcha server for validation and get a response back
            $responseJSON = json_decode($responseFile); // decode the content of the $response

            }
        }
