recaptcha v2未获得；“成功”；

我在执行recaptcha v2 chekbox时遇到问题。我首先在我的表单中实现，它只在本地服务器中工作。在多次尝试失败后，我搜索了一些代码，并使用教程中的原始代码，不断出现错误。 网址： 希望有人能帮忙。谢谢

在我的表单中尝试实现复选框recaptcha v2之后，我尝试实现不可见的recaptcha v2，这一个非常有效。我不知道这怎么会发生！你可以在函数中看到

我不知道这是否与我的ssl证书有关（来自let's encrypt）

这对我帮助很大

谢谢你的评论
 我遇到了完全相同的问题，我在下面发布了我的解决方案

我的测试解决方案是：

$google_url = "https://www.google.com/recaptcha/api/siteverify";
$secret_key = 'YOUR_SECRET_KEY';

$response = $_POST['g-recaptcha-response']; 

$message  = 'Google reCaptcha Test';

if(!empty($response))
{
    $url = $google_url."?secret=".$secret_key."&response=".$response;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_TIMEOUT, 15);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, TRUE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, TRUE); 
    $curlData = curl_exec($curl);

    curl_close($curl);

    $res = json_decode($curlData, TRUE);
    if($res['success'] == 'true') 
        $message = "Success!";
    else
        $message = "Enter captcha again!";
}

您遇到了什么错误？我没有得到“成功”的响应，因此我得到了“请检查验证码格式2”，而不是使用带有“请检查验证码格式2”的警报，只是
console.log（$response）
来调试抱歉，没有起作用：（这只会将消息错误替换为nothing。问题是，当发送recaptcha时，google的响应是success==false。你知道如何调试web吗？使用开发工具？控制台和网络（如果你知道网络调用的样子）是有用的谢谢！！我会试试看
