cURL Recaptcha不能正常使用PHP

Question

我有什么:

$data = array(
            'secret' => "my-app-secret",
            'response' => "the-response"
        );

$verify = curl_init();
curl_setopt($verify, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($verify, CURLOPT_POST, true);
curl_setopt($verify, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($verify, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($verify);

var_dump($response);

我得到了什么 :( bool(false)这意味着curl_exec()失败)

我的期望:JSON对象响应

请帮忙.谢谢.

因为您尝试通过SSL进行连接,所以需要调整cURL选项来处理它.如果你添加,快速解决这个问题就可以了curl_setopt($verify, CURLOPT_SSL_VERIFYPEER, false);

设置CURLOPT_SSL_VERIFYPEER为false将使其接受任何给予它的证书而不是验证它们.

<?php

$data = array(
            'secret' => "my-secret",
            'response' => "my-response"
        );

$verify = curl_init();
curl_setopt($verify, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($verify, CURLOPT_POST, true);
curl_setopt($verify, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($verify, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($verify, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($verify);

var_dump($response);

这是cURL的另一种方法，我发现它可以帮助任何人。显然输入$ secret和$ response变量才能正确传递它。抱歉，问题是要求使用cURL解决方案，但这是我见过的最快的方法，因此我认为无论如何都会添加它，因为我知道它会帮助某个人。:)

$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response=".$response);
$response = json_decode($response, true);
if($response["success"] === true){
    // actions if successful
}else{
    // actions if failed
}

使用带有 POST 的“file_get_contents”更容易：

$postdata = http_build_query( [
    'secret'   => YOUR_SECRET_KEY,
    'response' => $_POST[ 'g-recaptcha-response' ]
] );

$opts = [
    'http' => [
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    ]
];

$context  = stream_context_create( $opts );

$result = file_get_contents(
    'https://www.google.com/recaptcha/api/siteverify', false, $context
);

$check = json_decode( $result );
if( $check->success ) {
    echo "validate";
} else {
    echo "wrong recaptcha";
}
