推荐答案

我分享我的code解决方案。但是的 proxy.php 的等细节与​​完整的解释，你可能会发现的此处。

I share my code solution. But the proxy.php and other details with the full explanation you might find here.

<script src="https://www.google.com/recaptcha/api.js" >;
<form method="post">
<div class="g-recaptcha" data-sitekey="[site_key]" data-callback="onReturnCallback" data-theme="light"></div>
<input value="submit" type="submit" />
</form>

JS的验证

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">
var onReturnCallback = function(response) { 
    //alert('g-recaptcha-response: ' + grecaptcha.getResponse()); 
    var url='proxy.php?url=' + 'https://www.google.com/recaptcha/api/siteverify';  
    $.ajax({ 'url' : url, 
               dataType: 'json',
               data: { response: response},
               success: function( data  ) {                     
                var res = data.success.toString();
                        alert( "User verified: " + res);                    
                if (res ==  'true') { 
                       document.getElementById('g-recaptcha').innerHTML = 'THE CAPTCHA WAS SUCCESSFULLY SOLVED'; 
                                } 
                           } // end of success: 
         }); // end of $.ajax 
}; // end of onReturnCallback 
</script>
