Question

我的表格中有Google的reCAPTCHA。但是我遇到了它返回的json格式的问题：在文档中，

https://developers.google.com/recaptcha/docs/verify#api-request：

{
 "success": true|false,
 "challenge_ts": timestamp,  // timestamp of the challenge load (ISO format yyyy-MM-dd'T'HH:mm:ssZZ)
 "hostname": string,         // the hostname of the site where the reCAPTCHA was solved
 "error-codes": [...]        // optional
}

但我收到了这个回复：

{
 "success": true,
 "challenge_ts": "2016-06-13T06:46:40Z",
 "hostname": "devs.mysite.com.au"
} {"success":false,"errors":[null]}'

导致一些错误。我的代码是：

$is_valid = $_POST['g-recaptcha-response'];
$url = 'https://www.google.com/recaptcha/api/siteverify';
$fields = array(
    'secret' => 'mysecretcode',
    'response' => $is_valid,
    'remoteip', ''
);

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);

Google API的json输出符合预期。我对json不太熟悉，但我希望[...]参数的error-codes指定它包含任何东西：

 "error-codes": [...]

它返回的是一个json对象（这是花括号的意思，见the json specification）。实际上，它返回一个具有两个属性的对象：success和errors：

{"success":false,"errors":[null]}'

Google reCAPTCHA返回错误的json响应
