cURL + HTTP_POST,不断出现500错误.不知道？

Question

好的,我想使用cURL创建HTTP_POST到SSL站点.我已经将证书导入了我的服务器.这是我的代码:

$url  = "https://www.xxx.xxx";
$post = "";# all data that going to send

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0'); 

$exe  = curl_exec($ch);
$getInfo = curl_getinfo($ch);

if ($exe === false) {
    $output = "Error in sending";
    if (curl_error($ch)){
        $output .= "\n". curl_error($ch);
    }
} else if($getInfo['http_code'] != 777){
    $output = "No data returned. Error: " . $getInfo['http_code'];
    if (curl_error($ch)){
        $output .= "\n". curl_error($ch);
    }
}

curl_close($ch);

echo $output;

它保持返回"500".基于w3schools,500表示内部服务器错误.我的服务器有问题吗？如何解决/排除故障？

Answer 1

某些服务器(特别是SSL请求)在请求的某些参数设置不正确的情况下返回500.

为了避免" 500错误 "(例如),请务必:

• 如果需要,设置适当的"Referer:"标题

curl_setopt(CURLOPT_REFERER, 'http://site.com/ref_page');

• 设置正确的"User-Agent:"标题,用

curl_setopt(CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');
