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）在某些请求参数设置不正确的情况下返回500。

要避免“ 500错误”（例如），请务必：

如果需要，使用

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

使用

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

$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: " . $getInfo['http_code'];//as preline
if (curl_error($ch)){
    $output .= "\n". curl_error($ch);
}
}

curl_close($ch);

echo $output;

顺便说一句：确保已安装CURL模块。

您的服务器或服务器上执行的脚本有问题，可能会抛出未处理的异常。

您应该检查服务器的访问和错误日志。

cURL + HTTP_POST，不断出现500错误。不知道？
