带有 Curl 的 HTTPS 请求失败：0 但在 Curl PHP 中没有响应

Question

我正在尝试使用 HTTPS 链接发出肥皂请求。 我得到 Curl Failed: 0 （这意味着没有错误）但是，我收到了一个空字符串。

$url = $soapUrl;

$soap_do = curl_init();
set_time_limit(0);
curl_setopt($soap_do, CURLOPT_URL,            $url);
curl_setopt($soap_do, CURLOPT_AUTOREFERER,    true);
curl_setopt($soap_do, CURLOPT_MAXREDIRS,      10);
curl_setopt($soap_do, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($soap_do, CURLOPT_POST,           true );
curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $xml_post_string);
curl_setopt($soap_do, CURLOPT_VERBOSE,        TRUE);
curl_setopt($soap_do, CURLOPT_HTTPHEADER,     $headers);

$response = curl_exec($soap_do);
$error    = curl_error($soap_do);

var_dump($response);

echo "Curl Failed: " . curl_errno($soap_do), "<br/>";
echo curl_error($soap_do);

我的代码有问题吗？

Answer 1

你的curl_exec();在哪里？

您设置了大量选项，但我认为大多数选项只是用于微调。 你可以试试我在另一个答案中给出的这个例子：

Send an XML post request to a web server with CURL

编辑： PHP 还内置了一个 SOAP 客户端，也许你可以尝试一下：

    $context = stream_context_create([
        'http' => [
            'user_agent' => 'PHPSoapClient'
        ],
        'ssl' => [
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
        ]
    ]);

    $soap = new SoapClient($url, [
        'stream_context' => $context,
        'cache_wsdl' => WSDL_CACHE_NONE, // WSDL_CACHE_MEMORY
        'trace' => 1,
        'exception' => 1,
        'keep_alive' => false,
        'connection_timeout' => 500000
    ]);

    // Then call the SOAP method
    echo $soap->version();
