cURL错误35 -连接到api.rkd.reuters.com:443的未知SSL协议错误

Question

从开发机器(mac)来说，通过PHP中的cURL连接到这里没有问题，但是在Ubuntu中，我得到了这个错误。我已经在本地机器和Amazon实例上尝试过了。我在谷歌上搜索过，一直到砖墙前。没有防火墙限制，这完全是个谜。php5-curl安装在ubuntu中，我只是没有任何想法。我执行了这个命令：

curl -v https://api.rkd.reuters.com/api/2006/05/01/TokenManagement_1.svc/Anonymous

得到了这个输出，没有任何解决方案的线索。还安装了OpenSSL。

* About to connect() to api.rkd.reuters.com port 443 (#0)
*   Trying 159.220.40.240... connected
* successfully set certificate verify locations:
*   CAfile: none
  CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to api.rkd.reuters.com:443 
* Closing connection #0
curl: (35) Unknown SSL protocol error in connection to api.rkd.reuters.com:443

对此，任何欢迎的想法

我也遇到了同样的问题，不幸的是，一个主机不愿升级到php 5.5。

我通过创建一个新的类扩展php的SoapClient来使用cURL来解决这个问题：

/**
 * New SoapClient class.
 * This extends php's SoapClient,
 * overriding __doRequest to use cURL to send the SOAP request.
 */
class SoapClientCurl extends SoapClient {

  public function __doRequest($request, $location, $action, $version, $one_way = NULL) {
$soap_request = $request;
$header = array(
  'Content-type: application/soap+xml; charset=utf-8',
  "Accept: text/xml",
  "Cache-Control: no-cache",
  "Pragma: no-cache",
  "SOAPAction: \"$action\"",
  "Content-length: " . strlen($soap_request),
);
$soap_do = curl_init();
$url = $location;
$options = array(
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_HEADER => FALSE,
  //CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_SSL_VERIFYHOST => 0,
  CURLOPT_SSL_VERIFYPEER => FALSE,
  CURLOPT_RETURNTRANSFER => TRUE,
  //CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)',
  CURLOPT_VERBOSE => true,
  CURLOPT_POST => TRUE,
  CURLOPT_URL => $url,
  CURLOPT_POSTFIELDS => $soap_request,
  CURLOPT_HTTPHEADER => $header,
  CURLOPT_FAILONERROR => TRUE,
  CURLOPT_SSLVERSION => 3,
);

curl_setopt_array($soap_do, $options);
$output = curl_exec($soap_do);
if ($output === FALSE) {
  $err = 'Curl error: ' . curl_error($soap_do);
}
else {
  ///Operation completed successfully
}
curl_close($soap_do);

// Uncomment the following line to let the parent handle the request.
//return parent::__doRequest($request, $location, $action, $version);
return $output;
  }

}

我遇到了这个问题，我通过将curl版本设置为版本3来修复它。

curl_setopt($ch, CURLOPT_SSLVERSION,3);

显然，服务器开始需要server 3，此设置导致带有SSL的cURL重新开始工作。

修好了！这是一个已知的Ubuntu12.04问题

这些指示

--取消它，它只是禁用了异常，这仍然不起作用！帮助!

-编辑-这是我到底是怎么修好它的！

我从5.4.3升级到PHP 5.5，并在调用中设置了以下选项，并对其进行了修正：

$options = array('ssl_method' => SOAP_SSL_METHOD_SSLv3,'soap_version' => SOAP_1_2);
$sc = new SoapClient('https://my-url.com/call/', $options);

升级是必要的，因为php5 < 5.5中不存在常量SOAP_SSL_METHOD_SSLv3，不幸的是，Ubuntu当时只允许通过apt更新php5升级到5.4.3。我手动安装了以后的版本，现在运行良好。
