通过PHP中的代理通过SoapClient获取WSDL的错误请求

Question

我有两台服务器：一台用于开发，可以轻松访问WEB，另一台用于生产，只能使用代理访问WEB。

我想从我的生产服务器调用SOAP WEB服务。

所以下面的代码是（网址是假的）：

$url = 'https://www.webservice.com/soap.php'; 
$wsdl = 'https://www.webservice.com/soap.php?wsdl'; 

$client = new SoapClient 
(
     $wsdl, 
     array 
     (
       'location'  => $url, 
       'proxy_host' => 'www.myproxy.com', 
       'proxy_port' => 8080, 
     ) 
); 


$namespace = 'urn:mynamespace'; 
$header = array 
(
     'header1' => 'H1', 
     'header2' => 'H2', 
     'header3' => 'H3', 
); 

$client->__setSoapHeaders(new SoapHeader($namespace, 'myHeader', $header)); 

$params = array 
(
     'param1' => 'val1', 
     'param2' => 'val2', 
     'param3' => 'val3', 
); 

$result = $client->method($params); 

我从我的开发服务器运行它，我得到预期的结果。 现在，我从我的生产服务器上运行它，我得到：

PHP Warning: SoapClient::SoapClient(https://www.webservice.com/soap.php?wsdl): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request 
PHP Warning: SoapClient::SoapClient(): I/O warning : failed to load external entity "https://www.webservice.com/soap.php?wsdl" in /home/benji/test.php on line 20 
PHP Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://www.webservice.com/soap.php?wsdl' : failed to load external entity "https://www.webservice.com/soap.php?wsdl" 

当我wget的从生产服务器的WSDL，它的工作：

$ https_proxy=www.myproxy.com wget https://www.webservice.com/soap.php?wsdl

以下解决方案解决了上述问题对我来说：

• 创建一个新的流上下文，你还可以指定代理信息
• 的流上下文集合选项SNI_enabled假

• 传递流上下文作为新的参数选项数组中的SoapClient的

  $context = stream_context_create(
  array(
      'ssl' => array(
       'SNI_enabled' => false 
      ), 
      'http' => array(
       'proxy' => 'tcp://yourproxy.com:9999' 
      ) 
  ) 
  ); 
  $soapOptions = array(
      'stream_context' => $context 
  ); 
  $soapClient = new SoapClient('wsdl.path', $soapOptions);
