如何从 PHP 发布 SOAP 请求

Question

有人知道我如何从 PHP 发布 SOAP 请求吗？

Answer 1

根据我的经验，事情并不是那么简单。内置的PHP SOAP client 不适用于我们必须使用的基于.NET 的SOAP 服务器。它抱怨无效的模式定义。即使 .NET 客户端与该服务器配合得很好。顺便说一句，让我声明 SOAP 互操作性是一个神话。

下一步是NuSOAP。这工作了很长一段时间。顺便说一句，看在上帝的份上，别忘了缓存 WSDL！但即使使用 WSDL 缓存，用户也抱怨这该死的东西很慢。

然后，我们决定使用纯 HTTP，组装请求并使用 SimpleXMLElemnt 读取响应，如下所示：

$request_info = array();

$full_response = @http_post_data(
    'http://example.com/OTA_WS.asmx',
    $REQUEST_BODY,
    array(
        'headers' => array(
            'Content-Type' => 'text/xml; charset=UTF-8',
            'SOAPAction'   => 'HotelAvail',
        ),
        'timeout' => 60,

    ),
    $request_info
);

$response_xml = new SimpleXMLElement(strstr($full_response, '<?xml'));

foreach ($response_xml->xpath('//@HotelName') as $HotelName) {
    echo strval($HotelName) . "\n";
}

请注意，在 PHP 5.2 中，您需要 pecl_http，因为（惊喜！）没有内置 HTTP 客户端。

使用裸 HTTP 使我们的 SOAP 请求时间提高了 30% 以上。 从那时起，我们将所有性能抱怨都重定向到服务器人员。

最后，我推荐后一种方法，而不是因为性能。我认为，一般来说，在像 PHP 这样的动态语言中，所有 WSDL/类型控制没有任何好处。您不需要花哨的库来读取和写入 XML，所有这些存根生成和动态代理。您的语言已经是动态的，SimpleXMLElement 工作得很好，而且非常易于使用。此外，您将拥有更少的代码，这总是好的。

PHP 支持 SOAP。 只需拨打电话

$client = new SoapClient($url);

连接到SoapServer，然后你就可以得到函数列表和调用函数了……

$client->__getTypes();      
$client->__getFunctions();  

$result = $client->functionName();

我需要执行许多非常简单的 XML 请求，在阅读了@Ivan Krechetov 关于 SOAP 速度影响的评论后，我尝试了他的代码并发现 http_post_data() 没有内置到 PHP 5.2 中。我真的不想安装它，我尝试了我所有服务器上的 cURL。虽然我不知道 cURL 与 SOAP 相比有多快，但它确实很容易满足我的需求。下面是一个带有 cURL 的示例，供任何需要它的人使用。

$xml_data = '<?xml version="1.0" encoding="UTF-8" ?>
<priceRequest><customerNo>123</customerNo><password>abc</password><skuList><SKU>99999</SKU><lineNumber>1</lineNumber></skuList></priceRequest>';
$URL = "https://test.testserver.com/PriceAvailability";

$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml_data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);


print_r($output);

我们可以使用 PHP cURL 库来生成简单的 HTTP POST 请求。以下示例向您展示了如何使用 cURL 创建一个简单的 SOAP 请求。

创建soap-server.php，将SOAP请求写入web文件夹中的soap-request.xml。

We can use the PHP cURL library to generate simple HTTP POST request. The following example shows you how to create a simple SOAP request using cURL.

Create the soap-server.php which write the SOAP request into soap-request.xml in web folder.


<?php
  $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
  $f = fopen("./soap-request.xml", "w");
  fwrite($f, $HTTP_RAW_POST_DATA);
  fclose($f);
?>


The next step is creating the soap-client.php which generate the SOAP request using the cURL library and send it to the soap-server.php URL.

<?php
  $soap_request  = "<?xml version=\"1.0\"?>\n";
  $soap_request .= "<soap:Envelope xmlns:soap=\"http://www.w3.org/2001/12/soap-envelope\" soap:encodingStyle=\"http://www.w3.org/2001/12/soap-encoding\">\n";
  $soap_request .= "  <soap:Body xmlns:m=\"http://www.example.org/stock\">\n";
  $soap_request .= "    <m:GetStockPrice>\n";
  $soap_request .= "      <m:StockName>IBM</m:StockName>\n";
  $soap_request .= "    </m:GetStockPrice>\n";
  $soap_request .= "  </soap:Body>\n";
  $soap_request .= "</soap:Envelope>";

  $header = array(
    "Content-type: text/xml;charset=\"utf-8\"",
    "Accept: text/xml",
    "Cache-Control: no-cache",
    "Pragma: no-cache",
    "SOAPAction: \"run\"",
    "Content-length: ".strlen($soap_request),
  );

  $soap_do = curl_init();
  curl_setopt($soap_do, CURLOPT_URL, "http://localhost/php-soap-curl/soap-server.php" );
  curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10);
  curl_setopt($soap_do, CURLOPT_TIMEOUT,        10);
  curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($soap_do, CURLOPT_POST,           true );
  curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $soap_request);
  curl_setopt($soap_do, CURLOPT_HTTPHEADER,     $header);

  if(curl_exec($soap_do) === false) {
    $err = 'Curl error: ' . curl_error($soap_do);
    curl_close($soap_do);
    print $err;
  } else {
    curl_close($soap_do);
    print 'Operation completed without any errors';
  }
?>


Enter the soap-client.php URL in browser to send the SOAP message. If success, Operation completed without any errors will be shown and the soap-request.xml will be created.

<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
  <soap:Body xmlns:m="http://www.example.org/stock">
    <m:GetStockPrice>
      <m:StockName>IBM</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>

您可能想查看here 和here。

第一个链接中的一个小代码示例：

<?php
// include the SOAP classes
require_once('nusoap.php');
// define parameter array (ISBN number)
$param = array('isbn'=>'0385503954');
// define path to server application
$serverpath ='http://services.xmethods.net:80/soap/servlet/rpcrouter';
//define method namespace
$namespace="urn:xmethods-BNPriceCheck";
// create client object
$client = new soapclient($serverpath);
// make the call
$price = $client->call('getPrice',$param,$namespace);
// if a fault occurred, output error info
if (isset($fault)) {
        print "Error: ". $fault;
        }
else if ($price == -1) {
        print "The book is not in the database.";
} else {
        // otherwise output the result
        print "The price of book number ". $param[isbn] ." is $". $price;
        }
// kill object
unset($client);
?>

下面是我在this website 找到的如何执行此操作的快速示例（它最好地向我解释了这个问题）。该网站链接还解释了 WSDL，这对于使用 SOAP 服务很重要。

但是，我认为他们在以下示例中使用的 API 地址仍然无效，因此只需切换您自己选择的一个即可。

$wsdl = 'http://terraservice.net/TerraService.asmx?WSDL';

$trace = true;
$exceptions = false;

$xml_array['placeName'] = 'Pomona';
$xml_array['MaxItems'] = 3;
$xml_array['imagePresence'] = true;

$client = new SoapClient($wsdl, array('trace' => $trace, 'exceptions' => $exceptions));
$response = $client->GetPlaceList($xml_array);

var_dump($response);

如果 XML 在不同级别具有相同名称的身份，则有一个解决方案。您不必提交原始 XML（此 PHP SOAP 对象不允许发送原始 XML），因此您必须始终将 XML 转换为数组，如下例所示：

$originalXML = "
<xml>
  <firstClient>
      <name>someone</name>
      <adress>R. 1001</adress>
  </firstClient>
  <secondClient>
      <name>another one</name>
      <adress></adress>
  </secondClient>
</xml>"

//Translate the XML above in a array, like PHP SOAP function requires
$myParams = array('firstClient' => array('name' => 'someone',
                                  'adress' => 'R. 1001'),
            'secondClient' => array('name' => 'another one',
                                  'adress' => ''));

$webService = new SoapClient($someURL);
$result = $webService->someWebServiceFunction($myParams);

或

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch); 
curl_close($ch);

$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);

$parser = simplexml_load_string($response2);
