SOAP与PHP到sapweb服务

因此，我在企业环境中试图做的是在wsdl模式下使用PHP类SoapClient连接到SAP Web服务

到目前为止，我完成的是得到“缺少属性”错误。在解决了所有丢失的属性错误后，我得到了可怕的http错误500，其主体是：soap env:Server

这是我的代码：

class SapTest {
 const SAP_WSDL_URI  = *wsdl_uri*;
 const SAP_USER = *username*;
 const SAP_PWD  = *password*;

public function execute() {

        $client = new SoapClient('http://'.urlencode(self::SAP_USER).':'.urldecode(self::SAP_PWD).'@'.self::SAP_WSDL_URI,
                array("trace" => 1,
                      "exceptions" => 1,
                      "login" => self::SAP_USER,
                      "password" => self::SAP_PWD,
                      'features' => SOAP_SINGLE_ELEMENT_ARRAYS)
        );

        $method = '_-bic_-nf2';

        $parameter = array('ETColumnDescription' => null,
                           'ETGridData' => null,
                           'ETMessageLog' => null,
                           'ETRowDescription' => null,
                           'ISVar_01xwerbet' => array('Sign' => 'I',
                                                      'Option' => 'LE',
                                                      'Low' => '3',
                                                      'High' => null));

        try
        {

        $result = $client->$method($parameter);
        print_r($result);
        } catch(SoapFault $e) {

        echo "REQUEST HEADER:\n" . $client->__getLastRequestHeaders() . "\n";
          echo "REQUEST:\n" . $client->__getLastRequest() . "\n";

          echo "RESPONSE HEADER:\n" . $client->__getLastResponseHeaders() . "\n";

          echo "RESPONSE:\n" . $client->__getLastResponse() . "\n";
        print_r($e);
    }


}

}

$oSap = new SapTest();
$oSap->execute();

我的xml输出如下所示：

预期的xml应如下所示：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:sap-com:document:sap:soap:functions:mc-style">

    <Option>LE</Option>
    <Low>3</Low>
    <High/>
   </ISVar_01xwerbet>
  </ns1:_-bic_-nf2>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我不确定是否是缺少的空白标题标记，我似乎无法用基本PHP添加它（我可以添加标题，但添加空白标题似乎是困难的部分）。或者是不同的前缀（ns1/urn或soapenv/SOAP-ENV），但我开始为此发疯了。非常感谢您的帮助

提前谢谢

您的SOAP请求没有问题

ns1

/

urn

和

soapenv

/

SOAP-ENV

只是表示名称空间的前缀。不同的Web服务引擎生成不同的名称空间前缀，Web服务必须期望它们

SOAP头对于Web服务来说不是必须的，但是如果您的服务需要它，您应该提供它

我建议您与服务提供商谈谈请求出现了什么问题，如果不可能，请使用SOAP测试工具，如

要创建空的SOAP头，请尝试

$header =new SoapHeader('urn:sap-com:document:sap:soap:functions:mc-style', null);
$client->__setSoapHeaders($header);

谢谢你的回答，有没有办法制作一个空白的SOAP头？我得到了一个致命的错误：-（不过，谢谢你，尝试了其他简单的解决方案来解决上述问题？我面临着同样的问题。我需要在wsdl中使用带有wsp策略标记的SAP Pi Webservice。任何帮助都将不胜感激。
