我正在尝试在公司内部调用远程Web服务。出于专有原因,我无法提供Web服务的URL。该Web服务具有一个称为getItemField的函数。这是我要针对其运行PHP的小型测试服务,服务描述如下:

我可以很好地连接到服务并打印出单个函数的名称和类型,但是当我尝试调用一个函数时,我得到'no SOAPAction header!'。 错误。我调用服务函数的PHP代码如下:
$options = array(
                // Dev
                'soap_version'=>SOAP_1_2,
                'exceptions'=>true,
                'trace'=>1,
                'cache_wsdl'=>WSDL_CACHE_NONE,
                'features' => SOAP_SINGLE_ELEMENT_ARRAYS,

                // Credentials
                'login' => 'user',
                'password' => 'pass'
            );

// Connected successfully
            $client = new SoapClient( "http://myWebsite.com/services/MyFirstWebService?wsdl", $options );

    //Params
        $params = array( '123456' );

        //Options
        $options = array( 'soapaction' => '""' );

        //Call function (Both methods below throw the same 'no SOAPAction header!' error)
        //$result = $client->getItemField( new SoapParam($params, "getItemFieldRequest") );
        $result = $client->__soapCall( "getItemField", array('123456'), $options );

根据服务的描述,似乎没有定义任何肥皂 Action 。我在soapAction上看到的行是<wsdlsoap:operation soapAction=""/>。我尝试指定一个空白的soapAction,因为还没有定义,但是似乎没有用。 Web服务定义本身是否不完整?还是我在客户端应用程序调用中缺少某些参数?提前致谢。

更新:

试图将方法名称指定为soap操作,但是htat无效。
    //Params
    $params = array( '123456' );

    //Options
    $options = array( 'soapaction' => 'getItemField' );

    //Call function (STILL THROWS 'no SOAPAction header!')
    $result = $client->__soapCall( "getItemField", $params, $options );

如果在wsdl中未指定soapAction,即设置为“”,该怎么办。

最佳答案

我有一个类似的问题,但是我使用的是 cURL 而不是 SoapClient ,尽管解决方案可能相同。

向终端服务发送请求时,必须发送一个 header ,指定Content-Type。在此 header 中,您还可以指定action或“肥皂操作”。

$headers = array();
$headers[] = 'Content-Type: application/soap+xml; charset=utf-8; action="[soap action goes here]"';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

就我而言,wsdl列出的内容与您的相同:
<wsdl:operation name="getProducts">
    <soap:operation soapAction=""/>
    <!-- trimmed -->
</wsdl:operation>

首先,我看到soapAction="",因此我在要发送的 header 中设置了action=""。这失败了。进入 header 的正确数据是operation,使其成为action="getProducts"

根据 SoapClient 手册和php using SOAP with a different SoapAction的答案,您的请求应适用于:
$client = new SoapClient( "http://myWebsite.com/services/MyFirstWebService?wsdl", $options );
$result = $client->__soapCall( "getItemField", array('123456') );

您是否曾经忽略发送给$options__soapCall()只是不指定操作(而不是传递空白操作)?
