Web Services 来自Web服务的空响应(WSDL SOAP)

我正在使用Visual Studio 2008 C# Windows应用程序连接到外部公司创建的Web服务。该服务是一个WSDL URL，它是一个基本的SOAP请求和响应。我已将该服务作为服务引用导入。我可以调用该服务，并且没有收到错误，但响应是什么都没有。在Fiddler中监视SOAP请求和响应时，我看到返回了响应，但是好像VS不能解释这个响应。我已经考虑过创建xsd，但是得到一个错误，说已经有一个模式了。所以我完全不知所措。我希望有人能帮助我。如果这个问题以前已经解决了，我很抱歉，但是我找不到任何解决我问题的方法。
提前感谢！
我用来连接服务的代码如下：

ServiceReference1.bpm bbb = new TestingWSDL.ServiceReference1.bpm();

        ServiceReference1.BPMExternalAppServicesV001Client soapClient = new TestingWSDL.ServiceReference1.BPMExternalAppServicesV001Client();

        ServiceReference1.DownloadShipmentDataV001 req = new TestingWSDL.ServiceReference1.DownloadShipmentDataV001();
        ServiceReference1.DownloadShipmentDataV001Response resp = new TestingWSDL.ServiceReference1.DownloadShipmentDataV001Response();

        try
        {

            soapClient.DownloadShipmentDataV001(req,out resp);

        }
        catch(Exception err)
        {
            MessageBox.Show(err.Message);
        }

响应对象中没有任何数据。我不能发布图像，因为我不被允许。
WSDL相当长，如下所示：

感谢您发布由Fiddler收集的响应。实际上，我在WSDL和响应与WSDL数据类型的一致性中发现了不止一个问题。

首次发布：WSDL一致性/完整性

请注意，输入和输出消息分别引用tns:DownloadShipmentDataV001和tns:DownloadShipmentDataV001Response。xmlns:tns="http://schemas.ccc.com/AROPInventory/bpm/external"是消息定义上下文中的相关 prefix：namespace 绑定，因此请求和响应消息元素的全限定名称分别为{http://schemas.ccc.com/AROPInventory/bpm/external}DownloadShipmentDataV001和{http://schemas.ccc.com/AROPInventory/bpm/external}DownloadShipmentDataV001Response。
根据targetNamespace="http://schemas.argility.com/AROPInventory/bpm/external"声明，WSDL文档的types部分中定义的元素的全限定名称为{http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001和{http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001Response。这是一个问题，因为WSDL和任何导入/包含的文档中缺少消息定义中引用的实际类型。
存根生成器在尝试使用WSDL时应报告此问题。
外部公司确实应该纠正这个问题，但是您可以复制WSDL并进行调整，方法是从types部分声明实际元素的名称空间并绑定到一个前缀，然后在消息定义中使用该前缀（缺点是您需要额外的步骤来跟上他们服务定义中的任何更改）：

xmlns:fromtype="http://schemas.argility.com/AROPInventory/bpm/external"
 ...
  <wsdl:message name="DownloadShipmentDataV001Input">
    <wsdl:part name="body" element="fromtype:DownloadShipmentDataV001" />
  </wsdl:message>
  <wsdl:message name="DownloadShipmentDataV001Output">
    <wsdl:part name="body" element="fromtype:DownloadShipmentDataV001Response" />
  </wsdl:message>

第二期：响应消息与架构不匹配

假设WSDL是一致的，并且从类型部分调用了完全限定的数据类型，则响应消息的完全限定元素结构应该如下所示：

{http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001Response
  {http://schemas.argility.com/AROPInventory/bpm/external}Shipments
    {http://schemas.argility.com/AROPInventory/bpm/external}Shipment
      {http://schemas.argility.com/AROPInventory/bpm/external}ShipmentNumber
      {http://schemas.argility.com/AROPInventory/bpm/external}Cartons
        {http://schemas.argility.com/AROPInventory/bpm/external}Carton
 ...

但是，响应消息中的实际结构为：

{http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001Response
  {http://schemas.argility.com/AROPInventory/bpm/external}Shipments
    {http://schemas.argility.com/AROPInventory/bpm/external}ShipmentHeader
      {http://schemas.argility.com/AROPInventory/bpm/external}ShipmentNumber
 ...

请注意，ShipmentHeader从未在WSDL类型部分声明为元素，也不是从其他文档导入的。如果解组器使用WSDL中提供的数据类型定义，它不理解ShipmentHeader或其子元素，因此可能会忽略它们（如您所见）。
此问题的修正是将数据类型模式定义与来自服务的实际响应相匹配。同样，托管服务的外部组织应该修正此问题（他们的服务不符合给定的WSDL），但您可以再次在本地进行调整，并注意额外的步骤使“您的”wsdl与他们的服务保持一致。
我希望这能有所帮助，并回答进一步的问题。

您仍然需要自己解析这个XML文件。
IBM的Remedy软件也有类似的问题。基本上，这是一个糟糕的软件，这种行为应该是意料之中的。即使他们更新代码来匹配，他们也不是从他们正在生成的实际XML文档生成WSDL ......这个问题将继续下去，直到他们改变他们的方法，而你对此没有控制权。

我也遇到过一个类似的问题，空的答案，但在fiddler中，它说的正好相反。我通过删除'System.ServiceModel.XmlSerializerFormatAttribute属性修复了这个问题，并且能够序列化响应。这不是最佳解决方案，但对我来说很有效。
