我正在使用 Visual Studio 2008 C# Windows 应用程序连接到由外部公司创建的 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参考导入。我可以调用该服务，并且没有收到任何错误，但没有任何响应。在 Fiddler 中监视肥皂请求和响应时，我看到一个响应返回，但就好像 VS 无法解释响应一样。我已经研究过创建 xsd，但得到一个错误，指出已经有一个模式。所以我完全不知所措。我希望有人能帮帮忙。如果之前已经解决了这个确切的问题，我深表歉意，但我找不到任何可以解决我的问题的东西。

提前致谢！

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，因为我不允许。

WSDL 很长，如下所示：

感谢您发布 Fiddler 收集的回复。实际上，我在 WSDL 和对 WSDL 数据类型的响应一致性方面看到了不止一个问题。

第一个问题：WSDL 一致性/完整性

请注意，输入和输出消息分别指的是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前缀：命名空间绑定，因此请求和响应消息元素的完全限定名称分别是{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，在 WSDL 文档的 types 部分中定义的元素的完全限定名称是 {http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001和{http://schemas.argility.com/AROPInventory/bpm/external}DownloadShipmentDataV001Response。这是一个问题，因为消息定义中引用的实际类型在 WSDL 和任何导入/包含的文档中都缺失。

存根生成器在尝试使用 WSDL 时应该抱怨这一点。

外部公司应该真正纠正这个问题，但您可以复制 WSDL 并通过从类型部分声明实际元素的命名空间并绑定到前缀，然后在消息定义中使用该前缀（弱点是你有一个额外的步骤来跟上他们的服务定义的任何变化）：

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>

第二个问题：响应消息不匹配架构

假设 WSDL 是一致的，并从类型部分调用了完全限定的数据类型。响应消息的完全限定元素结构将类似于：

{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是：

{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它永远不会在 WSDL 类型部分中声明为元素，也不会从另一个文档中导入。如果 unmarshaller 使用 WSDL 中提供的数据类型定义，它不理解ShipmentHeader或它的子元素，因此可能会忽略这些（如您所见）。

此问题的更正方法是将数据类型架构定义与服务的实际响应相匹配。同样，托管服务的外部组织应该更正此问题（他们的服务不符合给定的 WSDL），但是您可以再次在本地进行调整，但需要注意额外的步骤，以使“您的”wsdl 与他们的服务保持同步。

我希望这会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。基本上它是一个糟糕的软件，这种行为应该是可以预料的。即使他们更新了代码以匹配，他们也不会从他们正在生成的实际 XML 文档中生成 WSDL……这个问题将继续存在，直到他们改变他们的方法并且您无法控制它。
