WCF SOAP 服务：复杂类型属性为空

Question

我一直在尝试使用我提供的 WSDL 设置 WCF WebService 有一段时间了，但我对它无法正常工作感到非常沮丧。我正在构建的服务应该作为某种中间件从客户端接收 SOAP 消息（使用 SAP WSI/PI）并将消息的内容推送到我们的 CMS。它似乎有点工作，但它无法获取复杂类型的值。

我会尽量做到完整，但由于我是一个非常温和的程序员，所以我可能遗漏了有价值的信息或使用了错误的术语。如果您遗漏了一些可以提供帮助的信息，请告诉我。我正在从共享的架构中删除名称空间，以试图隐藏我为其设置服务的客户。

我从客户那里收到了 4 个文件，我试图用它们来构建我的 Web 服务。

1 x Service.wsdl
1 x Serivce.xsd
2 x ExportXMLSchema.xsd

由于我遇到的唯一问题是 ExportXMLSchema.xsd 中定义的复杂类型，因此我将分享这些内容。

我尝试了几种将服务引用导入到我的项目中的方法。将其添加为服务引用并使用 SVCUTIL 创建 class 文件并将其导入到我的项目中（主要是通过覆盖原始服务引用）。当我设置我的服务并将其托管在本地或我们的开发服务器上时，该服务运行良好。但是，我收到的消息（来自客户端或我自己使用 SoapUI 发送的消息）从不包含复杂类型属性。

示例消息包含可用性列表，如下所示：

<n0:Availability>
   <DayOfWeek>MAANDAG</DayOfWeek>
   <DayPart>OCHTEND</DayPart>
</n0:Availability>
<n0:Availability>
   <DayOfWeek>DINSDAG</DayOfWeek>
   <DayPart>OCHTEND</DayPart>
</n0:Availability>
<n0:Availability>
   <DayOfWeek>WOENSDAG</DayOfWeek>
   <DayPart>OCHTEND</DayPart>
</n0:Availability>

(n0 匹配命名空间：http://company.org/mail/hrm/JobPublication)

此消息在 SoapUI 中正确验证，但当我的服务收到消息时，DayOfWeek 和 DayPart 的值为空。我确实收到了三个 "Availbility" 值，所以它部分起作用了。

我尝试使用 /ImportXmlTypes and/or /Serializer:XmlSerializer 等选项通过 SVCUTIL 生成 class 文件，但似乎没有任何效果。 None 在此板上找到的建议似乎对我有用。希望有人能指出我忽略的地方。

提前致谢！

Answer 1

我发现我之前的一个解决方案终于解决了。

最有可能的修复是将 schemaLocation 属性添加到 XSD 和 WSDL 中的导入行。这是必需的，因为我为其提供此服务的公司更改了他们的公司名称，导致命名空间无法访问。我的猜测是，在这种情况下，您需要添加对原始 XSD 的引用，如果是这种情况的话。我有一个本地副本，所以我指向 XSD 的那个版本。这样 Visual Studio 甚至可以为复杂类型创建代理 class。

错误的是我测试它的方式。每次我运行测试请求和调试时，我都在测试我的服务的旧版本，而不是我一直在进行的更新。我猜是菜鸟错误，不幸的是我花了几个小时才意识到这一点。经验教训：确保您有一个可靠的本地测试环境，您可以在其中正确调试。

请让我知道我认为的解决方案是否有误，或者是否还有其他遗漏。可能对我或其他运行遇到类似问题有帮助。
