Improve Web Service Interoperability with XML Message Design
我决定将我们现有的消息设计模式导入到新的SOAP服务的WSDL中。
这完全在VS2008和.NET 3.5中,Altova XMLSpy 2009用于架构和wsdl设计。
所以我做了以下事情:
WebServiceBindingAttribute
好的,这是问题:
SOAP请求工作正常,参数的序列化和反序列化工作正常。 问题中的SOAP响应,序列化正在创建错误形成的Xml,并且客户端反序列化无法正常工作。
这是SOAP响应:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetCameraLocationsTableResponse xmlns="http://blah">
<GetCameraLocationsTableResponse Version="1.0rc2">
<Response>
<Success>true</Success>
</Response>
<CameraLocationsTable/>
</GetCameraLocationsTableResponse>
</GetCameraLocationsTableResponse>
</soap:Body>
</soap:Envelope>
注意嵌套的GetCameraLocationsTableResponse
元素,这是错误的。
我已经确认我们的XDocument包装器创建了内部GetCameraLocationsTableResponse
,并且SOAP消息生成器的内部工作中添加了外部GetCameraLocationsTableResponse
它应该是:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetCameraLocationsTableResponse Version="1.0rc2" xmlns="http://blah">
<Response>
<Success>true</Success>
</Response>
<CameraLocationsTable/>
</GetCameraLocationsTableResponse>
</soap:Body>
</soap:Envelope>
所以我很难过,客户端代理代码正确序列化,但服务器代理代码没有。当然,这是我用的服务器代码!
名称已更改为Blah
以保护无辜者。
作为参考,这是我编辑的服务器端代理代码:
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")]
[System.Web.Services.WebServiceBindingAttribute(Name = "Blah", Namespace = "http://Blah", Location = @"http://localhost:57264/wsdl/Blah.wsdl")]
public interface IBlah
{
[System.Web.Services.WebMethodAttribute()]
[SoapLogger]
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[return: System.Xml.Serialization.XmlElementAttribute("GetCameraLocationsTableResponse", Namespace="http://Blah")]
GetCameraLocationsTableResponse GetCameraLocationsTable([System.Xml.Serialization.XmlElementAttribute(Namespace="http://Blah")] NativeCaseInterfaceDelegateRequest NativeCaseInterfaceDelegateRequest);
}
以下是为实现上述Web服务而编写的代码:
[WebService(Namespace = "http://blah")]
public class Blah : WebService, IBlah
{
#region IBlah Members
public GetCameraLocationsTableResponse GetCameraLocationsTable(Blah BlahRequest)
{
return BlahTools.GetCameraLocationsTable(BlahRequest);
}
#endregion
}
使用here中的system.diagnostics开关,我设法提取自动生成的序列化代码:
protected override void Serialize(object objectToSerialize, System.Xml.Serialization.XmlSerializationWriter writer) {
((XmlSerializationWriter1)writer).Write3_Item((object[])objectToSerialize);
}
public void Write3_Item(object[] p) {
WriteStartDocument();
TopLevelElement();
int pLength = p.Length;
if (pLength > 0) {
WriteSerializable((System.Xml.Serialization.IXmlSerializable)((global::blah.GetCameraLocationsTableResponse)p[0]), @"GetCameraLocationsTableResponse", @"http://blah", false, true);
}
}
这是自定义WSDL
<?xml version="1.0" encoding="UTF-8"?>
