我收到了客户关于他们的网络服务客户端如何工作的规范。规范是从服务发送和接收的实际SOAP XML消息以及相应的XSD。客户希望我实施符合客户的Web服务。客户端使用axis2 ws-stack编写,我想要做的是在WCF中创建一个Web服务,它将接受客户端发出的请求并返回符合他们期望的XML的响应。在这个问题中,我只会发布与请求相关的XML和XSD,因为如果我可以使用它,响应将以类似的方式进行。
我收到的XML如下:
POST /axis2/services/SampleService HTTP/1.1
Content-Type: text/xml; charset=UTF-8
SOAPAction: "sendCommand"
User-Agent: Axis2
Host: 127.0.0.1:7777
Content-Length: 347
<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<SendCommandRequest xmlns="http://something.org/">
<CMD>
<Station Address="ABC">
<Platform Address="DEF">
<Command>5</Command>
</Platform>
</Station>
</CMD>
</SendCommandRequest>
</soapenv:Body>
</soapenv:Envelope>
这是相应的XSD的样子:
<xsd:complexType name="SendCommandRequestType">
<xsd:sequence>
<xsd:element name="Station">
<xsd:complexType>
<xsd:attribute name="Address" type="xsd:string" use="required" />
<xsd:sequence>
<xsd:element minOccurs="0" maxOccurs="1" name="Platform">
<xsd:complexType>
<xsd:attribute name="Address" type="xsd:string" use="required" />
<xsd:sequence>
<xsd:element name="Command">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="-1"/>
<xsd:enumeration value="0"/>
<xsd:enumeration value="1"/>
<xsd:enumeration value="2"/>
<xsd:enumeration value="3"/>
<xsd:enumeration value="4"/>
<xsd:enumeration value="5"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
<xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
我已经开始用WCF / MessageContract格式编写类型了,但是我在列表等方面遇到了困难,因为它们是双重包装的。
我的MessageContracts看起来像这样:
[MessageContract(WrapperName = "SendCommandRequest", WrapperNamespace = "http://something.org/")]
public class SendCommandRequest
{
[MessageBodyMember(Name="CMD")]
public CMD cmd = new CMD();
}
[MessageContract(IsWrapped=false)]
public class CMD
{
[MessageBodyMember(Name="Station")]
public List<Station> stations = new List<Station>();
}
[MessageContract(IsWrapped=false)]
public class Station
{
[MessageBodyMember]
public List<Platform> platforms = new List<Platform>();
[MessageBodyMember(Name="Address")]
public String Address;
}
[MessageContract(WrapperName = "Platform")]
public class Platform
{
[MessageBodyMember(Name = "Address")]
public String Address;
}
当我使用SoapUI时,我从网络服务获得以下响应:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<SendCommandRequest xmlns="http://ttraflinariawebservice.org/">
<CMD xmlns="http://tempuri.org/" xmlns:a="http://schemas.datacontract.org/2004/07/GeldImport" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<a:stations>
<a:Station>
<a:Address>test</a:Address>
<a:platforms>
<a:Platform>
<a:Address>b</a:Address>
</a:Platform>
</a:platforms>
</a:Station>
</a:stations>
</CMD>
</SendCommandRequest>
</s:Body>
</s:Envelope>
正如您所看到的,它不符合客户期望的XML格式。如何让MessageContract符合客户期望的XML?我不知何故需要使Lists不像它们那样进行双重包装,并且类的属性似乎被添加到类名中。
如果您希望我提供更多信息和代码,我可以这样做。不想用可能与问题无关的事情填写整个帖子。
编辑:
提供的XSD文件格式不正确。为了解决这个问题,我从提供的XML文件中重新生成了一个XSD。然后我使用WSCF.blue工具为XSD生成数据协定代码。
我进行了更改,以便服务合同使用doc litteral格式符合axis2 soap1.1
[XmlSerializerFormat(Use = OperationFormatUse.Literal, Style = OperationFormatStyle.Document, SupportFaults = true)]
[ServiceContract]
public interface MyService
我还更改了操作契约,将System.ServiceModel.Channels.Message作为输入和输出消息,然后使用生成的类(我从XSD生成)手动序列化和反序列化xml。
答案 0 :(得分:4)
您最初尝试的原因是您尝试使用[MessageContract]
类来定义消息的数据合同(架构)。消息契约仅用作最顶层的类(用于定义消息头中的内容以及进入正文的内容)。其他类需要使用您正在使用的任何序列化程序的属性(并且由于您具有XML属性,因此您需要使用XmlSerializer)。下面的代码显示了如何使对象模型符合您提供的模式。您可以使用Fiddler等工具查看它发送的请求。
