我有一个由Java客户端调用的ASP.NET Web服务。客户端发送SOAP消息作为输入,但问题是它永远不会到达我的webservice方法。我总是得到空输入。我使用了TraceListener并看到了这个可能导致问题的警告:
在此背景下不期望该元素:...预期元素:http://client.ns.url/:ListenerInput。
这是客户发送的内容:
<?xml version="1.0" encoding="utf-8"?>
<S:Envelope xmlns:S = "http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:Listener xmlns:ns2 = "http://client.ns.url/">
<ListenerInput>
<errorCode>0</errorCode>
<errorDescription>Success</errorDescription>
<firstPrice xsi:nil = "true" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"/>
</ListenerInput>
</ns2:Listener>
</S:Body>
</S:Envelope>
这是我的网络方法:
[System.Web.Services.WebServiceAttribute(Namespace = "http://client.ns.url/")]
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
[System.Web.Services.WebServiceBindingAttribute(Name = "ListenerWebServicePortSoapBinding", Namespace = "http://client.ns.url/")]
public partial class ListenerService : System.Web.Services.WebService
{
[System.Web.Services.WebMethodAttribute()]
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://client.different.url/services/action/ListenerService/Listener", RequestElementName = "Listener", RequestNamespace = "http://client.ns.url/", ResponseNamespace = "http://client.ns.url/", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("return")]
public ListenerResponse Listener([System.Xml.Serialization.XmlElementAttribute("ListenerInput")]ListenerInput listenerInput)
{
..
这是输入类:
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://client.ns.url")]
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
public partial class ListenerInput
{
public int errorCode;
public string errorDescription;
public float? firstPrice;
}
我该怎么做才能解决这个问题?以下是一些跟踪日志:
Calling IHttpHandler.ProcessRequest
Caller: System.Web.Services.Protocols.SyncSessionlessHandler#47754503::ProcessRequest()
Request Host Address: xxx
Request Url: [POST] http:/my.website/Listener.asmx
..
Calling XmlSerializer [Read Request]
Method: Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer#53218107::Deserialize(System.Web.Services.Protocols.SoapServerProtocol+SoapEnvelopeReader#4153573=.., (null))
Caller: System.Web.Services.Protocols.SoapServerProtocol#51389704::ReadParameters()
...
The element was not expected in this context: <ListenerInput>..</ListenerInput>. Expected elements: http://client.ns.url/:ListenerInput.

Calling ListenerResponse Listener(ListenerInput)

答案 0 :(得分:1)
解决了这个问题。当我应该使用自己的时,我正在使用客户端的命名空间地址。改变了这个:
[System.Web.Services.WebServiceBindingAttribute(Name = "ListenerWebServicePortSoapBinding", Namespace = "http://client.ns.url/")]
public partial class ListenerService : System.Web.Services.WebService
到此:
[System.Web.Services.WebServiceBindingAttribute(Name = "ListenerWebServicePortSoapBinding", Namespace = "http://my.ns.url/")]
public partial class ListenerService : System.Web.Services.WebService
