【问题描述】:
我有一个由 Java 客户端调用的 ASP.NET 网络服务。客户端发送一个 SOAP 消息作为输入,但问题是它永远不会到达我的 web 服务方法。我总是得到空输入。我使用 TraceListener 并看到了可能导致问题的警告:
在此上下文中不需要该元素:... 预期元素:http://client.ns.url/:ListenerInput。
这是客户端发送的内容:
<?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;
}
我应该怎么做才能解决这个问题?这是一些跟踪日志:
