我是这个肥皂消息和东西的新手，我在使用WebService时遇到了一些麻烦，我使用WSDL.exe创建了一个类，我遇到的第一个问题是执行命令时，它创建了一个参数var [] []我必须替换单个var []（数组）。
然后它成功编译，现在我有一些问题，我不知道如何解决它：
我发送的请求就是这个：

我需要切换：
1）在信封节点中，我需要添加一个新属性：
xmlns:neon="http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl"
2）在emitir节点上，我需要它<neon:emitir></neon:emitir>而不是常规<emitir>
当我这样做时，一切都像魅力，就像我说我用wsdl.exe工具创建了类，这是我正在使用的代码：
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace = "http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl", ResponseNamespace = "http://neon.stoconsulting.com/NeonEmisionWS/NeonEmisionWS?wsdl", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("RespuestaWS", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
[WebServiceSOAPExtension]
public respuestaWS emitirWS(comprobante comprobante)
{
object[] results = this.Invoke("emitirWS", new object[] {
comprobante});
return ((respuestaWS)(results[0]));
}
谢谢，我不知道从哪里开始。
答案 0 :(得分：0)
对于那些正在试图做这样的事情并且你不知道的所有人来说，我最后做了一些我不推荐的令人讨厌的东西，但是如果你像我一样被卡住而你却没有线索从哪里开始“正确”的方式，你可以这样做：
首先，您需要创建一个扩展SoapExtension的类，如下所示：
namespace SoapExentender
{
class WebServiceSOAPExtension : SoapExtension
{
Stream oldStream;
Stream newStream;
string filename;
public override Stream ChainStream(Stream stream)
{
oldStream = stream;
newStream = new MemoryStream();
return newStream;
}
// When the SOAP extension is accessed for the first time, the XML Web service method it is applied to is accessed to store the file name passed in,
//using the corresponding SoapExtensionAttribute.
public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
{
return null;
}
// The SOAP extension was configured to run using a configuration file instead of an attribute applied to a specific XML Web service method.
public override object GetInitializer(Type WebServiceType)
{
return null;
}
// Receive the file name stored by GetInitializer and store it in a member variable for this specific instance.
public override void Initialize(object initializer)
{
filename = ConfigurationManager.AppSettings["STOFacturacionDLL"].ToString();
}
// If the SoapMessageStage is such that the SoapRequest or SoapResponse is still in the SOAP format to be sent or received, save it out to a file.
public override void ProcessMessage(SoapMessage message)
{
switch (message.Stage)
{
case SoapMessageStage.BeforeSerialize:
break;
case SoapMessageStage.AfterSerialize: //el xml serializado de salida
WriteOutput((SoapClientMessage)message);
break;
case SoapMessageStage.BeforeDeserialize:
WriteInput((SoapClientMessage)message);
break;
case SoapMessageStage.AfterDeserialize:
break;
default:
throw new Exception("Stage inválido");
}
}
// Write the contents of the outgoing SOAP message to the log file.
public void WriteOutput(SoapClientMessage message)
{
newStream.Position = 0;
FileStream fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
StreamWriter myStreamWriter = new StreamWriter(fs);
myStreamWriter.WriteLine("================================== Fecha del request: " + DateTime.Now);
// Print to the log file the request header field for SoapAction header.
myStreamWriter.WriteLine(@"La acción SOAP del 'header' Http request es: " + message.Action);
// Print to the log file the method invoked by the client.
myStreamWriter.WriteLine("El metodo llamado fue: " + message.MethodInfo.Name);
// Print to the log file if the method invoked is OneWay.
if (message.OneWay)
myStreamWriter.WriteLine("El cliente no espera a que se termine el proceso (no es de un solo sentido)");
else
myStreamWriter.WriteLine("El cliente espera a que se termine el proceso");
// Print to the log file the URL of the site that provides implementation of the method.
myStreamWriter.WriteLine("La URL solicitada fue: " + message.Url);
myStreamWriter.WriteLine("el contenido del request/response del ---- <soap:envelope> ---- es : ");
myStreamWriter.Flush();
Copy(newStream, fs);
myStreamWriter.Close();
//replace custom text
string stringRequest = "";
try
{
newStream.Position = 0;
MemoryStream RequestStream = new MemoryStream();
Copy(newStream, RequestStream);
RequestStream.Position = 0;
byte[] bytesRequestStream = ReadFully(RequestStream);
stringRequest = System.Text.Encoding.UTF8.GetString(bytesRequestStream);
stringRequest = replaceText(stringRequest, "<ReimprimirReferencia", "<thepanch:ReimprimirReferencia");
int i = 0;
}
catch (Exception exc) { }
newStream.Position = 0;
//replace the original stream, with the custom stream
Copy(ConvertStringToStream(stringRequest), oldStream);
}
private string replaceText(string MainString, string SearchString, string ReplaceWith)
{
MainString = MainString.Replace(SearchString, ReplaceWith);
return MainString;
}
private MemoryStream ConvertStringToStream(string RequestString)
{
byte[] byteArray = Encoding.UTF8.GetBytes(RequestString);
MemoryStream stream = new MemoryStream(byteArray);
stream.Position = 0;
return stream;
}
private byte[] ReadFully(Stream input)
{
using (MemoryStream ms = new MemoryStream())
{
input.CopyTo(ms);
return ms.ToArray();
}
}
public void WriteInput(SoapMessage message)
{
Copy(oldStream, newStream);
FileStream fs = new FileStream(filename, FileMode.Append, FileAccess.Write);
StreamWriter w = new StreamWriter(fs);
string soapString = (message is SoapServerMessage) ? "SoapRequest" : "SoapResponse";
w.WriteLine("----------" + soapString + " at " + DateTime.Now);
w.Flush();
newStream.Position = 0;
Copy(newStream, fs);
w.Close();
newStream.Position = 0;
}
void Copy(Stream from, Stream to)
{
TextReader reader = new StreamReader(from);
TextWriter writer = new StreamWriter(to);
writer.WriteLine(reader.ReadToEnd());
writer.Flush();
}
}
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class WebServiceSOAPExtensionAttribute : SoapExtensionAttribute
{
private int priority;
public override Type ExtensionType
{
get { return typeof(WebServiceSOAPExtension); }
}
public override int Priority
{
get { return priority; }
set { priority = value; }
}
}
}
然后在代理的方法上使用自定义属性用自定义流替换实际的Stream，writeOutput方法用于“请求”而writeInput方法用于“响应”，那么你需要使用你的字符串，以满足您的需求，我希望它有所帮助。
正如我在第一行中提到的，这不是正确的方法，但是如果你像我一样不知道从哪里开始，你可以编写自定义的Xml字符串。
