在C#中,要记录所有原始SOAP输入和输出,可以使用自定义的SoapExtension类。以下是一个示例:
using System;
using System.IO;
using System.Web.Services.Protocols;
using System.Xml;
public class LoggingSoapExtension : SoapExtension
{
private Stream _originalStream;
private Stream _logStream;
public override Stream ChainStream(Stream stream)
{
_originalStream = stream;
_logStream = new MemoryStream();
return _logStream;
}
public override void ProcessMessage(SoapMessage message)
{
switch (message.Stage)
{
case SoapMessageStage.BeforeSerialize:
break;
case SoapMessageStage.AfterSerialize:
LogSoapMessage("Output", _logStream);
_logStream.Position = 0;
CopyStream(_logStream, _originalStream);
break;
case SoapMessageStage.BeforeDeserialize:
LogSoapMessage("Input", _originalStream);
break;
case SoapMessageStage.AfterDeserialize:
break;
}
}
private void LogSoapMessage(string direction, Stream stream)
{
stream.Position = 0;
var reader = new StreamReader(stream);
var soapMessage = reader.ReadToEnd();
Console.WriteLine($"SOAP {direction} message:");
Console.WriteLine(soapMessage);
}
private void CopyStream(Stream fromStream, Stream toStream)
{
var buffer = new byte[4096];
int bytesRead;
do
{
bytesRead = fromStream.Read(buffer, 0, buffer.Length);
toStream.Write(buffer, 0, bytesRead);
} while (bytesRead > 0);
}
}
<system.web>
<webServices>
<soapExtensionTypes>
<add type="LoggingSoapExtension" priority="1" group="0" />
</soapExtensionTypes>
</webServices>
</system.web>
</configuration>
现在,每次调用Web服务时,所有原始SOAP输入和输出都将被记录在控制台中。
