记录非 .Net SOAP Web 服务的 SOAP 请求和响应

本文关键字：SOAP 请求 求和 响应 Web Net 记录 服务 | 更新日期: 2023-09-27 18:37:22

我在.net应用程序中没有使用.Net SOAP Web服务（ESB服务）。我已经使用添加网络引用添加了参考或服务。

现在，当我调用此服务的任何方法时，我想记录肥皂请求和响应。我想将请求/响应存储在数据库中。

任何人都可以告诉我如何在 c# 中记录 .Net SOAP Web 服务的 soap 请求和响应吗？

记录非 .Net SOAP Web 服务的 SOAP 请求和响应

这段代码来自这篇文章，任何写的代码都不是我的^^

您可以实现一个 SoapExtension，用于记录日志文件的完整请求和响应。然后，您可以在 web.config 中启用 SoapExtension，这样可以轻松打开/关闭以进行调试。这是我找到并修改的供自己使用的示例，在我的情况下，日志记录是由log4net完成的，但您可以将日志方法替换为自己的方法。

public class SoapLoggerExtension : SoapExtension
{
    private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
    private Stream oldStream;
    private Stream newStream;
public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
{
    return null;
}
public override object GetInitializer(Type serviceType)
{
    return null;
}
public override void Initialize(object initializer)
{
}
public override System.IO.Stream ChainStream(System.IO.Stream stream)
{
    oldStream = stream;
    newStream = new MemoryStream();
    return newStream;
}
public override void ProcessMessage(SoapMessage message)
{
    switch (message.Stage)
    {
        case SoapMessageStage.BeforeSerialize:
            break;
        case SoapMessageStage.AfterSerialize:
            Log(message, "AfterSerialize");
                CopyStream(newStream, oldStream);
                newStream.Position = 0;
            break;
            case SoapMessageStage.BeforeDeserialize:
                CopyStream(oldStream, newStream);
                Log(message, "BeforeDeserialize");
            break;
        case SoapMessageStage.AfterDeserialize:
            break;
    }
}
public void Log(SoapMessage message, string stage)
{
    newStream.Position = 0;
    string contents = (message is SoapServerMessage) ? "SoapRequest " : "SoapResponse ";
    contents += stage + ";";
    StreamReader reader = new StreamReader(newStream);
    contents += reader.ReadToEnd();
    newStream.Position = 0;
    log.Debug(contents);
}
void ReturnStream()
{
    CopyAndReverse(newStream, oldStream);
}
void ReceiveStream()
{
    CopyAndReverse(newStream, oldStream);
}
public void ReverseIncomingStream()
{
    ReverseStream(newStream);
}
public void ReverseOutgoingStream()
{
    ReverseStream(newStream);
}
public void ReverseStream(Stream stream)
{
    TextReader tr = new StreamReader(stream);
    string str = tr.ReadToEnd();
    char[] data = str.ToCharArray();
    Array.Reverse(data);
    string strReversed = new string(data);
    TextWriter tw = new StreamWriter(stream);
    stream.Position = 0;
    tw.Write(strReversed);
    tw.Flush();
}
void CopyAndReverse(Stream from, Stream to)
{
    TextReader tr = new StreamReader(from);
    TextWriter tw = new StreamWriter(to);
    string str = tr.ReadToEnd();
    char[] data = str.ToCharArray();
    Array.Reverse(data);
    string strReversed = new string(data);
    tw.Write(strReversed);
    tw.Flush();
}
private void CopyStream(Stream fromStream, Stream toStream)
{
    try
    {
        StreamReader sr = new StreamReader(fromStream);
        StreamWriter sw = new StreamWriter(toStream);
        sw.WriteLine(sr.ReadToEnd());
        sw.Flush();
    }
        catch (Exception ex)
        {
            string message = String.Format("CopyStream failed because: {0}", ex.Message);
            log.Error(message, ex);
        }
    }
}
[AttributeUsage(AttributeTargets.Method)]
public class SoapLoggerExtensionAttribute : SoapExtensionAttribute
{
    private int priority = 1; 
    public override int Priority
    {
        get { return priority; }
        set { priority = value; }
    }
    public override System.Type ExtensionType
    {
        get { return typeof (SoapLoggerExtension); }
    }
}

然后，将以下部分添加到 web.config 中，其中 YourNamespace 和 YourAssembly 指向 SoapExtension 的类和程序集：

<webServices>
  <soapExtensionTypes>
    <add type="YourNamespace.SoapLoggerExtension, YourAssembly" 
       priority="1" group="0" />
  </soapExtensionTypes>
</webServices>

或者试试提琴手。 它将允许您检查请求和响应。值得注意的是，Fiddler同时适用于http和https流量。
