我正在尝试记录由我开发的控制台应用程序和特定第三方远程SOAP Web服务之间的请求和响应(原始XML SOAP信封)以进行审计目的,并且我找不到方法来实现它。
理想情况下,我想要做的是获取请求。
并将它们保存在数据库中。
到目前为止,我在网络上找到的每个教程都归结为两种方法:SoapExtension方法和跟踪方法。
SoapExtension方法
SoapExtension方法基于使用SOAP扩展修改SOAP消息指南,在此方法中,您创建一个从SoapExtension继承的类,并将其钩入应用程序的配置中,该类的ProcessMessage方法将允许您拦截SOAP消息。
这是一个从SoapExtension继承的类的示例:
这种方法的问题在于它似乎只适用于Web应用程序,在控制台应用程序中实现它没有任何结果。
跟踪方法
跟踪方法基于 配置消息日志记录 指南,使用此方法可以为应用程序中的每个SOAP/WCF通信启用.NET跟踪,并将日志转储到某个地方(有关配置的更多信息,请参见 推荐的跟踪和消息日志记录设置)。
以下是跟踪配置示例:
这里的
理想情况下,我想要做的是获取请求。
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
<soapenv:Header/>
<soapenv:Body>
<tem:SayHello>
<tem:name>Albireo</tem:name>
</tem:SayHello>
</soapenv:Body>
</soapenv:Envelope>
和响应
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<SayHelloResponse xmlns="http://tempuri.org/">
<SayHelloResult>Hello, Albireo.</SayHelloResult>
</SayHelloResponse>
</s:Body>
</s:Envelope>

namespace Playground.Client
{
using System;
using System.Web.Services.Protocols;
public class SoapLogger : SoapExtension
{
public override object GetInitializer(System.Type serviceType)
{
throw new NotImplementedException();
}
public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
{
throw new NotImplementedException();
}
public override void Initialize(object initializer)
{
throw new NotImplementedException();
}
public override void ProcessMessage(SoapMessage message)
{
throw new NotImplementedException();
}
}
}
这是它在配置中的连线方式:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0"
sku=".NETFramework,Version=v4.5" />

由于文件太大,ServiceModel.svclog和MessageLogging.svclog的内容可以在GitHub的Gist中找到。
这种方法的问题是它记录了应用程序中每个 SOAP/WCF 消息,并且似乎生成的日志并不真正有用,其中包含大量信息,我无法理解如何过滤我感兴趣的内容,唯一实用的阅读方式似乎是使用Microsoft的Service Trace Viewer。
我也尝试添加自定义TraceListener:
namespace Playground.Client
{
using System;
using System.Diagnostics;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Linq;
public class CustomTraceListener : TraceListener
{
public override void Write(string message)
{
File.AppendAllLines("CustomTraceListener.txt", new[] { message });
}
public override void WriteLine(string message)
{
message = this.FormatXml(message);
File.AppendAllLines("CustomTraceListener.txt", new[] { message });
}
private string FormatXml(string message)
{
using (var stringWriter = new StringWriter())
{
var xmlWriterSettings = new XmlWriterSettings();
xmlWriterSettings.Encoding = Encoding.UTF8;
xmlWriterSettings.Indent = true;
xmlWriterSettings.OmitXmlDeclaration = true;
using (var xmlTextWriter = XmlWriter.Create(stringWriter, xmlWriterSettings))
{
XDocument.Parse(message).Save(xmlTextWriter);
}
return Convert.ToString(stringWriter);
}
}
}
}
但即使它允许我拦截消息,它也不会保存任何元数据:

有了这些信息,无法重建请求/响应流,因为所有消息都混在一起。
将它们与本地XmlWriterTraceListener生成的*.svclog进行比较:

标签建立了每个请求和响应之间的关系,允许开发人员重建整个会话。是否有办法实现我想做的事情?
