在DLL中捕捉c#中的SOAP

本文关键字：中的 SOAP DLL | 更新日期: 2023-09-27 18:15:56

我正在构建一个DLL，它应该由我正在构建的其他一些应用程序使用。DLL功能的一部分是记录所有SOAP事务。

我找到了这个关于如何在c#中捕获SOAP事务的解释。https://web.archive.org/web/20160402053148/http://blog.encoresystems.net/articles/how-to-capture-soap-envelopes-when-consuming-a-web-service.aspx

我的问题是，它需要添加以下内容到app.config(链接的页面结束)。

<system.web>
    <webServices>
      <soapExtensionTypes>
        <add type="Encore.PayPal.Soap.TraceExtension, Encore.PayPal.Soap" priority="1" group="0" />
      </soapExtensionTypes>
    </webServices>
  </system.web>

我不希望它成为所有使用我的DLL将此添加到那里的app.config的要求。

是否有一种方法可以在加载DLL时立即执行?

在DLL中捕捉c#中的SOAP

我在MSDN论坛上发现了一个类似的问题:以编程方式注册SOAP扩展

/// <summary>  
/// Programatically registers a <see cref="SoapExtension"/> at runtime with the specified  
/// <see cref="SoapExtensionTypeElement.Priority"/> and <see cref="SoapExtensionTypeElement.Group"/> settings.  
/// </summary>  
/// <param name="type">The <see cref="Type"/> of the <see cref="SoapExtension"/> to register.</param>  
/// <param name="priority">  
/// A value that indicates the relative order in which this SOAP extension runs when multiple SOAP extensions are  
/// specified. Within each group the priority attribute distinguishes the overall relative priority of the SOAP   
/// extension. A lower priority number indicates a higher priority for the SOAP extension. The lowest possible   
/// value for the priority attribute is 1.  
/// </param>  
/// <param name="group">  
/// The relative priority group (e.g. Low or High) in which this SOAP extension runs when multiple SOAP extensions   
/// are configured to run.  
/// </param>  
[ReflectionPermission(SecurityAction.Demand, Unrestricted = true)]  
public static void RegisterSoapExtension(Type type, int priority, PriorityGroup group)  
{  
    if (!type.IsSubclassOf(typeof(SoapExtension)))  
    {  
        throw new ArgumentException("Type must be derived from SoapException.", "type");  
    }  
    if (priority < 1)  
    {  
        throw new ArgumentOutOfRangeException("priority", priority, "Priority must be greater or equal to 1.");  
    }  
    // get the current web services settings...  
    WebServicesSection wss = WebServicesSection.Current;  
    // set SoapExtensionTypes collection to read/write...  
    FieldInfo readOnlyField = typeof(System.Configuration.ConfigurationElementCollection).GetField("bReadOnly", BindingFlags.NonPublic | BindingFlags.Instance);  
    readOnlyField.SetValue(wss.SoapExtensionTypes, false);  
    // inject SoapExtension...  
    wss.SoapExtensionTypes.Add(new SoapExtensionTypeElement(type, priority, group));  
    // set SoapExtensionTypes collection back to readonly and clear modified flags...  
    MethodInfo resetModifiedMethod = typeof(System.Configuration.ConfigurationElement).GetMethod("ResetModified", BindingFlags.NonPublic | BindingFlags.Instance);  
    resetModifiedMethod.Invoke(wss.SoapExtensionTypes, null);  
    MethodInfo setReadOnlyMethod = typeof(System.Configuration.ConfigurationElement).GetMethod("SetReadOnly", BindingFlags.NonPublic | BindingFlags.Instance);  
    setReadOnlyMethod.Invoke(wss.SoapExtensionTypes, null);  
}

你需要在你的客户端/服务器实例化之前调用这个方法。

RegisterSoapExtension(typeof(TraceExtension), 1, PriorityGroup.Low);
PaypalClient cli = new PaypalClient();
