WebRequest within Soap

本文关键字：Soap within WebRequest | 更新日期: 2023-09-27 18:36:55

我希望有人能帮助我，我已经有一段时间没有用C#编程了。我相信答案会很简单，但我就是无法理解它。

我

有以下内容，我称之为System.Web.Services.Protocols.SoapHttpClientProtocol。我只包括了我打的众多电话中的一个。

public partial class ExchangeService : System.Web.Services.Protocols.SoapHttpClientProtocol   {
//Lots of code using Soap 
    [System.Web.Services.Protocols.SoapDocumentMethodAttribute("getDetailsLite", RequestNamespace="http://www.MySite.com/ExchangeService/", ResponseNamespace=" http://www.MySite.com/ExchangeService/", ", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
    [return: System.Xml.Serialization.XmlElementAttribute("Result", IsNullable=true)]
    public GetDetailsLiteResp getDetailsLite(getDetailsLiteReq request) {
        object[] results = this.Invoke("getDetailsLite", new object[] {
                    request});
        return ((getDetailsLiteResp)(results[0]));
    }
    public void getDetailsLiteAsync(getDetailsLiteReq request) {
        this. getDetailsLiteAsync(request, null);
    }
    public void getDetailsLiteAsync (getDetailsLiteReq request, object userState) {
        if ((this.getDetailsLiteOperationCompleted == null)) {
            this.getDetailsLiteOperationCompleted = new System.Threading.SendOrPostCallback(this.OngetDetailsLiteOperationCompleted);
        }
        this.InvokeAsync("getDetailsLite", new object[] {
                    request}, this. getDetailsLiteOperationCompleted, userState);
    }
}

我想覆盖 SoapHttpClientProtocol 调用的 WebRequest。SoapHttpClientProtocol看起来像这样（我相信它是从System.Web.Services.dll调用的）

namespace System.Web.Services.Protocols  {
    public class SoapHttpClientProtocol : HttpWebClientProtocol    {
    public SoapHttpClientProtocol();
    public SoapProtocolVersion SoapVersion { get; set; }
    protected IAsyncResult BeginInvoke(string methodName, object[] parameters, AsyncCallback callback, object asyncState);
    public void Discover();
    protected object[] EndInvoke(IAsyncResult asyncResult);
    protected virtual XmlReader GetReaderForMessage(SoapClientMessage message, int bufferSize);
    //This line is the one i am talking about
    protected override WebRequest GetWebRequest(Uri uri);
    protected virtual XmlWriter GetWriterForMessage(SoapClientMessage message, int bufferSize);
    protected object[] Invoke(string methodName, object[] parameters);
    protected void InvokeAsync(string methodName, object[] parameters, SendOrPostCallback callback);
    protected void InvokeAsync(string methodName, object[] parameters, SendOrPostCallback callback, object userState);
    }
}

我需要保护覆盖WebRequest GetWebRequest（Uri uri）看起来像这样：

protected override WebRequest GetWebRequest(Uri uri)  {
    HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);
    webRequest.KeepAlive = false;
    webRequest.ProtocolVersion=HttpVersion.Version10;
    return webRequest;
}

有谁知道我会怎么做？我很乐意直接在 SoapHttpClientProtocol 中编辑它，我 99% 确定我无论如何都不应该这样做。

感谢您提供的任何帮助

WebRequest within Soap

由于ExchangeService是分部类，因此您可以创建另一个文件，该文件添加到ExchangeService声明中，并为 GetWebRequest 声明合适的覆盖。 这将允许您为 ExchangeService 编写自定义功能，同时在 WSDL 更改时仍然可以更新它。

有关详细信息，请参阅 MSDN 文章分部类和方法（C# 编程指南）。

subclass it？GetWebRequest 在根类 WebClientProtocol 中标记为虚拟，因此您可以重写该方法。

public class MyHttpProtocol : SoapHttpClientProtocol  
{
    public override WebRequest GetWebRequest(Uri uri)
    {
        // Base request:
        WebRequest request = base.GetWebRequest(uri);
        // You code goes here...
        // Return...
        return request;
    }
}

然后根据需要在服务类中使用 MyHttpProtocol。
