我的SoapExtension收到了两次AfterSerialize消息!

soap visual-studio-2010 web-services .net c#

Alfred B. Thordarson · 技术社区 · 14 年前

我正在使用visualstudio2010和C#编写一个需要特殊处理的web服务,我正在通过滚动自己的SoapExtension来解决这个问题。这个SoapExtension当然是实现方法。

处理消息

guy at mofeel.com ,这表明他找到了解决方法 here at experts-exchange.com 但我不会把我的信用卡给你。这是一个原则。有人能帮我吗?

我的 处理消息 方法如下所示:

public override void ProcessMessage(SoapMessage message)
{
    if (message is SoapServerMessage)
    {
        LogFile.WriteLogString(0, "-------------------");
        LogFile.WriteLogString(0, "message.Type:" + message.GetType().ToString());
        LogFile.WriteLogString(0, "message.Stage:" + message.Stage);
        LogFile.WriteLogString(0, "message.Stream.Length:" + message.Stream.Length);
        LogFile.WriteLogString(0, "message.Stream.Position:" + message.Stream.Position);
        LogFile.WriteLogString(0, "message.Exception:" + message.Exception);
        ProcessServerMessage(message);
    }
    else ProcessClientMessage(message);
}

注意每个消息阶段是如何被调用两次的?!?!?

我认为有两种可能。

1-您已经在web.config中配置了soap扩展,并且有一个应用于web方法的自定义SoapExtensionAttribute。

实际上,这将配置SoapExtension两次,因此它将运行一次,这是因为web.config中的配置,而第二次是因为应用于web方法的属性。

2-您实际上已经在web.config中配置了两次soap扩展。
