不知道如何创建 SOAP <wsse:Security>标题 [英] Clueless about how to create SOAP <wsse:Security> header

问题描述

我几乎没有使用 SOAP 协议的经验.我需要连接到所需标头的服务.我认为这在 Java 中有些标准，但在 C# 中必须手动创建这个头文件.

I'm have near to none experience with SOAP protocol. The service I need to connect to required header. I think this is somewhat standard in Java but in C# one must create this header by hand.

这里有没有人能够连接到类似的服务:已经创建了标头，或者甚至知道一些可以简化标头创建的标准库?你能分享一些代码或参考吗?

Does anyone here been able to connect to similar service: have created the header or maybe even know about some standard library which would simplify creation of header? Can you share some code or references?

我还发现了一个线索，如果使用 WS2005 可能会生成标题，因为它有 WS3 插件.有人可以评论这个吗?快速查看此插件后，我发现与 Security 标头中的字段类似，但仍然无法创建标头.

I also found a clue that maybe header will be generated if using WS2005, because there is WS3 addin for it. Can anybody comment this? After quick look at this addin I found simmilar fields as in Security header, but still wasn't able to create the header.

推荐答案

我们可以通过以下代码解决:

We were able to solve it with the following code:

public class SecurityHeader : System.ServiceModel.Channels.MessageHeader {
    public string userName;
    public string password;

    protected override void OnWriteStartHeader (System.Xml.XmlDictionaryWriter writer, System.ServiceModel.Channels.MessageVersion messageVersion)
    {
        writer.WriteStartElement("wsse", Name, Namespace);
        writer.WriteXmlnsAttribute("wsse", Namespace);
    }

    protected override void OnWriteHeaderContents (System.Xml.XmlDictionaryWriter writer, System.ServiceModel.Channels.MessageVersion messageVersion)
    {
        writer.WriteStartElement("wsse", "UsernameToken", Namespace);

        writer.WriteStartElement("wsse", "Username", Namespace);
        writer.WriteValue(userName);
        writer.WriteEndElement();

        writer.WriteStartElement("wsse", "Password", Namespace);
        writer.WriteValue(password);
        writer.WriteEndElement();

        writer.WriteEndElement();

    }

    public override string Name
    {
        get { return "Security"; }
    }

    public override string Namespace
    {
        get { return "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"; }
    }
}

这写入了 DataPower 框所需的标头.

This wrote the header that was required by the DataPower box.

如何使用 SecurityHeader 类

How to use the class SecurityHeader

    public static void Main(string[] args)
    {

        var webService = new ServiceReference1.MyWebService();
        ....
       webService.Open();


        using (OperationContextScope scope = new OperationContextScope((IContextChannel)webService.InnerChannel))
        {

            var myObjRequest = GetMyObjRequest();

            MessageHeaders messageHeadersElement = OperationContext.Current.OutgoingMessageHeaders;
            messageHeadersElement.Add(SecurityHeader("UserName", "Password"))


             var res = webService.MyServe(myObjRequest);
            Console.WriteLine(res.ToString());
        }
    }
