Question

我想写一个C＃代码，它在另一台机器上调用（远程）Web服务。为此，我必须在调用的SOAP标头中传递用户名和密码。

我想知道在C＃中实现此代码的示例。

生成的XML应该是：

<env:Header>
    <ns1:Security>
        <ns1:UsernameToken>
            <ns1:Username>XXXXXXXXXXXXXXXX</ns1:Username>
            <ns1:Password>YYYYYYYYYYYYYYYY</ns1:Password>
        </ns1:UsernameToken>
    </ns1:Security>
</env:Header>

有很多方法可以做到这一点。 CustomBinding更灵活，因为它允许更多的控制，因为我建议你。将标头设置为端点是一种简单的方法：

// binding
var binding = new CustomBinding();
binding.Elements.Clear();
binding.Elements.Add(new TextMessageEncodingBindingElement{MessageVersion = MessageVersion.Soap12});
binding.Elements.Add(new HttpTransportBindingElement{MaxReceivedMessageSize = 20000000,});
// endpoint
var endpoint = new EndpointAddress(new Uri(listeningUri), new MySecurityHeader())
var client = new Client(binding, endpoint);
client.SomeMethod();

其中MySecurityHeader是AddressHeader，例如：

    public class MySecurityHeader : AddressHeader
    {
        public override string Name
        {
            get { return "Security"; }
        }

        public override string Namespace
        {
            get { return "<provide the appropiate namespace>"; }
        }

        protected override void OnWriteAddressHeaderContents(System.Xml.XmlDictionaryWriter writer)
        {
            // here you do what you want
            writer.WriteRaw(String.Format(@"
             <UsernameToken xmlns=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"">
             <Username>user</Username>
             <Password Type=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest"">pass</Password>
             </UsernameToken>").Trim());
        }
    }

这是使用IEndpointAdress

的示例

    var customBinding = new CustomBinding();
    customBinding.Elements.Add(new TextMessageEncodingBindingElement { MessageVersion = MessageVersion.Soap12, });
    customBinding.Elements.Add(new HttpTransportBindingElement { MaxReceivedMessageSize = 20000000, });

    var endpointAddres = new EndpointAddress(listeningUri);

    var client = new Client(customBinding, endpointAddres);
    // add my own IEndpointBehavior
    client.ChannelFactory.Endpoint.Behaviors.Add(new CustomBehavior());
    client.SomeMethod();

这是CustomBehavior定义

public class CustomBehavior : IEndpointBehavior
{
    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {}

    public void ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {
        var inspector = new CustomMessageInspector();
        clientRuntime.MessageInspectors.Add(inspector);
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {}

    public void Validate(ServiceEndpoint endpoint)
    {}
}

public class CustomMessageInspector : IClientMessageInspector
{
    public void AfterReceiveReply(ref Message reply, object correlationState)
    {}

    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        request.Headers.Add(new MyMessageHeader());
        return null;
    }
}

public class MyMessageHeader : MessageHeader
{

    protected override void OnWriteHeaderContents(XmlDictionaryWriter writer, MessageVersion messageVersion)
    {
        writer.WriteRaw(String.Format(@"
        <UsernameToken xmlns=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"">
        <Username>user</Username>
        <Password Type=""http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest"">pass</Password>
        </UsernameToken>").Trim());
    }

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

    public override string Namespace
    {
        get { return "MyHeaderNamespace"; }
    }
}

请注意，您在发送请求之前以及收到回复后都有控制权我希望这能解决你的问题，如果你遇到一些问题，请问我。
