[英]Prevent “To” SOAP header being added
I'm have a problem with a SOAP header created in my C# client. 我在C#客户端中创建的SOAP标头存在问题。 The server is sending back the error 服务器正在发回错误
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<s:Header xmlns:s="http://www.w3.org/2003/05/soap-envelope" />
<soap:Body>
<soap:Fault>
<soap:Code>
<soap:Value>soap:MustUnderstand</soap:Value>
</soap:Code>
<soap:Reason>
<soap:Text xml:lang="en">MustUnderstand headers: [{http://www.w3.org/2005/08/addressing}To] are not understood.</soap:Text>
</soap:Reason>
</soap:Fault>
</soap:Body>
</soap:Envelope>
I have been under the impression that I have been removing all SOAP headers with the following code. 我一直以为我已使用以下代码删除了所有SOAP标头。
internal class CustomMessageInspector : IEndpointBehavior, IClientMessageInspector
{
public object BeforeSendRequest( ref Message request, IClientChannel channel )
{
request.Headers.Clear();
return null;
}
...
}
However, after activating System.ServiceModel.MessageLogging in the app.config, ( WCF - Inspect the messages being sent/received? ), I see that the server is correct - lo and behold there is a "To" header with "mustUnderstand" set to 1 : 但是,在app.config中激活System.ServiceModel.MessageLogging( WCF-检查正在发送/接收的消息? )之后,我看到服务器是正确的-瞧,那里有一个“ To”标头,标有“ mustUnderstand”设置为1:
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">
<s:Header>
<a:To s:mustUnderstand="1">https://ws-single-transactions-int-bp.nmvs.eu:8443/WS_SINGLE_TRANSACTIONS_V1/SinglePackServiceV30</a:To>
</s:Header>
Any thoughts how I can prevent this header from being added? 有什么想法如何防止添加此标头?
Many thanks. 非常感谢。
In case it helps anybody else, I have found a solution. 万一它对其他人有帮助,我已经找到了解决方案。 In fact Nicolas Giannone provided all the necessary code here WSHttpBinding in .NetStandard or .NET core . 实际上,Nicolas Giannone 在.NetStandard或.NET core中提供了WSHttpBinding所需的所有必需代码。 What we can do is to replace the WSHttpBinding with a custom binding based on the WSHttpBinding, and then replace the TextMessageEncodingBindingElement with one with no addressing. 我们可以做的是用基于WSHttpBinding的自定义绑定替换WSHttpBinding,然后将TextMessageEncodingBindingElement替换为无地址的绑定。 Here's the code : 这是代码:
string endPoint = myConfig.SinglePackServicesEndPoint;
//Defines a secure binding with certificate authentication
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
// create a new binding based on the existing binding
var customTransportSecurityBinding = new CustomBinding( binding );
// locate the TextMessageEncodingBindingElement - that's the party guilty of the inclusion of the "To"
var ele = customTransportSecurityBinding.Elements.FirstOrDefault( x=>x is TextMessageEncodingBindingElement );
if( ele != null )
{
// and replace it with a version with no addressing
// replace {Soap12 (http://www.w3.org/2003/05/soap-envelope) Addressing10 (http://www.w3.org/2005/08/addressing)}
// with {Soap12 (http://www.w3.org/2003/05/soap-envelope) AddressingNone (http://schemas.microsoft.com/ws/2005/05/addressing/none)}
int index = customTransportSecurityBinding.Elements.IndexOf( ele );
var textBindingElement = new TextMessageEncodingBindingElement
{
MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None)
};
customTransportSecurityBinding.Elements[index] = textBindingElement;
}
