WCF WSDL SOAP消息头的所有操作 [英] WCF WSDL Soap Header on all operations

问题描述

通过定义一个实现IContactBehavior和IWsdlExportExtension和设置您的服务合同上属性的属性，你可以轻松地添加 SOAP头到您的WSDL （见的 HTTP：//wcfextras.$c$cplex.com/ 获得更多信息）

By defining an attribute that implements IContactBehavior and IWsdlExportExtension and set that attribute on your service contract, you can easily add Soap Headers to your wsdl (see http://wcfextras.codeplex.com/ for more information)

但现在我需要设置在所有Operationcontracts的WSDL SOAP头合约，这次我不能设置一个属性。

But now I need to set a Soap Header contract in the wsdl on all Operationcontracts and this time I cannot set an attribute.

继code（从IWsdlExportExtension.ExportEndPoint调用）不起作用，但是从SoapHeaderAttributes（即执行一个IWsdlExportExtension.ExportContract）

Following code (called from IWsdlExportExtension.ExportEndPoint) doesn't work, but does work when called from the SoapHeaderAttributes (that executes an IWsdlExportExtension.ExportContract)

foreach (OperationDescription operationDescription in context.ContractConversionContext.Contract.Operations)
{
   AddSoapHeader(operationDescription, "SomeHeaderObject", typeof(SomeHeaderObject), SoapHeaderDirection.InOut);                    
}

internal static void AddSoapHeader(OperationDescription operationDescription, string name, Type type, SoapHeaderDirection direction)
{
	MessageHeaderDescription header = GetMessageHeader(name, type);
	bool input = ((direction & SoapHeaderDirection.In) == SoapHeaderDirection.In);
	bool output = ((direction & SoapHeaderDirection.Out) == SoapHeaderDirection.Out);

	foreach (MessageDescription msgDescription in operationDescription.Messages)
	{
		if ((msgDescription.Direction == MessageDirection.Input && input) ||
			(msgDescription.Direction == MessageDirection.Output && output))
			msgDescription.Headers.Add(header);
	}
}

internal static MessageHeaderDescription GetMessageHeader(string name, Type type)
{
	string headerNamespace = SoapHeaderHelper.GetNamespace(type);
	MessageHeaderDescription messageHeaderDescription = new MessageHeaderDescription(name, headerNamespace);
	messageHeaderDescription.Type = type;
	return messageHeaderDescription;
}

任何人有一个想法如何应用此code上的所有操作（不使用属性），并通过这样做，加上头的合同的WSDL？

Anyone has an idea how to apply this code on all operations (without using attributes) and by doing this, adding the contract of the header to the wsdl ?

推荐答案

该IEndpointBehavior具有以下接口：

The IEndpointBehavior has the following interface:

ApplyDispatchBehavior(ServiceEndpoint endPoint, EndPointDispatcher endpointDispatcher);

您可以通过遍历在ApplyDispatchBehavior的endpoint.Contract.Operations SOAP头添加到WSDL中的操作。

You can add Soap Headers to the wsdl for operations by iterating over the endpoint.Contract.Operations in the ApplyDispatchBehavior.

在这里，你必须为我工作的完整解决方案：

Here you have the complete solution that worked for me:

void IEndpointBehavior.ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
    foreach (OperationDescription operationDescription in endpoint.Contract.Operations)
    {
        foreach (MessageDescription msgDescription in operationDescription.Messages)
        {
            AddSoapHeader(operationDescription, "SomeHeaderObject", typeof(SomeHeaderObject), SoapHeaderDirection.InOut);
        }
    }
}

internal static void AddSoapHeader(OperationDescription operationDescription, string name, Type type, SoapHeaderDirection direction)
{
    MessageHeaderDescription header = GetMessageHeader(name, type);
    bool input = ((direction & SoapHeaderDirection.In) == SoapHeaderDirection.In);
    bool output = ((direction & SoapHeaderDirection.Out) == SoapHeaderDirection.Out);

    foreach (MessageDescription msgDescription in operationDescription.Messages)
    {
            if ((msgDescription.Direction == MessageDirection.Input && input) ||
                    (msgDescription.Direction == MessageDirection.Output && output))
                    msgDescription.Headers.Add(header);
    }
}

internal static MessageHeaderDescription GetMessageHeader(string name, Type type)
{
    string headerNamespace = SoapHeaderHelper.GetNamespace(type);
    MessageHeaderDescription messageHeaderDescription = new MessageHeaderDescription(name, headerNamespace);
    messageHeaderDescription.Type = type;
    return messageHeaderDescription;
}

该SoapHeaderHelper可以在 WcfExtras 。
