IWcfPolicy-动态添加消息头 [英] IWcfPolicy - add message headers on the fly

问题描述

是否可以即时将标头信息(或查询字符串)添加到wcf请求中? 我一直在像这样混乱IWcfPolicy:

Is it somehow possible to add header info (or querystrings) to a wcf request on the fly? I've been messing around a bit with the IWcfPolicy like this:

    var xmlObjectSerializer = new DataContractSerializer(typeof(string));

    var addressHeader = AddressHeader.CreateAddressHeader("client", "http://tempuri.org/", "someValue", xmlObjectSerializer);

    var endpointAddress = new EndpointAddress(new Uri(url), new AddressHeader[] { addressHeader });

    invocation.ChannelHolder.ChannelFactory.Endpoint.Address = endpointAddress;

    invocation.Proceed();

但是，这不起作用.任何帮助将是非常感谢的.

this does not work however. Any help would be very much apperciated.

推荐答案

好的，这是操作方法:

    using (var scope = new OperationContextScope((IContextChannel) (invocation.ChannelHolder.Channel)))
                {
                    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = new HttpRequestMessageProperty
                        ()
                        {
                            Headers =
                                {
                                    {"client", LicenseManager.Instance.GetCurrentLicense().LicenseKey}
                                }
                        };

                    invocation.Proceed();
                }

此代码进入IWcfPolicy实现的Apply方法. 由于这篇文章找到了解决方案:如何添加自定义每个wcf调用的标头

This code goes into Apply method of the IWcfPolicy implementation. Found solution because of this post: how to add a custom header to every wcf call
