Question

是否可以动态地将标题信息（或查询字符串）添加到wcf请求中？我一直在用IWcfPolicy搞砸了这个：

    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();

然而，这不起作用。任何帮助都会非常适合。

好的，所以这里是如何做到的：

    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：how to add a custom header to every wcf call
