为什么 WCF 删除了我的回复消息中的 wsa:To header?
Why is the wsa:To header in my reply message removed by WCF?
我有一个带有 IDispatchMessageInspector
和 BeforeSendReply
方法的 WCF 服务,它修改消息的 WS-Addressing headers。这适用于所有 header,除了 wsa:To,它正在从回复中删除...
public void BeforeSendReply(ref Message reply, object correlationState)
{
reply.Headers.To = new Uri("urn:something:something:something"); // Why won't this show up in the response?
reply.Headers.From = new EndpointAddress("urn:blabla:blabla");
reply.Headers.MessageId = MessageIDHelper.CreateNew();
reply.Headers.ReplyTo = new EndpointAddress(Definitions.WSA_REPLYTO_ANONYMOUS);
reply.Headers.Action = Definitions.WSA_ACTION_SOMETHING_SOMETHING;
}
这导致:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>

即使 result.ToString()
(结果 = Message

所以...为什么 wsa:To
header 从我的回复中删除?
TransportBindingElement.ManualAddressing 属性 的文档提供了一些有关寻址行为的信息。 IE。如果 ManuelAddressing 的值设置为 false,则发送通道将通道上配置为 To: addressee 的 EndpointAddress 应用于传出消息。这意味着频道对 To 的值有发言权:header.
现在,BeforeSendReply()
在服务级别修改消息的内容,然后将其交给频道进行传输。因此,如果 ManuelAddressing 的值为 false,通道将在消息中设置自己的 To: 值 header.
只要 ManuelAddressing 的值设置为 true,通道就会假定消息已被寻址并且不会添加任何附加信息。
为了将 ManuelAddressing 设置为 True,可以在 web.config 文件中创建自定义绑定:
<customBinding>
<binding name="customBinding_manualAddressingEnabled">
<textMessageEncoding />
<httpTransport manualAddressing="true"/>
</binding>
</customBinding>
