我有一个带有IDispatchMessageInspector
和BeforeSendReply
方法的WCF服务,该方法修改了消息的WS-Addressing标头。这适用于所有标题,除了wsa:To,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>
<a:Action s:mustUnderstand="1">http://xxx.xx/xxx/Messages/1/Send</a:Action>
<a:RelatesTo>SOME_ID_WHATEVER</a:RelatesTo>
<a:From>
<a:Address>urn:xxx.xx:xxx:xxx</a:Address>
</a:From>
<a:MessageID>urn:uuid:083b5fb7-ff45-4944-b881-b4c590577408</a:MessageID>
<a:ReplyTo>
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
</s:Header>
...
</s:Envelope>
即使result.ToString()
(结果= Message
类型)给了我:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>
<a:Action s:mustUnderstand="1">http://xxx.xx/xxx/Messages/1/Send</a:Action>
<a:RelatesTo>SOME_ID_WHATEVER</a:RelatesTo>
<a:To s:mustUnderstand="1">urn:xxx.xx:xxx:xxx<a:To>
<a:From>
<a:Address>urn:xxx.xx:xxx:xxx</a:Address>
</a:From>
<a:MessageID>urn:uuid:083b5fb7-ff45-4944-b881-b4c590577408</a:MessageID>
<a:ReplyTo>
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
</s:Header>
...
</s:Envelope>
那么......为什么wsa:To
标题会从我的回复中删除?
答案 0 :(得分:1)
TransportBindingElement.ManualAddressing属性的文档提供了有关寻址行为的一些信息。即如果ManuelAddressing的值设置为false,则发送通道将在通道上配置为To:addressee的EndpointAddress应用于传出消息。这意味着该频道在To:标题的值中具有发言权。
现在,BeforeSendReply()
在将消息传递到通道进行传输之前,在服务级别修改消息的内容。因此,如果ManuelAddressing的值为false,则通道将在邮件头中设置自己的To:值。
每当ManuelAddressing的值设置为true时,通道会假定消息已被解决,并且不会添加任何其他信息。 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>
