我在C#客户端创建SOAP头部时遇到了问题。服务器返回了错误信息。
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<s:Header xmlns:s="http://www.w3.org/2003/05/soap-envelope" />
<soap:Body>
<soap:Fault>
<soap:Code>
<soap:Value>soap:MustUnderstand</soap:Value>
</soap:Code>
<soap:Reason>
<soap:Text xml:lang="en">MustUnderstand headers: [{http://www.w3.org/2005/08/addressing}To] are not understood.</soap:Text>
</soap:Reason>
</soap:Fault>
</soap:Body>
</soap:Envelope>
我一直以为我已经用以下代码删除了所有的SOAP头。
internal class CustomMessageInspector : IEndpointBehavior, IClientMessageInspector
{
public object BeforeSendRequest( ref Message request, IClientChannel channel )
{
request.Headers.Clear();
return null;
}
...
}
然而,在app.config中激活System.ServiceModel.MessageLogging后(WCF - 检查发送/接收的消息?),我发现服务器是正确的——看哪里有一个"To"头,并将"mustUnderstand"设置为1:
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">
<s:Header>
<a:To s:mustUnderstand="1">https://ws-single-transactions-int-bp.nmvs.eu:8443/WS_SINGLE_TRANSACTIONS_V1/SinglePackServiceV30</a:To>
</s:Header>
有没有想法如何防止添加此标题?非常感谢。
