包含无法识别的 http 正文格式值“Xml”

Question

关于堆栈溢出有很多类似的问题，但没有一个帮助我制定解决方案。

下面的问题是最接近的，但我无法让它工作，当我尝试实现它时我的其他服务停止工作。

WCF input huge XML as Stream with Content-Type: xml/text

错误：操作“IncomingXML”的传入消息（带有命名空间的合同...）包含无法识别的 http 正文格式值“Xml”。预期的正文格式值为“原始”。这可能是因为尚未在绑定上配置 WebContentTypeMapper。详情请参阅 WebContentTypeMapper 的文档。

基本上我需要这个并且只有这个 Web 服务才能接受“application/xml”。目前它只接受“raw”，当调用设置了“application/xml”时服务会失败。

问题是两部分，一是允许服务接受 xml，二是不影响其他 Web 服务。这是唯一接受传入 xml 的服务。

有人有什么建议吗？如果我不能在不中断其他网络服务的情况下让它工作。

合同

[OperationContract]
[WebInvoke(Method = "POST")]
void IncomingXML(Stream xml);

服务

public void IncomingXML(Stream xml)
{
}

这篇博文有解决办法：http://kimcuhoang.blogspot.be/2011/04/solving-raw-issue-with-wcf-and-content_13.html

基本上你必须覆盖默认的网络消息编码

创建自定义映射器：

public class RawContentTypeMapper : WebContentTypeMapper
{
    public override WebContentFormat GetMessageFormatForContentType(string contentType)
    {
        if (contentType.Contains("text/xml") || contentType.Contains("application/xml"))
        {
            return WebContentFormat.Raw;
        }
        else
        {
            return WebContentFormat.Default;
        }
    }
}

然后在绑定配置中引用它：

<service behaviorConfiguration="NotificationServiceBehavior" name="AtlanticGateway.GatewayComponent.Services.NotificationService">

<endpoint behaviorConfiguration="web" binding="customBinding" bindingConfiguration="RawReceiveCapable" contract="AtlanticGateway.GatewayComponent.Message.INotificationService" />


<bindings>
 <customBinding>
   <binding name="RawReceiveCapable">

     <webMessageEncoding  webContentTypeMapperType="AtlanticGateway.GatewayComponent.RawContentTypeMapper, AtlanticGateway.GatewayComponent, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />

     <httpTransport manualAddressing="true" maxReceivedMessageSize="524288000" transferMode="Streamed" />
     ...
