相关疑难解决方法(0)

我正在尝试使用带有消息合同的WCF流,因为我需要在流本身旁边添加其他参数.

基本上我正在创建一个文件上传和下载服务,顶部还有一些额外的逻辑.

不幸的是,当我尝试从浏览器点击服务以检查一切正常时,我收到以下错误:

'/'应用程序中的服务器错误.合同'IFileTransferService'中的"UploadFile"操作使用具有SOAP头的MessageContract.None MessageVersion不支持SOAP标头.

不幸的是谷歌搜索它并没有产生任何帮助我的重要结果.你们能帮助我吗？这里是服务的细节(我已经删除了下载部分,因为空间的原因).

[ServiceContract(Namespace = "http://www.acme.org/2009/04")]
public interface IFileTransferService
{
    [OperationContract(Action = "UploadFile")]
    void UploadFile(FileUploadMessage request);
}

[MessageContract]
public class FileUploadMessage
{
    [MessageHeader(MustUnderstand = true)]
    public FileMetaData Metadata { get; set; }

    [MessageBodyMember(Order = 1)]
    public Stream FileByteStream { get; set; }
}

[DataContract(Namespace = "http://schemas.acme.org/2009/04")]
public class FileMetaData
{
    [DataMember(Name="FileType", Order=0, IsRequired=true)]
    public FileTypeEnum fileType;

    [DataMember(Name="localFilename", Order=1, IsRequired=false)]
    public string localFileName;

    [DataMember(Name = "remoteFilename", Order = 2, IsRequired = false)]
    public string remoteFileName;
}

我试图使用basichttpbinding和customhttp绑定,但效果不佳:

<customBinding> …

我感兴趣地阅读了以下帖子,因为它是我遇到的问题的完全复制品(并且让我疯狂)"对于操作中的请求,UploadFile是一个流,操作必须有一个类型为Stream的参数." - http://social.msdn.microsoft.com/Forums/en/wcf/thread/80cd26eb-b7a6-4db6-9e6e-ba65b3095267

我几乎遵循了我找到的所有代码/示例,但仍无法解决此错误 - http://blogs.msdn.com/b/carlosfigueira/archive/2008/04/17/wcf-raw-programming-model -接收-任意data.aspx

我想要实现的是使用标准的文件名/流参数从Android设备发布一个图像(jpeg/png).很可能它是一个简单的东西我错误配置,误解或遗漏但我需要有一个概念证明的解决方案.

 public interface IConXServer
    {
    [OperationContract]
    [WebInvoke(UriTemplate = "UploadImage({fileName})", Method="POST")]
    void UploadImage(string fileName, Stream imageStream);
    }

 public class ConXWCFServer : IConXServer
    {
    public void UploadImage(string fileName, Stream imageStream)
       {
       //implement image save
       }
    }
