Question

我正在尝试将图像从silverlight客户端发送到WCF服务。

我有以下要发送的课程

namespace PhotoViewer.DataObjects.Requests
{
    public class SavePhotoRequest
    {
        public Photo Photo { get; set; }
    }
}

namespace PhotoViewer.DataObjects.Entitys
{
    public class Photo
    {
        public Photo() { }

        public Photo(int id, DateTime takeOn, Byte[] photoBinary)
        {
            _iD = id;
            _takenOn = takeOn;
            _photoBinary = photoBinary;
        }

        int _iD;
        DateTime _takenOn;
        Byte[] _photoBinary;

        public int ID { get { return _iD; } set { _iD = value; } }
        public DateTime TakeOn { get { return _takenOn; } set { _takenOn = value; } }
        public Byte[] PhotoBinary { get { return _photoBinary; } set { _photoBinary = value; } }
    }
}

我试图在配置文件中将所有内容设置为max，如下所示

ServiceReference.ClientConfig

<configuration>
  <system.serviceModel>

    <bindings>
      <basicHttpBinding>
        <binding
           name="BasicHttpBinding_IPhotoService"
           closeTimeout="10:00:00"
           openTimeout="10:00:00"
           receiveTimeout="10:00:00"
           sendTimeout="10:00:00"
           maxBufferSize="2147483647"
           maxReceivedMessageSize="2147483647"           
           textEncoding="utf-8" 
           transferMode="Buffered">
          <security mode="None">
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:52715/PhotoService.svc"
                binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_IPhotoService"
                contract="PhotoViewer.Model.ServiceContracts.IPhotoService"
                name="BasicHttpBinding_IPhotoService" />
    </client>
  </system.serviceModel>
</configuration>

的Web.Config

<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
    <httpRuntime maxRequestLength="102400"/>
  </system.web>
  <system.serviceModel>
    <services>
      <service name="PhotoViewer.Service.Implementations.PhotoService"
          behaviorConfiguration="PhotoDebugBehaviors">
        <endpoint contract="PhotoViewer.Service.Interfaces.IPhotoService"
          binding="basicHttpBinding"
          bindingConfiguration="BasicHttpBinding_IPivotService"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="PhotoDebugBehaviors">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
    <bindings>
      <basicHttpBinding>
        <binding
           name="BasicHttpBinding_IPivotService"
           closeTimeout="10:00:00"
           openTimeout="10:00:00"
           receiveTimeout="10:00:00"
           sendTimeout="10:00:00"
           maxBufferSize="2147483647"
           maxReceivedMessageSize="2147483647"
           maxBufferPoolSize="2147483647"
           textEncoding="utf-8" >
          <readerQuotas maxArrayLength="2147483647"
                        maxStringContentLength="2147483647"
                        maxBytesPerRead="2147483647"
                        maxDepth="2147483647"
                        maxNameTableCharCount="2147483647"
                    />
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

但是，只要Bytes数组超过48765，它就不会起作用。我从fiddler得到以下回复。

HTTP / 1.1 400错误请求服务器： ASP.NET Development Server / 10.0.0.0 日期：2011年4月8日星期五21:58:57 GMT X-AspNet-Version：4.0.30319 缓存控制：私有内容长度： 0连接：关闭

我已经阅读了很多文章，其中这似乎只是增加了配置文件中的所有大小，但我已经把这些都放到了最大限度而且无法解决我错过的问题。

修改

这是PhotoService.svc

<%@ ServiceHost Language="C#" 
                Debug="true" 
                Service="PhotoViewer.Service.Implementations.PhotoService" %>

和PhotoService.cs

namespace PhotoViewer.Service.Implementations
{
   public class PhotoService : IPhotoService
    {
        IUnityContainer container;

        public PhotoService()
        {
            SetUnityContainer();
        }

        public SavePhotoResult SavePhoto(SavePhotoRequest request)
        {
            var imageRepository = container.Resolve<IPhotoRepository>();

            imageRepository.SavePhoto(request.Photo);

            container.Resolve<IUnitOfWork>().SubmitChanges();

            return new SavePhotoResult();
        }

        private void SetUnityContainer()
        {
            container = new UnityContainer();
            container.RegisterType<IUnitOfWork, DatabaseUnitOfWork>(new ContainerControlledLifetimeManager());
            container.RegisterType<IRepository<Photo>, Repository<Photo>>(new ContainerControlledLifetimeManager());
            container.RegisterType<IPhotoRepository, PhotoRepository>(new ContainerControlledLifetimeManager());
        }
    }

Answer 1

哦，多么尴尬，似乎我只是一个完全Numpty！

不知怎的，我在项目中得到了一个包含我的服务接口和实现的web.config文件。我一直在更改此配置文件中的所有设置，而不是在asp.net托管项目中使用的配置文件。

一旦我将设置从错误的配置复制到正确的配置文件，它一切正常！是的，有时最好不要燃烧午夜的油
