Question

我在配置maxRecievedMessageSite的{{1}}属性时遇到了一些问题。我想创建一个端点来上传潜在的大文件，但是当前（我假设默认）限制是64K。对于图像和大型文档等项目，此限制不起作用。我已经从basicHttpBinding创建了一个新的绑定，但是我一直在堆栈跟踪中得到错误，让我知道我已超出限制。下面我已经包含了我的配置文件，Global.asax文件，我的运营合同和我的服务实现中的相关部分。（一切都非常简单，只是想让它发挥作用）。

配置文件

basicHttpBinding

Global.asax文件

<system.webServer>
  <system.serviceModel>
    <services>
      <!-- CarImage Service Configuration -->
      <service name="CarImageService">

      </service>
    </services>

          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

</system.serviceModel>

运营合同

namespace Mavizon.Mavia.Services
{
    public class Global : HttpApplication
    {
        private string FilePath = ConfigurationManager.AppSettings["ImageFolder"];

        void Application_Start(object sender, EventArgs e)
        {
            if (!Directory.Exists(FilePath))
            {
                Directory.CreateDirectory(FilePath);
            }
            RegisterRoutes();
        }

        private void RegisterRoutes()
        {
            RouteTable.Routes.Add(new ServiceRoute("test", new WebServiceHostFactory(), typeof(CarImageService)));
        }
    }
}

我的（非常）简单的实现类

namespace Mavizon.Mavia.Services.OperationContracts
{
    [ServiceContract]
    public interface ICarImageService
    {
        [OperationContract]
        [FaultContract(typeof(ErrorFault))]
        [WebInvoke(Method = "POST", UriTemplate = "/")]
        void UploadImage(Stream request);
    }
}

**这是我的堆栈跟踪信息**

namespace Mavizon.Mavia.Services.WebServices
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class CarImageService : OperationContracts.ICarImageService
    {
        public void UploadImage(Stream request)
        {

        }
    }
}

非常感谢任何帮助！

Answer 1

两个问题：

您正在使用地址为“”的服务端点的WCF配置，但随后使用代码在“/ test”地址处使用ASP.NET路由来启动服务。您应该只需要将配置地址与要获取的端点配置的路由地址对齐。
您正在使用basicHttpBinding配置服务，但在运行时您指定将使用webHttpBinding（即REST支持）的WebServiceHostFactory。您想将配置更改为webHttpBinding。如果它找到了您的服务的端点，那么接下来会遇到此错误，因为绑定类型会不匹配。

<强>更新

我今天早上意识到＃1是不好的建议。实际上，您无法通过ServiceRoute注册混合/匹配WCF服务/端点配置。因此，您有两种方法可以将特定绑定配置应用于ServiceRoutes：

配置webHttpBinding的默认值。这绝对是最简单的方法，因为它是所有配置，并且不需要对您正在进行的操作进行任何代码更改。请参阅下面的示例。
编写自定义WebServiceHostFactory和WebServiceHost子类，然后覆盖主机的创建并配置所需的特定绑定信息。当你要编写一堆服务项目时，这是一种更好的方法，因为不是所有项目都必须确保应用正确的配置条目，他们可以通过引用共享工厂实现做new MyWebServiceHostFactory()。

默认绑定配置示例：

<system.serviceModel>
    <bindings>
        <webHttpBinding>
            <!-- no name attribute on a binding means it's the default for the biding type -->
            <binding transferMode="Streamed"
                     maxReceivedMessageSize="67108864">
               <!-- other config here -->
            </binding>
        </webHttpBinding>
    </bindings>
</system.serviceModel>
