C#WCF端点绑定和文件上载

本文关键字：文件上载绑定端点 C#WCF | 更新日期: 2023-09-27 17:59:26

我在配置basicHttpBinding的maxRecievedMessageSite属性时遇到一些问题。我想创建一个端点来上传可能较大的文件，但当前（我假设默认）限制是64K。对于图像和大型文档等项目，此限制是不起作用的。我已经从basicHttpBinding创建了一个新的绑定，但我在堆栈跟踪中不断收到错误，让我知道我已经超过了限制。下面我包括了我的配置文件、Global.asax文件、我的运营合同和我的服务实现中的相关部分。（一切都很简单，只是想让它发挥作用）。

配置文件

<system.webServer>
  <system.serviceModel>
    <services>
      <!-- CarImage Service Configuration -->
      <service name="CarImageService">
        <endpoint address="" 
                  binding="basicHttpBinding" 
                  bindingConfiguration="FileTransferServicesBinding"
                  contract="ICarImageService" />
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <!-- buffer: 64KB; max size: 64MB -->
        <binding name="FileTransferServicesBinding"
                 closeTimeout="00:01:00"
                 openTimeout="00:01:00"
                 receiveTimeout="00:01:00"
                 sendTimeout="00:01:00"
                 transferMode="Streamed"
                 messageEncoding="Mtom"
                 maxBufferSize="999999"
                 maxReceivedMessageSize="67108864"
                 maxBufferPoolSize="99999">
           <security mode="None" >
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
</system.serviceModel>

Global.asax文件

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)));
        }
    }
}

运营合同

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

我的（非常）简单实现类

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

C#WCF端点绑定和文件上载

两个问题：

您正在为地址为"的服务端点使用WCF配置，但随后使用代码使用地址为"/test"的ASP.NET路由来启动服务。您只需要将配置地址与要获取的端点配置的路由地址对齐即可
您使用basicHttpBinding配置服务，但在运行时指定WebServiceHostFactory，它将使用webHttpBinding（即REST支持）。您想将配置更改为webHttpBinding。如果它为您的服务找到了端点，那么您接下来就会出现此错误，因为绑定类型可能不匹配。

更新

今天早上我意识到#1是个坏建议。实际上，您无法将WCF服务/端点配置与ServiceRoute注册混合/匹配。因此，您有两个选项可以将特定的绑定配置应用于ServiceRoutes:

为webHttpBinding配置默认值。这绝对是最简单的方法，因为它完全是配置的，不需要对您已经在做的事情进行代码更改。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。当您要编写一堆服务项目时，这是一种更好的方法，因为所有项目都必须确保应用正确的配置条目，而不是所有项目，它们可以通过引用共享工厂实现，只需执行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>
