WCF服务接受后期编码的多部分/表单数据

Question

有谁知道或更佳的WCF服务示例，该服务将接受表单后编码的multipart/form-data即。从网页上传文件？

我在Google上空了。

Answer 1

所以，这里…

创建您的服务合同，该操作将接受流作为其唯一参数的操作，并使用WebInvoke装饰如下

[ServiceContract]
public interface IService1 {

    [OperationContract]
    [WebInvoke(
        Method = "POST",
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "/Upload")]
    void Upload(Stream data);

}

创建课程…

    public class Service1 : IService1 {

    public void Upload(Stream data) {

        // Get header info from WebOperationContext.Current.IncomingRequest.Headers
        // open and decode the multipart data, save to the desired place
    }

和配置，接受流数据，并且最大大小

<system.serviceModel>
   <bindings>
     <webHttpBinding>
       <binding name="WebConfiguration" 
                maxBufferSize="65536" 
                maxReceivedMessageSize="2000000000"
                transferMode="Streamed">
       </binding>
     </webHttpBinding>
   </bindings>
   <behaviors>
     <endpointBehaviors>
       <behavior name="WebBehavior">
         <webHttp />         
       </behavior>
     </endpointBehaviors>
     <serviceBehaviors>
       <behavior name="Sandbox.WCFUpload.Web.Service1Behavior">
         <serviceMetadata httpGetEnabled="true" httpGetUrl="" />
         <serviceDebug includeExceptionDetailInFaults="false" />
       </behavior>
     </serviceBehaviors>
   </behaviors>
   <services>     
     <service name="Sandbox.WCFUpload.Web.Service1" behaviorConfiguration="Sandbox.WCFUpload.Web.Service1Behavior">
      <endpoint 
        address=""
        binding="webHttpBinding" 
        behaviorConfiguration="WebBehavior"
        bindingConfiguration="WebConfiguration"
        contract="Sandbox.WCFUpload.Web.IService1" />
    </service>
  </services>
 </system.serviceModel>

同样在System.Web中增加System.Web中允许的数据量

<system.web>
        <otherStuff>...</otherStuff>
        <httpRuntime maxRequestLength="2000000"/>
</system.web>

这只是基础知识，但是允许添加Progress方法以显示ajax进度栏，并且您可能需要增加一些安全性。
