WCF服务接受一个后编码的多部分/表单数据 [英] WCF service to accept a post encoded multipart/form-data

问题描述

有谁知道，或者更好的例子是一个WCF服务，它将接受编码为 multipart / form-data 的表单过帐。从网页文件上传？

我在google上空了。

Ta，Ant

解决方案

所以，这里就是...

创建您的服务合约这是一个接受流的唯一参数的操作，如下所示用WebInvoke装饰

  [ServiceContract] 
 public interface IService1 {
 $ b $ [OperationContract] 
 [WebInvoke（
 Method =POST，
 BodyStyle = WebMessageBodyStyle.Bare，
 UriTemplate =/ Upload ）] 
无效上传（流数据）; 
 
 
 
 
 
 
 
创建类... 
  public class Service1：IService1 {
 
 public void Upload（流数据）{
 
 //从WebOperationContext.Current.IncomingRequest.Headers获取标题信息
 //打开并解码多部分数据，保存到所需位置
} 
  
以及配置，接受流数据以及最大大小
  < system.serviceModel> 
< bindings> 
< webHttpBinding> 
< binding name =WebConfiguration
 maxBufferSize =65536
 maxReceivedMessageSize =2000000000
 transferMode =Streamed> 
< / binding> 
< / webHttpBinding> 
< / bindings> 
<行为> 
< endpointBehaviors> 
< behavior name =WebBehavior> 
< webHttp /> 
< /行为> 
< / endpointBehaviors> 
< serviceBehaviors> 
< behavior name =Sandbox.WCFUpload.Web.Service1Behavior> 
< serviceMetadata httpGetEnabled =truehttpGetUrl =/> 
< serviceDebug includeExceptionDetailInFaults =false/> 
< /行为> 
< / serviceBehaviors> 
< /行为> 
< services> 
< service name =Sandbox.WCFUpload.Web.Service1behaviorConfiguration =Sandbox.WCFUpload.Web.Service1Behavior> 
  address =
 binding =webHttpBinding
 behaviorConfiguration =WebBehavior
 bindingConfiguration =WebConfiguration
 contract =沙盒.WCFUpload.Web.IService1/> 
< / service> 
< / services> 
< /system.serviceModel> 
  
另外在System.Web中增加了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，但允许添加一个Progress方法来显示ajax进度条你可能想添加一些安全性。
 
Does anyone know, or better yet have an example, of a WCF service that will accept a form post encoded multipart/form-data ie. a file upload from a web page?

I have come up empty on google.

解决方案
So, here goes...

Create your service contract which an operation which accepts a stream for its only parameter, decorate with WebInvoke as below
[ServiceContract]
public interface IService1 {

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

}
Create the class...
    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
    }
And the config, to accept streamed data, and the maximum size
<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>
Also in the System.Web increase the amount of data allowed in System.Web
<system.web>
        <otherStuff>...</otherStuff>
        <httpRuntime maxRequestLength="2000000"/>
</system.web>
This is just the basics, but allows for the addition of a Progress method to show an ajax progress bar and you may want to add some security.
