Question

我在Azure上部署了RESTful WCF服务。其中一个合同操作应该是从客户端上传的图像文件（不大于500kb）。目前，我的解决方案在Azure计算机/存储模拟器中运行时没有任何问题。但是，当我将解决方案部署到Azure时，从客户端上载（图像大小为133kb）失败，413请求实体太大。似乎Azure忽略了我在web.config中设置的配置（在Azure模拟器中正确选取）。

如何解决此问题的任何帮助将受到高度赞赏。以下是我的代码的相关摘要。

接口

namespace HappyBabiesSvc
{
    [ServiceContract]    
    public interface IHappyBabies

[OperationContract]
    [WebInvoke(UriTemplate = "/v1.0/locations/{locationID}/images",
        Method = "PUT")]
    void UploadNewImage(string locationID, Stream imageToUpload);

服务实施

<%@ ServiceHost Language="C#" Debug="true" Service="HappyBabiesSvc.HappyBabiesSvc" Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>

的Web.config

<system.serviceModel>    
    <standardEndpoints>      
      <webHttpEndpoint>        
        <standardEndpoint maxReceivedMessageSize="655360"/>
      </webHttpEndpoint>
    </standardEndpoints>    
    <serviceHostingEnvironment multipleSiteBindingsEnabled="false"/>
    <services>
      <service name="HappyBabiesSvc.HappyBabiesSvc" behaviorConfiguration="ServiceConfiguration">
        <endpoint address="" binding="webHttpBinding"
          name="HappyBabiesService"
          contract="HappyBabiesSvc.IHappyBabies" />
      </service>
    </services>
    <bindings>
    <webHttpBinding>
      <binding maxBufferSize="655360"
        maxReceivedMessageSize="655360" transferMode="Streamed">
        <readerQuotas maxDepth="655360" maxStringContentLength="655360"
          maxArrayLength="655360" maxBytesPerRead="655360" maxNameTableCharCount="655360" />
      </binding>
    </webHttpBinding>
  </bindings>
  </system.serviceModel>

尝试使用单个参数即Stream的方法。流参数应该是单独的。

[OperationContract的] [WebInvoke（UriTemplate =“/ v1.0/locations/{locationID}/images",Method =”PUT“）] void UploadNewImage（Stream imageToUpload）;

Azure上的WCF REST失败，“413请求实体太大”
