Azure 上的 WCF REST 因“413 请求实体太大”而失败

Question

我在 Azure 上部署了一个 RESTful WCF 服务。其中一项合约操作应该是获取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，从客户端上传（图像大小为 133kb）失败并显示 413 Request Entity Too Large。似乎 Azure 忽略了我在 web.config 中设置的配置（在 Azure 模拟器中正确获取）。

任何有关如何解决此问题的帮助将不胜感激。以下是我的代码的相关sn-ps。

界面

namespace HappyBabiesSvc
{
    [ServiceContract]    
    public interface IHappyBabies

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

服务实现

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

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">

          maxArrayLength="655360" maxBytesPerRead="655360" maxNameTableCharCount="655360" />
      </binding>
    </webHttpBinding>
  </bindings>
  </system.serviceModel>

仅尝试使用单个参数的方法，即 Stream 。 流参数应该是单独的。

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