WCF SOAP服务无法处理该消息，因为它发送多部分消息并且需要'text / xml; charset = utf-8'

Question

I have a problem with WCF Soap 1.1 configuration. I have created a WCF service with basicHttpBinding. Bellow the configuration. The service is WCF_SOAP_REST_SERVICE.BiasImpl:

  <system.serviceModel>
    <services>
      <service behaviorConfiguration="ServBehave" name="WCF_SOAP_REST_SERVICE.Service">
        <endpoint address="soapService" binding="basicHttpBinding" contract="WCF_SOAP_REST_SERVICE.Service" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
      <service behaviorConfiguration="ServBehave" name="WCF_SOAP_REST_SERVICE.BiasImpl">
        <endpoint address="soapService" binding="basicHttpBinding" bindingConfiguration="basicHttp"
          contract="WCF_SOAP_REST_SERVICE.BiasImpl" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
     <bindings>
        <basicHttpBinding>
          <binding name="basicHttp" bypassProxyOnLocal="true" maxBufferSize="2147483647"
    maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
             useDefaultWebProxy="false" messageEncoding="Mtom" >
            <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
      maxArrayLength="2147483647" maxBytesPerRead="2147483647"
      maxNameTableCharCount="2147483647" />
          </binding>
        </basicHttpBinding>
     </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServBehave">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

I am testing the service using SoapUI. The problem is, that I can test the service if I send small packages. I can test it and debug it with Visual Studio, but when I try to send bigger packages (for example a normal request might contain about 500kb because it will contain several images inside), the request is sent using multipart packages, and the WCF binging is configured to accept 'text/xml; charset=utf-8'. So I get this error in SoapUI

Fri Apr 24 08:16:31 EDT 2015:DEBUG:Receiving response: HTTP/1.1 415 Cannot process the message because the content type 'multipart/related; type="text/xml"; start="<rootpart@soapui.org>"; boundary="----=_Part_0_1561749008.1429877791373"' was not the expected type 'text/xml; charset=utf-8'.

This is the service interface as generated by svcutil.exe. ( The wsdl is predefined, cannot be changed)

[System.CodeDom.Compiler.GeneratedCode("System.ServiceModel", "4.0.0.0")]
[ServiceContract(Namespace="http://my.custom.url/codification/", ConfigurationName="Codification")]
public interface Codification{


.
.
.

    [OperationContract(Action="CheckQuality"/*, ReplyAction="*"*/)]
    [FaultContract(typeof(my.custom.url.CodificationFaultDetail), Action="CheckQuality", Name="CodificationFault")]
    [XmlSerializerFormat()]
    [ServiceKnownType(typeof(ResponseTemplate))]
    [ServiceKnownType(typeof(RequestTemplate))]
    CheckQualityResponse CheckQuality(CheckQuality request);

.
.
.

}

This is the implementation:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class CodificationImpl : Codification
{
    .
    .
    .

    public CheckQualityResponse CheckQuality(CheckQuality request)
    {
        //implementation goes here
    }

    .
    .
    .
}

CheckQuality class:

[System.Diagnostics.DebuggerStepThrough()]
[System.CodeDom.Compiler.GeneratedCode("System.ServiceModel", "4.0.0.0")]
[MessageContract(WrapperName="CheckQuality", WrapperNamespace="http://my.custom.url/codification/", IsWrapped=true)]
public partial class CheckQuality
{

    [MessageBodyMember(Namespace="http://my.custom.url/codification/", Order=0)]
    [System.Xml.Serialization.XmlElement(IsNullable=true)]
    public CheckQualityCheckQualityRequest CheckQualityRequest;

    public CheckQuality()
    {
    }

    public CheckQuality(CheckQualityCheckQualityRequest CheckQualityRequest)
    {
        this.CheckQualityRequest = CheckQualityRequest;
    }
}

What do I have to configure in the WCF service binding to accept multipart messages?

Answer 1

Please find the below WCF service that works from SOAPUI

Service

[ServiceContract]
    public interface IImageService
    {
        [OperationContract]
        bool CheckQualityOfImage(CheckQuality objCheckQuality);
    }


    [DataContract]
    public class CheckQuality
    {
        [DataMember]
        public MemoryStream ImageData { get; set; }
        [DataMember]
        public string ImageFileName{ get; set; }
    }

Implementation for the interface below:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class ImageService : IImageService
    {
        public bool CheckQualityOfImage(CheckQuality objCheckQuality)
        {
            if (objCheckQuality != null)
            {
                if (objCheckQuality.ImageData.Length > 0 && ! String.IsNullOrEmpty(objCheckQuality.ImageFileName))
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }
            return false;
        }
    }

Web.config on the server

<system.serviceModel>
    <bindings>
    <basicHttpBinding>
        <binding name="noSecurity" maxReceivedMessageSize="2147483647">
              <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647"
                            maxDepth="64" maxNameTableCharCount="2147483647" />
              <security mode="None"></security>
            </binding>
    </basicHttpBinding>
    </bindings>
    <services>
          <service name="XMLService.ImageService" behaviorConfiguration="default">
            <endpoint address="" binding="basicHttpBinding" bindingConfiguration="noSecurity" contract="XMLService.IImageService" />
          </service>
    </services>
    <behaviors>
        <behavior name="default">
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />      
        </behavior>
    </behaviors>
</system.serviceModel>

Now my request from SOAPUI is as shown in the screenshots attached

Make sure to match the request properties in SOAPUI. Some more information on using SOAPUI with attachments can be found here

NOTE: I have made a few assumptions on properties in the CheckQuality class and I have used a 6MB file for upload
