WCF学习笔记二

　　客户端调用WCF服务出现以下错误：

“/”应用程序中的服务器错误。

---

远程服务器返回错误: (415) Unsupported Media Type。

说明: 执行当前 Web 请求期间，出现未经处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 

异常详细信息: System.Net.WebException: 远程服务器返回错误: (415) Unsupported Media Type。

堆栈跟踪: 

[WebException: 远程服务器返回错误: (415) Unsupported Media Type。] System.Net.HttpWebRequest.GetResponse() +6449128 System.ServiceModel.Channels.HttpChannelRequest.WaitForReply(TimeSpan timeout) +55 [ProtocolException: 服务 http://localhost:1234/AreaService.svc 不支持内容类型 text/xml; charset=utf-8。客户端和服务绑定可能不匹配。]

 

　　观察堆栈可以知道，这是因为客户端和服务端绑定不匹配造成的，代码如下：

服务端配置节点信息：
<system.serviceModel>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

<services>

<!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->

<service name="SOA.Services.SearchConfigBiz" behaviorConfiguration="a1">

<endpoint contract="SOA.Contract.ISearchConfig" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.ISearchConfig" binding="mexHttpBinding" address="mex"/>

</service>

<service name="SOA.Services.SubjectBiz" behaviorConfiguration="a1">

<endpoint contract="SOA.Contract.ISubject" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.ISubject" binding="mexHttpBinding" address="mex"/>

</service>

<service name="SOA.Services.AreaBiz" behaviorConfiguration="a1">

<endpoint contract="SOA.Contract.IArea" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.IArea" binding="mexHttpBinding" address="mex"/>

</service>

<service name="SOA.Services.YearBiz" behaviorConfiguration="a1">

<endpoint contract="SOA.Contract.IYear" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.IYear" binding="mexHttpBinding" address="mex"/>

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name="a1">

<serviceDebug includeExceptionDetailInFaults="true" />

<serviceMetadata httpGetEnabled="true" />

</behavior>

<behavior name="">

<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

<serviceDebug includeExceptionDetailInFaults="false" />

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>

 

客户端配置节点信息：

<system.serviceModel>

<bindings>

<basicHttpBinding>

<binding name="BasicHttpBinding_SubjectContract" />

<binding name="BasicHttpBinding_AreaContract" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" />

<binding name="BasicHttpBinding_SearchConfigContract" />

<binding name="BasicHttpBinding_YearContract" />

</basicHttpBinding>

<wsHttpBinding>

<binding name="MetadataExchangeHttpBinding_SubjectContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_AreaContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_SearchConfigContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_YearContract">

<security mode="None" />

</binding>

</wsHttpBinding>

</bindings>

<client>

<endpoint address="http://localhost:1234/AreaService.svc" binding="basicHttpBinding"

bindingConfiguration="BasicHttpBinding_AreaContract" contract="AreaService.AreaContract"

name="BasicHttpBinding_AreaContract" />

<endpoint address="http://localhost:1234/SearchConfigService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_SearchConfigContract"

contract="SearchConfigService.SearchConfigContract" name="BasicHttpBinding_SearchConfigContract" />

<endpoint address="http://localhost:1234/SubjectService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_SubjectContract"

contract="SubjectService.SubjectContract" name="BasicHttpBinding_SubjectContract" />

<endpoint address="http://localhost:1234/YearService.svc" binding="basicHttpBinding"

bindingConfiguration="BasicHttpBinding_YearContract" contract="YearService.YearContract"

name="BasicHttpBinding_YearContract" />

</client>

</system.serviceModel>

 

所以，只需要将客户端和服务端的配置保持一致即可。

代码如下:

1.使用basicHttpBinding：

客户端配置节点信息：



<system.serviceModel>

<bindings>

<basicHttpBinding>

<binding name="BasicHttpBinding_SubjectContract" />

<binding name="BasicHttpBinding_AreaContract" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" />

<binding name="BasicHttpBinding_SearchConfigContract" />

<binding name="BasicHttpBinding_YearContract" />

</basicHttpBinding>

<wsHttpBinding>

<binding name="MetadataExchangeHttpBinding_SubjectContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_AreaContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_SearchConfigContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_YearContract">

<security mode="None" />

</binding>

</wsHttpBinding>

</bindings>

<client>

<endpoint address="http://localhost:1234/AreaService.svc" binding="basicHttpBinding"

bindingConfiguration="BasicHttpBinding_AreaContract" contract="AreaService.AreaContract"

name="BasicHttpBinding_AreaContract" />

<endpoint address="http://localhost:1234/SearchConfigService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_SearchConfigContract"

contract="SearchConfigService.SearchConfigContract" name="BasicHttpBinding_SearchConfigContract" />

<endpoint address="http://localhost:1234/SubjectService.svc"

binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_SubjectContract"

contract="SubjectService.SubjectContract" name="BasicHttpBinding_SubjectContract" />

<endpoint address="http://localhost:1234/YearService.svc" binding="basicHttpBinding"

bindingConfiguration="BasicHttpBinding_YearContract" contract="YearService.YearContract"

name="BasicHttpBinding_YearContract" />

</client>

</system.serviceModel>



服务端配置节点信息：



<system.serviceModel>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"  multipleSiteBindingsEnabled="true" />

    <services>

      <!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->

      <service name="SOA.Services.SearchConfigBiz" behaviorConfiguration="a1">

        <endpoint contract="SOA.Contract.ISearchConfig" binding="basicHttpBinding"/>

        <endpoint contract="SOA.Contract.ISearchConfig" binding="mexHttpBinding" address="mex"/>

      </service>

      <service name="SOA.Services.SubjectBiz" behaviorConfiguration="a1">

        <endpoint contract="SOA.Contract.ISubject" binding="basicHttpBinding"/>

        <endpoint contract="SOA.Contract.ISubject" binding="mexHttpBinding" address="mex"/>

      </service>

      <service name="SOA.Services.AreaBiz" behaviorConfiguration="a1">

        <endpoint contract="SOA.Contract.IArea" binding="basicHttpBinding"/>

        <endpoint contract="SOA.Contract.IArea" binding="mexHttpBinding" address="mex"/>

      </service>

      <service name="SOA.Services.YearBiz" behaviorConfiguration="a1">

        <endpoint contract="SOA.Contract.IYear" binding="basicHttpBinding"/>

        <endpoint contract="SOA.Contract.IYear" binding="mexHttpBinding" address="mex"/>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="a1">

          <serviceDebug includeExceptionDetailInFaults="true" />

          <serviceMetadata httpGetEnabled="true" />

        </behavior>

        <behavior name="">

          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

          <serviceDebug includeExceptionDetailInFaults="false" />

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>

使用basicHttpBinding

 

2.使用wsHttpBinding:

客户端配置节点信息：



<system.serviceModel>

<bindings>

<wsHttpBinding>

<binding name="BasicHttpBinding_SubjectContract" />

<binding name="BasicHttpBinding_AreaContract" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" />

<binding name="BasicHttpBinding_SearchConfigContract" />

<binding name="BasicHttpBinding_YearContract" />

</wsHttpBinding>

<basicHttpBinding>

<binding name="MetadataExchangeHttpBinding_SubjectContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_AreaContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_SearchConfigContract">

<security mode="None" />

</binding>

<binding name="MetadataExchangeHttpBinding_YearContract">

<security mode="None" />

</binding>

</basicHttpBinding>

</bindings>

<client>

<endpoint address="http://localhost:1234/AreaService.svc" binding="wsHttpBinding"

bindingConfiguration="BasicHttpBinding_AreaContract" contract="AreaService.AreaContract"

name="BasicHttpBinding_AreaContract" />

<endpoint address="http://localhost:1234/SearchConfigService.svc"

binding="wsHttpBinding" bindingConfiguration="BasicHttpBinding_SearchConfigContract"

contract="SearchConfigService.SearchConfigContract" name="BasicHttpBinding_SearchConfigContract" />

<endpoint address="http://localhost:1234/SubjectService.svc"

binding="wsHttpBinding" bindingConfiguration="BasicHttpBinding_SubjectContract"

contract="SubjectService.SubjectContract" name="BasicHttpBinding_SubjectContract" />

<endpoint address="http://localhost:1234/YearService.svc" binding="wsHttpBinding"

bindingConfiguration="BasicHttpBinding_YearContract" contract="YearService.YearContract"

name="BasicHttpBinding_YearContract" />

</client>

</system.serviceModel>





服务端配置节点信息：



<system.serviceModel>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

<services>

<!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->

<service name="SOA.Services.SearchConfigBiz" behaviorConfiguration="a1">

<endpoint contract="SOA.Contract.ISearchConfig" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.ISearchConfig" binding="mexHttpBinding" address="mex"/>

</service>

<endpoint contract="SOA.Contract.IYear" binding="wsHttpBinding"/>

<endpoint contract="SOA.Contract.IYear" binding="mexHttpBinding" address="mex"/>

</service>

</services>

<behaviors>

<serviceBehaviors>

<behavior name="a1">

<serviceDebug includeExceptionDetailInFaults="true" />

<serviceMetadata httpGetEnabled="true" />

</behavior>

<behavior name="">

<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

<serviceDebug includeExceptionDetailInFaults="false" />

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>
