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>

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>
<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>
