例外：从RESTFUL服务调用Bing翻译服务时找不到默认端点元素

Question

我正在构建一个RESTFUL Web服务和一个consoleHost应用程序来托管该Web服务。 在RESTFUL webservice中，我调用BingTranslate服务（链接参考： http ：//api.microsofttranslator.com/V2/Soap.svc）我的服务主机成功，但当我调用调用BingTranslate服务的函数时，抛出此异常：无法找到引用ServiceModel客户端配置部分中的合同“BingTranslator.LanguageService”的默认端点元素。这可能是因为找不到您的应用程序的配置文件，或者因为在客户端元素中找不到与此合同匹配的端点元素。 “ （BingTranslator是RESTFUL项目中服务引用的名称）

RESTFUL项目的app.config是：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_LanguageService" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
          useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
            maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None"

            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>

      <webHttpBinding>
        <binding transferMode="Streamed" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" openTimeout="00:25:00"
                 closeTimeout="00:25:00" sendTimeout="00:25:00" receiveTimeout="00:25:00" name="webBinding">
        </binding>
      </webHttpBinding>

    </bindings>
    <client>
      <endpoint address="http://api.microsofttranslator.com/V2/soap.svc"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_LanguageService"
        contract="BingTranslator.LanguageService" name="BasicHttpBinding_LanguageService" />
    </client>
    <services>
      <service name="SearchService.Service1" behaviorConfiguration="SearchService.Service1Behavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8732/Design_Time_Addresses/SearchService/Service1/"   />
          </baseAddresses>
        </host>

        <endpoint address=""  binding="webHttpBinding" contract="SearchService.IService1"
                     behaviorConfiguration="Web" bindingConfiguration="webBinding">

          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="SearchService.Service1Behavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="Web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </system.serviceModel>

和ConsoleHost的app.config文件是这样的：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="NewBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="Web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="NewBehavior" name="SearchService.Service1">
        <clear />
        <endpoint address="" binding="webHttpBinding" contract="SearchService.IService1"
            behaviorConfiguration ="Web" />
        <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
            contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8787/searchservice" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
</configuration>

“如果您在类库中调用服务并从另一个项目调用类库，则会出现此错误。” - >也许这就是我的情况。 但我不知道如何解决它。

我该怎么办？ 请帮我。 非常感谢。 最好的祝福

如果在单独的类库项目中具有服务客户端，则引用项目不会继承wcf客户端配置（即app.config中的system.servicemodel部分）。 您需要将类库项目中app.config的System.ServiceModel部分复制到exe项目中的app.config。
