wcf - 导致 ServiceActivationException 的原因是什么？

Question

我有一个托管在 Azure 环境中的服务。我正在使用控制台应用程序使用该服务。这样做时，我得到了异常:

"The requested service, 'http://xxxx-d.yyyy.be/Services/zzzzInService.svc' could not be activated. See the server's diagnostic trace logs for more information."

谁能帮我找到我缺少的东西？

该服务的定义如下 -

<service name="xxxx.AppServer.Host.Services.yyyyy.zzzzPlugInService"
   behaviorConfiguration="MetadataBehavior" xdt:Locator="XPath(//service[@name='xxxx.AppServer.Host.Services.yyyy.zzzzPlugInService'])" xdt:Transform="Replace">

<endpoint address="" binding="basicHttpBinding"  bindingConfiguration="basicHttpBinding" contract="xxxx.Shared.IntegrationServices.yyyy.IzzzzPlugInService">
  <identity>
    <dns value="localhost"/>
  </identity>
</endpoint>
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpsBinding" contract="xxxx.Shared.IntegrationServices.yyyy.IzzzzPlugInService">
  <identity>
    <dns value="localhost"/>
  </identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

当我使用链接 http://xxxx-d.yyyy.be/Services/zzzzInService.svc在浏览器中，我收到这些消息-

The binding at system.serviceModel/bindings/basicHttpBinding does not have a configured binding named 'basicHttpBinding'. This is an invalid value for bindingConfiguration.

<endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding" contract="xxxx.Shared.IntegrationServices.zzzzz.IzzzzPlugInService">

该错误表明您没有名为“basicHttpBinding”的“basicHttpBinding”的绑定(bind)配置。由于您没有发布完整的配置，并且错误消息说，我假设是这种情况。

下面的配置(在 <system.serviceModel> 下)在 <basicHttpBinding> 下有两个绑定(bind)定义，一个用于您在端点声明中的每个绑定(bind)配置。您的配置中也应该有类似的东西。

<services>
    <service name="xxxx.AppServer.Host.Services.yyyyy.zzzzPlugInService"
             behaviorConfiguration="MetadataBehavior"
            xdt:Locator="XPath(//service[@name='xxxx.AppServer.Host.Services.yyyy.zzzzPlugInService'])"
            xdt:Transform="Replace">
        <endpoint address=""
                  binding="basicHttpBinding" 
                  bindingConfiguration="basicHttpBinding"
                  contract="xxxx.Shared.IntegrationServices.yyyy.IzzzzPlugInService">
            <identity>
                <dns value="localhost"/>
            </identity>
        </endpoint>
        <endpoint address="" 
                  binding="basicHttpBinding" 
                  bindingConfiguration="basicHttpsBinding" 
                  contract="xxxx.Shared.IntegrationServices.yyyy.IzzzzPlugInService">
            <identity>
                <dns value="localhost"/>
            </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
    </service>
</services>
<bindings>
    <basicHttpBinding>
        <binding name="basicHttpBinding" />
        <binding name="basicHttpsBinding">
            <security mode="Transport" />
        </binding>
    </basicHttpBinding>
</bindings>
