c# - WCF 托管问题

Question

您好，我想知道是否有人可以帮助我，我一直在用头撞墙试图解决这个问题，但还没有运气:(我在我们内部网络的远程服务器 http://systemservices/ServiceManagerServices.svc 上的 IIS6 上托管了一个 WCF。我可以在我的浏览器中访问该服务，但是当尝试使用 WcfTestClient 发送请求时，我收到以下错误:

> Error: Cannot obtain Metadata from

我已经尝试将我的 web.config 更改为许多不同的值，这是不正确的，但是什么也没有!任何想法都将非常受欢迎!!!

这是我的 web.config

<?xml version="1.0"?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="ServiceManager.Services.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <system.web>
        <customErrors mode="Off"/>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
    <system.serviceModel>
        <services>
            <service name="ServiceManager.Services.ServiceManagerServices" behaviorConfiguration="WCFServiceBehavior">
                <endpoint address="" binding="wsHttpBinding" contract="ServiceManager.Services.IServiceManagerServices" />
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="WCFServiceBehavior">
                    <serviceMetadata httpGetEnabled="True"/>
                    <serviceDebug includeExceptionDetailInFaults="True" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true"/>
    </system.webServer>

由于您无法连接，这可能是访问限制，但当您因其他问题被踢回时，此消息会显示，因此这可能是缺少引用的二进制文件，或使用了无效的 DataContract 或类似的东西。

首先，打开一些诊断:

<system.diagnostics>
  <sources>
    <source name="System.ServiceModel" switchValue="Warning, ActivityTracing" propagateActivity="true">
      <listeners>
        <add type="System.Diagnostics.DefaultTraceListener" name="Default">
          <filter type="" />
        </add>
        <add name="ServiceModelTraceListener">
          <filter type="" />
        </add>
      </listeners>
    </source>
  </sources>
  <sharedListeners>
    <add initializeData="path\to\trace.svclog"
      type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
    name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
    <filter type="" />
  </add>
</sharedListeners>

现在运行服务，得到错误并使用SvcTraceTool (只需转至 Program Files\Microsoft SDKs 并搜索 svc)打开输出日志。这将使您对流程有更多的了解，在该点出现错误并指出异常的更多详细信息 - 有时只是告诉您查看事件日志以查找特定异常。
