.net - 添加程序集引用时的端点？

Question

我有一个使用对类库的引用的 WCF 服务。该库中的类执行与数据库交互之类的操作。我正在通过浏览器使用 restful 调用测试我的服务（编译时没有错误），它只显示一个页面，上面只显示“找不到端点。”。我假设这与库引用连接字符串和应用程序设置等（我通常必须包含在使用该库的应用程序中）的事实有关。所以我很难找到的是如何正确配置 wcf 服务以使用这个库。我尝试简单地将连接字符串和应用程序设置添加到 wcf web.config，但这似乎没有帮助。我觉得这只是通过服务的端点部分添加对库的引用。但我迷路了。任何帮助表示赞赏。谢谢

好的，所以我让它工作了。似乎是主机地址的问题。我将项目重新创建为服务库而不是服务应用程序，我注意到默认配置中有几个新字段。其中之一是给主人的。当我设置基地址时，一切都开始工作了。这是配置：

<system.serviceModel>
<services>
  <service name="ServiceWithLibraryTest.UtiService">
    <endpoint address="" binding="webHttpBinding" contract="ServiceWithLibraryTest.IUtiService" behaviorConfiguration="web" />        
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/ServiceWithLibraryTest/UtiService/"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>

我对 WCF 有点陌生，据我了解，配置经常令人头疼是臭名昭著的。我仍在努力研究端点，但我开始更好地理解端点如何只是暴露服务和行为的方式，即它们是如何通信的。然后，当然，休息服务为其添加了一个全新的层。我很欣赏这些想法:)
