WCF REST：WebHost 无法处理请求

Question

我有一个WCF服务部署在负载均衡器后面，当我尝试使用SOAP访问它时，它可以正常工作，但是当我尝试通过REST URL访问它时，我会收到下面提到的错误。

这是我尝试用REST URL访问它的链接：https:// devreporting.dev.sample.com/ReportingManagement.svc/getAddtionsByCategory。

负载均衡器VIP为https:// devreporting.dev.sample.com，防火墙后面只有一个服务器dev01。

我认为这可能是主机头的问题，但不确定如何解决。任何想法都将不胜感激。

请问您能否解释一下SOAP URI和Rest URI之间的区别？您是不是指一个在Http上，另一个在Https上？ - hussian

呼...我在我的<section>中缺少安全配置，当我添加了它后，一切都像魔法般地正常工作了

   <webHttpBinding>
    <binding name="CommerceRESTBinding">
        <security mode="Transport">
                <transport clientCredentialType = "None" proxyCredentialType="None"/>
        </security>

</binding>
  </webHttpBinding>

这个应该放在哪里？你能把web.config中完整的代码片段发一下吗？ - Robert Ivanc

"没有活动监听的通道"听起来就像它所说的那样。在请求发出时，端口17005上没有任何东西在监听。

确保这是正确的URL。通过从服务器机器上的命令提示符窗口发出以下命令来测试它：

telnet localhost 17005 Enter
GET /Enter ;注意：这不会回显
Enter

如果这个命令有效（连接并从IIS带回一些内容），那么从负载均衡器另一侧的客户端机器上运行相同的测试。当然，在这种情况下，使用完整的主机名而不是localhost。
