Question

我在负载均衡器后部署了一个WCF服务，当我尝试使用SOAP访问它时效果很好，但是当我尝试通过REST url访问它时，我得到了下面提到的错误。

这是我尝试使用https：// devreporting.dev.sample.com/ReportingManagement.svc/getAddtionsByCategory ..

尝试访问的REST URL

负载均衡器VIP为https：// devreporting.dev.sample.com，防火墙后面只有一台服务器，即dev01

我认为这是主机标题的一些问题，但不知道如何解决这个问题。任何想法都将不胜感激。

Answer 1

Phew ...我在我的部分中缺少安全配置，当我添加它时，事情就像魅力一样

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

</binding>
  </webHttpBinding>

Answer 2

“没有主动收听的频道”听起来像它说的那样。在提出请求时，没有任何东西在侦听端口17005。

确保这是正确的网址。通过从服务器计算机上的命令提示符窗口发出以下命令来测试它：

telnet localhost 17005 输入
GET / 输入;注意：这不会回应
输入

如果这样做（从IIS连接并带回东西），则从负载均衡器远端的客户端计算机运行相同的测试。当然，在这种情况下，请使用完整的主机名而不是localhost。
