Question

我在使用wsHttpBinding和Https基地址设置WCF服务时遇到问题。

真正的问题是在客户端测试WCF中定义mex：

错误：无法从中获取元数据 https://localhost:8722/Design_Time_Addresses/_20180420_WcfServiceLibraryTest/Service1/mex 如果这是您有权访问的Windows（R）Communication Foundation服务，请检查您是否已在指定地址启用元数据发布。
有关启用元数据发布的帮助，请参阅http://go.microsoft.com/fwlink/?LinkId=65455上的MSDN文档。

App.config：

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
            <behavior name="NewBehavior0"> <!-- Error: Cannot optain metadata -->
                <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>

            <behavior name="NewBehavior1"> <!-- Error: Cannot Find Cert -->

        </wsHttpBinding>
    </bindings>

阅读SO并尝试我发现的每件事我尝试了很多配置。但没有一个显示出值得一提的进步。看起来更像，我不知道。使用wsHttpBinding使最基本的W工作（在SoapUi中编译+可测试）的正确配置是什么？

我认为可能是因为mex bindingConfiguration=""设置为空字符串？尝试删除它，或将其设置为绑定。

如果默认mexHttpBinding不起作用，请尝试将其更改为wsHttpBinding。以下是可能有用的示例Custom Secure Metadata Endpoint。它说：

在许多其他示例中，元数据端点使用默认的mexHttpBinding，这是不安全的。这里使用带有Message安全性的WSHttpBinding来保护元数据。为了使元数据客户端能够检索此元数据，必须使用匹配的绑定对它们进行配置。

需要为不同的绑定配置WCF测试客户端，但我认为它会自动配置。

<services>   
    <service name="Microsoft.ServiceModel.Samples.CalculatorService"  
             behaviorConfiguration="CalculatorServiceBehavior">  
     <!-- use base address provided by host -->  
     <endpoint address=""  
       binding="wsHttpBinding"  
       bindingConfiguration="Binding2"  
       contract="Microsoft.ServiceModel.Samples.ICalculator" />  
     <endpoint address="mex"  
       binding="wsHttpBinding"  
       bindingConfiguration="Binding1"  
       contract="IMetadataExchange" />  
     </service>  
 </services>  
 <bindings>  
   <wsHttpBinding>  
     <binding name="Binding1">  
       <security mode="Message">  
         <message clientCredentialType="Certificate" />  
       </security>  
     </binding>  
     <binding name="Binding2">  
       <reliableSession inactivityTimeout="00:01:00" enabled="true" />  
       <security mode="Message">  
         <message clientCredentialType="Certificate" />  
       </security>  
     </binding>  
   </wsHttpBinding>  
 </bindings>

mex端点错误。这就是问题的原因。以下链接包含相同的完整详细信息。
