wsdl 未显示 XML-WCF

Question

当调用服务 url https://example.com/TestService.svc 时，我得到以下 2 个 URL，但是当我尝试点击 WSDL 时，它不起作用。

WSDL 网址

http://example.com/TestService.svc?wsdl -- 不工作

http://example.com/TestService.svc?singleWsdl -- 不工作

手动将http改为https

https://example.com/TestService.svc?wsdl -- 工作中

https://example.com/TestService.svc?singleWsdl -- 工作中

客户端配置

  <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
</client>
<behaviors>
  <serviceBehaviors>
    <clear/>
    <behavior>          
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>          
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>    
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="0" />

主要服务配置

<system.serviceModel>    
<behaviors>
  <serviceBehaviors>
    <clear />
    <behavior>
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<protocolMapping>
  <add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="0">
  <serviceActivations>
    <clear />        
    <add factory="DataServicesHost.UnityServiceHostFactory" relativeAddress="TestService.svc" service="TestService.Service" />
  </serviceActivations>
</serviceHostingEnvironment>     

服务消费

var customHeader = new MessageHeader<Security>(security);
            var tempHeader = customHeader.GetUntypedHeader("Security", "http://tempuri.org/");

            var client = new ServiceClient();

            using (var scope = new OperationContextScope(client.InnerChannel))
            {
                OperationContext.Current.OutgoingMessageHeaders.Add(tempHeader);
                objDataRequest = client.DataRequest("test");

            }

从上面的配置，我们可以推断它属于客户端。但是，WCF 服务的 WSDL 功能是在服务器端设置的。它由 ServiceMetadata 部分控制。

<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>  

因此，如果我们想让 WSDL 特性的 HTTP 协议正常工作，我们需要在服务器端启用它并在服务部分应用服务行为（端点应该在 service 部分内，而不是client 部分）。

<system.serviceModel>
    <services>
      <service name="WcfService3.Service1" behaviorConfiguration="sb">
        <endpoint address="" binding="basicHttpBinding" contract="WcfService3.IService1"></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="sb">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
</behaviors>
