WCF 路由器 - 不路由

Question

我在控制台应用程序中有一个运行良好的 WCF 路由器，但我需要在 Azure 中托管它。因此，我被要求将其制作为 Web 应用程序，以便它可以作为应用程序服务托管。

我的路由器现在使用这个作为配置

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
  multipleSiteBindingsEnabled="true" />
<services>
  <service name="System.ServiceModel.Routing.RoutingService">
    <endpoint
              binding="basicHttpBinding"
              contract="System.ServiceModel.Routing.IRequestReplyRouter"
              name="proposalRouter" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:54636/routingService"/>

      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceDebug includeExceptionDetailInFaults="true" />
      <routing filterTableName="proposalRoutingTableVersion"/>
      <serviceMetadata httpGetEnabled="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <basicHttpBinding>
    <binding
      name="TestBinding"
      allowCookies="True"
      closeTimeout="00:04:00"
      openTimeout="00:00:10"
      receiveTimeout="00:05:00"
      sendTimeout="00:05:00"
      maxReceivedMessageSize="15728640">
      <security mode="None" />
    </binding>
  </basicHttpBinding>
</bindings>
<routing>
  <namespaceTable>
    <add prefix="xxx" namespace="xxxxx"/>
  </namespaceTable>
  <filters>
    <filter name="version_0_9"
            filterType="Custom"
            filterData="0.9"
            customType="RouterService.Asp.VersionFilter, RouterService.Asp"
    />
    <filter name="version_1_0"
            filterType="Custom"
            filterData="1.0"
            customType="RouterService.Asp.VersionFilter, RouterService.Asp"
    />
  </filters>
  <filterTables>
    <filterTable name="proposalRoutingTableVersion">
      <!--<add filterName="version_0_9" endpointName="version_0_9"/>
      <add filterName="version_1_0" endpointName="version_1_0"/>
      -->
      <!-- Acts as the else clause-->
      <!--
      <add filterName="noVersion" endpointName="version_0_9"/>-->

      <add filterName="version_0_9" endpointName="version_0_9" priority="1"/>
      <add filterName="version_1_0" endpointName="version_1_0" priority="0"/>

    </filterTable>
  </filterTables>
</routing>

<client>
  <endpoint address="http://localhost:63690/ProposalService_1_00.svc"
            binding="basicHttpBinding"
            contract="*"
            name="version_1_0"/>

  <!--<endpoint address="http://localhost:63690/ProposalService.svc"
            binding="basicHttpBinding"
            contract="*"
            name="version_0_9"/>-->

  <!--<endpoint address="http://localhost:63253/ProposalService.svc"
            binding="basicHttpBinding"
            contract="*"
            name="version_0_9"/>-->
</client>

这会落入版本过滤器

public class VersionFilter : MessageFilter
{
    private string _filterData;
    private readonly XNamespace _xmlnsa = "xxxxxx";

    public VersionFilter(string filterData)
    {
        _filterData = filterData;
    }

    public override bool Match(MessageBuffer buffer)
    {
        throw new NotImplementedException();
    }

    public override bool Match(Message message)
    {
        XDocument doc = XDocument.Parse(message.ToString());

        var version = (from xml in doc.Descendants(_xmlnsa + "getProposal")
                       select xml.Attribute("version")).FirstOrDefault();

        return _filterData == version.Value.ToString(); ;
    }
}

然后给出 true 或 false 响应，然后没有命中我试图命中的任何一个 WebService 端点。

我在很多地方寻找过这个问题的答案，但我看到的所有地方都显示了与我现有的代码相同\相似的代码。

一些建议谈到用 [EnumMember] 装饰我的枚举，所以去把它添加到每个枚举中。这没有帮助。

我已经从 basic 更改为 wsHttpBinding，这也没有帮助，然后我得到了 415 错误。

我不明白为什么\如何从控制台应用程序更改为 ASP.Net WCF 应用程序和 ASP.Net Web 应用程序会导致它停止工作。

为了不遗漏任何我没有看到的内容，这是收到的回复。

我试过启用日志，但还没写到日志，所以不确定还能尝试或做什么。

Answer 1

所以，事实证明 web.config 文件中的这一行是问题所在

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
                           multipleSiteBindingsEnabled="true" />

按照此处的建议删除此行 https://seroter.com/2010/09/19/lesson-learned-wcf-routing-service-and-the-basichttpbinding/ 是问题的解决方案。
