Azure应用服务应POST请求返回404

Question

我有一个WCF服务，该服务已通过VS 2017发布到Azure。我可以使用浏览器中的URL来访问该服务，并且它按预期方式工作。该服务侦听来自Salesforce的出站消息。如果我发送消息，它将返回404错误。该相同服务可以很好地发布到服务器上的IIS。 App Service中是否存在允许处理POST的设置？

更新：我认为问题可能出在web.config上，这是我拥有的：

  <system.serviceModel>
    <bindings />
    <client />
    <services>
      <service name="WorkflowNotificationServices.CaseNotificationService" behaviorConfiguration="debug">
        <endpoint binding="basicHttpBinding" contract="CaseNotificationService" />
      </service>
      <service name="WorkflowNotificationServices.CommentNotificationService" behaviorConfiguration="CommentNotificationServiceBehavior">
        <endpoint binding="basicHttpBinding" contract="CommentNotificationService" />
      </service>
      <service name="WorkflowNotificationServices.TaskNotificationService" behaviorConfiguration="TaskNotificationServiceBehavior">
        <endpoint binding="basicHttpBinding" contract="TaskNotificationService" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="CaseNotificationServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
        <behavior name="CommentNotificationServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
        <behavior name="TaskNotificationServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
        <behavior name="debug">
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

这在带有IIS的VM上正常工作。
