我的应用程序连接到两个 WCF 服务。一种是较旧的 http 协议。另一个是较新的和 https。到现在为止他们都玩得很好。
但是，我现在发现我的旧服务被 BitDefender 和其他端点保护阻止，因为它是 http。因此，我试图让旧服务使用 https，但保持向后兼容仍使用 http 的之前补丁级别。所以我所做的就是将旧服务器（我将其称为 Walrus）转换为同时监听 http 和 https。旧服务和新服务均采用 .NET 编码并在同一台计算机上的 IIS 10 上运行，但侦听不同的 URL。
但是，当我安装旧服务的配置以侦听 https 时，较新的服务会中断，并显示以下消息：
There was no endpoint listening at https://cloudbackups.mycompany.net/cumulus.svc/cumulus.svc/PCBA that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
内部异常消息如下：
The remote server returned an error: (404) Not Found.
如果我恢复到之前的配置，就没有问题了。我很困惑。
旧版 WCF 的 Web.config：
<?xml version="1.0"?>
<configuration>
<!-- Services Configuration over HTTP and HTTPS -->
<connectionStrings configSource="connectionstrings.config"/>
<!--

以及较新 WCF 的服务器配置：
<?xml version="1.0" encoding="utf-8"?>
<!-- PedGuard Configuration over HTTPS -->
<configuration>
<connectionStrings configSource="connectionStrings.config" />
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

<!--

<directoryBrowse enabled="false" />
</system.webServer>
</configuration>
<!--ProjectGuid: D9EFA79D-236B-4FAA-9C45-B7A61C485DF5-->
最后是客户端配置：
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BA" />
<binding name="PCBA">
<security mode="Transport" />
</binding>
</basicHttpBinding>
<wsHttpBinding>

</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://services.mycompany.net/Walrus.svc/BA"
binding="basicHttpBinding" bindingConfiguration="BA" contract="Walrus.PTRemote"
name="BA" />
<endpoint address="http://services.mycompany.net/Walrus.svc/WsPlain"
binding="wsHttpBinding" bindingConfiguration="WsPlain" contract="Walrus.PTRemote"
name="WsPlain">
<identity>
<servicePrincipalName value="host/PF2WebMaster" />
</identity>
</endpoint>
<endpoint address="https://CloudBackups.mycompany.net/cumulus.svc/cumulus.svc/PCBA"
binding="basicHttpBinding" bindingConfiguration="PCBA" contract="cumulus.iPTPEDBackup"
name="PCBA" />
</client>
</system.serviceModel>
由于是404错误，所以很容易检查问题。
请检查为什么网址中有两个
cumulus.svc并确保以下网址在您的本地有效。
https://cloudbackups.mycompany.net/cumulus.svc/PCBA
