在 https://... 上没有可以接受消息的端点监听。这通常是由不正确的地址或 SOAP 操作引起的

Question

我正在使用第 3 方网络服务，我可以从浏览器查看和运行它没有问题

我已将服务引用添加到 Visual Studio 并指定了名称页：

因为它是一个网络应用程序，所以我将相关位从 app.config 复制到 web.config

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="MembersSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding>
        <binding name="BookingsSoap">
          <security mode="Transport"> 
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
            <message clientCredentialType="Certificate" algorithmSuite="Default" />
         </security>
         </binding> 

      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://server/directory/Members.asmx" binding="basicHttpBinding" bindingConfiguration="MembersSoap" contract="MWSMembers.MembersSoap" name="MembersSoap" />
      <endpoint address="https://server/directory/Bookings.asmx" binding="basicHttpBinding" bindingConfiguration="BookingsSoap" contract="MWSBookings.BookingsSoap" name="BookingsSoap" />

   </client>
  </system.serviceModel>

这是我使用 MWSBookings 网络服务的方法：

private string GetBookings()
{
    using (MWSBookings.BookingsSoapClient client = new MWSBookings.BookingsSoapClient())
    {
        try
        {

            var bookings = client.ListBookableActivitiesClassesCourses(GetMemberAuthHeader2(), 0123456, "5", false);
            return bookings.ToString();

        }
        catch (Exception ex)
        {
            return ex.Message.ToString();
        }
    }


}

当我构建我的解决方案并查看浏览器页面时，我收到以下错误：

在https://server/directory/Bookings.asmx 上没有可以接受消息的端点监听。这通常是由不正确的地址或 SOAP 操作引起的。有关详细信息，请参阅 InnerException（如果存在）。

我已经搜索了 Stack Overflow 上的所有其他帖子，但没有一个解决方案对我的情况有所帮助。我已确保安装了 HTTP 激活功能，我尝试将 AppPool 从 appPoolIdentity 运行到 NetworkService，但没有帮助。还尝试在 web.config 中包含 maxRequestLength 和 maxAllowedContentLength 并增加限制但没有区别。

如果有人能提供任何建议，我将不胜感激。

谢谢 斯科特

更新 以下是完整的异常消息：

        System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at https://server/directory/Bookings.asmx 
that could accept the message. This is often caused by an incorrect address or SOAP action.

问题出在代理服务器上，我在调用我的网络服务之前添加了以下几行，并且错误消息现在已经消失了。

var proxy = new WebProxy("myproxy:8080", true);

proxy.Credentials = new NetworkCredential("username", "password");

WebRequest.DefaultWebProxy = proxy;
