Service-Fabric绑定到多个端点

Question

是否可以绑定服务结构应用程序以侦听多个端口？

基本上我正在尝试一个面向公众的服务,它可以监听http:80和https:443,并将任何http请求重定向到https.

我创建了一个新的ASP.net核心服务,它可以单独运行.即使用SSL 443或只是非SSL 80,但是当我添加它们时ServiceInstanceListeners它只是失败!

Service Fabric Explorer在超时几次后出现以下错误:

Unhealthy event: SourceId='System.RA', Property='ReplicaOpenStatus', HealthState='Warning', ConsiderWarningAsError=false.
Replica had multiple failures in API call: IStatelessServiceInstance.Open(); Error = System.Fabric.FabricElementAlreadyExistsException (-2146233088)
Unique Name must be specified for each listener when multiple communication listeners are used

这很奇怪,因为两个听众都有不同的名字 - 所以看起来如此.在那里,我应该设置我错过的听众名称吗？

我正在使用Asp.net Core模板.我的无状态服务代码如下:

internal sealed class Web : StatelessService
{
    public Web(StatelessServiceContext context)
        : base(context)
    { }

    /// <summary>
    /// Optional override to create listeners (like tcp, http) for this service instance.
    /// </summary>
    /// <returns>The collection of listeners.</returns>
    protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
    {
        return new ServiceInstanceListener[]
        {
            new ServiceInstanceListener(serviceContext =>
                new WebListenerCommunicationListener(serviceContext, "ServiceEndpointHttps", url =>
                {
                    ServiceEventSource.Current.ServiceMessage(serviceContext, $"Starting WebListener on {url}");

                    return new WebHostBuilder()
                                .UseWebListener()
                                .ConfigureServices(
                                    services => services
                                        .AddSingleton<StatelessServiceContext>(serviceContext))
                                .UseContentRoot(Directory.GetCurrentDirectory())
                                .UseStartup<Startup>()
                                .UseUrls(url)
                                .Build();
                })),


            new ServiceInstanceListener(serviceContext =>
                new WebListenerCommunicationListener(serviceContext, "ServiceEndpointHttp", url =>
                {
                    ServiceEventSource.Current.ServiceMessage(serviceContext, $"Starting WebListener on {url}");

                    return new WebHostBuilder()
                                .UseWebListener()
                                .ConfigureServices(
                                    services => services
                                        .AddSingleton<StatelessServiceContext>(serviceContext))
                                .UseContentRoot(Directory.GetCurrentDirectory())
                                .UseStartup<Startup>()
                                .UseUrls(url)
                                .Build();
                }))
        };
    }
}

我需要设置ServiceInstanceListener具有构造函数的名称

public ServiceInstanceListener(Func<StatelessServiceContext, ICommunicationListener> createCommunicationListener, string name = "");

我没有意识到它有额外的参数:)
