c# – FabricConnectionDeniedException – 在哪里设置Azure Service Fabric连接?

我正在尝试创建一个Visual Studio项目模板,其中包含一个带有StatelessService的Azure Service Fabric项目.

在锅炉板Program EntryPoint代码中,我收到了FabricConnectionDeniedException.我在哪里设置连接信息或以其他方式修复此例外?我正在运行本地群集管理器.我查看了各种.xml配置文件,但没有看到任何内容.我是否需要在Cluster Manager中将我的应用程序列入白名单?

这是我从Azure Service Fabric复制的锅炉板代码:

private static void Main() { try { // Creating a FabricRuntime connects this host process to the Service Fabric runtime. using (var fabricRuntime = System.Fabric.FabricRuntime.Create()) { // The ServiceManifest.XML file defines one or more service type names. // RegisterServiceType maps a service type name to a .NET class. // When Service Fabric creates an instance of this service type,// an instance of the class is created in this host process. fabricRuntime.RegisterServiceType( “RunSetManagerServiceType”,typeof(RunSetManagerService)); ServiceEventSource.Current.ServiceTypeRegistered( Process.GetCurrentProcess().Id,typeof(RunSetManagerService).Name); // Prevents this host process from terminating to keep the service host process running. Thread.Sleep(Timeout.Infinite); } } catch (Exception e) { // !!!!!! GETTING FabricConnectionDeniedException HERE !!!!! ServiceEventSource.Current.ServiceHostInitializationFailed(e.ToString()); throw; } }解决方法 这是因为您在Service Fabric运行时环境之外运行服务EXE.当您将服务编译为EXE时,您不能单独执行它;您必须“部署”Service Fabric集群,Service Fabric运行时环境将为您执行该集群.

如果要通过Visual Studio进行部署,请确保将应用程序项目设置为启动项目,而不是服务项目(启动项目将在解决方案资源管理器中以粗体显示).

此外,与您看到的错误无关但只是抬头:当您升级到最新的2.0.135 SDK时,您需要更新服务注册码以使用新的ServiceRuntime:

try{ ServiceRuntime.RegisterServiceAsync(“RunSetManagerServiceType”,context => new RunSetManagerService(context)).GetAwaiter().GetResult(); ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id,typeof(Stateless1).Name); // Prevents this host process from terminating so services keep running. Thread.Sleep(Timeout.Infinite);}catch (Exception e){ ServiceEventSource.Current.ServiceHostInitializationFailed(e.ToString()); throw;}
