[英]How to obtain PartitionInfo in an Azure Service Fabric ASP.NET Core stateful service?
我们如何访问有状态服务的Controller类中的ParitionInfo对象?
这是对象的链接: https : //docs.microsoft.com/zh-cn/dotnet/api/system.fabric.servicenotification.partitioninfo?view=azure-dotnet
public class MyConntroller : ControllerBase
{
[HttpPost]
public async Task<IActionResult> Save(MyObject obj)
{
//Here I would like to access ParitionInfo object. How?!
}
}
这是ASP.NET Core有状态服务中的服务定义,可以从定义该对象的基类轻松获取该对象:
/// <summary>
/// The FabricRuntime creates an instance of this class for each service
/// type instance.
/// </summary>
internal sealed class MyStatefulService : StatefulService
{
public MyStatefulService(StatefulServiceContext 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<ServiceReplicaListener> CreateServiceReplicaListeners()
{
return new ServiceReplicaListener[]
{
new ServiceReplicaListener(serviceContext =>
new KestrelCommunicationListener(serviceContext, (url, listener) =>
{
ServiceEventSource.Current.ServiceMessage(serviceContext, $"Starting Kestrel on {url}");
return new WebHostBuilder()
.UseKestrel()
.ConfigureServices(
services => services
.AddSingleton<StatefulServiceContext>(serviceContext)
.AddSingleton<IReliableStateManager>(this.StateManager))
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<Startup>()
.UseServiceFabricIntegration(listener, ServiceFabricIntegrationOptions.UseUniqueServiceUrl)
.UseUrls(url)
.Build();
}))
};
}
我应该创建一个单例类,通过DI将其连接起来,然后让DI框架将其实例传递给控制器类吗? 是否有更好的快捷方式来实现访问ParitionInfo数据的目标?
您在正确的道路上。 将参数IStatefulServicePartition
添加到MyConntroller
构造函数中。 在ConfigureServices
,使用this.Partition
注册服务分区 。
例如:
.AddSingleton<IStatefulServicePartition>(this.Partition)
