服务结构指定结构URL

Question

是否可以定义服务使用哪个网址而不是标准fabric:/AppName/ServiceName？

我找不到这是否可配置或不在应用程序级别。

Answer 1

是，您可以在ApplicationManifest.xml更改服务的名称不是从服务的类名取名字以外的东西。

Short：只是将ApplicationManifest.xml中的name属性更改为其他内容。

在代码：如果我有这样的服务：

public interface IJustAnotherStatelessService : IService 
{ 
    Task<string> SayHelloAsync(string someValue); 
} 

internal sealed class JustAnotherStatelessService : StatelessService, IJustAnotherStatelessService 
{ 
    // Service implementation 
} 

注册于Program.cs这样的：

ServiceRuntime.RegisterServiceAsync("JustAnotherStatelessServiceType", 
    context => new JustAnotherStatelessService(context)).GetAwaiter().GetResult(); 

而在ServiceManifest.xml该服务

<?xml version="1.0" encoding="utf-8"?> 
<ServiceManifest ...> 
    <ServiceTypes> 
    <!-- This is the name of your ServiceType. 
     This name must match the string used in RegisterServiceType call in Program.cs. --> 
    <StatelessServiceType ServiceTypeName="JustAnotherStatelessServiceType" /> 
    </ServiceTypes> 
... 

在ApplicationManifest.xml你会得到建议的名称：

<ApplicationManifest ...> 
    <DefaultServices> 
    <Service Name="JustAnotherStatelessService"> 
     <StatelessService ServiceTypeName="JustAnotherStatelessServiceType" InstanceCount="[JustAnotherStatelessService_InstanceCount]"> 
     <SingletonPartition /> 
     </StatelessService> 
    </Service> 
    </DefaultServices> 
</ApplicationManifest> 

这会给你一个开放的，以您服务像

fabric:/app_name/JustAnotherStatelessService 

现在，继续前进，在应用程序清单更改名称：

<ApplicationManifest ...> 
    <DefaultServices> 
    <Service Name="AwesomeService"> 
     <StatelessService ServiceTypeName="JustAnotherStatelessServiceType" InstanceCount="[JustAnotherStatelessService_InstanceCount]"> 
     <SingletonPartition /> 
     </StatelessService> 
    </Service> 
    </DefaultServices> 
</ApplicationManifest> 

和您的服务现在答案来

fabric:/app_name/AwesomeService 

Answer 2

您可以使用此URI建设者从这里（ServiceUriBuilder.cs）类：https://github.com/Azure-Samples/service-fabric-dotnet-web-reference-app/blob/master/ReferenceApp/Common/ServiceUriBuilder.cs

对于无状态的服务，您可以轻松地获得代理：

var serviceUri = new ServiceUriBuilder(ServiceName); 
var proxyFactory = new ServiceProxyFactory(); 
var svc = proxyFactory.CreateServiceProxy<IServiceName>(serviceUri.ToUri()); 

对于状态服务，你必须指定分区。

var serviceUri = new ServiceUriBuilder(StatefulServiceName); 
var proxyFactory = new ServiceProxyFactory(); 
//this is just a sample of partition 1 if you are using number partitioning. 
var partition = new ServicePartitionKey(1); 
var svc = proxyFactory.CreateServiceProxy<IStatefulServiceName>(serviceUri.ToUri(), partition);
