Question

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

我无法在应用程序级别找到这是否可配置。

Answer 1

您可以从此处使用此uri构建器（ServiceUriBuilder.cs）类：https://github.com/Azure-Samples/service-fabric-dotnet-web-reference-app/blob/master/ReferenceApp/Common/ServiceUriBuilder.cs

对于无状态服务，您可以轻松获取代理：

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

对于有状态服务，您必须指定分区。

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);

是，您可以将ApplicationManifest.xml中的服务名称更改为从服务的类名中获取的名称以外的名称。

简短：只需将该服务name中的ApplicationManifest.xml属性更改为其他内容。

代码：如果我有此服务：

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

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

在此Program.cs注册：

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

在该服务的ServiceManifest.xml中

<?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中，您将获得建议的名称：

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

这将为您提供Uri服务，如

fabric:/app_name/JustAnotherStatelessService

现在，继续更改应用程序清单中的名称：

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

您的服务现在回答

fabric:/app_name/AwesomeService

Service Fabric指定结构URL
