我正在将 Web API 服务连接到后端无状态服务。
Backservice 名为 MyProject.Management.Company,其代码为:
internal sealed class Company: StatelessService,ICompanyManagement
{
private readonly CompanyManagementImpl _impl;
public Tenents(StatelessServiceContext context, CompanyManagementImpl impl)
: base(context)
{
this._impl = impl;
}
/// <summary>
/// Optional override to create listeners (e.g., TCP, HTTP) for this service replica to handle client or user requests.
/// </summary>
/// <returns>A collection of listeners.</returns>
protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
{
return new[]
{
new ServiceInstanceListener(serviceContext => new FabricTransportServiceRemotingListener(serviceContext, this), "ServiceEndpoint")
};
}
/// <summary>
/// This is the main entry point for your service instance.
/// </summary>
/// <param name="cancellationToken">Canceled when Service Fabric needs to shut down this service instance.</param>
protected override async Task RunAsync(CancellationToken cancellationToken)
{
// TODO: Replace the following sample code with your own logic
// or remove this RunAsync override if it's not needed in your service.
long iterations = 0;
while (true)
{
cancellationToken.ThrowIfCancellationRequested();
ServiceEventSource.Current.ServiceMessage(this.Context, "Working-{0}", ++iterations);
await Task.Delay(TimeSpan.FromSeconds(1), cancellationToken);
}
}
public Task CreateCompany(Company company)
{
return _impl.CreateCompany(company);
}
public Task<List<Company>> GetAllCompanies()
{
return _impl.GetAllCompanies();
}
public Task<Company> GetCompanyById(string companyId)
{
return _impl.GetCompanyById(companyId);
}
}
代码为Listener代码,采用自This Blog Post甚至文档代码也无法编译 documentation CreateServiceRemotingListenervextension 方法不存在。
ICompanyManagement是继承自IService接口(interface)的接口(interface),通过CompanyManagament实现,该阶段仅返回静态对象。
API 名为 MyProject.Portal, Controller 代码为:
public class CompanyController : Controller
{
ICompanyManagement _proxy;
public CompanyController(StatelessServiceContext context)
{
string serviceUri = $"{context.CodePackageActivationContext.ApplicationName}" + "/MyProject.Management.Company";
_proxy = ServiceProxy.Create<ICompanyManagement>(new Uri(serviceUri));
}
// GET: api/Company
[HttpGet]
public async Task<JsonResult> Get()
{
try
{
var result = await _proxy.GetAllCompanies();
return this.Json(result);
}
catch (Exception ex)
{
throw ex;
}
}
}
当代码运行时,它返回以下错误。
NamedEndpoint 'V2Listener' not found in the address '{"Endpoints":{"ServiceEndpoint":"localhost:59286+12a705ed-11a5-4bf5-bafd-84179c966257-131719261525940414-9e876439-9294-4ec9-8b33-05f17515aaf4"}}' for partition '12a705ed-11a5-4bf5-bafd-84179c966257'
最后:我使用.netcore v2,service Fabric v6.2.274。
最佳答案
在 ICompanyManagement
中使用后立即文件添加以下行:
[assembly: FabricTransportServiceRemotingProvider(RemotingListener = RemotingListener.V2Listener, RemotingClient = RemotingClient.V2Client)]
在您的服务 ( CompanyManagement
) list ( ServiceManifest.xml
文件) 中,确保端点设置为版本 2:
<Resources>
<Endpoints>
<Endpoint Name="ServiceEndpointV2" />
</Endpoints>
</Resources>
将 CreateServiceInstanceListeners 方法更改为:
protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
{
return this.CreateServiceRemotingInstanceListeners();
}
最后在您的 Web api Controller 中注册您的服务代理,如下所示:
ICompanyManagement companyManagementClient = ServiceProxy.Create<ICompanyManagement>(new Uri($"fabric:/{applicationName}/{serviceName}"));
如果您按照以下步骤操作,它将起作用。
