Azure 应用服务上的 Service Fabric 客户端。无法加载 DLL 'FabricCommon.dll'

Question

我在 Azure 上有 Service Fabric，并且 我有 Azure App Service（ASP.NET MVC 网站），它是 Service Fabric 微服务的客户端。

当我运行 Web 应用程序时，它显示：无法加载 DLL 'FabricCommon.dll'：找不到指定的模块。 （HRESULT 异常：0x8007007E）

我见过Azure Service Fabric missing DLL on production server: FabricCommon.dll，但我不确定是否可以在 azure App Service 上安装 Service Fabric SDK

这是我的客户：

var factory = new CustomWcfCommunicationClientFactory<TContract>(
                CreateDefaultNetTcpBinding(),
                endpointBehaviors: new List<IEndpointBehavior> {new StarShipEnpointBehavior(up)},
                endpointIdentity: EndpointIdentity.CreateDnsIdentity("MyIdentity"),
                exceptionHandlers: new List<IExceptionHandler> {new WcfClientExceptionHandler()},
                servicePartitionResolver: ServicePartitionResolver.GetDefault());
var serviceFabricDescription = dict[typeof(TContract)];
return new WcfCommunicationClient<TContract>(
                factory,
                serviceFabricDescription.Uri,
                ServicePartitionKey.Singleton,
                listenerName: serviceFabricDescription.ListenerName);

其中“CustomWcfCommunicationClientFactory”与标准库“Microsoft.ServiceFabric.Services.Wcf”中的“WcfCommunicationClientFactory”几乎相同，但允许我提供行为和身份

这是堆栈跟踪：

Answer 1

为了从集群外部与 SF 服务通信，您需要在服务内部公开一个通信端点，例如 WebApi 或 WCF 或 Service Bus listener。

编辑：

您的代码 sn-p 使用不可用的 Service Fabric Sdk。因此，请依赖纯 WCF 代码来创建客户端代理。例如，从现有客户端复制它。或者公开一个元数据端点，如 this 并添加一个服务引用。

Answer 2

好的，我的故事中棘手的部分是我不想将我的任何 Service Fabric 端点​​暴露给外界。相反，我想直接使用 VPN 将 Azure Web App 链接到 Service Fabric 群集。问题是我不能在没有安装 SDK 的情况下使用服务结构类。所以我现在使用 HTTP API。 https://github.com/lAnubisl/ServiceFabricHttpApiClient
