Azure應用服務上的Service Fabric客戶端。 無法加載DLL'FabricCommon.dll'

Question

我在Azure上有Service Fabric，並且有Azure App Service（ASP.NET MVC網站），它是Service Fabric微服務的客戶端。

當我運行Web應用程序時，它說：無法加載DLL'FabricCommon.dll'：找不到指定的模塊。 （來自HRESULT的異常：0x8007007E）

我已經看到生產服務器上的Azure Service Fabric缺少DLL：FabricCommon.dll，但是我不確定是否可以在azure App Service上安裝Service Fabric SDK。

這是我的客戶：

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”與標准庫“ Microsoft.ServiceFabric.Services.Wcf”中的“ WcfCommunicationClientFactory”幾乎相同，但允許我提供行為和身份

這是堆棧跟蹤：

Answer 1

為了從群集外部與SF服務進行通信，您需要在服務內部公開一個通信端點，例如WebApi或WCF或服務總線偵聽器 。

編輯：

您的代碼段使用Service Fabric Sdk（不可用）。 因此，請依靠純WCF代碼創建客戶端代理。 例如，從現有客戶端復制它。 或暴露的元數據終結像這樣並添加一個服務引用。

Answer 2

好的，我故事的棘手部分是，我不想向外界公開我的任何Service Fabric端點。 相反，我想直接使用VPN將Azure Web App鏈接到Service Fabric群集。 問題是，如果未安裝SDK，則無法使用服務結構類。 所以我現在使用HTTP API。 https://github.com/lAnubisl/ServiceFabricHttpApiClient
