GetFoundationModel 搭配 AWS SDK 使用

下列程式碼範例示範如何使用 GetFoundationModel

Java
SDK for Java 2.x
注意

GitHub 上提供更多範例。尋找完整範例,並了解如何在 AWS 程式碼範例儲存庫中設定和執行。

使用同步 Amazon Bedrock 用戶端,取得基礎模型的詳細資訊。

/** * Get details about an Amazon Bedrock foundation model. * * @param bedrockClient The service client for accessing Amazon Bedrock. * @param modelIdentifier The model identifier. * @return An object containing the foundation model's details. */ public static FoundationModelDetails getFoundationModel(BedrockClient bedrockClient, String modelIdentifier) { try { GetFoundationModelResponse response = bedrockClient.getFoundationModel( r -> r.modelIdentifier(modelIdentifier) ); FoundationModelDetails model = response.modelDetails(); System.out.println(" Model ID: " + model.modelId()); System.out.println(" Model ARN: " + model.modelArn()); System.out.println(" Model Name: " + model.modelName()); System.out.println(" Provider Name: " + model.providerName()); System.out.println(" Lifecycle status: " + model.modelLifecycle().statusAsString()); System.out.println(" Input modalities: " + model.inputModalities()); System.out.println(" Output modalities: " + model.outputModalities()); System.out.println(" Supported customizations: " + model.customizationsSupported()); System.out.println(" Supported inference types: " + model.inferenceTypesSupported()); System.out.println(" Response streaming supported: " + model.responseStreamingSupported()); return model; } catch (ValidationException e) { throw new IllegalArgumentException(e.getMessage()); } catch (SdkException e) { System.err.println(e.getMessage()); throw new RuntimeException(e); } }

使用非同步 Amazon Bedrock 用戶端,取得基礎模型的詳細資訊。

/** * Get details about an Amazon Bedrock foundation model. * * @param bedrockClient The async service client for accessing Amazon Bedrock. * @param modelIdentifier The model identifier. * @return An object containing the foundation model's details. */ public static FoundationModelDetails getFoundationModel(BedrockAsyncClient bedrockClient, String modelIdentifier) { try { CompletableFuture<GetFoundationModelResponse> future = bedrockClient.getFoundationModel( r -> r.modelIdentifier(modelIdentifier) ); FoundationModelDetails model = future.get().modelDetails(); System.out.println(" Model ID: " + model.modelId()); System.out.println(" Model ARN: " + model.modelArn()); System.out.println(" Model Name: " + model.modelName()); System.out.println(" Provider Name: " + model.providerName()); System.out.println(" Lifecycle status: " + model.modelLifecycle().statusAsString()); System.out.println(" Input modalities: " + model.inputModalities()); System.out.println(" Output modalities: " + model.outputModalities()); System.out.println(" Supported customizations: " + model.customizationsSupported()); System.out.println(" Supported inference types: " + model.inferenceTypesSupported()); System.out.println(" Response streaming supported: " + model.responseStreamingSupported()); return model; } catch (ExecutionException e) { if (e.getMessage().contains("ValidationException")) { throw new IllegalArgumentException(e.getMessage()); } else { System.err.println(e.getMessage()); throw new RuntimeException(e); } } catch (InterruptedException e) { Thread.currentThread().interrupt(); System.err.println(e.getMessage()); throw new RuntimeException(e); } }
