建立集合

若要建立集合 (SDK)

1. 如果您尚未執行：

   1. 建立或更新具有 AmazonRekognitionFullAccess 許可的使用者。如需詳細資訊，請參閱步驟 1：設定AWS帳戶並建立使用者。

   2. 安裝並設定 AWS CLI 和 AWS SDKs. 如需詳細資訊，請參閱步驟 2：設定 AWS CLI 以及 AWS SDKs。

2. 使用下列範例來呼叫 CreateCollection 操作。

   Java

   下列範例會建立集合並顯示其 Amazon 資源名稱 (ARN)。

   將 collectionId 的值變更為您要建立集合的名稱。

   public class CreateCollection {
   
      public static void main(String[] args) throws Exception {
   
   
         AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();
   
         
         String collectionId = "MyCollection";
               System.out.println("Creating collection: " +
            collectionId );
               
           CreateCollectionRequest request = new CreateCollectionRequest()
                       .withCollectionId(collectionId);
              
         CreateCollectionResult createCollectionResult = rekognitionClient.createCollection(request); 
         System.out.println("CollectionArn : " +
            createCollectionResult.getCollectionArn());
         System.out.println("Status code : " +
            createCollectionResult.getStatusCode().toString());
   
      } 
   
   }
       
   
   

   Java V2

   此代碼取自 AWS 文檔SDK示例 GitHub 存儲庫。請參閱此處的完整範例。

   將建立 Rekognition 工作階段的行中 profile_name 值取代為您開發人員設定檔的名稱。

   AWS CLI

   此 AWS CLI 指令會顯示create-collectionCLI作業的JSON輸出。

   將 collection-id 的值取代為您要建立集合的名稱。

   使用您開發人員設定檔的名稱取代 profile_name 的值。

   aws rekognition create-collection --profile profile-name --collection-id "collection-name"

   Python

   下列範例會建立集合並顯示其 Amazon 資源名稱 (ARN)。

   將 collection_id 的值變更為您要建立集合的名稱。將建立 Rekognition 工作階段的行中 profile_name 值取代為您開發人員設定檔的名稱。
