# 建立使用者
<a name="create-user"></a>

您可以使用 [CreateUser](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CreateUser.html) 操作，使用提供的唯一使用者 ID 在集合中建立新使用者。然後，您可以將多個人臉與新建立的使用者相關聯。

**建立使用者 (SDK)**

1. 如果您尚未執行：

   1. 建立或更新具有 `AmazonRekognitionFullAccess` 權限的 IAM 使用者賬戶。如需詳細資訊，請參閱[步驟 1：設定 AWS 帳戶並建立使用者](setting-up.md#setting-up-iam)。

   1. 安裝和設定 AWS CLI 和 AWS SDKs。如需詳細資訊，請參閱[步驟 2：設定 AWS CLI 和 AWS SDKs](setup-awscli-sdk.md)。

1. 使用下列範例來呼叫 `CreateUser` 操作。

------
#### [ Java ]

   此 Java 程式碼範例建立一個使用者。

   ```
   import com.amazonaws.services.rekognition.AmazonRekognition;
   import com.amazonaws.services.rekognition.AmazonRekognitionClientBuilder;
   import com.amazonaws.services.rekognition.model.CreateUserRequest;
   import com.amazonaws.services.rekognition.model.CreateUserResult;
   
   
   public class CreateUser {
   
       public static void main(String[] args) throws Exception {
   
   
           AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();
   
           //Replace collectionId and userId with the name of the user that you want to create in that target collection.
   
           String collectionId = "MyCollection";
           String userId = "demoUser";
           System.out.println("Creating new user: " +
                   userId);
   
           CreateUserRequest request = new CreateUserRequest()
                   .withCollectionId(collectionId)
                   .withUserId(userId);
   
           rekognitionClient.createUser(request);
       }
   
   }
   ```

------
#### [ AWS CLI ]

   此 AWS CLI 命令會使用 CLI `create-user` 操作建立使用者。

   ```
   aws rekognition create-user --user-id {{user-id}} --collection-id {{collection-name}} --region {{region-name}}
   --client-request-token {{request-token}}
   ```

------
#### [ Python ]

   此 Python 程式碼範例建立使用者。

   import boto3
   from botocore.exceptions import ClientError
   import logging
   
   logger = logging.getLogger(__name__)
   session = boto3.Session(profile_name='profile-name')
   client = session.client('rekognition')
   
   def create_user(collection_id, user_id):
       """
       Creates a new User within a collection specified by CollectionId. 
       Takes UserId as a parameter, which is a user provided ID which 
       should be unique within the collection.
   
       :param collection_id: The ID of the collection where the indexed faces will be stored at.
       :param user_id: ID for the UserID to be created. This ID needs to be unique within the collection.
       
       :return: The indexFaces response
       """
       try:
           logger.info(f'Creating user: {collection_id}, {user_id}')
           client.create_user(
               CollectionId=collection_id,
               UserId=user_id
           )
       except ClientError:
           logger.exception(f'Failed to create user with given user id: {user_id}')
           raise
   
   def main():
       collection_id = "collection-id"
       user_id = "user-id"
       create_user(collection_id, user_id)
   
   if __name__ == "__main__":
       main()
   ```

#### [ Go ]

   此 Go 程式碼範例使用 AWS Go SDK V2，並建立使用者。

   ```
   package main
   
   import (
   	"context"
   	"fmt"
   	"log"
   
   	"github.com/aws/aws-sdk-go-v2/aws"
   	"github.com/aws/aws-sdk-go-v2/config"
   	"github.com/aws/aws-sdk-go-v2/service/rekognition"
   )
   
   func main() {
   	// Load the AWS SDK configuration
   	cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-west-2"))
   	if err != nil {
   		log.Fatalf("Failed to load configuration: %v", err)
   	}
   
   	// Create a Rekognition client
   	client := rekognition.NewFromConfig(cfg)
   
   	// Set up the input parameters
   	input := &rekognition.CreateUserInput{
   		CollectionId: aws.String("my-new-collection"), // Replace with your collection ID
   		UserId:       aws.String("user12345678910"),   // Replace with desired user ID
   	}
   
   	// Call the CreateUser operation
   	result, err := client.CreateUser(context.TODO(), input)
   	if err != nil {
   		log.Fatalf("Failed to create user: %v", err)
   	}
   
   	// Print out the results
   	fmt.Printf("User created successfully:\n")
   
   }
   ```
