Membuat koleksi

Anda dapat menggunakan CreateCollectionoperasi untuk membuat koleksi.

Untuk informasi selengkapnya, lihat Mengelola koleksi.

Membuat koleksi (SDK)

1. Jika belum:

   1. Buat atau perbarui pengguna dengan AmazonRekognitionFullAccess izin. Untuk informasi selengkapnya, lihat Langkah 1: Siapkan akun AWS dan buat Pengguna.

   2. Instal dan konfigurasikan AWS CLI dan AWS SDK. Untuk informasi selengkapnya, lihat Langkah 2: Siapkan AWS CLI dan AWS SDK.

2. Gunakan contoh berikut untuk memanggil operasi CreateCollection.

   Java

   Contoh berikut membuat koleksi dan menampilkan Amazon Resource Name (ARN)nya.

   Ubah nilai collectionId untuk nama koleksi yang ingin Anda buat.

CreateCollection permintaan operasi

Input pada CreationCollection adalah nama koleksi yang ingin Anda buat.

{
    "CollectionId": "MyCollection"
}

CreateCollection respon operasi

Amazon Rekognition membuat koleksi dan mengembalikan Amazon Resource Name (ARN) dari koleksi yang baru dibuat.

{
   "CollectionArn": "aws:rekognition:us-east-1:acct-id:collection/examplecollection",
   "StatusCode": 200
}
