Menyebut Keaktifan Wajah APIs

Anda dapat menguji Amazon Rekognition Face Liveness dengan SDK apa pun yang AWS didukung, seperti AWS Python SDK Boto3 atau AWS SDK for Java. Anda dapat memanggil CreateFaceLivenessSession dan GetFaceLivenessSessionResults APIs dengan SDK pilihan Anda. Bagian berikut menunjukkan cara memanggil ini APIs dengan Python dan Java. SDKs

Untuk memanggil Face Liveness APIs:

• Jika Anda belum melakukannya, buat atau perbarui pengguna dengan AmazonRekognitionFullAccess izin. Untuk informasi selengkapnya, lihat Langkah 1: Mengatur akun AWS dan membuat Pengguna.

• Jika Anda belum melakukannya, instal dan konfigurasikan AWS CLI dan AWS. SDKs Untuk informasi selengkapnya, lihat Langkah 2: Mengatur AWS CLI dan AWS. SDKs

Python

Cuplikan berikut menunjukkan bagaimana Anda dapat memanggil ini APIs dalam aplikasi Python Anda. Perhatikan bahwa untuk menjalankan contoh ini Anda harus menggunakan setidaknya versi 1.26.110 dari Boto3 SDK, meskipun versi terbaru SDK direkomendasikan.

import boto3

session = boto3.Session(profile_name='default') 
client = session.client('rekognition')

def create_session():

    response = client.create_face_liveness_session()
    
    session_id = response.get("SessionId")
    print('SessionId: ' + session_id)

    return session_id
    
    
def get_session_results(session_id):

    response = client.get_face_liveness_session_results(SessionId=session_id)
    
    confidence = response.get("Confidence")
    status = response.get("Status")
    
    print('Confidence: ' + "{:.2f}".format(confidence) + "%")
    print('Status: ' + status)
    
    return status


def main():
    session_id = create_session()
    print('Created a Face Liveness Session with ID: ' + session_id)
    
    status = get_session_results(session_id)
    print('Status of Face Liveness Session: ' + status)
        

if __name__ == "__main__":
    main()
