Contoh kode untuk IAM menggunakan AWS SDKs
Contoh kode berikut menunjukkan cara menggunakan IAM kit pengembangan AWS perangkat lunak (SDK).
Tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Meskipun tindakan menunjukkan cara memanggil fungsi layanan individual, Anda dapat melihat tindakan dalam konteks pada skenario terkait dan contoh lintas layanan.
Skenario adalah contoh kode yang menunjukkan cara menyelesaikan tugas tertentu dengan memanggil beberapa fungsi dalam layanan yang sama.
Untuk daftar lengkap panduan AWS SDK pengembang dan contoh kode, lihatMenggunakan layanan ini dengan AWS SDK. Topik ini juga mencakup informasi tentang memulai dan detail tentang SDK versi sebelumnya.
