RAM authorization

Tabel berikut menjelaskan otorisasi yang diperlukan untuk memanggil API ini. Anda dapat menentukannya dalam kebijakan Resource Access Management (RAM). Kolom pada tabel dijelaskan sebagai berikut:

Action: Aksi yang dapat digunakan dalam elemen Action pada pernyataan kebijakan izin RAM untuk memberikan izin guna melakukan operasi tersebut.
API: API yang dapat Anda panggil untuk melakukan aksi tersebut.
Access level: Tingkat akses yang telah ditentukan untuk setiap API. Nilai yang valid: create, list, get, update, dan delete.
Resource type: Jenis resource yang mendukung otorisasi untuk melakukan aksi tersebut. Ini menunjukkan apakah aksi tersebut mendukung izin tingkat resource. Resource yang ditentukan harus kompatibel dengan aksi tersebut. Jika tidak, kebijakan tersebut tidak akan berlaku.
- Untuk API dengan izin tingkat resource, jenis resource yang diperlukan ditandai dengan tanda bintang (*). Tentukan Nama Sumber Daya Alibaba Cloud (ARN) yang sesuai dalam elemen Resource pada kebijakan.
- Untuk API tanpa izin tingkat resource, ditampilkan sebagai All Resources. Gunakan tanda bintang (*) dalam elemen Resource pada kebijakan.
Condition key: Kunci kondisi yang didefinisikan oleh layanan. Kunci ini memungkinkan kontrol granular, berlaku baik hanya untuk aksi maupun untuk aksi yang terkait dengan resource tertentu. Selain kunci kondisi spesifik layanan, Alibaba Cloud menyediakan serangkaian common condition keys yang berlaku di semua layanan yang didukung RAM.
Dependent action: Aksi dependen yang diperlukan untuk menjalankan aksi tersebut. Untuk menyelesaikan aksi tersebut, pengguna RAM atau role RAM harus memiliki izin untuk melakukan semua aksi dependen.
