Function Compute：Konteks

Python 3.12

Tabel berikut menjelaskan parameter yang didukung oleh objek konteks dalam waktu proses Python 3.12.

Bidang konteks credentials telah dihapus di Python 3.12. Anda dapat menggunakan variabel lingkungan ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET, dan ALIBABA_CLOUD_SECURITY_TOKEN sebagai pengganti credentials untuk mengakses sumber daya lainnya. Untuk informasi selengkapnya, lihat Mengonfigurasi variabel lingkungan.

Kode berikut menunjukkan format objek konteks di Python 3.12.
