Contoh Amazon SQS menggunakan SDK for Ruby - AWS Contoh Kode SDK

Contoh Amazon SQS menggunakan SDK for Ruby

Contoh kode berikut menunjukkan cara melakukan tindakan dan menerapkan skenario umum dengan menggunakan Amazon SQS. AWS SDK for Ruby

Tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Sementara tindakan menunjukkan cara memanggil fungsi layanan individual, Anda dapat melihat tindakan dalam konteks dalam skenario terkait.

Setiap contoh menyertakan tautan ke kode sumber lengkap, di mana Anda dapat menemukan instruksi tentang cara mengatur dan menjalankan kode dalam konteks.
