SQSContoh Amazon menggunakan SDK untuk Ruby

Contoh kode berikut menunjukkan kepada Anda cara melakukan tindakan dan mengimplementasikan skenario umum dengan menggunakan AWS SDK for Ruby With AmazonSQS.

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.

Tindakan

Contoh kode berikut menunjukkan cara menggunakanChangeMessageVisibility.
