Esempi di Lambda con SDK per SAP ABAP
I seguenti esempi di codice mostrano come eseguire azioni e implementare scenari comuni utilizzando l' AWS SDK per SAP ABAP con Lambda.
Le nozioni di base sono esempi di codice che mostrano come eseguire le operazioni essenziali all'interno di un servizio.
Le operazioni sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le operazioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati.
Ogni esempio include un collegamento al codice sorgente completo, in cui è possibile trovare istruzioni su come configurare ed eseguire il codice nel contesto.
Argomenti
Nozioni di base
L'esempio di codice seguente mostra come:
Crea un ruolo IAM e una funzione Lambda, quindi carica il codice del gestore.
Richiamare la funzione con un singolo parametro e ottenere i risultati.
Aggiorna il codice della funzione e configuralo con una variabile di ambiente.
Richiamare la funzione con nuovi parametri e ottenere i risultati. Visualizza il log di esecuzione restituito.
Elenca le funzioni dell'account, quindi elimina le risorse.
Per ulteriori informazioni sull'utilizzo di Lambda, consulta Creare una funzione Lambda con la console.
