salut! Aujourd'hui, je vais vous dire comment déployer un serveur pour vérifier les achats intégrés et les abonnements intégrés pour iOS et Android (validation serveur-serveur).
Sur Habré il y a un article de 2013 sur la vérification des achats par le serveur. L'article indique que la validation est principalement nécessaire pour empêcher l'accès au contenu payant à l'aide de jailbreak et d'autres logiciels. À mon avis, en 2020, ce problème n'est pas si urgent, et tout d'abord, un serveur avec vérification des achats est nécessaire pour synchroniser les achats au sein d'un même compte sur plusieurs appareils.
Il n'y a pas de difficulté technique à vérifier les reçus d'achat, en fait, le serveur «procède» simplement la demande et stocke les données d'achat.
Autrement dit, la tâche d'un tel serveur peut être divisée en 4 étapes:
- Recevoir une demande avec un reçu envoyé par l'application après l'achat
- Demande à Apple / Google pour vérification de chèque
- Sauvegarde des données de transaction
- RĂ©ponse de l'application
Dans le cadre de l'article, nous omettons le point 3, car il est purement individuel.
