Exemple PHP - Connexion tierce à WeChat

L'éditeur ci-dessous vous proposera une démo de connexion tierce (native) WeChat [à lire absolument]. L'éditeur le trouve plutôt bon, je vais donc le partager avec vous maintenant et le donner comme référence pour tout le monde. Suivons l'éditeur et jetons un coup d'œil.

Je travaille dans une boutique en ligne depuis un certain temps. L'entreprise espère développer ses propres produits et forme de nouvelles personnes.

Récemment, je dois me connecter moi-même à WeChat. J'ai écrit la connexion tierce native de WeChat basée sur le framework ectore pour me familiariser avec la connexion tierce de WeChat et l'écrire sur ecstore.

Une démo simple, pas très bonne, je souhaite la partager avec vous, en espérant qu'elle puisse apporter des idées à des amis qui souhaitent se connecter en tant que tiers à WeChat...
