Les API WeChat n\u00e9cessitent la saisie du jeton, accessible via l’ API<\/a> suivante\u00a0:<\/p>\n

https:\/\/api.weixin.qq.com\/cgi-bin\/token?grant_type=client_credential&appid=APPID&secret=APPSECRET<\/code><\/pre>\n
En cas de succ\u00e8s, il renvoie la cha\u00eene de jeton et l’expiration en secondes. Il existe une limite de d\u00e9bit pour appeler cette API, nous devons donc mettre en cache la cha\u00eene de jeton localement pour \u00e9viter d’appeler l’API trop fr\u00e9quemment. Si le jeton n’a pas encore expir\u00e9, l’appel de l’API renverra simplement le m\u00eame jeton.<\/p>\n
L’API d’appel a une latence de r\u00e9seau et nous devons r\u00e9utiliser le jeton chaque fois que nous le pouvons. Le meilleur moyen est de le mettre en cache localement via une base de donn\u00e9es<\/a> ou un fichier. Le script PHP<\/a> suivant v\u00e9rifiera les jetons en cache stock\u00e9s et leur validit\u00e9.<\/p>\n
