Las API de WeChat requieren la entrada del token, al que se accede a trav\u00e9s de la siguiente API<\/a> :<\/p>\n

https:\/\/api.weixin.qq.com\/cgi-bin\/token?grant_type=client_credential&appid=APPID&secret=APPSECRET<\/code><\/pre>\n
En caso de \u00e9xito, devuelve la cadena del token y la caducidad en segundos. Hay un l\u00edmite de velocidad para llamar a esta API, por lo que tenemos que almacenar en cach\u00e9 la cadena del token localmente para evitar llamar a la API con demasiada frecuencia. Si el token a\u00fan no ha caducado, llamar a la API simplemente devolver\u00e1 el mismo token.<\/p>\n
Llamar a la API tiene latencia de red y debemos reutilizar el token siempre que podamos. La mejor manera es almacenarlo en cach\u00e9 localmente a trav\u00e9s de una base de datos<\/a> o un archivo. El siguiente script PHP<\/a> verificar\u00e1 los tokens en cach\u00e9 almacenados y su validez.<\/p>\n
