WeChat API:er kr\u00e4ver inmatning av token, som n\u00e5s via f\u00f6ljande API<\/a> :<\/p>\n

https:\/\/api.weixin.qq.com\/cgi-bin\/token?grant_type=client_credential&appid=APPID&secret=APPSECRET<\/code><\/pre>\n
Vid framg\u00e5ng returnerar den tokenstr\u00e4ngen och utg\u00e5ngen p\u00e5 n\u00e5gra sekunder. Det finns en hastighetsgr\u00e4ns f\u00f6r att anropa detta API s\u00e5 vi m\u00e5ste cache tokenstr\u00e4ngen lokalt f\u00f6r att undvika att anropa API f\u00f6r ofta. Om token inte har g\u00e5tt ut \u00e4nnu, kommer anrop av API:et att returnera samma token.<\/p>\n
Att anropa API har n\u00e4tverkslatens och vi b\u00f6r \u00e5teranv\u00e4nda token n\u00e4r vi kan. Det b\u00e4sta s\u00e4ttet \u00e4r att cache det lokalt via databas<\/a> eller fil. F\u00f6ljande PHP-skript<\/a> kommer att kontrollera de cachade tokens som lagras och dess giltighet.<\/p>\n
