WeChat-sovellusliittym\u00e4t vaativat tunnuksen sy\u00f6tteen, jota k\u00e4ytet\u00e4\u00e4n seuraavan API<\/a> :n kautta :<\/p>\n

https:\/\/api.weixin.qq.com\/cgi-bin\/token?grant_type=client_credential&appid=APPID&secret=APPSECRET<\/code><\/pre>\n
Onnistuessaan se palauttaa merkkijonon ja vanhenemisen sekunneissa. T\u00e4m\u00e4n API:n kutsumisessa on nopeusrajoitus, joten meid\u00e4n on tallennettava merkkijono paikallisesti v\u00e4limuistiin, jotta v\u00e4ltyt\u00e4\u00e4n sovellusliittym\u00e4n kutsumiselta liian usein. Jos tunnus ei ole viel\u00e4 vanhentunut, API:n kutsuminen palauttaa saman tunnuksen.<\/p>\n
Soittosovellusliittym\u00e4ll\u00e4 on verkkoviive, ja meid\u00e4n tulee k\u00e4ytt\u00e4\u00e4 tunnusta uudelleen aina, kun voimme. Paras tapa on tallentaa se v\u00e4limuistiin paikallisesti tietokannan<\/a> tai tiedoston kautta. Seuraava PHP-skripti<\/a> tarkistaa v\u00e4limuistissa olevat tunnukset ja niiden kelpoisuuden.<\/p>\n
