Interfejsy API WeChat wymagaj\u0105 wprowadzenia tokena, do kt\u00f3rego dost\u0119p uzyskuje si\u0119 za po\u015brednictwem nast\u0119puj\u0105cego interfejsu API<\/a> :<\/p>\n

Po pomy\u015blnym zako\u0144czeniu zwraca ci\u0105g tokena i wyga\u015bni\u0119cie w sekundach. Istnieje limit szybko\u015bci wywo\u0142ywania tego interfejsu API, wi\u0119c musimy buforowa\u0107 ci\u0105g tokena lokalnie, aby unikn\u0105\u0107 zbyt cz\u0119stego wywo\u0142ywania interfejsu API. Je\u015bli token jeszcze nie wygas\u0142, wywo\u0142anie API po prostu zwr\u00f3ci ten sam token.<\/p>\n
Wywo\u0142anie API ma op\u00f3\u017anienie sieci i powinni\u015bmy ponownie u\u017cy\u0107 tokena, kiedy tylko mo\u017cemy. Najlepszym sposobem jest buforowanie go lokalnie za po\u015brednictwem bazy danych<\/a> lub pliku.
