In diesem Artikel wird hauptsächlich die Verwendung der PHP-Version der Zahlungsschnittstellenklasse WeChat js-sdk vorgestellt und die Definition und die damit verbundenen Verwendungsfähigkeiten der PHP-Version der Zahlungsschnittstellenklasse WeChat js-sdk anhand von Beispielen analysiert Bedarf kann darauf verweisen
Diese Zahlungsklasse wird basierend auf dem offiziellen Dokument geändert! Es implementiert hauptsächlich die Generierung von JS-APIs, nativen Paketsignaturpaketen und nativen Antwortdaten im XML-Format. Kommentare sind mit dem Zweck jeder Methode gekennzeichnet. Da die Paketsignatur etwas kompliziert ist, müssen Sie mehr Zeit aufwenden, um die Dateien zu lesen und zu protokollieren, um sie einzeln zu vergleichen! Solange Sie die Tutorial-Klasse verwenden und die entsprechenden Parameter festlegen, können Sie natürlich Paketparameter usw. korrekt generieren.
