Qt中十六進制字節(jié)流轉(zhuǎn)換為Base64編碼方法是什么

//16進制字節(jié)流轉(zhuǎn)為Base64QByteArray toBase64(Base64Options options) const;QByteArray toBase64() const; // ### Qt6 merge with previous //Base64轉(zhuǎn)為16進制字節(jié)流static QByteArray fromBase64(const QByteArray &base64, Base64Options options);        static QByteArray fromBase64(const QByteArray &base64); // ### Qt6 merge with previous
