func GetClient ¶

func GetClient(logger *slog.Logger, cfg *config.Config) (*http.Client, *oauth2.Token, error)

GetClient returns an authenticated http.Client and the corresponding token. It's used by the server at startup. It requires a valid, pre-existing token.

func LoadToken ¶

func LoadToken(logger *slog.Logger, cfg *config.Config) (*oauth2.Token, error)

LoadToken retrieves a token from a file, if it doesn't exist it returns a nil token.

func Login ¶

func Login(logger *slog.Logger, cfg *config.Config) error

func RevokeToken ¶

func RevokeToken(logger *slog.Logger, cfg *config.Config) error

RevokeToken securely deletes the token file. It overwrites the file with zeros to prevent recovery of the sensitive token data, then closes the file, and finally removes it from the filesystem. This approach ensures that the file is properly handled for secure deletion, particularly on systems like Windows where a file must be closed before it can be removed.
