Python Click: Having the group execute code AFTER a command

问题

I have a click.group() defined, with about 10 commands in it. I understand how to use a group to run code before the code in the command, but I also want to run some code AFTER each command is run. Is that possible with click?

回答1:

You can use @resultcallback decorator

@click.group()
def cli():
    click.echo('Before command')


@cli.resultcallback()
def process_result(result, **kwargs):
    click.echo('After command')


@cli.command()
def command():
    click.echo('Command')


if __name__ == '__main__':
    cli()

>> python cli.py command
>> Before command
>> Command
>> After command
