python - 如何使用 Python 的 click (Command Line Interface Creation Kit) 包将变量传递给其他方法

Question

我知道它是新的，但我喜欢 click 的外观很多并且很想使用它，但我不知道如何将变量从 main 方法传递给其他方法。我是不是用错了，还是这个功能还不可用？看起来很基本，所以我确定它会在那里，但是这个东西只出了一个 little while所以也许不是。

import click

@click.option('--username', default='', help='Username')
@click.option('--password', default='', help='Password')
@click.group()
def main(**kwargs):
    print("This method has these arguments: " + str(kwargs))


@main.command('do_thingy')
def do_thing(**kwargs):
    print("This method has these arguments: " + str(kwargs))


@main.command('do_y')
def y(**kwargs):
    print("This method has these arguments: " + str(kwargs))


@main.command('do_x')
def x(**kwargs):
    print("This method has these arguments: " + str(kwargs))


main()

所以我的问题是，如何让其他方法可以使用用户名和密码选项

感谢@nathj07 为我指明了正确的方向。答案如下:

import click


class User(object):
    def __init__(self, username=None, password=None):
        self.username = username
        self.password = password


@click.group()
@click.option('--username', default='Naomi McName', help='Username')
@click.option('--password', default='b3$tP@sswerdEvar', help='Password')
@click.pass_context
def main(ctx, username, password):
    ctx.obj = User(username, password)
    print("This method has these arguments: " + str(username) + ", " + str(password))


@main.command()
@click.pass_obj
def do_thingy(ctx):
    print("This method has these arguments: " + str(ctx.username) + ", " + str(ctx.password))


@main.command()
@click.pass_obj
def do_y(ctx):
    print("This method has these arguments: " + str(ctx.username) + ", " + str(ctx.password))


@main.command()
@click.pass_obj
def do_x(ctx):
    print("This method has these arguments: " + str(ctx.username) + ", " + str(ctx.password))


main()
