flask-script

一、安装模块

pip3 install -i https://pypi.douban.com/simple flask-script

二、功能：

1.增加 runserver   重要

manage.py

from 项目名称 import create_app
from flask_script import Manager


app = create_app()
manager = Manager(app)

if __name__ == '__main__':
    # app.run()
    manager.run()

cmd命令

python manage.py runserver -h 127.0.0.1 -p 8000

2.位置传参，执行函数

from 项目名称 import create_app
from flask_script import Manager


app = create_app()
manager = Manager(app)

@manager.command
def custom(arg):
    """
    自定义命令
    python manage.py custom 123
    :param arg:
    :return:
    """
    print(arg)


if __name__ == '__main__':
    # app.run()
    manager.run()

3.关键词传参，执行函数

from chun import create_app
from flask_script import Manager


app = create_app()
manager = Manager(app)

@manager.option('-n', '--name', dest='name')
@manager.option('-u', '--url', dest='url')
def cmd(name, url):
    """
    自定义命令
    执行： python manage.py  cmd -n xx -u https://www.bilibili.com/
    :param name:
    :param url:
    :return:
    """
    print(name, url)


if __name__ == '__main__':
    # app.run()
    manager.run()
