    'hello world'
 
    def run(self):
        print('hello world')
 
        # 自定义命令一：
 
 
manager.add_command('hello', Hello())
# 自定义命令二：
 
manager.add_command("runserver", Server())  # 命令是runserver
if __name__ == '__main__':
    manager.run()

from flask_script import Manager
from demo import app
 
manager = Manager(app)
 
 
@manager.option('-n', '--name', dest='name', help='Your name',
                default='world')  # 命令既可以用-n,也可以用--name，dest="name"用户输入的命令的名字作为参数传给了函数中的name
@manager.option('-u', '--url', dest='url',default='www.csdn.com')  # 命令既可以用-u,也可以用--url,dest="url"用户输入的命令的url作为参数传给了函数中的url
def hello(name, url):
