Python：Flask-Script通过命令行的形式来操作Flask

pip install Flask-Script

# -*- coding: utf-8 -*-
# app
from flask import Flask
app = Flask(__name__)
# manager
from flask_script import Manager, Command
manager = Manager(app)
# 1、添加不需要传递参数的命令
@manager.command
def hello():
    print("hello")
# 2、添加需要传递参数的命令
@manager.option('-n', '--name', dest='name')
def say_name(name):
    print(name)
# 3、调用方法添加
class Print(Command):
    def run(self):
        print('Print')
manager.add_command('print', Print())
if __name__ == "__main__":
    manager.run()

$ python manage.py hello
hello
$ python manage.py say_name -n Tom
Tom
$ python manage.py print
Print
