flask的脚本控制flask_script

flask_script用法:

#_*_ encoding: utf-8 _*_   @author: ty  hery   2019/1/12
from flask_script import Manager
from flask import Flask
import sqlite3

app = Flask(__name__)
manager = Manager(app)


@manager.command
def hello():
    print('hello world')

@manager.option('-m','--msg',dest='msg_val',default='world') # -m :参数  default:默认参数
def hello_world(msg_val):
    print('hello ' + msg_val)

@manager.command
def init_db():
    sql = 'create table user (id INT,name TEXT)'
    conn = sqlite3.connect("flask_test.db")
    cursor = conn.cursor()
    cursor.execute(sql)
    conn.commit()
    cursor.close()
    conn.close()

if __name__ == "__main__":
    manager.run()

在该文件同等级目录下: python manager.py hello  打印出 hello world
python manager.py hello  打印出 hello world

(py2_for_websocket) X:\python3.64\Flask>python manager.py  hello_world   运行 hello world函数不带参数,使用默认参数, 
hello world

(py2_for_websocket) X:\python3.64\Flask>python manager.py  hello_world  -m jikexueyuan  运行 hello world函数带参数jikexueyuan 
hello jikexueyuan

(py2_for_websocket) X:\python3.64\Flask>python manager.py  init_db    # 在当前目录下新建了flask_test.db文件

#_*_ encoding: utf-8 _*_   @author: ty  hery   2019/12/20

from  flask import  Flask, session, current_app, g
from flask_script import Manager   # 启动命令的管理器类

app = Flask(__name__)

# 创建Manager管理器类的对象
manager = Manager(app)


@app.route('/index')
def index():
    print('index 被执行')
    return 'index page'


if __name__ == '__main__':
    # print('--哈哈01--',app.url_map,'--哈哈01--')
    # app.run(debug=True)
    # app.run(debug=False)

    # 通过管理器对象来启动flask
    manager.run()

可以在这个文件所在目录下 运行: python 10_flask_script.py runserver -h 127.0.0.1 -p 5000
启动项目文件方式: -d指的是开启debug模式 在 X:\python3.64\anzhuangweizhi目录(pyhton3.6的默认环境下启动python
python X:/python3.64/Flask/jikexueyuan_flask/10_flask_script.py runserver - h 0.0.0.0 - p 8000 - d

X:\python3.64\Flask\flask类视图和restful>python 10_flask_script.py runserver -h 127.0.0.1 -p 5000 启动命令
