采用python flask 开发如何管理 host port
1、#pip install flask_script 安装flask_script包
Flask-Script 是一个 Flask 扩展,为 Flask 程序添加了一个命令行解析器。Flask-Script 自带 了一组常用选项,而且还支持自定义命令。
2、在源代码中 import Manager ,代码如下：
from flask import Flask
from flask.ext.script import Manager
app = Flask(__name__)
manager = Manager(app)
@app.route('/')
def index():
return '<h1>Hello World!</h1>'
@app.route('/user/<name>')
def user(name):
return '<h1>Hello, %s!</h1>' % name
if __name__ == '__main__':
manager.run()
保存为 hello.py
3、执行 python hello.py runserver -?,结果如下
usage: flask02c.py runserver [-?] [-h HOST] [-p PORT] [--threaded]
[--processes PROCESSES] [--passthrough-errors]
[-d] [-D] [-r] [-R]
Runs the Flask development server i.e. app.run()
optional arguments:
-?, --help show this help message and exit
-h HOST, --host HOST
-p PORT, --port PORT
--threaded
--processes PROCESSES
--passthrough-errors
-d, --debug enable the Werkzeug debugger (DO NOT use in production
code)
-D, --no-debug disable the Werkzeug debugger
-r, --reload monitor Python files for changes (not 100{'const':
True, 'help': 'monitor Python files for changes (not
100% safe for production use)', 'option_strings':
['-r', '--reload'], 'dest': 'use_reloader',
'required': False, 'nargs': 0, 'choices': None,
'default': None, 'prog': 'flask02c.py runserver',
'container': <argparse._ArgumentGroup object at
0x10fe85190>, 'type': None, 'metavar': None}afe for
production use)
-R, --no-reload do not monitor Python files for changes
就可以进行相关主机与端口的指定。
