flask入門

 

1. 簡單事例

from flask import Flask

app = Flask(__name__)

@app.route("/")
def func():
    return "Hello World"

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

2. 配置文件　　

app.config.from_object("python類或類的路徑")

app.config.from_object('pro_flask.settings.TestingConfig')

settings.py

    class Config(object):
        DEBUG = False
        TESTING = False
        DATABASE_URI = 'sqlite://:memory:'

    class ProductionConfig(Config):
        DATABASE_URI = 'mysql://user@localhost/foo'

    class DevelopmentConfig(Config):
        DEBUG = True

    class TestingConfig(Config):
        TESTING = True

PS: 從sys.path中已經存在路徑開始寫
 

PS: settings.py文件默認路徑要放在程序root_path目錄，若是instance_relative_config爲True，則就是instance_path目錄
