flask的配置文件

app

from flask import Flask, request, render_template, redirect

app = Flask(__name__)
# 配置文件这个里面写类名
app.config.from_object("settings.BaseConfig")


@app.route('/')
def index():
    return "Hello"


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

settings.py

class BaseConfig:
    DEBUG = True
    SECRET_KEY = 'dfrgthhjhgfdsfghjkhgf'


class ProdConfig(BaseConfig):
    DATABASE_URL = "mysql://[email protected]/foo"
    DEBUG = False # 这个地方把父类的给DEBUG给重写了


class QAConfig(BaseConfig):
    DATABASE_URL = "mysql://[email protected]/foo"

这种的好处 就是可以把配置文件写到这里面去
