在不同的 python 文件中使用 MySQL Flask 连接

Question

我有一个 app.py：

from flask import FlasK
from flask_mysqldb import MySQL


# Objeto Flask
app = Flask(__name__)

# Secret key
app.secret_key = "appLogin"

# BD config
app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'xxx'
app.config['MYSQL_PASSWORD'] = 'xxxx'
app.config['MYSQL_DB'] = 'feedlotdb'

# Obj MySQL
mysql = MySQL(app)


@app.route('/register', methods=["GET", "POST"])
def register():
   # USE BD
       sQuery = "INSERT INTO user (mail, password, name) VALUES (%s, %s, %s)"
       cur = mysql.connection.cursor()
       cur.execute(sQuery, (mail, password, name))
       mysql.connection.commit()

问题：

我把部分代码放在上面 如何获取“/Register”并将用户代码封装在 user.py 之类的文件中并使用相同的 sql.connection？ 谢谢

Answer 1

你可以创建user.py并导入mysql和app

users.py

from app import mysql
import app

from flask import Blueprint, render_template, abort

users_bp = Blueprint('users_bp', __name__)



@users_bp.route('/register', methods=["GET", "POST"])
def register():
       # USE BD
       sQuery = "INSERT INTO user (mail, password, name) VALUES (%s, %s, %s)"
       cur = mysql.connection.cursor()
       cur.execute(sQuery, (mail, password, name))
       mysql.connection.commit()

在主应用中注册蓝图：-

from users import users_bp
app.register_blueprint(users_bp, url_prefix='/users')
