之前那篇文章是flask+redis的，如果用flask+mysql怎么实现呢？
创建数据库：
CREATE DATABASE `web12306` DEFAULT CHARACTER SET utf8;
创建表：
CREATE TABLE `web12306` (`user_email` varchar(100) NOT NULL DEFAULT '',`user_pass` varchar(100) NOT NULL DEFAULT '',`user_name` varchar(100) NOT NULL DEFAULT '',`user_id` varchar(100) NOT NULL DEFAULT '',`user_nic` varchar(100) NOT NULL DEFAULT '',`user_phone` varchar(100) NOT NULL DEFAULT '' ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
导入数据，数据文件还是result.txt，同样的格式。
mysql -uroot -pmysql@123 -e 'load data local infile "result.txt" into table web12306.web12306 fields terminated by "---" lines terminated by "\n";'
查看数据导入情况：
数据有了，剩下还是上python代码了，使用mysql时，需要用到sqlalchemy
# -*- coding: utf-8 -*-
from flask import Flask, request, render_template, jsonify, json
from flask.ext.sqlalchemy import SQLAlchemyapp = Flask(__name__)
db = SQLAlchemy(app)app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:mysql@123@localhost/web12306'class session(db.Model):__tablename__ = 'web12306'user_id = db.Column(db.String(100), primary_key = True)user_email = db.Column(db.String(100))user_pass = db.Column(db.String(100))user_nic = db.Column(db.String(100))user_phone = db.Column(db.String(100))user_name = db.Column(db.String(100))@app.route('/scan/<user_id>', methods=['GET'])
def scan(user_id):result = session.query.filter_by(user_id=user_id).first()if result is None:json_result={'user_id':None}return json.dumps(json_result,ensure_ascii=False)else:json_result = {'user_id': result.user_id, 'user_email': result.user_email, 'user_pass': result.user_pass, 'user_nic': result.user_nic, 'user_phone': result.user_phone, 'user_name': result.user_name}return json.dumps(json_result,ensure_ascii=False)@app.route('/')
def index():return render_template('index.html')if __name__ == '__main__':app.run(host='0.0.0.0', port = 8080, debug=True)前端代码请看上一篇文字。
