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 SQLAlchemy app = 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。
