[MySQL] bootstrap+flask+mysql实现网站查询

数据库 数据库 发布于:2021-07-03 21:47 | 阅读数:514 | 评论:0

  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。
