bootstrap+flask+mysql实现网站查询-原创手记-慕课网

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)
