前言

  之前总是写java的crud，写的实在厌烦，因此这次写个Python的（只有查）

  1.

  2. Python代码

import pymysql
import json

from flask import Flask

app = Flask(__name__)


@app.route('/index1/<int:id>', methods=['GET'])
def indextest(id):
    # inputData = request.json.get('inputData')
    data1 = getcontent(id)
    return data1


def getcontent(inputData):
    conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='123456', db='python-mysql')  # db:表示数据库名称
    cur = conn.cursor()
    sql = "select * from book where vId='%d'" % (inputData)
    cur.execute(sql)
    data = cur.fetchone()
    print(data)
    result = {'vId': data[0], 'vN': data[1], 'cCnt': data[2]}
    return json.dumps(result, ensure_ascii=False, indent=4)


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5590)
