使用flask查询MysqL数据库，发布http+json对外接口
from flask import Flask
import pyMysqL
import json
#初始化flask对象
app = Flask(__name__)
#获取数据库链接信息
def get_conn():
return pyMysqL.connect(
host = '192.168.*.*',
user = 'root',
password = '12345',
port = 3306,
db = 't3',
charset = 'utf8',
autocommit = True
)
#获取数据库查询结果
def query_MysqL_data(data_id):
conn = get_conn()
sql = """
select * from u where id = %s
"""
cursor = conn.cursor()
cursor.execute(sql,(data_id,))
conn.close()
return cursor.fetchall()
#接口网址，可通过修改data_id值，获取不同的结果
@app.route('/query_data/<data_id>')
def hello_world():
return json.dumps(
query_MysqL_data()
)
if __name__ == '__main__':
app.run()
