Question

我只是弄明白MySQLdb也有conn.select_db()功能。然后，我尝试将其与Flask同时合并。这是我的代码：

from flask import Flask
from flask import request
import MySQLdb

app = Flask(__name__)

@app.route("/home")
def hello():
    return "Hello World"

# MySQL configurations
@app.route("/home/<string:db_name>/", methods=['GET'])
def db_show(db_name):
    conn = MySQLdb.connect("host","user","password")
    conn.select_db(db_name)
    cur = conn.cursor()
    sql = "SELECT user_id FROM activity_log"
    cur.execute(sql)
    data = cur.fetchone()
    return data


if __name__ == "__main__":
    app.run(debug=True)

但我有错误＆＃34; TypeError: 'long' object is not callable＆＃34;。问题：任何人都可以给我提示来修复此错误吗？或者可以按照我使用它的方式使用conn.select_db()吗？感谢

错误：

使用MySQLdb - ＆gt; conn.select_db（）与Flask
