TypeError：'連接'對象在Python中使用mysqldb無法調用

Question

from flask import Flask 
from flask_restful import Resource, Api 
from flask_restful import reqparse 
from flask_mysqldb import MySQL 



mysql = MySQL()

       cursor = conn.cursor() 
       cursor.callproc('spCreateUser',(_userEmail,_userPassword)) 
       data = cursor.fetchall() 

       if len(data) is 0: 
        conn.commit() 
        return {'StatusCode':'200','Message': 'User creation success'} 
       else: 
        return {'StatusCode':'1000','Message': str(data[0])} 

      except Exception as e: 
       return {'error': str(e)} 



    api.add_resource(CreateUser, '/CreateUser') 
    api.add_resource(AuthenticateUser, '/AuthenticateUser') 
    api.add_resource(AddItem, '/AddItem') 
    api.add_resource(GetAllItems, '/GetAllItems') 

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

它引發錯誤「連接對象不可調用」。 我已經在@stackoverflow中查找過所有可能的問題，但無法找到相同的解決方案..如果有人有解決方案，請幫助我。 謝謝。

注：現在這個代碼工作...謝謝你

更換

conn = mysql.connect() 
cursor = conn.cursor() 

與

conn = mysql.connection 
cursor = conn.cursor()
