python - 使用 python 的谷歌应用程序引擎中的服务器内部错误

Question

import webapp2
import mysql.connector

class MainHandler(webapp2.RequestHandler):
    def get(self):
        db=mysql.connector.connect(host="localhost",user="root",password="bsit",database="registration")
        mycursor=db.cursor()
        mycursor.execute("select * from student")
        result=mycursor.fetchall()
        self.response.write(str(result))

app = webapp2.WSGIApplication([('/', MainHandler)], debug=True)

内部服务器错误服务器出错或无法执行请求的操作。
