Python的瓶 - 類型錯誤：需要一個整數（有型STR）

Question

我建立一個簡單的web應用程序在Python瓶，但是當我試圖提交表單，我收到此錯誤信息 -

「類型錯誤：需要一個整數（有型STR）」

from flask import Flask, render_template, request, flash, redirect, url_for, session, logging 
from data import Articles 
from flask_mysqldb import MySQL

if __name__ == '__main__': 
    app.secret_key = 'secret123' 
    app.run(debug=True)

我不知道爲什麼發生這種情況，任何人都可以指導我在此請。我看了看這裏的其他解決方案，但他們並沒有真正對我

工作在配置參數端口必須是整數 你在這裏傳遞的字符串

#Config MySQL 
app.config['MYSQL_PORT'] = '8889' ##pass 8889 instead of '8889'
