我真的不知道發生了什么我無法過濾這個查詢，試過 filter_by() 和 filter() 都回傳相同的錯誤，這可能是一個我沒有注意到的愚蠢錯誤，您的幫助將不勝感激。MariaDB(MySQL) 表結構是
-------------- -------------- ------ ----- --------- ----------------

例外是
型別錯誤：%d 格式：需要一個數字，而不是 str
在在線字串欄位上使用過濾器時
user = User.query.filter(User.api_token == token).first()
這是整個路線功能
@app.route('/api/login', methods=['GET','POST'])
def api_login():
if current_user.is_authenticated:
return "3"
token = request.args.get('apitoken', '1', type=String)
ip_ban.add(ip=request.host.split(':')[0],url=url_for('login'))
user = User.query.filter(User.api_token == token).first()
if user:
if current_user.classe == -1 :
return "-1"
if current_user.classe == 0 :
return "0"
login_user(user)
loginrec = UserLogins(user_id= user.id, login_ip= request.host.split(':')[0])
db.session.add(loginrec)
db.session.commit()
return "2"
else:

uj5u.com熱心網友回復：
發現問題，問題上線了
token = request.args.get('apitoken', '1', type=String)
正確的方法是
token = request.args.get('apitoken', '1', type=str)
