Flask网站连接mariadb时提示：
sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1045, "Access denied for user 'jack'@'master' (using password: YES)")
但是DBvisual连接正常：
查看用户发现jack在外部%访问时和从localhost时的密码不一样导致的，换个密码就对了。

Sqlalchemy的url改一下密码就可以了
#修改jack:jackdb,jackdb是外部连接时的密码
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://jack:[email protected]:3306/xtdt?charset=utf8'
