密碼錯誤導致的sqlalchemy pymysql網站連接出錯
阿新 • • 發佈：2018-10-31
Flask網站連線mariadb時提示：
sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1045, "Access denied for user 'jack'@'master' (using password: YES)")但是DBvisual連線正常：
檢視使用者發現jack在外部%訪問時和從localhost時的密碼不一樣導致的，換個密碼就對了。

Sqlalchemy的url改一下密碼就可以了
#修改jack:jackdb,jackdb是外部連線時的密碼
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://jack:[email protected]:3306/xtdt?charset=utf8'
