我以某种方式无法将我的 pyhton 应用程序连接到本地主机上的新 MySQL 服务器。密码好像可以,我可以登录,但应用程序不能。
赠款:
mysql> show grants for test@localhost;
+-------------------------------------------------------------------------------+
| Grants for test@localhost |
+-------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `test`@`localhost` |
| GRANT SELECT, INSERT, UPDATE, DELETE ON `Project`.* TO `test`@`localhost` |
+-------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

2021-02-11T10:49:13.897736Z 10 Connect Access denied for user 'test'@'localhost' (using password: YES)
但是,我可以从 CLI 连接:
$ mysql -u test -p
Enter password:

密码包含以下字符串:42$7&Z
,长度为 16 个字符。
我现在设置了:default_authentication_plugin= mysql_native_password
,但仍然没有变化。
来自 Python 3.8 的连接(适用于其他服务器):
def create_connection(self):
settings = get_project_settings()
self.conn = mysql.connector.connect(
host=settings.get('MYSQL_SERVER'),
user=settings.get('MYSQL_USER'),
passwd=settings.get('MYSQL_PW'),
database=settings.get('MYSQL_DB'),
charset='utf8'
)
self.conn._time_zone = '+00:00'
self.conn.autocommit = True
self.curr = self.conn.cursor()
self.curb = self.conn.cursor(buffered=True)
有什么我忽略的地方吗?

尝试删除 MySQL 'test'@'localhost'
用户并重新创建它(如下说明)。然后授予权限并且不使用get_project_settings()
。只需输入 str
值。
要重新创建用户,请运行以下命令:
DROP USER 'test'@'localhost';
CREATE USER 'test'@'localhost' IDENTIFIED BY 'password'
这是带有 str
值的修改后的代码(如果可行,请检查您的配置并使用您的代码重试):
def create_connection(self):
self.conn = mysql.connector.connect(
host='localhost',
user='test',
password='password,
database='database',
charset='utf8'
)
self.conn._time_zone = '+00:00'
self.conn.autocommit = True
self.curr = self.conn.cursor()
self.curb = self.conn.cursor(buffered=True)
