密码输错了。
密码输错了。 帮我看看,我如果直接用root,不加密码也报错,我建了一个用户,但是密码是加密的,加密之前是manager,看我写的有什么问题吗?谢谢
密码输错了。
用root 怎么会报错,你的root有密码吗。
在dos命令行下用system登陆看能不能登陆。
select password('manager')

口令应该没有错
不过这个 systme 用户什么权限都没有(看到的权限设置都是 N),就算是连上了也没用
root 用户没有口令
mysql_connect('localhost', 'root', '');
应该可以
select password('manager')

我数据库name字段是varchar类型的,我现在插入她让我必须插入字符串类型。我这个不是字符串类型么?
name 字段的其他属性是怎样的? 默认值是不为null吗?有唯一索引吗?
name 字段的其他属性是怎样的? 默认值是不为null吗?有唯一索引吗? 没有其他字段了,就一个name,因为我插入老是不对,所以我id都没用
设置的有问题

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3.

Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
