SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO)

Question

报错提示：SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: select * from blog_user where username = bb)

建立了一个bolg_user的数据库表，有用户名和密码的，然后我登陆显示这个错误，是什么问题，该如何解决？谢谢
附上我的.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=blog
DB_USERNAME=root
DB_PASSWORD=

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

Answer 1

对于用户'root'@'localhost',无密码登录时,权限不足以执行该操作(SQL: select * from blog_user where username = bb)

可以尝试带密码登录
