(HY000/1045)：使用 Windows 拒絕用戶 'root'@'localhost'（使用密碼：YES）的訪問

Question

我無法登錄到 MySQL 服務器。 這是我收到的錯誤消息“無法登錄到 MySQL 服務器”“mysqli::real_connect(): (HY000/1045): 用戶 'root'@'localhost' 的訪問被拒絕（使用密碼：是）”

這是我的 database.php 文件

<?php

    ],

];

我嘗試使用 null 密碼（完全沒有字符）登錄，但我的所有數據庫中都出現“#1932 - 表‘my_table_name’在引擎中不存在”。

有人可以幫幫我嗎？。 謝謝你

如果您沒有在單引號中指定數據庫名稱，那么您必須在 ENV 中用單引號指定您的數據庫用戶名，例如

DB_USERNAME='root@localhost'

也許有用
