Php SQLSTATE[HY000][1698]-Laravel-6.5.1

我创建了一个新的laravel项目，更改了应用程序密钥以及.env和database.php文件中的数据库数据

以下是.env：

APP_NAME=NewSite
APP_ENV=local
APP_KEY=base64:Sh8WFAEfaUTDadmmpFiTDE8gbgUAOm7zgIywx8ZKRUo=
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=NewSite
DB_USERNAME=NewSite
DB_PASSWORD=NewSite

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

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=mt1

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"

这是database.php文件：

<?php

];

当数据库中的所有变量都是默认的laravel格式，例如

env（'DB_database'，'forge'）

时，我也尝试了

php artisan migrate

，但仍然出现了相同的错误

我尝试了：

php artisan缓存：clear

，

php artisan视图：cache

，

php artisan视图：clear

，但这并没有解决问题，它仍然将laravel作为数据库，root作为数据库用户，以及“”作为连接器中的密码。php

请提供任何帮助

您不需要更改任何代码。更改.env文件后，需要运行：

• php artisan配置：清除
• php artisan缓存：清除
• php artisan配置：缓存

---

运行这些命令并修复它

*如果编辑.env并再次尝试运行php artisan Service，请关闭服务器*

如果不工作！ 然后尝试以下操作：

在Database.php中

将严格的true改为false。使用以下方法：

    'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'NewSite'),
            'username' => env('DB_USERNAME', 'NewSite'),
            'password' => env('DB_PASSWORD', 'NewSite'),
            'unix_socket' => env('DB_SOCKET', ''),

当您修改.env值时，您的服务器是否在运行？@MehediHassan抱歉，我需要重新检查这可能是问题所在solution@MehediHassan谢谢那是真的解决方案当您修改.env值时，您的服务器是否正在运行？@MehediHassan抱歉，我需要重新检查，这可能是问题所在solution@MehediHassan谢谢，这是真正的解决方案每次你编辑你的.env你必须停止并再次运行服务器。否则不会产生任何效果。每次编辑.env时，必须停止并再次运行服务器。否则不会有任何效果。
