Question

当我在名为 000webhostapp.com 的免费主机上部署我的Laravel项目时，我收到了这个错误：

SQLSTATE [HY000] [2002]拒绝连接（SQL：select * from is a 按posts desc limit 10）订购

我尝试在那里创建一个数据库，并且我还连接了phpmyadmin。

我的config / database.php文件是：

created_at

我的.env文件是：

    <?php

return [

    /*

如果有人能解决我的问题，欢迎你。感谢

Answer 1

Please use the following

'mysql' => [
   'driver' => 'mysql',
   'host' => env('DB_HOST', '127.0.0.1'),
   'port' => env('DB_PORT', '3306'),
   'database' => env('DB_DATABASE', ''),
   'username' => env('DB_USERNAME', ''),
   'password' => env('DB_PASSWORD', ''),
   'unix_socket' => env('DB_SOCKET', ''),
   'charset' => 'utf8mb4',
   'collation' => 'utf8mb4_unicode_ci',
   'prefix' => '',
   'strict' => true,
   'engine' => null,
        ],

and in env file

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=id5155399_laravel
DB_USERNAME=id5155399_victorhugo
DB_PASSWORD=ay942006

Answer 2

配置/ database.php中

    'mysql' => [
       'driver' => 'mysql',
       'host' => env('DB_HOST', '127.0.0.1'),
       'port' => env('DB_PORT', '3306'),
       'database' => env('DB_DATABASE', ''),
       'username' => env('DB_USERNAME', ''),
       'password' => env('DB_PASSWORD', ''),
       'unix_socket' => env('DB_SOCKET', ''),
       'charset' => 'utf8mb4',
       'collation' => 'utf8mb4_unicode_ci',
       'prefix' => '',
       'strict' => true,
       'engine' => null,
       'options'=> [PDO::ATTR_EMULATE_PREPARES => true,]
            ],

并在env文件中

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=id5155399_laravel
DB_USERNAME=id5155399_victorhugo
DB_PASSWORD=ay942006

从这里复制粘贴，让我知道它是否有效！

在PagesController.php中，您可以更改

$posts = Post::orderBy('created_at', 'desc')->limit(10)->get();

到

$posts = Post::latest()->limit(10)->get();

在免费主机上部署Laravel项目时出错（000webhostapp.com）
