Laravel连接错误

Question

I've eventually made my connection with mysql instead of mssql because it was not working (I'm working with laravel). But now it's still not working. I receive the error:

SQLSTATE[3D000]: Invalid catalog name: 1046 No database selected (SQL: create table `users` (`id` int unsigned not null auto_increment primary key, `username` varchar(32) not null, `email` varchar(320) not null, `password` varchar(60) not null, `created_at` timestamp default 0 not null, `updated_at` timestamp default 0 not null) default character set utf8 collate utf8_unicode_ci)

I'm connection to my localhost with a wamp server. This is my code:

> 'mysql' => [
>             'driver'    => 'mysql',
>             'host'      => env('localhost'),
>             'database'  => env('test'),
>             'username'  => env('root'),
>             'password'  => env(''),
>             'charset'   => 'utf8',
>             'collation' => 'utf8_unicode_ci',
>             'prefix'    => '',
>             'strict'    => false,
>         ],

And my env :

'default' => env('mysql', 'mysql'),

EDIT

.env:

DB_HOST=localhost
DB_DATABASE=test
DB_USERNAME=root
DB_PASSWORD=

Answer 1

syntax env('key','default') with:

key is key before = in env file

default is default value if key not exist in env file

please edit as follows:

> 'mysql' => [
>             'driver'    => 'mysql',
>             'host'      => env('DB_HOST', 'localhost'),
>             'database'  => env('DB_DATABASE','db_name'),
>             'username'  => env('DB_USERNAME','root'),
>             'password'  => env('DB_PASSWORD',''),
>             'charset'   => 'utf8',
>             'collation' => 'utf8_unicode_ci',
>             'prefix'    => '',
>             'strict'    => false,
>         ],

P/s: excuse me my English.
