我試圖通過localhost運行基於流明的查詢。我不知道如何正確調用正確的數據庫名稱。如何在PHP Laravel Lumen中建立與數據庫的連接？
編輯：我收到以下錯誤的原因是因爲數據庫名稱的在我的項目我的.env文件的名稱。我的.env文件中的DB_DATABASE=mydbschemaname行需要有我的數據庫名稱，但是如何找到該文件？我無法在任何地方找到它。
代碼我有如下，routes.php位於APP->的Http：
$app->get('/records', '[email protected]');
在APP-> HTTP- UserController.php>控制器：
namespace App\Http\Controllers;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class UserController extends Controller
{
public function index() {
$users = User::all();
return response()->json($users);
}
}
User.php in app-> Http：
namespace App;
use Illuminate\Auth\Authenticatable;
use Laravel\Lumen\Auth\Authorizable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
class User extends Model implements
AuthenticatableContract,
AuthorizableContract
{
use Authenticatable, Authorizable;
protected $fillable = [
'name', 'email',
];
protected $hidden = [
'password',
];
}
在APP->數據庫 - >遷移[date]_create_users_table.php：
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name', 200);
$table->string('email', 200)->unique();
$table->string('password', 200);
$table->timestamps();
});
DB::table('users')->insert(
['id' => 1, 'name' => 'example', 'email' => '[email protected]', 'password' => 'thisisthepassword', 'updated_at' => '2015-10-15 01:23:45', 'created_at' => '2015-10-15 01:23:45']
);
}
public function down()
{
Schema::drop('users');
}
}
然後當然，我有位於所述database.php APP->於供應商> laravel->內腔框架 - >配置：
<?php

最後，這裏是我的.env文件所在的文件夾的應用程序之外，在根項目文件夾：
APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomKey!!!
APP_LOCALE=en
APP_FALLBACK_LOCALE=en
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=database
DB_USERNAME=homestead
DB_PASSWORD=secret
CACHE_DRIVER=memcached
SESSION_DRIVER=memcached
QUEUE_DRIVER=database
我假設這是最後一個文件（.env），我必須更改DB_DATABASE名稱，但我不完全確定。任何幫助，將不勝感激。
僅供參考：此處的最終結果是能夠連接到數據庫並顯示我在用戶表中添加的用戶的記錄。
是的，你需要在'.env'文件中設置連接信息到你的數據庫。 – patricus
@patricus我明白這一點。我不知道我的數據庫的名稱，因此我無法連接。有沒有辦法找到這個？ – NoReceipt4Panda
您有責任創建數據庫。創建數據庫後，使用連接信息（例如您創建的數據庫的名稱）更新'.env'文件，然後運行遷移（'php artisan migrate'）在數據庫中創建表。 – patricus
