我正在尝试通过localhost. 我不知道如何正确调用正确的数据库名称。
编辑：我收到以下错误的原因是因为 .env 我的项目文件中的数据库名称的名称。DB_DATABASE=mydbschemaname我的文件中的行.env需要有我的数据库名称，但我该如何找到呢？我在任何地方都找不到它。
我的代码如下，routes.php位于app->Http：
$app->get('/records', 'UserController@index');
UserController.php在应用程序-> Http-> 控制器中：
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在应用程序-> Http 中：
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',
];
}
[date]_create_users_table.php在应用程序-> 数据库-> 迁移中：
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' => 'example@example.com', 'password' => 'thisisthepassword', 'updated_at' => '2015-10-15 01:23:45', 'created_at' => '2015-10-15 01:23:45']
);
}
public function down()
{
Schema::drop('users');
}
}
然后当然，我有database.php位于 app->vendor->laravel->lumen-framework->config 中：
<?php

最后，这是我的.env文件位于根项目文件夹中的 app 文件夹之外：
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
我假设这.env是我必须更改DB_DATABASE名称的最后一个文件 ( )，但我不完全确定。任何帮助，将不胜感激。
仅供参考：这里的最终结果是能够连接到数据库并为我添加到用户表中的用户显示该记录。
