在我的 .env 文件中，我有两个变量
App_id: 12345
App_secret: abc123
但是我想知道是否有一种方法可以使如果用户userNo2登录，它将代替使用
App_id: 45678
App_secret: abc456
是否有一种方法可以根据用户在env文件中具有 if / else 功能？
答案 0 :(得分：1)
是的，它是Possibel，但不是 .env
您可以将逻辑移至中间件
第1步：创建新的中间件
php artisan make:middleware SetAppConfigForUserMiddleware
因此，现在将在以下位置创建名为SetAppConfigForUserMiddleware.php的新文件
Project \ app \ Http \ Middleware
步骤：2在配置中添加默认配置变量
打开您的Project\app\Config\app.php，在其中添加默认变量
<?php
return [
'APP_ID' => '45678', 'APP_SECRET' => 'abc456',
/*
|--------------------------------------------------------------------------
| Application Name
|--------------------------------------------------------------------------
|
| This value is the name of your application. This value is used when the
| framework needs to place the application's name in a notification or
| any other location as required by the application or its packages.
|
*/
'name' => env('APP_NAME', 'Laravel'),
/*
|--------------------------------------------------------------------------
| Application Environment
|--------------------------------------------------------------------------
|
| This value determines the "environment" your application is currently
| running in. This may determine how you prefer to configure various
| services the application utilizes. Set this in your ".env" file.
|
*/
'env' => env('APP_ENV', 'production'),
/*
|--------------------------------------------------------------------------
| Application Debug Mode
|--------------------------------------------------------------------------
|
| When your application is in debug mode, detailed error messages with
| stack traces will be shown on every error that occurs within your
| application. If disabled, a simple generic error page is shown.
|
*/
'debug' => env('APP_DEBUG', false),
/*
|--------------------------------------------------------------------------
| Application URL
|--------------------------------------------------------------------------
|
| This URL is used by the console to properly generate URLs when using
| the Artisan command line tool. You should set this to the root of
| your application so that it is used when running Artisan tasks.
|
*/
'url' => env('APP_URL', 'http://localhost'),
'asset_url' => env('ASSET_URL', null),
/*
|--------------------------------------------------------------------------
| Application Timezone
|--------------------------------------------------------------------------
|
| Here you may specify the default timezone for your application, which
| will be used by the PHP date and date-time functions. We have gone
| ahead and set this to a sensible default for you out of the box.
|
*/
'timezone' => 'UTC',
/*
|--------------------------------------------------------------------------
| Application Locale Configuration
|--------------------------------------------------------------------------
|
| The application locale determines the default locale that will be used
| by the translation service provider. You are free to set this value
| to any of the locales which will be supported by the application.
|
*/
'locale' => 'en',
/*
|--------------------------------------------------------------------------
| Application Fallback Locale
|--------------------------------------------------------------------------
|
| The fallback locale determines the locale to use when the current one
| is not available. You may change the value to correspond to any of
| the language folders that are provided through your application.
|
*/
'fallback_locale' => 'en',
/*
|--------------------------------------------------------------------------
| Faker Locale
|--------------------------------------------------------------------------
|
| This locale will be used by the Faker PHP library when generating fake
| data for your database seeds. For example, this will be used to get
| localized telephone numbers, street address information and more.
|
*/
'faker_locale' => 'en_US',
/*
|--------------------------------------------------------------------------
| Encryption Key
|--------------------------------------------------------------------------
|
| This key is used by the Illuminate encrypter service and should be set
| to a random, 32 character string, otherwise these encrypted strings
| will not be safe. Please do this before deploying an application!
|
*/
'key' => env('APP_KEY'),
'cipher' => 'AES-256-CBC',
/*
|--------------------------------------------------------------------------
| Autoloaded Service Providers
|--------------------------------------------------------------------------
|
| The service providers listed here will be automatically loaded on the
| request to your application. Feel free to add your own services to
| this array to grant expanded functionality to your applications.

'providers' => [

第3步：在SetAppConfigForUserMiddleware中间件上设置配置
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Config;
class SetAppConfigForUserMiddleware
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$authorizedUser = Auth::user();
if (! App::runningInConsole() && ! is_null($authorizedUser)) {
Config::set('app.APP_ID','appidOfUser'.Auth()->user()->name);
Config::set('app.APP_SECRET', 'appsecretOfUser'.Auth()->user()->email);
}
return $next($request);
}
}
第4步：将中间件添加到Kernal.php
如果您需要在所有网络路由中为用户设置此配置，则可以按照以下步骤进行
打开文件Project / app / Http / kernal.php
您将找到受$middlewareGroups 受保护的属性数组
您可以添加到它
/**
* The application's route middleware groups.
*
* @var array
*/
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\App\Http\Middleware\SetAppConfigForUserMiddleware::class,
],
'api' => [
'throttle:60,1',
'bindings',
],
];
注意添加此选项会将中间件软件应用于 web.php内的所有路由
所以现在是测试部分
例如
My Auth:user()->name is John
My Auth:user()->email is john@email.com
在您的Project\Resources\views\home.blade.php
App Id Of User <code>{{config('app.APP_ID')}}</code>
App Secret Of User <code>{{config('app.APP_SECRET')}}</code>
所以我将APP_ID设置为
Config::set('app.APP_ID','appidOfUser'.Auth()->user()->name);
因此结果将是appidOfUser John
所以我将APP_SECRET设置为
Config::set('app.APP_ID','appsecretOfUser'.Auth()->user()->email);
因此结果将是appsecretOfUser john@email.com
因此 Auth :: user（）是动态的，基于用户，因此根据您在中间件中的要求设置
如果有任何问题，请在下面评论
答案 1 :(得分：0)
.env只能存储键值。
由于.env始终由config使用，因此您可以在运行时使用Config::set('app.id', 45678);来更改env。您可以将代码放在中间件中，请求结束后该值将恢复为默认值。
