Lumen框架 之加入session

一、修改Lumen

1、打开bootstrap/app.php，在相应位置添加注册SessionServiceProvider

$app->register(Illuminate\Session\SessionServiceProvider::class);

2、同样在bootstrap/app.php中添加配置代码

$app->configure('session');

3、打开bootstrap/app.php，在Register Middleware位置修改

 $app->middleware([
//     App\Http\Middleware\ExampleMiddleware::class,
     Illuminate\Session\Middleware\StartSession::class
 ]);

4、修改别名，因为框架中使用了session别名，所以需要添加alias，不然会报错

$app->alias('session', 'Illuminate\Session\SessionManager');

5、在项目根目录创建config文件夹，并新建session.php配置文件

return [
    'driver' => env('SESSION_DRIVER', 'file'),//默认使用file驱动，你可以在.env中配置
    'lifetime' => 120,//缓存失效时间
    'expire_on_close' => false,
    'encrypt' => false,
    'files' => storage_path('framework/session'),//file缓存保存路径
    'connection' => null,
    'table' => 'sessions',
    'lottery' => [2, 100],
    'cookie' => 'laravel_session',
    'path' => '/',
    'domain' => null,
    'secure' => false,
];

二、简单使用

1、web.php路由文件

<?php

/** @var \Laravel\Lumen\Routing\Router $router */

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It is a breeze. Simply tell Lumen the URIs it should respond to
| and give it the Closure to call when that URI is requested.
|
*/


$router->group(['middleware' => 'test'], function () use ($router) {
    $router->get('/', function () use ($router) {
        return $router->app->version() .' - '. app('session')->get('username', '');
    });
});

$router->get('/test', ['uses' => 'ExampleController@show']);

$router->get('/login', ['uses' => 'ExampleController@login']);

$router->get('/logout', ['uses' => 'ExampleController@logout']);

2、ExampleController

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\DB;

class ExampleController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {

    }

    //
    
    public function show()
    {
        $admin = DB::table('blog_admin')->forPage(1,10)->get()->toArray();
        //var_dump($admin);
        
        $username = app('session')->get('username', '');
        //var_dump($username);

        //echo response()->json($admin);
        
        return view('test.test', ['name' => $username]);
    }
    
    public function login()
    {
        $res = app('session')->put('username', 'yy123');
        
        //var_dump(app('session'));exit;
        return redirect('/');
    }

    public function logout()
    {
        app('session')->put('username', '');
        return redirect('/test');
    }
}

3、ExampleMiddleware.php

<?php

namespace App\Http\Middleware;

use Closure;

class ExampleMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $username = app('session')->get('username');
        if(!$username) {
            return redirect('/test');
        }
        return $next($request);
    }
}

4、app.php

 $app->routeMiddleware([
     //'auth' => App\Http\Middleware\Authenticate::class,
     'test' => App\Http\Middleware\ExampleMiddleware::class
 ]);
