laravel框架自带session

session是php中的一个重要的特性

我们可以用session会话来跟踪用户

除了在app/Http/Kernel.php中开启session

还可以在路由中开启

以下是方法

<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

Route::group(['middleware' => ['\Illuminate\Session\Middleware\StartSession']], function ($router) {
    Route::get('/session', 'SessionController@index');
    Route::get('/getsession', 'getSessionController@index');
});

以下是设置session的controller

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Session;
class SessionController extends Controller
{
    public function index(Request $request){
        $request->session()->put('key','value');//设置session
        session(['key1' => 'value1']);
        Session::flash('milkcaptcha', 'test');
    }
}

以下是获取session的controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Session;
class getSessionController extends Controller
{
    //
    public function index(Request $request){
        $key = $request->session()->get('key');//获取session的值
        echo "key->".$key."<br>";
        echo 'key1->'.session('key1');
        echo "key".Session::get('milkcaptcha');
    }
}
