Laravel操作session和cookie的教程详解

'driver' => env('SESSION_DRIVER', 'file'),//#这里表示先读取.env文件的SESSION_DRIVER参数值,如果没有使用file驱动

'lifetime' => env('SESSION_LIFETIME', 120),

'files' => storage_path('framework/sessions'),

'connection' => null,//不修改使用默认的redis

'table' => 'sessions',

/**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('sessions', function (Blueprint $table) {
            $table->string('id')->unique();
            $table->unsignedBigInteger('user_id')->nullable();
            $table->string('ip_address', 45)->nullable();
            $table->text('user_agent')->nullable();
            $table->text('payload');
            $table->integer('last_activity');
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('sessions');
    }

$request->session()->put('key', 'value');//设置session
$request->session()->push('arr','item');//session数组数据中追加数据

session(['key' => 'value']);//设置session
session()->push('arr','item');//session数组数据中追加数据

$data = $request->session()->all();//获取所有session
$value = $request->session()->get('key');//获取指定session

$value = $request->session()->get('key', 'default');
$value = $request->session()->get('key', function () {
    return 'default';
});
//确定 Session 中是否存在某个值,该值存在且不为 null，那么 has 方法会返回 true
if ($request->session()->has('key')) {
    //
}
//确定 Session 中是否存在某个值,即使其值为 null,返回 true
if ($request->session()->exists('key')) {
    //
}

$value = session('key');
$value = session('key', 'default');
$value = session()->get('key')
$value = session()->get('key','default')
session()->has('key');
session()->exists('key');

//获取到session数据然后删除session
$value = $request->session()->pull('key', 'default');
//删除指定session
$request->session()->forget('key');
//删除所有session
$request->session()->flush();

//删除指定session
session()->forget('name');
//清空所有session
session()->flush();

$request->session()->regenerate();

session()->regenerate();

Cookie::queue('test', 'testValue', 10);//设置cookie,test值为testValue,设置cookie时长10分钟
Cookie::make('cookie_name', 'value', 10);//设置cookie,cookie_name值为value,设置cookie时长10分钟
Cookie::forever('key','value');//设置cookie，key值为value，永不过期

return \response()->view('index',$data)->withCookie($cookie);

Cookie::get('key');

Cookie::forget('key');
