Laravel 5.0 Session can't use static methods
提问by user13746
I'm trying to create app with Laravel 5.0 and I have problem with using Session methods in my BaseController constructor
我正在尝试使用 Laravel 5.0 创建应用程序，但在BaseController 构造函数中使用 Session 方法时遇到问题
Here is my BaseController with it's consturctor.
这是我的 BaseController 及其构造函数。
use Symfony\Component\HttpFoundation\Session\Session;
class BaseController extends Controller {
/**
* Initializer.
*
* @access public
* @return \BaseController
*/
public function __construct()
{
//set default lang
if (!Session::has('lang')) {
Session::put('lang', App::getLocale());
Cookie::forever('lang', App::getLocale());
} else {
App::setLocale(Session::get('lang'));
}
}
}
but I get this error
但我收到这个错误
ContextErrorException in BaseController.php line 22: Runtime Notice: Non-static method Symfony\Component\HttpFoundation\Session\Session::has() should not be called statically, assuming $this from incompatible context
BaseController.php 第 22 行中的 ContextErrorException：运行时注意：非静态方法 Symfony\Component\HttpFoundation\Session\Session::has() 不应静态调用，假设 $this 来自不兼容的上下文
Does anyone know what I'm doing wrong?
有谁知道我做错了什么？

Instead of:
代替：
use Symfony\Component\HttpFoundation\Session\Session;
you should use:
你应该使用：
use Session;
to import Session here.
在这里导入会话。

You're importing the wrong class. Symfony\Component\HttpFoundation\Session\Sessionis the class used by Laravel when you call the Session::facade - but they're not the same class, and Symfony's session class doesn't use a static method for has(). I haven't used Laravel 5 myself, but I think it's in the top-level namespace.
你导入了错误的类。Symfony\Component\HttpFoundation\Session\Session是 Laravel 在您调用Session::外观时使用的类- 但它们不是同一个类，并且 Symfony 的会话类不使用静态方法has(). 我自己没有使用过 Laravel 5，但我认为它在顶级命名空间中。
