Laravel:如何在AppServiceProvider中访问会话值? [英] Laravel: How to access session value in AppServiceProvider?

问题描述

有什么方法可以访问AppServiceProvider中的Session值?我想在所有视图中全局共享会话价值.

Is there any way available to access Session values in AppServiceProvider? I would like to share session value globally in all views.

推荐答案

您不能直接从服务提供商读取会话:在Laravel中，该会话由StartSession中间件处理，该中间件在所有服务提供商启动阶段之后执行

You can't read session directly from a service provider: in Laravel the session is handled by StartSession middleware that executes after all the service providers boot phase

如果您想与所有视图共享会话变量，则可以使用视图编辑器来自您的服务提供商:

If you want to share a session variable with all view, you can use a view composer from your service provider:

public function boot()
{
    view()->composer('*', function ($view) 
    {
        $view->with('your_var', \Session::get('var') );    
    });  
}

作为第二个参数传递给作曲家的回调将在呈现视图时被调用，因此StartSession届时将已经执行

The callback passed as the second argument to the composer will be called when the view will be rendered, so the StartSession will be already executed at that point
