Laravel 5.7在刀片中回显会话值

Question

I am trying to echo out the value of a session that I set in Controller

public function changeLanguage(Request $request){
    if($request->ajax()){
        $request->session()->put('locale',$request->locale);
        $request->session()->flash('alert-success',('app.Locale_Change_Success'));
    } 
}

the Values of $request->local that submits by ajax are and . Now I want to the value of and in blade, the code looks like this

@if(Session::has('locale','en'))
    <link rel="stylesheet" type="text/css" href="css/en.css">
@endif
@if(Session::has('locale','dr'))
    <link rel="stylesheet" type="text/css" href="css/dr.css">
@endif

According to the Laravel docs one way to check it could be this:

@if(session()->has('locale'))
    <link rel="stylesheet" type="text/css" href="css/{{ session()->get('locale') }}.css">
@endif

This saves you duplicate code (the <link> tag) and is easier to read. It also saves you the hassle of checking for each possible locale you might add in the future.
