Laravel5.5 动态切换多语言的操作方式

return [
 "test" => "这里是测试",
 "test1" => "继续测试",
 ......
];

return [
 "test" => "this is a test...",
 "test1" => "test again...",
 ......
];

'locale' => 'zh',
'locales' => ['zh','en','cht'], //包含的语言种类
'fallback_locale' => 'cht',

<?php
namespace App\Http\Controllers\Home;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\App;
use Session;
class LangController extends Controller{
 /**
  * 切换语言包
  * @param Request $request
  */
 public function language(Request $request){
  if($request->ajax()) { //Ajax请求访问
   $lang = $request->all();
   $lang = $lang['lang'];
   App::setLocale($lang); //配置默认语言
   $request->session()->put('language',$lang); //存到session
   return App::getLocale();
  }else{
   if($request->session()->has('language')){
    $res = $request->session()->get('language'); //获取session
    return $res;
   }
 
  }
