在实现 Laravel 自带语言包自动切换功能时中文语言包不识别？

切换语言包按钮时 进行设置语言

 public function set_lang(Request $request){
        $lang = $request->lang;
        \App::setLocale($lang);
        $res = $request->session()->put('language',$lang);  
        $seccess = array(
            'code'=>200,
            'data'=> \App::getLocale('language')
        );
        return response()->json($seccess); 
    }

   <h2 class="listTitle">——   {{ trans('ohi.latest_ohi_inter') }}    ——</h2>

语言包都是存在的字段也存在

结果:

我的config/app中的设置

 'locale' => 'en',

    /*
    |--------------------------------------------------------------------------
    | Application Fallback Locale
    |--------------------------------------------------------------------------
    |
    | The fallback locale determines the locale to use when the current one
    | is not available. You may change the value to correspond to any of
    | the language folders that are provided through your application.
    |
    */

    'fallback_locale' => 'zh_CN',
