Message:

I am using laravel 8 with sanctum api (vue 3 spa).

I have never used localization before....and for this app I need that.

I created a middleware SetLocale with this content

public function handle($request, Closure $next)

    {

        app()->setLocale(config('app.locale'));

        if(session()->has('locale')) {

            app()->setLocale(session('locale'));

        }

 

        return $next($request);

    }

and registered in both web and api (app/Http/Kernel.php) @middlewareGroups

From the login form there is a select that change locale and make a post request to server to change the locale

Session()->put('locale', $request->input('locale'));

app()->setLocale(session('locale'));



return response()->json(['locale' => app()->currentLocale()]);

In the login form the server validation responds with the locale messages.... but the problem is the customized message (Customize laravel sanctum unauthorize response) it is not translated - it gives me in 'en' ... even if the locale is 'de'

$this->renderable(function (\Illuminate\Auth\AuthenticationException $e, $request) {

    if ($request->is('api/*')) {

        return response()->json([

            'message' => trans('_custom.not_authenticated')

        ], 401);

    }

});

The file is there for every language _custom.php (resources/lang/de, resources/lang/en, etc )

example for _custom.php "de":

<?php



return [

   'not_authenticated' => 'Nicht berechtigt'

];

The message is still in en ... but if press login (without changing anything) .... the validation errors are in 'de'

Why ? What I missed ?

Could be that the message is returned before the middleware runs ?

*** UPDATE 1 ***

It seems to work partially using in request Accept Language header .... but there is another problem.

In vue I have this approach for the axios:

const api = axios.create({

  withCredentials: true,

  headers: {

    common: {

      'Accept-Language': document.documentElement.lang

    }

  }

});



export default api;

In the vue app when changing the language .... I also update the document.documentElement.lang value ... but when making a request it still the default value 'en'

Is there any way I can change dynamic the value for the 'Accept-Language' header instead of adding for each request the header ?

My Answer:

Then, in your controller or wherever you are returning the JSON response, you can use the `trans()` function to translate the message. For example:

php
return response()->json([
'message' => trans('messages.success'),
]);


Make sure you have the translation file set up in your `resources/lang` directory with the appropriate translations.
