I have used Auth library for my Vue/Nuxt project. JWT Authentication works for me just fine, but there is a problem with refresh token.

First of all refreshToken cookie is always set to null:

enter image description here

Secondly, when i call this.$auth.refreshTokens() i got an error:

this.$auth.refreshTokens is not a function

I have been trying for a long time to solve this, but i finally give up :(

You can see my server side and client side code on my GitHub.

For a shortcat, below is fragment of nuxt.config.js file:

   auth: {
    strategies: {
      local: {
        scheme: 'refresh',
        token: {
          property: 'token',
          maxAge: 30,
          // type: 'Bearer'
        },
        refreshToken: {
          property: 'refreshToken',
          data: 'refreshToken',
          maxAge: 60
        },
        user: {},
        endpoints: {
          login: { url: 'users/login', method: 'post' },
          refresh: { url: 'users/refreshToken', method: 'post' },
          user: { url: 'users/me', method: 'get', propertyName: '' },
          logout: false
        },
        // autoLogout: false
      }
    }
 },

I have already checked if all names in the client config file and server are meet. Thank you in advance for your help and i am so sorry for mistakes in my English, i did my best...

I think I made it, let me share with you what i did I worte a plugin called auth this plugin basicly co the following

  • check if there is a token stored or not
  • then check if the stored token has been expiried or not by making a request to get the user data
  • if the request fails we make a request to /refresh endpoint which refresh the current token in the request headers then send it back in the response
  • we take this new token and store at in the client side
  • if the refresh request fails too, we cleared the auth object

This is the plugin code

const strategy = 'local'
const FALLBACK_INTERVAL = 900 * 1000 * 0.75

async function refreshTokenF($auth, $axios, refreshToken) {
    try {
        const response = await $axios.post('/refresh')
        let token = 'Bearer ' + response.data.token
        console.log(refreshToken);
        console.log(token);
        $auth.setToken(strategy, token)
        $axios.setToken(token)
        return decodeToken.call(this, token).exp
    } catch (error) {
        $auth.logout()
        throw new Error('Error while refreshing token')
    }
}

export default async function ({app}) {

    const {$axios, $auth} = app

    let token = $auth.getToken(strategy)
    let refreshInterval = FALLBACK_INTERVAL
    if (token) {
        $axios.get('/me').then((resp) => {
            $auth.setUser(resp.data.data)
        }).catch(async () => {
            try {
                await refreshTokenF($auth,$axios,token);
            } catch (e) {
                $auth.logOut();
            }
        })
    }

    setInterval(async function () {
        token = $auth.getToken(strategy)
        await refreshTokenF($auth, $axios, token)
    }, refreshInterval)

}

Also have a look on my controller to refresh the token

<?php


namespace App\Http\Controllers\Api\Auth;


use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Mpdf\Tag\THead;
use Tymon\JWTAuth\JWTAuth;

class RefreshController extends Controller
{

    protected $auth;
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct(JWTAuth $auth)
    {
        $this->auth = $auth;
    }

    public function refresh(Request  $request)
    {
        $this->auth->setRequest($request);
        $arr = $this->auth->getToken();
        $arr = $this->auth->refresh();
        $this->auth->setToken($arr);
        return response()->json([
            'success' => true,
            'data' => $request->user(),
            'token' => $arr
        ], 200);    }

}

Here is what I did to make it work:

npm install --save @nuxtjs/auth-next

nuxt.config.js

    strategies: {
        refresh: {
            scheme: 'refresh',
            token: {
                property: 'access_token',
                maxAge: 1800,
                global: true,
            },
            refreshToken: {
                property: 'refresh_token',
                data: 'refresh_token',
                maxAge: 60 * 60 * 24 * 30,
            },
            user: {
                property: false,
            },
            endpoints: {
                login: {
                    url: `${process.env.OAUTH_URL}/oauth/token`,
                    method: "post",
                    propertyName: false
                },
                user: {
                    url: `${process.env.OAUTH_URL}/api/user`,
                    method: 'get',
                },
                logout: false,
            }
        },
    }

The user property: false flag is important because my user payload has all the user fields directly in the response:

{
    id: '',
    email: '',
    name: '',
    role: '',
}

login.vue

            await this.$auth.loginWith("refresh", {
                data: {
                    grant_type: "password",
                    client_id: process.env.CLIENT_OAUTH_ID,
                    client_secret: process.env.CLIENT_OAUTH_KEY,
                    scope: "*",
                    username: this.credentials.email,
                    password: this.credentials.password
                }
            });
