Connection with identity provider

Change the parameters of the variable mgr of the script SecurityService.js to the values of your identity provider.

var mgr = new Oidc.UserManager({
  userStore: new Oidc.WebStorageStateStore(),  
  authority: 'https://localhost:44321',
  client_id: 'vuejsclient',
  redirect_uri: window.location.origin + '/static/callback.html',
  response_type: 'id_token token',
  scope: 'openid profile address roles identityserver4api country subscriptionlevel offline_access',
  post_logout_redirect_uri: window.location.origin + '/index.html',
  silent_redirect_uri: window.location.origin + '/static/silent-renew.html',
  accessTokenExpiringNotificationTime: 10,
  automaticSilentRenew: true,
  filterProtocolClaims: true,
  loadUserInfo: true
})

The script SecurityService.js contains triggers and methods from the oidc-client library.

API

The script ApiService.js is responsible for making requests to an API using the libraries oidc-client and axios

The baseUrl constant receives the static part of the API Url.

const baseUrl = 'https://localhost:44390/api/';

The defineHeaderAxios() method appends the access teken to the axios head.

async defineHeaderAxios () {
    await user.getAcessToken().then(
      acessToken => {
        axios.defaults.headers.common['Authorization'] = 'Bearer ' + acessToken
      }, err => {
        console.log(err)
      })  
  }

The getAll() method makes a get request. It receives as a parameter a string that will be concatenated with the baseUrl constant by forming the API Url.

async getAll(api){
    await this.defineHeaderAxios() 
    return axios
      .get(baseUrl + api)
      .then(response => response.data)
      .catch(err => {
        console.log(err);
      })
  }

Route protection

The script index.js is responsible for managing the application routes using the vue router. Each route has a field called meta. Meta receives two parameters: requiresAuth and role.

requiresAuth[Bollean]: Responsible for protecting the route
role[String]: Users with this role will be allowed to access the route

{
  path: '/payinguser',
  name: 'PayingUser',
  component: PayingUser,
  meta: {
	requiresAuth: true,
	role: ['PayingUser']
  }
},
{
  path: '/freeuser',
  name: 'FreeUser',
  component: FreeUser,
  meta: {
	requiresAuth: true,
	role: ['FreeUser']
  }
}

At each transition of routes in the application, the router.beforeEach() method of the script index.js is called. This method checks whether the user who is logged in is allowed to access the route. It does this by comparing the role of the user and the role of the route.

router.beforeEach((to, from, next) => {
  const requiresAuth = to.matched.some(record => record.meta.requiresAuth);
  if (requiresAuth) {
      mgr.getRole().then(
        sucess => {
          if (to.meta.role == sucess){
            next();
          }else {
            next('/accessdenied');
          }
        },
        err => {
          console.log(err);
        }
      );    
  } else {
    next();
  }
});
