Angular2 routing authGuard service
Posted By : Avilash Choudhary | 30-Jun-2017
Hi Guys.
When you starting developing a application then you need to restrict some users to access some of the resources. Guest users have only access to particular resources and login user can have access to multiple modules. To achieve this we have implement the authguard service for routing. This authguard service will check the all access parameters and if user have access to that particular resource then it will return true otherwise false. In authguard serive,
suppose you have routing.ts file like this
const appRoutes: Routes = [
{
path: '',
redirectTo: 'login',
pathMatch: 'full'
},
{
path: 'login',
component: LoginComponent
},
{
path: 'adminWeb',
component: SidebarComponent,
children: [
{
path: '',
redirectTo: 'addEnterprise',
pathMatch: 'full'
},
{
path: 'manageMsisdn',
component: ManageMsisdnComponent,
canActivate: [AuthGaurdService],
data: { "type": "whitelist" }
},
{
path: 'configureCloud',
component: ConfigureCloudComponent,
canActivate: [AuthGaurdService],
data: { "type": "cloud" }
},
{
path: 'cloudManage',
component: CloudManageComponent,
canActivate: [AuthGaurdService],
data: { "type": "cloud" }
},
{
path: 'slaManage',
component: SlaManageComponent,
canActivate: [AuthGaurdService],
data: { "type": "sla" }
},
]
}
];
export const routing = RouterModule.forRoot(appRoutes);
In your routing file, you have provide the Authguard Service to canActivate property, So whenever that route is checked, first of all it will look to authguard service, if he gets true then only redirect to that route, otherwise nothing will happen.
your service file will look like this:
@Injectable() export class AuthGaurdService implements CanActivate, Resolve{ constructor(private baseUtils: BaseUtils, private router: Router) { } canActivate(route: ActivatedRouteSnapshot): boolean { let data: any = route.data; if (data && data.type) { if (data.type == "whitelist") { return true; } else { this.router.navigate(["adminWeb/addEnterprise"]); // if user don't have access to whitelist module then redirect to other page return false; } } else { return true; } } }
