I am using angular 2.4 version and router version "^3.4.10".
I am trying to handle redirect url using auth guard service.
When user hit url 'domain/assignment/3/detail' and if user is not login then user redirected to 'domain/login' page. and when user successfully login in to system then redirected to 'domain/assignment/3/detail' previous url which user tries to access.
I have implemented CanLoad guard on assignment module. so when user tries to access url 'domain/assignment/3/detail' and if user is not login, url stores into redirectUrl property of authservice (this.authService.redirectUrl).
so here is the issue comes in my case. i am not able to get full path of the url which user hit. i am getting 'assignment' instead 'assignment/3/detail' within CanLoad guard. how can i get full path so that i can redirect user to proper path within CanLoad guard.
CanLoad:
canLoad(route: Route): boolean {
let url = `/${route.path}`; // here i got url path 'assignment' instead 'assignment/3/detail'
return this.checkLogin(url);
}
Main routing app.routes.ts
const routes: Routes = [
{ path: '', redirectTo: 'login', pathMatch: 'full' },
{ path: 'login', component: LoginComponent},
{
path: 'assignment',
loadChildren: './assignment/assignment.module#AssignmentModule',
canLoad: [AuthGuard]
},
{ path: '**', redirectTo: '', pathMatch: 'full' }];
Assignment routing: assignment-routing.ts
const assignmentRoutes: Routes = [
{
path: '',
component: AssignmentComponent,
canActivate: [AuthGuard]
children: [
{
path: '',
canActivateChild: [AuthGuard],
children: [
{
path: ':assignmentId/detail', component: AssignmentDetailComponent,
canActivate: [AuthGuard]
}
]
}]
}];
AuthGuard: auth-gurad.service.ts
import { Injectable } from '@angular/core';
import {
CanActivate, Router,
ActivatedRouteSnapshot,
RouterStateSnapshot,
CanActivateChild,
NavigationExtras,
CanLoad, Route
} from '@angular/router';
import { AuthService } from './auth.service';
@Injectable()
export class AuthGuard implements CanActivate, CanActivateChild, CanLoad {
constructor(private authService: AuthService, private router: Router) { }
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
let url: string = state.url;
return this.checkLogin(url);
}
canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
return this.canActivate(route, state);
}
canLoad(route: Route): boolean {
let url = `/${route.path}`; // here i got url path 'assignment' instead 'assignment/3/detail'
return this.checkLogin(url);
}
checkLogin(url: string): boolean {
if (this.authService.isLoggedIn) {
if(this.authService.redirectUrl!=null){
let redirectUrl = this.authService.redirectUrl;
this.authService.redirectUrl = null;
this.this.router.navigate([redirectUrl]);
}
return true;
}
// Store the attempted URL for redirecting
this.authService.redirectUrl = url;
// Navigate to the login page
this.router.navigate(['/login']);
return false;
}
}
