如何在警卫服务中获取请求网址
HasPermissionService
@Injectable()
export class HasPermissionService implements CanActivate{
private permissions = [];
constructor(private _core:CoreService,private route1:Router,private _route:ActivatedRoute,private route: ActivatedRouteSnapshot,private state: RouterStateSnapshot) {
console.log('constructor calling ...');
// console.log(this.route.url);
this.permissions = this._core.getPermission();
console.log('inside guard');
console.log(this.permissions);
}
canActivate( ) {
console.log(this.route);
console.log(this._route);
return true;
}
}
但是我正在变老,我来自哪里.如何获取当前网址？
路线
{path:'grade-listing',component:GradeListingComponent,canActivate:[HasPermissionService]}
我需要获得’等级列表’
解决方法
在canActivate函数中,ActivatedRouteSnapshot和RouterStateSnapshot作为参数传递：
@Injectable()
export class HasPermissionService implements CanActivate {
private permissions = [];
constructor(private _core: CoreService) {
this.permissions = this._core.getPermission();
}
canActivate(
route: ActivatedRouteSnapshot,state: RouterStateSnapshot
): Observable<boolean>|Promise<boolean>|boolean {
//check here
}
}
您应该从那里开始查看正在激活的路线
