我想从空路径“”重定向到我的登录页面,当用户没有进入时。所以我使用警卫和儿童路线来做到这一点。但是,我的代码适用于除“”之外的所有路由。
这是我的守卫(canValidate功能)
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):boolean {
return this.canMethod();
}
canMethod () {
if (Environment.ActivateGuard) {
let token = this._auth.getCookie(AuthorizationEnum.cookieName);
if(token) { // token exists
let data = {
token: token,
module: this.module
};
this._auth.validate(data, AuthorizationEnum.Bearer).subscribe(
data => { // valid token
if ( data.res == AuthorizationEnum.emptyResponse) { // invalid user, it doesn't belongs to this module.
this.letsRedirect();
}
else {
let user_role = data.det[1]; // this is the user's role!.
}
},
error => { // other error
this.letsRedirect();
}
);
return true;
}
else { // user don't have token
this.letsRedirect();
}
}
else {
return true;
}
}
letsRedirect(){
window.location.href = Environment.authAppUrl + AuthorizationEnum.redirectQuery + encodeURIComponent(this.url);
}
这是我的app-routing.module.ts(只有路由数组)
const routes: Routes = [
// TODO: Validar esta ruta
//{ path: '', component: LoginComponent, pathMatch: 'full' },
//Con header
{
path: '',
children: [
{ path: '', component: HomeComponent,canActivate:[AuthorizatedGuard]},
{ path: 'inicio', component: HomeComponent, canActivate:[AuthorizatedGuard] },
{ path: 'categorias', redirectTo: 'base-lista/categorias'},
{ path: 'videos', redirectTo: 'base-lista/videos'},
{ path: 'base-lista/:idList', component: BaseListComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/categorias/gestionar-categorias', component: CategoryVideoComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/categorias/ver-detalles-categoria', component: ViewDetailsCategoryComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/videos/gestionar-videos', component: VideoComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/videos/ver-detalles-video', component: ViewDetailsVideoComponent, canActivate:[AuthorizatedGuard] },
],
component: AppLayoutComponent,
canActivate: [AuthorizatedGuard],
},
//sin header
{
path: '',
component: LoginComponent,
children: [
{
path: 'login',
component: LoginComponent
}
]
}
];
当我们尝试访问“htpp:// localhost:4200 /”时,Angular将评估路径路径。配置的第一条路径的路径的第一部分是“”,所以让我们继续评估第二部分也是“”,所以我们匹配!但是警卫仍然需要验证用户是否可以访问HomeLayoutComponent(如果用户已登录)。如果用户已登录,则授予访问权限,用户将看到HomeLayoutComponent(导航栏以及HomeComponent在路由器插座中呈现),否则将重定向到“htpp:// localhost:4200 / login ”。
所以假设我们正在尝试访问“htpp:// localhost:4200 / login”。 Angular将再次评估路径路径。配置的第一个路径的路径的第一部分是“”,所以让我们继续评估第二部分是“登录”,所以我们没有匹配。我们需要评估配置的下一个路由。我们再来吧!配置的第一个路径的路径的第一部分是“”(这次),所以让我们继续评估第二部分是“登录”并且我们有一个匹配。在这种情况下,将显示LoginLayoutComponent。由于HTML模板中只有一个路由器插座,因此只显示LoginComponent。
I am using this link to create the routing
那么..我的代码出了什么问题?
你试过从你的''
删除LoginComponent
路径吗?这似乎是多余的。除非您使用单独的布局,否则您需要指定您正在使用的布局组件(如AppLayoutCompnent
)而不是LoginComponent
两次。
更改
{
path: '',
component: LoginComponent,
children: [
{
path: 'login',
component: LoginComponent
}
]
}
只是
{
path: 'login',
component: LoginComponent
}
要么
{
path: '',
component: LoginLayoutComponent, // <---
children: [
{
path: 'login',
component: LoginComponent
}
]
}
您应该看到的另一件事是使用路由器来处理重定向而不是window.location
。这是处理它的“Angular”方式。将Router
注入你的守卫并用它来导航。
letsRedirect(){
this.router.navigate(['/login'], { queryParams: { redirectUrl: this.url } });
}
最后,您可以使用CanActivateChild
简化路线。它将对所有子路径执行检查,而不是为每个子路径添加防护。
{
path: '',
children: [
{ path: '', component: HomeComponent,
{ path: 'inicio', component: HomeComponent },
{ path: 'categorias', redirectTo: 'base-lista/categorias'},
{ path: 'videos', redirectTo: 'base-lista/videos'},
{ path: 'base-lista/:idList', component: BaseListComponent },
{ path: 'base-lista/categorias/gestionar-categorias', component: CategoryVideoComponent },
{ path: 'base-lista/categorias/ver-detalles-categoria', component: ViewDetailsCategoryComponent },
{ path: 'base-lista/videos/gestionar-videos', component: VideoComponent },
{ path: 'base-lista/videos/ver-detalles-video', component: ViewDetailsVideoComponent },
],
component: AppLayoutComponent,
canActivateChild: [AuthorizatedGuard],
},
并更新你的警卫
canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot):boolean
我设法解决了我的问题,包括没有警卫重定向到登录页面的空路线,所以如果该人没有登录他将重定向他登录否则,他将输入以下定义,始终确保该人已经登录系统。
const routes: Routes = [
// Sin header
{ path: '', component: LoginComponent, pathMatch: 'full' },
//Con header
{
path: '',
children: [
{ path: '', component: HomeComponent,canActivate:[AuthorizatedGuard]},
{ path: 'inicio', component: HomeComponent, canActivate:[AuthorizatedGuard] },
{ path: 'categorias', redirectTo: 'base-lista/categorias'},
{ path: 'videos', redirectTo: 'base-lista/videos'},
{ path: 'base-lista/:idList', component: BaseListComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/categorias/gestionar-categorias', component: CategoryVideoComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/categorias/ver-detalles-categoria', component: ViewDetailsCategoryComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/videos/gestionar-videos', component: VideoComponent, canActivate:[AuthorizatedGuard] },
{ path: 'base-lista/videos/ver-detalles-video', component: ViewDetailsVideoComponent, canActivate:[AuthorizatedGuard] },
],
component: AppLayoutComponent,
canActivate: [AuthorizatedGuard],
},
];
ps:对不起我的英语
这对我有用
[
{
path: '',
pathMatch: 'full',
redirectTo: 'teams'
},
{
path: 'teams',
component: TeamsComponent
}
]
