我有一个登录页面,我正在使用防护功能。因此,一旦用户输入正确的数据(用户名和密码),他将被重定向到个人资料页面/profile/profile.component.ts
。
现在我想为受保护的页面/组件/profile/profile.component.ts
使用额外的模块,并在登录成功时从路由器模块重定向到它。因此,我首先生成了一个名为dashboard.module.ts
的新/第二个模块,其中我有一个应用程序组件app.component
。结构如下:
/src
/app
app.module.ts
app.component.ts
router.ts
/dashboard
/app
app.component.ts
dashboard.module.ts
dashborad.component.ts:
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { AppComponent } from 'app/dashboard/app/app.component';
@NgModule({
imports: [
CommonModule
],
exports: [
AppComponent
],
declarations: [AppComponent]
})
export class DashboardModule { }
/ dashboard下的app.component.ts:
import { Component, OnInit, NgModule } from '@angular/core';
@Component({
selector: 'app-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
@NgModule({
exports:[]
})
export class AppComponent implements OnInit {
constructor() { }
ngOnInit() {}
}
我可以使用ng serve
启动应用程序而不会出现任何错误,但是当我运行AOT(Ahead-of-Time Compilation)时,我会收到以下错误:
ERROR in Illegal state: Could not load the summary for directive AppComponent in /Users/user/Dev/dashboard-app/src/app/dashboard/app/app.component.ts.
当我在app.component.ts中添加导出AppComponent
时:
...
@NgModule({
exports:[AppComponent]
})
...
我遇到这个错误:
ERROR in Maximum call stack size exceeded
ERROR in ./src/main.ts
Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in '/Users/user/Dev/dashboard-app/src'
@ ./src/main.ts 3:0-74
@ multi ./src/main.ts
有什么想法解决这个问题吗?或者我是否构建了错误的结构和/或错误的概念?
答案 0 :(得分:0)
问题解决了。我确实更改了Not-Public组件的结构...现在,dashboard文件夹包含一个模块:dashboard.module.ts
以及用户登录后可以访问的其他子文件夹。我也改变并修复了dashboard.module.ts
结构:
src/
app/
dashboard/
dashboard.component.ts
dashboard.component.html
dashboard.component.css
dashboard.module.ts
profile/
profile.component.ts
profile.component.html
profile.component.css
add/
add.component.ts
add.component.html
add.component.css
....
signup/
howto/
main.ts
dashboard.module.ts:
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { CommonModule } from '@angular/common';
import { ProfileComponent } from './profile/profile.component';
import { AddComponent } from './add/add.component';

} from '@angular/material';
const dashBoardRoutes: Routes = [
{ path:'', redirectTo: 'dashboard', pathMatch:'full' },
{ path:'dashboard', component: DashboardComponent,
children: [
{ path:'add', component: AddComponent},
{ path:'profile', component: ProfileComponent},
]},
];
@NgModule({

ProfileComponent, DashboardComponent, AddComponent
],
imports: [ FormsModule, ReactiveFormsModule,
MdDatepickerModule, MdInputModule,
RouterModule.forChild( dashBoardRoutes )
],
providers:[],

exports:[ProfileComponent, AddComponent],
bootstrap: [

export class DashboardModule { }
