上一节解决了用户注册和登录数据部分的内容。这一节开始分析用户模块、用户路由。## 用户管理模块UserModule分析 ##
UserModule主要代码如下:
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { LoginComponent } from './login/login.component';
import { UsersComponent } from './users/users.component';
import { UsersRoutingModule } from './users-routing.module';
import { HomeComponent } from './home/home.component';
import { RegistComponent } from './regist/regist.component';
@NgModule({
imports: [
CommonModule,
FormsModule,
ReactiveFormsModule,
UsersRoutingModule,
],
declarations: [
UsersComponent,
LoginComponent,
HomeComponent,
RegistComponent,]
})
export class UsersModule { }
import数组中,CommonModule:是构建子组件必须引入的模块。用户登录控件(LoginComponent)使用了模板驱动表单,需要导入FormsModule,用户注册组件(RegistComponent)使用了响应式表单,需要导入ReactiveFormsModule,用户路由模块UsersRoutingModule主要代码如下:
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { UsersComponent } from './users/users.component';
import { HomeComponent } from './home/home.component';
import { RegistComponent } from './regist/regist.component';
const usersRoutes: Routes = [
{
path:'',
component:UsersComponent,
children:[
{path:'', component:HomeComponent},
{path: 'login', component: LoginComponent},
{path:'regist',component:RegistComponent}
]
},
];
@NgModule({
imports:[
RouterModule.forChild(usersRoutes)
],
exports:[
RouterModule
]
})
export class UsersRoutingModule{}
当进入主页(localhost)时,因为AppRoutingModule中直接重定向到users,所以直接进入到了users的路由,进入users路由后,直接加载了users模块的UsersRoutingModule,当路由为''时,加载UsersComponent组件,UsersComponent组件只有一个路由插座标签:
<router-outlet></router-outlet>
所有users模块的组件都要在这对标签中呈现。他的子路由包括
{path:'', component:HomeComponent},
{path: 'login', component: LoginComponent},
{path:'regist',component:RegistComponent}
所以,最终的初始页面为HomeComponent组件的模板内容:
<p class="lead">
<a class="btn btn-primary btn-lg" name="login" triggers="manual" #login="ngbPopover" placement="left" (mouseenter)="showPopver($event)"
(mouseleave)="closePopover($event)" [routerLink]="['login']" ngbPopover="Please login first" role="Login">Login</a>
<a class="btn btn-warning btn-lg" #regist="ngbPopover" placement="right" (mouseenter)="showPopver($event)" (mouseleave)="closePopover($event)"
[routerLink]="['regist']" name="regist" data-toggle="tooltip" ngbPopover="Please regist a user" role="regist">Regist</a>
</p>
在这个模板中的两个链接标签中,分别提供了导航到登录和注册路由的routerLink:
- [routerLink]="['login']
- [routerLink]="['regist']"
当点击Login标签时,根据路由定义直接跳转到LoginComponent组件,进行用户的登录操作。
当点击Regist标签时,根据路由定义直接跳转到RegistComponent组件,进行用户的注册操作。

来通知其他用户。
