2. 添加proxy

2.1 前置条件

打开cmd.exe,输入ng --version查看是否安装了@angular/cli，如果没安装，可通过以下命令安装。

npm install -g @angular/cli

利用abp的命令自动生成proxy。此时有个前置条件是abp的命令只能调用dotnet tool下的API启动方式，无法调用基于IIS Express启动下的API。

即需要将Acme.BookStore.HttpApi.Host启动模式选择Acme.BookStore.HttpApi.Host

设置好后，点击F5启动程序。

2.2 利用abp自动生成angular端的service

vs code 打开angular目录，ctrl+`打开Terminal window, 然后输入一下命令敲回车。

3. 创建Books页面

此处UI组件用的是Ng Bootstrap， datatable组件用的是Ngx-Datatable.或者你可以使用PrimeNG - Angular UI Component Library

3.1 利用ng generate生成页面组件

此处利用ng命令去自动生成相关的ts文件。

ng generate module book --module app --routing --route books

以上代码创建book module和routing并指定route是books，并自动创建book相关的component，module和router，router会被自动添加到app-routing.module.ts中。

如果是你手动创建的component或者module，需要自己手动添加到app-routing.module.ts中。

loadChildren: () => import('./book/book.module').then(m => m.BookModule)这种方式是lazy-load的方式，只有在用户点击对应的页面的时候才会加载对应页面的js、css、html等。

3.2 在route.provider.ts中配置菜单

打开src/app/route.provider.ts，添加book-store 和books.

RoutesService是ABP用于配置主菜单和路径的，不是angualr原生。

path 访问此页面的URL

name 本地化菜单名字(localization document ).如果你不需要本地化，直接写死也可以的

iconClass 菜单图标 (你可以从Font Awesome 上面找到你需要的icons).

order 菜单的顺序.

layout BooksModule's routes布局方式 (提供了三种布局方式: eLayoutType.application, eLayoutType.account or eLayoutType.empty).

后面我会单独针对ABP的前端UI-Angular UI写一系列的文章ABP User Interface-Angular UI中文详解-CSDN博客。

import { RoutesService, eLayoutType } from '@abp/ng.core';
import { APP_INITIALIZER } from '@angular/core';

export const APP_ROUTE_PROVIDER = [
  { provide: APP_INITIALIZER, useFactory: configureRoutes, deps: [RoutesService], multi: true },
];

function configureRoutes(routesService: RoutesService) {
  return () => {
    routesService.add([
      {
        path: '/',
        name: '::Menu:Home',
        iconClass: 'fas fa-home',
        order: 1,
        layout: eLayoutType.application,
      },
      {
        path: '/book-store',
        name: '::Menu:BookStore',
        iconClass: 'fas fa-book',
        order: 2,
        layout: eLayoutType.application,
      },
      {
        path: '/books',
        name: '::Menu:Books',
        // iconClass: 'fas fa-user',
        parentName: '::Menu:BookStore',
        order: 3,
        layout: eLayoutType.application,
      }
    ]);
  };
}

3.2 添加页面内容到BookComponent

添加页面内容。

导入并注册BookService和ListService.

BookService是利用ng generate-proxy生成的服务

ListService是ABP团队创建的，提供了分页、排序和查询。ListService不是注册在root级别，他是component级别的，即component销毁后，当前页面的ListService会同步销毁。

具体可以在Working with Lists | ABP.IO Documentation中找到，后序我会在ABP User Interface-Angular UI中文详解-CSDN博客提供中文版本的使用说明。

3.2.1 book.component.ts

3.2.1.1 非standalone模式

import { Component, OnInit } from '@angular/core';
import { ListService, PagedResultDto } from '@abp/ng.core';  // Import ListService and PagedResultDto
import { BookService, BookDto } from '../proxy/books';  // Import your BookService and BookDto model
import { SharedModule } from '../shared/shared.module';

@Component({
  selector: 'app-book',
  templateUrl: './book.component.html',
  styleUrl: './book.component.scss',
  standalone: false, // 标记为独立组件
  // imports: [SharedModule], // 导入需要的模块
  providers: [ListService]  // Provide ListService for this component
})
export class BookComponent implements OnInit {
  book = { items: [], totalCount: 0 } as PagedResultDto<BookDto>;  // Initialize books as an empty PagedResultDto

  constructor(private bookService: BookService, public readonly list: ListService) { }  // Inject BookService and ListService

  ngOnInit() {  // Use ngOnInit to fetch books when the component initializes
    this.list.hookToQuery(this.bookService.getList).subscribe((response) => {  // Hook to the query and subscribe to the response
      this.book = response;  // Assign the response to books
    });
  }
}

还需要在book.module.ts声明BookComponent

import { NgModule } from '@angular/core';
// import { CommonModule } from '@angular/common';

import { SharedModule } from '../shared/shared.module';
import { BookRoutingModule } from './book-routing.module';
import { BookComponent } from './book.component';

@NgModule({
  declarations: [
    BookComponent
  ],
  imports: [
    BookRoutingModule,
    SharedModule// shared module already export CommonModule, so we don't need to import it again.
  ]
})
export class BookModule { }

3.2.1.2 standalone 模式 (推荐此模式)

如果使用的是Angualr 14+，则需要改成如下所示：

import { Component, OnInit } from '@angular/core';
import { ListService, PagedResultDto } from '@abp/ng.core';  // Import ListService and PagedResultDto
import { BookService, BookDto } from '../proxy/books';  // Import your BookService and BookDto model
import { SharedModule } from '../shared/shared.module';

@Component({
  selector: 'app-book',
  templateUrl: './book.component.html',
  styleUrl: './book.component.scss',
  standalone: true, // 标记为独立组件
  imports: [SharedModule], // standalone: true导入需要的模块
  providers: [ListService]  // Provide ListService for this component
})
export class BookComponent implements OnInit {
  book = { items: [], totalCount: 0 } as PagedResultDto<BookDto>;  // Initialize books as an empty PagedResultDto

  constructor(private bookService: BookService, public readonly list: ListService) { }  // Inject BookService and ListService

  ngOnInit() {  // Use ngOnInit to fetch books when the component initializes
    this.list.hookToQuery(this.bookService.getList).subscribe((response) => {  // Hook to the query and subscribe to the response
      this.book = response;  // Assign the response to books
    });
  }
}

book.module.ts移除BookComponent声明

import { NgModule } from '@angular/core';
import { SharedModule } from '../shared/shared.module';
import { BookRoutingModule } from './book-routing.module';

@NgModule({
  declarations: [
  ],
  imports: [
    BookRoutingModule,
    SharedModule// shared module already export CommonModule, so we don't need to import it again.
  ]
})
export class BookModule { }

3.2.2 book.component.html

Tips: 比如你想实现<div class="card"></div>，此时你只需要输入div.card然后直接敲Tab，vs code可以帮你自动生成。

类似的输入h5.card-title敲Tab自动生成<h5 class="card-title"></h5>

4.启动项目

后端API需要先启动。

npm start重新编译后，浏览器会自动打开，然后左侧会显示Book Store菜单。

展开后选择Books，加载数据完成如下图所示：

5. Angular推荐使用全独立模式避免NgModule的干扰

// AppComponent.ts（独立根组件）
import { Component } from '@angular/core';
import { BookComponent } from './book/book.component';
import { BrowserModule } from '@angular/platform-browser'; // 若需导入模块，需在 imports 中声明

@Component({
  selector: 'app-root',
  template: `<app-book></app-book>`,
  imports: [BrowserModule, BookComponent], // 导入依赖的模块和独立组件。类似把app.module.ts中的imports都放在此处
  standalone: true // 根组件标记为独立
})
export class AppComponent { }
