Abp vNext学习(3) 创建书籍信息展示页

　　前面已经完成书籍信息后台的业务，现在来展示书籍信息

　　首先准备本地化文本(Localization Text,不知道是不是这么翻译，暂时这么叫)

　　找到.Domain.Shared类库下面的Localization/BookStore/en.json

　　修改如下：

{
  "Culture": "en",
  "Texts": {
    "Menu:Home": "Home",
    "Welcome": "Welcome",
    "LongWelcomeMessage": "Welcome to the application. This is a startup project based on the ABP framework. For more information, visit abp.io.",
    "Menu:BookStore": "Book Store",
    "Menu:Books": "Books",
    "Actions": "Actions",
    "Close": "Close",
    "Delete": "Delete",
    "Edit": "Edit",
    "PublishDate": "Publish date",
    "NewBook": "New book",
    "Name": "Name",
    "Type": "Type",
    "Price": "Price",
    "CreationTime": "Creation time",
    "AreYouSure": "Are you sure?",
    "AreYouSureToDelete": "Are you sure you want to delete this item?",
    "Enum:BookType:0": "Undefined",
    "Enum:BookType:1": "Adventure",
    "Enum:BookType:2": "Biography",
    "Enum:BookType:3": "Dystopia",
    "Enum:BookType:4": "Fantastic",
    "Enum:BookType:5": "Horror",
    "Enum:BookType:6": "Science",
    "Enum:BookType:7": "Science fiction",
    "Enum:BookType:8": "Poetry"
  }
}

　　这是一些基础配置，可以随便写，但是规范：

　　1.菜单前加Menu:，比如Menu:Home

　　2.使用类似Enum:<type>:<value>定义枚举类型

　　首先确保安装了npm和angular脚手架

　　cmd安装yarn:npm install yarn -g

　　安装angular脚手架：npm install -g @angular/cli

　　可能遇到node版本低的错误

　　查看Node版本：node -v

　　在vscode中使用yarn ng generate module book  --module app --routing --route books

　　便会产生六个新文件，打开/src/app/book/book.module.ts并修改

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

@NgModule({
  declarations: [BookComponent],
  imports: [
    BookRoutingModule,
    SharedModule
  ]
})
export class BookModule { }

　　在app-routing.module.ts中添加路径

{ path: 'books', loadChildren: () => import('./book/book.module').then(m => m.BookModule) },

　　在route.provider.ts中修改

function configureRoutes(routes: RoutesService) {
  return () => {
    routes.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',
        parentName: '::Menu:BookStore',
        layout: eLayoutType.application,
      },
    ]);
  };
}

　　添加菜单目录

　　修改展示页面book.component.ts

import { ListService, PagedResultDto } from '@abp/ng.core';
import { Component, OnInit } from '@angular/core';
import { BookDto } from './models';
import { BookService } from './services';

@Component({
  selector: 'app-book',
  templateUrl: './book.component.html',
  styleUrls: ['./book.component.scss'],
  providers: [ListService],
})
export class BookComponent implements OnInit {
  book = { items: [], totalCount: 0 } as PagedResultDto<BookDto>;

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

  ngOnInit() {
    const bookStreamCreator = (query) => this.bookService.getListByInput(query);

    this.list.hookToQuery(bookStreamCreator).subscribe((response) => {
      this.book = response;
    });
  }
}

　　修改book.component.html

<div class="card">
  <div class="card-header">
    <div class="row">
      <div class="col col-md-6">
        <h5 class="card-title">
          {{ '::Menu:Books' | abpLocalization }}
        </h5>
      </div>
      <div class="text-right col col-md-6"></div>
    </div>
  </div>
  <div class="card-body">
    <ngx-datatable [rows]="book.items" [count]="book.totalCount" [list]="list" default>
      <ngx-datatable-column [name]="'::Name' | abpLocalization" prop="name"></ngx-datatable-column>
      <ngx-datatable-column [name]="'::Type' | abpLocalization" prop="type">
        <ng-template let-row="row" ngx-datatable-cell-template>
          {{ '::Enum:BookType:' + row.type | abpLocalization }}
        </ng-template>
      </ngx-datatable-column>
      <ngx-datatable-column [name]="'::PublishDate' | abpLocalization" prop="publishDate">
        <ng-template let-row="row" ngx-datatable-cell-template>
          {{ row.publishDate | date }}
        </ng-template>
      </ngx-datatable-column>
      <ngx-datatable-column [name]="'::Price' | abpLocalization" prop="price">
        <ng-template let-row="row" ngx-datatable-cell-template>
          {{ row.price | currency }}
        </ng-template>
      </ngx-datatable-column>
    </ngx-datatable>
  </div>
</div>
