# Angular 2中数据映射为特定对象类型的方法

typescript
export class User {
  name: string;
  age: number;
  constructor(name: string, age: number) {
    this.name = name;
    this.age = age;
  }
}

typescript
import { Injectable } from '@angular/core';
import { User } from './user.model';
@Injectable({
  providedIn: 'root',
})
export class DataMappingService {
  mapToUser(data: any): User {
    return new User(data.name, data.age);
  }
}

typescript
import { Component, OnInit } from '@angular/core';
import { DataMappingService } from './data-mapping.service';
@Component({
  selector: 'app-user',
  templateUrl: './user.component.html',
  styleUrls: ['./user.component.css'],
})
export class UserComponent implements OnInit {
  userData: any; // 假设从API获取的原始数据
  user: User;
  constructor(private dataMappingService: DataMappingService) {}
  ngOnInit(): void {
    this.user = this.dataMappingService.mapToUser(this.userData);
  }
}
