我正在使用英雄聯(lián)盟 API，更具體地說是他們帶來的冠軍 json。我用 Angular 提供了這項(xiàng)服務(wù)：import { Injectable } from '@angular/core';import { HttpClient, HttpHeaders} from '@angular/common/http';const httpOptions = {  headers: new HttpHeaders({'Content-Type': 'application/json'})}@Injectable({  providedIn: 'root'})export class ChampionsService {  constructor(private http: HttpClient) { }  getChampions(){    return this.http.get('http://ddragon.leagueoflegends.com/cdn/10.23.1/data/es_ES/champion.json');  }}這是我的 .ts 文件：import { Component, OnInit } from '@angular/core';import {ChampionsService } from '../../services/champions.service';@Component({  selector: 'app-champions',  templateUrl: './champions.component.html',  styleUrls: ['./champions.component.css']})export class ChampionsComponent implements OnInit {  public champions;  public arrayChampions;      constructor(private championsService:ChampionsService) { }  ngOnInit(): void {    this.getAllChampions();  }  getAllChampions(){    this.championsService.getChampions().subscribe(      data => { this.champions = data,         this.arrayChampions = Object.entries(this.champions.data).map(([k,v]) => ({ [k]:v })),        this.ArrayIterator();       },      err => {console.error(err)},      () => console.log("Champions cargados")    );  }  ArrayIterator() {    let IteratableArray = Array();    for (let item of Object.keys(this.arrayChampions[0])) {      var eventItem = Object.values(this.arrayChampions[0]);      IteratableArray.push(eventItem);    }    this.arrayChampions = IteratableArray[0];  }}正如你所看到的，var“arrayChampions”只會(huì)帶來第一個(gè)冠軍（Atrox），而據(jù)我所知，它應(yīng)該帶來所有冠軍（我是 javascript 和 Angular 的新手）。
