arrays - Angular，无法从 Web 服务 (JSON) 获取值列表
问题描述
我正在尝试从 JSON 网络服务获取孩子的列表，在登录过程中，我得到了一个 JSON 响应的名字......以及特定医生的孩子列表。我在控制台中有响应，但由于某种原因，当我尝试在 HTML 文件中显示它时，我没有这样做。这是我的 kidsdetails.component.ts：

这是医生模型：
export class Doctor {
public createdAt:string ;
public firstName:string;
public id: string;
public kids: Array<Kid>;
public lastName:string;
public login: string;
public mail: string;
public password: string;
public phoneNumber:string;
public photo: string;
public token: string;
public updatedAt: string;
}
这是服务：我通过getUsers()方法获取医生，因为我无法直接访问孩子的列表：
import {HttpClient, HttpHeaders} from '@angular/common/http';
import {environment} from '../../environments/environment';
import {UserService} from './user.service';
import {Router} from '@angular/router';
@Injectable({
providedIn: 'root'
})
export class KidsService {
private readonly proxy: string = environment.usersWebServices;
private readonly proxyTrace: string = environment.traceWebServices;
private readonly imageServer: string = environment.uploadWebServices;
constructor(private http: HttpClient,
private service: UserService,
private route: Router) { }
private get JsonType() {
const headers = new HttpHeaders({ Authorization : 'Bearer ' + localStorage.getItem('access') });
// headers.append({'Authorization': ''});
return headers;
}
public getUsers() {
return this.http.get(`${this.proxy}/doctor`, { headers : this.JsonType });
}
getUser(id) {
// authentication/id
return this.http.get(`${this.proxy}/user/${id}`, { headers : this.JsonType });
}
onLogout() {
localStorage.removeItem('token');
this.route.navigateByUrl('/authentication/login');
}
getKidGames( idUser, idKid ) {
return this.http.get(`${this.proxyTrace}/dataoutput/evaluation/${idUser}/${idKid}`, { headers : this.JsonType });
}
consumeKid(pinCode) {
const idDoctor = this.service.getUserDetails().unique_name;
return this.http.get(`${this.proxy}/kidcode/consume/${pinCode}/${idDoctor}`);
}
addNote( idKid, idUser, text ) {
const obj = { text , idKid , idUser};
return this.http.post(`${this.proxy}/doctornote`, obj, { headers : this.JsonType });
}
getKidNotes(idUser, idKid) {
return this.http.get(`${this.proxy}/doctornote/bykid/${idUser}/${idKid}`, {headers : this.JsonType});
}
getKidImage(id) {
return this.http.get(`${this.imageServer}/upload/${id}`, {headers : this.JsonType});
}
}
