错误错误：找不到类型为“对象”（角度）的其他支持对象“ [对象对象]”

Question

创建此程序时，标题中出现错误。我尝试使用Angular从REST API获取一些信息。我附加了服务，组件中的ts和html。我为此使用rxjs和Observable。我将服务注入到构造函数中。我将不胜感激。谢谢！

import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs';
import { HeroService } from './services/hero.service';
import {Customer} from './models/customer';

@Component({
  selector: 'app-hero',
  templateUrl: './hero.component.html',
  styleUrls: ['./hero.component.scss']
})
export class HeroComponent implements OnInit {

  private ndg: string;
  public customerData;

  constructor(private heroService: HeroService) {
     this.ndg='117158101';
   }

  ngOnInit() {
      this.heroService.getCustomerInfo(this.ndg)
        .subscribe(data => { this.customerData=data,
          console.log(this.customerData)
        }, error => console.log(error));
    }
}

import { Injectable } from '@angular/core';
import { ApiService } from '../../../../services/base.services';
import { Observable } from 'rxjs';
import { environment } from '../../../../../../environments/environment';
import {Customer} from '../models/customer';

@Injectable({
  providedIn: 'root'
})
export class HeroService {

  constructor(private apiService: ApiService) { }

  getCustomerInfo(ndg: string) {
    const url = `${environment.apiUrl}${environment.ur3Path}cifCustomerDetails/customers/${ndg}`;
    return this.apiService.get(url);
  }
}

<!--
 --   Hero component
-->

<section class="hero">
  <div class="content-hero" *ngFor="let customer of customerData">
    <h1>Welcome to your loan <br/> application, {{customer.name}}</h1>
    <h4>Your RM today is Sandra Menter.</h4>
  </div>
</section>

Answer 1

ngFor是一种用于复制多个元素的标签的结构，就像您有大量客户一样。在您的情况下，无需使用它，它应该像这样简单：

<section class="hero">
  <div class="content-hero">
    <h1>Welcome to your loan <br/> application, {{customerData.customer.name}}</h1>
    <h4>Your RM today is Sandra Menter.</h4>
  </div>
</section>
