当angular项目超时时如何停止显示异常？

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) {}

// 发起HTTP请求
this.http.get('https://api.example.com/data', { timeout: 5000 })
  .subscribe(
    response => {
      // 处理响应数据
    },
    error => {
      // 处理错误
    }
  );

import { Component } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <div *ngIf="!timeoutError">
      <!-- 显示正常内容 -->
    </div>
    <div *ngIf="timeoutError">
      <!-- 显示超时提示信息 -->
      <p>请求超时，请稍后重试。</p>
    </div>
  `
})
export class ExampleComponent {
  timeoutError = false;

  constructor(private http: HttpClient) {}

  fetchData() {
    this.http.get('https://api.example.com/data', { timeout: 5000 })
      .subscribe(
        response => {
          // 处理响应数据
          this.timeoutError = false; // 请求成功，隐藏超时提示信息
        },
        error => {
          // 处理错误
          if (error.name === 'TimeoutError') {
            this.timeoutError = true; // 请求超时，显示超时提示信息
          }
        }
      );
  }
}
