Angular/Typescript，在http错误回调中调用订阅者的下一个错误回调

import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import { catchError } from 'rxjs/operators';
import { throwError } from 'rxjs';

// 在某个服务或组件中
constructor(private http: HttpClient) {}

handleError(error: HttpErrorResponse) {
  // 执行自定义的错误处理逻辑
  console.error('An error occurred:', error.message);
  
  // 调用订阅者的下一个错误回调
  return throwError(error);
}

makeHttpRequest() {
  this.http.get('https://api.example.com/data')
    .pipe(
      catchError(this.handleError)
    )
    .subscribe(
      response => {
        // 处理成功的响应
      },
      error => {
        // 处理错误的响应
      }
    );
}
