在Angular中使用缓存自定义favIcon.icon加载错误

<link rel="icon" type="image/x-icon" href="path/to/favIcon.icon">

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

constructor(private http: HttpClient) {}

loadFavIcon() {
  this.http.get('path/to/favIcon.icon', { responseType: 'blob', observe: 'response', cache: 'default' })
    .subscribe(response => {
      if (response.status === 200) {
        // 处理加载成功的情况
      } else {
        // 处理加载失败的情况
      }
    });
}

import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent, HttpErrorResponse } from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { catchError } from 'rxjs/operators';

@Injectable()
export class ErrorInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(request).pipe(
      catchError((error: HttpErrorResponse) => {
        // 处理错误
        return throwError(error);
      })
    );
  }
}
