Angular拦截器不重新提交失败的请求

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

@Injectable()
export class RetryInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(request).pipe(
      retry(2), // 设置最大重试次数为2次
      catchError((error: HttpErrorResponse) => {
        if (error.status === 0) {
          // 请求失败，重新提交
          return next.handle(request);
        } else {
          // 其他错误，抛出异常
          return throwError(error);
        }
      })
