在Angular Interceptor中如何处理恢复

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent } from '@angular/common/http';
import { Observable } from 'rxjs';
import { retry, delay, tap } from 'rxjs/operators';

@Injectable()
export class RetryInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(request).pipe(
      retry(3), // 最大重试次数为3次
      delay(1000), // 重试之间的延迟时间为1秒
      tap(() => console.log('重试请求')), // 在每次重试之前记录一条日志
    );
  }
}

import { NgModule } from '@angular/core';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { RetryInterceptor } from './retry.interceptor';

@NgModule({
  imports: [HttpClientModule],
  providers: [
    { provide: HTTP_INTERCEPTORS, useClass: RetryInterceptor, multi: true }
  ]
})
export class AppModule { }
