解决Angular的缓存问题的常用方法是使用HTTP拦截器。这可以在每个HTTP请求中添加或修改标头，从而防止浏览器缓存响应。以下是一个示例：

import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
 
@Injectable()
export class CacheInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest, next: HttpHandler): Observable> {
    request = request.clone({
      setHeaders: {
        'Cache-Control': 'no-cache',
        'Pragma': 'no-cache',
        'Expires': 'Sat, 01 Jan 2000 00:00:00 GMT'
      }
    });
 
    return next.handle(request);
  }
}

到了这儿，您需要在@ NgModule.providers中向您的应用程序添加拦截器，例如：

import { NgModule } from '@angular/core';
import { HTTP_INTERCEPTORS } from '@angular/common/http';
import { CacheInterceptor } from './cache.interceptor';
 
@NgModule({
  providers: [
    { provide: HTTP_INTERCEPTORS, useClass: CacheInterceptor, multi: true }
  ]
})
export class AppModule { }

现在，您已经成功地解决了Angular缓存问题，并可以在每个HTTP请求中添加或修改标头，从而防止浏览器缓存响应。
