如何在angular中正确调用拦截器中的服务方法

// 1. 创建拦截器服务
@Injectable()
export class MyInterceptor implements HttpInterceptor {
  constructor(private myService: MyService) {}

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // 在拦截器中调用服务方法
    this.myService.doSomething();

    // 继续处理请求
    return next.handle(request);
  }
}

// 2. 注册拦截器服务
@NgModule({
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: MyInterceptor,
      multi: true
    }
  ]
})
export class AppModule {}

// 3. 创建服务方法
@Injectable()
export class MyService {
  constructor(private http: HttpClient) {}

  doSomething() {
    // 执行需要在拦截器中调用的逻辑，比如发送HTTP请求
    this.http.get('https://example.com/api/data').subscribe(response => {
      // 处理响应
    });
  }
}
