如何确保curl请求通过angular获得附加的用户名和密码？

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpRequest, HttpHandler, HttpEvent } from '@angular/common/http';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // 添加附加的用户名和密码
    const username = 'your_username';
    const password = 'your_password';
    const authHeader = 'Basic ' + btoa(username + ':' + password);
    const authRequest = request.clone({
      headers: request.headers.set('Authorization', authHeader)
    });
    return next.handle(authRequest);
  }
}

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

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