如何使用HTTP拦截器在Angular应用程序中注入API密钥

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

@Injectable()
export class ApiKeyInterceptor implements HttpInterceptor {
  private apiKey = 'YOUR_API_KEY';

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const modifiedRequest = request.clone({
      headers: request.headers.set('Authorization', this.apiKey)
    });

    return next.handle(modifiedRequest);
  }
}

import { NgModule } from '@angular/core';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { ApiKeyInterceptor } from './api-key.interceptor';

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