在Angular中添加头部'Authorization‘

ng generate interceptor auth

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

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // 在请求头中添加'Authorization'字段
    const authReq = req.clone({
      headers: req.headers.set('Authorization', 'Bearer your_token_here')
    });

    // 继续处理修改后的请求
    return next.handle(authReq);
  }
}

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

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