在angular中的http头中添加“Bearer Token”

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

@Injectable()
export class TokenInterceptor implements HttpInterceptor {
  constructor() {}

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // 获取token
    const token = 'your_bearer_token';

    // 添加Bearer Token到请求头
    request = request.clone({
      setHeaders: {
        Authorization: `Bearer ${token}`
      }
    });

    return next.handle(request);
  }
}

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';

import { TokenInterceptor } from './token.interceptor';

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