我尝试使用Angular的HttpClient发送带有授权标头的请求,但标头未成功设置.

在这里我的代码.

import {HttpClient, HttpHeaders} from '@angular/common/http';


constructor(private http: HttpClient,
            private auth: AuthService) {
}

sendRequest() {
  this.http.get(this.url, {
    headers: new HttpHeaders().set('Authorization', 'Bearer ' + this.auth.getAccessToken())
  }).subscribe(
    data => {
      console.log(data);
    },
    error => {
      console.log(error);
    }
  );
}

这里是网络调试头源.

响应头如下.
