在angular 2中将身份验证令牌添加到文件上传

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-file-upload',
  templateUrl: './file-upload.component.html',
  styleUrls: ['./file-upload.component.css']
})
export class FileUploadComponent {
  constructor(private http: HttpClient) {}

  onFileSelected(event: any) {
    const file: File = event.target.files[0];
    const formData: FormData = new FormData();
    formData.append('file', file);
    formData.append('token', localStorage.getItem('authToken')); // 添加身份验证令牌

    this.http.post('http://example.com/upload', formData)
      .subscribe(response => {
        console.log(response);
      });
  }
}
