如何从angular向dotnet核心控制器发送文件

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

export class FileUploadComponent {
  constructor(private http: HttpClient) {}

  onFileSelected(event) {
    const file: File = event.target.files[0];
    const formData: FormData = new FormData();
    formData.append('file', file, file.name);

    this.http.post('/api/upload', formData).subscribe(
      (response) => {
        console.log('File uploaded successfully');
      },
      (error) => {
        console.error('Error uploading file');
      }
    );
  }
}

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;

[Route("api/[controller]")]
[ApiController]
public class UploadController : ControllerBase
{
  [HttpPost]
  public IActionResult Upload(IFormFile file)
  {
    // 处理文件，例如保存到服务器的特定位置
    // file.CopyTo(...);

    return Ok();
  }
}
