如何将图像从Ionic 3应用程序上传到内置ASP.NET核心的How服务器？

import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';

// ...

constructor(private transfer: FileTransfer, private file: File) { }

uploadImage() {
  let options: FileUploadOptions = {
    fileKey: 'image',
    fileName: 'image.jpg',
    chunkedMode: false,
    mimeType: 'image/jpeg'
  };

  const fileTransfer: FileTransferObject = this.transfer.create();

  fileTransfer.onProgress((progressEvent) => {
    // 显示上传进度
    let progress = Math.round((progressEvent.loaded / progressEvent.total) * 100);
    console.log('Upload progress: ' + progress + '%');
  });

  fileTransfer.upload('<path_to_image_file>', '<server_url>', options)
    .then((data) => {
      // 上传成功
      console.log('Image uploaded successfully');
    }, (err) => {
      // 上传失败
      console.log('Error uploading image: ' + err);
    });
}

[HttpPost]
public IActionResult UploadImage(IFormFile image)
{
    if (image != null && image.Length > 0)
    {
        var filePath = "<path_to_save_image>";
        using (var stream = new FileStream(filePath, FileMode.Create))
        {
            image.CopyTo(stream);
        }
        // 进一步处理图像文件
        // ...
        return Ok();
    }
    else
    {
        return BadRequest();
    }
}
