如何使用ionic将图片文件上传到服务器？

import { Component } from '@angular/core';
import { FileTransfer, FileUploadOptions, FileTransferObject } from '@ionic-native/file-transfer/ngx';

@Component({
  selector: 'app-upload',
  templateUrl: './upload.page.html',
  styleUrls: ['./upload.page.scss'],
})
export class UploadPage {
  constructor(private fileTransfer: FileTransfer) {}

  uploadImage() {
    const fileTransfer: FileTransferObject = this.fileTransfer.create();

    // 设置上传的URL地址
    const url = 'http://example.com/upload';

    // 获取选择的图片文件的本地路径
    const filePath = 'path/to/image.jpg';

    // 设置上传参数
    const options: FileUploadOptions = {
      fileKey: 'file',
      fileName: 'image.jpg',
      headers: {},
    };

    // 开始上传
    fileTransfer.upload(filePath, url, options)
      .then((data) => {
        // 上传成功，处理服务器返回的响应结果
        console.log(data.response);
      })
      .catch((error) => {
        // 上传失败，处理错误信息
        console.error(error);
      });
  }
}
