import 'package:http/http.dart' as http;

Future<void> sendImageWithPost() async {
  var url = 'YOUR_RESTFUL_API_URL';
  
  // 读取图像文件
  var imageBytes = await File('PATH_TO_IMAGE').readAsBytes();
  
  // 构建请求体
  var request = http.MultipartRequest('POST', Uri.parse(url));
  request.files.add(http.MultipartFile.fromBytes('image', imageBytes, filename: 'image.jpg'));
  
  // 发送请求
  var response = await request.send();
  
  // 获取响应
  if (response.statusCode == 200) {
    print('Image uploaded successfully');
  } else {
    print('Failed to upload image');
  }
