请帮助使用Flutter和Laravel上传文件

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

void uploadFile() async {
  var file = File('path/to/file'); // 选择要上传的文件
  var url = 'http://your-laravel-server/upload'; // 替换为Laravel后端的上传接口地址

  // 使用http包进行文件上传
  var request = http.MultipartRequest('POST', Uri.parse(url));
  request.files.add(await http.MultipartFile.fromPath('file', file.path));
  var response = await request.send();
  if (response.statusCode == 200) {
    print('文件上传成功');
  } else {
    print('文件上传失败');
  }

  // 使用dio包进行文件上传
  var dio = Dio();
  var formData = FormData.fromMap({'file': await MultipartFile.fromFile(file.path)});
  var response = await dio.post(url, data: formData);
  if (response.statusCode == 200) {
    print('文件上传成功');
  } else {
    print('文件上传失败');
  }
}

public function upload(Request $request)
{
    if ($request->hasFile('file')) {
        $file = $request->file('file');
        if ($file->isValid()) {
            $path = $file->store('uploads'); // 将文件移动到指定的存储位置
            return response()->json(['path' => $path]);
        }
    }
    return response()->json(['error' => '文件上传失败']);
}
