我的代码出了什么问题。未使用react native中的多部分将数据发送或上载到服务器

const uploadFile = async (uri, formData) => {
  const options = {
    method: 'POST',
    body: formData,
    headers: {
      'Content-Type': 'multipart/form-data',
    },
  };

  try {
    const response = await fetch('YOUR_UPLOAD_ENDPOINT', options);
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    const jsonResponse = await response.json();
    return jsonResponse;
  } catch (error) {
    console.error('There has been a problem with your fetch operation:', error);
  }
};

const createFormData = (photoUri, body = {}) => {
  const data = new FormData();

  data.append('photo', {
    name: 'photo.jpg',
    type: 'image/jpeg',
    uri: Platform.OS === 'android' ? photoUri : photoUri.replace('file://', ''),
  });

  Object.keys(body).forEach((key) => {
    data.append(key, body[key]);
  });

  return data;
};

// 使用示例
const photoUri = 'file://path/to/photo.jpg';
const formData = createFormData(photoUri, { description: 'A beautiful photo' });
uploadFile(photoUri, formData);
