Javascript 无法以 reactnative 发送表单数据

I was using axios to send form-data in RN but it's not working. Noww tried fetch every feild uploads except images. If i use postman, everything works fine.

这是我的代码:

const postOrder = () => {
    var data = new FormData();
    data.append('marca', marca);
    data.append('modeo', modeo);
    data.append('option', option);
    data.append('descripcion', descripcion);
    data.append('images[]', images);
    data.append('userId', '2');
    dispatch(saveOrder(data));
  };
    fetch(`${baseUrl}/save-order`, {
    method: 'POST',
    headers: {
      Accept: 'application/json',
      'Content-Type': 'multipart/form-data',
    },
    body: data,
  })
    .then(res => res.json())
    .then(json => {
      // dispatch({type: 'ORDER', payload: response.data});
      console.log('json1', json);
    })
    .catch(error => {
      console.log(error);
    });

除图片外，所有房产/场地均已上传.我也try 过这些方法

data.append('file', {
      uri: images,
      type: 'image/jpeg',
      name: 'images[]',
    });
data.append('file',images,'images[])
