  name: string
  path: string
}[]> {
  return new Promise((resolve, reject) => {
    Taro.chooseMessageFile({

如何使用

apiUploadImage(user.token, 1, 1).then((data) => {
            if (data.length) {
                activeRoute.readBookImg = data[0].filePath
                activeRoute.readBookImgPathUrls = data[0].fileUrl
            }
            setActiveRoute({ ...activeRoute })
    });
