uploadImage<T> method

Future<BaseEntity<T>> uploadImage<T>(String url, String filePath, AttachmentType attachmentType, { String? customAttachmentType, String? fileName, String mime = 'png', bool showProgress = false, bool isShow = false, ProgressCallback? onSendProgress, ProgressCallback? onReceiveProgress, CancelToken? cancelToken, Options? options, })

brief 上传图片 (通过Future方式请求，可以使用await阻塞直到获取到结果) @param url 接口地址 @param filePath 图片地址 @param attachmentType 上传附件类型 @param customAttachmentType 上传附件类型 (attachmentType为custom时，取customAttachmentType的值， 若为空默认为"system") @param fileName 图片名字 @param mime 图片格式 @param showProgress 是否显示上传进度 @param onSendProgress 发送文件进度回调 @param onReceiveProgress 接收文件进度回调 @param cancelToken 取消请求的token @param options 对请求的设置
