Maybe I'm just not understanding how to use the Read method for the File object, but I see in docs that io.Reader is within the multipart.File interface, but I don't understand how to access it. Any guidance would be greatly appreciated.

multipart.Fileinterface includes theio.Readerinterface, so any object that is a validmultipart.Fileis also a validio.Reader. Therefore, you can call theReadmethod (as defined byio.Reader) on an object of typemultipart.File.本回答被题主选为最佳回答 , 对您是否有帮助呢?评论 打赏解决 1无用 1举报 分享
