为此，你需要控制传输的两端，是吗？
如果是这样你必须在请求中发送偏离
文件，然后照常获取字节，并将它们附加到
文件。

For this to work you need to control both ends of the transmition, do you?
if so you would have to send in the request the offset from the beginning of
the file, after that is as usual, get the bytes, and append them to the
file.

我相信你可以使用HTTP。 1.1规范中有一个
条款（以我认为的标题形式），你可以设置为
表示从哪里开始下载。通过这种方式，您可以指示要从哪个
字节开始，然后只需附加到您的文件。
希望这会有所帮助。

I believe you can use HTTP for this. The 1.1 specification has a
provision in it (in the form of a header I believe) which you can set to
indicate where to start the download from. This way, you can indicate which
byte to start at, and then just append to your file.
Hope this helps.

此标题称为范围。使用它，可以指定要检索的一个或多个
字节段。
干杯，
