问题描述

如何在 SFTP 中传输二进制文件?它会和普通文件一样吗?或者有什么不同的流程?

How to transfer binary file in SFTP? Will it be same as normal file? Or is there any different process?

推荐答案

二进制文件是普通文件.

A binary file is a normal file.

您可能指的是 FTP 协议中已知的文本/ascii 与二进制传输模式.FTP 协议默认为 text/ascii 模式，因此通常必须确保将模式切换为二进制模式，以免损坏传输的二进制文件.

You are possibly referring to a text/ascii vs. a binary transfer mode, known from an FTP protocol. The FTP protocol defaults to the text/ascii mode, so one usually had to ensure that the mode was switched to the binary not to corrupt the transferred binary files.

SFTP 协议在其较新版本中还支持文本/ascii 与二进制模式的区别.尽管与 FTP 相反，二进制模式是默认模式，如果需要，必须明确强制使用 text/ascii 模式.

SFTP protocol also supports a text/ascii vs. binary mode distinction in its newer versions. Though contrary to the FTP, the binary mode is the default and one has to explicitly force the text/ascii mode, if desired.

此外，仅 SFTP 版本 4 及更新版本支持 ascii/text 模式.许多 SFTP 服务器/客户端(包括最广泛使用的 OpenSSH)仅支持 SFTP 版本 3.所以他们甚至不会让你使用 text/ascii 模式.

Moreover the ascii/text mode is supported by an SFTP version 4 and newer only. And many SFTP servers/clients (including the most widespread one, the OpenSSH) support an SFTP version 3 only. So they will not even let you use the text/ascii mode.
