FTPReply.isPositiveCompletion介绍

[英]Determine if a reply code is a positive completion response. All codes beginning with a 2 are positive completion responses. The FTP server will send a positive completion response on the final successful completion of a command.
[中]确定回复代码是否为肯定完成响应。所有以2开头的代码都是肯定的完成响应。FTP服务器将在命令最终成功完成时发送肯定的完成响应。
