将文件从SD卡上传到FileZilla Server

Question

我的应用程序是将文件从SD卡上传到FileZilla FTP Server上的目录.运行我的appliaction后,它给了我一些异常,我在搜索后无法解决这个问题.

这是log cat输出:

        Toast.makeText(MainActivity.this, "sent", Toast.LENGTH_LONG).show();
        }
        }

Answer 1

SimpleFTP 库的实现似乎不符合 FTP 规范（RFC 959）。根据此处找到的来源，它期望 FTP 服务器的初始回复开始"220 "，而 RFC 指定FTP 回复由三位数字（作为三个字母数字字符传输）和后跟一些文本组成。"220-"因此，允许以 开头的回复。

我建议使用更好的 FTP 库，例如apache commons ftp或ftp4j。
