问题描述
我最近使用AWS Transfer系列创建了一个SFTP站点。使用FileZilla，我可以连接到该站点，遍历目录，上传和下载文件而没有问题。但是，当我使用PHPseclib SFTP库时，我可以使用用户名/密码进行连接，但是rawlist()和nlist()返回的是false。我仔细研究了PHPseclib代码，发现真正的错误消息是“访问被拒绝的US-ASCII” 。我试图进行更深入的研究，但是我对SFTP / SSH通信还不够熟悉，无法理解我在看什么。任何对此的信息将不胜感激。
这是SFTP日志的结果：

解决方法
您使用了错误的路径。
使用GUI SFTP客户端登录并检查那里的路径。然后在您的PHP代码中使用相同的完整路径。
