phpseclib rawlist() returns 错误
phpseclib rawlist() returns false
我最近使用 AWS Transfer 系列创建了一个 SFTP 站点。使用 FileZilla，我可以毫无问题地连接到站点、遍历目录、上传和下载文件。但是，当我使用 phpseclib SFTP 库时，我可以连接 username/password，但 rawlist() 和 nlist() 返回 false。我仔细研究了 phpseclib 代码，发现真正的错误消息是 "Access deniedUS-ASCII"。我试图深入挖掘，但我对 SFTP/SSH 通信不够熟悉，无法理解我在看什么。任何有关这方面的信息将不胜感激。

您使用的路径错误。
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。
我最近使用 AWS Transfer 系列创建了一个 SFTP 站点。使用 FileZilla，我可以毫无问题地连接到站点、遍历目录、上传和下载文件。但是，当我使用 phpseclib SFTP 库时，我可以连接 username/password，但 rawlist() 和 nlist() 返回 false。我仔细研究了 phpseclib 代码，发现真正的错误消息是 "Access deniedUS-ASCII"。我试图深入挖掘，但我对 SFTP/SSH 通信不够熟悉，无法理解我在看什么。任何有关这方面的信息将不胜感激。
