SFTP在VBA中上传

Question

下面的Dode不会返回错误，或“成功”或“失败”，但它也不起作用 - 资本化的子TestUpload中的信息是我改变发布此信息的唯一信息 - 其他一切都是合法的 - 提前致谢。

WinINet功能不支持SFTP协议（FTP协议完全不同）。

在VBA和Windows API中都没有对SFTP的本机支持。您必须使用第三方库或软件。

有关示例，请参阅以下问题：

• 使用WinSCP脚本：Using VBA to run WinSCP script
• 使用WinSCP .NET程序集：Getting "user defined type not defined" when trying to use WinSCP .NET assembly in VBA to upload file to SFTP
