WinSCP ExecuteCommand报告IsSuccess = true但ExitCode = 1

Posted 2021-05-07

我试图使用Powershell的WinSCP连接到Ubuntu机器，上传shell脚本并运行它。在脚本中我有set -o errexit以确保它在失败时停止。我无意中在运行脚本时忘记使用sudo，因此像chmod u=rwx,g=,o= some-folder这样的命令失败，因为不允许SSH用户这样做。这是预期的，我可以看到脚本已经终止了它应该。

然而，从Powershell，我做了类似的事情：

$session = New-Object WinSCP.Session
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp;
    HostName = $HostName
    UserName = $UserName
    SshPrivateKeyPath = $SshPrivateKeyPath
    SshHostKeyFingerprint = $SshHostKeyFingerprint
}

$session.Open($sessionOptions)
...

$result = $session.ExecuteCommand("$remoteScriptPath '$argument1' '$argument2'")

# In the scenario above I would expect the Check() to fail.
# Instead it moves on without any visible errors.
$result.Check()

如上所述，Check()没有失败，所以我尝试调试并注意到$result看起来像：

[DBG]: PS D:>> $result

Output      : Some command output ...
              Some other command output ...
              ...
ErrorOutput : chmod: changing permissions of 'some-folder': Operation not permitted
ExitCode    : 1
Failures    : {}
IsSuccess   : True

这对我来说非常违反直觉。当IsSuccess不为0且ExitCode不为空时，ErrorOutput如何才真实？它是WinSCP中的错误还是我不理解的功能？

更新：按建议附加会话日志文件...

答案

实际上，默认情况下，WinSCP不会将退出代码1视为错误。

使用WinSCP 5.14.1 beta及更高版本，您可以使用raw session settings ExitCode1IsError更改它：

$sessionOptions.AddRawSettings("ExitCode1IsError", "1")
