Question

我在ssh上运行powershell脚本为"jobs": { // Here i need [ instead of {, how can i fix it? "2": { "working": "1" }, "5": { "working": "4" }, "6": { "working": "3" } } $return = array("jobs" => $return, "testing" => 'testing');。只要我开始传递参数，它就会按预期工作。

当我将其作为ssh user@host "powershell -Comand - < script.ps1时，它会失败（如文档所述）powershell -Command - my args

虽然'-' was specified with the -Command parameter; no other arguments to -Command are permitted.的另一种方式失败了：

powershell my args -Command -

我打算在没有任何解析的情况下输入任意参数列表。

修改

当我进一步调查时，即使明确指定了命令，我似乎也在做错事：

The term 'my' is not recognized as the name of a cmdlet, function, script file,
 or operable program. Check the spelling of the name, or if a path was included
, verify that the path is correct and try again.
At line:1 char:3
    + my <<<<  args -Command -
    + CategoryInfo          : ObjectNotFound: (my:String) [], CommandNotFoundE 
   xception
    + FullyQualifiedErrorId : CommandNotFoundException

似乎没有传递任何参数，但出于某种原因它们会被打印在控制台上。避免使用ssh似乎没有任何改变：

(local bash) $ echo '\n' | ssh -i master-key Admin@10.8.55.78 '$SYSTEMROOT/System32/WindowsPowerShell/v1.0/powershell' -Command 'Write-Host \$\(\$args.Count\)' "my" "args"
0 my args

Answer 1

你不能直接这样做，但我认为如果你将脚本包装在scriptblock中并将参数传递给它，我可以这样做：

echo "& { $(cat script.ps1) } 'my' 'args'" | ssh user@host "powershell -Command"

由于-Command参数无法处理多行字符串，因此有一种方法可以使用Base64编码的-EncodedCommand参数值将其传入（虽然不是通过标准输入），但它很难看：

ssh user@host "powershell -encodedcommand $((echo "& {"; cat script.ps1 ; echo "} 'my' 'args'") |  iconv -f ascii -t utf-16le | base64 -w0 ; echo -e "\n")

Answer 2

这一工作正常：

script=$(cat <<-'SCRIPT'
{ 
    $a=$Args[0];
    $b=$Args[1];
    # Do not enclose $script into "" to avoid this comment spread till the EOL
    Write-Host "This is 'a': $a";
    Write-Host "This is 'b': $b";
} # <- call as [[[ -c "& { $script } ... " ]]] if you ommit braces '{}' here 
SCRIPT
)
a="THE VALUE OF THE \"a\""
b="B B B B"
powershell -nologo -executionpolicy bypass  -c "& $script '$a' '$b'"

输出：

> This is 'a': THE VALUE OF THE "a"
> This is 'b': B B B B

在从标准输入解释脚本时如何将参数传递给powershell命令
