当命令行包含空格时，带有参数的Powershell中的AWS CLI AWS RunRemoteScript返回错误

Question

我的目标是使用PowerShell自动化一些AWS过程。

其中一个步骤是从远程位置在EC2 Windows机器上执行ps1脚本(在我的例子中是S3(。

问题是脚本必须使用强制参数运行。只要命令包含空格，CLI就会抛出：

aws ssm send-command --region us-west-2 --targets Key=tag:T,Values=V --document-name "AWS-RunRemoteScript" --parameters '{"sourceType":["S3"],"sourceInfo":["{\"path\":\"https://bucketName.s3-us-west-2.amazonaws.com/folder/Install.ps1\"}"],"commandLine":[".\Install.ps1 -Param1 value"]}'

返回

aws : usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
At line:1 char:1
+ aws ssm send-command --region us-west-2 --targets Key=tag:T,Values=V  ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (usage: aws [opt....] [parameters]:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help
Unknown options: -Param1, value"]}

而在没有CCD_ 2的情况下工作良好。即使在"命令行"的末尾添加空格也会导致问题

... "commandLine":[".\Install.ps1 "]}'与... Unknown options: "]}的结果

我怀疑这是某种PowerShell语法/转义问题，因为相同的命令(具有正确的转义(在bash控制台上工作。

参考官方文档，它应该在bashshell上工作，但我找不到powershell的任何工作示例。。。。

以下是bash shell中的工作原理：aws ssm send-command --region us-west-2 --targets Key=tag:T,Values=V --document-name "AWS-RunRemoteScript" --parameters '{"sourceType":["S3"],"sourceInfo":["{"path":"https://bucketNameXX.s3-us-west-2.amazonaws.com/folder/Install.ps1"}"],"commandLine":[".Install.ps1 -Param1 value"]}'

删除了所有转义符，除了双引号洞察"sourceInfo"值的转义符。

$aws ssm send-command --region us-west-2 --targets Key=tag:T,Values=V --document-name "AWS-RunRemoteScript" --parameters '{"sourceType":["S3"],"sourceInfo":["{"path":"https://bucketName.s3-us-west-2.amazonaws.com/folder/Install.ps1"}"],"commandLine":[".Install.ps1 -Param1 value"]}'
