如何将特定类型的所有文件上传到S3 Bucket？

当我这样做:

foreach ($f in (Get-ChildItem -filter "*.flv")){
    Write-S3Object -BucketName bucket.example -File $f.fullName -Key $f.name -CannedACLName PublicRead
}

我收到此错误:

Write-S3Object :
At line:1 char:51
+  foreach ($f in (Get-ChildItem -filter "*.flv")){ Write-S3Object -BucketName xx. ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (Amazon.PowerShe...eS3ObjectCmdlet:WriteS3ObjectCmdlet) [Write-S3Objec
   t], InvalidOperationException
    + FullyQualifiedErrorId : Amazon.S3.AmazonS3Exception,Amazon.PowerShell.Cmdlets.S3.WriteS3ObjectCmdlet

我究竟做错了什么？有什么我可以做的来看到更多的错误,或者这只是一个语法问题？

如何使用PowerShell将所有特定文件类型上传到存储桶？

编辑:

我故意设置Set-DefaultAWSRegion了一个桶不在的区域,并得到了

Write-S3Object : The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint. 

作为一个错误消息,正如预期的那样,所以看起来它可以连接到存储桶,它知道它不在某个区域.

此外,如果我s3://在存储桶名称前输入 前缀,我会收到一条消息,指出无法找到存储桶,因此看起来我现在输入的内容是正确的.

我可以执行Get-S3Bucket并查看我帐户中的所有存储桶,因此我知道它已正确配置.

EDIT2:

如果我做:

> $f = Get-ChildItem -filter "*.flv"
> Write-S3Object

cmdlet Write-S3Object at command pipeline position 1
Supply values for the following parameters:
BucketName: bucket.name
Key: $f[0].name
File: $f[0].fullName
Write-S3Object : The file indicated by the FilePath property does not exist!
At line:1 char:1
+ Write-S3Object
+ ~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (Amazon.PowerShe...eS3ObjectCmdlet:WriteS3ObjectCmdlet) [Write-S3Objec
   t], InvalidOperationException
    + FullyQualifiedErrorId : System.ArgumentException,Amazon.PowerShell.Cmdlets.S3.WriteS3ObjectCmdlet

如果我$f[0].fullName单独做,我会得到对象的完整路径.但是,它有空格.这可能是个问题吗？
