第一个导出的.csv文件（Report1第一天）
id principalName licenseDisplayName
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Basic
5b3556f1-df58-6c3c-848b-022fc6a8668d xyz@my.com Stackholder
6b3556f1-ff58-6c3c-848b-022fc6a8668d pqr@my.com Admin
另一天导出.csv文件（Report2第二天） idPrincipalName licenseDisplayName
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Stackholder
5b3556f1-df58-6c3c-848b-022fc6a8668d xyz@my.com Stackholder
8b3556f1-ff58-6c3c-848b-022fc6a8668d yz@my.com Basic
方案中，有使用PowerShell的每日导出报告。在上面的报告1和报告2中显示了记录。所以，我想要两个.csv文件之间的区别。
在Report2中，第一条记录从Basic更改为Stackholder，而第三条记录丢失了6b3556f1-ff58-6c3c-848b-022fc6a8668d，并添加了新记录8b3556f1-ff58-6c3c-848b-022fc6a8668d
我想要以下输出（两个.csv文件的区别）
id principalName licenseDisplayName Status
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Stackholder Updated from Basic to Stackholder
6b3556f1-ff58-6c3c-848b-022fc6a8668d pqr@my.com Admin Deleted
8b3556f1-ff58-6c3c-848b-022fc6a8668d yz@my.com Basic New
我的代码：
$reference = Import-Csv -Path C:\Documents\Daily_Report\Daily_Export_jsonold.csv
$lookup = $reference | Group-Object -AsHashTable -AsString -Property Server
$results = Import-Csv -Path C:\Documents\Daily_Report\Daily_Export_jsonnew.csv | foreach {
$server = $_.id
Write-Verbose "Looking for $server"
if ($lookup.value.ContainsKey($server))
{
$oldState = ($lookup[$server]).Access_Level
}
if ($_.State -ne $oldState)
{
[PSCustomObject]@{
id = $server
Username = $_.Username
OldState = $oldState
NewState = $_.Access_Level
}
}
}
但是我得到以下输出
id Username OldState NewState
-- -------- -------- --------
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Unknown Stakeholder
5b3556f1-df58-6c3c-848b-022fc6a8668d xyz@my.com Unknown Stakeholder
我希望它像下面这样：
id Username OldState NewState
-- -------- -------- --------
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Basic Stakeholder
5b3556f1-df58-6c3c-848b-022fc6a8668d xyz@my.com Stakeholder Stakeholder
答案 0 :(得分：0)
我建议让cmdlet Compare-Object完成工作的核心。
$Reference = Import-Csv '.\Daily_Export_jsonold.csv'
$Difference= Import-Csv '.\Daily_Export_jsonnew.csv'
Compare-Object -Ref $Reference -Diff $Difference `
-Property id,principalName,licenseDisplayName
示例输出：
id principalName licenseDisplayName SideIndicator
-- ------------- ------------------ -------------
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Stackholder =>
8b3556f1-ff58-6c3c-848b-022fc6a8668d yz@my.com Basic =>
4b3556f1-df58-6c3c-848b-022fc6a8668d abc@my.com Basic <=
6b3556f1-ff58-6c3c-848b-022fc6a8668d pqr@my.com Admin <=
这与您想要的结果非常接近，按属性id进行分组可以得出：
Count Name Group
----- ---- -----
2 4b3556f1-df58-6c3c-848... {@{id=4b3556f1-df58-6c3c-848b-022fc6a8668d; principalName=abc@my.com; licenseDisplayName=Stackho...
1 8b3556f1-ff58-6c3c-848... {@{id=8b3556f1-ff58-6c3c-848b-022fc6a8668d; principalName=yz@my.com; licenseDisplayName=Basic; S...
1 6b3556f1-ff58-6c3c-848... {@{id=6b3556f1-ff58-6c3c-848b-022fc6a8668d; principalName=pqr@my.com; licenseDisplayName=Admin; ...
这里：
'<='表示“已删除” '=>'表示“新建” 所以这个脚本：
## Q:\Test\2019\05\28\SO_56341395.ps1
$Reference = Import-Csv '.\Daily_Export_jsonOld.csv'
$Difference= Import-Csv '.\Daily_Export_jsonNew.csv'
$Result = Compare-Object -Ref $Reference -Diff $Difference `
-Property id,principalName,licenseDisplayName |
Group-Object id | ForEach-Object {
if ($_.Count -gt 1){
$Status = 'Updated from {0}' -f $_.Group[1].licenseDisplayName
} elseif ($_.Group[0].SideIndicator -eq '<='){
$Status = 'Deleted'
} else {
$Status = 'New'
}
[PSCustomObject]@{
id = $_.Group[0].id
principalName = $_.Group[0].principalName
licenseDisplayName = $_.Group[0].licenseDisplayName
Status = $Status
}
}
$Result | Sort-Object id
$Result | Sort-Object id| Export-Csv '.\Daily_Export_jsonDif.csv' -NoTypeInformation
提供此输出：
> Q:\Test\2019\05\28\SO_56341395.ps1
id principalName licenseDisplayName Status
