PowerShell生成VM快照报告并邮件发送脚本报错求助

错误原因 #

你遇到的语法错误，核心是HTML样式变量$style的连续赋值语句在同一行未用分号分隔，PowerShell无法正确解析连续的赋值操作，从而抛出Unexpected token '$style'错误。

修复方案 #

推荐使用PowerShell的Here-String定义完整CSS样式，代码更易读且不易出错；也可以给同一行的赋值语句添加分号分隔。以下是两种修复方式：

方式1：使用Here-String（推荐）

直接用多行字符串定义完整的CSS样式，避免拼接错误：

#HTML formatting
$style = @"
<style>
BODY{font-family: Arial; font-size: 10pt;}
TABLE{border: 1px solid red; border-collapse: collapse;}
TH{border: 1px solid; background-color: #4CAF50; color: white; padding: 5px; }
TD{border: 1px solid; padding: 5px; }
</style>
"@
$date = Get-Date -Format "dddd dd/MM/yyyy HH:mm K"

方式2：分号分隔同一行的赋值语句

如果坚持原有的拼接方式，需在每个$style赋值之间添加分号：

#HTML formatting
$style = "BODY{font-family: Arial; font-size: 10pt;}"; $style = $style + "TABLE{border: 1px solid red; border-collapse: collapse;}"; $style = $style + "TH{border: 1px solid; background-color: #4CAF50; color: white; padding: 5px; }"; $style = $style + "TD{border: 1px solid; padding: 5px; }"; $style = $style + ""
$date = Get-Date -Format "dddd dd/MM/yyyy HH:mm K"

完整修复后的脚本 #

以下是替换$style部分后的完整可运行脚本：

#Variables
$vCenter = "qwe-2019.wer.com"
$vCenterUser = "wer\adm-myuser"
$vCenterPass = "balabala"
$SMTPServer = "***********.com"
$To = "************.com"
$From = "***********.com"

#HTML formatting
$style = @"
<style>
BODY{font-family: Arial; font-size: 10pt;}
TABLE{border: 1px solid red; border-collapse: collapse;}
TH{border: 1px solid; background-color: #4CAF50; color: white; padding: 5px; }
TD{border: 1px solid; padding: 5px; }
</style>
"@
$date = Get-Date -Format "dddd dd/MM/yyyy HH:mm K"

#Connect to vCenter
CLS
Write-Host "Connecting to $vCenter" -ForegroundColor Blue
Connect-VIServer -Server $vCenter -User $vCenterUser -Password $vCenterPass -Force | Out-Null
Write-Host " Connected to $vCenter" -ForegroundColor Green

#Get list of VMs with snapshots
Write-Host "Generating VM snapshot report" -ForegroundColor Blue
$SnapshotReport = Get-vm | Get-Snapshot | Select-Object VM,Description,PowerState,SizeGB | Sort-Object SizeGB | ConvertTo-Html -Head $style | Out-String
Write-Host " Completed" -ForegroundColor Green

#Sending email report
Write-Host "Sending VM snapshot report" -ForegroundColor Blue
$htmlbody = @"
$SnapshotReport
"@
Send-MailMessage -smtpserver $SMTPServer -From $From -To $To -Subject "Snapshot Email Report for $Date" -BodyAsHtml -Body $htmlbody
Write-Host " Completed" -ForegroundColor Green

#Disconnecting vCenter
Disconnect-VIServer -Server $vCenter -Force -Confirm:$false
Write-Host "Disconnected from $vCenter" -ForegroundColor Blue

（注：最后一行的Disconnecting to改为Disconnected from，更符合语义）

验证说明 #

修复后，PowerShell能正确解析CSS样式的定义，生成带格式的HTML快照报告并发送邮件。
