Powershell

Question

我正在使用 powershell 脚本，该脚本将创建新部署的 VM 的 HTML 报告并将其作为电子邮件发送。到目前为止，我已经尝试了很多东西。但没有运气。不幸的是，我无法收到邮件。我哪里错了？以下是脚本的相关部分...

$Date = get-date
$Datefile = ( get-date ).ToString(‘yyyy-MM-dd-hhmmss’)
$ErrorActionPreference = "SilentlyContinue"
# Variable to change
$HTML = "yes"


#Add Text to the HTML file
Function Create-HTMLTable
{
param([array]$Array)
$arrHTML = $Array | ConvertTo-Html
$arrHTML[-1] = $arrHTML[-1].ToString().Replace(‘</body></html>’,"")
Return $arrHTML[5..2000]
}

$Header = "
<html><head></head><body>
<style>table{border-style:solid;border-width:1px;font-size:8pt;background-color:#ccc;width:100%;}th{text-align:left;}td{background-color:#fff;width:20%;border-style:so
lid;border-width:1px;}body{font-family:verdana;font-size:12pt;}h1{font-size:12pt;}h2{font-size:10pt;}</style>
<H1>VMware VM information</H1>
<H2>Date and time</H2>,$date
"


$Report = @()
Get-VM $row.ServerName | %

 {

  $vm = Get-View $_.ID
    $vms = "" | Select-Object VMName, Hostname, IPAddress
    $vms.VMName = $vm.Name
    $vms.Hostname = $vm.guest.hostname
$vms.IPAddress = $vm.guest.ipAddress

$Report += $vms
}

if ($HTML -eq "yes") {
$output += ‘<p>’
$output += ‘<H2>VMware VM information</H2>’
$output += ‘<p>’
$output += Create-HTMLTable $reports
$output += ‘</p>’
$output += ‘</body></html>’ }


Send-MailMessage -to $emailto -Subject $subject -SmtpServer $smtp -From $fromaddress -Body ($output) -BodyAsHtml

最后更新：

但是当我运行每次编写脚本时，我都会收到如下所示的重复邮件。听起来这些值附加到变量中。

邮件正文：

VMware VM information
Date and time
05/14/2020 17:24:51 
VMware VM information
VMName, Hostname, IPAddress
VM01,  Vm01 , xx.xx.xx.xx
VM02,  Vm02 , xx.xx.xx.xx
VMware VM information
VMName, Hostname, IPAddress
VM01,  Vm01 , xx.xx.xx.xx
VM02,  Vm02 , xx.xx.xx.xx

有几点感觉不对。

辅助函数 Create-HTMLTable 是用参数 $reports 调用的，但这是一个错字，因为该变量实际上被称为 $Report.
此外，该函数使用不带 -Fragment 开关的 ConvertTo-Html 从数组创建 html，然后尝试删除放入的额外 html。
使用 -Fragment 开关时，就不需要那个了。

接下来，在构建 $Report 时，您正在使用 $row.ServerName，但似乎从未定义过。

尝试：

$Date     = Get-Date
$Datefile = '{0:yyyy-MM-dd-hhmmss}' -f $Date    # not sure why you need this
$ErrorActionPreference = "SilentlyContinue"

# Variable to change. Make this a Boolean, so it can be used directly for the `BodyAsHTML` switch
$HTML = $true

# create Here-String templates for the HTML and for a plain-text output
$htmlBegin = @"
<html><head></head><body>
<style>
    table{border-style:solid;border-width:1px;font-size:8pt;background-color:#ccc;width:100%;}
    th{text-align:left;}td{background-color:#fff;width:20%;border-style:solid;border-width:1px;}
    body{font-family:verdana;font-size:12pt;}h1{font-size:12pt;}h2{font-size:10pt;}
</style>
<H1>VMware VM information</H1>
"@

# the placeholders '{0}' and '{1}' will be filled in later
$htmlEnd = @"
<H2>Date and time: {0}</H2>
<p></p>
<p>{1}</p>
</body></html>
"@

$plainText = @"
VMware VM information

Date and time: {0}

{1}
"@


# get the report for the VMs
$Report = Get-VM | ForEach-Object {
    Get-View $_.ID | Select-Object @{Name = 'VMName'; Expression = { $_.Name }},
                                   @{Name = 'Hostname'; Expression = { $_.guest.hostname }},
                                   @{Name = 'IPAddress'; Expression = { $_.guest.ipAddress }}
}

if ($HTML) {
    # convert the report into a HTML table. Use -Fragment to
    # just the HTML for the table; no '</body></html>'
    $table  = ($Report | ConvertTo-Html -Fragment) -join [Environment]::NewLine
    $output = $htmlBegin + ($htmlEnd -f $date, $table)
}
else {
    $table  = $Report | Format-Table -AutoSize | Out-String
    $output = $plainText -f $date, $table
}

# create a Hashtable for splatting the parameters to Send-MailMessage
$mailParams = @{
    To         = $emailto
    From       = $fromaddress
    Subject    = $subject
    SmtpServer = $smtp
    Body       = $output
    BodyAsHtml = $HTML  # $true of $false
}

Send-MailMessage @mailParams

HTML 输出应如下所示：

^{创建两个 HTML 模板的原因是我们希望能够使用占位符“{0}”和“{1}”，稍后使用 -f 格式运算符。因为在第一部分中有样式定义，也使用 { 和 } 字符，如果我们只在一个模板中这样做，所有这些现有的花括号都需要加倍，否则 -f 将无法找到并替换占位符。}
