PowerShell - 连接两个 HTML 表

问题描述 投票：0回答：1

我必须停止应用程序服务并启动它们，中间有 3 分钟的延迟。必须在邮件中捕获此状态。下面是代码。

#Connect to Azure Account
Connect-AzAccount -Identity -AccountID '1234'

#Get subscription ID
$subscriptionID = (Get-AzSubscription).Id

#Get resource group
$resourceGroup = (Get-AzResourceGroup).ResourceGroupName

#Get env from resource group
$env = $resourceGroup -split '-'
$env = $env[-1].ToUpper()

#Get current time in EST
$currentTime = Get-Date
$currentTimeEST = [System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId((Get-Date -Date $currentTime), 'Eastern Standard Time')

#Mail parameters
$destEmailAddress = "ABC"
$fromEmailAddress = "XYZ"
$subjectLine = "Restart Status [Env: $env]"
$ccEmailAddress1 = ""
$ccEmailAddress2 = ""
$ccEmailAddress3 = ""
$bccEmailAddress = ""

# Initialize an empty string to store the email body as HTML
$emailBody = "<html><head><style>table { border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; }</style></head><body>"
$emailBody += "<p><b>Dear Team,</b><br><br><b>Below is the status of function and web app(s) restart as of $currentTimeEST (EST).</b></p>"
$emailBody += "<table><tr><th>App Name</th><th>Stop Time</th><th>Stop Status</th><th>Start Time</th><th>Start Status</th></tr>"


# Get all function and web apps in the resource group
$appNames = Get-AzWebApp -ResourceGroupName $resourceGroup | where-object {$_.State -eq "Running"}

# Restart each Function/Web App
foreach ($appName in $appNames) {
    try{
        $appName = $appName.Name
        Write-Output "Stopping App: $appName."
        $stopTime = Get-Date
        $stopTime = [System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId((Get-Date -Date $stopTime), 'Eastern Standard Time')
        Stop-AzWebApp -Name $appName -ResourceGroupName $resourceGroup
        Write-Output "$appName is stopped."
        $stopStatus = (Get-AzWebApp -ResourceGroupName $resourceGroup -Name $appName).State

        Write-Output "Starting App: $appName."
        $startTime = Get-Date
        $startTime = [System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId((Get-Date -Date $startTime), 'Eastern Standard Time')
        Start-AzWebApp -Name $appName -ResourceGroupName $resourceGroup 
        Write-Output "$appName is started."
        $startStatus = (Get-AzWebApp -ResourceGroupName $resourceGroup -Name $appName).State

        # Append information to email body
        $emailBody += "<tr><td>$appName</td><td>$stopTime</td><td>$stopStatus</td><td>$startTime</td><td>$startStatus</td></tr>"
    }catch{
        Write-Host "An error occurred: $_.Exception.Message"
    }
    
}

# Final email body
$emailBody += "</table><p><b>Thanks,<br/>ABC</b></p></body></html>"

# Pass parameters to another runbook
$runbookParams = @{
    destEmailAddress = $destEmailAddress
    fromEmailAddress = $fromEmailAddress
    ccEmailAddress1 = $ccEmailAddress1
    ccEmailAddress2 = $ccEmailAddress2
    ccEmailAddress3 = $ccEmailAddress3
    bccEmailAddress = $bccEmailAddress
    subject = $subjectLine
    content = $emailBody
}


Start-AzAutomationRunbook -AutomationAccountName "automationacc" -Name "send-sendgrid-email-parameter" -ResourceGroupName $resourceGroup -Parameters $runbookParams

要求： 我必须立即停止所有功能应用程序，等待 3 分钟，然后启动所有功能应用程序。我认为 for 循环应该分为 2 个循环（一个用于停止，一个用于开始），在两者之间我们使用 Start-sleep。但对于电子邮件内容，我如何在一张表中捕获所有这些状态。应该像下面这样。

如果你真的想将重启循环一分为二，你可以尝试这个（未经测试）

# Connect to Azure Account
Connect-AzAccount -Identity -AccountID '1234'

# Get subscription ID
$subscriptionID = (Get-AzSubscription).Id
# Get resource group
$resourceGroup = (Get-AzResourceGroup).ResourceGroupName
# Get env from resource group
# changed '$env' into '$rgEnv' to not confuse with PowerShell $env: variables
$rgEnv = ($resourceGroup -split '-')[-1].ToUpper()
# Get current time in EST
$currentTimeEST = [System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId((Get-Date), 'Eastern Standard Time')

# Mail parameters
$destEmailAddress = "ABC"
$fromEmailAddress = "XYZ"
$subjectLine      = "Restart Status [Env: $rgEnv]"
$ccEmailAddress1  = ""
$ccEmailAddress2  = ""
$ccEmailAddress3  = ""
$bccEmailAddress  = ""


# Initialize a template here-string to store the email body as HTML
$emailBody = @"
<html><head>
<style>
    table { border-collapse: collapse; } 
    th, td { border: 1px solid black; padding: 8px; }
</style>
</head><body>
<p><b>Dear Team,</b><br><br><b>Below is the status of function and web app(s) restart as of $currentTimeEST (EST).</b></p>
<table><tr><th>App Name</th><th>Stop Time</th><th>Stop Status</th><th>Start Time</th><th>Start Status</th></tr>
{0}
</table><p><b>Thanks,<br/>ABC</b></p></body></html>
