在电子邮件中嵌入图像并通过PowerShell发送

我正在编辑我的一个旧脚本，以便向用户发送一封电子邮件，其中文本中嵌入了图像。我尝试使用Send-MailMessage函数来发送电子邮件，而不是使用旧的$smtp.send（$msg）方法。但是，当尝试更新脚本时，图像不再被嵌入。
我知道如何将它们作为实际的附件附加到电子邮件中，但我不确定我做错了什么，让它们显示为实际的嵌入式图像。
注意：为了简洁，我删除了一些完整的电子邮件，因为它很大，只要我能得到一个或两个图像的工作，它将全部工作。

因此，真实的的问题是如何将图像从附件嵌入到HTML文档中
CID又名内容ID将允许您附加图像，然后在文档中使用该附加图像。避免在内容ID名称中使用空格。

Send-MailMessage -To "Test@Test.com" -from "Test2@Test.com" -SmtpServer SMTP.TEST.NET -Subject "Hello" -BodyAsHtml -Body "<img src='cid:Test.png'>" -Port 25 -Attachments "C:\Users\Test\Test.png"

字符串
你在用

$att1 = new-object Net.Mail.Attachment ("T:\PS Scripts\Images\shareddrive1.png")
$att2 = new-object Net.Mail.Attachment ("T:\PS Scripts\Images\shareddrive2.png")
$att3 = new-object Net.Mail.Attachment ("T:\PS Scripts\Images\shareddrive3.png")
$att4 = new-object Net.Mail.Attachment ("T:\PS Scripts\Images\shareddrive4.png")
$att1.ContentId = "image1.png"
$att2.ContentId = "image2.png"
$att3.ContentId = "image3.png"
$att4.ContentId = "image4.png"

但是当你发送邮件时，你并没有附加那些附件

Send-MailMessage -To "<$UserID>" -bcc "<$Username@dana.com>" -from "<itservicedesk@x.com>" -Subject $global:subject -SmtpServer "mailrelay.x.com" -BodyAsHtml -body $global:body

您可以停止使用Net.Mail.Attachment，而是执行以下操作

$Body = @"
    <html>
        <body style="font-family:calibri"> 
            <b>This is image 1</b>
            <img src='cid:TEST1.png'>
            <b>This is image 2</b>
            <img src='cid:Test2.png'>
        </body>
    </html>
"@

Send-MailMessage -To "Test@Test.com" `
    -from "Test2@Test.com" `
    -SmtpServer Test.smtp.com `
    -Subject "Hello" `
    -BodyAsHtml -body $body `
    -Attachments "C:\Test\TEST1.png", "C:\Test\TEST2.png"

您可以将图像嵌入到HTML中，因此没有额外的文件。它正在取代

{img=file}

字符串
数据URL

{src="data:image/png;base64,[base64 encoded long string representing the image]}

有许多在线转换器可以将您的图像文件转换为所需的代码。

下面是一个使用MailKit的简单示例。我不得不从https://www.nuget.org/packages/MimeKit和https://www.nuget.org/packages/MailKit下载软件包，并使用7Zip解包，因为PowerShell正在努力从CLI安装。我从这里得到了一些想法，但想添加一个嵌入式图像https://adamtheautomator.com/powershell-email的示例。
你可以用MimeKit和MailKit做各种各样的事情，包括现代的Auth，这很棒。它也超级快，客户端甚至连接都可以在循环中使用，以发送大量消息。在不刷新的情况下使用连接的时间可能有一个上限？

$mailServer = "domain-com.mail.protection.outlook.com"

$SMTP = New-Object MailKit.Net.Smtp.SmtpClient

Add-Type -Path ".\mailkit.3.3.0\netstandard2.0\MailKit.dll"
Add-Type -Path ".\mimekit.3.3.0\netstandard2.0\MimeKit.dll"

$SMTP.Connect($mailServer, 25, [MailKit.Security.SecureSocketOptions]::StartTls, $False)

$Message  = New-Object MimeKit.MimeMessage
 
$message.From.Add("a.person@domain.com");
$message.To.Add("b.person@domain.com");
$message.Subject = "Some Subject";

$builder = [MimeKit.BodyBuilder]::new();

$image = $builder.LinkedResources.Add($path);
$image.ContentId = [MimeKit.Utils.MimeUtils]::GenerateMessageId();

$body = @"
    <html>
        <body style="font-family:calibri"> 
            <b>This is image 1</b>
            <img src='cid:$($image.ContentId)'>
        </body>
    </html>
"@

$builder.HtmlBody = $body

#Now we just need to set the message body and we're done
$message.Body = $builder.ToMessageBody();
$SMTP.Send($Message)

$SMTP.Disconnect($true)
$SMTP.Dispose()
