html - 在电子邮件中嵌入图像并通过 Powershell 发送

问题描述

我正在编辑我的一个旧脚本，以向用户发送一封电子邮件，其中嵌入了文本中的图像。我正在尝试使用 Send-MailMessage 功能来发送电子邮件，而不是旧的 $smtp.send($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图像。

注意：为简洁起见，我删除了一些完整的电子邮件，因为它很大，只要我能得到一两个图像，它就可以工作。

解决方案

所以真正的问题是如何将图像从附件嵌入到 HTML 文档中

CID aka Content 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 Content 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"

您正在使用

$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"

但是当您发送邮件时，您并没有附加这些附件

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

你可以停止使用Net.Mail.Attachment，而是做类似的事情

$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"
