如何使用MailMessage将图像嵌入PowerShell电子邮件中

问题描述

我有一封来自PS的电子邮件。我一直在试图做的是在电子邮件中嵌入图像（不包括附件）。以下是我到目前为止：

I have an email that works from PS. What I have been trying to do is include images embedded in the email (not attachments). Below is what I have so far:

function Email
        {
            $smtpServer = {smtp server}
            $smtpFrom = {email from}
            $smtpTo = {email to}
            $messageSubject = "test"

            $message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto
            $message.Subject = $messageSubject
            $message.IsBodyHTML = $true
            $credentials=new-object system.net.networkcredential({smtpUsername},{smtpPassword})

             # $message.Body = Get-Content "D:\Program Files\CymbaTech_FBNC_AM\CTDataLoader\data\TestBody.html"

        # The line below will add any attachments you have such as log files.
        $message.Attachments.Add("{path}\Image1.png")
        $message.Body = '<img src="cid:xyz">'

            $smtp = New-Object Net.Mail.SmtpClient($smtpServer)
            $smtp.credentials=$credentials.getcredential($smtpserver,"25","basic")
            $smtp.Send($message)
        }

在上面，我添加了图像标签到Body.html文件。如果我直接打开html，它看起来像预期的图像显示正确。

In the above, I have added image tags to the Body.html file. If I open the html directly, it looks as expected with images showing correctly.

然而，当我发送邮件时，图像显示为带有边框的白色框。似乎该脚本没有加载文件中的图像。

When I send the mail however, the images are just displayed as white boxes with a border. Seems that the script is not loading the images in the file.

有没有人做过类似的事情，并有任何建议？

Has anyone done similar before and have any suggestions?

推荐答案

您必须将图片添加为常规附件。然后，HTML主体必须通过cid属性引用这些附件：< img src =cid：xyz> 其中xyz是Content-ID的值附件MIME部分的MIME属性。

You must add images as regular attachments. The HTML body must then reference these attachments though the cid attribute: <img src="cid:xyz"> where "xyz" is the value of the Content-ID MIME attribute on the attachment MIME part.
