Question

我正在尝试将图像嵌入电子邮件中。我遵循了示例here，here和here以及其他示例，但是我无法显示图像。

settings.json

执行此操作时，我得到一个空的身体，上面有一个红色的十字，没有图像。如何使图像与电子邮件正文内嵌显示？

我正在使用Outlook2016。我知道我可以在使用Outlook本身时插入图片，并且收到“正常”电子邮件，其他人在文本中插入了图像，因此，这肯定意味着我必须能够查看从python生成的图像脚本？

编辑：我研究了给定的here解决方案，建议将其作为可能的重复方案，但这也没有解决我的问题。

我也尝试过将相同的电子邮件发送到Gmail和Hotmail帐户，并且仍然出现相同的问题，因此问题显然与代码有关。

我在Outlook 2013中找到了解决方案：

Outlook似乎在寻找span标记以及一些图像信息，例如高度和宽度（目前为硬编码）和id等（请参见下文）。我将图像包装在此html文本中，然后还添加了图像作为附件使用与cid和id相同的编号。图像然后在Outlook中显示为嵌入式文件。

    # loop through all uploaded files and add as attachments
    for index, file in enumerate(attachment):
       with open(file, "rb") as fp:
          data = fp.read()
          fileType = os.path.splitext(file)[-1].strip(".")

          ctype, _ = mimetypes.guess_type(file)

          if embedImages and "image/" in ctype:
             image = Image.open(data)
             # Build out the html for the email
             message += '<span style = "mso-no-proof:yes"><img width = 1280 height = 1920 id = "%s" src = "cid:%s"></span>' % (index, index)
             # Define the image's ID
             msgImage = MIMEImage(data, _subtype=fileType)
             msgImage.add_header('Content-ID', '<%s>' % index)
             msg.attach(msgImage)
             att = MIMEApplication(data, _subtype=fileType)
             att.add_header("Content-Disposition", "attachment", filename="%s" % index)
             msg.attach(att)
        else:
             att = MIMEApplication(data, _subtype=fileType)
             att.add_header("Content-Disposition", "attachment", filename=fileName)
             msg.attach(att)
        fp.close()

        # Attach html text
        if message:
            if embedImages or "mimeType" in kwargs:
                msg.attach(MIMEText(message, kwargs["mimeType"], 'utf-8'))
            else:
                msg.attach(MIMEText(message, "plain", 'utf-8'))

这是另一个使用MIMEMultipart（'related'）的解决方案，因此您不必在Outlook中处理跨度。适用于任何类型的多个附件。（除非另有说明，否则图像将被嵌入）

    # Determine attach type - defaults to attached only
    embedImages = kwargs["embedImages"] if "embedImages" in kwargs else False

    # Create the root message and fill in the from, and subject headers
    msgRoot = MIMEMultipart('related')
    msgRoot["Subject"] = subject
    msgRoot["From"] = kwargs["fromAddr"] if "fromAddr" in kwargs else noreply

    # Encapsulate the plain and HTML versions of the message body in an
    # 'alternative' part, so message agents can decide which they want to display.
    msgAlternative = MIMEMultipart('alternative')
    msgRoot.attach(msgAlternative)

    # Get Recipient Type
    recipientType = kwargs.get("recipientType")

    # Chunk Process Recipients
    batchSize = 100
    for i in range(0, len(recipientList), batchSize):
        # Handle 100 recipients at a time
        recipients = recipientList[i:i + batchSize]
        # Set the to, bcc or cc in root message
        if recipientType == "bcc":
            msgRoot["Bcc"] = ", ".join(recipients)
        elif recipientType == "cc":
            msgRoot["Cc"] = ", ".join(recipients)
        else:
            msgRoot["To"] = ", ".join(recipients)

        # Add Attachments
        if attachment and isinstance(attachment, str):
            # For backwards compatibility turn single attachment into a list
            attachment = [attachment]

        # loop through all uploaded files and add as attachments
        for index, file in enumerate(attachment):
            with open(file, "rb") as fp:
                # guess the file type from mimetypes
                ctype, _ = mimetypes.guess_type(file)
                if embedImages and "image/" in ctype:
                    # Build out the html for the email
                    message += '<p><img src="cid:%s"></p>' % index
                    msgImage = MIMEImage(fp.read())
                    # Define the image's ID in header
                    msgImage.add_header('Content-ID', '<%s>' % index)
                    # attach it to root
                    msgRoot.attach(msgImage)
                else:
                    fileName = alias if alias and len(attachment) == 1 else os.path.basename(file)
                    msgApp = MIMEApplication(fp.read())
                    # define header as attachment
                    msgApp.add_header("Content-Disposition", "attachment", filename=fileName)
                    # attach it to root
                    msgRoot.attach(msgApp)
                # close the file handle
                fp.close()

        # Attach html text
        if message:
            if embedImages or "mimeType" in kwargs:
                msgAlternative.attach(MIMEText(message, kwargs["mimeType"], 'utf-8'))
            else:
                msgAlternative.attach(MIMEText(message, "plain", 'utf-8'))

MIMEImage没有显示在电子邮件正文中/试图在电子邮件中嵌入图像
