【中文标题】尝试发送电子邮件附件时出错

【英文标题】：Error while trying to send an email attachment

【发布时间】：2019-01-11 20:27:21

【问题描述】：

我正在尝试发送包含文本和附件的电子邮件并遇到以下错误？

删除以下块可以发送电子邮件但无法发送附件，任何人都可以提供有关如何修复它的指导吗？

   f = file(attachment_file_path )
    attachment = MIMEText(f.read())
    attachment.add_header('Content-Disposition', 'attachment', filename=attachment_file_path)           
    msg.attach(attachment)

代码：-

导入操作系统，smtplib 导入子流程，pprint，shlex 从子流程导入 Popen、PIPE、调用 从 email.mime.text 导入 MIMEText 从 email.MIMEMultipart 导入 MIMEMultipart

def sendEmail(type,data):
    global originalradar
    global gerriturl,email,username
    body = '''%s''' % (data)
    msg = MIMEMultipart(body)
    # sender = '[e-mail]'
    sender = '[e-mail]'
    receivers = ['[e-mail]']
    #sendEmail(data)
    attachment_file_path = './wifi_projects/wifi-ci/.git/rebase-apply/patch'
    if type =='cherrypickfailure':
        msg['Subject'] = 'CHERRYPICK FAILED '

    msg['From'] = sender
    msg['To'] = ', '.join(receivers)
    try:
        mail = smtplib.SMTP('relay.company.com', 25)
        f = file(attachment_file_path )
        attachment = MIMEMultipart(f.read())
        attachment.add_header('Content-Disposition', 'attachment', filename=attachment_file_path)           
        msg.attach(attachment)
        msg.attach(MIMEText(body))
        mail.sendmail(sender, receivers, msg.as_string())
        print 'Email sent successfully'
    except Exception as e:
        print e

conflictedblocks = 'README': '<<<<<<< HEAD\nTRP\n=======\nTBD\n>>>>>>> <rdar://problem/42841519> Dummy radar\n'
conflictedblocks_string = ""
for key,value in conflictedblocks.items():
    conflictedblocks_string +=  "<b><u>" +key + "</b></u>" +":" + "\n" + value + "\n"


sendEmail('cherrypickfailure',conflictedblocks_string)

错误：-

Cannot attach additional subparts to non-multipart/*

【参考方案1】：

您的msg 对象是MIMEText 类型。您需要一个 MIMEMultipart 对象才能添加附件。

按照@stark 的建议添加消息正文：

body = 'Your body content'
msg.attach(MIMEText(body))

检查this great tutorial，它谈到发送带有附件的邮件。

【讨论】：

我改成attachment = MIMEMultipart(f.read())，也没用

我也改成了msg = MIMEMultipart(body)，我得到了错误string payload expected: <type 'list'>

msg 应该是两个 MIMEText 的列表

@dashboard ,@stark ：在您的建议没有帮助之后，我用我的最新代码更新了这个问题......您能否更具体地说明需要更改的内容？

我用msg.attach(MIMEText(body)) 更新了我的代码并更新了问题，它没有帮助..我错过了什么？我应该删除任何东西吗？
