Python 电子邮件消息Django错误上带有附加_文件的UnicodeEncodeError

因此，当我尝试用Django中的EmailMessage发送电子邮件时，会出现此错误

UNICODEENCODEER在/签出时出错/

'ascii' codec can't encode character u'\u0161' in position 15:

消息体包含一些中断脚本的unicode字符

问题是，如果我省略了附件，或者如果正文不包含任何unicode字符，那么一切都可以正常工作。主题可以包含无unicode错误的unicode字符。因此，它只能与正文和附加文件中的unicode字符结合使用。这对我来说似乎是一个错误

附件是生成的pdf文件

运行在Ubuntu 10.04、apache2、mod_wsgi、python 2.6.5、Django 1.5上的代码

我使用的代码是

t = loader.get_template('orders/invoice_email.html')
c = {
    'order': order,
}

email = EmailMessage(subject, t.render(Context(c)), from_mail, [to, ])
email.encoding = "utf-8"
email.content_subtype = "html"
email.attach_file(invoice.name)
email.send()

还有追踪

因此，在不断尝试之后，我找到了一个适合我的解决方案

t = loader.get_template('orders/invoice_email.html')
c = {
        'order': order,
    }

body = u''.join(t.render(Context(c))).encode('utf-8').strip()
email = EmailMessage(subject, body, from_mail, [to, ])
email.encoding = "utf-8"
email.content_subtype = "html"
email.attach_file(invoice.name, mimetype="application/pdf")
email.send()

如果有人有同样的问题，我希望这会有所帮助。

您能找出发生错误的代码吗？然后我们可以试着四处转转。完整的代码对我来说很难自己执行。你每次都尝试使用相同的文件吗？@User我不知道如何进一步隔离它。脚本试图发送电子邮件时会发生错误。@Samuele Mattiuzzo随附的pdf是一份生成的发票，是的，如果您是这样问的话，我已经用不同的文件尝试过了。如果代码中出现任何

unicode

字符串，您能否尝试

.encode（'utf8'）

它？
