我正在尝试使用python的Template对象来创建HTML电子邮件。但是,当应用尝试发送电子邮件时,我收到错误:

File "/base/data/home/apps/hanksandbox/1.350486862928605153/main.py", line 573, in post
html = messages.email_document_html(document)
File "/base/data/home/apps/hanksandbox/1.350486862928605153/messages.py", line 109, in email_document_html
description = document.get_description()
File "/base/python_runtime/python_dist/lib/python2.5/string.py", line 170, in substitute
return self.pattern.sub(convert, self.template)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 763: ordinal not in range(128)

错误引用的代码如下:

def email_document_html(document):
email_document = Template("""
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    ${stylesheet}
</head>
<html>
<body>
<h1 id="mainhead">Essays</h1>
<div class="document">
<span class="info">At ${date} ${author} published:</span><br/><hr/>
<a href="${domain}/${author}/document/${filename}/" target="_blank"><h1 class="title">${title}</h1></a>
<p class="description">${description}</p>
</div>
</body>
</html>
""")
return email_document.substitute(
                                 stylesheet=style,
                                 date=str(document.date),
                                 author=document.author.username,
                                 domain=domainstring,
                                 filename=document.filename,
                                 title=document.title,
                                 description = document.get_description()
                                 )

我的IDE使用UTF-8作为其字符集。我已尝试将# coding: utf-8添加到我的文件中。我尝试在各种地方添加.encode("utf-8").decode("utf-8"),特别是在'document.get_description()'之后。但我正在抓住稻草。

有什么建议吗?

到处使用unicode

email_document = Template(u"""

答案 1 :(得分:2)

在模板字符串之前加上u,以指定它是一个unicode字符串。 Python&lt;除非另有说明,否则3将字符串解释为ASCII。

email_document = Template(u"""
