如何将电子邮件主题从"？UTF-8？...？="转换为可读字符串？

Question

可能重复:
字符串编码/解码

现在主题看起来像:=？UTF-8？B？0J/RgNC + 0LLQtdGA0LrQsA ==？=

Answer 1

也许你可以使用decode_header函数:http://docs.python.org/library/email.header.html#email.header.decode_header

Answer 2

=?UTF-8?B?和之间的部分?=是base64编码的字符串.提取该部分,然后解码它.

import base64

#My buggy SSH account needs this to write unicode output, you hopefully won't
import sys
import codecs
sys.stdout = codecs.getwriter('utf-8')(sys.stdout)


encoded = '=?UTF-8?B?0J/RgNC+0LLQtdGA0LrQsA==?='
prefix = '=?UTF-8?B?'
suffix = '?='

#extract the data part of the string
middle = encoded[len(prefix):len(encoded)-len(suffix)]
print "Middle: %s" % middle

#decode the bytes
decoded = base64.b64decode(middle)
#decode the utf-8
decoded = unicode(decoded, 'utf8')

print "Decoded: %s" % decoded

输出:

Middle: 0J/RgNC+0LLQtdGA0LrQsA==
Decoded: ????????
