我正在嘗試在 TXT 檔案中決議 Mimefile，格式如下
Content-Type: multipart/related; boundary="MIMEBoundary"
MIME-Version: 1.0

我想分離 XML 并將其編碼為單獨的字串，我是如何制作這樣的解碼器的
class NewlineSafeBytesParser(email.parser.BytesParser):
def parse(self, fp, headersonly=False):
from io import TextIOWrapper
fp = TextIOWrapper(fp, encoding='ascii', errors='surrogateescape', newline='')
try:
return self.parser.parse(fp, headersonly)
finally:
fp.detach()
# Subclassing:
parser = NewlineSafeBytesParser()
但我得到一個損壞的解碼結果，如何將編碼的 zip 檔案（Base64）編碼與 txt 檔案分開，以便可以單獨解碼？
uj5u.com熱心網友回復：
在 python3 上決議并僅顯示Content-Type: text/xml
mailFile = open("list1.txt", "rb").read()
msg = email.message_from_file(mailFile)
for part in msg.walk():
print(part.get_content_type())
if part.get_content_type() == 'text/xml':
print(part.get_payload())
<?xml version='1.0' encoding='UTF-8'?>
