问题描述
我需要将电子邮件数据库迁移到CRM并有两个问题：
I need to migrate an email database to a CRMand have 2 problems:
我可以访问mbox文件，但是内容没有正确解码。
I get to access the mbox file but the content is not properly decoded.
我想用以下几列创建一个类似数据框的结构：日期，从，到，主题，正文
I want to create a dataframe like structure with following columns: "date, from, to, subject, body"
我尝试了以下操作：
for i, message in enumerate(mbox):
print("from :",message['from'])
print("subject:",message['subject'])
if message.is_multipart():
content = (part.get_payload(decode=True) for part in message.get_payload())
else:
content = message.get_payload(decode=True)
print("content:",content)
print("**************************************")
if i == 10:
break
并获得以下输出：
from : =?UTF-8?Q?Gonzalo_Gasset_Yba=C3=B1ez?= <gonzalo.gasset@baud.es>
subject: =?UTF-8?Q?Marqu=C3=A9s_de_Vargas_=26_Baud?=
content: <generator object <genexpr> at 0x7fe025f3a350>
**************************************

推荐答案
mailbox.Mailbox 接受工厂可用于生成消息的参数。通过传递方法由 BytesParser = https://docs.python.org/3/library/email.policy.html#email.policy.default rel = nofollow noreferrer>默认政策，我们可以生成，它将自动解码标题和正文。
The concrete implementations of mailbox.Mailbox accept a factory argument that can be used to build messages. By passing the parse method of a BytesParser initialised with the default policy we can generate EmailMessages which will decode headers and body text automatically.
选择实际的正文比较棘手，并且可能取决于您的特定要求。在下面的代码示例中，任何文本都是字体部分连接在一起，而非文本部分则被拒绝。您可能希望应用自己的选择条件。
Selecting the actual body is trickier, and perhaps depends on your particular requirements. In the code sample below, any "text" type parts are joined together, while non-text parts are rejected. You might wish to apply your own selection criteria.
from email.parser import BytesParser
from email.policy import default
import mailbox
mbox = mailbox.mbox(path_to_mailbox, factory=BytesParser(policy=default).parse)
for _, message in enumerate(mbox):
print("date: :", message['date'])
print("to: :", message['to'])
print("from :", message['from'])
print("subject:", message['subject'])
if message.is_multipart():
contents = []
for part in message.walk():
maintype = part.get_content_maintype()
if maintype == 'multipart' or maintype != 'text':
# Reject containers and non-text types
continue
contents.append(part.get_content())
content = '\n\n'.join(contents)
else:
content = message.get_content()
print("content:", content)
print("**************************************")
