如何在python中使用imaplib获取电子邮件正文？

不…

imaplib

是一个非常不错的库，它的imap太难以理解了。

您可能希望检查一下

t == 'OK'

，但是

data[0][1]

可以像我用过的一样工作。

这是我用来提取通过电子邮件收到的签名证书的快速示例，虽然不是防d的，但适合我的目的：

import getpass, os, imaplib, emailfrom OpenSSL.crypto import load_certificate, FILETYPE_PEMdef getMsgs(servername="myimapserverfqdn"):  usernm = getpass.getuser()  passwd = getpass.getpass()  subject = 'Your SSL Certificate'  conn = imaplib.IMAP4_SSL(servername)  conn.login(usernm,passwd)  conn.select('Inbox')  typ, data = conn.search(None,'(UNSEEN SUBJECT "%s")' % subject)  for num in data[0].split():    typ, data = conn.fetch(num,'(RFC822)')    msg = email.message_from_string(data[0][1])    typ, data = conn.store(num,'-FLAGS','\Seen')    yield msgdef getAttachment(msg,check):  for part in msg.walk():    if part.get_content_type() == 'application/octet-stream':      if check(part.get_filename()):        return part.get_payload(depre=1)if __name__ == '__main__':  for msg in getMsgs():    payload = getAttachment(msg,lambda x: x.endswith('.pem'))    if not payload:      continue    try:      cert = load_certificate(FILETYPE_PEM,payload)    except:      cert = None    if cert:      cn = cert.get_subject().commonName      filename = "%s.pem" % cn      if not os.path.exists(filename):        open(filename,'w').write(payload)        print "Writing to %s" % filename      else:        print "%s already exists" % filename
