如何从Gmail下载所有含附件的电子邮件? [英] How can I download all emails with attachments from Gmail?
问题描述
如何连接到Gmail并确定哪些邮件具有附件?然后我想下载每个附件,打印出每个消息的主题:和发件人:我处理它。 解决方案
一个: - )
import email,getpass,imaplib,os
detach_dir ='。'#
user = raw_input(输入您的GMail用户名:)
pwd = getpass.getpass(输入您的密码:)
#连接到gmail imap服务器
m = imaplib.IMAP4_SSL(imap.gmail.com)
m.login(user,pwd)
m.select([Gmail] /所有邮件)#在这里你可以选择一个像INBOX的邮箱,而不是
#使用m.list()获取所有邮箱
resp,items = m.search(None, ALL)#你可以在这里使用IMAP规则进行过滤(检查http://www.example-code.com/csharp/imap-search-critera.asp)
items = items [0] .split( )#获取邮件ID
用于emailid中的项目:
resp,data = m.fetch(emailid,(RFC822))#获取邮件, (RFC822)``意味着获得全部东西,但您只能要求标题等
email_body = data [0] [1]#获取邮件内容
mail = email.message_from_string( email_body)#解析邮件内容以获取邮件对象
#检查是否有附件
如果mail.get_content_maintype()!='multipart':
continue
print[+ mail [From] +]:+ mail [Subject]
#我们使用walk创建一个生成器,这样我们可以迭代():
#multipart只是容器,所以如果part.get_content_maintype()=='multipart',我们会跳过它们
, :
继续
#这部分是附件吗?
如果part.get('Content-Disposition')是None:
continue
filename = part.get_filename()
counter = 1
#如果没有文件名,我们用计数器创建一个以避免重复
,如果不是文件名:
filename ='part-%03d%s'%(counter,'bin')
counter + = 1
att_path = os.path.join(detach_dir,filename)
#检查它是否已经存在
如果不是os.path .isfile(att_path):
#最后编写东西
fp = open(att_path,'wb')
fp.write(part.get_payload(decode = True))
fp.close()
Wowww!那是一件事。 ;-)但是在Java中尝试一样,只是为了好玩!
顺便说一下,我在shell中测试过,所以有些错误可能会保留下来。
Enjoy
编辑:
因为邮箱名称可能会从一个国家变成另一个国家,所以我建议在 m之前选择
以避免此错误: m.list()
并在其中选取一个项目。选择(邮箱名称)
imaplib.error:命令SEARCH illegal in状态AUTH,只允许在
状态中选择
How do I connect to Gmail and determine which messages have attachments? I then want to download each attachment, printing out the Subject: and From: for each message as I process it.
Hard one :-)
import email, getpass, imaplib, os
detach_dir = '.' # directory where to save attachments (default: current)
user = raw_input("Enter your GMail username:")
pwd = getpass.getpass("Enter your password: ")
# connecting to the gmail imap server
m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(user,pwd)
m.select("[Gmail]/All Mail") # here you a can choose a mail box like INBOX instead
# use m.list() to get all the mailboxes
resp, items = m.search(None, "ALL") # you could filter using the IMAP rules here (check http://www.example-code.com/csharp/imap-search-critera.asp)
items = items[0].split() # getting the mails id
for emailid in items:
resp, data = m.fetch(emailid, "(RFC822)") # fetching the mail, "`(RFC822)`" means "get the whole stuff", but you can ask for headers only, etc
email_body = data[0][1] # getting the mail content
mail = email.message_from_string(email_body) # parsing the mail content to get a mail object
#Check if any attachments at all
if mail.get_content_maintype() != 'multipart':
continue
print "["+mail["From"]+"] :" + mail["Subject"]
# we use walk to create a generator so we can iterate on the parts and forget about the recursive headach
for part in mail.walk():
# multipart are just containers, so we skip them
if part.get_content_maintype() == 'multipart':
continue
# is this part an attachment ?
if part.get('Content-Disposition') is None:
continue
filename = part.get_filename()
counter = 1
# if there is no filename, we create one with a counter to avoid duplicates
if not filename:
filename = 'part-%03d%s' % (counter, 'bin')
counter += 1
att_path = os.path.join(detach_dir, filename)
#Check if its already there
if not os.path.isfile(att_path) :
# finally write the stuff
fp = open(att_path, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
Wowww! That was something. ;-) But try the same in Java, just for fun!
By the way, I tested that in a shell, so some errors likely remain.
Enjoy
EDIT:
Because mail-box names can change from one country to another, I recommend doing m.list()
and picking an item in it before m.select("the mailbox name")
to avoid this error:
imaplib.error: command SEARCH illegal in state AUTH, only allowed in states SELECTED
