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 m.list()并在其中选取一个项目。选择(邮箱名称)以避免此错误:


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.

解决方案

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
