我正在尝试从gmail帐户中读取所有未读的电子邮件。 上面的代码可以建立连接,但无法获取电子邮件。
我要打印每封电子邮件的内容。
我收到错误消息,因为无法将int转换为字节。
代码:
import smtplib
import time
import imaplib
import email
def read_email_from_gmail():
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('my_mail','my_pwd')
mail.select('inbox')
result, data = mail.search(None, 'ALL')
mail_ids = data[0]
id_list = mail_ids.split()
first_email_id = int(id_list[0])
latest_email_id = int(id_list[-1])
for i in range(latest_email_id,first_email_id, -1):
result, data = mail.fetch(i, '(RFC822)' )
for response_part in data:
if isinstance(response_part, tuple):
msg = email.message_from_string(response_part[1])
email_subject = msg['subject']
email_from = msg['from']
print ('From : ' + email_from + '\n')
print ('Subject : ' + email_subject + '\n')
print(read_email_from_gmail())
错误:
Traceback (most recent call last):

我必须对您的代码进行一些更改才能使其在Python 3.5.1上运行。我在下面插入了注释。
# no need to import smtplib for this code
# no need to import time for this code
import imaplib
import email
def read_email_from_gmail():
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('my_mail','my_pwd')
mail.select('inbox')
result, data = mail.search(None, 'ALL')
mail_ids = data[0]
id_list = mail_ids.split()
first_email_id = int(id_list[0])
latest_email_id = int(id_list[-1])
for i in range(latest_email_id,first_email_id, -1):
# need str(i)
result, data = mail.fetch(str(i), '(RFC822)' )
for response_part in data:
if isinstance(response_part, tuple):
# from_bytes, not from_string
msg = email.message_from_bytes(response_part[1])
email_subject = msg['subject']
email_from = msg['from']
print ('From : ' + email_from + '\n')
print ('Subject : ' + email_subject + '\n')
# nothing to print here
read_email_from_gmail()
也许向该博客的作者提交错误报告。

这对我有用: 它将发件人地址,主题,内容(文本)存储到所有未读电子邮件的文件中。 代码:
import email
import imaplib
mail = imaplib.IMAP4_SSL('imap.gmail.com')
(retcode, capabilities) = mail.login('mymail','mypassword')
mail.list()
mail.select('inbox')
n=0
(retcode, messages) = mail.search(None, '(UNSEEN)')
if retcode == 'OK':
for num in messages[0].split() :
print ('Processing ')
n=n+1
typ, data = mail.fetch(num,'(RFC822)')
for response_part in data:
if isinstance(response_part, tuple):
original = email.message_from_bytes(response_part[1])
# print (original['From'])
# print (original['Subject'])
raw_email = data[0][1]
raw_email_string = raw_email.decode('utf-8')
email_message = email.message_from_string(raw_email_string)
for part in email_message.walk():
if (part.get_content_type() == "text/plain"): # ignore attachments/html
body = part.get_payload(decode=True)
save_string = str(r"C:\Users\devda\Desktop\Internship\Dumpemail_" + str('richboy') + ".txt" )
myfile = open(save_string, 'a')
myfile.write(original['From']+'\n')
myfile.write(original['Subject']+'\n')
myfile.write(body.decode('utf-8'))
myfile.write('**********\n')
myfile.close()
else:
continue
typ, data = mail.store(num,'+FLAGS','\\Seen')
print (n)
