# 連接到POP3服務器:
server = poplib.POP3(pop3_server)
# qq需要使用ssl
# server = poplib.POP3_SSL(pop3_server)
# 可以打開或關閉調試信息:
server.set_debuglevel(1)
# 可選:打印POP3服務器的歡迎文字:
print(server.getwelcome().decode('utf-8'))
# 身份認證:
server.user(email)
server.pass_(password)
# stat()返回郵件數量和占用空間:
print('Messages: %s. Size: %s' % server.stat())
# list()返回所有郵件的編號:
resp, mails, octets = server.list()
# 可以查看返回的列表類似[b'1 82923', b'2 2184', ...]
print(mails)
# 獲取最新一封郵件, 注意索引號從1開始:
index = len(mails)
resp, lines, octets = server.retr(index)
# lines存儲了郵件的原始文本的每一行,
# 可以獲得整個郵件的原始文本:
msg_content = b'\r\n'.join(lines).decode('utf-8')
# 稍后解析出郵件:
msg = Parser().parsestr(msg_content)
print_info(msg)
# 可以根據郵件索引號直接從服務器刪除郵件:
# server.dele(index)
# 關閉連接:
server.quit()
