python3 使用多线程将mailbox_list = ['Drafts', 'INBOX', 'Sent', 'Trash', 'Spam']邮箱中的文件存储到本地 # 邮箱登录信息 IMAP_SERVER = 'imap.aliyun.com' EMAIL_ACCOUNT = 'qwerty2132@aliyun.com' EMAIL_PASSWORD = 'abc.1906'

可以使用以下代码实现该功能:
```python
import threading
import email
import imaplib
import os
# 邮箱登录信息
IMAP_SERVER = 'imap.aliyun.com'
EMAIL_ACCOUNT = 'qwerty2132@aliyun.com'
EMAIL_PASSWORD = 'abc.1906'
# 存储路径
SAVE_PATH = './emails/'
# 邮箱列表
mailbox_list = ['Drafts', 'INBOX', 'Sent', 'Trash', 'Spam']
# 线程数
NUM_THREADS = 5
def save_email_to_file(mailbox, email_id, email_data):
"""
将邮件保存到文件
"""
filename = '{}_{}.eml'.format(mailbox, email_id)
filepath = os.path.join(SAVE_PATH, filename)
with open(filepath, 'wb') as f:
f.write(email_data)
def fetch_emails(mailbox, start, end):
"""
下载并保存邮件
"""
conn = imaplib.IMAP4_SSL(IMAP_SERVER)
conn.login(EMAIL_ACCOUNT, EMAIL_PASSWORD)
conn.select(mailbox=mailbox, readonly=True)
status, messages = conn.search(None, 'ALL')
message_ids = messages[0].split()[start:end]
for message_id in message_ids:
status, email_data = conn.fetch(message_id, '(RFC822)')
email_data = email_data[0][1]
save_email_to_file(mailbox, message_id, email_data)
conn.close()
def download_emails():
"""
多线程下载邮件
"""
if not os.path.exists(SAVE_PATH):
os.makedirs(SAVE_PATH)
threads = []
for mailbox in mailbox_list:
conn = imaplib.IMAP4_SSL(IMAP_SERVER)
conn.login(EMAIL_ACCOUNT, EMAIL_PASSWORD)
conn.select(mailbox=mailbox, readonly=True)
status, messages = conn.search(None, 'ALL')
num_emails = len(messages[0].split())
emails_per_thread = num_emails // NUM_THREADS
for i in range(NUM_THREADS):
start = i * emails_per_thread
end = (i + 1) * emails_per_thread if i != NUM_THREADS - 1 else num_emails
t = threading.Thread(target=fetch_emails, args=(mailbox, start, end))
threads.append(t)
t.start()
conn.close()
for t in threads:
t.join()
print('All emails downloaded successfully!')
if __name__ == '__main__':
download_emails()
```
该代码会在当前目录下创建一个名为 `emails` 的文件夹,用于存储下载的邮件。可以根据需要修改 `SAVE_PATH` 变量来指定存储路径。
