python使用imap-tools模塊下載郵件中的附件的示例

from imap_tools import MailBox

with MailBox("imap服務器名").login("賬號", "密碼") as mailbox:
    for msg in mailbox.fetch(limit=2,reverse=True):  # 我這裡為瞭避免讀取全部的郵件,加上瞭limit=2的匹配參數,讀取兩封郵件,按照最新接收的次序排序,進行測試; 
        for att in msg.attachments:  # msg為上一行取得的全部郵件
            if att.filename:    # 如果附件的文件名不為空
                att_data = att.payload # 獲得附件的內容
                f = open(att.filename,'wb') # 用二進制打開,一般郵件附件都是二進制的.
                f.write(att_data)
                f.close()
