Python3 pop3取件

困難點

部分郵箱提示密碼錯誤

-ERR Unable to log on

反饋密碼錯誤，但實際上密碼是正確的，該種情況，需要使用授權(quán)碼，而非密碼

目前已知需要授權(quán)碼的郵箱列表

• 騰訊 @qq.com
• 網(wǎng)易 @163.com

Date時間解析

查詢相關(guān)資料，得知可使用email.utils針對郵箱的時間格式進(jìn)行解析

Date: Sat, 15 Jan 2022 14:08:55 +0800

from email.utils import parsedate
import time
date="Sat, 15 Jan 2022 14:08:55 +0800"
print(time.strftime("%Y-%m-%d %H:%M:%S", parsedate(date)))

163郵箱在長時間運(yùn)行后報錯

報錯內(nèi)容

-ERR \xc4\xfa\xb5\xc4\xd5\xca\xba\xc5\xd4\xdd\xca\xb1\xb2\xbb\xbf\xc9\xd3\xc3.\xbf\xc9\xc4\xdc\xb5\xc4\xd4\xad\xd2\xf2\xca\xc7:\xc4\xfa\xb5\xc4\xd5\xca\xba\xc5\xb6\xe0\xb4\xce\xb3\xa2\xca\xd4\xb4\xed\xce\xf3\xb5\xc4\xc3\xdc\xc2\xeb,\xb3\xf6\xd3\xda\xb0\xb2\xc8\xab\xbf\xbc\xc2\xc7,\xce\xd2\xc3\xc7\xc1\xd9\xca\xb1\xcf\xde\xd6\xc6\xc1\xcb\xc4\xfa\xb5\xc4\xd5\xca\xba\xc5\xb5\xc4pop\xb7\xc3\xce\xca\xc8\xa8\xcf\xde

嘗試復(fù)現(xiàn)：

• 長時間運(yùn)行出現(xiàn)
• 在停止運(yùn)行半小時后恢復(fù)
  通過以上觀測得知，可猜測為頻繁請求導(dǎo)致【取件間隔5秒】，延長后可解決
