版上有沒有python的高手呢?
 

最近在學習python , 萬事起頭難..

#! /usr/bin/env Python
#!coding=utf-8
import smtplib
import random
import dns.resolver
answers = dns.resolver.query('yahoo.com.tw', 'MX')
host = "0"
newhost = "0"
port = "25"
for rdata in answers:
host = (rdata.exchange)
print host
if host != "0":
break
#print host
#print 'Host', rdata.exchange, 'has preference', rdata.preference
smtp=smtplib.SMTP()
smtp.connect(host, port)

這個是取得domain mx 的一段, print host 是正確的, (mx-tw.mail.gm0.yahoodns.net.)
但在 len(host)時得到的是 6, 似乎變成陣列了.

所以在smtp.connect(host, port) 給的值就不對.
應該要怎麼處理呢?

剛試了一下

host = (rdata.exchange) 取回來的值本身就是陣列
host[0] = mx-tw
host[1] = mail
host[2] = gm0
host[3] = yahoodns
host[4] = net
host[5] =
所以len(host) = 6 是正確的

print host 時, 能正常顯示，
大概是因為print會自動隱式轉換為文字型態

若直接取得host的值
你可以這樣用
host.to_text() 或 str(host)

謝謝, 這樣子試真的就正確了. 可否再請教一個問題呢? 也是Google 了一段時間了.
smtp.sendmail(FROM,[TO],body)
smtp.getreply()
這個是取得反回值, email 是否發送成功之類的.
但這樣子寫法, 似乎在 sendmail 後就自動關閉connect 了, 所以無法取得.
如果用smtp.docmd 去一步一步 可以使用 getreply() 但取回的值要怎麼判斷?
h = smtp.getreply() ???

另, 去看了一下 smtplib.cy 裡 sendmail 本身好像就有丟回錯誤碼的功能.
請教一下要怎麼取得呢?

用try
我之前學的時候，從某處抄來的

try:
Mail=smtplib.SMTP()
Mail.connect(mail_host)
Mail.login(mail_user,mail_pw)
Mail.sendmail(FROM,[TO],body)
Mail.close()
return True
except Exception, e:
print str(e)
return False

謝謝關鍵字, 套用後

try:
smtp.ehlo()
smtp.sendmail(From_Email,To_Email,body)
MailReplyDesc="Successfully sent email!!"
Err_Type = "0"
except smtplib.socket.gaierror:
MailReplyDesc="Couldn't contact the host!!"
Err_Type = "1"
except smtplib.SMTPAuthenticationError:
MailReplyDesc="Login failed!!"
Err_Type = "2"
這樣子就順利處理許多錯誤了..

程式整個套起來了. 包含從SQL 拉相關資料, 兜字串, 送出, 回寫SQL 值.

但發生個問題.. 在
NOWBODY = MIMEText((row.ePaper_Content), _subtype='html', _charset='UTF-8')
....
body=string.join((
"From:%s <%s>" % (From_Name,From_Email),
"To:%s" % To_Email,
"Subject: %s" % Subject,
"",NOWBODY),
"\r\n")
NOWBODY 從資料庫撈出來時是 html語法
會無法成功把字串合併, 試過許多不同方法.
body.replace(body,"") 去替換, 或是使用 body.attech(NOWBODY)
要嘛就是合併失敗, 要嘛就是忠實呈現(就是變純文字啦..)

跟您再請教一下.

http://stackoverflow.com/questions/...file-via-python

參考上面, 應該有你要的答案.

還是在重覆的地方打轉..快暈頭了 .. 我把程式碼貼上來好了 請高手看一下 謝謝

錯在 smtp.sendmail(From_Email,To_Email,body) 這一段.
NOWBODY 內容是標準的HTML語法.簡單的TEST 錯誤訊息是
TypeError: Type unicode connot be serialized.

TypeError: Type unicode connot be serialized.

應該是說你必須把要serialize的文字(我猜是要寄送的郵件內容)進行編碼,例如:

unicodeMailBody.encode('utf8')

把文字內容以UTF-8方式編碼.

smtp.quit()#退出

現在的情況是, 可以正常寄送html Email , 但中文會有問題.
會出現.UnicodeEncodeError : ascii code can't encode charactrt u \u6211
google 是編碼問題. 但在嘗試 NOWBODY 讀進來時 .encode('utf8') 不行
或是在body 兜字串時.encode('utf8') 也不行, 再
再請教一下, 請問是哪地方需要再修正呢?

讀進來時應該是先decode,要送出時encode.

你的信件內文是來自於資料庫查詢的結果嗎?如果你的信件內容在存入資料庫時是用big5編碼的字串,那麼你讀出來就要先解碼:

content = content.decode('big5')

還原成unicode字串.然後在寄出前編碼成utf8(或者你希望的編碼方式).
