通過python通過gmail發送電子郵件時出錯

Question

你好！

我正在嘗試用Python編寫一個程序，該程序將接收電子郵件地址和命令行參數中的某些短語，並且該程序會將短語（帶有一些背景信息）發送到所提供的電子郵件地址。

該代碼如下：

#Mail Module
try:
    import smtplib
    import sys
    from email.mime.text import MIMEText
except ImportError:
    print "Error importing necessary modules into the project, Please contact MagshiProject staff"
else:
    def sendAnEmail():
        try:
            sender      = "magshiproject@gmail.com"
            recipient   = str(sys.argv[1])
            password    = str(sys.argv[2])
            message     = MIMEText("""From: From Magshimim Project <magshiproject@gmail.com>
                            To: To User <'{0}'>
                            Subject: Your password to further use MagshiProject Program

                            Your password is: '{1}'
                            Please copy and paste it from here to the window requesting this password in order to proceed.
                            This password will not be useful in 24 hours.""".format(recipient, password))

            message['Subject']  = "Your password to use MagshiProject"
            message['From']     = sender
            message['To']       = recipient
            s                   = smtplib.SMTP("smtp.google.com", 587)
            s.ehlo()
            s.starttls()
            s.ehlo()
            s.login("Username", "Password")
            s.sendmail(me, [you], msg.as_string())
            s.quit()
            print "Message has been sent successfully."
        except Exception as e:
            print "Something went wrong, Please try again later."
            print "Error Message: '{0}'.".format(str(e))
            print "Error type: '{0}'.".format(str(type(e)))
    sendAnEmail()

錯誤如下：

Something went wrong, Please try again later.
Error message: '[Errno 11001] getaddrinfo failed'.
Error type: '<class 'socket.gaierror'>'.

我該怎么辦才能解決這個問題？

預先感謝您，Iliya

您的代碼中存在一些問題，似乎表明這有點像復制/粘貼工作，但希望我們可以通過這一過程為您提供幫助。

服務器地址

您會注意到，您已使用以下代碼連接到SMTP服務器

s = smtplib.SMTP("smtp.google.com", 587)

但是，通過Google快速搜索“ Gmail SMTP”，我們可以看到Gmail的所有SMTP設置 ，包括地址： "smtp.gmail.com" 。 所以我們將其更改為

s = smtplib.SMTP("smtp.gmail.com", 587)

錯誤/缺少變量

此外，還有另一個小錯誤

s.sendmail(me, [you], msg.as_string())

顯然， me和[you]未定義，因此根據您的其他變量， me應該是電子郵件的sender ，而[you]應該是recipient ，因此我們將用您現有的變量替換這些值。 您也沒有變量msg ，因此在這種情況下，它可能應該是message.as_string() 。

另外，我們與s.login("Username","Password")一起使用的s.login("Username","Password")可能是發送電子郵件的同一個人，因此我們將其替換為sender 。

所以這是正確形式的代碼

#Mail Module
try:
    import smtplib
    import sys
    from email.mime.text import MIMEText
except ImportError:
    print "Error importing necessary modules into the project, Please contact MagshiProject staff"
else:
    def sendAnEmail():
        try:
            sender      = "magshiproject@gmail.com"
            recipient   = str(sys.argv[1])
            password    = str(sys.argv[2])
            message     = MIMEText("""From: From Magshimim Project <magshiproject@gmail.com>
                            To: To User <'{0}'>
                            Subject: Your password to further use MagshiProject Program

                            Your password is: '{1}'
                            Please copy and paste it from here to the window requesting this password in order to proceed.
                            This password will not be useful in 24 hours.""".format(recipient, password))

            message['Subject']  = "Your password to use MagshiProject"
            message['From']     = sender
            message['To']       = recipient
            s                   = smtplib.SMTP("smtp.gmail.com", 587)
            s.ehlo()
            s.starttls()
            s.ehlo()
            s.login(sender, "Password")
            s.sendmail(sender, recipient, message.as_string())
            s.quit()
            print "Message has been sent successfully."
        except Exception as e:
            print "Something went wrong, Please try again later."
            print "Error Message: '{0}'.".format(str(e))
            print "Error type: '{0}'.".format(str(type(e)))
    sendAnEmail()

假設您將"Username"和"Password"替換為實際值，並使用如下參數調用程序（假設文件名為sendmail.py ），則此方法有效

python sendmail.py "someone@somewhere.com" "password"

編輯：獲取sender密碼

為了使此腳本更加完善，可以使用getpass模塊提示輸入sender密碼。 添加以下導入

import getpass

再改"Password"在s.login(sender, "Password")以

s.login(sender,getpass.getpass("Please enter your password for %s: " % sender))

然后系統會提示您輸入sender的gmail密碼
