python - 用Python发送电子邮件

Question

我正在尝试使用 Python 3.3 发送基本电子邮件。我在这里跟踪第一段代码:

https://docs.python.org/3.3/library/email-examples.html

我的代码如下:

def emailCurrentRankings(recipientEmail):
    fp = open('rankings.txt', 'rb')
    msg = MIMEText(fp.read())
    fp.close()

    sender = 'bclayman@gmail.com'
    msg['Subject'] = 'CSA Rankings'
    msg['From'] = sender
    msg['To'] = recipientEmail

    s = smtplib.SMTP('localhost')
    s.sendmail(sender, [recipientEmail], msg.as_string())
    s.quit()

我的主函数像这样调用这个方法:

emailCurrentRankings('bclayman@gmail.com')

我能看出的唯一区别是我在第二行使用“rankings.txt”而不是文本文件。我尝试过两者并收到相同的错误消息:

Traceback (most recent call last):
  File "helpfulFunctions.py", line 128, in <module>
    main()
  File "helpfulFunctions.py", line 120, in main
    emailCurrentRankings('bclayman@gmail.com')
  File "helpfulFunctions.py", line 106, in emailCurrentRankings
    msg = MIMEText(fp.read())
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/email/mime/text.py", line 34, in __init__
    _text.encode('us-ascii')
AttributeError: 'bytes' object has no attribute 'encode'

当我用谷歌搜索时，似乎必须进行一些身份验证(让我能够从给定的电子邮件发送)。但我在其上建模代码的最基本示例并未提及这一点...

有什么想法我会误入歧途吗？

谢谢，BClayman

尝试在不使用二进制格式的情况下打开文件。

也许类似 -

fp = open('rankings.txt', 'r')
