如何将 CP1252 文本文件转换为 Ascii 以便使用 Python 导出电子邮件?

Question

我已经抓取了几个网站并将输出整合到一个文本文件中。当我尝试将该文件放入SMTPLib电子邮件链时，出现编码错误：

", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 156: invalid start byte

这是我的代码。据我所知，该文本文件中没有任何特别之处：

import requests, os, smtplib, codecs
from bs4 import BeautifulSoup
from email.mime.text import MIMEText

homeworkResults = open('homeworkResults.txt','r', encoding= 'utf-8')
homeworkContent = homeworkResults.read()
#homeworkContent.encode()
homeworkResults.close()
print("attempting email...")
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login('[e-mail]','Password')
smtpObj.sendmail('[e-mail]' , '[e-mail]','Subject: Kids Homework Updatenn ' + homeworkContent) 
smtpObj.quit()

Answer 1

它在我在open函数之前添加codes.后工作。

此代码还通过使用ignore参数忽略解码错误：通过将errors参数设置为ignore或replace，可以使codecs.open()忽略文件中的解码错误。默认情况下，它设置为strict。

import requests, os, smtplib, codecs
from bs4 import BeautifulSoup
from email.mime.text import MIMEText

homeworkResults = codecs.open('homeworkResults.txt','r', encoding= 'utf-8', errors='ignore')
homeworkContent = homeworkResults.read()
#homeworkContent.encode()
homeworkResults.close()
print("attempting email...")
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login('[e-mail]','Password')
smtpObj.sendmail('[e-mail]' , '[e-mail]','Subject: Kids Homework Updatenn ' + homeworkContent) 
smtpObj.quit()
