以下内容位于文件中.我使用shell脚本调用python脚本.此python脚本发送邮件.但是在邮件内容中,我看到如下所示的输出.它们全部在一行中..我在做什么错

这是sm.py
import logging
import smtplib
import sys
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart
try:
smaid = qs[0].id
gmailUser = 'no-reply@xxxxxxxxxxx.com'
gmailPassword = '12345'
mailServer = smtplib.SMTP('smtp.gmail.com', 587)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(gmailUser, gmailPassword)
to_addr = "xxxxx@xx.com"
subject = sys.argv[1]
body = sys.argv[2]
try:
msg = MIMEMultipart()
msg['From'] = gmailUser
msg['To'] = to_addr
msg["Content-type"] = "text/html"
sub = subject
msg['Subject'] = sub
body = body
msg.attach(MIMEText(body, 'html'))
mailServer.sendmail(gmailUser, to_addr, msg.as_string())
except:
write_exception("send exception")
mailServer.close()
except:
write_exception("send exception1")
解决方法:
如果您坚持发送HTML,则需要HTML换行符：
import cgi
# escape special HTML characters
body = cgi.escape(body)
# use HTML line breaks
body = body.replace("\r\n", "\n").replace("\n", "<br />\n")
但是可能您既不需要Multipart也不需要HTML,因此可以只使用smtplib.SMTP.sendmail：
headers = (('From', gmailUser),
('To', to_addr),
('Subject', subject))
# normalize newlines to CR+LF, as required by SMTP
body = body.replace("\r\n", "\n").replace("\n", "\r\n")
msg = '\r\n'.join("%s: %s" % kv for kv in headers) + '\r\n'*2 + body
mailServer.sendmail(gmailUser, [to_addr], msg)
同样,您不应通过命令行提供文件内容,因为命令行是受长度限制的.相反,您应该通过STDIN提供文件,例如python …< /tmp/alert.txt并通过阅读
import sys
body = sys.stdin.read()
