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")

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")

但可能您既不需要Multipart也不需要HTML,因此您只需使用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)

此外,您不应通过命令行提供文件内容,因为命令行是长度限制的。相反,你应该通过STDIN提供文件,就像在python ... < /tmp/alert.txt中一样,并通过

读取
import sys
body = sys.stdin.read()

text/plain而不是text/html发送。 你那里没有任何HTML。 这应该解决它,因为它取决于客户端正确显示文本。新行在HTML中的效果不同。

答案 2 :(得分:0)

您将邮件的内容类型设置为“text / html”,因此用户的邮件代理显然会将主体解释并呈现为html。如果要保留纯文本格式,请不要将内容类型设置为text / html。

您使用的是哪个shell?

"`cat xxx`" 
csh中的

将删除所有换行符并返回空格分隔的字符串

> cat >testfile
line 1
line 2
<ctrl-d>
> echo "`cat testfile`"
line 1 line 2
