我需要弄清楚如何制作一个脚本来扫描目录中的新文件，并在有新文件时通过电子邮件发送文件。
有人不断在我的公寓楼偷自行车！首先是我的错（我必须锁住它），现在骗子通过切断链条升级了。骗子剪断 1/2 英寸的飞机电线偷走了我的第二辆自行车后，我得到了它。
无论如何，使用树莓派作为运动激活的安全摄像头，我希望它在视频程序完成录制后立即向我发送视频文件。这是为了防止他们偷走圆周率。
我正在查看这些示例，但我不知道如何使脚本连续运行（每分钟）或如何使其扫描文件夹中的新文件。
好的 我把它归结为扫描然后尝试发送电子邮件。尝试附加视频文件时失败。你能帮忙吗？这是修改后的代码：
失败的是：
msg = MIMEMultipart()
类型错误：“LazyImporter”对象不可调用，第 38 行

我终于成功了。我必须使用 python 2.5 来消除 LazyImporter 错误。每次将新文件添加到安全文件夹时，它都会通过电子邮件发送给我。日志记录已损坏。

看起来电子邮件模块已经随着时间的推移而被重构。这修复了我在 Python 2.7 上的
'LazyImporter' object not callablefrom email.mime.text import MIMEText
值得注意的是，它对（我所认为的）像
import email; email.mime.text.MIMEText(...)我使用 python3，我一生都无法让这些示例中的任何一个发挥作用，但我能够想出一些有效且简单得多的东西。
import smtplib
from email.message import EmailMessage
from email.mime.base import MIMEBase
from email import encoders
# Defining Objects and Importing Files ------------------------------------
# Initializing video object
video_file = MIMEBase('application', "octet-stream")
# Importing video file
video_file.set_payload(open('video.mkv', "rb").read())
# Encoding video for attaching to the email
encoders.encode_base64(video_file)
# creating EmailMessage object
msg = EmailMessage()
# Loading message information ---------------------------------------------
msg['From'] = "[email protected]"
msg['To'] = "[email protected]"
msg['Subject'] = 'text for the subject line'
msg.set_content('text that will be in the email body.')
msg.add_attachment(video_file, filename="video.mkv")
# Start SMTP Server and sending the email ---------------------------------
server=smtplib.SMTP_SSL('smtp.gmail.com',465)
server.login("[email protected]", "some-clever-password")
server.send_message(msg)
server.quit()
只需将脚本放入循环中并让它休眠 60 秒。您可以使用
globinimport time, glob
files=glob.glob("/home/me/Desktop/*.mp4") #Put whatever path and file format you're using in there.
while 1:
new_files=glob.glob("/home/me/Desktop/*.mp4")
if len(new_files)>len(files):
for x in new_files:
if x not in files:
print("New file: "+x) #This is where you would email it. Let me know if you need help figuring that out.
files=new_files
time.sleep(60)
@Dewey Brooke 代码很好，需要额外一行。
我的代码与他添加的代码有点不同，比如时间是可选的。
我刚刚开始工作，所以有一个问题。当你打开gmail时，有两个文件。我稍后会解决这个问题
import cv2
import smtplib
from time import sleep
from email import encoders
from email.mime.base import MIMEBase
from email.message import EmailMessage
VIDEOFILE='example.mp4'
TO='[email protected]'
FROM='[email protected]'
subject='Greetings'
body='Camera photo'
Pass='App_pass'#App password from google gmail
vidFile=MIMEBase('application','octect-stream')
vidFile.set_payload(open(VIDEO,'rb').read())
encoders.encode_base64(vidFile)vidFile.add_header('Content-Disposition','attachment; filename={}'.format(example.mp4'))
msg=EmailMessage()
msg["To"]=TO
msg["From"]=FROM
msg["Subject"]=subject
msg.set_content('Video From Cam')
msg.add_attachment(vidFile,filename='VIDEOFILE')
final_message=msg.as_string()
s=smtplib.SMTP('smtp.gmail.com',587)
s.set_debuglevel(1)
s.ehlo()
s.starttls()
s.login(FROM,Pass)
s.sendmail(FROM,TO,final_message)
sleep(1)
s.quit()
print('\nMessage Sent')
