Question

对于Raspberry Pi 3，我运行了以下程序，旨在每隔2分钟将相机捕获的新图像发送到Gmail帐户。但是出现了问题。在第一次传输中，发送捕获的图像。在第二次传输中，发送第一图像和新拍摄的图像。在第三次传输中，发送了三个图像。我是Python的新手。有人可以提供一些线索吗？非常感谢您的帮助。

import smtplib
import time 
from email.mime.multipart  import MIMEMultipart
from email.mime.text  import MIMEText 
from email.mime.base  import MIMEBase 
from email.mime.image  import MIMEImage 
from email  import encoders 

from picamera  import PiCamera
camera = PiCamera()
camera.rotation = 180

fromaddr = "jsmith05@yahoo.com.au"
toaddr = "jsmith05@gmail.com"

msg1 = MIMEMultipart()
msg1['From'] = fromaddr
msg1['To'] = toaddr
msg1['Subject'] = "Screenshot of room"

while True:

    camera.start_preview(alpha=200)    
    time.sleep(5)  
    camera.capture('/home/pi/Desktop/image.jpg')  
    camera.stop_preview()

    filename = "room.jpg"    
    attachment = open('../Desktop/image.jpg', "r")    
    part = MIMEBase('application', 'octet-stream')     
    part.set_payload(attachment.read())
    encoders.encode_base64(part)    
    part.add_header('Content-Disposition', "attachment; filename= %s" % filename)

    msg1.attach(part)
    text = msg1.as_string()
    myserver = smtplib.SMTP_SSL('smtp.mail.yahoo.com', 465)    
    myserver.login("jsmith05@yahoo.com.au", "Ch53644")    
    myserver.sendmail(fromaddr, toaddr, text) 
    myserver.close()   

    time.sleep(120)

事实上，您正在一遍又一遍地发送包含更多内容的相同消息。移动它：

msg1 = MIMEMultipart()
msg1['From'] = fromaddr
msg1['To'] = toaddr
msg1['Subject'] = "Screenshot of room"

在while区块，你应该没问题

多个图像循环发送到smtp服务器
