我有一個用 python 編寫的安全程序。它檢測何時有人在相機前（機器學習）并向所有者發送一封帶有入侵者照片的電子郵件。我的問題是如何線程化電子郵件功能，因為我想在程序發現入侵者時發送照片。現在，如果它發現入侵者，則執行將停止，直到通過電子郵件發送照片。我嘗試使用線程模塊，但它不起作用（我沒有 python 線程的經驗）。我只能啟動一個線程，但我不知道如何讓它用同一個線程發送多張照片。（不創建更多線程）。def send_mail(path): sender = 'MAIL' gmail_password = 'PASS' recipients = ['OWNER']# Create the enclosing (outer) message outer = MIMEMultipart() outer['Subject'] = 'Threat' outer['To'] = COMMASPACE.join(recipients) outer['From'] = sender outer.preamble = 'Problem.\n'# List of attachments attachments = [path]# Add the attachments to the message for file in attachments: try: with open(file, 'rb') as fp: msg = MIMEBase('application', "octet-stream") msg.set_payload(fp.read()) encoders.encode_base64(msg) msg.add_header('Content-Disposition', 'attachment', filename=os.path.basename(file)) outer.attach(msg) except: print("Unable to open one of the attachments. Error: ", sys.exc_info()[0]) raise composed = outer.as_string()# Send the email try: with smtplib.SMTP('smtp.gmail.com', 587) as s: s.ehlo() s.starttls() s.ehlo() s.login(sender, gmail_password) s.sendmail(sender, recipients, composed) s.close() print("Email sent!") except: print("Unable to send the email. Error: ", sys.exc_info()[0]) raise

我想您會想要在線程已經發送時更新要發送的照片（不運行帶有要發送的目標照片的線程），因此您可以將要發送的照片存儲在全局變量中。這是我解決這個問題的方法：
from threading import Thread
import time
def send_email():
print('started thread')
global photos_to_send
while len(photos_to_send) > 0:
current_photo = photos_to_send.pop(0)
print('sending {}'.format(current_photo))
time.sleep(2)
print('{} sent'.format(current_photo))
print('no more photos to send ending thread')
photos_to_send = ['photo1.png']
thread1 = Thread(target=send_email, args=())
thread1.start()
photos_to_send.append('photo2.png')
thread1.join()
#started thread
#sending photo1.png
#photo1.png sent
#sending photo2.png
#photo2.png sent
#no more photos to send, ending thread
