如何使用Python从文件夹中随机发送pdf文件

Question

我正在尝试创建一个电子邮件机器人，它将从文件夹中随机向我发送一个pdf文件。虽然我的代码没有显示任何错误，但我没有收到任何邮件。如果你能告诉我哪里出了问题，我该怎么办，那会很有帮助。谢谢。

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import  MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders
import os
import random
def send():
body = ""
sender_email = "email"
password = "my_password"
receiver_email = "email"
msg = MIMEMultipart()
msg['Subject'] = '[Email Test]'
msg['From'] = sender_email
msg['To'] = receiver_email
msg.attach(MIMEText(body, 'plain'))
path = "C:/Users/Asus/PycharmProjects/messenger_bot/files"
files = os.listdir(path)
index = random.randrange(0, len(files))
print(files[index])
attachment = open(os.path.join(path, random.choice(files)), 'rb')
payload = MIMEBase('application', 'octate-stream')
# payload = MIMEBase('application', 'pdf', Name=pdfname)
payload.set_payload(attachment.read())
# enconding the binary into base64
encoders.encode_base64(payload)
# add header with pdf name
payload.add_header('Content-Decomposition', 'attachment', filename=files)
msg.attach(payload)
# use gmail with port
session = smtplib.SMTP('smtp.gmail.com', 587)
# enable security
session.starttls()
# login with mail_id and password
session.login(sender_email, password)
text = msg.as_string()
session.sendmail(sender_email, receiver_email, text)
session.quit()
print('Mail Sent')

Answer 1

您确定发件人的电子邮件是正确的吗？将sender_ email从"；电子邮件"；到你的实际电子邮件，它应该工作

Answer 2

根据我从官方文档中收集的信息。您遇到的问题是，starttls将一个密钥文件和一个证书文件放在一起，或者单独使用一个上下文，而您没有给出。

尝试添加以下内容：

context = ssl.create_default_context()

然后将starttls((调用更改为

starttls(context=context)
