password = "my mailtrap pass"
sender = "[e-mail]"
receiver = "[e-mail]"
def randomString(stringLength=10):
letters = string.ascii_lowercase
return ''.join(random.choice(letters) for i in range(stringLength))
def randomMessage():
random_string1 = randomString()
random_string2 = randomString()
message = f"""
Subject: {random_string1}
To: {receiver}
From: {sender}

问题出在消息类型上。我把它改成了MIMEText，它现在可以工作了。

import random
import string
import smtplib
from email.mime.text import MIMEText
port = 2525 
smtp_server = "smtp.mailtrap.io"
login = "my mailtrap login"
password = "my mailtrap pass"
sender = "[e-mail]"
receiver = "[e-mail]"
def randomString(stringLength=10):
lettersDigits = string.ascii_lowercase + "0123456789"
return ''.join(random.choice(lettersDigits) for i in range(stringLength))
def makeMessage(subject, content):
message = MIMEText(content)
message["Subject"] = subject
message["From"] = sender
message["To"] = receiver
return message
def randomMessage():
return makeMessage(randomString(), randomString())
def sendMessage(message):
with smtplib.SMTP(smtp_server, port) as server:
server.login(login, password)
server.sendmail(sender, receiver, message.as_string())
