汇总Python发邮件的15个常用方式(附代码)

在Python中，发送电子邮件的方法有很多，以下是15种常见的方法：

1. 使用内置的smtplib模块

import smtplib
 
def send_email(to, subject, body):
    email_user = 'youremail@gmail.com'
    email_password = 'your_password'
    sender_email = 'youremail@gmail.com'
    receiver_email = to
 
    message = f"Subject: {subject}\n\n{body}"
 
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(email_user, email_password)
    server.sendmail(sender_email, receiver_email, message)
    server.quit()
 
send_email('test@test.com', 'Test Subject', 'Test Body')

2. 使用内置的smtplib模块和ssl

import smtplib
import ssl
 
def send_email(to, subject, body):
    email_user = 'youremail@gmail.com'
    email_password = 'your_password'
    sender_email = 'youremail@gmail.com'
    receiver_email = to
 
    message = f"Subject: {subject}\n\n{body}"
 
    context = ssl.create_default_context()
    with smtplib.SMTP_SSL('smtp.gmail.com', 465, context=context) as server:
        server.login(email_user, email_password)
        server.sendmail(sender_email, receiver_email, message)
 
send_email('test@test.com', 'Test Subject', 'Test Body')

3. 使用内置的smtplib模块和starttls

import smtplib
 
def send_email(to, subject, body):
    email_user = 'youremail@gmail.com'
    email_password = 'your_password'
    sender_email = 'youremail@gmail.com'
    receiver_email = to
 
    message = f"Subject: {subject}\n\n{body}"
 
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(email_user, email_password)
    server.sendmail(sender_email, receiver_email, message)
    server.quit()
 
send_email('test@test.com', 'Test Subject', 'Test Body')

4. 使用内置的smtplib模块和ssl.create\_default\_context

import smtplib
import ssl
 
def send_email(to, subject, body):
    email_user = 'youremail@gmail.com'
    email_password = 'your_password'
    sender_email = 'youremail@gmail.com'
    receiver_email = to
 
    message = f"Subject: {subject}\n\n{body}"
 
    context = ssl.create_default_contex
