这是一个使用SMTP API的自定义电子邮件内容的例子：

import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart from email.mime.image import MIMEImage import requests

定义SMTP服务器和端口号

SMTP_SERVER = 'smtp.gmail.com' SMTP_PORT = 587

定义发件人和收件人

FROM_EMAIL = 'your_email@gmail.com' TO_EMAIL = 'recipient_email@gmail.com'

定义SMTP用户名和密码

SMTP_USERNAME = 'your_email@gmail.com' SMTP_PASSWORD = 'your_password'

定义邮件主题和正文

SUBJECT = 'Customized Email Content' BODY_TEXT = 'This is a customized email content.'

定义邮件附件和图片

IMAGE_URL = 'https://example.com/image.jpg' IMAGE_NAME = 'image.jpg' response = requests.get(IMAGE_URL) image_data = response.content image = MIMEImage(image_data) image.add_header('Content-ID', '') attachment = MIMEText(image_data, 'base64', 'utf-8') attachment.add_header('Content-Disposition', 'attachment', filename=IMAGE_NAME)

创建邮件对象并添加附件和图片

msg = MIMEMultipart() msg['From'] = FROM_EMAIL msg['To'] = TO_EMAIL msg['Subject'] = SUBJECT msg.attach(MIMEText(BODY_TEXT)) msg.attach(attachment) msg.attach(image)

创建SMTP客户端并登录

smtp_client = smtplib.SMTP(SMTP_SERVER, SMTP_PORT) smtp_client.starttls() smtp_client.login(SMTP_USERNAME, SMTP_PASSWORD)

发送邮件并退出SMTP客户端

smtp_client.sendmail(FROM_EMAIL, TO_EMAIL, msg.as_string()) smtp_client.quit()

这个例子会发送一个包含自定义正文、图片和附件的电子邮件。您只需要替换变量的值，将其应用于您的应用程序中即可
