Python  发送 SMTP 邮件

python 的 smtplib 模块对 smtp 协议进行了简单的封装，可以用于发送 smtp 协议的电子邮件；

发送普通邮件

 

import smtplib

from email.header import Header

from email.mime.text import MIMEText

​

# 使用 163 邮箱的 SMTP 服务

mail_host = "smtp.163.com"              # smtp 服务器

mail_user = "[email protected]"  # smtp 服务器验证用户名

mail_password = "*************"         # smtp 服务器验证密码(smtp 授权码)

​

sender = "[email protected]"          # 发送地址

receivers = ["[email protected]"]   # 接收地址

​

# 信息对象（dict 对象）

message = MIMEText("Hello world", "plain", "utf-8")

message["From"] = Header("assad", "utf-8")

message["To"] = Header("Mr.lin", "utf-8")

message["Subject"] = Header("python smtp 邮件测试", "utf-8")

​

​

try:

    server = smtplib.SMTP()                  # 创建 SMTP 对象

    server.connect(mail_host, 25)            # 连接 smtp 服务器，默认端口25

    server.login(mail_user, mail_password)   # 登陆 smtp 服务器

    server.sendmail(sender, receivers, message.as_string())   # 发送邮件

    print("send email success")

except smtplib.SMTPException as err:

    print("send email fail")

    print("Error message:", err)

发送 HTML 文本邮件

 

import smtplib

from email.header import Header

from email.mime.text import MIMEText

​

# 使用 163 邮箱的 SMTP 服务

mail_host = "smtp.163.com"              # smtp 服务器

mail_user = "[email protected]"  # smtp 服务器验证用户名

mail_password = "*************"         # smtp 服务器验证密码(smtp 授权码)

​

sender = "[email protected]"          # 发送地址

receiver = "[email protected]"   # 接收地址

​

mail_msg = """

Hello World!

this is a test email from python smtp

"""

​

# 信息对象（dict 对象）

message = MIMEText(mail_msg, "html", "utf-8")

message["From"] = Header(sender, "utf-8")

message["To"] = Header(receiver, "utf-8")

message["Subject"] = Header("python smtp html 邮件测试", "utf-8")

​

​

try:

    server = smtplib.SMTP()                  # 创建 SMTP 对象

    server.connect(mail_host, 25)            # 连接 smtp 服务器，默认端口25

    server.login(mail_user, mail_password)   # 登陆 smtp 服务器

    server.sendmail(sender, receiver, message.as_string())   # 发送邮件

    print("send email success")

except smtplib.SMTPException as err:

    print("send email fail")

    print("Error message:", err)

发送带有附件的邮件

 

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

from email.header import Header

​

# 使用 163 邮箱的 SMTP 服务

mail_host = "smtp.163.com"              

mail_user = "[email protected]" 

mail_password = "*************"        

​

sender = "[email protected]"   

receiver = "[email protected]" 

# 邮件信息对象

message = MIMEMultipart()

message['From'] = Header(sender, 'utf-8')

message['To'] =  Header(receiver, 'utf-8')

message['Subject'] = Header('python smtp 邮件附件测试', 'utf-8')

# 邮件正文内容

message.attach(MIMEText('this is a test email from python smtp', 'plain', 'utf-8'))

# 附件1：当前目录下的 test1.txt 文件

att1 = MIMEText(open('test1.txt', 'rb').read(), 'base64', 'utf-8')

att1["Content-Type"] = 'application/octet-stream'

att1["Content-Disposition"] = 'attachment; filename="test1.txt"'

​

# 附件2：当前目录下的 test2.txt 文件

att2 = MIMEText(open('test2.txt', 'rb').read(), 'base64', 'utf-8')

att2["Content-Type"] = 'application/octet-stream'

att2["Content-Disposition"] = 'attachment; filename="test2.txt"'

​

# 向邮件对象添加附件对象

message.attach(att1)

message.attach(att2)

try:

    server = smtplib.SMTP()                 

    server.connect(mail_host, 25)            

    server.login(mail_user, mail_password)  

    server.sendmail(sender, receiver, message.as_string())   

    print("send email success")

except smtplib.SMTPException as err:

    print("send email fail")

    print("Error message:", err)
