一丶设置QQ邮箱
网址：mail.qq.com/
使用自己的QQ账号密码登录到QQ邮箱，点击设置，然后选择账户，
将这些服务开启，然后选择“生成授权码”，
按照提示，发送完短信后就可以得到授权码了，我们可以用这个授权码作为密码第三方登录QQ邮箱，
二丶Python程序发送邮件
# -*- coding: utf-8 -*-import smtplibfrom email.mime.image import MIMEImagefrom email.mime.text import MIMETextfrom email.utils import formataddrfrom email.mime.multipart import MIMEMultipartsender = 'xxxx@' # 发送者邮箱password = 'xxxxxxxxxxxxxxxx' # 授权码user = 'xxxx@' # 接收者邮箱def mail():ret = Truetry:"""msg = MIMEText("This is liujian's first SMTP program", 'plain', 'utf-8')msg['From'] = formataddr(["我是巴伯你是谁", sender])msg['To'] = formataddr(["LJ", user])msg['Subject'] = "发送邮件测试""""msg = MIMEMultipart()msg['From'] = formataddr(["我是巴伯你是谁", sender])msg['To'] = formataddr(["LJ", user])msg['Subject'] = "Python发送邮件测试"msg.attach(MIMEText('这是我的第二个Python邮件程序', 'plain', 'utf-8'))att1 = MIMEText(open('text.txt', 'rb').read(), 'base64', 'utf-8') # 添加附件att1["Content-Type"] = 'application/octet-stream'att1["Content-Disposition"] = 'attachment; filename="text.txt"'msg.attach(att1)msgPicture = MIMEMultipart()msg.attach(msgPicture) # 添加图片mail_msg = """<p>Python 邮件发送测试...</p><p><a href="">百度搜索</a></p><p><img src="cid:image1"></p>"""msgPicture.attach(MIMEText(mail_msg, 'html', 'utf-8')) # 添加网址fp = open('test.png', 'rb')msgImage = MIMEImage(fp.read())fp.close()msgImage.add_header('Content-ID', '<image1>') # 定义图片id，在html中引用msg.attach(msgImage)server = smtplib.SMTP_SSL("", 465) # smtp服务器地址和端口号server.login(sender, password)server.sendmail(sender, [user, ], msg.as_string())server.quit()except Exception:ret = Falsereturn retret = mail()if ret:print ("发送邮件成功")else:print ("发送邮件失败")
上述历程发送了一封带有文档附件，图片和网址链接的邮件，收到的邮件内容如下：
