python 自动发送邮件 python库自带的两个模块，email和smtplib模块，直接import就能用 smtplib：主要用于连接邮箱服务器，登录邮箱，发送邮件（指定发件人，收件人，内容） email：主要用于构建邮件内容（文本、html、图片文件附件等） 1.smtplib # 普通连接，明文传输 smtp = smtplib.SMTP(‘email_server‘, port) # SSL加密，用于QQ等邮件发送 smtp = smtplib.SMTP_SSL(‘email_server‘, port) smtp.login(‘username‘, ‘password‘) # receiver可以是一个列表；msg.as_string()是email模块所构建的内容 smtp.sendmail(‘sender‘, ‘receiver‘, msg.as_string()) # 结束回话 smtp.quit() 1 2 3 4 5 6 7 8 9 邮箱开启smtp服务才能成功连接，普通连接端口是25，SSL加密连接端口是其他，如下图 注意：这里的password并非邮箱密码，而是开启smtp服务后的授权码 2.email 常用的模块有：MIMEText，MIMEImage，MIMEMultipart 2.1 MIMEText 纯文本 # 构造文字内容 text = "this is a test" text_plain = MIMEText(text, ‘plain‘, ‘utf-8‘) 1 2 3 超文本 # html html = """ <html> <body> <h1>this is a test,don‘t scared!</h1> <a href = ‘https://www.baidu.com‘>click it plz!</a> </body> </html> """ msg_html = MIMEText(html, ‘html‘, ‘utf-8‘) 1 2 3 4 5 6 7 8 9 10 11 文件附件 file = open(u‘数字权利激活.rar‘,‘rb‘).read() msg_file = MIMEText(file,‘base64‘,‘utf-8‘) msg_file[‘Content-Disposition‘] = "attachment;filename=‘数字权利激活.rar‘" msg_file[‘Content-Type‘] = ‘application/otcet-stream‘ 1 2 3 4 2.2 MIMEImage photo_file = open(rage your dream.jpg‘, ‘rb‘).read() msg_image = MIMEImage(photo_file) msg_image[‘Content-Disposition‘] = "attachment;filename=‘rage your dream.jpg‘" 1 2 3 2.3 MIMEMultipart 常见的multipart类型有三种：multipart/alternative,multipart/related和multipart/mixed。 邮件类型为"multipart/alternative"的邮件包括纯文本正文（text/plain）和超文本正文（text/html）。 邮件类型为"multipart/related"的邮件正文中包括图片，声音等内嵌资源。 邮件类型为"multipart/mixed"的邮件包含附件。向上兼容，如果一个邮件有纯文本正文，超文本正文，内嵌资源，附件，则选择mixed类型。 #我们一般用 msg = MIMEMultipart(‘mixed’) 1 2 我们必须把Subject，From，To，Date添加到MIMEText对象或者MIMEMultipart对象中，邮件中才会显示主题，发件人，收件人，时间（若无时间，就默认一般为当前时间，该值一般不设置）。 sender = ‘xxxx@qq.com‘ password = ‘ddlwzfotwvtwbeeg‘ fromer = ‘xx<xxx@qq.com>‘ subject = u‘这只是一个测试‘ receiver = [‘xxx@qq.com‘] server = ‘smtp.qq.com‘ port = 465 msg = MIMEMultipart(‘mixed‘) msg[‘Subject‘] = subject msg[‘To‘] = ‘;‘.join(receiver) msg[‘From‘] = fromer msg[‘Date‘] = ‘2019-2-20‘ 1 2 3 4 5 6 7 8 9 10 11 12 说明： msg.add_header(_name,_value,**_params):添加邮件头字段。 msg.as_string():是将msg(MIMEText对象或者MIMEMultipart对象)变为str,如果只有一个html超文本正文或者plain普通文本正文的话，一般msg的类型可以是MIMEText；如果是多个的话，就都添加到MIMEMultipart，msg类型就变为MIMEMultipart。 msg.attach(MIMEText对象或MIMEImage对象):将MIMEText对象或MIMEImage对象添加到MIMEMultipart对象中。MIMEMultipart对象代表邮件本身，MIMEText对象或MIMEImage对象代表邮件正文。 以上的构造的文本，超文本，附件，图片都何以添加到MIMEMultipart(‘mixed’)中： msg.attach(msg_plain) msg.attach(msg_html) msg.attach(msg_file) msg.attach(msg_image) 1 2 3 4 附完整代码: # coding: utf-8 # @Time : 2019/2/19 19:58 # @Author : lsn # @Email : lishuning@huawei.com # @File : emali_auto_send.py # @Software: PyCharm # function : 自动发送邮件，文本图片附件 from email.mime.text import MIMEText from email.mime.image import MIMEImage from email.mime.multipart import MIMEMultipart import smtplib if __name__ == ‘__main__‘: username = ‘xxxx@qq.com‘ password = ‘ddlwzfotwvtwbeeg‘ fromer = ‘xx<xxx@qq.com>‘ subject = u‘这只是一个测试‘ receiver = [‘xxx@qq.com‘] server = ‘smtp.qq.com‘ port = 465 msg = MIMEMultipart(‘mixed‘) msg[‘Subject‘] = subject msg[‘To‘] = ‘;‘.join(receiver) msg[‘From‘] = fromer msg[‘Date‘] = ‘2019-2-20‘ # html html = """ <html> <body> <h1>this is a test,don‘t scared!</h1> <a href = ‘https://www.baidu.com‘>click it plz!</a> </body> </html> """ msg_html = MIMEText(html, ‘html‘, ‘utf-8‘) msg.attach(msg_html) # 图片 photo_file = open(‘rage panda.jpg‘, ‘rb‘).read() msg_image = MIMEImage(photo_file) msg_image[‘Content-Disposition‘] = "attachment;filename=‘rage your dream.jpg‘" msg.attach(msg_image) # file 文件 file = open(u‘数字权利激活.rar‘,‘rb‘).read() msg_file = MIMEText(file,‘base64‘,‘utf-8‘) msg_file[‘Content-Disposition‘] = "attachment;filename=‘数字权利激活.rar‘" msg_file[‘Content-Type‘] = ‘application/otcet-stream‘ msg.attach(msg_file) # 普通连接，明文传输 # smtp = smtplib.SMTP(server, port) # SSL加密，用于QQ等邮件发送 smtp = smtplib.SMTP_SSL(server, port) smtp.login(username, password) # receiver可以是一个列表；msg.as_string()是email模块所构建的内容 smtp.sendmail(username, receiver, msg.as_string()) # 结束回话 smtp.quit() pass
