  • python3:利用SMTP协议发送QQ邮件+附件

    转载请表明出处:https://www.cnblogs.com/shapeL/p/9115887.html

    1.发送QQ邮件,首先必须知道QQ邮箱的SMTP服务器

    http://service.mail.qq.com/cgi-bin/help?id=28&no=167&subtype=1

    2.发送邮件之前,必须开启qq邮箱的smtp服务

    设置路径:邮箱设置--账户--开启截图服务--保存更改

    3.代码抛出异常分析

    (1)邮箱密码传入值为日常登录密码,报错

    global send_user
    global email_host
    global password
    
    password = 'xxx92'
    email_host = "smtp.qq.com"
    send_user = "11xxx@qq.com"

    抛出异常:

    smtplib.SMTPAuthenticationError:(535, b'Error: xc7xebxcaxb9xd3xc3xcaxdaxc8xa8xc2xebxb5xc7xc2xbcxa1xa3xcfxeaxc7xe9xc7xebxbfxb4: http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256')

    打开抛出异常中的链接:是关于授权码的介绍,根据介绍,登录时应该使用授权码作为登录密码,该处的授权码是开启服务时收到的16位授权码

    http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

    修改代码:

    password = "lunkbrgwqxhfjgxx"(对应的16位授权码)

    (2)安全邮件,需要通过SSL发送

    server = smtplib.SMTP()
    server.connect(email_host,25)

    抛出异常:

    smtplib.SMTPServerDisconnected: Connection unexpectedly closed

    QQ邮箱是支持安全邮件的,需要通过SSL发送的邮件:使用标准的25端口连接SMTP服务器时,使用的是明文传输,发送邮件的整个过程可能会被窃听。要更安全地发送邮件,可以加密SMTP会话,实际上就是先创建SSL安全连接,然后再使用SMTP协议发送邮件

    修改代码:

    server = smtplib.SMTP_SSL()
    server.connect(email_host,465)# 启用SSL发信, 端口一般是465

    4.附上完整代码

    #coding:utf-8
    import smtplib
    from email.mime.text import MIMEText
    
    class SendEmail:
        global send_user
        global email_host
        global password
        password = "lunkbrgwqxhfjgxx"
        email_host = "smtp.qq.com"
        send_user = "11xx@qq.com"
    
        def send_mail(self,user_list,sub,content):
            user = "shape" + "<" + send_user + ">"
            message = MIMEText(content,_subtype='plain',_charset='utf-8')
            message['Subject'] = sub
            message['From'] = user
            message['To'] = ";".join(user_list)
            server = smtplib.SMTP_SSL()
            server.connect(email_host,465)
            server.login(send_user,password)
            server.sendmail(user,user_list,message.as_string())
            server.close()
    
    if __name__ == '__main__':
        send = SendEmail()
        user_list = ['11xx@qq.com']
        sub = "测试邮件"
        content = "ceshi看看"
        send.send_mail(user_list,sub,content)

    (1)Python对SMTP支持有smtplib和email两个模块,email负责构造邮件,smtplib负责发送邮件

    (2)构造MIMEText对象时,第一个参数是邮件正文;第二个参数是MIME的subtype,传入'plain'表示纯文本,最终的MIME就是'text/plain';最后一定要用utf-8编码保证多语言兼容性

    (3)发送的邮件需要添加头部信息,头部信息中包含发送者、接收者、邮件主题等信息:message['From']、message['To']、message['Subject']

    (4)构造完要发送的邮件信息后,通过SMTP发出去:login()方法用来登录SMTP服务器;sendmail()方法就是发邮件,由于可以一次发给多个人,所以传入一个list;邮件正文是一个str,as_string()把MIMEText对象变成str

    (5)SMTP.close() :关闭SMTP服务器连接

    5、发送邮件带附件

    参考代码:

    #coding:utf-8
    import smtplib
    from email.mime.text import MIMEText
    from email.mime.multipart import MIMEMultipart
    
    class SendEmail:
        global send_user
        global email_host
        global password
        password = "lunkbrgwqxhfjgxx"
        email_host = "smtp.qq.com"
        send_user = "xx@qq.com"
    
        def send_mail(self,user_list,sub,content):
            user = "shape" + "<" + send_user + ">"
    
            # 创建一个带附件的实例
            message = MIMEMultipart()
            message['Subject'] = sub
            message['From'] = user
            message['To'] = ";".join(user_list)
    
            # 邮件正文内容
            message.attach(MIMEText(content, 'plain', 'utf-8'))
    
            # 构造附件(附件为txt格式的文本)
            att = MIMEText(open('../log/log.txt', 'rb').read(), 'base64', 'utf-8')
            att["Content-Type"] = 'application/octet-stream'
            att["Content-Disposition"] = 'attachment; filename="Log.txt"'
            message.attach(att)
    
            server = smtplib.SMTP_SSL()
            server.connect(email_host,465)# 启用SSL发信, 端口一般是465
            # server.set_debuglevel(1)# 打印出和SMTP服务器交互的所有信息
            server.login(send_user,password)
            server.sendmail(user,user_list,message.as_string())
            server.close()
    
        def send_main(self,pass_list,fail_list,no_run_list):
            pass_num = len(pass_list)
            fail_num = len(fail_list)
            #未执行的用例
            no_run_num = len(no_run_list)
            count_num = pass_num + fail_num + no_run_num
    
            #成功率、失败率
            '''
            用%对字符串进行格式化
            %d 格式化整数
            %f 格式化小数;想保留两位小数,需要在f前面加上条件:%.2f;用%%来表示一个%
            如果你不太确定应该用什么,%s永远起作用,它会把任何数据类型转换为字符串 
           '''
            pass_result = "%.2f%%" % (pass_num/count_num*100)
            fail_result = "%.2f%%" % (fail_num/count_num*100)
            no_run_result = "%.2f%%" % (no_run_num/count_num*100)
    
            user_list = ['xx@qq.com']
            sub = "接口自动化测试报告"
            content = "总共执行接口个数%s个,通过个数%s个,失败个数%s个,未执行个数%s个:通过率为%s,失败率为%s,未执行率为%s" % (count_num,pass_num,fail_num,no_run_num,pass_result,fail_result,no_run_result)
            self.send_mail(user_list,sub,content)
