python3使用SMTP发送邮件

环境：python3 ,IDE : pycharm

非常奇怪的是，用163发送邮件，如果电脑连校园网发送，会被当成垃圾邮件拒绝

如果用手机开热点就可以正常发送

代码如下

#!/usr/bin/python
# -*- coding: utf-8 -*-
import time
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

# 第三方 SMTP 服务
mail_host = ""      # SMTP服务器a
mail_user = ""                  # 用户名
mail_pass = ""               # 授权密码，非登录密码

sender = ''    # 发件人邮箱(最好写全, 不然会失败)
receivers = ['']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

title = '163邮件测试'  # 邮件主题
content = '我用Python'

def sendEmail():
    message = MIMEMultipart()
    message.attach(MIMEText(content, 'plain', 'utf-8'))
    message['From'] = "{}".format(sender)  # 发件人
    message['To'] = ",".join(receivers)  # 收件人
    message['Subject'] = title  # 邮件主题

    try:
        smtpObj = smtplib.SMTP_SSL(mail_host, 465)  # 启用SSL发信, 端口一般是465
        smtpObj.login(mail_user, mail_pass)  # 登录验证
        smtpObj.sendmail(sender, receivers, message.as_string())  # 发送
        print("mail has been send successfully.")
    except smtplib.SMTPException as e:
        print(e)

if __name__ == '__main__':
    print (time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()))
    sendEmail()

还有就是，针对QQ邮箱的一系列代码，是这次测试的作业，自动生成测试报告，并自动发送添加报告为附件的邮件

简单的软件测试代码 test_job.py：

# -*- coding: utf-8 -*-

import unittest


def sum(a, b):
    return a + b


def sub(a, b):
    return a - b


class TestZuoYe(unittest.TestCase):

    @classmethod
    def setUpClass(cls):
        print('')

    @classmethod
    def tearDownClass(cls):
        print('')


    def test_Sum(self):
        self.assertEqual(4, sum(3, 1))
        self.assertNotEqual(8, sum(3, 1))

    def test_Sub(self):
        self.assertEqual(2, sub(3, 1))
        self.assertNotEqual(8, sub(3, 1))

if __name__ == '__main__':
    unittest.main()

然后是发送邮件 sendmail.py：

# -*- coding:utf-8 -*-

from HTMLTestRunner import HTMLTestRunner
from email import encoders
from email.mime.text import MIMEText
from email.header import Header
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
import smtplib
import unittest
import time
import os


# 定义发送邮件
def send_mail(file_new):

    msg_from = ''  # 发送方邮箱
    passwd = ''  # 填入发送方邮箱的授权码
    msg_to = ''  # 收件人邮箱

    msg_subject = ""  # 邮件主题
    msg_content = ""  # 邮件正文

    msg = MIMEMultipart()
    # 邮件正文是MIMEText:
    msg.attach(MIMEText(msg_content, 'plain', 'utf-8'))

    # # 构造附件，传送当前目录下的 .txt 文件
    # att1 = MIMEText(open('mybook.txt', 'rb').read(), 'base64', 'utf-8')
    # att1["Content-Type"] = 'application/octet-stream'
    # att1["Content-Disposition"] = 'attachment; filename="file1.txt"'
    # msg.attach(att1)

    # 添加附件，发送一个 .html文件
    with open(file_new, 'rb') as f:
        mime = MIMEBase('html', 'html')
        # 加上必要的头信息
        mime.add_header('Content-Disposition', 'attachment', filename=os.path.basename(file_new))
        mime.add_header('Content-ID', '<0>')
        mime.add_header('X-Attachment-Id', '0')
        # 把附件的内容读进来
        mime.set_payload(f.read())
        # 用Base64编码
        encoders.encode_base64(mime)
        msg.attach(mime)

    msg['Subject'] = Header(msg_subject, 'utf-8')  # 主题
    msg['From'] = msg_from
    msg['To'] = msg_to

    try:
        s = smtplib.SMTP_SSL("smtp.qq.com", 465)  # 邮件服务器及端口号
        s.login(msg_from, passwd)
        s.sendmail(msg_from, msg_to, msg.as_string())
        print('发送成功!')
    except s.SMTPException as e:
        print("发送失败!")
    finally:
        s.quit()


# 查找测报告目录，找到最新生成的测试报告文件
def new_report(testreport):
    lists = os.listdir(testreport)
    lists.sort(key=lambda fn: os.path.getmtime(testreport + "\" + fn))
    file_new = os.path.join(testreport, lists[-1])
    print(file_new)
    return file_new


if __name__ == '__main__':
    # 测试用例存放位置
    test_dir = 'E:ALL_DemoPy_DemoJob3ExamCase'
    # 测试报告存放位置
    test_report = 'E:ALL_DemoPy_DemoJob3ExamReport'

    discover = unittest.defaultTestLoader.discover(test_dir, 'test_*.py')

    now = time.strftime("%Y-%m-%d_%H_%M_%S_")
    filename = test_report + '\' + now + 'result.html'
    fp = open(filename, 'wb')
    runner = HTMLTestRunner(stream=fp,
                            title='测试报告',
                            description='用例执行情况:')
    runner.run(discover)
    fp.close()

    new_report = new_report(test_report)
    send_mail(new_report)  # 发送测试报告
