python 发送带有附件的邮件

    在selenium运行完成，想要把测试报告和截图发送指定的邮箱，需要先把测试报告和截图文件夹打包成压缩文件然后一起发送，下面就是代码：

1.压缩文件

import os,zipfile

#压缩文件
def compression():
    try:
        fantasy_zip = zipfile.ZipFile(压缩文件存放路径,'w')
        for folder,subfolders,files in os.walk(测试报告文件夹路径):
            for file in files:
                fantasy_zip.wirte(os.path.join(folder,file),
                                  os.path.relpath(os.path.join(folder,file),测试报告文件夹路径),
                                  compress_type=zipfile.ZIP_DEFLATED)
    except:
        logger.warning('压缩文件失败')
        raise

2.添加到邮件附件

import mimetype,os
from email.mime.base import MIMEBase
from email import encoders

def annex():
    try:
        data = open(压缩文件名,'rb')
        ctype,encoding = mimetype.guess_type(压缩文件名)
        if ctype is None or encoding is not None:
            ctype = 'application/x-zip-compressed'
        maintype,subtype = ctype.split('/',1)
        file_msg = MIMEBase(maintype,subtype)
        file_msg.set_payload(data.read())
        data.close()
        encoders.encode_base64(file_msg)
        basename = os.path.basename(压缩文件名)
        file_msg.add_header('Content-Disposition', 'attachment', filename=basename)
        return file_mag
    except:
        logger.warning('添加文件失败！')
        raise

3.构造邮件模板

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

def data():
    """邮件内容"""
    # 报告位置进行按时间排序，返回一个最新的测试报告文件,目录格式和保存测试报告的一致
    report_lists = os.listdir(report['report_file_dir'])
    report_lists.sort(key=lambda fn: os.path.getmtime(report['report_file_dir'] + '\' + fn))
    report_new_file = os.path.join(report['report_file_dir'], report_lists[-1])
    # 读取最新报告的内容
    f = open(report_new_file, 'rb')
    main_body = f.read()
    f.close()
    try:
        self.compression()
        message_annex = MIMEMultipart()
        annex = self.annex()
        # """构建根容器"""
        test = MIMEText(main_body,'html','utf-8')
        message_annex['From'] = "{}".format(email['username'])
        message_annex['To']=",".join(email['receivers'])
        message_annex['Subject']="OMS 自动化用例测试报告"

        # """将文本和附件内容添加到邮件"""
        message_annex.attach(annex)
        message_annex.attach(test)
        fullTest = message_annex.as_string()
        return fullTest
    except:
        logger.error('邮件内容错误！！！')
        raise

4.发送邮件

import os,time,smtplib   

def send_eamil():
    try:
        message = self.data()
        smtpObj=smtplib.SMTP_SSL(email['host'],465)
        smtpObj.login(email['username'],email['password'])
        flag = True
        while flag:
            try:
                smtpObj.sendmail(email['username'],email['receivers'],message)
                smtpObj.quit()
                flag = False
            except:
                logger.info('发送失败！！！正在重新发送...')
                time.sleep(2)
                continue
        logger.info('邮件发送成功')
    except:
        logger.warning('配置有误！！！')
        raise

整合起来代码如下

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
import smtplib,time,os,zipfile,mimetypes

class SendEmail():
    """发送邮件"""

    def send_eamil(self):
        try:
            message = self.data()
            smtpObj=smtplib.SMTP_SSL(email['host'],465)
            smtpObj.login(email['username'],email['password'])
            flag = True
            while flag:
                try:
                    smtpObj.sendmail(email['username'],email['receivers'],message)
                    smtpObj.quit()
                    flag = False
                except:
                    logger.info('发送失败！！！正在重新发送...')
                    time.sleep(2)
                    continue
            logger.info('邮件发送成功')
        except:
            logger.warning('配置有误！！！')
            raise

    def data(self):
        """邮件内容"""

        report_lists.sort(key=lambda fn: os.path.getmtime(report['report_file_dir'] + '\' + fn))
        report_new_file = os.path.join(report['report_file_dir'], report_lists[-1])
        # 读取最新报告的内容
        f = open(report_new_file, 'rb')
        main_body = f.read()
        f.close()
        try:

            # """将文本和附件内容添加到邮件"""
            message_annex.attach(annex)
            message_annex.attach(test)
            fullTest = message_annex.as_string()
            return fullTest
        except:
            logger.error('邮件内容错误！！！')
            raise

    def compression(self):

            fantasy_zip.close()
        except:
            logger.warning('文件夹压缩失败')
            raise

    def annex(self):
        """将zip添加附件"""
        try:
