每日一课 | 定时执行Python脚本自动发送QQ邮件

【导语】：你是否需要每周手动给leader发送工作邮件，每次都需要重复性工作，那么我们来用python吧，来设置定时任务！

一、代码编写定时任务脚本

# coding: utf-8 import pandas as pd import datetime from sqlalchemy import create_engine import smtplib from email.header import Header from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart from email.mime.application import MIMEApplication import warnings warnings.filterwarnings("ignore") # 用于排除警告 def znf_jxh(): # 初始化数据库连接，使用pymysql模块# MySQL的用户：root, 密码:123456, 端口：3306,数据库：test con = create_engine('mysql+pymysql://root:123456@127.0.0.1:3306/test') # 查询语句，选出表中的所有数据 sql = '''SELECT day1,COUNT(DISTINCT a.uid) AS '活跃', COUNT(DISTINCT CASE WHEN day2-day1 = 1 THEN a.uid END) 次留, COUNT(DISTINCT CASE WHEN day2-day1 = 3 THEN a.uid END) 三留, COUNT(DISTINCT CASE WHEN day2-day1 = 7 THEN a.uid END) 七留, CONCAT(COUNT(DISTINCT CASE WHEN day2-day1 = 1 THEN a.uid END)/COUNT(DISTINCT a.uid) * 100,'%%') as 次留存率, CONCAT(COUNT(DISTINCT CASE WHEN day2-day1 = 3 THEN a.uid END)/COUNT(DISTINCT a.uid) * 100,'%%') as 三日留存率, CONCAT(COUNT(DISTINCT CASE WHEN day2-day1 = 7 THEN a.uid END)/COUNT(DISTINCT a.uid) * 100,'%%') as 七日留存率 FROM (SELECT uid, DATE_FORMAT(dayno,'%%Y%%m%%d') as day1 from aui where app_name = '相机') AS a LEFT JOIN (SELECT uid, DATE_FORMAT(dayno,'%%Y%%m%%d') as day2 from aui where app_name = '相机') AS b ON a.uid = b.uid GROUP BY a.day1;''' # read_sql_query的两个参数: sql语句，数据库连接 df = pd.read_sql_query(sql, con=con) print("读取数据成功！！！") df.to_excel(r"C:/Users/cherich/Desktop/产品拆分.xlsx", index=False) def send_email(): mail_user = '*********@qq.com' # 邮箱登录名，次处使用QQ邮箱，填写QQ号即可，不用带@qq.com mail_pass = '*********' # QQ邮箱授权码，如何获取可百度 sender = '*********@qq.com' # 发件人 receivers = ['*********@qq.com'] # 收件人列表，list形式 # chaosong = ['*********@qq.com'] # 抄送人列表，list形式 # 设置邮件体对象，对象类型为 mixed，可以发送附件 subject = "每日发送销售订单产品拆分列表" # 邮件主题 content = "发送时间:" + str(a) + "n" + "订单时间：" + str(b) + "到" + str(c) # 邮件摘要 msg = MIMEMultipart() # 邮件体对象，此处可加入参数，具体可百度 msg.attach(MIMEText(content, 'plain', 'utf-8')) # 邮件正文 text/plain # 中文需参数‘utf-8’，单字节字符不需要 msg['subject'] = Header(subject, 'utf-8') # 加入邮件主题 msg['From'] = "{}".format(sender) # 加入邮件发送人 msg['To'] = ",".join(receivers) # 加入邮件接收人 # 加入附件 File2 = r"C:/Users/cherich/Desktop/产品拆分.xlsx" # 如果是定时发送的报表，此处可以写死 attFile = MIMEApplication(open(File2, 'rb').read()) attFile.add_header('Content-Disposition', 'attachment', filename=File2) msg.attach(attFile) if __name__ == '__main__': try: # 发送邮件，参数设置 sftp_obj = smtplib.SMTP_SSL(host='smtp.qq.com', port=465) sftp_obj.login(mail_user, mail_pass) sftp_obj.sendmail(sender, receivers, msg.as_string()) sftp_obj.quit() sftp_obj.close() print('nThe email has been sent successfully') except Exception as err: print('n Email failed to be sent out.
