python3+mysql查询数据并通过邮件群发excel附件
本文实例为大家分享了python3邮件群发excel附件的具体代码,供大家参考,具体内容如下
连接、查询mysql,导入到excel文件,定时群发邮件与附件。
主要用到pymysql ,smtplib , xlwt
#1、导入模块
import pymysql #Python3的mysql模块,Python2 是mysqldb import os import datetime #定时发送,以及日期 import shutil #文件操作 import smtplib #邮件模块 from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart from email.header import Header import time import xlwt #excel写入
#2、连接并查询mysql
def eMysql(mysql_host,mysql_port,mysql_user,mysql_password,mysql_db,sql): try: db = pymysql.connect(host=mysql_host,port=mysql_port,user=mysql_user, password=mysql_password, db=mysql_db,charset = 'utf8')#连接数据库编码注意是utf8,不然中文结果输出会乱码 print("MYSQL CONNECTED.")# 连接数据库 cursor = db.cursor()# 使用cursor()方法获取操作游标 cursor.execute(sql)# 执行SQL语句 print('SQL EXECUTED') results = cursor.fetchall()# 结果 return results print('RESULTS EXECUTED') db.close() # 关闭数据库连接 print('MYSQL CLOSED') except: print('SQL FAILED')
#3、写入excel
def eWrite(fLocate,results,file_sheet,file_subject,style0): try: if os.path.exists(fLocate): os.remove(fLocate) # 如果文件存在,则删除 f = xlwt.Workbook(encoding='utf-8') #打开excel文件 fs = f.add_sheet(file_sheet) #sheet名 subject = list(file_subject) #列表化 for i in range(len(subject)): #找到日期列 if '日期' in subject[i]: col_num=i for i in range(len(subject)): #sheet标题 fs.write(0, i, subject[i]) for i in range(len(results)): #sheet数据,日期列格式为date for j in range(len(results[0])): if j== col_num: fs.write(i + 1, j, results[i][j],style0) else: fs.write(i + 1, j, results[i][j]) for i in range(10): #单元格宽度为 fs.col(i).width=3333 print("WRITE FINISHED") f.save(fLocate) except : print ("WRITE FAILED")
#4、发送邮件
def eSend(sender,receiver,username,password,smtpserver,subject,e_content,file_path,file_name): try: #邮件头 message = MIMEMultipart() message['From'] = sender#发送 message['To'] = ",".join(receiver)#收件 message['Subject'] = Header(subject, 'utf-8') message.attach(MIMEText(e_content, 'plain', 'utf-8'))# 邮件正文 # 构造附件 att1 = MIMEText(open(file_path+file_name,'rb').read(), 'base64', 'utf-8') att1["Content-Type"] = 'application/octet-stream' att1["Content-Disposition"] = "attachment;filename="+file_name message.attach(att1) #执行 smtp = smtplib.SMTP() smtp.connect(smtpserver) #连接服务器 smtp.login(username, password) #登录 smtp.sendmail(sender, receiver, message.as_string()) #发送 smtp.quit() print("SEND") except: print("SEND FAILED")
#5、配置与执行
while True: #配置 #__time_____ ehour=5#定时小时 emin=21#定时分钟 esec=41#定时秒 current_time = time.localtime(time.time()) #当前时间date cur_time = time.strftime('%H%M', time.localtime(time.time())) #当前时间str #__mysql_____ mysql_host = mysql_host #登录host mysql_port =mysql_port #登录port mysql_user = mysql_user #登录名 mysql_password = mysql_password #登录密码 mysql_db = mysql_db #数据库 sql = sql.encode('utf-8') #sql查询语句编码 #__email_____ sender = sender #发件人邮箱 receiver = ['[email protected]'] #收件人邮箱,可以多个(列表形式)群发 # username = username #发件人姓名 password = password #smtp密码,qq是给你分配一串,163是自己设置 smtpserver = smtpserver #邮箱服务器 subject = "Hey,here's something interesting" #邮件标题 e_content = '{0:^27}\n{1:^27}\n{2:^25}\n{3:^25}'.format('i','/ \\','(-----)','(--------)') #邮件正文 #邮件正文 #__file_____ file_path = "D:/" #文件位置 file_name="shit.xls" #文件名 fLocate = file_path + file_name #文件路径 file_subject='Gave', 'you', 'a', 'piece', 'of', 'shit.' #sheet标题 file_sheet='ok' #sheet名 style0=xlwt.XFStyle() style0.num_format_str='YYYY-MM-DD' #操作 if ((current_time.tm_hour == ehour) and (current_time.tm_min == emin) and (current_time.tm_sec == esec)): print ("START") results=eMysql(mysql_host,mysql_port,mysql_user,mysql_password,mysql_db,sql) eWrite(fLocate, results, file_sheet, file_subject,style0) eSend(sender, receiver, username, password, smtpserver, subject, e_content, file_path,file_name) print(cur_time) time.sleep(1)
