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 = ['453032441@qq.com'] #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)
