python发送邮件

本文主要是针对统计数据库中数据，并将数据存在Excel中，最后通过邮件将Excel发送给指定用户；直接上代码。

一、日志配置文件 Logger.conf

############################################
[loggers]
keys = root,example01,example02
[logger_root]
level = DEBUG
handlers = hand01,hand02
[logger_example01]
handlers = hand01,hand02
qualname = example01
propagate = 0
[logger_example02]
handlers = hand01,hand03
qualname = example02
propagate = 0
############################################
[handlers]
keys = hand01,hand02,hand03
[handler_hand01]
class = StreamHandler
level = DEBUG
formatter = form01
args = (sys.stderr,)
[handler_hand02]
class = FileHandler
lever = DEBUG
formatter = form01
args = ('./Result_count.log','a')
[handler_hand03]
class = handlers.RotatingFileHandler
lever = INFO
formatter = form01
args = ('./Result_count.log','a',10*1024*1024,5)
############################################
[formatters]
keys = form01,form02
[formatter_form01]
format = %(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s
datefmt = %Y-%m-%d %H:%M:%S
[formatter_form02]
format = %(name) -12s: %(levelname) -8s %(message)s
datefmt = %Y-$m-%d %H:%M:%S

二、读取配置文件的程序：Log.py

#!/usr/bin/python
#encoding=utf-8
import logging.config
logging.config.fileConfig("Logger.conf")

def debug(message):
logging.debug(message)

def warning(message):
logging.warning(message)

def info(message):
logging.info(message)

三、连接数据库并将统计结果存成Excel

#!/usr/bin/python
# -*- coding:utf-8 -*-
'''
方法：通过pymsql模块连接mysql数据库，然后通过游标cursor查询SQL语句将结果存储在Excel文件中，其中Excel的生成使用xlwt实现的。

import pymysql
import xlwt
import datetime
from Log import *


def Select_data():
    conn = pymysql.connect(host='x.x.x.x', port=xxx, user='root', passwd='PxxxxxxxSH', db='xx', charset='utf8')
    logging.info(u"#连接mysql数据库成功！")
    logging.info(u"#使用cursor()方法获取操作游标；")
    cursor = conn.cursor()
    logging.info(u"#使用execute方法执行SQL语句,并将统计结果存储在effect_row变量中；")
    today = datetime.datetime.today() #获取今天的日期.
    yesterday = today - datetime.timedelta(days=1)  #获取昨天的日期.
    tomorrow = today + datetime.timedelta(days=1)   #获取明天的日期.
    today_a = datetime.datetime(today.year, today.month, today.day, 0, 0, 0) #获取今天凌晨的时间.
    yesterday_b = datetime.datetime(yesterday.year, yesterday.month, yesterday.day, 0, 0, 0)#获取昨天凌晨的时间.
    tomorrow_c = datetime.datetime(tomorrow.year, tomorrow.month, tomorrow.day, 0, 0, 0) #获取明天凌晨的时间.
    #格式化时间输出，用于给Excel起名时使用。
    sheet_time = datetime.datetime.now()
    book_mark = sheet_time.strftime('%Y%m%d')

    #获取所有的记录列表，也就是总行数.
    #print effect_row  #打印总行数.
    #获取统计信息，并将结果存在row_3中.
    row_3 = cursor.fetchall()
    #print row_3 #打印统计内容.
    #获取上述SQL语句中的检索条件名称（将要成为Excel第一行的表头）。
    fields = cursor.description
    logging.info(u"#依次做提交请求和关闭断开操作；")
    conn.commit()
    cursor.close()
    conn.close()
    return row_3,book_mark,fields
    
def WritToExcel():
    Data = Select_data()
    logging.info(u"#将字段名写入到EXCEL表头；")
    workbook = xlwt.Workbook(encoding='utf-8')
    #创建Excel中的一个sheet，并命名且为可重写状态。
    sheet = workbook.add_sheet('result_count',cell_overwrite_ok=True)
    #构造一个列表VnameList，用于将上述表头重命名，一定要一一对应。
    VnameList = [u"用户名","MAC",u"微信ID","QQ",u"新浪微博",u"腾讯微博",u"腾讯视频",u"京东商城",u"淘宝",u"今日头条",u"美团"]
    logging.info(u"#将VnameList中的虚拟身份依次填入Excel中；")
    for field in range(0,len(VnameList)):
        sheet.write(0,field,VnameList[field].encode("utf-8"))

    #根据横纵坐标依次录入查询到的信息值。
    row = 1
    col = 0
    for row in range(1,len(Data[0])+1):
        for col in range(0,len(Data[2])):
            sheet.write(row,col,u'%s'%Data[0][row-1][col])
    logging.info(u"#将Excel文件保存下来；")
    logging.info(u"#保存成功！！！\n")
    workbook.save('./Count_result%s.xls'%Data[1].encode("utf-8"))

if __name__=="__main__":
    WritToExcel()

四、邮件发送程序

#!/usr/bin/python
# -*- coding:utf-8 -*-

    logging.info(u"# 登录邮箱服务器成功；")

    receiver=['923xxxx@qq.com','fanxxx@pxxxxx.com']
    #生成今天的日期，格式化输出为年月日；生成昨天的日期，格式化输出为年月日
    sheet_time = datetime.datetime.now()
    book_mark = sheet_time.strftime('%Y%m%d')
    today = datetime.datetime.today()  
    yesterday = today - datetime.timedelta(days=1)
    yesterday_b = datetime.datetime(yesterday.year, yesterday.month, yesterday.day, 0, 0, 0)

        while True:

            logging.warning(u"#邮件发送成功！！！")
            break
