Python脚本抓取大乐透开奖结果核对定投号码邮件通知

    最近学习了一下Python的基础,想写个东西练练手。正好每次跟号的大乐透还需要手动兑奖或者去彩票站兑奖,自己写一个脚本自动抓取开奖结果,核对开奖金额后邮件通知。

整体思路:

  1. 找可抓取开奖结果网站
  2. 找可以发送邮件的免费服务器
  3. 写抓取、兑奖、发邮件脚本
  4. 设定自动执行脚本

踩坑:

  1. 2.7.3版本,使用requests、urllib3包的ssl有问题,最后也没解决了,执行的时候能执行,但是有警告信息,3.1上没问题。
  2. 找的网站,抓取历史数据的时候,频繁抓取会被限制,需要设定执行频率或者更改proxy。

详细过程:

1,找可抓取开奖结果网站

要求:开奖后及时更新结果;结果数据方便解析;

最后选中了彩经网的,开奖半小时内更新,而且结果只有一个table,很简单,方便解析。

例:https://www.cjcp.com.cn/kaijiang/data/ajax_dlt.php?qh=2021146

2,找免费发送的邮件服务器

 要求:常用QQ邮箱,那些非互联网上认证的邮件发送服务器(域名和出口IP不一致)的邮件会被拒收,所以需要找一个互联网上认证的邮件服务器进行发送。横向比较后,选择了163邮箱(比QQ邮箱认证简单一些)。

3,写抓取、兑奖、发邮件脚本

抓取:

#从彩经网获取大乐透开奖号码,
#lot:彩票期数,例如:2021140
def getlottery(lot):
    target = "https://www.cjcp.com.cn/kaijiang/data/ajax_dlt.php?qh=" + lot
    #设置requests header
    headers={
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36',
        'Host': 'www.cjcp.com.cn',
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3'
    }
    req = requests.get(url=target,headers=headers,verify=False)
    #req = requests.get(url=target,verify=False)
    #print(req.text)
    
    red = []
    #blue = []
    num=""
    #txt=(BS(req.text,'lxml')).splitlines()
    txt=req.text.splitlines()
    for ln in txt:
        if "qiu_r" in ln:
            num = ln.replace('',"").replace("","").strip()
            #print(num)
           # red += num
            red.append(num)
        elif "qiu_b" in ln:
            #print(ln)
            num = ln.replace('',"").replace("","").strip()
            #print(num)
            #blue += ln.replace('',"").replace("","")
            red.append(num)
    return red

核对:

#查看是否中奖
#buy_num:买的号码,单注形式 例如:04,08,14,33,35:06,10
#prize_num:开奖号码,例如:03, 20, 25, 30, 34, 02, 09]
#return:中几等奖,0:未中奖,1-9中的奖的等数
def checkprized(buy_num,prize_num):

    prized = '0'
    #开奖红球
    pred = prize_num[0:5]
    #开奖蓝球
    pblue = prize_num[5:7]
    #购买红球
    br = buy_num.split(':')[0]
    #购买蓝球
    bb = buy_num.split(':')[1]
    #print('bought:',br,':::',bb)
    rcnt = 0
    bcnt = 0
    #红球匹配数
    for num in br.split(','):
        if num in pred:
            rcnt += 1
    #蓝球匹配数
    for num in bb.split(','):
        if num in pblue:
            bcnt += 1
    #中奖规则
    if rcnt == 5 and bcnt == 2:
        prized = '1'
    elif rcnt == 5 and bcnt == 1:
        prized = '2'
    elif rcnt == 5 and bcnt == 0:
        prized = '3'
    elif rcnt == 4 and bcnt == 2:
        prized = '4'
    elif rcnt == 4 and bcnt == 1:
        prized = '5'
    elif rcnt == 3 and bcnt == 2:
        prized = '6'
    elif rcnt == 4 and bcnt == 0:
        prized = '7'
    elif (rcnt == 3 and bcnt == 1) or\
    (rcnt == 2 and bcnt == 2):
        prized = '8'
    elif rcnt == 3 or \
    (bcnt == 1 and rcnt ==2) or \
    (bcnt == 2 and rcnt ==1) or \
    bcnt == 2:
        prized = '9'
    else:
        prized = '0'
    return prized

计算金额:

#根据中几等奖计算中奖金额
#prized:中几等奖
#return:中奖金额,1,2等奖浮动按照1千万和2百万计算
def countpay(prized):
    pay = 0
    for i in prized:
        if i == '0':
            continue
        elif i == '1':
            pay += 10000000            
        elif i == '2':
            pay += 2000000            
        elif i == '3':
            pay += 10000            
        elif i == '4':
            pay += 3000            
        elif i == '5':
            pay += 300            
        elif i == '6':
            pay += 200            
        elif i == '7':
            pay += 100            
        elif i == '8':
            pay += 15            
        elif i == '9':
            pay += 5            
    #print "中奖金额:" + str(pay)
    return pay

发送邮件

    #设置email信息
    #邮件内容设置
    message = MIMEText(content,'plain','utf-8')
    #邮件主题

4,定时执行

扔在云上的Linux服务器上,设定Crontab

crontab -u python -e
