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:
踩坑:
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',

}
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:

elif rcnt == 3 and bcnt == 2:
prized = '6'
elif rcnt == 4 and bcnt == 0:

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':

#print "中奖金额:" + str(pay)
return pay

4,定时执行
扔在云上的Linux服务器上,设定Crontab
crontab -u python -e
