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：
找可抓取开奖结果网站找可以发送邮件的免费服务器写抓取、兑奖、发邮件脚本设定自动执行脚本
踩坑：
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。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：/kaijiang/data/ajax_dlt.php?qh=146
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：140def getlottery(lot):target = "/kaijiang/data/ajax_dlt.php?qh=" + lot#设置requests headerheaders={'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': '','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('<span class="qiu_r">',"").replace("</span>","").strip()#print(num)# red += numred.append(num)elif "qiu_b" in ln:#print(ln)num = ln.replace('<span class="qiu_b">',"").replace("</span>","").strip()#print(num)#blue += ln.replace('<span class="qiu_b">',"").replace("</span>","")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 = 0bcnt = 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 = 0for i in prized:if i == '0':continueelif 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
def send(subject,content,receivers=['xxxxxxxx@']):#设置服务器所需信息，使用163邮箱发送#邮箱服务器地址mail_host = ''#用户名mail_user = 'xxxxxxxx'#密码(部分邮箱为授权码) mail_pass = 'xxxxxxxx'#邮件发送方邮箱地址sender = 'xxxxxxxx@' #邮件接受方邮箱地址，注意需要[]包裹，这意味着你可以写多个邮件地址群发#receivers = ['xxxxxxxx@'] #设置email信息#邮件内容设置message = MIMEText(content,'plain','utf-8')#邮件主题 message['Subject'] = subject #发送方信息message['From'] = sender #接受方信息message['To'] = receivers[0] #登录并发送邮件try:smtpObj = smtplib.SMTP() #连接到服务器smtpObj.connect(mail_host,25)#登录到服务器smtpObj.login(mail_user,mail_pass) #发送smtpObj.sendmail(sender,receivers,message.as_string()) #退出smtpObj.quit() except smtplib.SMTPException as e:print('error',e) #打印错误#send('测试邮件','测试内容')

4，定时执行
扔在云上的Linux服务器上，设定Crontab
crontab -u python -e0 21 * * * /opt/sh/check_everyday.py
