分析

我们输入的上海，北京都变成了对应的编号，比如，上海（SHH）、北京（BJP），所以当我们程序进行输入的时候要进行一下处理，12306的一个地方存储着这些城市名与编码对应的文档：

GET请求： https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.8971

点击查询，通过F12找到接口：

GET请求
Request URL: https://kyfw.12306.cn/otn/leftTicket/query?leftTicketDTO.train_date=2020-12-31&leftTicketDTO.from_station=SHH&leftTicketDTO.to_station=BXP&purpose_codes=ADULT

leftTicketDTO.train_date：查询的日期       2020-12-31
leftTicketDTO.from_station：查询的出发地   SHH上海
leftTicketDTO.to_station：查询的目的地     BXP北京  郑州ZZF
purpose_codes：不太清楚这个字段是用来做什么的，就默认吧

整体流程：
执行定时任务，查询12306余票信息，如果有合适的车次，就发送邮件通知。

1、查询余票信息

查询城市编码与城市名称对应信息。

# {'VAP': '北京北'}
def getCityCode1():url = "https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.8971"response = requests.get(url, verify=False)# 将车站的名字和编码进行提取chezhan = re.findall(r'([\u4e00-\u9fa5]+)\|([A-Z]+)', response.text)chezhan_code = dict(chezhan)# 进行交换chezhan_names = dict(zip(chezhan_code.values(),chezhan_code.keys() ))# 打印出得到的车站字典print(chezhan_names)  # {'VAP': '北京北', 'BOP': '北京东',return chezhan_names
# {'北京北':'VAP'}
def getCityCode2():url = "https://kyfw.12306.cn/otn/resources/js/framework/station_name.js?station_version=1.8971"response = requests.get(url, verify=False)# 将车站的名字和编码进行提取chezhan = re.findall(r'([\u4e00-\u9fa5]+)\|([A-Z]+)', response.text)chezhan_code = dict(chezhan)# 进行交换chezhan_names = dict(zip(chezhan_code.keys(),chezhan_code.values() ))# 打印出得到的车站字典print('getCityCode2()',chezhan_names)return chezhan_names

解析余票信息数据

保存数据为csv文件

# 保存数据
def writeData(ticketList):with open(date+from_station+"->"+to_station+'.csv', 'w', encoding='utf-8', newline='') as f:# writer = csv.DictWriter(f, fieldnames=["station_train_code","from_station_name","to_station_name","start_time","arrive_time",#     "lishi","swz_num","zy_num","ze_num","dw_num","gr_num","rw_num","yw_num","rz_num","yz_num","wz_num","qt_num","note_num"])writer = csv.DictWriter(f, fieldnames=[" 车次 ","出发车站","到达车站","出发时间","到达时间"," 历时 ","商务座","一等座","二等座","高级软卧","软卧","动卧","硬卧","软座","硬座","无座","其他","备注"])writer.writeheader()  # 写入表头for each in ticketList:# 逐行写入writer.writerow(each)

效果

2、发送邮件通知

效果

3、定时任务

将查询余票信息的方法封装一下，导入schedule模块

import schedule

if __name__ == '__main__':# 乘车日期date = "2020-12-15"# 出发站from_station = "秦皇岛"# 到达站to_station = "郑州"GET(date,from_station,to_station)# 每小时执行一次# schedule.every().hour.do(GET,date,from_station,to_station)# 每分钟执行一次schedule.every().minute.do(GET,date,from_station,to_station)while True:schedule.run_pending()time.sleep(2)
