Python自动化抢购12306火车票通常涉及使用第三方库,如`lxml`、`requests`以及一些时间处理模块,如`time`和`datetime`。以下是一个简化的示例框架,展示了如何使用`requests`库来访问12306网站并尝试获取车票信息:
```python
import requests
from lxml import etree
import time
# 登录12306账户
def login(username, password):
session = requests.Session()
login_url = "https://kyfw.12306.cn/login/init"
session.get(login_url)
data = {
'username': username,
'password': password,
'appid': 'APP_ID', # 实际应用ID
'passwordType': 'N'
}
response = session.post("https://login.12306.cn/login", data=data)
if '验证码' in response.text: # 验证码未通过的情况处理
print('验证码错误,请检查输入')
return
# 获取登录后的cookie
cookies = session.cookies.get_dict()
return session, cookies
# 抢票函数
def buy_tickets(session, cookies, destination):
url = f"https://kyfw.12306.cn/otn/leftTicket/init?leftTicketDTO.train_date={destination[0]}{destination[1]}&leftTicketDTO.from_station={destination[2]}&leftTicketDTO.to_station={destination[3]}"
response = session.get(url, cookies=cookies)
# 使用xpath解析页面内容寻找购票链接
tree = etree.HTML(response.content)
ticket_link = tree.xpath('//a[@class="btn-buy"]/@href') # 根据实际网页结构修改XPath
for link in ticket_link:
buy_ticket_url = "https://kyfw.12306.cn" + link
# 购买动作(模拟点击)
session.get(buy_ticket_url) # 这里需要进一步完善,可能需要模拟用户交互,如验证码识别和确认购买
# 示例使用
username = 'your_username'
password = 'your_password'
destination = ('出发日期', '月/日', '出发站', '到达站')
session, cookies = login(username, password)
buy_tickets(session, cookies, destination)
# 每次请求之间适当延时避免触发频率限制
time.sleep(5)
