这个是实现结果，因为一天只能取消三次，所以最后一步点击确认被我注释了

python火车票订票模拟 python火车票购买程序_python火车票订票模拟

1.首先实现使用selenium登陆12306

关于使用selenium实现12306登陆可以看我的另一篇文章这里实现了使用selenium登陆12306，这次是基于上次的代码进行修改实现全自动购买车票的实现全自动登陆12306链接

2.根据上面实现登陆后，实现购买火车票还需两步

这里只进行了二等座的查询和购票，想要买其他的自己也可以进行修改 1.进行车票的查询这里面需要注意的是在输入目的地和起始地时需要先click一下文本框browser.find_element_by_id(‘fromStationText’).click() 不然输入的地址无效还有将日期的只读属性去掉

def search_railway_ticket(fromstation,tostation,train_date): 
    # 火车票页面查询url 
    search_url = 'https://kyfw.12306.cn/otn/leftTicket/init?linktypeid=dc' 
    # 转到查询车次页面 
    browser.get(search_url) 
    time.sleep(2) 
    #输入出发地 
    WebDriverWait(browser, 1000).until( 
        EC.presence_of_element_located((By.ID, 'fromStationText')) 
    ) 
    #先点击一下 
    browser.find_element_by_id('fromStationText').click() 
    browser.find_element_by_id('fromStationText').send_keys(fromstation) 
    browser.find_element_by_id('fromStationText').send_keys(Keys.ENTER) 
    time.sleep(1) 
    WebDriverWait(browser, 1000).until( 
        EC.presence_of_element_located((By.ID, 'toStationText')) 
    ) 
    #输入目的地 
    browser.find_element_by_id('toStationText').click() 
    browser.find_element_by_id('toStationText').send_keys(tostation) 
    browser.find_element_by_id('toStationText').send_keys(Keys.ENTER) 
    time.sleep(5) 
    #将日期的只读属性去掉 
    js = 'document.getElementById("train_date").removeAttribute("readonly")' 
    browser.execute_script(js) 
    #去掉原本的时间 
    WebDriverWait(browser, 1000).until( 
        EC.presence_of_element_located((By.ID, 'train_date')) 
    ) 
    browser.find_element_by_id("train_date").clear() 
    #输入出发时间 
    browser.find_element_by_id('train_date').send_keys(train_date) 
    # 等待查询按钮是否可用 
    WebDriverWait(browser, 1000).until( 
        EC.element_to_be_clickable((By.ID, 'query_ticket')) 
    ) 
    searBtn = browser.find_element_by_id('query_ticket') 
    searBtn.click() 
    print('点击按钮')

2.购买火车票在这个函数中需要注意的是最好把最后一步注释掉 browser.find_element_by_id(‘qr_submit_id’).click() 因为一天只能取消3次订单

def buy_ticket(fromstation,tostation,train_date,train_number,passenger): 
 
    #查询火车票 
    search_railway_ticket(fromstation,tostation,train_date) 
    time.sleep(5) 
    #获取每一个车次的信息 
    tr_list = browser.find_elements_by_xpath('.//tbody[@id="queryLeftTable"]/tr[not(@datatran)]') 
    for tr in tr_list: 
        #获取车次号 
        number = tr.find_element_by_class_name('number').text 
        if number in  train_number: 
            #获取是否还有票 
            left_ticket = tr.find_element_by_xpath('./td[4]').text 
            if left_ticket =='有'or left_ticket.isdigit: 
                print(f'{number}还有票') 
                #点击预订 
                orderBtn = tr.find_element_by_class_name('btn72') 
                orderBtn.click() 
                time.sleep(5) 
                #获取12306中乘客的信息 
                passenger_list = browser.find_elements_by_xpath('//*[@id="normal_passenger_id"]/li') 
                for li in passenger_list: 
                    name = li.find_element_by_xpath('./label').text 
                    print(name) 
                    #配对12306人名 
                    if name == passenger: 
                        li.find_element_by_tag_name('input').click() 
                #提交订单 
                submit = browser.find_element_by_id('submitOrder_id') 
                submit.click() 
                WebDriverWait(browser, 1000).until( 
                    EC.element_to_be_clickable((By.ID, 'qr_submit_id')) 
                ) 
                #一天只能取消3次 所以最好把最后一步注释了 
                browser.find_element_by_id('qr_submit_id').click() 
                print('已经提交订单') 
                break

下面是源代码

测试的时候可以把#click_captcha()这个点击验证码的去掉自己手动点击，这样就不用扣超级鹰的积分(有钱的话当我没说)，留下了贫穷的泪水。
