Python实现全自动购买火车票！抢票回家过年咯

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
1.首先实现使用selenium登陆12306
​ 这里实现了使用selenium登陆12306，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。
