selenium+python实现12306自动化抢火车票（二）

往期回顾：

1、根据乘车人姓名匹配，支持1人或多人选择

定位出所有乘车人的元素集，根据姓名集合去元素集里循环迭代匹配，匹配上了操作选中

go 复制代码

ele_all=driver.find_elements(By.XPATH, "//*[@id='normal_passenger_id']/li")#定位所有乘车人for i in name_list:    for j in range(len(ele_all)):        if i==ele_all[j].text:            driver.find_element(By.ID, "normalPassenger_{0}".format(j)).click()#选择乘车人            print("选择乘车人【{0}】".format(i))

2、车次未开放或已售完，持续查询

车次售完了，或还未开售，这时，预定按钮是灰色不可点击的，这里要做特殊处理，可点击的预定td标签下有a标签，不可点击预定td标签下没有a标签，这时可根据是否有a标签判断预定按钮是否可点击，可点击继续后续流程，不可点击，继续进行查询操作，持续循环，直至有票了或车票开售

sql 复制代码

bool = Truewhile bool:    driver.find_element(By.ID, "query_ticket").click() #点查询    print("{0}------{1},日期:【{2}】,车次:【{3}】,查询中～".format(from_city,to_city,date,train_no))    ele=driver.find_elements(By.XPATH, "//div[@class='train']") #列表所有车次    for i in range(len(ele)):        a=True        try:            ele1=driver.find_element(By.XPATH, "//div[@id='train_num_{0}']/../../td[13]/a".format(i))        except:            a=False            print("{0}------{1},日期:{2},车次:{3},车次不存在/还未开售/已售完～".format(from_city, to_city, date, train_no))        if train_no in ele[i].text and a:            print("{0}------{1},日期:【{2}】,车次:【{3}】,已查到车次，且有可买的车票～".format(from_city, to_city, date,train_no))            ele1.click() #点预定            print("{0}------{1},日期:【{2}】,车次:【{3}】,预定中～".format(from_city, to_city, date,train_no))            try:                driver.find_element(By.ID, "login")                driver.find_element(By.ID, "login_close").click()                ele1.click() #点预定                print("{0}------{1},日期:【{2}】,车次:【{3}】,再次预定中～".format(from_city, to_city, date, train_no))            except:                pass            bool=False            break

3、根据不同车次座位类别，选对应的座位席位

go 复制代码

ticket_info = driver.find_elements(By.XPATH, "//*[@id='check_ticketInfo_id']/tr") #确认页，乘车人车票信息for i in range(len(ticket_info)):    ticket_info_seat=driver.find_elements(By.XPATH, "//*[@id='check_ticketInfo_id']/tr[{0}+1]/td[2]".format(i)) #确认页，乘车人座位类别    if "一等座"==ticket_info_seat[0].text and list[i] in ("1A","2A","1C","2C","1D","2D","1F","2F"):        driver.find_element(By.ID, "{0}".format(list[i])).click()    elif "二等座"==ticket_info_seat[0].text and list[i] in ("1A","2A","1B","2B","1C","2C","1D","2D","1F","2F"):        driver.find_element(By.ID, "{0}".format(list[i])).click()    elif "商务座" == ticket_info_seat[0].text and list[i] in ("1A","2A","1C","2C","1F","2F"):        driver.find_element(By.ID, "{0}".format(list[i])).click()
