4.1 预定订单初始化

# 12306.funk12306.Funk12306.buy_ticket

        # 检查用户是否保持登录成功
        url = 'https://kyfw.12306.cn/otn/login/checkUser'
        data = {'_json_att': ''}
        resp = self.s.post(url, data=data)
        print(json.loads(resp.text))

        # 点击预定
        url = 'https://kyfw.12306.cn/otn/leftTicket/submitOrderRequest'
        data = {
            'secretStr': secretStr,
            'train_date': train_date,
            'back_train_date': train_date,
            'tour_flag': 'dc',  # dc 单程 wf 往返
            'purpose_codes': 'ADULT',  # 成人
            'query_from_station_name': from_station,
            'query_to_station_name': to_station,
            'undefined': ''
        }
        resp = self.s.post(url, data=data)
        print(resp.text)

        # 订单初始化 获取REPEAT_SUBMIT_TOKEN key_check_isChange
        url = 'https://kyfw.12306.cn/otn/confirmPassenger/initDc'
        data = {'_json_att': ''}
        response = self.s.post(url, data=data)
        repeat_submit_token = re.search(r"var globalRepeatSubmitToken = '([a-z0-9]+)';",
                                        response.content.decode()).group(1)
        key_check_isChange = re.search("'key_check_isChange':'([A-Z0-9]+)'", response.content.decode()).group(1)

4.2 获取用户信息

# 12306.funk12306.Funk12306.buy_ticket
        # 获取用户信息
        # 需要 REPEAT_SUBMIT_TOKEN
        url = 'https://kyfw.12306.cn/otn/confirmPassenger/getPassengerDTOs'
        data = {'_json_att': '',
                'REPEAT_SUBMIT_TOKEN': repeat_submit_token}
        response = self.s.post(url, data=data)

4.3 解析用户信息

# 12306.utils.parse_passenger

def parsePassenger(passenger_dict):
    passengers_infos_list = passenger_dict['data']['normal_passengers']
    passenger_list = []
    for passenger_info in passengers_infos_list:
        passenger_info_dict = {}
        passenger_info_dict['passenger_name'] = passenger_info.get('passenger_name', '')
        passenger_info_dict['passenger_gender'] = passenger_info.get('sex_name', '')
        passenger_info_dict['passenger_id_type_code'] = passenger_info.get('passenger_id_type_code', '')
        passenger_info_dict['passenger_id_no'] = passenger_info.get('passenger_id_no', '')
        passenger_info_dict['passenger_mobile_no'] = passenger_info.get('mobile_no', '')
        passenger_list.append(passenger_info_dict)
    return passenger_list

4.4 获取乘客信息列表

# 12306.funk12306.Funk12306.buy_ticket

        # 解析并构造乘客信息列表
        passenger_list = parsePassenger(json.loads(response.content))
        print('获取乘客信息有：')
        pprint(passenger_list)
        passenger_info_dict = passenger_list[int(input('输入要购票的乘车人的下标'))]

4.5 解析坐席类型

经过不断的抓包，尝试获取坐席类型的编码

# 12306.utils.parse_seat_type

seat_type_dict = {
    "erdengzuo": "O",  # 二等座
    "yingwo": "3",  # 硬卧
    "yingzuo": "1",  # 硬座
    "wuzuo": "1",  # 无座
    "ruanwo": "4",  # 软卧
    "ruanzuo": "2",  # 软座
    "dongwo": "F",  # 动卧
    "yidengzuo": "M",  # 一等座
    "gaojiruanwo": "6",  # 高级软座
    "shangwuzuo": "9",  # 商务座
    "tedengzuo": "P",  # 特等座
}

4.6 构造乘客信息

# 12306.funk12306.Funk12306.buy_ticket

        # 坐席类型
        try:
            seat_type = seat_type_dict[input('请输入要购买的坐席类型的拼音，如果输入错误，将强行购买无座，能回家就行了，还要tm什么自行车！：')]
        except:
            seat_type = seat_type_dict['wuzuo']

        # 构造乘客信息
        passengerTicketStr = '%s,0,1,%s,%s,%s,%s,N' % (
            seat_type, passenger_info_dict['passenger_name'],
            passenger_info_dict['passenger_id_type_code'],
            passenger_info_dict['passenger_id_no'],
            passenger_info_dict['passenger_mobile_no'])
        oldPassengerStr = '%s,%s,%s,1_' % (
            passenger_info_dict['passenger_name'],
            passenger_info_dict['passenger_id_type_code'],
            passenger_info_dict['passenger_id_no'])
        
        # 检查选票人信息
        url = 'https://kyfw.12306.cn/otn/confirmPassenger/checkOrderInfo'
        data = {
            'cancel_flag': '2',  # 未知
            'bed_level_order_num': '000000000000000000000000000000',  # 未知
            'passengerTicketStr': passengerTicketStr.encode('utf-8'),  # O,0,1,靳文强,1,142303199512240614,18335456020,N
            'oldPassengerStr': oldPassengerStr.encode('utf-8'),  # 靳文强,1,142303199512240614,1_
            'tour_flag': 'dc',  # 单程
            'randCode': '',
            'whatsSelect': '1',
            '_json_att': '',
            'REPEAT_SUBMIT_TOKEN': repeat_submit_token
        }
        resp = self.s.post(url, data=data)
        print(resp.text)
