具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细说明。
NDC(New Distribution Capability,新分销能力),IATA发布的NDC标准,旨在开发和普及一套全新的、基于互联网XML语言的数据传输标准。
航空公司API接口:航空公司通过接口直接的方式与各代理人、OTA、TMC等建立直销,以更好的销售其机票、辅营、服务等产品。
查订比:衡量航班查询总量与预定量的一个比值,查订比=航班查询量/预定PNR数。
以下结合说明书附图对本申请一种基于NDC的航司数据处理的方法和系统的实施例作进一步详细描述。
本申请实施例公开一种基于NDC的航司数据处理的系统。参照图1和图2,一种基于NDC的航司数据处理的系统包括运营管理平台1、接入网关模块11、交易集群12、搜索集群13和航司接入服务集群14,运营管理平台1设有航空公司自有接口协议15,航空公司自有接口协议15用于适配所有的航空公司接口。通过同一个接口协议,对不同航空公司的航班信息进行整合,方便对资源的同一管理,从而提高了资源获取效率。
参照图1和图3,接入网关模块11用于完成NDC协议标准化适配、流量控制、查订比设置、计费和权利限定的问题,具体的,接入网关模块11包括鉴权单元111、流控单元112和适配内部模型单元113。鉴权单元111用于对用户的请求任务进行权利鉴定,判定用户所能访问的航司。流控单元112用于对系统内任务进行管控,有利于防止因为任务数量与运营管理平台1的处理速度的不匹配造成数据丢失的情况发生。适配内部模型单元113用于将用户端发送的NDC请求协议转换为系统内部模型所适配的数据,便于对任务数据进行统一调度。
参照图1和图2,搜索集群13用于实现航司数据缓存、任务分发和数据聚合,具体的,搜索集群13包括任务拆分单元131、无效任务过滤单元132、缓存命中单元133和缓存击穿单元134。任务拆分单元131用于将获取的任务信息进行拆分,选择任务所适配的航空公司,并将任务依次分给所适配的航空公司。无效任务过滤用于将无效的任务过滤掉,有利于降低运营管理平台1的处理负载。在一个实施例中,任务所对应的航班被取消,则将该任务过滤,不会进入下一个步骤。缓存命中单元133用于提高查询速度,拦截重复请求,降低查订比,缓存击穿单元134用于将未被拦截的任务分发给航司接入服务集群14。
参照图1和图2,具体的,航司接入服务集群14包括适配航司协议单元141、转发请求单元142、接收响应单元143、适配为内部模型单元144和基础数据补充单元145。适配航司协议单元141用于将系统内部模型的任务数据转换为适配于任务相对应的航空公司的协议的数据。请求单元用于将航空公司发出查询请求,并将转换后的数据传输 给航空公司。接收响应单元143用于接收航空公司根据任务数据所反馈的航班信息。适配为内部模型单元144用于将航空公司的航司协议所对应的航班信息转换为系统内部模型所适配的数据。基础数据补充单元145用于对转换后的航班信息进行补充,并将补充后的航班信息数据反馈给搜索集群13。
搜索集群13还包括更新缓存模块135和数据合并模块136,更新缓存模块135用于将补充后的航班信息存储到运营管理平台1的数据库内,便于用户查询。数据合并模块136用于将不同航空公司反馈的数据信息进行统一规划处理,便于用户查看。
参照图1和图3,交易集群12用于负责交易记录、支付、出票、订单查询等业务。交易集群12接收的任务仅针对于一家航空公司,因此交易集群12会直接将任务传输给接入集群,从而通过航空公司的反馈得知交易信息。
接入网关模块11还包括适配NDC协议模型单元114,适配NDC协议模型单元114用于将适配内部模型单元113的数据转换为适配NDC协议的数据。从而使得用户无需升级系统,即可很方便的查询所需的航班信息。对不同航空公司的数据进行同一处理,提高数据获取的速度和便捷性。
下面结合一种基于NDC的航司数据处理的系统对一种基于NDC的航司数据处理的方法的实施进行详细说明:
参照图4,本申请另一实施例提供一种基于NDC的航司数据处理的方法,包括以下步骤:
S10,接收用户请求并对用户请求进行权限、流量控制;
其中,用户端可以访问的航空公司不同,并且在接收用户端请求时,需要控制进入运营管理平台内的请求数量,从而尽量避免请求信息过多造成服务器卡死的情况发生。
在一个实施例中,用户端发出一个请求,请求内容为查询国航、南航和东航10月1号上海到北京的航班。首先判定用户端是否有查询国航航班/南航航班/东航航班的权限,判定结果为用户端能够查询国航和南航的航班,无法查询东航的航班,则生成两个任务。任务一传输给国航,内容为查询10月1号上海到北京的航班;任务二传输给南航,内容为查询10月1号上海到北京的航班。
在实施中,预设运营管理平台1所能同时处理的任务量,对运营管理平台1内的流量进行限制,从而有效避免同一时间段内运营管理平台1的任务量过大导致数据丢失的情况发生。
S20,将用户端发送的NDC请求协议转换为系统内部模型;
参照图5,将用户端发送的NDC请求协议转换为系统内部模型的具体步骤包括:
S201,对用户端的请求进行解析,获取请求项;
S202,根据请求项选取出包含获取的请求项所对应的所有航班信息。
通过对用户端发出的NDC请求协议转换成系统内部模型,从而使得将用户端发出的请求转换成适用于不同航司的通用数据,从而便于获取不同航司的信息,用户无需进行系统升级即可获取想要的数据。
在一个实施例中,用户端发出一个请求,请求内容为查询10月1号上海到北京的航班。其中,用户端采用的协议中,查询10月1号上海到北京的航班的信息通过XML的格式表示。运营管理平台1内的查询10月1号上海到北京的航班的信息通过POJO格式表示。即将用户端表示任务信息的XML格式转换为POJO格式,两个格式对应的任务信息均为查询10月1号上海到北京的航班。具体的,POJO对象中包含出发机场(上海)、回程机场(北京)、出发日期(10月1号)、返程日期、行程类型。运营管理平台通过收集用户端的信号从而获取具体的请求信息,并对请求信息进行分析,将交易请求发送给交易集群,将搜索请求发送给搜索集群。
S30,通过负载策略将用户请求发送给搜索集群13或交易集群12;
其中,负载策略为通过轮询算法达到负载均衡的一种策略。具体的,请求任务到达后,将用户端发送到负载均衡模块的请求依次轮流地转发给后端服务集群的某个节点,具有实现简单,每个集群节点平均分担所有请求的特点。
在一个实施例中,运营管理平台1同时获取了二十个任务请求,运营管理平台1内的交易集群12包含3个交易核心服务节点,运营管理平台1内的搜索集群13包含3个搜索核心服务节点。二十个任务请求中有8个是交易请求,有12个是搜索请求。其中,8个交易请求依次轮流的转发给3个交易核心服务节点,12个搜索请求依次轮流的转发给3个搜索核心服务节点。通过负载均衡的方式对请求进行处理,具有实现简单,使得每个集群节点平均分担所有请求的特点,减小了服务器的压力,提高了数据传输的速度。
S40,结合用户请求的参数将请求任务拆分为多个任务并将任务分发到航司接入服务集群14进行数据获取;
在实施中,运营管理平台1会接收到很多任务,其中包含很多无用的任务,因此需要对任务进行筛选,尽可能避免航空公司接收到无用的任务,参照图6,具体步骤如下:
S401,结合用户请求的参数将请求任务拆分为多个任务;
S402,对无效任务进行过滤;
无效任务为运营管理平台1判断出的不存在的任务,例如:查询已经售空的机票、查询航空公司没有的班次等。
S403,优先进行缓存命中;
其中,用户端访问加速节点时,如果该节点有缓存住了要被访问的数据时就叫做命中,如果没有的话需要回原服务器取,就是没有命中。取数据的过程与用户访问是同步进行的,因此即使是重新取的新数据,用户也不会感觉到有延时。命中率的计算公式为:命中率=命中数/(命中数+没有命中数)。缓存技术应用主要为提高查询速度、拦截重复请求、降低查订比。
S404,将缓存击穿的任务分发到航司接入服务集群14进行数据获取。
基于用户请求中的参数信息或任务拆分结果进行任务分发,参数信息包括航班时间、航班班次、航班票价、航班起始地和航班到达地等,任务拆分结果包括任务过滤结果、缓存命中结果等。
在一个实施例中,用户请求的参数为10月1号至10月3号期间上海到北京的航班信息。将用户请求分为三个任务,任务一为查询10月1号上海到北京的航班信息,任务二为查询10月2号上海到北京的航班信息,任务三为查询10月3号上海到北京的航班信息。其中10月1号上海到北京的航班已经售罄,则自动过滤任务一。对任务二和任务三进行缓存命中,判断任务二和任务三是否为重复请求。当判定任务二和任务三为可执行任务时,将任务二和任务三分发到航司接入服务集群14进行数据获取。
在实施中,对无效的任务进行筛并及时拦截,可以尽量避免无效的任务派发给航空公司,导致航空公司所需处理的任务过多的情况发生。
S50,按各航司协议进行参数整合发起查询请求;
参照图7,按各航司协议进行参数整合发起查询请求具体包括以下步骤:
S501,对响应数据进行解析;
在一个实施例中,运营管理平台1解析的任务内容为查询南航10月1号上海到北京的航班,任务数据在运营管理平台1内通过POJO格式表示。通过运营管理平台1上的航空公司自有接口协议15将POJO格式的任务内容转换成适用于南航协议的数据,从而获取南航10月1号上海到北京的航班的具体信息。
S502,对差异数据进行补充、标准化;
S503,将处理后的数据转换为内部结构响应给搜索集群13。
在一个实施例中,南航公司提供的10月1号上海到北京的航班的信息内容为航班时间、航班对应的票价、航班班次、航班准时率、燃油附加费和剩余座位信息,且上述信息都是由南航公司协议的对应的数据所表示。南航公司通过接口将信息反馈给航司接入服务集群14,并将信息转换成系统内部模型所适配的数据,即以POJO的格式展示。
在另一个实施例中,航司接入服务集群14获取的POJO格式的数据有缺失,对数据进行分析后发现航司接入服务集群14获取的数据缺少航班对应的航空公司的名称和航班所在的机场名称。航司接入服务集群14将数据对应的航空公司名称和机场名称以POJO格式对数据进行补充,使得数据更加完整。
S60,对数据进行缓存、聚合操作后响应上游应用;
不同航空公司提供的数据内容不同,运营管理平台1在获取不同航空公司的航班信息后,需要对航班信息的数据进行统一处理,便于用户的购票体验。
在一个实施例中,用户搜索国航、南航和东航10月1号上海到北京的航班。其中,国航提供的信息顺序为航班时间、航班对应的票价、航班班次、航班准时率、燃油附加费和剩余座位信息,南航提供的信息顺序为航班对应的票价、航班班次、航班准时率、燃油附加费、航班时间和剩余座位信息。收集到信息后,按照时间顺序对航班信息进行排序,并且以航班时间、总票价、航班班次、剩余座位信息和航班准时率的顺序对数据进行重新排序。总票价为航班对应的票价和燃油附加费的总和。
S70,将系统内部模型转换成NDC协议并响应给用户。
在一个实施例中,运营管理平台1所需反馈给用户端的数据为查询10月1号上海到北京的航班。其中,用户端采用的协议中,查询10月1号上海到北京的航班的信息通过XML的格式表示。运营管理平台1内的查询10月1号上海到北京的航班的信息通过POJO格式表示。即将运营管理平台1表示任务信息的POJO格式转换为XML格式,两个格式对应的任务信息均为查询10月1号上海到北京的航班。用户端在接收到反馈信息后会将所有的10月1号上海到北京的航班信息显示给用户进行选择。
在另一个实施例中,搜索集群13将航空公司反馈的任务信息和航班信息传输给接入网关模块11,接入网关模块11进行数据埋点,接入网关模块11对用户的浏览/查询/交易的行为进行统计。具体的,统计用户浏览的时间、统计用户查询航班的次数、统计用户购买机票的情况等。通过统计上述信息,计算出查订比,根据查订比可以做问题排查,从而对系统进行优化改善。
参照图1和图8,用户端将NDC请求发送给接入网关模块11,接入网关模块11通 过对NDC请求进行权利鉴定和流量控制后,将NDC转换成适配于系统内部模型的任务数据并传输给搜索集群13。搜索集群13将任务进行拆分缓存,并将处理好的任务分配给相应的航司接入服务集群14,航司接入服务集群14将任务以适配于相应航司协议的方式传输给相应的航空公司,并得到航空公司反馈的航班信息。航司接入服务集群14对将航班信息传输给搜索集群13,搜索集群13对接收的航班信息进行缓存聚合后传输给接入网关模块11进行埋点,并将航班信息以适配NDC协议的方式反馈给用户端。
本申请实施例提出了一种更为高效、便捷的数据直连方式,通过对航空公司数据接口采用NDC标准协议进行改造,同时对原有非标准协议航司进行聚合并采用标准化协议输出。通过集群缓存、异步化的处理方式,提高了资源获取效率,基于NDC标准协议并且对全航司数据进行整合极大的节约了用户开发维护的成本,通过采用分布式无状态架构,支持集群规模的伸缩、支持上游航司持续增加。
