Description

一种实现内容下载的方法及系统
技术领域
本发明涉及移动互联网技术领域， 尤其涉及一种实现内容下载的方法及 系统。
背景技术
随着 3G (第三代移动通信技术）网络的蓬勃发展， 移动互联网已经深入 了人们的生活。 手机阅读、 动漫平台、 游戏平台和下载平台等业务都为用户 提供了的各种形式的下载业务功能， 比如： 用户下载动漫平台的漫画到手机 客户端进行离线观看， 用户下载游戏平台的安装包进行安装。 为了促进业务 的蓬勃发展， 运营商也釆用了多种方式促进用户的下载消费行为， 如允许用 户推荐下载、 用户赠送下载、 用户通过管理员 WAP (无线应用协议）智能营 销短信下载和用户短信点播下载等。
在上述各种形式的下载方式中， 最终实现下载功能的是下载引擎。 一般 步骤为： 推荐用户将指向下载引擎文件的链接发送给被推荐的终端用户 , 或 者赠送用户将指向下载引擎文件的链接发送给被赠送的终端用户， 或者管理 员用户将指向下载引擎文件的链接发送给终端用户， 然后终端用户点击链接 进行下载。 用户可以通过 WEB (网页） 、 WAP和短信门户等进行推荐或者 赠送， 管理员可以通过管理员门户使用 WAP PUSH (推）短信智能营销。
目前是将指向下载引擎的链接发送给终端用户， 而直接将实际 URL (统 一资源定位符）发送给用户， 将会带来以下问题：
( 1 )存在盗链漏洞。 指向下载引擎的 URL链接携带了下载文件的信息、 SP (服务提供商）的信息、 CP (内容提供商） 的信息和渠道商的信息等。 如 果是赠送或者推荐下载， URL还携带了推荐或者赠送用户的信息。 这将会对 系统的安全带来很大的隐患， 而且一旦这些信息被一些非法的 SP、 CP厂商 或个人恶意利用， 会扰乱正常的下载功能并给他人造成损失。
( 2 )如果是管理员通过 WAP PUSH短信进行智能营销， 或者终端用户 通过 WAP PUSH短信进行推荐、 赠送下载或者点播下载， 由于 URL链接携 带了大量的信息， 因此长度也很大， 加上其他内容， 则该 WAP PUSH短信可 能会超过一条短信的长度， 而且在用户的终端上显示起来是一长串字母， 可 能分为很多行， 显示效果很差， 这对于注重用户体验的移动互联网业务来说 是致命的弱点。
发明内容
本发明目的是提供是一种实现内容下载的方法及系统， 解决内容下载中 的盗链及链接地址过长的问题。
为解决上述技术问题， 本发明的一种实现内容下载的方法， 包括： 门户站点在接收到触发下载的请求后， 为将被下载的内容生成伪统一资 源定位符 (URL),建立所述伪 URL与所述内容的真实 URL之间的对应关系信 息， 并将所述伪 URL发送给要下载内容的终端；
所述要下载内容的终端根据所述伪 URL将下载触发到下载引擎； 以及 所述下载引擎根据所述伪 URL查询所述伪 URL与所述内容的真实 URL 之间的对应关系信息， 获取所述内容的真实 URL, 并根据获取到的真实 URL 将内容下载到所述要下载内容的终端。 所述伪 URL包含所述下载引擎的地址和内容相关信息的标识码。

图 2为本发明实施方式的实现内容下载的系统的架构图；
图 3为本发明实施方式中实现推荐下载内容的流程图；
图 4为本发明实施方式中实现点播下载内容的流程图。 本发明的较佳实施方式
本实施方式中向要下载内容的终端发送的 URL链接不再是真正的 URL, 而是由 WEB门户、 WAP门户、 短信门户或管理员门户生成的伪 URL。 同时 各个门户站点在数据库中记录该伪 URL和真正的 URL的对应关系信息。 当 有终端进行推荐、 赠送、 短信点播或者管理员智能营销时， 将伪 URL发送给 要下载内容的终端， 要下载内容的终端点击伪 URL链接时， 重定向到下载引 擎， 下载引擎到数据库查询该伪 URL和真实 URL的对应关系， 获取真正的 URL, 并对真正的 URL进行解析， 触发计费业务， 计费业务对用户的下载行 为进行鉴权并计费。 鉴权或者计费成功后返回下载引擎成功消息， 由下载引 擎进行下载处理， 允许或者拒绝用户进行文件的下载。
本实施方式还公布了一种下载系统， 该系统包括： 门户站点、 数据库， 下载引擎以及鉴权扣费实体， 其中， 门户站点包括 WEB门户、 WAP门户、 短信门户和管理员门户等， 能够按照一定的规则生成伪 URL; 数据库记录伪 URL和真实 URL的对应关系信息； 下载引擎根据伪 URL查询对应的真实 URL, 解析真实 URL并触发鉴权扣费实体； 鉴权扣费实体对要下载内容的终 端的下载请求进行鉴权， 如果鉴权通过则向下载引擎返回消息， 由下载引擎 进行下载操作。 下面结合附图对本实施方式的方法及系统进行详细说明。
实施例 1:
图 1所示为本实施方式的实现内容下载的方法， 包括如下步骤：
S101: 在数据库中建立供下载的内容（简称内容）的真实 URL和伪 URL 的对应关系信息表， 并配置伪 URL的失效时间项；
S102: 门户站点在接收到触发下载的请求后，为下载的内容生成伪 URL, 并将伪 URL和所对应的真实 URL在数据库中的对应关系信息表中进行记录， 同时记录伪 URL的失效时间；
对于不同的门户站点， 处理方式如下所述：
推荐用户通过 WEB门户或 WAP门户等推荐下载内容， WEB门户或 WAP 门户生成伪 URL, 并将伪 URL和所对应的真实 URL在数据库中的对应关系 信息表中进行记录， 同时记录伪 URL的失效时间；
推荐用户也可以通过 WEB门户或 WAP门户赠送下载内容， WEB门户 或 WAP门户生成伪 URL, 并将伪 URL、 所对应的真实 URL和伪 URL的失 效时间在数据库中的对应关系信息表中进行记录。
要下载内容的终端可以通过短信门户点播下载内容； 短信门户生成伪 URL , 并将伪 URL、 所对应的真实 URL和伪 URL的失效时间在数据库中的 对应关系信息表中进行记录。
管理员进行短信营销推荐时， 管理员门户生成伪 URL, 并将伪 URL、 所 对应的真实 URL和伪 URL的失效时间在数据库中的对应关系信息表中进行 记录。
S103: 门户站点将伪 URL发送给要下载内容的终端；
伪 URL包含下载引擎的地址和内容相关信息的标识码。
S104: 当要下载内容的终端点击伪 URL链接进行下载操作时，根据用户 的赠送、 推荐、 营销短信的伪 URL的链接， 定向到下载引擎， 下载引擎到数 据库根据伪 URL查询真实 URL; 要下载内容的终端根据伪 URL中包含的下载引擎的地址，将下载触发到 所述下载引擎， 使下载引擎获取到内容的伪 URL。
S105:下载引擎对真实 URL进行解析，并通过计费鉴权接口将真实 URL 发送给鉴权扣费实体， 向鉴权扣费实体发起计费鉴权请求；
真实 URL包含内容相关信息， 内容相关信息包括： 内容的地址及内容的 信息 +SP的信息 +CP的信息 +推荐操作的标志 +用户 A的用户 ID+用户 B的用 户 ID等。
S 106： 鉴权扣费实体根据内容相关信息对要下载内容的终端的下载进行 鉴权， 并将鉴权结果返回给下载引擎， 下载引擎根据鉴权结果进行下载处理； S107: 当终端成功下载文件后， 下载引擎触发鉴权扣费实体， 鉴权扣费 实体进行计费处理， 并将伪 URL对应的记录删除；
当超过伪 URL的失效时间后， 由专门的任务删除上述的伪 URL所对应 的记录。
优选地， 为了保证数据库中失效的伪 URL及时删除， 数据库表结构增加 记录失效时间的字段， 数据库表结构可以设计如下：
Figure imgf000008_0001
当下载引擎判断用户使用伪 URL进行下载成功之后，下载引擎触发鉴权 扣费实体， 鉴权扣费实体进行计费的同时， 删除数据库中的对应记录； 或者 在超过失效时间后如果还没有下载， 则由任务删除该记录。
在步骤 S102中， 4叚设用户 A向用户 B推荐下载内容， 为了能够标识推 荐用户推荐的内容， 统计 SP和 CP的累计下载量， 同时也为了保证只有接受 推荐的用户才能下载内容等，门户站点需要将下载引擎的地址 +内容相关信息 送给下载引擎，由下载引擎将上述信息送给鉴权扣费实体或者其他计费网元， 完成鉴权和计费等操作。 内容相关信息包括： 内容的地址及内容的信息 +SP 的信息 +CP的信息 +推荐操作的标志 +用户 A的用户 ID+用户 B的用户 ID等， 其中， 用户 B是接受推荐的用户， 也就是要下载内容的用户。 由于包含了要 下载内容的用户的信息， 该消息被转发后， 到鉴权扣费实体进行鉴权时如果 赠送用户和接受用户的对应关系错误， 此下载行为将被拒绝。
在本实施例中， 将需要隐藏的内容相关信息， 比如内容的地址及内容信 息、 SP的信息、 CP的信息、 推荐操作的标志、 用户 A的用户 ID和用户 B 的用户 ID等用一字符串来替代， 该字符串可以称为内容相关信息的标识码， 该内容相关信息的标识码拼接在下载引擎的地址之后， 形成用户下载操作的 伪 URL。
更进一步的， 上述的内容相关信息的标识码可以釆用多种方式生成， 但 是要保证每个下载行为对应的字符串必须唯一。 优选地， 可以釆用时间戳 + 消息源的网元编号 +随机数字的方式。 其中， 时间戳可以精确到秒。 消息源的 网元编号指的是 WEB门户、 WAP门户、 短信门户和管理门户等的编号。 比 如 WEB门户是 001 , WAP门户是 002、 短信门户是 003、 管理门户是 004。
当用户进行推荐、 赠送、 短信点播、 管理员营销的时候， 发送给终端用 户链接的方式包括如下：
站内消息， 适用于 WEB、 WAP门户的推荐、 赠送操作和管理员的智能 营销。
邮件发送， 适用于 WEB、 WAP门户的推荐、 赠送和管理员的智能营销。
PUSH短信发送， 适用于 WEB、 WAP门户的推荐、 赠送和管理员的智能 营销和用户短信门户点播操作。
实施例 2:
如图 2所示， 本实施方式的系统包含： 门户站点、 数据库、 下载引擎和 计费鉴权实体， 其中， 门户站点包含 WEB门户、 WAP门户、 短信门户和管 理门户等。
WEB 门户： 提供用户用 PC接入系统的操作界面和功能， 用户可以在 WEB门户上面通过站内消息、 邮件和 push短信等方式给其他用户进行推荐、 赠送等操作。 在用户进行推荐、 赠送的时候， WEB门户生成伪 URL, 并记录 到数据库。
WAP门户： 提供用户用移动终端接入系统的操作界面和功能， 用户可以 在 WAP门户上面通过站内消息、 邮件和 push短信等方式给其他用户进行推 荐、 赠送等操作。 在用户进行推荐、 赠送的时候， WAP门户生成伪 URL, 并 记录到数据库。
短信门户： 用户可以发送特定的字符串到短信门户的接入码， 以接入短 信门户， 实现短信点播功能。 比如用户编辑 download gamel , 发送到接入码 12345678。 短信门户收到消息后， 返回用户含有伪 URL的 push短信链接， 并在数据库记录伪 URL和真实 URL的对应关系。 当用户点击该链接的时候， 则下载 gamel。
管理门户： 本实施例中， 管理员通过管理门户进行智能营销， 管理员通 过管理门户编辑包含伪 URL的站内消息、 邮件和 push短信等发送给要下载 内容的终端， 并将 URL和真实 URL的对应关系记录在数据库。 终端用户通 过点击该伪 URL, 实现下载的功能。
数据库： 记录用户的基本信息、 账户信息、 消费记录、 内容的真实 URL 和伪 URL的对应关系信息等。
下载引擎： 实现真实 URL和伪 URL的对应关系查询， 解析真实 URL, 触发计费鉴权业务， 用户下载管理等功能。
计费鉴权实体： 实现用户下载行为的鉴权和计费功能， 对成功下载的真 实 URL和伪 URL的对应关系进行删除。
实施例 3:
如图 3所示， 以用户 A通过 WEB门户向用户 B推荐下载内容的流程为 例， 对本实施方式的实现内容下载的方法进行说明， 包括：
S301 : 用户 A在 WEB门户发起推荐操作， 选择推荐内容， 填写推荐的 用户信息， 提交到 WEB门户；
S302: WEB门户生成推荐内容的伪 URL,并将真实 URL和伪 URL提交 给数据库； S303:数据库记录真实 URL和伪 URL的对应关系信息及记录失效时间， 并返回记录成功消息到 WEB门户；
S304: WEB门户通知用户 B: 用户 A推荐下载内容给用户 B, 消息携带 伪 URL;
S305: WEB门户提示用户 A推荐成功；
S306: 用户 B看到用户 A推荐的内容后， 点击伪 URL的链接， 进行下 载操作；
S307: 下载引擎收到下载请求后， 根据伪 URL到数据库查询真实 URL 及失效时间；
S308: 数据库返回真实 URL及失效时间；
S309: 下载引擎解析真实 URL, 并通过与鉴权计费实体的接口将真实 URL发送给鉴权计费实体， 触发计费鉴权；
S310: 鉴权计费实体根据真实 URL对下载行为进行鉴权， 判断是否允许 下载， 并将鉴权结果送给下载引擎；
S311 : 下载引擎判断鉴权结果， 允许下载则进行下载处理；
S312: 用户 B的下载处理；
S313: 下载引擎判断下载操作是否成功， 若成功则再次触发鉴权计费实 体， 进行计费确认；
