  • the present invention relates to network data communication technologies, and in particular, to a sharing control system and method for downloading network resource information.
  • Network resources generally refer to digital resources stored on the network for download by netizens, including: program files, video files, audio files, and so on.
  • the current common ways to download network resources include the following:
  • Point-to-server technology P2S, Peer to Server
  • all network resources are stored in a server of a large download website, and the user directly downloads the resource file to the download website, and the download speed of the method can be obtained. Guaranteed, but resources are scattered and not easy to search.
  • Peer-to-Peer also known as peer-to-peer technology. This technique relies on network resources to download the computing power and bandwidth of the participant's devices, rather than focusing on a small number of servers.
  • P2P technology has been widely used in file sharing and downloading. The download speed of the P2P end is closely related to the upload speed of the other end. Since most Chinese users use ADSL to access the Internet, the upload speed of ADSL is not fast. Only a few tens of K speed, some users will artificially limit the upload speed, which leads to the P2P mode. The lack of upload bandwidth resources, so users will generally feel that P2P is slower.
  • P2SP Point-to-server and peer
  • P2SP Peer to Server&Peer
  • P2SP also includes the server, which is the "S" of P2SP.
  • P2SP effectively integrates isolated servers with their mirrored resources and P2P resources. It has a much higher improvement in download stability and download speed than traditional P2P or P2S.
  • P2SP is based on user-to-server and user mechanism. It is different from P2P and P2S. It not only supports P2P technology, but also integrates server resources and P2P resources by searching the database. When users download a file, they will automatically search for other files. Resources, choose the right resources to accelerate, which makes p2sp very large in the stability of download and download speed than traditional P2P Lift! 3 ⁇ 4.

Description

网络资源下载信息的分享控制系统和方法 技术领域
本发明涉及网络数据通信技术, 尤其涉及一种网络资源下载信息的分享 控制系统和方法。
背景技术
网络资源一般是指存储在网络上供网民下载使用的数字化资源, 包括: 程序文件、 视频文件、 音频文件等。 目前下载网络资源的常用方式包括以下 几种:
(一)点对服务器技术(P2S, Peer to Server ) , 所有的网络资源都存储 在某个大型下载网站的服务器中, 用户直接到该下载网站去下载资源文件, 该种方式的下载速度可以得到保证, 但资源分散、 不易搜索。
(二) 点对点技术(Ρ2Ρ, Peer-to-Peer ) , 又称为对等技术。 这种技术 依赖网络资源下载参与者设备的计算能力和带宽, 而不是把依赖都聚集在较 少的几台服务器上。 P2P技术在文件共享和下载方面得到了广泛的应用。 P2P 一端的下载速度和另一端的上传速度密切相关, 由于中国用户大多使用 ADSL上网, ADSL的上传速度并不快, 仅几十 K速度, 一些用户还会人为 限制上传速度, 这导致了 P2P方式的上传带宽资源的缺乏, 因此用户会普遍 感觉 P2P的速度较慢慢。
(三)点对服务器和点(P2SP, Peer to Server&Peer )技术, 就是下载不 再象传统方式那样只能依赖服务器, 内容的传递可以在网络上的各个终端机 器中进行。 P2SP除了包含 P2P以外, 还包括服务器, 即 P2SP的 "S" 。 P2SP 有效地把原本孤立的服务器和其镜像资源以及 P2P资源整合到了一起。 它在 下载的稳定性和下载的速度上, 都比传统的 P2P或 P2S有了非常大的提高。 P2SP基于用户对服务器和用户机制, 不同于 P2P, 也不同于 P2S, 它不但支 持 P2P技术,同时还通过检索数据库把服务器资源和 P2P资源整合到了一起, 用户下载一个文件的时候,会自动搜索其他资源,选择合适的资源进行加速, 这使得 p2sp在下载的稳定性和下载的速度上, 比传统的 P2P有了非常大的 提! ¾。
在 P2SP技术当中, 下载一个网络资源文件, 数据来源分为源下载链接、 P2P网络、 第三方镜像的辅助源, 然后通过完整文件的唯一标识, 比如通过 消息摘要算法第五版(MD5 )或者安全散列算法(SHA )计算得到的唯一标 识, 把文件统一串联起来。 图 1为现有的 P2SP技术中网络资源分享和下载 的具体控制流程图。 参见图 1 , 所述 P2SP网络中包括下载客户端、 资源索引 服务器、 Tracker服务器、 以及统计服务器。
所述下载客户端主要用于: ( 11 )定期向 Tracker服务器汇报在线情况 和本地拥有的资源信息; (12 )通过源 URL向资源索引服务器查询多资源 URL集合、 HASH及文件校验信息, 从 URL集合源下载数据; (13 ) 同时 向 Tracker服务器查询种子( Peer ); ( 14 )完成下载任务后, 向统计服务器 汇报本次下载任务的下载时间、 下载速度、 下载结果、 文件大小, 下载的源 链接和不同 URL 源获取的下载速度和下载时间; (15 ) 下载过程当中发现 下载到完成的数据分片后, 进行校验, 如果发现分片错误, 向统计服务器上 报。
所述资源索引服务器主要用于: (21 )接收客户端通过 URL作为索引 的入口查询文件 HASH; ( 22 )接收客户端通过 URL作为索引的入口查询 下载的多 URL资源集合; (23 )提供文件分片校验信息, 供下载客户端校 验下载数据的有效性。
所述 Tracker服务器用于: (31 ) 为每个申请加入网络的客户端提供注 册, 并反馈其所拥有该资源节点的 IP地址列表; (32 )接收客户端的在线情 况汇报, 生成各资源的节点列表并在有节点申请下载该任务时进行反馈; ( 33 )接收带宽调度服务器同步的 Peer在线控制策略, 在 Peer登陆的时候 下发到 Peer客户端。
所述统计服务器用于: 接受客户端的下载完成和下载过程中 URL下载 速度, 下载时间, 连通情况, 下载结果, 文件大小等信息的上 ·¾, 并写成流 水日志的方式供后续统计分析。
参见图 1 , P2SP网络中, 网络资源的下载流程主要包括: (1 )用户需 要下载网络资源的时候从互联网或者资源网站获取原始 URL链接。 (2 )用 户以原始 URL链接为入口, 从资源索引服务器查询多资源 URL集合及文件 哈希( HASH )值。 ( 3 )下载客户端从查询到的 URL下载数据。 ( 4 )下载 完成后注册文件信息到 Tracker服务器。 ( 5 )其他客户端可以通过 Tracker 服务器查询到 P2P种子, 即已经下载完成的种子(Peer )和正在下载的 Peer。 ( 6 )其它下载客户端开始查询多源 P2P下载, 在 Peer之间相互交换数据。 ( 7 ) 下载完成以后将相关的统计信息上报给统计服务器。
不论上述哪种下载技术, 首要问题是将网络资源的下载信息, 主要是源 下载链接地址, 发布分享出来, 供大家访问下载。 目前, 这些网络资源的下 载信息主要通过以下几种方式进行分享发布:
( a )在下载网站或者网络论坛上直接发布, 下载用户可以从下载网站 或网络论坛上获取网络资源的源下载链接地址。
( b )接受用户通过各种网络即时通讯系统传递和分享网络资源下载的 源下载链接地址。
( c )利用微博客 ( MicroBlog )分享网络资源的源下载链接地址。
其中, 上述利用微博客分享网络资源的下载信息是目前的一种最新技 术, 也是一种最新趋势。
微博客, 筒称微博, 是一个基于用户关系的信息分享、 传播以及获取的 网络平台, 用户可以通过有线通信网络或无线通信网络、 以及各种客户端访 问微博, 以指定数目的文字(例如通常为 140字左右)和 /或其它多媒体信息 更新信息, 并实现即时分享。 微博将手机短信、 社交网站、 博客等媒体捆绑 起来, 强化了微博与各媒介之间的纽带关系, 使得信息能在更大范围内得以 共享, 微博正在以非常快的速度成为网民信息传播的首选方式, 并极有可能 从根本上改变网络用户的信息访问轨迹, 成为用户进入网站了解各类信息的 新入口, 更是门户网站吸引用户、 留住用户的新工具。
随着微博的迅猛发展, 各大平台也开始开放, 开放成为互联网的主流。 微博开放平台是一个基于微博客系统的开放的信息订阅、 分享与交流平台。 微博现有的用户传播体系非常完整, 好友之间通过大量的信息分享带来裂变 式的传播。 平台提供了分享按钮和动态展现插件, 可以让合作系统方仅仅通 过几行 HTML代码就能够在其自己的网站上加入 專社交特性,分享的内容 也会在微博网站上展现, 用户点击链接后可直接进入相关内容。 微博上能够 分享供下载的内容也越来越多了 ,也提供了大量的 API接口帮合作系统方实 现更多的特性。 目前很多用户喜欢将新的网络资源分享到微博平台。
鉴于 專的上述特点, 目前 專已经成为一个网络资源下载信息分享和 传播的一个重要平台。
但是, 现有的利用微博分享网络资源下载信息的方式存在以下缺陷: 目前微博开通的多种应用程序编程接口 (API )使得大量的用户可以通 过手机、 网络等方式更新微博信息, 信息能够快速传播, 这样方便了一些具 有非法内容的网络资源的下载和传播。 但是, 目前利用微博进行网络资源下 载信息的分享方式并没有对下载信息的传播风险进行控制, 无法对网络资源 的下载信息进行审计和追溯, 无法控制非法信息的分享和传播。
发明内容
有鉴于此, 本发明的主要目的在于提供一种网络资源下载信息的分享控 制系统和方法, 以有效控制网络资源下载信息的传播风险。
本发明的技术方案是这样实现的:
一种网络资源下载信息的分享控制系统, 包括:
微博分享接口服务器, 用于接收来自客户端的分享网络资源的指令, 获 取由该网络资源的源下载链接地址计算得到的唯一标识; 生成对应的携带所 述唯一标识的、 且指向中转服务器的下载链接入口地址, 将该下载链接入口 地址发布到微博中; 并将该网络资源的唯一标识存储在分享资源数据库中; 分享资源数据库, 用于存储所分享网络资源的唯一标识, 并设置网络资 源对应的下载控制条件;
中转服务器, 用于响应所述微博中下载链接入口地址的被点击事件, 根 据被点击的下载链接入口地址中的唯一标识从分享资源数据库中查询对应 网络资源的下载控制条件, 根据该下载控制条件判断是否允许下载, 在允许 下载的情况下, 以所述唯一标识反向计算得到该网络资源的源下载链接地 址, 将该源下载链接地址发送给点击所述下载链接入口地址的客户端。 一种网络资源下载信息的分享控制方法, 包括:
接收分享网络资源的指令, 获取并存储由该网络资源的源下载链接地址 计算得到的唯一标识; 生成该网络资源对应的携带所述唯一标识的下载链接 入口地址, 将该下载链接入口地址发布到 博中; 设置该网络资源对应的下 载控制条件;
在所述微博中的下载链接入口地址被点击后, 根据其中的唯一标识查询 对应网络资源的下载控制条件, 根据该下载控制条件判断是否允许下载, 在 允许下载的情况下, 以所述唯一标识反向计算得到该网络资源的源下载链接 地址, 将该源下载链接地址发送给点击所述下载链接入口地址的客户端。
与现有技术相比, 本发明所在微博中发布的并不是可以直接访问到网络 资源的源下载链接地址, 而是一种下载链接入口地址, 通过点击该下载链接 入口地址会触发下载控制鉴权,只有符合下载控制条件才会允许下载, 因此, 本发明可以根据控制需求, 有效地控制网络资源下载信息的传播风险, 尤其 可以有效地控制非法信息的分享和传播风险。
上述说明仅是本发明技术方案的概述, 为了能够更清楚了解本发明的技 术手段, 而可依照说明书的内容予以实施, 并且为了让本发明的上述和其它 目的、 特征和优点能够更明显易懂, 以下特举实施例, 并配合附图, 详细说 明如下。 附图概述
图 1为现有的 P2SP技术中网络资源分享和下载的具体控制流程图; 图 2 为本发明所述网络资源下载信息的分享控制系统的一种组成示意 图;
图 3为本发明所述网络资源下载信息的分享控制系统应用在 P2SP下载 平台中的一种组成示意图。
本发明的较佳实施方式 以下结合附图及较佳实施例 , 对依据本发明提出的网络资源下载信息的分享 控制系统和方法的具体实施方式、 结构、 特征及其功效, 详细说明如下: 有关本发明的前述及其它技术内容、 特点及功效, 在以下配合参考图式 的较佳实施例的详细说明中将可清楚呈现。 通过具体实施方式的说明, 当可 了解,然而所附图式仅是提供参考与说明之用,并非用来对本发明加以限制。
图 2为本发明所述网络资源下载信息的分享控制系统的一种实施例组成 示意图。 参见图 2, 该分享控制系统包括微博分享接口服务器 201、 分享资 源数据库 202、 以及中转服务器 203。
微博分享接口服务器 201封装有可供客户端调用的微博分享接口, 该微 博分享接口用于接收来自分享客户端 200的分享网络资源的指令, 并获取由 该网络资源的源下载链接地址计算得到的唯一标识, 具体的获取方式可以是 通知分享客户端 200在客户端本地计算或从资源提供方获取该网络资源的源 下载链接地址的唯一标识。 此处所述客户端例如可以计算机、 手机、 平板电 脑的浏览器, 或者其他客户端如微博客户端, 下载工具客户端等。
所述网络资源的源下载链接地址的唯一标识, 是指网络资源的文件 ID, 又叫做 HASH值, 这是下载链接里面的关键信息。 4艮多文件即使它们的文件 名不一样, 但是只要 HASH值一致, 下载平台就视同为同一个文件。
所述微博分享接口服务器 201获取到所述网络资源的源下载链接地址的 唯一标识之后, 生成对应的携带所述唯一标识的、 且指向中转服务器的下载 链接入口地址, 将该下载链接入口地址发布到微博中, 并将该网络资源的唯 一标识存储在分享资源数据库中。
所述下载链接入口地址要符合微博的发布标准, 即下载链接入口地址的 长度小于微博所允许的最大信息长度(通常为 140字) , 这样就可以大大提 高利用微博发布网络资源下载信息的成功率, 并可以在中转页面提供具体分 享的内容及资源描述和源下载链接地址, 可以解决微博上 140字表现力不足 的问题。
所述分享资源数据库 202用于存储所分享网络资源的信息, 其中至少包 括网络资源的唯一标识, 还可以进一步包括网络资源的相关描述信息; 还存 储网络资源对应的下载控制条件。
中转服务器 203 , 用于响应所述微博中的下载链接入口地址的被点击事 件(即当用户利用下载客户端 210本地的浏览器在微博中浏览到所述下载链 接入口地址后, 点击该下载链接入口地址, 则该点击请求会转向该中转服务 器 203 ) , 根据被点击的下载链接入口地址中的唯一标识从分享资源数据库 202 中查询对应网络资源的下载控制条件, 根据该下载控制条件判断是否允 许下载, 在允许下载的情况下, 以所述唯一标识反向计算得到该网络资源的 源下载链接地址, 将该源下载链接地址发送给点击所述下载链接入口地址的 客户端。
在本发明中有两种发送所述源下载链接地址的方式: 一种方式是重定向 方式, 即不生成中转页面, 直接重定向源下载链接地址发送给所述点击客户 端, 该点击客户端可以使用浏览器等工具直接下载, 也可以调用专用的客户 端下载工具直接下载; 另一种方式是所述中转服务器 203进一步生成中转页 面, 将所述源下载链接地址显示在该中转页面中, 将该中转页面发送给点击 所述下载链接入口地址的客户端, 用户可以进一步点击该中转页面中的源下 载链接地址并由浏览器或对应的下载工具进行下载。
在另一种实施方式中, 该微博分享接口服务器 201的微博分享接口还可 以进一步用于接收来自分享客户端 200的对所分享网络资源的相关描述信息 (如该网络资源的名称、 文字描述或图片描述等信息) , 将该网络资源的相 关描述信息存储到所述分享资源数据库中, 并与该网络资源的唯一标识绑 定。如果所述分享资源数据库 202中进一步存储了网络资源的相关描述信息, 则所述中转服务器进一步用于根据被点击的下载链接入口地址中的唯一标 识从分享资源数据库中查询所述网络资源的相关描述信息, 生成包含所述源 下载链接地址和相关描述信息的中转页面, 将该中转页面发送给点击所述下 载链接入口地址的客户端, 用户可以进一步点击该中转页面中的源下载链接 地址并由浏览器或对应的下载工具进行下载。
本发明专注于解决网络资源下载信息的分享控制, 对于网络资源具体的 下载方式并不具体限定, 可以应用 P2S下载方式、 P2P下载方式、 P2SP下载 方式等进行下载, 不同的是: 如果网络资源需要采用 P2S下载方式下载, 则 其源下载链接地址一般是网络资源 (如某一个视频文件) 的直接下载地址, 如果网络资源需要采用 P2P或 P2SP下载方式下载, 则其源下载链接地址一 般是种子文件 (如目前业界常用的 BT种子文件或 emule种子文件等) 的直 接下载地址, 下载客户端得到该种子文件地址后, 利用对应的下载工具获取 对应的 URL地址进行下载。
下面实施例以应用在 P2SP下载网络中的场景为例, 对本发明做进一步 说明。 图 3为本发明所述网络资源下载信息的分享控制系统应用在 P2SP下 载平台中的一种组成示意图。 参见图 3 , 所述 P2SP网络中包括下载客户端、 资源索引服务器、 Tracker服务器、 以及统计服务器。 本发明所述的分享控制 系统包括微博分享接口服务器 201、 分享资源数据库 202、 以及中转服务器 203。 所述分享客户端 301 可以是下载客户端, 只不过其可以调用所述微博 分享接口服务器 201的接口进行下载信息分享, 因此在此处称其为分享客户 端。 当然所述分享客户端 301也可以是访问某资源分享网站的浏览器, 该资 源分享网站可以调用所述微博分享接口服务器 201 的接口进行下载信息分 享。 所述下载客户端可以从微博平台上获取下载链接入口地址, 并利用中转 服务器 203发送来的源下载链接地址 URL下载对应的网络资源文件, 如果 URL支持重定向就从重定向的文件下载。
参见图 3,本发明在原有的 P2SP下载平台上,增加了本发明所述的网络 资源下载信息的分享控制系统, 使原有的 P2SP下载平台和微博平台无缝整 合到一起, 发挥各自的优势。
下面以图 3所示的应用场景为例, 对本发明所述分享控制系统执行的网 络资源下载信息的分享控制方法进行说明。
本发明所述的网络资源下载信息的分享控制方法主要包括:
分享控制系统 300接收来自分享客户端 301的分享网络资源的指令, 获 取并存储由该网络资源的源下载链接地址计算得到的唯一标识; 生成该网络 资源对应的携带所述唯一标识的下载链接入口地址, 将该下载链接入口地址 发布到微博中; 设置该网络资源对应的下载控制条件。
分享控制系统 300在所述微博中的下载链接入口地址被点击后, 根据其 中的唯一标识查询对应网络资源的下载控制条件, 根据该下载控制条件判断 是否允许下载, 在允许下载的情况下, 以所述唯一标识反向计算得到该网络 资源的源下载链接地址, 将该源下载链接地址发送给点击所述下载链接入口 地址的客户端。
下面具体说明该方法的详细过程和更多的实施方式。 参见图 3, 所述分享客户端 301可以在下载网络资源的同时或之后调用微博分享接 口服务器 201的接口向微博分享接口服务器 201发出分享某网络资源(例如 某个视频文件) 的指令。
微博分享接口服务器 201接收到分享网络资源的指令后, 获取由该网络 资源的源下载链接地址计算得到的唯一标识, 此处该唯一标识是该源下载链 接地址的 HASH值,可以通过所述接口命令所述分享客户端 301查找该网络 资源的源下载链接地址并以此计算出其 HASH值,将该 HASH值上传给微博 分享接口服务器 201。微博分享接口服务器 201在获取到该网络资源的 HASH 值后, 将该 HASH值保存到分享资源数据库 202中, 并且通过分享资源数据 库 202的操作接口在分享资源数据库 202中设置该网络资源对应的下载控制 条件, 还生成该网络资源对应的携带所述 HASH值的下载链接入口地址, 将 该下载链接入口地址发布到微博平台 204中。 此处具体可以由所述微博分享 接口提示分享客户端 301输入微博帐号和密码, 并对帐号和密码进行验证, 验证通过后, 将所述下载链接入口地址发布到该微博帐号对应的微博文章 中。
到此时, 网络资源的分享操作完成, 接下来是下载控制过程。
所述下载链接入口地址被分享到微博平台后, 下载客户端 302的用户可 以利用浏览器等工具浏览相应的博文, 点击其中的下载链接入口地址, 由于 该下载链接地址指向所述中转服务器 203 , 因此中转服务器 203在所述微博 中的下载链接入口地址被点击后, 可以收到其中的 HASH值, 根据该 HASH 值从分享资源数据库 202中查询对应网络资源的下载控制条件, 根据该下载 控制条件判断是否允许下载, 在允许下载的情况下, 以所述 HASH值反向计 算得到该网络资源的源下载链接地址, 将该源下载链接地址发送给点击所述 下载链接入口地址的客户端 302。 本发明的主要目的就是根据控制需求, 有效地控制网络资源下载信息的 传播风险。 所述设置下载控制条件并进行下载控制可以有多种实施方式, 以 下主要介绍其中的四种, 其他的具体下载控制条件和控制方式可以由管理人 员根据需求自行设定。
第一种下载控制实施方式:
所述设置网络资源对应的下载控制条件具体为: 设置该网络资源对应的 有效时间; 并且, 在分享客户端 301分享所述网络资源时, 微博分享接口需 要生成时间戳, 并将该时间戳与所分享网络资源的唯一标识绑定存储在分享 资源数据库 202中。 在所述下载链接入口地址被点击后, 所述根据下载控制 条件判断是否允许下载具体为: 从分享资源数据库 202中查询所述网络资源 唯一标识对应的时间戳和有效时间, 查询当前时间是否超过该网络资源对应 的有效时间, 即当前时间减去所述时间戳是否超过所述有效时间, 如果超过 则不允许下载; 否则允许下载。
第二种下载控制实施方式: 图 3所述的 P2SP平台中, 所述统计服务器用于接受客户端的下载完成 和下载过程中 URL下载速度, 下载时间, 连通情况, 下载结果, 文件大小 等信息的上 ·¾, 并写成流水日志的方式供后续统计分析, 如对同一网络资源 的实际下载次数进行统计。
所述设置网络资源对应的下载控制条件具体为: 设置该网络资源对应的 最高下载次数。 在所述下载链接入口地址被点击后, 所述根据下载控制条件 判断是否允许下载具体为: 中转服务器 203从统计服务器获取该网络资源的 实际下载次数, 从分享资源数据库 202中查询所述网络资源唯一标识所对应 的最高下载次数, 判断该网络资源当前的实际下载次数是否超过该网络资源 的最高下载次数, 如果超过则不允许下载; 否则允许下载。
第三种下载控制实施方式:
所述设置网络资源对应的下载控制条件具体为: 利用所述微博分享接口 获取网络资源分享者的微博帐号, 并与网络资源的唯一标识绑定存储在分享 资源数据库 202中; 同时设置允许下载该网络资源的微博帐号与该分享者微 博帐号的关系链条件, 例如该关系链条件可以是: 下载者的微博帐号必须是 分享者微博帐号的 "关注人" , 所述 "关注人" 是指 "被关注人" 只要有微 博发出, 则 "关注人" 就可以即时看到。
在所述下载链接入口地址被点击后, 所述根据下载控制条件判断是否允 许下载具体为: 通过微博分享接口服务器 201从微博平台获取点击所述下载 链接入口地址的用户的微博帐号及其关系链信息, 判断该微博帐号与分享者 的微博帐号是否满足所述下载控制条件所设置的关系链条件, 如果满足则允 许下载; 否则不允许下载。 例如, 如果下载者微博帐号是分享者微博帐号的 "关注人" , 则允许下载, 否则不允许下载。
第四种下载控制实施方式:
在分享客户端 301分享所述网络资源时, 微博分享接口需要进一步计算 所分享网络资源的鉴权校验码, 将包括该鉴权校验码的下载链接入口地址发 布到微博中, 并将该鉴权校验码存储在所述网络资源对应的下载控制条件 中。
在所述微博中的下载链接入口地址被点击后, 所述根据下载控制条件判 断是否允许下载具体为: 获取该被点击下载链接入口地址中的鉴权校验码, 从分享资源数据库 202中查询所述网络资源唯一标识所对应的鉴权校验码进 行比对, 如果一致, 则允许下载; 否则不允许下载。
对于所述中转服务器 203发送所述源下载链接地址的方式,具体有两种: 一种方式是重定向方式, 即不生成中转页面, 直接重定向源下载链接地址发 送给所述下载客户端 302, 该下载客户端 302可以使用浏览器等工具直接下 载, 也可以调用专用的客户端下载工具直接下载(例如图 3所示实施例中可 以调用专用的 P2SP客户端下载) ; 另一种方式是所述中转服务器 203进一 步生成中转页面, 将所述源下载链接地址显示在该中转页面中, 将该中转页 面发送给点击所述下载链接入口地址的客户端 302, 用户可以进一步点击该 中转页面中的源下载链接地址并由浏览器或对应的 P2SP客户端进行下载。
在一种实施方式中, 该微博分享接口服务器 201的接口还可以进一步用 于接收来自分享客户端 301的对所分享网络资源的相关描述信息(如该网络 资源的名称、 文字描述或图片描述等信息) , 将该网络资源的相关描述信息 存储到所述分享资源数据库 202中, 并与该网络资源的唯一标识绑定。 如果 所述分享资源数据库 202中进一步存储了网络资源的相关描述信息, 则所述 中转服务器 203进一步用于根据被点击的下载链接入口地址中的唯一标识从 分享资源数据库 202中查询所述网络资源的相关描述信息, 生成包含所述源 下载链接地址和相关描述信息的中转页面, 将该中转页面发送给点击所述下 载链接入口地址的客户端 302, 用户可以进一步点击该中转页面中的源下载 链接地址并由浏览器或对应的 P2SP客户端进行下载。
图 3所述实施场景中, 下载客户端 302可以利用 P2SP客户端以获得的 源下载链接地址为入口, 从资源索引服务器查询多资源 URL集合以及文件 HASH值, 之后从 URL集合源(路径包括 Internet及资源网站以及其他种子 客户端)下载数据, 并注册文件信息到 Tracker服务器。 其他下载客户端 303 可以通过 Tracker服务器查询到 P2P种子, 即已经下载完成的种子和正在下 载的种子。 下载客户端 303开始查询多源 P2P种子, 在种子之间相互交换下 载数据, 从而实现 P2SP的共享下载。
图 3所述的 P2SP平台中, 所述统计服务器可记录用户的下载行为, 例 如接受客户端的下载完成和下载过程中 URL下载速度, 下载时间, 连通情 况, 下载结果, 文件大小等信息的上 ·¾, 并写成流水日志的方式供后续统计 分析, 并可以将用户下载微博链接的相关文件的名称, 下载热度和下载客户 端的 P2SP帐号等信息同步到分享资源数据库 202中。 因此, 在本发明的另 一实施方式中, 所述分享资源数据库 202可以与统计服务器通信, 从统计服 务器获取点击所述链接入口信息的用户 (此处为下载客户端 302的 P2SP帐 号)的下载行为记录, 所述中转服务器 203在生成所述中转页面之前, 进一 步从下载客户端 302获取其 P2SP帐号, 根据该帐号从分享资源数据库 202 中查询该帐号的下载行为记录, 并根据该下载行为记录生成针对该用户的推 荐内容, 随后生成中转页面发送给下载客户端 302, 该中转页面中包括网络 资源的源下载链接地址、 相关描述信息、 以及所述推荐内容。 所述根据用户 的下载行为记录生成针对该用户的推荐内容例如可以具体为: 分析下载行为 记录中用户下载次数最多的资源类别, 如某个用户可能对电影类的资源下载 的最多,则可以根据该资源类别从某个资源数据库中(例如合作的资源网站 ) 获取同类别的电影类网络资源下载信息, 将这些电影类的网络资源下载信息 作为所述推荐内容。 通过这种推荐内容的机制, 可以提高中转页面内容的转 化效率。
本发明所在微博中发布的并不是可以直接访问到网络资源的源下载链 接地址, 而是一种下载链接入口地址, 通过点击该下载链接入口地址会触发 下载控制鉴权, 只有符合下载控制条件才会允许下载, 因此, 本发明可以根 据控制需求, 有效地控制网络资源下载信息的传播风险, 尤其可以有效地控 制非法信息的分享和传播风险。
另外, 微博的初衷就是微型博客, 对所发布内容的长度有严格的限制, 例如目前通常每条内容的长度限制在 140个字, 相当于两条短信的容量, 这 个长度限制是移动通信标准决定的, 即根据国际标准, 每条短信最多发送 1120位, 合 140字节的内容, 因此微博系统设定了这个上限。 然而, 目前许 多网络资源的源下载链接的字数都超过 140字节, 而且通常的下载信息还要 包括一些对网络资源的描述信息, 如果通过 專进行分享, 由于 專对发布 内容的长度限制, 造成许多超过微博长度限制的源下载链接内容无法发布分 享成功, 利用微博发布网络资源下载信息的成功率比较低, 而且由于微博字 数限制导致了其对网络资源的表现力不足。 而在本发明中, 所述下载链接入 口地址要符合微博的发布标准, 即下载链接入口地址的长度小于微博所允许 的最大信息长度, 这样就可以大大提高利用微博发布网络资源下载信息的成 功率, 并可以在中转页面提供具体分享的内容及资源描述和源下载链接地 址, 可以解决微博上 140字表现力不足的问题。
以上所述, 仅是本发明的实施例而已, 并非对本发明作任何形式上的限 制, 虽然本发明已以实施例揭露如上, 然而并非用以限定本发明, 任何熟悉 本专业的技术人员, 在不脱离本发明技术方案范围内, 当可利用上述揭示的 技术内容作出些许更动或修饰为等同变化的等效实施例, 但凡是未脱离本发 改、 等同变化与修饰, 均仍属于本发明技术方案的范围内。
工业实用性
本发明所在微博中发布的并不是可以直接访问到网络资源的源下载链 接地址, 而是一种下载链接入口地址, 通过点击该下载链接入口地址会触发 下载控制鉴权, 只有符合下载控制条件才会允许下载, 因此, 本发明可以根 据控制需求, 有效地控制网络资源下载信息的传播风险, 尤其可以有效地控 制非法信息的分享和传播风险。
