背景技术
服务提供商自建媒资中心管理所有的媒资内容并进行分类运营，每与一家广电运营商签订服务提供商身份合作后，需要将中心结点的内容同步到运营商的点播系统进行呈现与播放，此处，将每个签订合作的广电运营商作为媒资中心的一个项目。
为保证推送成本，媒资中心推送的是各个项目所需的媒资元数据，而非具体媒资，此处，将媒资元数据作为媒资属性进行推送。每个项目处配置有独立的数据库，在某个项目需要媒资属性时，由该项目向媒资中心发送媒资属性获取请求，再由媒资中心将该项目所需的媒资属性推送至该项目，并存储在该项目的数据库中。
但是，由于现有的媒资属性推送方法是采用“谁请求向谁推送”的方式，媒资中心的媒资属性的推送较为被动，通过项目的请求再进行推送较为浪费时间，无法保证媒资中心是否能够及时地向每个项目推送媒资属性。

具体实施方式
本申请实施例提供的一种媒资属性推送方法，应用于媒资属性推送服务器，如媒资中心，媒资中心内存储有媒资元数据，媒资中心为多个项目主动推送媒资元数据，可以实现媒资中心与多个项目之间进行媒资元数据的同步，达到促进媒资元数据共享，提高资源利用率的目的。
媒资元数据可为教育领域的元数据，此时，教育媒资元数据统一存储在媒资中心。媒资中心存储有教育媒资的名称、年级、一级科目、二级科目、教材版本、所属教材章节等属性。教育媒资在多个项目中共享，每个项目均配置有独立的数据库，需要从媒资中心同步媒资元数据，不同的项目有不同的媒资同步范围，根据每个项目的需求，由媒资中心将对应的教育媒资元数据主动推送至每个项目。
图1为本申请实施例提供的媒资属性推送服务器与项目的交互结构框图。参见图1所示的媒资中心200和项目群100的交互结构框图，其中，媒资中心200包括媒资同步接口201、开源消息队列系统202、媒资推送器203和媒资数据库204；项目群100包括项目1、项目2、项目3……项目n。媒资同步接口201与每个项目进行通信，每个项目通过媒资同步接口201进行注册，并由媒资同步接口201将注册信息存储在媒资数据库204。开源消息队列系统202分别与媒资同步接口201和媒资推送器203连接，媒资推送器203通过开源消息队列系统202监听媒资同步接口201处是否产生新注册方消息，以便向当前注册项目推送媒资属性。在某个项目通过媒资同步接口201进行注册时，媒资推送器203通过开源消息队列系统202监听到新注册方消息，同时读取已通过注册过程存储在媒资数据库204中该项目的注册信息，基于注册消息，向该项目主动推送对应的媒资属性。
媒资数据库204存储有教育媒资元数据，包括存储媒资ID和存储媒资属性。同时，每个项目的注册消息也存储在媒资数据库。每个项目在媒资中心注册时，会存储项目ID、注册媒资范围、注册媒资属性和回调地址等信息。
为了使得媒资中心能够将每个项目所需的媒资属性主动推送至相应项目，并在媒资中心的媒资属性发生更新时，能够及时地向每个项目推送相应的媒资属性，本申请实施例提供的媒资属性推送方法，通过计算每个项目的同步媒资范围，可以保证在存在新注册方以及媒资属性发生变更时，实现实时同步。
图2为本申请实施例提供的媒资属性推送方法的数据流图；图3为本申请实施例提供的媒资属性推送方法的流程图。参见图2和图3，本申请实施例提供的一种媒资属性推送方法，应用于媒资推送器203，媒资推送器203包括存储器2031和处理器2032，处理器2032执行的该方法包括以下步骤：
S101、获取媒资数据库中存储的指定项目的注册媒资范围和回调地址，注册媒资范围是所述指定项目在注册时确定的媒资类型，回调地址是所述指定项目接收媒资属性推送的路径。
在为每个项目推送媒资属性时，由媒资推送器通过开源消息队列系统监听到该项目已通过媒资同步接口完成注册之后，向媒资数据库读取该项目的注册信息，以为该项目推送媒资属性。
指定项目的注册信息包括注册媒资范围和回调地址，注册媒资范围用于圈定指定项目的媒资类型，以确定指定项目所需的是哪一类型的媒资，例如，以年级属性圈定所有小学类型的媒资，或者，以年级属性圈定所有中学类型的媒资。
回调地址用于提供一种路径，在媒资推送器确定出可向指定项目推送媒资属性后，将相应的媒资属性沿回调地址推送至指定项目，完成媒资属性的同步。
S102、发送携带指定项目的注册媒资范围的查询指令至媒资数据库，查询指令用于使媒资数据库根据指定项目的注册媒资范围查询对应的存储媒资ID，形成存储媒资ID集合，媒资数据库包括存储媒资ID和对应的存储媒资属性。
媒资推送器在确定出指定项目所需的媒资类型之后，在媒资数据库中查询与指定项目的媒资类型对应的存储媒资ID，存储媒资ID用于表征媒资数据库中存储的每个媒资类型的名称。
每个指定项目的注册媒资范围与媒资数据库中存储的媒资类型存在对应关系，根据指定项目的注册媒资范围，即可在媒资数据库中确定出对应的存储媒资ID，将与指定项目的注册媒资范围对应的至少一个存储媒资ID查找出来，并生成存储媒资ID集合。
媒资推送器在获取到指定项目的注册信息之后，生成查询指令，并发送至媒资数 据库，以查询媒资数据库中与指定项目的注册媒资范围对应的存储媒资ID集合。
S103、接收媒资数据库返回的存储媒资ID集合。
媒资数据库根据查询指令将与指定项目的注册媒资范围对应的存储媒资ID形成存储媒资ID集合，并发送至媒资推送器。
S104、根据存储媒资ID集合，发送媒资属性获取指令至媒资数据库，媒资属性获取指令用于获取媒资数据库中与存储媒资ID集合中的每个存储媒资ID对应的存储媒资属性。
存储媒资ID集合可以确定出向指定项目推送的媒资属性，因此，媒资推送器在查询到存储媒资ID集合之后，生成媒资属性获取指令，并发送至媒资数据库。
存储媒资ID集合中包括至少一个存储媒资ID，每个存储媒资ID对应一个存储媒资属性，因此，可根据存储媒资ID集合中每个存储媒资ID，确定出至少一个存储媒资属性。
S105、接收媒资数据库返回的与每个存储媒资ID相对应的存储媒资属性。
媒资数据库根据媒资属性获取指令将与每个存储媒资ID对应的存储媒资属性挑选出来，并发送至媒资推送器。
S106、基于回调地址，将每个存储媒资属性推送至指定项目。
每个指定项目在注册时，存储在媒资数据库的注册信息中包括回调地址，在根据本实施例提供的方法确定出可向指定项目推送的媒资属性之后，媒资推送器根据回调地址，将查找出的存储媒资属性推送至该指定项目。
可见，本申请实施例提供的媒资属性推送方法，可以由媒资推送器实时监听每个项目的注册情况，在监听到某个项目完成注册后，及时根据该项目的注册信息，在媒资数据库中查找出对应的媒资属性，并将查找出的媒资属性依据每个项目对应的回调地址主动推送至相应项目，实现媒资中心的媒资属性向每个项目的实时同步，实现教育媒资元数据的共享，提高资源利用率。
在媒资中心中存储的媒资属性发生变化或更新时，为了使得更新后的媒资属性能够实时同步给相应的项目，本申请实施例提供的方法，在完成一次项目的媒资属性的推送之后，计算每个项目的签名，并存储在媒资数据库，以作为后序判断需要向该项目推送更新的媒资属性的依据。
图4为本申请实施例提供的媒资属性推送方法的另一方法流程图。
具体地，参见图4，本申请实施例提供的方法，基于前述实施例提供的方法基础上，还包括：
S201、获取媒资数据库中存储的指定项目的注册媒资属性和项目ID，注册媒资属 性是指定项目在注册时确定的与媒资类型对应的媒资信息。
为计算每个项目的签名，本实施例中，采用基于每个项目的注册媒资属性并利用MD5算法计算签名的方式。
指定项目在媒体中心注册时，媒资数据库中存储的注册信息还包括注册媒资属性和项目ID。由媒资推送器向媒资数据库中获取指定项目的注册媒资属性和项目ID。
注册媒资属性用于确定指定项目具体所需的媒资信息，即指定项目所关注的媒资信息，此时，媒资推送器可向指定项目推送的媒资信息。注册媒资属性包括：名称、年级、一级科目、二级科目、教材版本、所属教材章节、讲师、视频列表详情、视频对应的知识点信息等媒资元数据。注册媒资范围用于圈定媒资类型，而注册媒资属性则用于明确在该媒资类型下的所有媒资信息。
例如，以年级属性圈定所有小学类型的媒资，则对应的注册媒资属性为小学类型的各元数据的名称、年级、一级科目、二级科目、教材版本、所属教材章节、讲师、视频列表详情、视频对应的知识点信息等。
S202、根据指定项目的注册媒资属性，计算指定项目的初始签名。
S203、将指定项目的初始签名和项目ID发送至媒资数据库，进行存储。
媒资推送器依据指定项目的注册媒资属性，利用MD5算法，通过计算得到的MD5值作为指定项目的初始签名。将每个指定项目的初始签名与对应的项目ID建立关联关系，并由媒资推送器将该关联关系发送至媒资数据库，以在媒资数据库进行存储。
将每个项目的初始签名和项目ID存储在媒资数据库，便于后续在媒资数据库中的存储媒资属性发生变化时，通过调用与发生变化的存储媒资属性对应的项目ID和初始签名，以根据初始签名来判断该项目是否需要更新自身的媒资属性，进而实现媒资属性的实时同步。
图5为本申请实施例提供的计算签名的方法流程图。参见图5，本申请实施例提供的方法，在计算每个指定项目的初始签名时，采用MD5算法，具体地，步骤S202中，按照下述步骤根据指定项目的注册媒资属性，计算指定项目的初始签名：
S301、分别计算所述一级媒资属性的MD5值和每个二级媒资属性的MD5值。
本实施例采用二级MD5算法，此时，注册媒资属性包括一级媒资属性和至少一个二级媒资属性。一级媒资属性是指媒资本身的属性，包括：名称、年级、一级科目、二级科目、教材版本等。二级媒资属性是指媒资对应的视频列表，由于每个媒资属性对应多个视频列表，因此二次媒资属性可为多个。
利用MD5算法，对一级媒资属性做字符串合并处理，并计算MD5值；同时，对每个二级媒资属性中的每个视频列表，基于每个视频属性(播放地址、对应的知识点、 教材章节等)做字符串合并处理，并计算MD5值。以此，得到一个一级媒资属性的MD5值和多个二级媒资属性的MD5值。
S302、将一级媒资属性的MD5值和每个二级媒资属性的MD5值进行合并计算，得到目标MD5值。
为确定每个项目的唯一的MD5值，本实施例中，将媒资和视频列表的MD5值再做二次合并，即将一级媒资属性的MD5值和每个二级媒资属性的MD5值进行再次合并，通过MD5算法再次进行计算，得到最终的MD5值，即目标MD5值。
S303、将目标MD5值确定为指定项目的初始签名。
每个指定项目对应一个目标MD5值，将该目标MD5值作为该指定项目的初始签名。
由于媒资数据库中的媒资元数据是会更新和变化的，而在媒资数据库中的媒资属性发生变化或更新后，需及时向每个项目同步该媒资属性，以提高资源利用率。为此，本申请实施例还提供一种媒资推送方法，应用在媒资数据库发生媒资属性变化的情况。
图6为本申请实施例提供的媒资属性推送方法的又一流程图。具体地，参见图6，本申请实施例提供的媒资推送方法，基于前述实施例提供的方法，还包括：
S401、接收开源消息队列系统发送的变更通知，变更通知是指媒资数据库在存储媒资属性发生变化时生成并发送至开源消息队列系统的通知。
媒资数据库处配置有实时监控系统，该监控系统用于实时监控媒资数据库中的媒资属性是否发生变化。在监控系统监控到媒资数据库中的媒资属性发生变化时，生成变更通知，由媒资数据库发送至开源消息队列系统，再由开源消息队列系统将该变更通知发送至媒资推送器。
媒资推送器接收到变更通知后，可执行后续的步骤，即根据媒资数据库中发生变化的媒资属性确定可以进行媒资属性更新的项目，再将发生变化的媒资属性推送至该项目。
S402、响应于变更通知，获取与媒资数据库中的新媒资属性对应的待更新项目ID，新媒资属性是指媒资数据库中发生变化的存储媒资属性，待更新项目ID是指需要进行媒资属性更新的项目ID。
根据每个项目的注册媒资属性，可确定媒资数据库中的存储媒资属性对应至少一个项目，即每个项目与媒资数据库中的存储媒资属性存在对应关系。因此，在媒资数据库中存在变化的存储媒资属性，即可根据该变化的存储媒资属性确定出哪些项目可能需要进行媒资属性更新。此时，将可能需要进行媒资属性更新的项目称为待更新项目，将媒资数据库中发生变化的存储媒资属性称为新媒资属性。
为此，媒资推送器根据变更通知，在媒资数据库中获取与新媒资属性对应的待更新项目ID，待更新项目ID对应的待更新项目与新媒资属性具有相同的媒资属性。
S403、将新媒资属性推送至待更新项目ID对应的待更新项目。
如果媒资推送器查找到与新媒资属性对应的待更新项目ID，则将该新媒资属性推送给该待更新项目。
本实施例，在媒资推送器将新媒资属性推送给待更新项目时，采用的方法是签名对比的方式，即还需对待更新项目的签名进行再次计算，在与初始签名对比不一致时，再将新媒资属性推送给待更新项目。
图7为本申请实施例提供的推送新媒资属性的方法流程图。具体地，参见图7，本实施例中，将新媒资属性推送至所述待更新项目ID对应的待更新项目，即步骤S403包括：
S501、基于待更新项目ID，获取媒资数据库存储的待更新项目的注册媒资属性、初始签名和回调地址。
媒资推送器根据待更新项目ID，在媒资数据库中调取该待更新项目的注册信息和初始签名，注册信息包括注册媒资属性和回调地址。
初始签名为媒资推送器首次为该项目推送媒资属性后计算的签名。
S502、根据待更新项目的注册媒资属性，计算待更新项目的更新签名。
如果某个项目需要进行媒资属性的更新，则该项目的签名会发生变化。因此，再次根据待更新项目的注册媒资属性计算更新签名。更新签名可看做是该项目的当前签名。
本实施例中，在计算待更新项目的更新签名的方法可参照步骤S301至S303的相关内容，此处不再赘述。二级MD5算法可以保证媒资属性变更的敏感性，减少存储成本。
S503、对比更新签名和初始签名。
S504、如果更新签名和初始签名不一致，则基于待更新项目ID和回调地址，将对应的新媒资属性推送至待更新项目。
将待更新项目的初始签名和更新签名进行对比，如果二者一致，说明待更新项目不需要进行媒资属性的更新，而如果二者不一致，则说明待更新项目需要进行媒资属性的更新，此时，由媒资推送器基于待更新项目ID和回调地址，将与待更新项目对应的新媒资属性推送给对应的待更新项目，实现媒资中心处产生媒资属性更新时的实时同步至项目，提高资源利用率。
例如，广东电信的注册媒资属性是一年级、人教版，而江苏电信的注册媒资属性 为二年级、语文，在初次为上述两个项目推送媒资属性时，媒资推送器可将媒资数据库中存储的一年级和人教版的媒资信息推送给广东电信，将二年级和语文对应的媒资信息推送给江苏电信。
而如果媒资数据库中产生媒资属性的变化，例如，新媒资属性为三年级、人教版，此时，根据人教版的媒资属性确定可以进行媒资属性更新的项目是广东电信。再计算广东电信的当前签名，若当前签名与广东电信的初始签名不一致，则将三年级、人教版对应的媒资属性推送给广东电信，而不推送给江苏电信。
可见，本申请实施例提供的方法，通过媒资数据库中媒资属性的变更，向对应的项目实时通知，再通过计算每个项目的当前签名，与相应项目的初始签名进行对比，在对比不一致时，将变更的媒资属性，基于相应项目的ID推送给对应的项目，实现媒资中心的媒资属性变更时向各个项目的实时同步，确保每个项目能够接收到最新的媒资属性。同时，还可避免无效的通知推送，减少各项目间交互的网络成本以及运行成本。
从上述实施例可以看出，本申请实施例提供的一种媒资属性推送方法，包括：由媒资推送器获取媒资数据库中存储的指定项目的注册信息，该注册信息包括媒资范围和回调地址。发送携带指定项目的注册媒资范围的查询指令至媒资数据库，接收媒资数据库根据查询指令返回的存储媒资ID集合。发送媒资属性获取指令至媒资数据库，接收媒资数据库根据媒资属性获取指令返回的每个存储媒资ID对应的存储媒资属性；基于回调地址，由媒资推送器将每个存储媒资属性推送至指定项目。可见，本申请提供的方法，由媒资推送器实时监听每个项目的注册信息，在监听到指定项目注册完成时，在媒资数据库中查找与指定项目的注册信息相匹配的存储媒资属性，并将该存储媒资属性主动推送至该指定项目，完成媒资属性的实时同步。该方法可以实现媒资中心与多个项目之间进行媒资元数据的同步，达到促进媒资元数据共享，提高资源利用率的目的。
