请参照图1，图1为本发明实施例一提供的提供文件读取列表的方法的流程图。Please refer to FIG. 1 . FIG. 1 is a flowchart of a method for providing a file read list provided by Embodiment 1 of the present invention.
本优选实施例的提供文件读取列表的方法，包括：The method for providing a file reading list in this preferred embodiment includes:
步骤S101，建立文件读取列表；Step S101, establishing a file read list;
例如，该文件读取列表包括多个最近被读取的文件信息；数字媒体服务器在第一次启动时便建立读取列表数据库，该数据库用于记录最近被读取文件的文件信息，以通过该文件信息建立该文件读取列表；该文件可为音频、视频、图片等。For example, the file read list includes a plurality of recently read file information; the digital media server will establish a read list database when it is first started, and this database is used to record the file information of the recently read file, so as to pass The file information establishes the file read list; the file can be audio, video, picture, etc.
例如，DMS收到文件数据读取请求后，将被读取的文件信息保存到本地数据库，建立文件读取列表；该文件信息包括标示信息；For example, after DMS receives the file data read request, it saves the read file information to the local database, and builds a file read list; the file information includes label information;
优选地，该建立文件读取列表的步骤包括：Preferably, the step of establishing a file read list includes:
A、在接收到文件读取请求之后，获取被读取文件的文件信息并存储；A. After receiving the file reading request, obtain and store the file information of the read file;
例如，该文件信息包括标示信息、录入时间、文件类型等等，DMS第一次启动后建立文件读取列表数据库，用于记录最近被读取文件的ObjectId信息(即标示信息)；当DMS的HTTP文件服务器收到任何终端的读取请求后，将被请求的文件ObjectId、文件类型及当前写入的时间等信息录入该数据库中；For example, the file information includes marking information, entry time, file type, etc., and the DMS establishes a file reading list database after the first startup, which is used to record the ObjectId information (that is, marking information) of the recently read file; when the DMS After the HTTP file server receives a read request from any terminal, it will enter the requested file ObjectId, file type, and current writing time into the database;
B、根据该文件信息建立该文件读取列表。B. Establish the file read list according to the file information.
为了使得文件读取列表的信息更加准确、且没有重复的文件信息，即，该根据该文件信息建立该文件读取列表的步骤包括：In order to make the information of the file reading list more accurate and without repeated file information, that is, the step of establishing the file reading list according to the file information includes:
1)、判断该标示信息是否已经存储在数据库中；该文件信息包括标示信息和录入时间；1) Determine whether the marked information has been stored in the database; the file information includes marked information and entry time;
2)如果是，则更新该文件的录入时间。2) If yes, update the entry time of the file.
例如，当DMS录入数据库时，需判断当前文件的ObjectId是否已经被写入，若已经有记录，则仅需更新当前的录入时间；若没有记录，则将其存入数据库。For example, when the DMS is entering the database, it needs to determine whether the ObjectId of the current file has been written. If there is a record, it only needs to update the current entry time; if there is no record, it will be stored in the database.
当然DMS可以根据自身设备的资源大小，规定记录的文件数目的容量，在容量达到记录最大值后，如果有添加新的文件数据时，则可以将时间最久的记录删除。Of course, DMS can specify the capacity of the number of recorded files according to the resource size of its own equipment. After the capacity reaches the maximum value of records, if there is new file data added, the record with the longest time can be deleted.
步骤S102，接收到数字媒体控制器发送的列表查看请求时，根据该列表查看请求在该多个最近被读取的文件信息中选取目标文件信息；Step S102, when receiving a list view request sent by the digital media controller, select target file information from the plurality of recently read file information according to the list view request;
该请求过程例如为：DMC加入网络，并选择访问某个DMS服务器；DMC通过列表方式浏览某DMS资源；DMS不提供最近播放列表文件夹，需要通过DMC的界面交互直接访问最近播放列表；DMC向DMS发送X_GetRencentPlaylist动作，根据该查看请求的具体要求选取目标文件信息；The request process is, for example: DMC joins the network and chooses to access a certain DMS server; DMC browses a certain DMS resource through a list; DMS does not provide a recent playlist folder, and needs to directly access the recent playlist through DMC interface interaction; The DMS sends the X_GetRencentPlaylist action to select the target file information according to the specific requirements of the viewing request;
当收到DMC的自定义请求动作，例如X_GetRencentPlaylist后，DMS需根据动作参数，筛选当前数据库中的文件，并根据ObjectId寻找到文件详细信息(Id3信息等)，该自定义请求动作X_GetRencentPlaylist，属于对UPnP协议的扩展，该动作定义在ContentDirectoryService服务之下，用来向DMS请求最近播放列表。其中动作参数包括请求列表的起始位置和请求数量、请求文件的类型(如仅请求音频，视频或图片)、列表显示顺序(正序或倒序)等。After receiving the custom request action of DMC, such as X_GetRencentPlaylist, DMS needs to filter the files in the current database according to the action parameters, and find the detailed information of the file (Id3 information, etc.) according to the ObjectId. The custom request action X_GetRencentPlaylist belongs to the object An extension of the UPnP protocol, this action is defined under the ContentDirectoryService service, and is used to request the latest playlist from the DMS. The action parameters include the starting position and the number of requests in the request list, the type of the requested file (such as requesting only audio, video or picture), the list display order (forward or reverse), etc.
优选地，为了提高筛选的效率，该列表查看请求可携带查询参数；该根据该列表查看请求在该多个最近被读取的文件信息中选取目标文件信息的步骤包括：Preferably, in order to improve the efficiency of screening, the list viewing request can carry query parameters; the step of selecting target file information from the plurality of recently read file information according to the list viewing request includes:
在该多个最近被读取的文件中选取与该查询参数匹配的文件信息，以作为该目标文件信息。The file information matching the query parameter is selected from the plurality of recently read files as the target file information.
例如，以歌曲为例，DMC在浏览DMS文件目录时，可以直接通过自定义动作，向DMS请求查看最近播放歌曲列表的信息；DMS获取到自定义动作后，将数据库中记录的最近播放歌曲，按照DMC请求的查询参数，筛选与该查询参数匹配的文件信息；For example, taking songs as an example, when DMC browses the DMS file directory, it can directly request DMS to view the information of the list of recently played songs through a custom action; According to the query parameters requested by the DMC, filter the file information matching the query parameters;
例如该查询参数为DMC请求获取文件读取列表的起始位置和请求数量、请求文件的类型(如音频、视频或图片)、列表显示顺序(正序或倒序)等。For example, the query parameters are the starting position and the requested quantity of the file read list requested by the DMC, the type of the requested file (such as audio, video or picture), the display order of the list (forward or reverse), etc.
步骤S103，根据该目标文件信息生成目标文件读取列表；Step S103, generating a target file read list according to the target file information;
DMS将匹配到的文件信息生成目标文件读取列表；优选地，还可以生成预设格式的目标文件读取列表。例如将找到的文件信息按照UPnP协议生成xml格式的Metadata列表信息。The DMS generates a target file read list from the matched file information; preferably, a target file read list in a preset format can also be generated. For example, the found file information is generated into Metadata list information in xml format according to the UPnP protocol.
步骤S104，将该目标文件读取列表反馈给该数字媒体控制器。Step S104, feeding back the target file read list to the digital media controller.
例如，DMS将该目标文件读取列表发送给DMC。For example, the DMS sends the target file read list to the DMC.
