Description

数据下载方法、装置及终端

技术领域
本公开涉及数据下载技术领域，尤其涉及一种数据下载方法、装置及终端。
背景技术
用户为了保证在观看视频或听音乐过程中的流畅程度，如果涉及到数据文件较大的视频或音乐的话，一般都会选择将数据文件事先下载到用户终端设备上，然后再观看下载后的本地文件，从而提升用户的视觉或听觉体验。
相关技术中，在进行数据下载的过程中，用户一般会下载一个数据文件或者同时下载多个数据文件，数据文件在进行下载过程中根据数据文件的下载资源或网速差异等多少造成数据文件的下载速度发生有所改变，可能会造成用户同时下载的多个数据文件分别在不同时间内下载完成。在同时下载的数据文件中，如果有用户需要实现最先观看或能够下载完成的数据文件的情况下，很可能会因为其他数据文件下载资源较多，造成其他数据文件下载速度较快占用终端的存储空间，一旦终端剩余的存储空间不足，那么该数据文件就会中断下载。
目前，很有可能出现数据文件中断下载时间较长或其他原因造成该数据文件的数据包丢失，虽然可以通过暂停其他数据文件的下载或者删除其他无用数据等为该数据文件腾出存储空间，使得该数据文件能够继续下载，但是，在这种情况下还是有可能出现上述情况，即使最终数据文件下载完成也无法观看。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种数据下载方法的流程图，该方法应用在终端上，例如移动终端，该方法包括如下步骤：
在步骤S101中，检测是否接收到需要完成下载的第一数据文件的第一数据下载指令。否则，结束流程，可按照相关技术下载数据文件。
在本公开实施例中，终端在下载数据的时候，都会同时下载一个或多个数据文件，例如：当用户点击下载多个数据文件时，但是，为了保证能够在下载完成后能够完成查看自己想要查看的数据文件，则需要将该数据文件完成下载，该数据文件即为本实施例提出的需要完成下载的第一数据文件。该第一数据下载指令即为需要完成第一数据文件下载、并存储于终端存储空间的下载指令。通过检测第一数据下载指令的身份识别标识来确认是否接收到该第一数据下载指令，该身份识别标识可以为字符串，身份识别标识可以表示服务器能够响应下载的数据文件的身份识别标识。
另外，该第一数据下载指令也可以是用户没有指定的数据文件对应的数据下载指令，而是按照用户最初点击下载时，每个数据文件的开始下载的时间顺序来定，从而使得开始下载时间最早的数据文件即为第一数据文件。
当接收到需要完成下载的第一数据文件的第一数据下载指令时，在步骤S102中，为所述第一数据文件预留第一存储空间。
该第一存储空间即为存储第一数据文件的终端内的存储空间，为了保证第一数据文件下载完成的数据信息能够完全存储于该第一存储空间，该第一存储空间 的大小至少与第一数据文件的数据大小相同，或者略大于第一数据文件的数据大小。从而生成需要在该终端内剩余的存储空间中预留该第一存储空间后，从而便于将下载的第一数据文件对应的数据信息均存储于该第一存储空间。
另外，在本公开实施例中，该第一存储空间的大小可以小于终端内存储器的剩余存储空间；当然，该第一存储空间的大小也可以大于终端内存储器的剩余存储空间；如果第一存储空间大于终端内存储器的剩余存储空间，则需要用户清除一些终端内不必要的信息，保证能够预留出该第一存储空间，便于存储第一数据文件对应的数据信息。
在步骤S103中，将所述第一数据文件下载至所述第一存储空间。
该第一存储空间即为用于存储该第一数据文件的数据信息，因此，当下载该第一数据文件时，可以在下载的过程中即可将该第一数据文件的数据信息存储于该第一存储空间内；也可以在第一数据文件的数据信息全部下载完成后，存储于该第一存储空间内。
应用该方法，能够在下载该第一数据文件时，事先在终端的剩余存储空间中预留该第一存储空间，从而将终端内部分剩余存储空间占用，使得该第一数据文件对应的数据信息下载完成后能够存储在该第一存储空间内，保证该第一数据文件能够完全下载，保证用户观看效果，有效提高数据下载的可靠性和用户体验效果。
图2是根据一示例性实施例示出的另一种数据下载方法的流程图，该数据下载方法包括以下步骤：
在步骤S1011中，接收用户发送的多个数据文件的数据下载指令。
本公开实施例中，用户可以同时接收多个数据文件的多个数据下载指令，也可以接收一个数据文件的数据下载指令；当接收一个数据文件的数据下载指令时，则可以直接按照步骤S102执行即可。
当接收到多个数据文件的数据下载指令时，在步骤S1012中，获取所述多个数据文件分别对应的数据下载指令的优先级。
该数据下载指令的优先级即为该数据下载指令对应的数据文件优先完成下载并存储于终端的顺序，在本公开实施例中，该数据下载指令可以携带有优先级识别标识，该优先级识别标识可以为字符串，通过该优先级识别标识字符串判断 该数据下载指令的优先级，进而确定与数据下载指令对应的数据文件进行下载时的优先级。例如，该优先级识别标识为数据文件开始下载的时间标识时，如果两个数据下载指令的优先级识别标识分别为第一时间标识和第二时间标识，且第一时间标识表示的时间早于第二时间标识表示的时间，则表示该第一时间标识对应的数据下载指令的优先级高于第二时间标识对应的数据下载指令。
当获取到数据下载指令的优先级时，在步骤S1013中，确定优先级最高的数据下载指令对应的数据文件为所述第一数据文件，并确定接收到所述第一数据下载指令。
在本公开实施例中，步骤S1012中获取到多个数据文件分别对应的数据下载指令的优先级，从而便可知道数据文件下载的优先级，根据优先级的大小即可确定优先级最高的数据下载指令对应的数据文件即为本公开实施例中用户需要完成下载的第一数据文件，从而确定接收该第一数据文件对应的数据下载指令，且该数据下载指令即为步骤S101中所述的第一数据下载指令。
另外，在本公开实施例中提出的第一数据文件以及第一数据下载指令并非表示其优先级的高低，主要是为了区别多个数据文件同时存在时，将用户需要优先下载完成的数据文件与其他数据文件进行区分。
应用该方法，能够从多个数据文件对应的数据下载指令中确定数据文件下载的优先级，从而确定需要完成下载的数据文件，并对应预留第一存储空间存储该数据文件，从而有效避免多个数据文件同时下载、无法确定最高优先级数据下载并存储的情况，有效提高数据下载的可靠性。
上述实施例中提出的数据下载方法中，可以实现存在多个数据文件同时下载、且用户没有另外指定需要下载哪一个数据文件的情况，该优先级即可按照用户点击下载数据文件时的开始时间。但是，在实际操作过程中，用户很有可能根据需要随时改变数据文件下载的优先级，因此，本公开还提供了另外一种数据下载方法的实施例方式，具体可参看图3所示的数据下载方法的流程示意图。如图3所示，该方法可以包括如下步骤：
步骤S1014：接收来自用户发送的优先级变更指令。
在本公开实施例中，优先级变更指令为用户发送的用户变更数据文件下载优先级的指令，通过变更数据文件下载的优先级，确定该变更后的数据文件为用户 需要完成下载并存储的数据文件。
当接收到优先级变更指令，在步骤S1015中，提取所述优先级变更指令携带的身份识别标识。
该优先级变更指令中可以包括身份识别标识，该身份识别标识表示数据下载指令的标识，通过身份识别标识确认该优先级变更指令用于变更哪一个数据文件对应的数据下载指令。在本公开实施例中，该身份识别标识可以为字符串，例如，身份识别标识为四位二进制字符串，如0010。
当提取到优先级变更指令的身份识别标识时，在步骤S1016中，查询与所述身份识别标识相匹配的数据下载指令。
其中，该数据下载指令中可以预先存储有自身的识别标识，且该识别标识与身份识别标识相同，也可以为字符串，接收到该身份识别标识后，获取该识别标识的字符串，通过查询所有数据文件下载的数据下载指令的识别标识，确定与该身份识别标识相同的数据下载指令即为需要变更优先级的数据文件。例如：目前有三个数据文件的数据下载指令A、B和C分别对应的识别标识的字符串为0010、0011和0100，如果接收到的该优先级变更指令的身份识别标识为0011，则对应查询的需要更改优先级的数据文件为数据下载指令B对应的数据文件。
当查询到与所述身份识别标识相匹配的数据下载指令时，在步骤S1017中，将与所述身份识别标识相匹配的数据下载指令变更为优先级最高的第一数据下载指令。
本公开实施例中，在查询到需要变更下载优先级的数据下载指令后，即可更改该数据下载指令的优先级，将该数据下载指令对应的数据文件的下载优先级变为最高优先级，从而使该数据文件完成数据下载之后存储于生成的第一存储空间内。
应用该方法，能够在多个数据文件同时下载时，用户用于指示某个数据文件的存储优先级，从而为该数据文件对应生成一匹配的第一存储空间，便于该数据文件能够在下载完成后存储于该第一存储空间，从而避免数据文件在下载过程中因为其他文件占用终端内的存储空间导致该数据文件无法完成下载、造成数据丢失的情况，从而有效提高数据下载的可靠性。
基于图3之上，在本公开实施例中，如图4所示，该步骤S1012可以包括如 下步骤：
当接收到多个数据文件的数据下载指令时，在步骤S10121中，提取所述数据下载指令的优先级识别标识。
其中，在本实施例中，该数据下载指令可以预先存储有优先级识别标识，该优先级识别标识可以为字符串。该优先级识别标识可以包括时间标识位和优先级标识位，且优先级标识位的优先级高于时间标识位的优先级，当接收到多个数据文件的数据下载指令时，需要分别提取每一个数据文件对应的数据下载指令的优先级识别标识。
当提取到所述优先级识别标识，在步骤S10122中，根据所述优先级识别标识，确定多个所述数据下载指令的优先级。
在本公开实施例中，通常情况下，数据文件下载时的优先级可以仅参考优先级识别标识的时间标识位，如开始下载时间越早优先级越高，且此时优先级识别标识的优先级标识位的字符均相同；如果需要变更数据下载指令的优先级，则可通过改变优先级标识位的字符区别其他数据下载指令的优先级识别标识获得最高优先权，例如：三个数据下载指令A、B、C开始下载时间依次增大(即数据下载指令A的时间早于数据下载指令B和C)，且数据下载指令A、B、C分别对应的优先级标识位的字符相同均为0，此时则表示数据下载指令A的优先级最高，当需要变更数据下载指令C的优先级时，则将该数据下载指令B对应的优先级标识位的字符变更为1，则此时数据下载指令B的优先级最高，数据下载指令A和C可以仍按照时间标识位的优先级排列。
上述实施方式仅为解释该实施例列举的优选实施例方式，在具体实施过程中并不限于上述实施方式，其他相同或相近的实施方式都归为本公开实施例，在此不再详述。
应用该方法，能够通过数据下载指令的优先级识别标识中的时间标识位和优先级标识位自身的优先级级别区分数据下载指令的优先级，并根据时间标识位或优先级标识位内的字符串确定数据下载指令的优先级，最终确定所有数据下载指令的优先级次序，进一步可以确定出最高优先级的数据下载指令。
如图5所示，为本公开实施例提供了另外一种数据下载方法的流程示意图，该方法包括如下步骤：
步骤S1021：获取所述第一数据文件存储空间的大小。
当确定接收到用户需要完成下载的第一数据文件的第一数据下载指令时，需要预留与该第一数据文件相对应的第一存储空间，用于存储该第一数据文件。由于生成的该第一存储空间的大小至少应该与第一数据文件的文件大小相同，因此，需要通过获取该第一数据文件的存储空间的大小。
另外，在本公开实施例中，数据文件的数据下载指令可以包括对应的数据文件的文件大小，或者，数据下载指令中携带有数据文件的文件大小标识，存储该数据文件的文件大小(一般情况下，数据文件的文件大小即为数据文件存储的存储空间的大小)，从而接收到该第一数据下载指令后，可以直接获取该数据下载指令对应的数据文件的存储空间的大小。
当获取到第一数据文件存储空间的大小时，在步骤S1022中，生成一虚拟数据文件。
在本公开实施例中，为了保证终端的存储器中具有存储该第一数据文件的存储空间，使得该第一数据文件的数据信息能够完整下载，并存储于终端内。为了保证具有能够存储该第一数据文件的存储空间，需要生成一虚拟数据文件，该虚拟数据文件同样占用该终端存储器的存储空间，只是该虚拟数据文件内部没有实质的数据信息，需要该第一数据文件下载完成后覆盖掉该虚拟数据文件，从而存储于该虚拟数据文件所占用的存储空间。
另外，该虚拟数据文件存储空间的大小与第一数据文件的存储空间的大小相同，从而，便于第一数据文件下载的数据信息能够完全存储于该虚拟数据文件所占用的存储空间内。
当生成所述虚拟数据文件时，在步骤S1023中，存储所述虚拟数据文件。
在步骤S1022中，生成与第一数据文件存储空间大小相同的虚拟数据文件，从而将该虚拟数据文件存储于该终端的存储器，通过存储该虚拟数据文件占用存储器的存储空间，且占用的存储空间即为用于存储第一数据文件对应数据信息的第一存储空间。
应用该方法，通过生成虚拟数据文件来占用终端存储器的存储空间，且该存储空间即为用于存储需要完成下载的第一数据文件对应存储的存储空间，从而保证第一数据文件能够完成下载。
图6是根据一示例性实施例示出的又一种数据下载方法的流程图，该数据下载方法包括以下步骤：
在步骤S1031中，提取所述第一数据文件对应的数据流。
当生成第一存储空间，或者生成虚拟数据文件并将该虚拟数据文件存储于终端存储器后，提取该第一数据文件的数据流，该数据流即对应该第一数据文件需要下载的数据预先存储的具有顺序的被读取一次数据的序列。
当提取到所述第一数据文件对应的数据流时，在步骤S1032中，获取所述数据流对应的数据信息。
在本公开实施例中，该数据流对应第一数据文件的数据信息，从而通过数据流依次获取对应的数据信息，直到该第一数据文件对应的所有数据信息全部被下载完成，从而将该第一数据文件下载的数据信息存储到该第一存储空间内，使得该第一数据文件完全覆盖该虚拟数据文件。
通过上述实施方式，生成与第一数据文件的存储空间大小相同的第一存储空间之后，根据第一数据文件的数据流获取相应的数据信息，从而将数据信息均存储于已经生成的第一存储空间内，避免被其他数据文件占用终端内的存储空间，有效解决数据文件下载过程中终端突然没有存储空间而无法继续下载数据信息，导致数据丢失的问题。
图7是根据一示例性实施例示出的一种数据下载的装置框图。该数据下载装置可以应用于终端中，例如：手机或平板电脑等。参考图7，该装置包括检测单元10、空间预留单元20和下载单元30。

其中，该空间预留单元20预留的第一存储空间的大小与该第一数据文件的存储空间大小相同，该第一存储空间用于存储该第一数据文件对应的数据信息，且该第一存储空间小于或等于终端剩余存储空间的大小。
当应用该装置时，如果用户需要下载数据文件，为了避免下载数据文件时其他数据文件占用终端存储器的存储空间，从而在终端中剩余存储空间中预留存储第一数据文件的第一存储空间，使得终端存储器中事先占用第一数据文件的存储空间，能够保证用户需要下载的第一数据文件下载成功，避免下载中途由于终端存储器没有存储空间无法下载、第一数据文件中数据信息丢失的情况。

在该装置中，数据下载指令的优先级可以按照数据文件的开始下载时间设定优先级，数据文件开始下载的时间越早，数据文件对应的数据下载指令的优先级越高。从而确定开始下载时间最早的数据文件为优先级最高的数据文件，从而针对该数据文件生成与之匹配的第一存储空间，用于存储该数据文件。
在图9所示实施例的基础上，如图10所示，该装置还可以包括：第二接收子单元14、第一提取子单元15、指令查询单元16和指令变更单元17。

指令查询单元16被配置为查询与所述身份识别标识相匹配的数据下载指令；
指令变更单元17被配置为将所述数据下载指令变更为优先级最高的第一数据下载指令。
其中，该数据下载指令中设置有优先级识别标识，且该优先级识别标识包括时间标识位和优先级标识位，且优先级标识位表示的优先级高于时间标识位表示的优先级，该时间标识位可以表示为数据文件开始下载的时间，且数据文件开始下载的时间越早优先级越高，该优先级标识位可以通过简单赋值的方式改变优先级。
基于上述图9之上，如图11所示，该优先级获取子单元12包括识别标识提取单元121和优先级确定单元122。其中，
该识别标识提取单元121被配置为提取所述数据下载指令的优先级识别标识，所述优先级识别标识包括时间标识位和优先级标识位，且所述优先级标识位的优先级高于所述时间标识位的优先级；
