背景技术
随着例如手机的移动端的快速发展，移动端经常需要下载或更新文件；而针对经下载后存储在移动端本地的文件，经过一段时间后，如果这个文件过期了，则需要删除；如果这个文件没有过期，则需要正常使用该文件，不应当删除；针对上述情况，由于移动端的存储容量是有限的，因此需要对这些文件进行管理。
例如，对于存储在移动端本地的N个文件，而N个文件中的M个文件是可用的，是不需要删除的；现有技术中，通常是对全部的N个文件都删除，或者都不删除。因此，现有技术至少存在以下技术缺陷：N个文件都不删除会占用移动端大量的存储空间，影响移动端的使用；而全部都删除，会导致可用的M个文件在下次使用时需要从服务端重新下载，浪费了流量。
发明内容
针对现有技术中存在的上述缺陷，本发明提供一种更新文件的方法、装置和设备。
本发明的一方面提供一种更新文件的方法，包括：S1，向服务端发送获取配置文件数据的请求消息后，接收服务端返回的配置文件数据；其中，配置文件是预先通过服务端生成的用于存储待更新文件信息的文本类型文件；S2，对所述配置文件数据进行解析，获取所述配置文件数据中至少一个待更新文件的名称和MD5值；其中，所述MD5值用于校验文件信息是否一致；S3，若存在名称及MD5值均相同的待更新文件和本地文件，则取消下载所述待更新文件，并保留所述本地文件。
其中，所述S1中向服务端发送获取配置文件数据的请求消息的步骤进一步包括：S11，获取配置文件下载链接的地址，根据所述地址向服务端发送所述请求消息；S12，接收服务端返回的错误码，若所述错误码为0，则请求成功，并接收服务端返回的所述配置文件数据。
其中，所述步骤S2进一步包括：S21，对所述配置文件数据进行解析，获取数据字典；S22，对所述数据字典进行取值处理，获取包含至少一个元素的待更新数组；其中，每个所述元素至少记录一个待更新文件的名称和MD5值。
其中，所述步骤S3前还包括：通过循环遍历获取本地文件的名称，并将所述本地文件的名称存储至本地数组；获取所述本地文件的名称所对应的路径；根据所述路径对所述本地文件进行MD5加密，获取所述本地文件对应的MD5值。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
图1为本发明实施例提供的更新文件的方法的流程示意图，如图1所示，包括：S1，向服务端发送获取配置文件数据的请求消息后，接收服务端返回的配置文件数据；其中，配置文件是预先通过服务端生成的用于存储待更新文件信息的文本类型文件；S2，对所述配置文件数据进行解析，获取所述配置文件数据中至少一个待更新文件的名称和MD5值；其中，所述MD5值用于校验文件信息是否一致；S3，若存在名称及MD5值均相同的待更新文件和本地文件，则取消下载所述待更新文件，并保留所述本地文件。
其中，配置文件为在服务端预先设置的文本类型文件；该文件记录了待更新文件的信息，至少包括待更新文件的名称或ID、下载链接和MD5值；本发明实施例中，移动端可以通过发送请求消息，获取到配置文件中的数据。
其中，MD5即Message-Digest Algorithm 5(信息-摘要算法5)，用于确保信息传输完整一致；是计算机广泛使用的杂凑算法之一(又译摘要算法、哈希算法)，主流编程语言普遍已有MD5实现；将数据(如汉字)运算为另一固定长度值，是杂凑算法的基础原理，MD5的前身有MD2、MD3和MD4。本发明实施例选择MD5作为确认文件信息是否相同的手段，但本发明实施例的保护范围不限于此。
在步骤S1中，移动端首先向服务端发送一个请求消息，该请求消 息中携带了请求获取配置文件数据的信息；服务端接收到请求消息后，可以根据该请求消息向移动端返回发送配置文件数据。
具体可以通过在移动端增加文件配置接口功能函数cheackCustomEmblemConfig，通过该函数实现移动端判断下载哪些待更新文件(压缩包文件)。
在步骤S2中，根据步骤S1中得到的配置文件数据，移动端可以对配置文件数据进行进一步解析；获取配置文件中携带的信息，该信息包括至少一个待更新文件的相关信息，相关信息至少包括文件名称和MD5值。例如待更新文件为压缩包文件，则解析后包括该压缩包的名称和压缩包对应的MD5值。
在步骤S3中，根据步骤S2中得到的待更新文件的名称和MD5值，与本地文件的名称和MD5值进行比较，具体如下：
如果一个本地文件与一个待更新文件的MD5值和名称都相同，说明该待更新文件和该本地文件的信息没有改变，该本地文件不需要更新，那么就取消下载这个待更新文件；同样的，在移动端不用删除这个本地文件，对该本地文件进行保留。
相应地，对于除了取消下载的待更新文件之外的其他待更新文件应当进行下载；对除了保留的本地文件之外的其他本地文件应当进行删除。
本发明实施例提供的更新文件的方法，通过获取待更新文件的名称和MD5值，并判断与本地文件是否相同后进行相应地操作，实现了对本地文件的部分保留和对待更新文件的部分下载，节约了移动端进行文件更新时消耗的流量，释放了移动端本地的存储空间，使本地文件与服务端保持一致。
在上述任一实施例的基础上，所述S1中向服务端发送获取配置文 件数据的请求消息的步骤进一步包括：S11，获取配置文件下载链接的地址，根据所述地址向服务端发送所述请求消息；S12，接收服务端返回的错误码，若所述错误码为0，则请求成功，并接收服务端返回的所述配置文件数据。
在步骤S11中，移动端首先获取到配置文件的下载链接的地址，再拿这个地址去服务端请求配置文件的数据。
在步骤S12中，在步骤S11中请求数据后，服务端会向移动端发送一个错误码告知本次网络请求是成功还是失败；如果成功，则错误码为0，并且服务端会返回配置文件数据。
在上述任一实施例的基础上，所述步骤S2进一步包括：S21，对所述配置文件数据进行解析，获取数据字典；S22，对所述数据字典进行取值处理，获取包含至少一个元素的待更新数组；其中，每个所述元素至少记录一个待更新文件的名称和MD5值。
其中，数据字典是指对数据的数据项、数据结构、数据流、数据存储、处理逻辑、外部实体等进行定义和描述。
在步骤S21中，移动端对接收到的配置文件数据进行解析，解析后成为了数据字典；之后对数据字典执行相关的处理操作。
在步骤S22中，根据步骤S21中获取的数据字典，对数据字典进行取值操作，例如使用objectForKey方法从数据字典中取出一个待更新数组newListArray；这个待更新数组存储了至少一个元素，每个元素记录了一个待更新文件的名称(ID或压缩包的名称)和MD5值；另外，还可以包括待更新文件的下载链接。
在上述任一实施例的基础上，所述步骤S3前还包括：通过循环遍历获取本地文件的名称，并将所述本地文件的名称存储至本地数组；获取所述本地文件的名称所对应的路径；根据所述路径对所述本地文 件进行MD5加密，获取所述本地文件对应的MD5值。
具体地，可以预先创建一个本地数组localZipFile，用于存储本地文件的信息；可以使用一个循环遍历已经存储在移动端的本地文件，获取每个本地文件(压缩包)的名称，并且将各个名称存储在本地数组中。
然后根据本地文件的名称file，获取本地文件对应的存储路径filePath；根据存储路径对本地文件进行MD5加密，获取到本地文件分别对应的MD5值；并且，可以将MD5值存储到本地数组中对应的本地文件的名称下。
在上述任一实施例的基础上，所述步骤S3进一步包括：S31，遍历所述待更新数组，将所述待更新数组中的每个待更新文件与所述本地数组中的本地文件进行比较；若存在名称及MD5值均相同的待更新文件和本地文件，则将所述本地文件的名称添加至预先创建的取消下载数组，并保留所述本地文件；S32，遍历所述待更新数组，对所述待更新数组中的每个待更新文件进行判断；若所述待更新文件具有对应的下载链接，且所述待更新文件的名称不包含在所述取消下载数组中，则根据所述下载链接下载所述待更新文件，并删除名称不包含在所述取消下载数组中的本地文件。
在步骤S31中，遍历待更新数组，将每个待更新文件的名称和MD5值都比文本文件的名称和MD5值比较一遍；如果待更新文件和本地文件的名称和MD5值的名称都相同，说明文件信息没有改变，本地文件不需要更新，就把相同的名称存储在预先创建的取消下载数组doNotNeedDownLoadRoomIDArray。遍历后，取消下载数组就保存了所有不需要下载的待更新文件的名称，相应地，也是所有需要保留的本地文件的名称。
在步骤S32中，对待更新数组执行再执行一次遍历操作，首先判 断每个待更新文件名称是否有对应的下载链接zipUrl，如果存在，则证明该待更新文件是可下载的；再判断更新文件的名称是否包含在取消下载数组中，如果不包含，则说明本地没有该待更新文件，需要对该待更新文件进行下载；否则，无需下载。经过遍历后，就能够对所有本地不存在的待更新文件完成下载操作。
另外，取消下载数组中同样保存了需要保留的本地文件的名称，那么对于取消下载数组中不包含名称的本地文件执行删除操作。
通过数组的双层循环遍历能够有效节约代码量，提高性能。
在上述任一实施例的基础上，所述步骤S22后还包括：S23，判断所述待更新数组是否为数组类型，若不是数组类型，则终止文件更新。
具体地，获取到待更新数组后，应当判断是否为数组类型，例如使用判断方法isKindOfClass，如果其真实类型不是数组类型，则应当终结更新方法，这样能够避免之后对数组的处理由于其并不是数组类型而造成运行时的崩溃。
在上述任一实施例的基础上，所述S11中获取配置文件下载链接的地址的步骤进一步包括：获取配置文件下载链接的基础地址和固定地址；拼接所述基础地址和所述固定地址，获取所述配置文件下载链接的地址。
具体地，为了读取配置文件，需要获得配置文件的下载链接的地址；该地址包括前半部分的基础地址(baseUrl)和后半部分的固定地址(Url)；其中，baseUrl是各种环境对应的地址，其在不同的环境(测试环境或者正式环境)不一样；Url通常是比较固定的；将baseUrl和Url拼接为一个完整的下载链接的地址(requestStr)，就可以通过requestStr去服务端请求配置文件数据。
图2为本发明实施例提供的更新文件的装置的结构示意图，如图 2所示，包括：接收模块201，用于向服务端发送获取配置文件数据的请求消息后，接收服务端返回的配置文件数据；其中，配置文件是预先通过服务端生成的用于存储待更新文件信息的文本类型文件；获取模块202，用于对所述配置文件数据进行解析，获取所述配置文件数据中至少一个待更新文件的名称和MD5值；其中，所述MD5值用于校验文件信息是否一致；更新模块203，用于若存在名称及MD5值均相同的待更新文件和本地文件，则取消下载所述待更新文件，并保留所述本地文件。
具体地，接收模块201首先向服务端发送一个请求消息，该请求消息中携带了请求获取配置文件数据的信息；服务端接收到请求消息后，可以根据该请求消息向接收模块201返回发送配置文件数据。
接收模块201具体可以通过增加文件配置接口功能函数cheackCustomEmblemConfig，通过该函数实现判断下载哪些待更新文件(压缩包文件)。
具体地，获取模块202根据接收模块201中得到的配置文件数据，获取模块202可以对配置文件数据进行进一步解析；获取配置文件中携带的信息，该信息包括至少一个待更新文件的相关信息，相关信息至少包括文件名称和MD5值。例如待更新文件为压缩包文件，则解析后包括该压缩包的名称和压缩包对应的MD5值。
具体地，更新模块203根据获取模块202中得到的待更新文件的名称和MD5值，与本地文件的名称和MD5值进行比较，具体如下：
如果一个本地文件与一个待更新文件的MD5值和名称都相同，说明该待更新文件和该本地文件的信息没有改变，该本地文件不需要更新，那么更新模块203就取消下载这个待更新文件；同样的，更新模块203不用删除这个本地文件，对该本地文件进行保留。
相应地，对于除了取消下载的待更新文件之外的其他待更新文件， 更新模块203应当进行下载；对除了保留的本地文件之外的其他本地文件，更新模块203应当进行删除。
本发明实施例提供的更新文件的装置，通过获取待更新文件的名称和MD5值，并判断与本地文件是否相同后进行相应地操作，实现了对本地文件的部分保留和对待更新文件的部分下载，节约了移动端进行文件更新时消耗的流量，释放了移动端本地的存储空间，使本地文件与服务端保持一致。

在上述任一实施例的基础上，所述获取模块202还包括：终止单元，用于判断所述待更新数组是否为数组类型，若不是数组类型，则终止文件更新。
