应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
如图1所示，是本申请电子装置1较佳实施例的示意图。
在本实施例中，电子装置1可以是服务器、智能手机、平板电脑、个人电脑、便携计算机以及其他具有运算功能的电子设备。
该电子装置1包括：存储器11、处理器12、显示器13、网络接口14及 通信总线15。其中，网络接口14可选地可以包括标准的有线接口、无线接口(如WI-FI接口)。通信总线15用于实现这些组件之间的连接通信。
存储器11至少包括一种类型的可读存储介质。所述至少一种类型的可读存储介质可为如闪存、硬盘、多媒体卡、卡型存储器等的非易失性存储介质。在一些实施例中，所述存储器11可以是所述电子装置1的内部存储单元，例如该电子装置1的硬盘。在另一些实施例中，所述存储器11也可以是所述电子装置1的外部存储单元，例如所述电子装置1上配备的插接式硬盘，智能存储卡(Smart Media Card,SMC)，安全数字(Secure Digital,SD)卡，闪存卡(Flash Card)等。
在本实施例中，所述存储器11不仅可以用于存储安装于所述电子装置1的应用软件及各类数据，例如压缩工具调用程序10、各种类型的压缩工具16及各种类型、大小文件在各个压缩工具的压缩时间和压缩率的记录，还可以用于暂时地存储已经输出或者将要输出的数据。
处理器12在一些实施例中可以是一中央处理器(Central Processing Unit,CPU)，微处理器或其它数据处理芯片，用于运行存储器11中存储的程序代码或处理数据，例如执行压缩工具调用程序10的计算机程序代码等。
显示器13可以称为显示屏或显示单元。在一些实施例中显示器13可以是LED显示器、液晶显示器、触控式液晶显示器以及有机发光二极管(Organic Light-Emitting Diode，OLED)触摸器等。显示器13用于显示在电子装置1中处理的信息以及用于显示可视化的工作界面，如显示压缩模式选择页面。
优选地，该电子装置1还可以包括用户接口，用户接口可以包括输入单元比如键盘(Keyboard)、语音输出装置比如音响、耳机等，可选地用户接口还可以包括标准的有线接口、无线接口。
在图1所示的装置实施例中，作为一种计算机存储介质的存储器11中存储压缩工具调用程序10的程序代码，处理器12执行压缩工具调用程序10的程序代码时，实现如下步骤：
解析步骤：响应用户每次启动压缩文件的操作，解析待压缩文件的类型及大小，记录用户选择的压缩模式及压缩工具；
记录步骤：压缩完成后，记录在该压缩模式下，该压缩工具针对该类型、 大小的文件的压缩率及压缩时间；
计算步骤：每隔预设周期，根据预设的推荐值计算公式计算每种压缩模式下，每种压缩工具针对每种类型文件关于压缩率的推荐值或压缩时间的推荐值；
接收步骤：接收用户压缩文件的请求及用户选择的压缩模式；
调用步骤：在该压缩模式下，选择压缩率的最大推荐值或压缩时间的最大推荐值对应的压缩工具，自动调用选择的压缩工具对文件执行压缩操作。
本实施例中，压缩工具调用程序10响应用户每次启动压缩文件的操作，解析待压缩文件的类型及大小，记录用户选择的压缩模式及压缩工具。例如，用户压缩图片文件时，压缩工具调用程序自动解析待压缩的图片文件的类型及占用空间大小，并记录该用户所选择的压缩模式及压缩工具。其中，文件类型包括：多媒体文件(如音频文件、视频文件、图像文件等)、文档类文件(如doc文件、txt文件、xls文件等)及可执行文件(如exe文件安装包等)。对于不同类型及大小的文件，不同的压缩工具压缩文件的压缩率和压缩时间各不相同。例如，fastlz、lz4针对2M的txt文件的压缩率分别为14％、18％，压缩时间分别为4s、6s。压缩模式包括极限压缩模式和极速压缩模式。其中，极限压缩模式主要侧重于文件的压缩率，极速压缩模式主要侧重于文件的压缩时间。
压缩完成后，压缩工具调用程序10记录在该压缩模式下，该压缩工具针对该类型、大小的文件的压缩率及压缩时间。例如，用户选择的是极限压缩模式，调用的压缩工具是WinRAR，则压缩完成后，记录压缩模式、压缩工具、文件类型、文件大小、压缩率及压缩时间分别为：极限压缩模式-WinRAR-图片文件-4M-28％-10s。其中，所述压缩工具包含：fastlz、lz4、snappy、deflate、WinRAR、WinZip、zlib等压缩工具的一种或几种。
压缩工具调用程序10每隔预设周期，根据预设的推荐值计算公式计算每种压缩模式下，每种压缩工具针对每种类型文件关于压缩率的推荐值或压缩时间的推荐值。例如，每个月的最后一天晚上，压缩工具调用程序自动利用预设的推荐值计算公式，根据该月记录的每种类型文件在每种压缩工具的压缩率和压缩时间，计算每个文件在每种压缩工具的推荐值。
其中，所述预设的推荐值计算公式包括：
极限压缩模式下，推荐值计算公式为：
其中Y
1代表某种类型文件在某种压缩工具的压缩率推荐值，X
i代表该类型文件预设周期内在该压缩工具下的压缩率，n为正整数，代表预设周期内利用该压缩工具压缩过的该类型文件的数量。例如，预设周期内，WinRAR针对doc文件的压缩率为30％、28％，则利用推荐值计算公式：
算出doc文件在WinRAR的压缩率推荐值为71。
极速压缩模式下，推荐值计算公式为：
其中Y2代表某种类型文件在某种压缩工具的压缩时间推荐值，M
ij/N
ij代表预设周期内，该类型文件在所有压缩工具下压缩时间与文件大小之比，M
i/N
j代表预设周期内，该类型文件在某压缩工具下压缩时间与文件大小之比，m为正整数，代表压缩工具压的数量，n为正整数，代表预设周期内利用该压缩工具压缩过的该类型文件的数量。假设压缩工具中只有WinRAR和WinZip两种压缩工具，针对4M的jpg图片文件，压缩时间分别为8s、4s，则利用推荐值计算公式：
算出jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40。
当用户需要压缩多媒体文件时，在压缩模式选择页面选择适合的压缩模式。压缩工具调用程序10接收用户压缩文件的请求及用户选择的压缩模式。例如，接收4M的jpg图片文件和用户选择的极速压缩模式。
压缩工具调用程序10根据用户选择的压缩模式，自动调用压缩率推荐值最大或压缩时间推荐值最大的压缩工具对待压缩文件执行压缩操作。例如，在极速压缩模式下，假设待压缩文件为4M的jpg图片文件且压缩工具中只有WinRAR和WinZip两种压缩工具，4M的jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40，则调用WinZip对4M的jpg图片文件进行压缩。
在另一个实施例中，还可以向用户展示在选择的压缩模式下，待压缩文件在每种压缩工具的压缩率推荐值或压缩时间推荐值，用户根据业务场景选择合适的压缩工具执行压缩操作。例如，在极速压缩模式下，显示4M的jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40，即使WinRAR的压缩时间较长，但是若用户觉得WinRAR压缩的失真较小，依然可以选择WinRAR对文件进行压缩。
上述实施例提出的压缩工具调用方法，根据用户选择的压缩模式查询待 压缩文件在每个压缩工具中的压缩率推荐值或压缩时间推荐值，自动调用最优的压缩工具对文件进行压缩处理，减少工作人员的手动压缩操作，提高业务处理效率。
如图2所示，是图1中压缩工具调用程序10较佳实施例的模块示意图。本申请所称的模块是指能够完成特定功能的一系列计算机程序指令段。
在本实施例中，压缩工具调用程序10包括：解析模块110、记录模块120、计算模块130、接收模块140、调用模块150，所述模块110-150所实现的功能或操作步骤均与上文类似，此处不再详述，示例性地，例如其中：
解析模块110，用于响应用户每次启动压缩文件的操作，解析待压缩文件的类型及大小，记录用户选择的压缩模式及压缩工具；
记录模块120，用于压缩完成后，记录在该压缩模式下，该压缩工具针对该类型、大小的文件的压缩率及压缩时间；
计算模块130，用于每隔预设周期，根据预设的推荐值计算公式计算每种压缩模式下，每种压缩工具针对每种类型文件关于压缩率的推荐值或压缩时间的推荐值；
接收模块140，用于接收用户压缩文件的请求及用户选择的压缩模式；
调用模块150，用于在该压缩模式下，选择压缩率的最大推荐值或压缩时间的最大推荐值对应的压缩工具，自动调用选择的压缩工具对文件执行压缩操作。
如图3所示，是本申请压缩工具调用方法第一实施例的流程图。
在本实施例中，处理器12执行存储器11中存储的压缩工具调用程序10的计算机程序时实现压缩工具调用方法包括：步骤S10-步骤S50：
步骤S10，如图7所示，是本申请压缩工具调用方法的应用环境示意图，压缩工具调用程序10响应用户每次启动压缩文件的操作，解析待压缩文件的类型及大小，记录用户选择的压缩模式及压缩工具。其中，压缩工具存储于压缩工具库16。例如，用户压缩图片文件时，压缩工具调用程序自动解析待压缩的图片文件的类型及占用空间大小，并记录该用户所选择的压缩模式及压缩工具。其中，文件类型包括：多媒体文件(如音频文件、视频文件、图 像文件等)、文档类文件(如doc文件、txt文件、xls文件等)及可执行文件(如exe文件安装包等)。对于不同类型及大小的文件，不同的压缩工具压缩文件的压缩率和压缩时间各不相同。例如，fastlz、lz4针对2M的txt文件的压缩率分别为14％、18％，压缩时间分别为4s、6s。压缩模式包括极限压缩模式和极速压缩模式。其中，极限压缩模式主要侧重于文件的压缩率，极速压缩模式主要侧重于文件的压缩时间。
步骤S20，压缩完成后，压缩工具调用程序10记录在该压缩模式下，该压缩工具针对该类型、大小的文件的压缩率及压缩时间。例如，用户选择的是极限压缩模式，调用的压缩工具是WinRAR，则压缩完成后，记录压缩模式、压缩工具、文件类型、文件大小、压缩率及压缩时间分别为：极限压缩模式-WinRAR-图片文件-4M-28％-10s。其中，所述压缩工具包含：fastlz、lz4、snappy、deflate、WinRAR、WinZip、zlib等压缩工具的一种或几种。
步骤S30，压缩工具调用程序10每隔预设周期，根据预设的推荐值计算公式计算每种压缩模式下，每种压缩工具针对每种类型文件关于压缩率的推荐值或压缩时间的推荐值。例如，每个月的最后一天晚上，压缩工具调用程序自动利用预设的推荐值计算公式，根据该月记录的每种类型文件在每种压缩工具的压缩率和压缩时间，计算每个文件在每种压缩工具的推荐值。
其中，所述预设的推荐值计算公式包括：
极限压缩模式下，推荐值计算公式为：
其中Y
1代表某种类型文件在某种压缩工具的压缩率推荐值，X
i代表该类型文件预设周期内在该压缩工具下的压缩率，n为正整数，代表预设周期内利用该压缩工具压缩过的该类型文件的数量。例如，预设周期内，WinRAR针对doc文件的压缩率为30％、28％，则利用推荐值计算公式：
算出doc文件在WinRAR的压缩率推荐值为71。
极速压缩模式下，推荐值计算公式为：
其中Y
2代表某种类型文件在某种压缩工具的压缩时间推荐值，M
ij/N
ij代表预设周期内，该类型文件在所有压缩工具下压缩时间与文件大小之比，M
i/N
i代表预设周期内，该类型文件在某压缩工具下压缩时间与文件大小之比，m为正整数，代表压缩工具压的数量，n为正整数，代表预设周期内利用该压缩工具压缩过的该类型文件的数量。假设压缩工具中只有WinRAR和 WinZip两种压缩工具，针对4M的jpg图片文件，压缩时间分别为8s、4s，则利用推荐值计算公式：
算出jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40。
步骤S50，压缩工具调用程序10根据用户选择的压缩模式，从压缩工具集16中自动调用压缩率推荐值最大或压缩时间推荐值最大的压缩工具对待压缩文件执行压缩操作。例如，在极速压缩模式下，假设待压缩文件为4M的jpg图片文件且压缩工具中只有WinRAR和WinZip两种压缩工具，4M的jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40，则调用WinZip对4M的jpg图片文件进行压缩。
在另一个实施例中，如图4所示，是本申请压缩工具调用方法第二实施例的流程图。步骤S50还可以是向用户展示在选择的压缩模式下，待压缩文件在每种压缩工具的压缩率推荐值或压缩时间推荐值，用户根据业务场景选择合适的压缩工具执行压缩操作。例如，在极速压缩模式下，显示4M的jpg图片文件在WinRAR和WinZip的压缩时间推荐值分别为10、40，即使WinRAR的压缩时间较长，但是若用户觉得WinRAR压缩的失真较小，依然可以选择WinRAR对文件进行压缩。
本实施例提出的压缩工具调用方法，通过为用户提供压缩模式，在用户选择的压缩模式下，根据待压缩文件的在每个压缩工具的压缩率推荐值或压缩时间推荐值，调用最适合该业务场景的压缩工具对文件执行压缩操作，节省文件存储空间，提高压缩性能。
如图5所示，是本申请压缩工具调用方法第三实施例的流程图。
在本实施例中，压缩工具调用方法包括：步骤S10-步骤S70。其中步骤S10-步骤S40与第一实施例中的内容大致相同，这里不再赘述。
步骤S50，在用户选择的压缩模式下，压缩工具调用程序10根据每种压缩工具对这种类型的文件的压缩率推荐值或压缩时间推荐值生成一个数值范围，在该数值范围内产生一个随机数。例如，在极速压缩模式下，2Mtxt文件在fastlz、lz4、snappy三种压缩工具中的压缩时间推荐值分别为10、20、60，则压缩工具调用程序10生成的随机数最小值为0，最大值为90，并产生一个随机数，假设该随机数为30。
步骤S60，压缩工具调用程序10根据产生的随机数，计算该随机数与每种压缩工具的推荐值的差值。例如，随机数为30，与2Mtxt文件在fastlz、lz4、snappy三种压缩工具中的压缩时间推荐值(10、20、60)的差值分别为20、10、30。
步骤S70，压缩工具调用程序10从压缩工具集16中选择最小差值对应的压缩工具，自动调用该压缩工具对文件执行压缩操作。该自动模式适用于大量文件压缩申请。例如，根据随机数30，与fastlz、lz4、snappy三种压缩工具中的压缩时间推荐值的差值分别为20、10、30，自动选择差值最小的压缩工具(lz4)对文件进行压缩。
在另一个实施例中，如图6所示，是本申请压缩工具调用方法第四实施例的流程图。步骤S70还可以是根据差值从小到大的顺序给每种压缩工具分配不同的推荐级别，并展示给用户参考选择。该推荐模式适用于少量文件压缩请求。例如，根据差值为20、10、30，给lz4分配最高推荐级别，给fastlz分配次高推荐级别，给snappy分配最低推荐级别，用户可根据推荐级别从压缩工具集16中选择压缩工具进行文件压缩。
相比于第一实施例，本实施例提出的压缩工具调用方法，根据待压缩文件在每种压缩工具的推荐值生成一个数值范围，并在范围内产生一个随机数，然后采取推荐值结合随机数的方式，使得推荐值较小的压缩工具也有一定几率被调用执行压缩操作，减少推荐值较大的压缩工具的负担。
此外，本申请实施例还提出一种计算机可读存储介质，所述计算机可读存储介质中包括压缩工具调用程序10，所述压缩工具调用程序10被处理器执行时实现如下操作：

调用步骤：选择最小差值对应的压缩工具，自动调用选择的压缩工具对文件执行压缩操作。
