Description

文档在线预览方法及装置 技术领域
本公开涉及互联网技术领域，具体而言，涉及一种文档在线预览方法以及一种文档在线预览装置。
背景技术
随着互联网的迅速发展，人们可以从互联网上轻松下载各种文档到本地进行浏览，但需本地安装相应文档的阅读软件。另外，下载文档尤其是大文档需要增加额外的等待时间，用户体验性差。所以，目前越来越多的网站趋向于在线预览文档，文档在线预览技术常规做法是先进行转换，后进行预览，但大都存在性能较低，转换率不高等情况。
目前两种常用的文档在线预览方案如下：
前端转换并在线预览，这种文档在线预览实现方法是当用户点击文档进行预览时，触发后台程序转换文档。这种实现方法的优点是：文档不必全部转换，只有当用户需要查看文档的时候才进行转换，降低了服务器的压力；缺点是：当文档比较大的时候，可能会增加用户的等待时间，与下载几乎无分别，用户体验较差，并且，在高并发下大文档转换极易发生失败。
后端异步转换文档，这种文档在线预览方法是当用户上传文档的时候进行异步转换，前台用户点击文档时预览文档。这种实现方法的优点是：前台预览文档的时候速度快、体验好；缺点是：所有文档都需要进行转换，服务器压力较大，并且，对于大文档也同样存在转化失败的问题。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

本示例实施方式中首先提供了一种文档在线预览方法。参考图1中所示，所述文档在线预览方法可以包括以下步骤：
S110.根据待预览内容的主键在缓存服务器中查询与所述主键关联的数据是否存在；
S120.如果查询到与所述主键关联的数据存在，则从所述缓存服务器中获取与所述主键关联的数据，并将与所述主键关联的数据发送给应用服务器；

S140.在判断所述键值浏览量的值不为零时，根据所述主键从云存储服务器获取待预览内容并提供至应用服务器；
S150.更新所述键值浏览量，并将更新后的键值浏览量存储在所述缓存服务器中；
S160.所述应用服务器接收所述待预览内容以供用户预览。
本示例实施方式中的文档在线预览方法，一方面，采用文档分页转换预览的方式，减少了整个文档的转换所需时间；另一方面，通过采用缓存、队列转换的方式为用户提供需要预览的文档，提高了整体系统的性能，适合用户高并发访问预览；再一方面，通过在用户选择预览文档时才需要进行转换触发方式，使得服务器不用转换全部的文档，减轻了对服务器的压力。
更进一步的，通过根据文档页面的访问浏览量和最近访问时间定时清理缓存的方式，提升了用户预览文档的速度。
下面，将对本示例实施方式中上述文档在线预览方法的各步骤进行详细的说明。
在步骤S110中，根据待预览内容的主键在缓存服务器中查询与所述主键关联的数据是否存在。
在本示例实施方式中，所述待预览内容可以包括用户所需要查看的某一个文档的某一页或者某几页；所述主键可以包括一个或者多个字段；所述待预览内容的主键可以包括文档编号和文档对应的页码；所述缓存服务器可以是用户判断用户所请求预览的文档和该文档当前页是否已经存在转换的服务器；举例而言：
在用户选择某一个文档并对该文档中的某一页进行预览时，首先向应用服务器发送请求；应用服务器接收用户请求，将该文档编号(例如可以是：JDZL00001)和该文档对应的页码(例如可以是：第一页)作为联合主键key(即key为：JDZL00001-1，简称主键)，根据主键在缓存服务器上查找与主键关联的数据是否存在。此外，在本公开的其他示例性实施例中，也可以根据情况以其他方式进行查找，本示例性实施方式中对此不做特殊限定。
在步骤S120中，如果查询到与所述主键关联的数据，则从所述缓存服务器中获取与所述主键关联的数据，并将与所述主键关联的数据发送给应用服务器。
在本示例实施方式中，与所述主键关联的数据可以包括主键、键值浏览量以及访问时间等；所述键值浏览量可以用于表示待预览文档中某一页的浏览次数；所述访问时间可以包括最近一次的浏览时间；但本示例实施方式对与所述主键关联的数据不做特殊限制，在本公开的其他示例性实施例中，其也可以包括其他数据。
本示例实施方式中，在经过查询确定与所述主键关联的数据存在时，举例而言，首先应用服务器查询在所述缓存服务器中查询是否存在需要预览的文档以及该文档中的某一页对应的数据，如果应用服务器在缓存服务器中查询到需要预览的文档以及该文档中的某一页对 应的数据存在，则直接从缓存服务器中获取该文档以及该文档中的某一页和该页对应的数据，例如浏览量以及最近一次的浏览时间，然后将该数据发送给应用服务器。
在本示例的另外一种实施方式中，如果应用服务器在缓存服务器中查询到需要预览的文档以及该文档中的某一页对应的数据不存在，则从数据库中获取与所述主键关联的数据；以及如果所述数据库中存在与所述主键关联的数据，则可以将与所述主键关联的数据发送到所述缓存服务器；如果所述数据库中不存在与所述主键关联的数据，则在所述数据库中创建一与所述主键关联的数据初始值并发送到所述缓存服务器，所述数据初始值中键值浏览量为零，所述数据初始值中访问时间为当前访问时间。举例而言，如果应用服务器在缓存服务器中查询到需要预览的文档以及该文档中的某一页不存在，则从数据库中获取该文档以及该文档中对应的页码和该页的浏览量以及最近一次的浏览时间，然后发送给应用服务器；如果数据库中不存在该文档以及该文档中对应的页和该页的浏览量以及最近一次的浏览时间，则在数据库中创建该文档以及该文档中对应的页和该页的浏览量以及最近一次的浏览时间，然后发送给应用服务器；所述浏览量为零，所述浏览时间为当前时间。
在步骤S130中，所述应用服务器接收与所述主键关联的数据后，对与所述主键关联的数据中包含的所述主键的键值浏览量进行判断。
举例而言，应用服务器接收该文档以及该文档中对应的页和该页的浏览量以及最近一次的浏览时间后，对所述浏览量就行判断。
在步骤S140中，在判断所述键值浏览量的值不为零时，根据所述主键从云存储服务器获取待预览内容并提供至应用服务器；以及，更新所述键值浏览量，并将更新后的键值浏览量存储在所述缓存服务器中。
在判断所述浏览量的值为零时，对预览内容进行转换，并将转换后的预览内容上传至所述云存储服务器；并且，在原有的浏览量的基础上加1，然后将更新后的浏览量存储在缓存服务器中。参考图2所示，本示例实施方式中，对预览内容进行转换可以包括下述步骤S202～S206。其中：
在步骤S202中，将所述主键写入需要转换的队列等待转换。
在步骤S204中，从所述队列中获取需要等待转换的主键并根据所述主键从所述云存储服务器获取待预览内容进行转换。举例而言：
本示例实施方式中，可以采用单线程或多线程的方式，从所述队列中获取需要等待转换的主键并根据所述主键从所述云存储服务器获取待预览内容进行转换，但本示例实施方式不以此为限。此外，在本公开的其他示例性实施例中，也可以根据情况以其他方式从队列中获取需要等待转换的主键，本示例性实施例中对此不做特殊限定。
其中，上述线程可以被理解为：轻量级进程(Lightweight Process，LWP)，是程序执行流的最小单元；一个标准的线程由线程ID，当前指令指针(PC)，寄存器集合和堆栈组成；队列可以被理解为：一种特殊的线性表，特殊之处在于它只允许在表的前端(front)进行删除操作，而在表的后端(rear)进行插入操作，和栈一样，队列是一种操作受限制的线性表，进行插入操作的端称为队尾，进行删除操作的端称为队头；但本示例实施方式不以此为限。
在本示例实施方式中，待预览内容转换以后生成的格式可以包括：.html、.doc、.docx、.xls、.xlsx、.ppt、.pptx、.txt或者是.pdf等等，但本示例实施方式不以此为限。
在步骤S206中，完成所述预览内容转换时，将所述缓存服务器中的键值浏览量修改为1，从而便于后续流程的进行。
此外，在本示例实施方式中，对所述预览内容进行转换时，还可以提供一用户等待标识；完成所述预览内容的转换时，取消所述用户等待标识；如果超过设定的超时时间，则提示转换失败，需要重新进行转换。通过采用用户等待标识，使得用户可以很明确的看出文档的具体转换情况，提高了用户体验。
在步骤S150中，所述应用服务器接收所述待预览内容以供用户预览。
举例而言，应用服务器在接收到该页的待预览内容以后，会将该页的待预览内容发送至终端，用户通过终端进行预览最终的结果。在本示例实施方式中，所述终端可以包括：手机、平板电脑、笔记本电脑、台式电脑、游戏机、PDA等各种具备显示屏幕的电子设备。
在另一些示例实施方式中，参考图3所示，所述文档在线预览方法还可以包括步骤S310以及步骤S320。其中：
在步骤S310中，定时删除所述缓存服务器中所述键值浏览量小于第一预设值的与所述主键关联的数据；在步骤S320中，定时删除所述缓存服务器中访问时间大于第二预设值的与所述主键关联的数据。详细而言：为了充分利用缓存服务器内存以及满足系统的高性能，用户浏览文档的页面内容需要尽可能的从缓存服务器中获得，因此，可以定时的从缓存服务器中将浏览量比较低的文档和页码删除；也可以定时的从缓存服务器中将访问时间距离现在比较久远的文档和页码删除；并将上述删除的文档和页码保存到数据库中；通过上述方式，同时保证了缓存在缓存服务器中的数据具有最大活性。
下述为本发明装置实施例，可以用于执行本发明方法实施例。对于本发明装置实施例中未披露的细节，请参照本发明方法实施例。
本示例实施方式中还提供了一种文档在线预览装置，参考图4中所示，所述文档在线预览装置可以包括：数据查询模块410、第一数据获取模块420、键值浏览量判断模块430、预览内容获取模块440、更新存储模块450以及预览内容接收模块460；其中：
数据查询模块410：用于根据待预览内容的主键在缓存服务器中查询与所述主键关联的数据是否存在；
第一数据获取模块420：用于如果查询到与所述主键关联的数据存在，则从所述缓存服务器中获取与所述主键关联的数据，并将与所述主键关联的数据发送给应用服务器；
键值浏览量判断模块430：用于所述应用服务器接收与所述主键关联的数据后，对与所述主键关联的数据中包含的所述主键的键值浏览量进行判断；
预览内容获取模块440：用于在判断所述键值浏览量的值不为零时，根据所述主键从云存储服务器获取待预览内容并提供至应用服务器；以及，
更新存储模块450：用于更新所述键值浏览量，并将更新后的键值浏览量存储在所述缓 存服务器中；
预览内容接收模块460：用于所述应用服务器接收所述待预览内容以供用户预览。

在另一些实施例中，还包括：
第二数据获取模块：用于如果查询到与所述主键关联的数据不存在，则从数据库中获取与所述主键关联的数据；以及
第一数据发送模块：用于如果所述数据库中存在与所述主键关联的数据，则将与所述主键关联的数据发送到所述缓存服务器；
第二数据发送模块：如果所述数据库中不存在与所述主键关联的数据，则在所述数据库中创建一与所述主键关联的数据初始值并发送到所述缓存服务器，所述数据初始值中键值浏览量为零，所述数据初始值中访问时间为当前访问时间。
