技术领域
本申请涉及文件同步领域，具体地，涉及一种用于文件同步的方法、接收方设备及系统。
背景技术
在当今的信息时代，已然离不开文件的传输。在现有的文件传输过程中，通常都是将待传输的文件整体作为一个独立的传输部分从发送端传输到目的接收端。然而，当待传输的文件较大时，现有的文件传输方法不仅会出现传输效率差的情况，还可能出现文件传输不稳定而导致文件传输失败的问题。并且，随着文件的大小不断变大，文件传输的时间相应地就会增加，同时成功传输的几率也会受到影响，从而无法保证较大文件的高效稳定传输。
发明内容
本发明实施例的目的是提供一种用于文件同步的方法、接收方设备及系统，以解决上述现有技术中的问题。
为了实现上述目的，本发明实施例提供一种用于文件同步的方法，其中该方法包括：接收来自发送方设备的文件同步请求；基于请求发送响应消息至所述发送方设备，响应消息包括接收方设备的多个存储区域地址；接收发送方设备基于响应消息发送的多个文件块，多个文件块通过对待传输文件进行分块得到，并且多个文件块中的每个文件块包括唯一标识和与该唯一标识 对应的接收方设备的存储区域地址；以及根据每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址将每个文件块分配至对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到待传输文件。
本发明实施例还提供了一种用于文件同步的接收方设备，其中，该接收方设备包括：用于接收来自发送方设备的文件同步请求的装置；用于基于所述请求发送响应消息至所述发送方设备的装置，所述响应消息包括接收方设备的多个存储区域地址；用于接收所述发送方设备基于所述响应消息发送的多个文件块的装置，所述多个文件块通过对待传输文件进行分块得到，并且所述多个文件块中的每个文件块包括唯一标识和与该唯一标识对应的接收方设备的存储区域地址；以及用于根据每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址将每个文件块分配至对应的存储区域、并对存储在各个存储区域中的多个文件块进行实时组装以得到所述待传输文件的装置。
本发明实施例还提供了一种用于文件同步的方法，其中，该方法包括：发送方设备发送文件同步请求；接收方设备接收所述文件同步请求；所述接收方设备基于所述请求发送响应消息，所述响应消息包括接收方设备的多个存储区域地址；所述发送方设备基于所述响应消息发送多个文件块，所述多个文件块通过对待传输文件进行分块得到，并且所述多个文件块中的每个文件块包括唯一标识和与该唯一标识对应的接收方设备的存储区域地址；所述接收方设备接收所述多个文件块；以及所述接收方设备根据每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址将每个文件块分配至对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到所述待传输文件。
本发明实施例还提供了一种用于文件同步的系统，该系统包括发送方设 备和接收方设备，其中，所述发送方设备用于发送文件同步请求；所述接收方设备用于接收所述文件同步请求；所述接收方设备还用于基于所述请求发送响应消息，所述响应消息包括接收方设备的多个存储区域地址；所述发送方设备还用于基于所述响应消息发送多个文件块，所述多个文件块通过对待传输文件进行分块得到，并且所述多个文件块中的每个文件块包括唯一标识和与该唯一标识对应的接收方设备的存储区域地址；所述接收方设备还用于接收所述多个文件块；以及所述接收方设备还用于根据每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址将每个文件块分配至对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到所述待传输文件。
通过上述技术方案，可以接收发送方设备发送的通过对待传输文件进行分块得到的多个文件块，并利用每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址，将每个文件块分配至接收方设备对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到待传输文件。由此，可以实现待传输文件从发送方设备到接收方设备的同步过程。并且，由于待传输文件被分为多个文件块进行传输，所以避免了文件较大而出现传输错误的问题，实现了文件的稳定同步传输，提高了传输成功率。
本发明的其它特征和优点将在随后的具体实施方式部分予以详细说明。

所述接收方设备32还用于基于所述请求发送响应消息，所述响应消息包括接收方设备的多个存储区域地址；
所述发送方设备30还用于基于所述响应消息发送多个文件块，所述多个文件块通过对待传输文件进行分块得到，并且所述多个文件块中的每个文件块包括唯一标识和与该唯一标识对应的接收方设备的存储区域地址；
所述接收方设备32还用于接收所述多个文件块；以及
所述接收方设备32还用于根据每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址将每个文件块分配至对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到所述待传输文件。
通过接收方设备接收发送方设备发送的通过对待传输文件进行分块得到的多个文件块，并利用每个文件块的唯一标识和与该唯一标识对应的接收方设备的存储区域地址，将每个文件块分配至接收方设备对应的存储区域，并对存储在各个存储区域中的多个文件块进行实时组装，以得到待传输文件。由此，可以实现待传输文件从发送方设备到接收方设备的同步过程。并且，由于待传输文件被分为多个文件块进行传输，所以避免了文件较大而出现传输错误的问题，实现了文件的稳定同步传输，提高了传输成功率。
根据本发明一种实施方式，在该系统中：
所述发送方设备30还用于发送所述多个文件块各自的校验信息；
所述接收方设备32还用于接收所述多个文件块各自的校验信息；
所述接收方设备32还用于将所接收的所述多个文件块各自的校验信息分别与存储区域中对应的文件块所携带的校验信息进行比较；
所述接收方设备32还用于在比较结果为匹配的情况下发送表示文件块传输正确的响应；
所述接收方设备32还用于在比较结果为不匹配的情况下发送表示文件块传输错误的响应。
由此，接收方设备32可以通过校验信息对所接收的文件块的正确与否加以判断，并根据判断结果发送响应至发送方设备30，从而发送方设备30就可以获知所发送的文件块是否为正确的文件块。
此外，在发送的响应为表示文件块错误的响应的情况下，发送方设备30可以向接收方设备32重新发送正确的文件块以替换错误的文件块，以确保文件同步的正确性。
在本发明中，发送方设备30和接收方设备32可以均为客户端或服务器，也可以一者为客户端，而另一者为服务器。具体情况本领域技术人员可以根据实际情况进行设定，本发明不对此进行限定。
根据本发明一种实施方式，所发送的内容以及接收的内容可以被加密。
通过对所发送的内容以及接收的内容进行加密，可以确保同步传输过程中文件传输的安全性。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其 不违背本发明的思想，其同样应当视为本发明所公开的内容。
