Description

一种云盘资源访问方法和装置 技术领域
本申请涉及但不限于数据存储领域，尤其涉及一种云盘资源访问方法和装置。
背景技术
移动互联网的发展促使数据爆发增长，云存储提供海量的低成本存储资源，而目前个人云存储用户的规模正在不断扩大，包括很多企业的IT(Internet Technology，互联网技术)管理人员都在考虑将企业数据向云端迁移以降低运维成本。这些云存储服务针对非结构化数据大都提供基于HTTP(hyper text transfer protocol，超文本传输协议)的RESTful(Representational State Transfer)接口方式的对象操作接口。由于不同社交平台绑定自己的云盘应用，公有云盘单个账号申请的免费空间也有限制，因此很用户都同时拥有多个云盘账号。造成单个用户云端的空间资源分散，不能统一管理。同时也有一些企业用户不愿意绑定单个云存储服务提供商，希望从多个云存储服务提供商租用企业云盘，避免单个云存储系统出现故障宕机时数据不可用的情况。
通常云盘统一管理方案都是通过一个云端网盘文件管理器客户端，在云端网盘文件管理器客户端中登录多个账号，对每个云盘账号的空间分别切换管理，执行上传、下载、删除和检索云盘文件等操作。但是这种管理方案是不能跨云盘的执行的，不能真正实现多个云盘空间资源的整合利用和有效管理，每个云盘之间的数据可用性和QoS(Quality of Service，服务质量)无法保证。

本发明的实施方式
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
本发明实施例提供一种云盘资源访问方法。
参照图1，图1为本发明实施例云盘资源访问方法第一实施例的流程示意图。
在本实施例中，所述云盘资源访问方法包括步骤S10-S30：
步骤S10，获取云盘账号的访问令牌，根据所述访问令牌对应建立索引，以将所述云盘账号中的文件存储至云客户端中。
云客户端选择云盘提供的云盘账号，获取每个云盘账号的访问令牌。所述云客户端通过OAuth(Open Authorization)协议进行每个云盘账号用户的授权，获取每个用户云盘账号身份验证和授权的凭证，即获取每个用户云盘账号的访问令牌。所述云客户端将所述云盘账号添加至其虚拟的存储池中，根据其获取的访问令牌对应计算哈希值，根据所述哈希值对应建立索引，即将所述云盘账号中的文件虚拟存储至所述云客户端中虚拟的存储池中。所述索引所在的索引库维护存储池中所有文件的文件名称、文件大小、修改时间和版本号等属性，云客户端本地缓存路径，云端主文件和副本文件的所在位 置等字段。所述OAuth协议为用户资源的授权提供了一个安全的、开放而又简易的标准，用户对第三方应用一次授权后无需使用用户的用户名与密码就可以访问该用户授权的资源。
步骤S20，侦测用户对所述云盘账号中的文件的操作指令，获取与所述文件对应的索引。
所述云客户端侦测用户对所述云盘账号中的文件的操作指令，如侦测到用户要对某个云盘账号里的文件进行编辑、删除和备份等操作时，获取与所述文件对应的索引，所述文件的索引中的云客户端本地路径指向所述云客户端本地缓存的文件。对于所述云客户端应用的QoS、文件备份和安全加密的操作，所述云客户端提供本地缓存、云盘多副本和加密存储文件属性进行云盘存储管理。高QoS的应用对文件存储访问的延迟敏感，因此保留文件的本地缓存。对于容灾备份相关应用为防止系统故障或操作失误导致数据丢失，因此需要在多个云盘中存储副本进行备份。涉及安全性或用户隐私的敏感数据则需要在保存至云盘前对文件在线加密，转换为密文存储，密钥相关的数据在所述云客户端本地安全存放。
步骤S30，根据所述操作指令，通过所述索引在所述云客户端中对所述文件执行对应操作。
所述云客户端根据所述用户对所述云盘账号中的文件的操作指令，通过所述文件的索引查找到所述用户所要操作文件，在所述云客户端中对所述文件执行对应操作。如当所述云客户端的缓存区中的文件1具有QoS和备份的需求时，通过所述文件1的索引查找到所述文件1在所述缓存区中的位置。所述文件1的索引中的本地路径指向本地缓存区中文件1。所述云客户端将所述主文件1存储至与所述文件1的索引对应的哈希值的云盘账号中，文件1的副本文件可存储至存储空间相对较多的云盘中保存。如当所述云客户端需要对缓存区中的文件2进行在线加密后，再分发至某个云盘中时，如果所述缓存区中不存在所述文件2时，则需要到所述文件2所在的云盘中下载所述文件2到所述缓存区中进行解密处理。如所述云客户端还可以使文件3的索引存储于所述缓存区中，而所述文件3的主文件则存储于云盘中，以减少所述云客户端的硬盘资源的占用。
本实施例通过根据云盘账号的访问令牌对应建立索引，将云盘账号中文件存储至云客户端中，侦测对所述云盘账号中的文件的操作指令，获取与所述文件对应的索引，根据所述操作指令，通过所述索引在所述云客户端中对所述文件执行对应操作。实现了将多个云盘空间资源虚拟化在一个存储池中，实现了对多个云盘存储资源的统一调度管理，并根据不同的业务需求提供不同的存储服务。
参照图2，图2为本发明实施例中获取云盘账号的访问令牌，根据所述访问令牌对应建立索引，以将所述云盘账号中的文件存储至云客户端中的一种流程示意图。
在本实施例中，所述步骤S10包括步骤S11-S12：
步骤S11，根据获取的所述云盘账号的访问令牌对应扫描云盘账号中的文件。
步骤S12，根据所述云盘账号中的文件的属性对应建立全局索引，以将所述云盘账号中的文件存储至云客户端中。
当所述云客户端获取到每个云盘账号的访问令牌时，根据每个云盘账号的访问令牌对应扫描存储于不同云盘账号上的文件的元数据，依据每个云盘的文件的名称、位置、大小、类型等属性对应建立全局索引，以将所述每个云盘账号中文件虚拟存储至云客户端中虚拟的存储池中。
可选地，所述步骤S11中获取云盘账号的访问令牌包括步骤S111-S113：
S111、通过预置接口向所述云盘账号所在云盘发送验证码请求，令所述云盘根据所述验证码请求返回验证码和授权页面的统一资源定位符URL。
所述云客户端注册每个云盘账号的开放接口的应用API(Application Programming Interface，应用程序编程接口)key。所述云客户端从所述云盘账号所在云盘中选择要添加至所述存储池中的云盘账号，并通过预置接口向每个云盘发送验证码请求，当所述云盘接收到所述验证码请求时，所述云盘验证所述云客户端的身份，当所述云盘验证所述云客户端的身份后，根据所述验证码请求发送所述云盘账号的验证码和授权页面的URL(Uniform Resource Locator，统一资源定位符)给所述云客户端。所述预置接口即为每个云盘的 开放接口的应用API key。即所述云客户端从云盘中选择要添加至所述存储池中的云盘账号，通过所述云盘的开放接口的应用API key向所述云盘发送验证码请求。
S112、当接收到所述验证码和所述授权页面的URL时，输出提示消息，提示用户在所述授权页面上对应输入所述云盘账号的账号和密码。
S113、当侦测到所述用户在授权页面上输入的账号和密码时，根据所述验证码对应获取所述云盘账号的访问令牌。
当所述云客户端接收到所述云盘账号的验证码和所述授权页面的URL时，输出提示消息，提示用户在所述授权页面上对应输入所述云盘账号的账号和密码。在用户在所述授权页面上对应输入所述云盘账号的账号和密码的过程中，所述云客户端将所述验证码和其回调连接发送给所述云盘。当所述云客户端侦测到所述用户在所述授权页面上输入的账号和密码时，所述云盘授权所述云客户端访问所述云盘账号中文件的资源。当授权成功后，所述云盘引导所述用户从所述授权页面上返回至所述云客户端的页面。当返回到所述云客户端的页面时，所述云客户端根据所述验证码对应从所述云盘中获取所述云盘账号的访问令牌。所述云盘根据所述验证码和对所述用户的授权情况授予所述云客户端的访问令牌。
可选地，所述方法还包括：当侦测到所述用户在授权页面上输入的账号和密码时，在根据所述验证码对应获取所述云盘账号的访问令牌之后，根据所述访问令牌计算哈希值。
建立所述云盘账号、所述访问令牌和所述哈希值的对应关系表。
将所述对应关系表同步到对应的云盘账号中，其中，所述对应关系用于当更换云客户端时，从所述云盘账号中获取所述对应关系表，根据所述对应关系表对应建立索引。
所述云客户端根据所述访问令牌计算哈希值，建立所述云盘账号、所述访问令牌和所述哈希值的对应关系表，并将所述对应关系表在所述云客户端本地加密保存。所述对应关系表为token表。当所述云客户端在其存储池中完成了添加云盘账号的操作时，使用和所述云盘账号对应的访问令牌将所述 token表同步到对应的云盘中进行安全备份。当需要更换客户端时，在新的云客户端完成在各个云盘的登录认证之后，反向同步从云端获取所述token表，不需要重新对每个云盘账号进行用户的授权认证，直接使用所述token表中的访问令牌扫描对应的云盘建立对应的云盘账号文件的全局索引。
本实施例通过建立每个云盘账号、所述访问令牌和所述哈希值的对应关系表，将所述对应关系表同步到对应的云盘账号中，以供当更换云客户端时，可以从所述云盘账号中获取所述对应关系表，根据所述对应关系表对应建立索引。使所述云客户端支持异地重建，解决了云客户端环境迁移问题。
参照图3，图3为本发明实施例中根据所述操作指令，通过所述索引在所述云客户端中对所述文件执行对应操作的一种流程示意图。
在本实施例中，所述步骤S30包括步骤S31-S33：
步骤S31，当所述操作指令是要对所述文件执行编辑操作时，判断所述文件对应的索引所在的缓存区中是否存在所述文件。
所述云客户端侦测到用户的操作指令是要对云盘账号中的文件执行编辑操作时，如需要在所述云盘账号中新增文件时，所述云客户端的应用使用其统一文件访问接口新增文件，指定所述新增文件的名称和业务属性。当所述云客户端在指定所述新增文件的名称和业务属性后，创建所述新增文件的索引，并在所述云客户端的缓存区中编辑所述新增文件的内容，通过HTTP接口上传所述新增文件，更新所述云客户端的本地文件索引。所述云盘账号使用一致性的哈希算法，即所述云客户端将所述云盘账号和所述云盘账号中的文件数据映射到同一个线性地址空间，每一个云盘账号负责保存前一个云盘账号到本云盘账号之间的数据。当所述云客户端需要编辑文件时，首先通过所述需要编辑的文件的索引判断所述索引所在的缓存区中是否存在所述需要编辑的文件。可选地，所述统一文件访问接口可以扩充为面向本地网络的文件访问接口，不仅使本地的云客户端中的应用可以调用所述统一文件访问接口，同时也满足多个终端通过其云客户端访问存储池中的云盘资源。
步骤S32，如果所述缓存区中不存在所述文件，则通过向存储所述文件的云盘账号发送下载请求下载所述文件，并将下载的所述文件保存至所述缓存区中；
当所述云客户端判定所述缓存区中不存在所述需要编辑的文件时，则向存储所述需要编辑的文件的云盘账号发送下载所述需要编辑的文件的请求，当所述云盘账号接收到所述下载所述需要编辑的文件的请求时，所述云客户端就可以从所述云盘账号中下载所述需要编辑的文件，并将下载的所述需要编辑的文件保存至所述缓存区中。
步骤S33，如果所述缓存区中存在所述文件，则在所述缓存区中对所述文件执行对应的编辑操作。
当所述云客户端判定所述缓存区存在所述需要编辑的文件时，则将所述缓存区中所述需要编辑的文件与所述云盘账号中的对应的文件进行对比，当发现所述缓存区中所述需要编辑的文件的版本低于所述云盘账号中对应的文件的版本时，从所述云盘账号中下载与所述需要编辑的文件对应的文件，替换所述缓存区中的所述需要编辑的文件，并在所述缓存区中对所述需要编辑的文件执行对应的编辑操作。当所述云客户端完成对所述需要编辑的文件的编辑操作时，通过云盘更新接口将所述编辑后的文件上传至所述云盘中。因为在所述云客户端本地的缓存区中缓存的云盘账号的文件，所以在所述用户离线时，所述用户也可以在所述云客户端中进行云盘账号文件的编辑操作，得到新版本的文件，等到所述云盘账号在线时，在将所述新版本的文件同步到对应的云盘账号中。由于某些云盘的存储服务为开发者提供的结构化数据操作和管理的功能，开发者可以将数据的属性抽象出来，基于结构化数据API创建数据表，并对数据表里的记录执行增加、删除、修改和查询等管理操作。所述云客户端可以为云盘存储的文件建立索引数据表，扫描建立的索引时可从各个云盘索引数据表中获取索引信息，从而加快索引的建立效率。
本实施例通过对分散的多个云盘存储资源的全局地址空间统一管理，并实现不同特性的应用存储服务，解决了云盘资源的整合问题。

所述云客户端注册每个云盘账号的开放接口的应用API(Application Programming Interface，应用程序编程接口)key。所述云客户端从所述云盘账号所在云盘中选择要添加至所述存储池中的云盘账号，并通过预置接口向每个云盘发送验证码请求，当所述云盘接收到所述验证码请求时，所述云盘验证所述云客户端的身份，当所述云盘验证所述云客户端的身份后，根据所述验证码请求发送所述云盘账号的验证码和授权页面的URL(Uniform Resource Locator，统一资源定位符)给所述云客户端。所述预置接口即为各个云盘的开放接口的应用API key。即所述云客户端从云盘中选择要添加至所述存储池中的云盘账号，通过所述云盘的开放接口的应用API key向所述云盘发送验证码请求。
输出单元，设置为当接收到所述验证码和所述授权页面的URL时，输出提示消息，提示用户在所述授权页面上对应输入所述云盘账号的账号和密码。
获取单元，设置为当侦测到所述用户在授权页面上输入的账号和密码时，根据所述验证码对应获取所述云盘账号的访问令牌。
当所述云客户端接收到所述云盘账号的验证码和所述授权页面的URL时，输出提示消息，提示用户在所述授权页面上对应输入所述云盘账号的账号和密码。在用户在所述授权页面上对应输入所述云盘账号的账号和密码的过程中，所述云客户端将所述验证码和其回调连接发送给所述云盘。当所述云客户端侦测到所述用户在所述授权页面上输入的账号和密码时，所述云盘授权所述云客户端访问所述云盘账号中文件的资源。当授权成功后，所述云盘引导所述用户从所述授权页面上返回至所述云客户端的页面。当返回到所述云客户端的页面时，所述云客户端根据所述验证码对应从所述云盘中获取所述云盘账号的访问令牌。所述云盘根据所述验证码和对所述用户的授权情况授予所述云客户端的访问令牌。
可选地，所述建立模块10还包括：计算单元、第二建立单元和同步单元。
计算单元，设置为当侦测到所述用户在授权页面上输入的账号和密码时，在所述获取单元根据所述验证码对应获取所述云盘账号的访问令牌之后，根据所述访问令牌计算哈希值。
第二建立单元，设置为建立所述云盘账号、所述访问令牌和所述哈希值的对应关系表。
同步单元，设置为将所述对应关系表同步到对应的云盘账号中，其中，所述对应关系用于当更换客户端时，从所述云盘账号中获取所述对应关系表，根据所述对应关系表对应建立索引。
所述云客户端根据所述访问令牌计算哈希值，建立所述云盘账号、所述访问令牌和所述哈希值的对应关系表，并将所述对应关系表在所述云客户端本地加密保存。所述对应关系表为token表。当所述云客户端在其存储池中完成了添加云盘账号的操作时，使用和所述云盘账号对应的访问令牌将所述token表同步到对应的云盘中进行安全备份。当需要更换客户端时，在新的云客户端完成在各个云盘的登录认证之后，反向同步从云端获取所述token表，不需要重新对每个云盘账号进行用户的授权认证，直接使用所述token表中的访问令牌扫描对应的云盘建立对应的云盘账号文件的全局索引。
本实施例通过建立各个云盘账号、所述访问令牌和所述哈希值的对应关系表，将所述对应关系表同步到对应的云盘账号中，以供当更换云客户端时，可以从所述云盘账号中获取所述对应关系表，根据所述对应关系表对应建立索引。使所述云客户端支持异地重建，解决了云客户端环境迁移问题。
参照图6，图6为本发明实施例中执行模块的一种功能模块示意图。
在本实施例中，所述执行模块30包括：判断单元31、第二发送单元32和执行单元33。
所述执行模块根据所述操作指令，通过所述索引在所述云客户端中对所述文件执行对应操作包括：
判断单元31，设置为当所述操作指令是要对所述文件执行编辑操作时，判断所述文件对应的索引所在的缓存区中是否存在所述文件。
所述云客户端侦测到用户的操作指令是要对云盘账号中的文件执行编辑 操作时，如需要在所述云盘账号中新增文件时，所述云客户端的应用使用其统一文件访问接口新增文件，指定所述新增文件的名称和业务属性。当所述云客户端在指定所述新增文件的名称和业务属性后，创建所述新增文件的索引，并在所述云客户端的缓存区中编辑所述新增文件的内容，通过HTTP接口上传所述新增文件，更新所述云客户端的本地文件索引。所述云盘账号使用一致性的哈希算法，即所述云客户端将所述云盘账号和所述云盘账号中的文件数据映射到同一个线性地址空间，每一个云盘账号负责保存前一个云盘账号到本云盘账号之间的数据。当所述云客户端需要编辑文件时，首先通过所述需要编辑的文件的索引判断所述索引所在的缓存区中是否存在所述需要编辑的文件。可选地，所述统一文件访问接口可以扩充为面向本地网络的文件访问接口，不仅使本地的云客户端中的应用可以调用所述统一文件访问接口，同时也满足多个终端通过其云客户端访问存储池中的云盘资源。
第二发送单元32，设置为如果所述缓存区中不存在所述文件，则通过向存储所述文件的云盘账号发送下载请求下载所述文件，并将下载的所述文件保存至所述缓存区中。
当所述云客户端判定所述缓存区中不存在所述需要编辑的文件时，则向存储所述需要编辑的文件的云盘账号发送下载所述需要编辑的文件的请求，当所述云盘账号接收到所述下载所述需要编辑的文件的请求时，所述云客户端就可以从所述云盘账号中下载所述需要编辑的文件，并将下载的所述需要编辑的文件保存至所述缓存区中。
执行单元33，设置为如果所述缓存区中存在所述文件，则在所述缓存区中对所述文件执行对应的编辑操作。
当所述云客户端判定所述缓存区存在所述需要编辑的文件时，则将所述缓存区中所述需要编辑的文件与所述云盘账号中的对应的文件进行对比，当发现所述缓存区中所述需要编辑的文件的版本低于所述云盘账号中对应的文件的版本时，从所述云盘账号中下载与所述需要编辑的文件对应的文件，替换所述缓存区中的所述需要编辑的文件，并在所述缓存区中对所述需要编辑的文件执行对应的编辑操作。当所述云客户端完成对所述需要编辑的文件的编辑操作时，通过云盘更新接口将所述编辑后的文件上传至所述云盘中。因 为在所述云客户端本地的缓存区中缓存的云盘账号的文件，所以在所述用户离线时，所述用户也可以在所述云客户端中进行云盘账号文件的编辑操作，得到新版本的文件，等到所述云盘账号在线时，在将所述新版本的文件同步到对应的云盘账号中。由于某些云盘的存储服务为开发者提供的结构化数据操作和管理的功能，开发者可以将数据的属性抽象出来，基于结构化数据API创建数据表，并对数据表里的记录执行增加、删除、修改和查询等管理操作。所述云客户端可以为云盘存储的文件建立索引数据表，扫描建立的索引时可从各个云盘索引数据表中获取索引信息，从而加快索引的建立效率。
本实施例通过对分散的多个云盘存储资源的全局地址空间统一管理，并实现不同特性的应用存储服务，解决了云盘资源的整合问题。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现所述的云盘资源访问方法。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括多个指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明实施例所述的方法。
以上仅为本发明可选实施例，并非因此限制本发明实施例的专利范围，凡是利用本发明实施例说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明实施例的专 利保护范围内。
