在一个实施例中，还包括：
所述管理设备，配置为当所述目标数据在所述存储设备中移除时，回收所述第二验证信息，并分别删除所述接入设备和所述存储设备中的所述第二验证信息。
在本申请实施例中，接入设备在获取到用户终端发送的携带有目标数据的数据信息的数据请求时，可以获取到与数据信息关联的存储设备标识，同时还可以获取与数据信息关联的预先设置的第一验证信息，通过接入设备将第一验证信息和数据信息发送至存储设备标识对应的存储设备，以供存储设备验证第一验证信息，并在验证通过后将数据信息指示的目标数据返回至接入设备，最终由接入设备将目标数据发送至用户终端以响应数据请求。通过加入与所请求数据的数据信息相关联的第一验证信息，并在第一验证信息通过后才可以获取请求的数据，避免由于数据转移或其它新的数据代替时导致的获取到错误数据的情况，保证了所请求数据的准确性以及安全性；通过预先对目标数据分配唯一的第二验证信息，可以在后续数据请求时，对第一验证信息和第二验证信息进行匹配，进一步实现了对数据获取的过程，有效的保证了所请求数据的准确性以及安全性；通过对利用后的第二验证信息进行回收，可以实现验证信息的重复利用，优化了分布式系统中的资源分配，提高了分布式系统的可用性。
如图15所示，本实施例提供一种数据请求处理方法，应用于接入设备中，包括：
步骤S710：接收用户终端发送的携带第一标识的数据请求；其中，所述数据请求为：存储目标数据的存储请求或读取目标数据的读取请求，所述第一标识为所述用户客户端按照预设规则生成的，与所述目标数据存储相关的标识；
步骤S720：对所述第一标识进行预设处理，以获得第一存储设备标识，其中，所述第一存储设备标识为：存储所述目标数据的存储设备的设备标识；
步骤S730：获取对所述接入设备进行存储验证的第一验证信息；
步骤S740：根据所述第一存储设备标识，向对应的存储设备发送所述数据请求及所述第一验证信息，其中，所述第一验证信息，用于对应的存储设备对所述接入设备进行存储验证，所述数据请求，用于触发对应的存储设备在通过所述存储验证后进行数据请求响应；
步骤S750：接收对应的存储设备返回的所述数据请求的处理结果；
步骤S760：根据所述处理结果向所述用户终端返回所述数据请求的响应结果。
本发明实施例提供的接入设备的为可供用户终端接入到存储设备所在网络的设备。
通常情况下，根据就近存储原址，所述接入设备对应的存储设备可为在物理空间上或在拓扑空间上，与所述接入设备比较相近的存储设备。
在本实施例中接入设备与所述用户终端可建立数据连接。所述用户终端可以根据自身的需求，向接入设备发送数据请求。这里的数据请求包括：请求存储数据的存储请求，和请求读取数据的读取请求。在本实施例中待存储的数据或待读取的数据都为本次数据请求指向的目标数据。
用户终端在请求存储数据之前，会基于预设规则生成一个标识该目标数据存储的标识，该标识在本实施例中称之为第一标识，可作为后续用户 终端查询或操作该目标数据的标识。不管是存储请求还是读取请求中，都会携带所述第一标识。在一些情况下，所述第一标识可称为操作所述目标数据的键值(key)。
接入设备在接收到携带有第一标识的数据请求之后。
在步骤S420中会对所述第一标识进行预设处理，例如，对所述第一标识进行函数处理，这里的函数可为哈希函数，则对所述第一标识进行哈希处理。在步骤S720中可采用MD5算法对所述第一标识进行哈希处理，处理得到的函数值，与存储设备的存储设备标识具有对应关系，例如，函数值本身就可以直接作为所述存储设备标识，或基于函数值与存储设备标识的对应关系，获得一个存储设备标识。在本实施例中通过对第一标识的处理，得到的存储设备标识为第一存储设备标识。这里的第一存储设备标识，可为存储所述目标数据或存储有所述目标数据的存储设备的设备标识。所述设备标识可为国际设备标识(IMEI)、或网络协议(IP)地址，或者，管理设备分配的存储逻辑地址等标识设备的序列和/或字符串等信息。
接入设备在确定出响应所述数据请求的存储设备的第一存储设备标识以后，需要向对应的存储设备发送所述数据请求。在本实施例中，还会同步发送对所述接入设备进行存储验证的第一验证信息。
该第一验证信息是专门针对于所述接入设备的验证信息。在本实施例中，不管所述接入设备接收的数据请求是来自哪一个用户终端，例如，来自用户终端A和用户终端B，若所述接入设备自身对应的验证信息未变，则针对于用户终端A和用户终端B的数据请求，向存储设备发送的是同一个第一验证信息。
这样的话，第一存储设备标识对应的存储设备，接收到的不仅有数据请求，还有针对于接入设备的第一验证信息。
存储设备在进行数据请求的响应之前，首先对第一验证信息进行验证。 若接入设备当前异常，则可能无法提供正确的第一验证信息，则可能会导致存储验证失败，若存储验证失败，则存储设备会拒绝响应所述数据请求，从而不管是存储数据，还是读取数据，都可以避免因为接入设备异常导致的数据处理错误、数据错误读取导致的泄露等问题。
在本实施例中第一验证信息是针对于接入设备的，而非针对所述目标数据或所述数据请求的，这样的话，通过一个接入设备进行的数据请求响应，可能仅需要一个第一验证信息，显然验证信息的条数少，不用单独为每一个目标数据或数据请求分配对应的验证信息进行存储验证。
且在本实施例中，所述第一验证信息是针对于接入设备的，若接入设备发送给了错误的存储设备，则有可能第一验证信息无法通过验证，从而可以接入设备处理异常导致的错误写入，例如，错误写入了接入设备未有权限写入的存储设备中，导致对应的存储设备在响应其写入操作覆盖了其他接入设备写入的数据的问题，提升了数据存储的可靠性和鲁棒性。
在本实施例中，不管是数据存储还是数据读取，都需要结合第一验证信息进行验证。
在步骤S730中获取所述第一验证信息，可包括：在所述接入设备的本地查询所述第一验证信息，或者，接入设备按照预设方式基于一定生成参数生成所述第一验证信息。存储设备在进行第一验证信息的验证时，同样可以采用同样的方式生成一个验证信息，用于对所述接入设备的存储验证。
存储设备会对所述数据请求进行相应的处理，形成一个处理结果。
在本实施例中所述处理结果包括：第一类处理结果及第二类处理结果。
所述第一类处理结果，用于指示根据存储验证是否通过，指示是否响应所述数据请求。所述第一类处理结果，至少包括：验证失败。
所述第二类处理结果，用于指示在存储验证通过后，对所述目标数据的处理结果。所述第二类处理结果包括：响应存储请求的存储成功或存储 失败的处理结果。所述第二类存储结果还包括：响应读取请求成功时返回的包括目标数据的处理结果，响应读取请求未成功读取到目标数据时的处理结果。
所述步骤S750可包括：所述接入设备接收到所述第二类处理结果之后，可以直接将第二类结果作为所述数据请求的最终响应结果，返回给所述用户终端。
所述步骤S750可包括：所述接入设备接收到第一类处理结果之后，所述接入设备可以重新执行所述步骤S720至步骤S750，一直到从所述存储设备接收到所述第二类处理结果，或者，重复执行所述步骤S720至步骤S750预定次数，达到预定次数之后第一验证信息仍然没有通过验证，则直接向所述用户终端返回响应失败的结果。当然以上尽是举例，在一些情况下，所述接入设备可以直接将所述处理结果转发给所述用户终端。
当所述数据请求为存储请求时，在步骤S740中接入设备会将待存储的目标数据发送给存储设备，供存储设备存储。
当所述数据请求为读取请求时，在步骤S740中携带的数据请求中是没有对应的目标数据，若存储设备查询到了对应的目标数据，则会在步骤S750中接入设备会接收到携带有目标数据的处理结果。
在一些实施例中，所述第一验证信息包括：管理设备下发给所述接入设备的第一路由信息，其中，所述第一路由信息为：所述管理设备根据分配给所述接入设备的存储区域生成的信息。
所述第一路由信息可包括：分配给所述接入设备的存储区域的起始子区域的存储地址，和/或，所述存储区域的终止子区域的存储地址等生成的。
所述第一路由信息可以直接为所述起始子区域的存储地址和终止子区域的存储地址，也可以是采用哈希算法等各种函数，对所述存储地址等进行处理之后生成的信息，还可以是分配给所述接入设备的整个存储区域的 存储地址等。
在本实施例中所述第一路由信息，不仅可以告知接入设备，当前管理设备分配给其存储区域的相关信息，还被复用作为所述第一验证信息使用。这样的话，管理设备可以不用额外下发信息就相当于向接入设备告知了第一验证信息，一方面实现了信息复用，另一方面不需要额外的增加信息交互的信令开销，与现有技术的兼容性强。
可选地，所述方法还包括：
根据所述第一路由信息，判断对所述第一存储设备标识是否为预设存储设备标识；其中，所述预设存储设备标识为分配给所述接入设备进行数据存储的存储设备的设备标识；
所述步骤S740可包括：当所述第一存储设备标识为所述预设存储设备标识时，向所述第一存储设备标识对应的存储设备发送所述数据请求及所述第一验证信息。
例如，通过对第一标识的处理，得到的第一存储设备标识，明显并非位于所述第一路由信息对应的存储区域中，表明接入设备没有对该数据的操作权限或接入设备在计算所述第一存储设备标识的过程中出现了错误，或者，接入设备及用户终端的至少其中之一出现故障，则此时可以不用向存储设备发送所述数据请求，以减少所述存储设备的数据请求的无效负载。
在一些实施例中，所述方法还包括：
接收管理设备下发的针对所述接入设备的第一存储配置信息，其中，所述第一存储配置信息至少包括：所述第一验证信息或所述第一验证信息的生成信息。
其中，所述第一存储配置信息，包括所述第一验证信息，或所述第一验证信息的生成信息。这里的生成信息可包括：生成策略及生成参数；利用所述生成策略对所述生成参数进行数据处理，会得到所述第一验证信息。 所述第一存储配置信息也可以直接携带所述第一验证信息。例如，当所述第一验证信息为所述第一路由信息时，所述第一存储配置信息可以直接包括所述第一路由信息即可。
如图16所示，本实施例提供一种数据请求处理方法，应用于存储设备中，包括：
步骤S810：从接入设备接收用户终端的数据请求及所述接入设备对应的第一验证信息；
步骤S820：基于所述第一验证信息对所述接入设备进行存储验证；
步骤S830：当基于所述第一验证信息通过所述存储验证时，响应所述数据请求，以获得处理结果；
步骤S840：将所述处理结果返回给所述接入设备。
本实施例提供的数据请求处理方法，为应用于存储设备中的方法。存储设备从接入设备接收的数据请求的同时，还会接收针对于接入设备的第一验证信息。
在响应所述数据请求之前，需要先基于第一验证信息对接入设备进行存储验证。若存储验证通过之后，才会响应所述数据请求，这样的话，相当于只有确定出接入设备自身正常的情况下，才会进行所述数据请求的响应，至少解决了接入设备的异常导致的存储异常和读取异常的问题。
可选地，所述方法还包括：
从管理设备接收针对于所述接入设备的第二存储配置信息；
基于所述第二存储配置信息，获得第二验证信息；
所述步骤S820可包括：将所述第一验证信息和所述第二验证信息进行匹配；当所述第一验证信息和所述第二验证信息一致时，确定所述存储验证通过。
所述存储设备预先从管理设备针对于接入设备的第二存储配置信息。 基于第二存储配置信息，获得第二验证信息，可包括：从第二存储配置信息中直接提取所述第二验证信息。或者，根据所述第二存储配置信息生成所述第二验证信息。例如，根据第二存储配置信息生成第二验证信息时，可以基于生成参数及生成规则进行生成处理，得到所述第二存储配置信息。这里存储设备接收的生成参数和生成规则，和接入设备从管理设备接收的生成参数和生成规则是一致。
在步骤S820中，匹配第一验证信息和第二验证信息。若两个验证信息匹配已知，则存储验证通过，否则可认为存储验证不同。
在一些实施例中，所述基于所述第二存储配置信息，获得第二验证信息可包括：基于所述第二存储配置信息，获得所述接入设备对应的第二路由信息，其中，所述第二路由信息为所述存储设备根据管理设备分配给所述接入设备的存储区域生成的。
若接入设备提供的第一验证信息为第一路由信息，则在所述步骤S820可包括：将第一路由信息和第二路由信息进行匹配，根据匹配的结果，进行存储验证。
当所述数据请求为存储请求时，所述步骤S830可包括：
在基于第一验证信息通过所述存储验证时，存储所述目标数据；
并形成目标数据的存储记录，该存储记录包括所述目标数据的存储位置及所述第一标识的对应关系，这样后续，若用户终端查询所述目标数据时，接收到携带有第一标识的读取请求之后，可以依据第一标识查询所述存储记录，基于存储记录中的对应关系，到对应的存储位置读取所述目标数据，将所述目标数据返回给所述接入设备。
故当所述数据请求为读取请求时，所述步骤S830可包括：
当基于所述第一验证信息通过存储验证时，从所述读取请求中提取第一标识；
以所述第一标识为查询依据查询所述对应关系，确定出所述目标数据的存储位置；
到所述存储位置读取所述目标数据。
