实施例一
本申请实施例给出一种资源下载方法，请参考图1，其为本申请实施例所提供的资源下载方法的实施例一的流程示意图，如图1所示，该方法包括以下步骤：
S101，缓存设备获取用户设备发送的资源请求，该资源请求中包含所请求的资源标识。
本申请实施例中，用户设备发送资源请求，是为了向提供所请求的资源的服务器获取所请求的资源服务。用户设备所请求的资源可以包括但不限于：视频文件资源、音频文件资源、图像文件资源、 文档文件资源和应用文件资源中的至少一个。
具体的，本申请实施例中，缓存设备获取用户设备发送的资源请求的实现方法可以包括但不限于以下两种：
第一种：用户设备向提供所请求的资源的服务器发送资源请求，缓存设备获取用户设备向该服务器的资源请求。具体的，例如：镜像报文分析、域名劫持重定向等手段。
以用户设备向S网站请求视频资源A为例进行说明，此时，S网站即为提供所请求的资源的服务器。例如：用户设备可以直接向S网站发送请求视频资源A的资源请求，而并不额外的向缓存设备发送资源请求，此时，缓存设备获取用户设备发送的资源请求，可以通过对用户设备发送给S网站的资源请求进行镜像报文分析实现，通过镜像报文分析后，用户设备发送的资源请求发送给S网站，而缓存设备也可以获取到用户设备发送的资源请求。或者，又例如：用户设备可以直接向S网站发送请求视频资源A的资源请求，而并不额外的向缓存设备发送资源请求，此时，缓存设备接收用户设备发送的资源请求，可以通过对用户设备发送给S网站的资源请求进行域名劫持重定向，将用户设备发送给S网站的资源请求重定向给缓存设备，通过域名劫持重定向后，用户设备发送的资源请求会重定向给缓存设备，缓存设备就可以接收到用户设备发送的资源请求，而S网站不能接收到用户设备发送的资源请求。
第二种：用户设备向提供所请求的资源的服务器发送资源请求时，同时向缓存设备发送该资源请求，缓存设备接收用户设备发送的资源请求。
以用户设备向S网站请求视频资源A为例进行说明，此时，S网站即为提供所请求的资源的服务器。例如：用户设备向S网站和缓存设备，同时发送请求视频资源A的资源请求，因此，缓存设备能够接收到用户设备发送的资源请求。或者，又例如：用户设备向S网站发送该视频文件的资源请求时，同时复制一份该资源请求，向缓存设备发送该复制后得到的资源请求，因此，缓存设备即可接 收到用户设备发送的资源请求。
本申请实施例中，缓存设备获取到的用户设备发送来的资源请求中，包括所请求的资源标识，是为了使缓存设备能够根据该资源标识，查找自身存储的资源中是否有用户设备所请求的资源，以及当缓存设备确定自身存储有用户设备所请求的资源时，根据该资源标识确定用户所请求的资源类别。
具体的，本申请实施例中的资源标识可以包括但不限于：用户请求的资源的统一资源定位符(Uniform Resource Locator，URL)和用户请求的资源的文件名中的至少一个。
S102，缓存设备根据资源标识，确定所请求的资源类别。
本申请实施例中，基于需要存储的资源的类别不同，缓存设备可以按照分类存储的方式存储各类别的资源，并建立不同类别的资源列表。
例如，缓存设备可以按照资源的权限类别对自身存储的资源进行分类存储，若将自身存储的资源分类为：权限类资源与非权限类资源，则缓存设备可以分别建立用于存储权限类资源的权限资源列表，和用于存储非权限类资源的非权限类资源列表。因此，缓存设备每次新存储资源时，都会按照上述的分类列表进行分类存储。
需要说明的是，本申请实施例中，每一个资源一定有一个用以表明该资源是否为权限类资源的资源标识，本申请实施例对资源的其他资源标识的种类和数目不进行特别限定。在一个具体的实现过程中，若缓存设备按照其他的类别方式对资源进行分类存储时，缓存设备可以将是否为权限类资源作为资源的一个资源标识，该资源标识与用户设备发送的资源请求中携带的资源标识是一致的。
例如，缓存设备可以按照资源的数据格式进行分类，将自身存储的资源分为：视频类资源、音频类资源、文本类资源和应用类资源，并建立相应的列表进行分类存储资源。而针对缓存设备中存储的某一视频资源A，视频资源A为权限类资源，则缓存设备将该视频资源A存储在视频类资源的分类列表下，同时为视频资源A添加 权限类资源的资源标识；而针对缓存设备中存储的某一文本资源B，文本资源B为非权限类资源，则缓存设备将该文本资源B存储在文本类资源的分类列表下，同时为文本资源B添加非权限类资源的资源标识。
需要说明的是，本申请实施例中，对于对资源进行分类的执行主体不进行特别限定。例如，在一个具体的实现过程中，缓存设备可以预先对资源进行分类，并为不同类别的资源添加相应的资源标识，然后缓存设备可以根据该资源标识对自身存储的资源进行分类存储。或者，又例如，在另一个具体的实现过程中，管理服务器可以对资源进行分类，并为不同类别的资源添加相应的资源标识，缓存设备只需要按照管理服务器为资源添加的资源标识进行分类存储即可。
可以理解的是，本申请实施例中，对于对资源进行分类并添加资源标识时，确定所存储的资源是否为权限类资源可以有多种实现方式。举例说明，可以将一些需要会员等验证的资源划分为权限类资源，和/或，还可以将一些付费网站提供的资源，如付费电影等，划分为权限类资源；可以将一些不需要会员等验证的资源划分为非权限类资源，如开源的软件、软件升级补丁等，和/或，还可以将一些不需要付费的网站提供的资源划分为非权限类资源。本申请实施例上述举例仅仅是确定所存储的资源是否为权限类资源的几种具体的实现方式，通过其他的实现方式也能达到该目的，本申请对此不进行限定。
本申请实施例中，缓存设备接收到用户设备发送的资源请求后，即可根据资源请求中的资源标识，确定用户设备所请求的资源的资源类别。
举例说明，缓存设备根据资源标识，获取请求的资源类别的实现方法可以包括但不限于：缓存设备根据资源标识，判断自身是否存储有与资源标识对应的资源；若缓存设备存储有与资源标识对应的资源，缓存设备根据存储的各资源的类别以及资源标识，获取请 求的资源类别。该方法仅为举例说明，本申请实施例中，缓存设备根据资源标识，确定所请求的资源类别的具体方式，本申请实施例不进行限定。
在一个具体的实现过程中，缓存设备可以将获取到的用户所请求的资源的资源标识，与缓存设备所存储的分类列表中各资源标识进行一一比对，确定缓存设备自身存储的资源中是否存在用户设备所请求的资源，若缓存设备中自身存储的资源中存在用户设备所请求的资源，进而可以确定用户设备所请求的资源的资源类别。本申请实施例中，先确定缓存设备自身存储的资源中是否存在用户设备所请求的资源，再去确定用户设备所请求的资源的资源类别，避免了先确定所请求的资源类别，再确定自身存储中是否存在用户设备所请求的资源，带来的大量的无效工作，节省了缓存设备的工作量，提升了缓存设备的操作效率。
例如，若用户所请求的资源是S网站所提供的视频资源A，视频资源A是S网站的付费视频，缓存设备将视频资源A存储在权限类资源列表下，若资源标识为URL，权限类资源的资源标识的URL为www.a.com。当缓存设备接收到用户设备发送的请求视频资源A的资源请求后，通过一一比对自身存储的各资源列表，确定视频资源A是否存在，若存在，进而根据资源请求中携带的URL为www.a.com的资源标识，确定视频资源A为权限类资源。
或者，又例如，若用户所请求的资源是S网站所提供的视频资源B，视频资源B是S网站的免费视频，缓存设备将视频资源B存储在非权限类资源列表下，若资源标识为URL，权限类资源的资源标识的URL为www.b.com。当缓存设备接收到用户设备发送的请求视频资源B的资源请求后，通过一一比对自身存储的各资源列表，确定视频资源B是否存在，若存在，进而根据资源请求中携带的URL为www.b.com的资源标识，确定视频资源B为非权限类资源。
或者，又例如，用户所请求的资源是S网站所提供的视频资源A，视频资源A是S网站的付费视频，缓存设备将视频资源A存储 在权限类资源列表下，若权限类资源的资源标识为资源文件名的最后三位为“abc”。当缓存设备接收到用户设备发送请求视频资源A的的资源请求后，通过一一比对自身存储的各资源列表，确定视频资源A是否存在，若存在，进而根据资源请求中携带的所请求的资源的文件名的最后三位为“abc”的资源标识，确定视频资源A为权限类资源。
或者，又例如，用户所请求的资源是S网站所提供的视频资源B，视频资源B是S网站的免费视频，缓存设备将视频资源B存储在非权限类资源列表下，若权限类资源的资源标识为资源文件名的最后三位为“bcd”。当缓存设备接收到用户设备发送请求视频资源B的的资源请求后，通过一一比对自身存储的各资源列表，确定视频资源B是否存在，若存在，进而根据资源请求中携带的所请求的资源的文件名的最后三位为“bcd”的资源标识，确定视频资源B为非权限类资源。
具体的，本申请实施例中，若缓存设备中没有用户设备所请求的资源，缓存设备本次不为用户设备提供任何服务，而且，缓存设备可以从提供该资源的服务器获取一份用户设备所请求的资源，并进行分类存储，以便于向此后请求该资源的用户设备提供该资源。此时，用户设备不能通过缓存设备得到所请求的资源，但可以通过其他方式获取到所请求的资源，例如，通过提供所请求的资源的服务器。
S103，缓存设备根据所请求的资源类别对用户设备进行鉴权，以获得用户设备的鉴权结果。
具体的，本申请实施例中，当缓存设备中存在用户设备所请求的资源，且用户设备所请求的资源为非权限类资源时，缓存设备向用户设备提供所请求的资源，减轻了通过所请求的资源的服务器获取资源时的网络负荷，提高了用户的使用体验。
具体的，本申请实施例中，当缓存设备中存在用户设备所请求的资源，且用户设备所请求的资源为权限类资源时，缓存设备需要 对用户设备进行鉴权。若用户设备鉴权通过，缓存设备会为用户设备提供所请求的资源；若用户鉴权不通过，缓存设备拒绝为用户设备提供所请求的资源，用户设备可以通过其他途径获取所请求的资源，例如，通过提供所请求的资源的服务器话费流量获取所请求的资源，本申请实施例对此不进行特别限定。
例如，用户设备在线请求观看S网站提供的最新的电影资源，该电影资源为权限类资源，虽然缓存设备重已经存储了该电影资源，但是缓存设备不会直接给用户设备提供该电影资源，而是需要对用户设备进行鉴权，只有用户设备鉴权通过，才会为用户设备提供该电影资源；若用户设备鉴权不通过，缓存设备拒绝为用户提供该电影资源。
本申请实施例中，缓存设备对用户设备进行鉴权的方法，可以包括但不限于以下两种实现方式：
第一种：缓存设备获取用户设备的鉴权信息，将鉴权信息发送给管理服务器，并接收管理服务器根据鉴权信息返回的用户设备的鉴权结果。
具体的，缓存设备可以代理用户设备，去管理服务器进行鉴权。用户设备将鉴权信息发送给缓存设备，缓存设备再将接收到的鉴权信息发送给管理服务器，由管理服务器根据用户设备的鉴权信息进行对用户设备的鉴权，同时，管理服务器鉴权结束后，将鉴权结果返回给缓存设备，缓存设备即可获得用户设备的鉴权结果。
第二种：缓存设备根据用户设备的鉴权信息，对用户设备进行鉴权，以获得用户设备的鉴权结果。
具体的，缓存设备可以代理提供所请求的资源的服务器的鉴权功能，对用户设备进行鉴权。用户设备将鉴权信息发送给缓存设备，缓存设备收到用户设备的鉴权信息后，直接代理提供所请求的资源的服务器的鉴权功能，根据接收到的鉴权信息对用户设备进行鉴权，并获取用户设备的鉴权是否通过的鉴权结果。
可以理解的是，用户设备的鉴权信息指的是对用户设备进行鉴 权时的必要信息。例如，用户设备请求S网站的权限类视频资源A时，用户设备的鉴权信息可以为用户设备登录S网站时所使用的用户名和密码信息。
需要说明的是，缓存设备对用户设备进行鉴权时的具体操作过程，可以根据实际需要在缓存设备中进行预设，例如，可以根据提供所请求的资源的服务器预设的验证方式进行鉴权操作，本申请实施例对此并不进行限定。
本申请实施例中，根据缓存设备对用户设备进行鉴权的鉴权结果，缓存设备可以为用户设备提供与用户设备鉴权结果相应的处理方式。
S104，若用户设备的鉴权结果为通过鉴权，缓存设备为用户设备提供所请求的资源。
具体的，本申请实施例中，若用户设备的鉴权结果为通过鉴权，缓存设备就会中断提供请求的资源的服务器为用户设备提供的资源，然后缓存设备将自身存储的请求的资源提供给用户设备。
举例说明，用户设备请求S网站的视频资源A时，视频资源A为权限类资源，缓存设备对用户设备进行鉴权。若用户设备鉴权通过，S网站准备为用户设备提供用户设备所请求的视频资源A时，缓存设备会中断S网站为用户设备提供的视频资源A，转由缓存设备将自身存储的视频资源A提供给用户设备。
具体的，本申请实施例中，若用户设备的鉴权结果为未通过鉴权，缓存设备拒绝为用户设备提供请求的资源。在一个具体的实现过程中，缓存设备拒绝为用户设备提供请求的资源时，缓存设备还可以向用户设备发送响应信息，用以通知用户设备，由于用户设备鉴权不通过，缓存设备不能为用户设备提供所请求的资源。
举例说明，用户设备请求S网站的视频资源A时，视频资源A为权限类资源，缓存设备对用户设备进行鉴权。若用户设备鉴权不通过，缓存设备不会为用户设备提供视频资源A，此时，缓存设备向用户设备发送响应信息，通知用户设备，由于用户设备鉴权不通 过，缓存设备不能为用户设备提供所请求的资源。
可以理解的是，虽然此时，缓存设备不为用户设备提供所请求的资源，用户设备可以通过其他方式获取所请求的资源，本申请对此不进行限定。因此，本申请实施例保证了有权限的用户设备可以获取到所请求的资源，而没有权限的用户设备无法获取到权限类资源，完成了对用户设备的分级分用户的服务，避免了资源所有权滥用和资源的不合理使用的问题。
具体的，本申请实施例中，若用户设备鉴权通过，缓存设备为用户设备提供所请求的资源时，缓存设备还可以采集为用户设备提供请求的资源的服务信息，并将采集到的服务信息发送给提供请求的资源的服务器，以便于服务器根据服务信息执行对应的操作，如，对用户设备进行计费等。
本申请实施例中，缓存设备采集的服务信息包括但不限于：用户设备的信息、请求的资源、请求的资源的下载时间和请求的资源的下载流量中至少一项。
本申请实施例中的一个技术方案具有如下有益效果：
本申请实施例的技术方案提供了一种资源下载方法，缓存设备接收用户设备发送的资源请求，资源请求中包含所请求的资源标识，然后，缓存设备根据资源标识，获取所请求的资源类别，从而，若所请求的资源属于权限类资源，缓存设备对用户设备进行鉴权，进而，若用户设备鉴权通过，缓存设备为用户设备提供所请求的资源。本申请实施例通过将缓存设备中的资源进行分类存储，当用户设备请求资源时，对用户设备进行鉴权，只有鉴权通过才会为用户设备提供所请求的资源，以此完成了资源安全下载的分级分用户服务，减轻了提供所请求的资源的服务器以及核心网的网络负荷，避免了现有技术中通过缓存设备提供资源下载服务时，无区别下载导致的资源所有权滥用以及资源的不合理使用的问题。
