Description

调度方法、装置、介质及设备
本公开基于2021年03月31日提交中国专利局、申请号为202110352753.9，发明名称为“一种调度方法、装置、介质及设备”的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本公开作为参考。
技术领域
本公开实施例涉及但不限于一种调度方法、装置、介质及设备。
背景技术
相关技术中，服务器提供服务的出口带宽会小于网卡的出口带宽，主要原因为一部分的带宽流量消耗在内部调度上。以现有云分发缓存架构为例，每台服务器可能同时提供负载均衡器和缓存代理服务，当服务器接收到客户端或其他缓存代理的请求后，会根据请求的URL进行调度，将请求调度到提供缓存代理服务的服务器上，对于其中一个缓存代理来说，平均每接收4个请求，其中的3个请求可能是由其他服务器上的负载均衡器器调度过来的，在对请求进行响应后，其中的3个请求的响应也会原路返回至对应的负载均衡器所在的服务器，导致3/4的带宽消耗在了内部调度上。可见，由于架构的限制，相当大的一部分带宽消耗在了内部调度上，浪费了缓存代理的带宽，限制了单机的服务能力。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
为克服相关技术中存在的问题，本公开提供一种调度方法、装置、介质及设备。

接收请求端的请求；
确定所述请求的格式是否符合预设格式；
若所述请求的格式不符合预设格式，确定所述请求的URL为原始URL，根据所述原始URL确定对应的目标代理服务器；
当所述目标代理服务器不是本机代理服务器时，构造预设格式的重定向信息，发送至所述请求端。
在一些示例性的实施例中，所述构造预设格式的重定向信息包括：
基于所述目标代理服务器的地址、所述原始URL，按预设规则构造为重定向信息。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
代理服务器包括负载均衡器(简称SLB)和缓存代理(简称cache)，负载均衡器和缓存代理可以在同一代理服务器上，也可以位于不同代理服务器上。负载均衡器用于接收请求，对接收到的请求进行负载均衡调度，确定请求调度至的目标代理服务器，例如可以对请求的原始URL进行一致性hash计算，进而确定目标代理服务器，实现负载均衡；缓存代理用于缓存请求对应的资源文件，并对请求进行响应。为表述清楚，当负载均衡器调度后的落点位于同一台代理服务器的缓存代理上时，将目标代理服务器称为本机代理服务器。
相关技术中，当前代理服务器的负载均衡器接收请求端的请求，根据预设算法以及请求的原始URL，确定目标代理服务器。当目标代理服务器不是本机代理服务器时，需要对请求进行调度。调度方法为将请求转发至目标代理服务器，目标代理服务器将缓存代理中的与原始URL对应的资源文件发送给当前代理服务器，再由当前代理服务器将资源文件发送至请求端。导致代理服务器的出口带宽有相当大的一部分消耗在了内部调度上。
本公开提供一种调度方法。
图1是根据一示例性实施例示出的调度方法的流程图。参考图1，调度方法应用于代理服务器，包括：
步骤S11，接收请求端的请求。
步骤S12，确定请求的格式是否符合预设格式。
步骤S13，若请求的格式不符合预设格式，确定请求的URL为原始URL，根据原始URL确定对应的目标代理服务器。
步骤S14，当目标代理服务器不是本机代理服务器时，构造预设格式的重定向信息，发送至请求端。
在步骤S11中，在云分发系统中，客户端发送请求，请求到达边缘节点，由边缘节点查询缓存中是否缓存了该请求对应的资源文件，如果有对应的资源文件，由边缘节点响应客户端的请求，如果边缘节点没有缓存客户端请求的资源文件，边缘节点会向源站发起请求，下载对应的资源文件，并缓存。此时客户端为请求端，边缘节点为响应端。当云分发系统比较大时，如果边缘节点没有缓存客户端请求的资源文件，则会向上一级节点(父节点)发起请求，由上一级节点，使用缓存的资源文件或向源站下载资源文件响应边缘节点请求，此时边缘节点为请求端，父节点为响应端。特殊情况下，云分发系统可以有多级节点，发出请求的节点为请求端，响应请求的节点为响应端，在此不再一一详述。在本公开的一实施例中，代理服务器为响应端中典型的服务器，用于接收请求端的请求。
在步骤S12中，代理服务器接收到的请求可以为客户端发送的原始请求，也可以为下级节点转发的客户端的原始请求，或者为下级节点根据客户端的请求而主动发起的请求。在本公开中，将客户端原始请求中的URL定义为原始URL。另外，在本公开中，代理服务器包括负载均衡器和缓存代理，负载均衡器需要对接收到的请求进行调度时，代理服务器可以向请求端发送重定向信息。请求端向目标代理服务器发送重定向信息作为重定向请求，重定向请求与原始请求的格式不同，因此，代理服务器可以对请求的格式进行判断，确定请求的格式是否符合预设格式。在本实施例中，符合预设格式的请求为重定向请求，不符合预设格式的请求为客户端原始请求或者下级节点转发的客户端原始请求，或者为下级节点根据客户端的原始请求而主动发起的请求。
在步骤S13中，若请求的格式不符合预设格式，确定请求的URL为原始URL，根据原始URL确定对应的目标代理服务器。如果请求的格式不符合预设格式，说明该请求为客户端的原始请求，或者下级节点转发的客户端的请求，或者为下级节点根据客户端的原始请求而主动发起的请求，请求的URL为原始URL。例如，代理服务器接收到的客户端的请求，或 者，上级节点中的代理服务器接收到的下级节点转发的客户端的请求，或者上级节点中的代理服务器接收到的下级节点根据客户端的原始请求而主动发起的请求。代理服务器根据原始URL确定目标代理服务器。
在步骤S14中，当目标代理服务器不是本机代理服务器时，需要对请求进行调度。而调度方法为构造预设格式的重定向信息，发送至请求端。请求端向目标代理服务器发送重定向信息，作为重定向请求，向目标代理服务器请求资源文件。
本实施例中，当需要对请求进行调度时，当前代理服务器不再将请求转发至目标代理服务器，而是发送重定向信息给请求端。请求端可以向目标代理服务器发送重定向请求，直接从目标代理服务器获取请求的资源文件，可见，当前代理服务器不需向目标代理服务器转发请求，目标代理服务器也不需将资源文件发送至当前代理服务器，再经当前代理服务器提供给请求端，减少了内部调度的消耗。
在一实施例中，根据原始URL确定对应的目标代理服务器，包括：对原始URL根据预设的一致性哈希算法确定对应的目标代理服务器。对原始URL进行一致性hash计算，确定原始URL对应的目标代理服务器。在云分发系统中，节点中存在多台缓存代理，可以对客户端的请求进行负载均衡，本公开中，代理服务器对原始URL进行一致性hash计算，根据计算结果，确定落点所在的代理服务器为目标代理服务器，以提高请求的命中率。
在一实施例中，当目标代理服务器为本机代理服务器时，响应请求的资源文件。当前代理服务器的负载均衡器根据原始URL确定目标代理服务器为本机代理服务器时，由本机的缓存代理响应请求的资源文件。例如根据一致性hash计算的结果，如果目标代理服务器为本机代理服务器，当前代理服务器将该请求发送给本机服务器上的缓存代理，由本机缓存代理响应该请求的资源文件。这样，如果接收请求的负载均衡器和计算出的缓存代理位为同一代理服务器，可以通过共享内存等方式传递数据。资源文件由当前代理服务器直接向请求端响应，不需要经过其他代理服务器转发，不会产生内部调度的消耗。
在一实施例中，构造预设格式的重定向信息包括：
基于目标代理服务器的地址、原始URL，按预设规则构造为重定向信息。
当前代理服务器根据原始URL确定对应的目标代理服务器后，当目标代理服务器不是本机代理服务器时，需要对请求进行调度。本实施例中，调度方法为构造重定向信息，将重定向信息携带于响应消息中发送至请求端，重定向信息中包括目标代理服务器的地址，以使请求端向目标代理服务器发起请求；重定向信息中还包括原始URL，以便目标代理服务器使用缓存的资源文件，对原始请求进行响应。
目标代理服务器的地址，原始URL可以明文的形式加入重定向信息中，也可以加密的形式加入重定向信息中。因此可以根据需要设定预设规则，确定是否需要对目标代理服务器的地址、原始URL进行加密，如何加密等。对目标代理服务器的地址加密，可以提高代理服务器的安全性，防止地址泄露。对原始URL加密，可以提高信息安全。
在一实施例中，基于目标代理服务器的地址、原始URL，按预设规则构造为重定向信息包括：
将原始URL和/或目标代理服务器的地址加密为加密信息，并将加密信息填充到所述重定向信息中。在本实施例中，代理服务器的负载均衡器可以对原始URL进行加密，包括对整个原始URL进行加密，或者对原始URL中的域名进行加密；也可以对目标代理服务器的地址进行加密；还可以将原始URL和目标代理服务器的地址同时加密，加密为加密信息后，将加密信息填充到重定向响应消息中。例如，目标代理服务器为SLB-2服务器，原始请求为http://A域名/1.apk，重定向响应消息格式如下http://SLB-2服务器IP/加密信息(A域名)/1.apk。SLB-2服务器IP为目标代理服务器的地址，加密信息(A域名)为对原始URL中的域名信息进行加密。
再如，当前代理服务器构造重定向信息，并指定重定向的目标地址。重定向信息包括加密的目标代理服务器的地址，当前代理服务器将重定向信息携带进响应消息，发送至请求端，请求端接收到该重定向信息后，不需要对加密的消息进行解密，只需要进行重定向跟随，即跟随该重定向信息，将重定向信息发送至指定的目标地址，例如可以是DNS服务器，由DNS服务器对加密的目标代理服务器的地址进行解析，最后将请求发送至目标代理服务器。
对重定向信息中的原始URL、目标代理服务器的地址等关键信息进行加密，即使重定向信息在传输过程中被劫持，劫持者也无法获知加密的内容。可以有效地提高信息的安全性和代理服务器的安全性，达到防篡改或恶意攻击的目的。
在一实施例中，调度方法还包括：若请求的格式符合预设格式，获取请求的原始URL；根据原始URL响应所述请求的资源文件。
如果当前代理服务器接收到的请求格式符合预设格式，说明该请求既不是客户端的原始请求，也不是下级节点转发的客户端的请求或下级节点根据客户端的请求而主动发起的请求，而是其他代理服务器重定向后的请求，该请求的URL是经过其他代理服务器处理后的URL，需要从处理后的URL中获取原始URL。由于该请求为预设格式的重定向请求，说明该请求是其他代理服务器接收到原始请求后，对原始URL进行一致性hash计算后，根据一致性hash计算的结果，确定当前代理服务器为目标代理服务器后，重定向到当前代理服务器的请求。 根据预设的负载均衡算法，对于同样的URL，在不同代理服务器上进行哈希计算的结果也是相同的，其落点必然为同一个缓存代理。即该原始URL是由当前代理服务器进行响应的。当前代理服务器使用缓存代理中的资源文件对请求端进行响应。当代理服务器接收到重定向格式的请求后，可以在获取到原始URL后，直接向请求端响应资源文件，加快响应速度。
在一实施例中，调度方法还包括：若请求的格式符合预设格式，获取请求的原始URL；根据原始URL确定对应的目标代理服务器；当目标代理服务器为本机代理服务器时，响应所述请求的资源文件；当目标代理服务器不是本机代理服务器时，丢弃所述请求。
如果当前代理服务器接收到的请求格式符合预设格式，请求为重定向格式的请求，在正常情况下，当前代理服务器可以直接向请求端响应资源文件。但由于节点中的多个代理服务器可能同时执行多个不同服务，除了在响应资源文件请求的服务中会产生重定向信息，其他服务也有可能产生重定向信息，例如IP纠错服务产生的重定向信息，此时可能无法响应正确的内容。因此在本实施例中，当前代理服务器获取请求中的原始URL，再次对重定向请求中的原始URL进行一致性hash计算，如果该请求为正常的重定向响应消息，其结果的落点必定在本机服务器，也就是说计算出的目标代理服务器一定为当前代理服务器，由当前代理服务器向请求端响应资源文件。如果当前代理服务器根据上述重定向请求中的原始URL计算出的目标代理服务器不是当前代理服务器，该请求有可能是其他代理服务器的其他服务产生的重定向信息，例如IP纠错服务产生的重定向信息。为了避免多次重定向影响响应时间，当前代理服务器不再根据计算结果发送重定向信息，而是将请求丢弃。本实施例中，即可以对正常重定向请求进行快速响应，又可以避免其他服务的重定向请求影响正常的请求。
在一实施例中，获取请求的原始URL包括：
解密重定向信息中的加密信息，获取原始URL。当请求为重定向信息，且对原始URL进行加密处理后，代理服务器接收到请求后，对加密的原始URL进行解密，获取加密的内容。加密的内容只有代理服务器能够解密，防止用户信息泄露，增加安全性。
下面通过具体实施例对本公开中的调度方法进一步说明。
具体实施例一
步骤1：请求端发送请求http://A域名/1.apk。
步骤2：代理服务器SLB-1负载均衡器接收请求。
步骤3：代理服务器SLB-1判断该请求的格式是否符合预设格式，经过判断，该请求的格式不符合预设格式，请求的URL为原始URL。
步骤4：代理服务器SLB-1根据预设的一致性hash算法和原始URL，计算出该URL对应的资源文件在代理服务器SLB-2上的cache中，目标服务器为代理服务器SLB-2。于是SLB-1根据代理服务器SLB-2的地址和原始URL，及预设的规则，构造重定向信息，预设的规则为对URL中的域名加密。重定向信息格式如下：http://SLB-2服务器IP/加密信息(A域名)/1.apk。将构造的重定向信息置入302响应消息中，发送至请求端。
步骤5：请求端接收到上述302响应消息，进行重定向跟随，根据302响应消息中的重定向信息发送重定向请求消息至目标代理服务器SLB-2以获取响应内容，具体的，发送http://SLB-2服务器IP/加密填充(A域名)/1.apk至SLB-2所在服务器。
步骤6：代理服务器SLB-2收到请求端发送的请求后，判断其格式符合预设格式，进行请求的剥离与解密还原，得到加密信息中的原始原始URL，由代理服务器SLB-2本机cache将对应的资源文件响应给请求端。
通过以上实施例可知，应用本公开中的调度方法，代理服务器的负载均衡器需要度对请求进行调度时，通过发送重定向信息，并将请求的原始URL对应的目标代理服务器的地址添加入重定向信息中，指示请求端向目标代理服务器发起重定向请求，并从目标代理服务器获取请求的资源文件。请求信息和资源文件不需要在代理服务器之间调度和传递，实现负载均衡的同时，有效较少内部调度导致的带宽浪费，提高单机服务能力。
