以下，将通过具体实施例对本申请提供的事件订阅方法进行详细描述。
参照图2，本申请实施例提供一种事件订阅方法，执行于订阅者、事件源管理器及通道管理器所在的电子设备，该方法包括：
步骤102，电子设备中的订阅者在事件源管理器中查询事件源的IPC信息。
电子设备包括事件源管理器，事件源管理器中存储有事件源信息集合。
在一种可能的设计中，电子设备中的任一事件源初始化时，会将自身的事件源信 息注册存储至电子设备的事件源管理器中，参照图3，电子设备200的事件源202和事件源204在初始化时将事件源信息上传至电子设备的事件源管理器206中。
其中，事件源信息包括事件源ID、支持事件列表和IPC信息。
事件源标识信息表明事件源的身份。
支持事件列表记载了事件源可产生的事件。
IPC(Inter-Process Communication，进程间通信)信息包括事件源支持的通信方式、事件源所属的电子设备的IP地址和事件源的端口号。
其中，事件源所属的电子设备的IP地址和事件源的端口号表明了事件源的位置。
订阅一事件源中的事件的订阅者可通过事件源所属的电子设备的IP地址访问事件源所属的电子设备，在该电子设备中找到事件源的端口号，访问该端口号对应的端口，并经该端口通过事件源支持的通信方式向事件源订阅事件和接收该事件源发生的事件。
因此，电子设备中任一应用的订阅者进程中任一订阅者均可于事件源管理器的事件源信息集合内查询所需事件源的IPC信息。
步骤104，电子设备中的订阅者基于IPC信息通过通道管理器与事件源建立逻辑通道。
参照图3，电子设备200中具有通道管理器208和订阅者210，事件源202与订阅者210之间传输事件时，通道管理器208为两者建立逻辑信道，逻辑信道是供事件源202与订阅者210使用的抽象实体，由实体的物理信道所承载。
物理通道则是具体的物理连接，如tcp连接、udp连接或pipe连接等。一条物理通道具有承载多条逻辑通道的能力。
步骤106，在逻辑通道的连接模式为非直连模式的情况下，通道管理器将逻辑通道设置于第一物理通道之上，第一物理通道为订阅者所属订阅者进程内的其他订阅者订阅事件源的事件所使用的物理通道。
由于一条物理通道具有承载多条逻辑通道的能力，非直连模式下，在一个进程中的多个订阅者连接同一事件源时，可将多个订阅者的逻辑通道建立在同一个物理通道上，取代了相关技术中为每个订阅者建立一个物理通道以承载其逻辑通道的技术方案。
参照图3，订阅者进程中除了订阅者210至少还包括订阅者212、订阅者214，三者分别使用逻辑通道1、逻辑通道2和逻辑通道3连接事件源202。而这三条逻辑通道均建立在订阅者进程与事件源202的物理通道4。
由此，同一进程内的多个订阅者实现了物理通道的复用，大量减少了所需建立的物理通道的数量，从而减少了对系统资源的消耗，便于系统将有效资源提供给其他进程，整体提升了系统资源的有效利用率和工作效率。
步骤108，电子设备中的订阅者通过建立于第一物理通道之上的逻辑通道，向事件源发送订阅信息。
步骤110，电子设备中的订阅者通过建立于第一物理通道之上的逻辑通道，接收事件源针对订阅信息反馈的事件。
订阅信息包括订阅者ID和订阅者订阅事件的列表，订阅者将订阅信息发送至事件源，事件源即可将订阅者订阅的事件发送至订阅者ID，实现事件的下发。
在一种可能的设计中，电子设备中的订阅者在逻辑通道的连接模式为直连模式的情况下，新建第二物理通道，并将逻辑通道设置于第二物理通道之上。
逻辑通道的连接模式为直连模式的情况下，不同订阅者之间不复用相同物理通道，故可为直连模式下的订阅者建立新的物理通道。
在一种可能的设计中，事件源包括本设备事件源和/或跨设备事件源。
参照图4，电子设备200的事件源204可被电子设备300的订阅者302、订阅者310和订阅者312订阅，订阅者302、订阅者310和订阅者312分别使用通道管理器306中的逻辑通道5、逻辑通道6和逻辑通道7，逻辑通道5、逻辑通道6和逻辑通道7复用物理通道8。
其中，电子设备300的订阅者302在电子设备300的事件源管理器304中查询事件源204的IPC信息。
电子设备300的订阅者302基于事件源204的IPC信息，通过电子设备300的通道管理器306与事件源204建立逻辑通道，并将该逻辑通道建立在订阅者302所在进程与事件源204已建立的物理通道8之上，实现跨设备事件源与多个订阅者之间复用相同物理通道进行事件订阅和下发。
本设备事件源和跨设备事件源初始化时，均会将自身的事件源信息存储至自身所在电子设备的事件源信息集合中，不同电子设备的事件源管理器同步事件源信息集合。因此，电子设备中的订阅者可订阅本设备事件源和/或跨设备事件源。
在一种可能的设计中，电子设备的事件源管理器在自身的事件源信息集合中查询待订阅事件所属的第一事件源。
电子设备的事件源管理器判断订阅者的当前订阅权限是否满足第一预定条件。
基于当前订阅权限满足第一预定条件的情况，电子设备的事件源管理器在事件源信息集合中查询第一事件源的IPC信息，并发送至订阅者，以供订阅者根据该IPC信息与第一事件源建立逻辑通道进行事件的订阅和接收。
上述技术方案用于验证订阅者的资格。
订阅者可向事件源管理器发送事件订阅请求，该事件订阅请求中可指定待订阅事件或待订阅事件所属的事件源。
接着，电子设备的事件源管理器判断订阅者是否具有订阅该待订阅事件和/或订阅该第一事件源的资格，具体地，可判断订阅者的当前订阅权限是否满足第一预定条件，而第一预定条件为订阅者具有订阅该待订阅事件和/或订阅该第一事件源的资格的情况下其当前订阅权限所需要满足的最低条件。
在一种可能的设计中，第一预定条件为：当前订阅权限大于或等于待订阅事件的可订阅权限，和/或，当前订阅权限大于或等于第一事件源的可订阅权限。
当前订阅权限即订阅者自身的订阅权限，订阅权限的高低代表了订阅者可信赖程度的高低，而待订阅事件的可订阅权限代表了待订阅事件所能信赖的最低订阅权限，第一事件源的可订阅权限代表了第一事件源所能信赖的最低订阅权限。
因此，在订阅者自身的订阅权限大于或等于待订阅事件的可订阅权限的情况下，可认定订阅者达到了可被待订阅事件信赖的最低水平。
或者，在订阅者自身的订阅权限大于或等于第一事件源的可订阅权限的情况下， 可认定订阅者达到了可被第一事件源信赖的最低水平。
或者，在订阅者自身的订阅权限大于或等于待订阅事件的可订阅权限，并且订阅者自身的订阅权限大于或等于第一事件源的可订阅权限的情况下，可认定订阅者达到了可被待订阅事件和第一事件源共同信赖的最低水平。
此时，即可确定订阅者具有订阅第一事件源的待订阅事件的资格。
在一种可能的设计中，电子设备的事件源管理器在自身的事件源信息集合中查询符合预定筛选规则的第二事件源。
电子设备的事件源管理器判断订阅者的当前订阅权限是否满足第二预定条件。
基于当前订阅权限满足第二预定条件的情况，电子设备的事件源管理器在事件源信息集合中查询第二事件源的IPC信息，并发送至订阅者，以供订阅者根据该IPC信息与第二事件源建立逻辑通道进行事件的订阅和接收。
上述技术方案用于验证订阅者的资格。
订阅者可向事件源管理器发送事件订阅请求，该事件订阅请求中不指定待订阅事件或待订阅事件所属的事件源，而是指定预定筛选规则，或者，该事件订阅请求中不指定待订阅事件或待订阅事件所属的事件源，而是依赖于事件源管理器中的预定筛选规则在事件源管理器中的多个事件源中筛选出所需订阅事件的事件源。
其中，预定筛选规则可根据实际需求进行灵活设置。
比如，设置订阅者只能订阅所在进程的事件源列表中的事件源，或者，设置订阅者只能订阅本设备事件源，或者，设置订阅者只能订阅跨设备事件源。当然，预定筛选规则还可以是根据实际需要灵活设置的任何其他筛选条件。
接着，电子设备的事件源管理器判断订阅者是否具有订阅该待订阅事件和/或订阅该第一事件源的资格，具体地，可判断订阅者的当前订阅权限是否满足第二预定条件，而第二预定条件为订阅者具有订阅该待订阅事件和/或订阅该第一事件源的资格的情况下其当前订阅权限所需要满足的最低条件。
在一种可能的设计中，第二预定条件为：当前订阅权限大于或等于第二事件源中待订阅事件的可订阅权限，和/或，当前订阅权限大于或等于第二事件源的可订阅权限。
当前订阅权限即订阅者自身的订阅权限，订阅权限的高低代表了订阅者可信赖程度的高低，而待订阅事件的可订阅权限代表了待订阅事件所能信赖的最低订阅权限，第二事件源的可订阅权限代表了第二事件源所能信赖的最低订阅权限。
因此，在订阅者自身的订阅权限大于或等于待订阅事件的可订阅权限的情况下，可认定订阅者达到了可被待订阅事件信赖的最低水平。
或者，在订阅者自身的订阅权限大于或等于第二事件源的可订阅权限的情况下，可认定订阅者达到了可被第二事件源信赖的最低水平。
或者，在订阅者自身的订阅权限大于或等于待订阅事件的可订阅权限，并且订阅者自身的订阅权限大于或等于第二事件源的可订阅权限的情况下，可认定订阅者达到了可被待订阅事件和第二事件源共同信赖的最低水平。
此时，即可确定订阅者具有订阅第二事件源的待订阅事件的资格。
