Event producers are also referred to as event sources or publishers, and consumers are also referred to as subscribers. With the development of intelligent terminals, more and more mobile intelligent devices and smart home devices are provided in the hands of users, various application programs are also endless, and subscribers in the application programs need to pay attention to a large number of events. The logical channels that transport events between event sources and subscribers depend on the physical channels of the entities.

Hereinafter, the event subscription method provided by the present application will be described in detail by specific embodiments.

Referring to fig. 2, an embodiment of the present application provides an event subscription method executed in an electronic device in which a subscriber, an event source manager, and a channel manager are located, the method including:

in step 102, a subscriber in the electronic device queries IPC information of an event source in an event source manager.

The electronic equipment comprises an event source manager, wherein an event source information set is stored in the event source manager.

In one possible design, when any event source in the electronic device is initialized, the event source information of the electronic device is registered and stored in an event source manager of the electronic device, and referring to fig. 3, the event source 202 and the event source 204 of the electronic device 200 upload the event source information to the event source manager 206 of the electronic device at the time of initialization.

The event source information comprises an event source ID, a support event list and IPC information.

The event source identification information indicates the identity of the event source.

The list of supporting events describes the events that the event source can generate.

The IPC (Inter-Process Communication) information includes a Communication method supported by the event source, an IP address of the electronic device to which the event source belongs, and a port number of the event source.

The IP address of the electronic equipment to which the event source belongs and the port number of the event source indicate the position of the event source.

A subscriber who subscribes an event in an event source can access the electronic equipment to which the event source belongs through the IP address of the electronic equipment to which the event source belongs, find the port number of the event source in the electronic equipment, access the port corresponding to the port number, subscribe the event to the event source through the port in a communication mode supported by the event source and receive the event generated by the event source.

Therefore, any subscriber in the subscriber process of any application in the electronic equipment can inquire the IPC information of the required event source in the event source information set of the event source manager.

In step 104, a subscriber in the electronic device establishes a logical channel with the event source through the channel manager based on the IPC information.

Referring to fig. 3, the electronic device 200 has a channel manager 208 and a subscriber 210, and when an event is transmitted between an event source 202 and the subscriber 210, the channel manager 208 establishes a logical channel for the two, and the logical channel is an abstract entity used by the event source 202 and the subscriber 210 and is carried by a physical channel of the entity.

A physical channel is a specific physical connection, such as a tcp connection, a udp connection, or a pipe connection. One physical channel has the capability to carry multiple logical channels.

Step 106, under the condition that the connection mode of the logical channel is the non-direct connection mode, the channel manager sets the logical channel on a first physical channel, wherein the first physical channel is a physical channel used by other subscribers in the subscriber process to which the subscriber belongs to subscribe to the event of the event source.

Because one physical channel has the capacity of bearing a plurality of logical channels, in a non-direct connection mode, when a plurality of subscribers in one process are connected with the same event source, the logical channels of the plurality of subscribers can be established on the same physical channel, and the technical scheme that one physical channel is established for each subscriber to bear the logical channels in the related technology is replaced.

Referring to fig. 3, the subscriber process includes at least a subscriber 212 and a subscriber 214 in addition to the subscriber 210, and the three connect to the event source 202 by using logical channel 1, logical channel 2 and logical channel 3, respectively. And the three logical channels are all established in the physical channel 4 between the subscriber process and the event source 202.

Therefore, multiple subscribers in the same process realize the multiplexing of the physical channels, and the number of the physical channels required to be established is greatly reduced, so that the consumption of system resources is reduced, the system is convenient to provide effective resources for other processes, and the effective utilization rate and the working efficiency of the system resources are integrally improved.

In step 108, a subscriber in the electronic device sends subscription information to the event source through a logical channel established on the first physical channel.

In step 110, a subscriber in the electronic device receives an event fed back by an event source for subscription information through a logical channel established above a first physical channel.

The subscription information comprises a subscriber ID and a list of events subscribed by the subscriber, the subscriber sends the subscription information to the event source, and the event source can send the events subscribed by the subscriber to the subscriber ID to realize the issuing of the events.

In one possible design, a subscriber in the electronic device creates a second physical channel and sets the logical channel on the second physical channel when the connection mode of the logical channel is the direct connection mode.

Under the condition that the connection mode of the logic channel is the direct connection mode, different subscribers do not multiplex the same physical channel, so that a new physical channel can be established for the subscribers in the direct connection mode.

Referring to fig. 4, event sources 204 of electronic device 200 may be subscribed by subscribers 302, 310, and 312 of electronic device 300, with subscribers 302, 310, and 312 using logical channel 5, logical channel 6, and logical channel 7, respectively, in channel manager 306, and logical channel 5, logical channel 6, and logical channel 7 multiplexing physical channel 8.

Therein, a subscriber 302 of the electronic device 300 queries the event source manager 304 of the electronic device 300 for IPC information of the event source 204.

The subscriber 302 of the electronic device 300 establishes a logical channel with the event source 204 through the channel manager 306 of the electronic device 300 based on the IPC information of the event source 204, and establishes the logical channel on the physical channel 8 established by the process where the subscriber 302 is located and the event source 204, so that event subscription and event distribution are performed by multiplexing the same physical channel between the cross-device event source and multiple subscribers.

When the device event source and the cross-device event source are initialized, the event source information of the device event source and the cross-device event source are stored into the event source information set of the electronic device where the device event source and the cross-device event source are located, and the event source managers of different electronic devices synchronize the event source information sets. Thus, subscribers in an electronic device may subscribe to local device event sources and/or cross-device event sources.

In one possible design, an event source manager of the electronic device queries a first event source to which an event to be subscribed belongs in an event source information set of the event source manager.

An event source manager of the electronic equipment judges whether the current subscription authority of the subscriber meets a first preset condition.

Based on the condition that the current subscription authority meets the first preset condition, an event source manager of the electronic equipment inquires IPC information of the first event source in the event source information set and sends the IPC information to the subscriber so that the subscriber establishes a logic channel with the first event source according to the IPC information to subscribe and receive events.

The technical scheme is used for verifying the qualification of the subscriber.

The subscriber can send an event subscription request to the event source manager, and the event subscription request can specify an event to be subscribed or an event source to which the event to be subscribed belongs.

Then, the event source manager of the electronic device determines whether the subscriber qualifies to subscribe to the event to be subscribed and/or to subscribe to the first event source, and specifically, may determine whether the current subscription authority of the subscriber satisfies a first predetermined condition, where the first predetermined condition is a minimum condition that the current subscription authority of the subscriber needs to satisfy in a case that the subscriber qualifies to subscribe to the event to be subscribed and/or to subscribe to the first event source.

In one possible design, the first predetermined condition is: the current subscription authority is larger than or equal to the subscribeable authority of the event to be subscribed, and/or the current subscription authority is larger than or equal to the subscribeable authority of the first event source.

The current subscription authority is the subscription authority of the subscriber, the high or low of the subscription authority represents the credibility of the subscriber, the subscribeable authority of the event to be subscribed represents the lowest subscription authority that can be trusted by the event to be subscribed, and the subscribeable authority of the first event source represents the lowest subscription authority that can be trusted by the first event source.

Therefore, in the case that the subscription authority of the subscriber is greater than or equal to the subscribeable authority of the event to be subscribed, the subscriber can be considered to reach the lowest level which can be trusted by the event to be subscribed.

Alternatively, in the case that the subscription authority of the subscriber itself is greater than or equal to the subscribeable authority of the first event source, the subscriber can be considered to reach the lowest level that can be trusted by the first event source.

Or, in the case that the subscription authority of the subscriber is greater than or equal to the subscribeable authority of the event to be subscribed and the subscription authority of the subscriber is greater than or equal to the subscribeable authority of the first event source, the subscriber can be considered to reach the lowest level that can be trusted by the event to be subscribed and the first event source together.

At this point, it can be determined that the subscriber qualifies to subscribe to the event to be subscribed of the first event source.

In one possible design, the event source manager of the electronic device queries a second event source meeting a predetermined filtering rule in its own event source information set.

Based on the condition that the current subscription authority meets a second preset condition, an event source manager of the electronic equipment inquires IPC information of a second event source in an event source information set and sends the IPC information to a subscriber so that the subscriber establishes a logic channel with the second event source according to the IPC information to subscribe and receive events.

The technical scheme is used for verifying the qualification of the subscriber.

The subscriber can send an event subscription request to the event source manager, where the event subscription request specifies not the event to be subscribed or the event source to which the event to be subscribed belongs, but a predetermined filtering rule, or the event subscription request does not specify the event to be subscribed or the event source to which the event to be subscribed belongs, but rather, the event source to which the event to be subscribed belongs is filtered out from the multiple event sources in the event source manager depending on the predetermined filtering rule in the event source manager.

The preset screening rules can be flexibly set according to actual requirements.

For example, a subscriber may be set to subscribe to an event source in the event source list of the process, or the subscriber may be set to subscribe to the event source of the device, or the subscriber may be set to subscribe to the event source across devices. Of course, the predetermined filtering rule may also be any other filtering condition flexibly set according to actual needs.

Then, the event source manager of the electronic device determines whether the subscriber qualifies to subscribe to the event to be subscribed and/or to subscribe to the first event source, and specifically, may determine whether the current subscription authority of the subscriber satisfies a second predetermined condition, where the second predetermined condition is a minimum condition that the current subscription authority of the subscriber needs to satisfy in a case that the subscriber qualifies to subscribe to the event to be subscribed and/or to subscribe to the first event source.

In one possible design, the second predetermined condition is: the current subscription right is larger than or equal to the subscribeable right of the event to be subscribed in the second event source, and/or the current subscription right is larger than or equal to the subscribeable right of the second event source.

The current subscription authority is the subscription authority of the subscriber, the high or low of the subscription authority represents the credibility of the subscriber, the subscribeable authority of the event to be subscribed represents the lowest subscription authority that the event to be subscribed can trust, and the subscribeable authority of the second event source represents the lowest subscription authority that the second event source can trust.

Alternatively, in the case that the subscription authority of the subscriber itself is greater than or equal to the subscribeable authority of the second event source, the subscriber can be considered to reach the lowest level that can be trusted by the second event source.

Or, in the case that the subscription authority of the subscriber is greater than or equal to the subscribeable authority of the event to be subscribed and the subscription authority of the subscriber is greater than or equal to the subscribeable authority of the second event source, the subscriber can be considered to reach the lowest level that can be trusted by the event to be subscribed and the second event source together.

At this point, it can be determined that the subscriber qualifies to subscribe to the event to be subscribed of the second event source.
