Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
FIG. 1 illustrates a flow 100 of one embodiment of a method for unified reception of broadcast messages according to the present application. The method for uniformly receiving the broadcast messages comprises the following steps:
In the present embodiment, the execution subject of the method of uniformly receiving broadcast messages may receive broadcast messages of a target application.
Typically, the broadcast message is delivered to all the IPs involved in the identification segment with the IP address identifying the segment as all 1's as the broadcast address. Here, the improvement is that the target application installed on the terminal device uniformly receives the broadcast message, and the broadcast message is not directly received by each service layer of the target application. Therefore, the method can be realized by only deploying a set of codes for receiving the broadcast messages in the target application, and the codes for receiving the broadcast messages do not need to be dispersedly deployed in each service layer, so that the codes are more organized, unified management can be realized, the code maintenance is convenient, and unnecessary performance loss caused by code repetition is reduced.
It should be noted that the target application may be any application installed on the terminal device, such as a wireless access point management application.
In this embodiment, the execution subject may create an event message corresponding to the broadcast message. That is, the broadcast message is changed to an event message, remaining unchanged in content. Wherein the event message can be distributed identically through the target application internal event bus.
In this embodiment, the execution subject may search for a service of the registration event message. Generally, for a service that needs to listen to an event message, it may be registered in advance, so that the execution body determines the service that needs to listen to the event message.
In this embodiment, the execution agent may send the event message to a service that registers the event message. The number of services to which the event message is registered may be plural, and the execution body may distribute the event message to the services.
According to the method for uniformly receiving the broadcast messages, under the condition that the broadcast messages of the target application are received, event messages corresponding to the broadcast messages are created; then, the service registering the event message is searched and the event message is transmitted to the service registering the event message. The broadcast messages are received in a unified mode, then the broadcast messages are changed into event messages and distributed to all service layers, unified receiving of the broadcast messages can be achieved, repeated codes are reduced, and system overhead is reduced.
With continued reference to fig. 2, illustrated is a flow 200 that is yet another embodiment of a method of unified reception of broadcast messages in accordance with the present application. The method for uniformly receiving the broadcast messages comprises the following steps:
in step 201, a global broadcast receiver is registered when a target application is started.
In this embodiment, the execution subject of the method of uniformly receiving broadcast messages may register the global broadcast receiver when the target application is started. The global broadcast receiver may be configured to receive broadcast messages in a unified manner, instead of the broadcast receivers of the respective service layers of the target application. The whole target application only has the broadcast receiver, and the unified processing of the broadcast messages can be achieved.
Wherein the global broadcast receiver can be registered at the APP start-up by calling the following code:
AllBroadcastReceiverHelp.INSTANCE.registerReceiver(this)。
an event receiver is created by the service, step 202.
In this embodiment, for traffic in the target application that needs to listen to the event message, it may create an event receiver. Wherein the event receiver may be configured to receive the event message converted from the broadcast message.
In this embodiment, the event receiver of the service creation may be registered with the global broadcast receiver. Thus, the global broadcast receiver can determine the service that needs to listen to the event message after receiving the broadcast message. Specifically, the executing entity may store the object method of the event receiver in a Map (Map) list of the event sender when the event receiver is created, and may determine the service that needs to listen to the event message by traversing the Map list.
The service registers the event message by calling the following codes during initialization:
v/register event message (create event receiver and register to event sender)
At step 204, a broadcast message is received using the global broadcast receiver of the target application.
In this embodiment, the execution agent may receive the broadcast message using a global broadcast receiver of the target application.
Typically, the broadcast message is broadcast with an IP address identifying all 1's of the segment, identifying to the host all IP transmissions to which the segment relates. Here, the improvement is that the target application installed on the terminal device uniformly receives the broadcast message, and the broadcast message is not directly received by each service layer of the target application. Therefore, the method can be realized by only deploying a set of codes for receiving the broadcast messages in the target application, and the codes for receiving the broadcast messages do not need to be dispersedly deployed in each service layer, so that the codes are more organized, unified management can be realized, the code maintenance is convenient, and unnecessary performance loss caused by code repetition is reduced.
It should be noted that the target application may be any application installed on the terminal device, such as a wireless access point management application.
The code for the global broadcast receiver to uniformly receive the broadcast message may be as follows:
In this embodiment, the execution subject may create an event message corresponding to the broadcast message. That is, the broadcast message is changed to an event message, remaining unchanged in content. Wherein the event message can be distributed identically through the target application internal event bus.
Wherein, the code for transmitting the received broadcast message to become the event message for forwarding is as follows:
it should be noted that the number of broadcast messages is large, and only names of some broadcast messages are listed here as an example.
At step 206, the event receivers registered with the global broadcast receiver are searched.
In this embodiment, the execution agent may search for an event receiver registered to the global broadcast receiver.
In this embodiment, the execution subject may determine, based on the event receiver, a service that needs to listen to the event message. The service for creating the event receiver is the service that needs to listen to the event message.
And step 208, traversing the mapping list in the event sender, and calling the searched object methods of the event receiver one by one to send the event message.
In this embodiment, the execution main body may directly send the event message to the service in a callback manner. Specifically, the execution body may traverse a mapping list in the event sender, call the found object method of the event receiver one by one to send the event message, and transfer the parameter.
In some embodiments, the global broadcast receiver may be a process-level broadcast receiver, registering all broadcast messages that need to be listened to, and always existing within a process. The event sender may forward the broadcast message uniformly using the target application internal event bus. In this way, the broadcast messages are all received by one broadcast receiver and then distributed to the service layers using the event bus messages with low overhead.
As can be seen from fig. 2, compared with the corresponding embodiment of fig. 1, the flow 200 of the method for uniformly receiving broadcast messages in the present embodiment highlights a broadcast message receiving step and an event message sending step. Therefore, in the scheme described in this embodiment, a global broadcast receiver is registered when a target application is started, all broadcast messages required by the target application are received, the broadcast messages are changed into event messages, and the event messages are directly sent to corresponding services in a callback manner, so that the whole process of changing the broadcast messages into the event messages is completed once, uniform reception of the broadcast messages can be realized, repeated codes are reduced, and system overhead is reduced.
For ease of understanding, fig. 3 illustrates an application scenario diagram of the registration process. As shown in fig. 3, a global broadcast receiver R is created at the start of APP and registered. In addition, service a creates event listening and registers with global broadcast receiver R. Meanwhile, when the event receiver is created, the object method of the event receiver can be saved in the Map list of the event sender E, and one registration of the event is completed. Subsequently, the object methods can be called one by traversing the Map list, and parameters are transmitted.
Further, fig. 4 shows an application scenario diagram of the broadcast transmission process. As shown in fig. 4, the global broadcast receiver R may receive a broadcast message from an external broadcast. The broadcast message may become a corresponding event message. The event sender E sends an event message to the service a that has registered.
