Description

A method, storage medium, device and system for caching gift panel messages

technical field

The invention relates to the technical field of live broadcast software development, in particular to a method, storage medium, device and system for caching gift panel messages.

Background technique

With the rapid development of mobile terminals, especially mobile terminals, the live broadcast industry is becoming more and more popular, and many users like to watch live broadcasts through mobile terminal devices. In the process of watching live broadcasts, users often give gifts to their favorite anchors. Therefore, in the development and design of live broadcast software (such as Douyu live broadcast software), it is usually necessary to have the function of a gift panel.

The gift panel is mainly used for placing gifts. There are many view elements in the gift panel. Each view element needs to receive different messages and make different interface status updates. However, the arrival of the message is uncertain. It is possible that the message has arrived before the gift panel has been clicked. When we click to open the gift panel, we need a message that has arrived at the level, and the receiver of this message can only be received when there is a message. Only then will the function corresponding to the message be triggered. However, when the gift panel is opened, there is no message at this time (because the message has arrived before the gift panel has been clicked), therefore, the interface of the gift panel will be displayed abnormally due to the inability to obtain the latest news in time. .

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the above-mentioned deficiencies of the background technology, and provide a method, storage medium, device and system for caching the messages of the gift panel, which can effectively ensure the persistence of the messages of the gift panel and avoid abnormal display of the interface of the gift panel.

Message encapsulation: encapsulate each message that has arrived at the message receiver into an object of a self-defined message encapsulation class; the self-defined message encapsulation class includes a message name and a message body, and the message name is used to store the unique identifier of the message The message body is used to store the specific content of the message;

S2, message caching: cache all encapsulated messages into a key-value pair set; each encapsulated message corresponds to a key-value pair in the key-value pair set, and the key in the key-value pair corresponds to the encapsulated key-value pair The message name of the message, and the value in the key-value pair corresponds to the message body of the encapsulated message;

S3. Acquisition and use of message cache: When clicking on the gift panel, the content of the message to be used is retrieved from the set of key-value pairs; and the content of the acquired message is used to display the interface of the gift panel.

On the basis of the above technical solution, in step S2, all encapsulated messages are cached into a key-value pair set, which specifically includes the following operations:

S201, extracting its corresponding message name and message body from an encapsulated message;

S202, determine whether the extracted message name is empty or an empty string, if so, go to step S204; otherwise, go to step S203;

S203, cache the taken-out message name in the key of a key-value pair in the key-value pair set; cache the taken-out message body in the value of a key-value pair in the key-value pair set;

S204. Repeat steps S201-S203 until all the encapsulated messages have been cached in the key-value pair set.

On the basis of the above technical solution, in step S3, the content of the message to be used is retrieved from the key-value pair set, which specifically includes the following operations:

S301, sequentially extracting a key-value pair corresponding to a message from the key-value pair set;

S302, extract the message name of the message from the key of the key-value pair, and compare the message name with the message name of the message to be used, if the two are consistent, go to step S303; if the two are inconsistent, go to step S303 Step S304;

S303, extract the message body of the message from the value of the key-value pair, return the content in the message body as the content of the message that needs to be used, and end the extraction operation;

S304, determine whether all the key-value pairs corresponding to all messages in the key-value pair set have been taken out, if so, return the information that the message to be used has not been obtained; otherwise, return to step S301, and continue to take out the key corresponding to the next message value pair.

On the basis of the above technical solution, step S2 further includes the following operations: buffering all the encapsulated messages in a message queue; step S3 further includes the following operations: when clicking on the gift panel, take out the historical records that need to be obtained from the message queue the content of the message.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1, an embodiment of the present invention provides a method for caching a message on a gift panel, and the method includes the following steps:

Step S1, message encapsulation: encapsulate each message that has arrived at the message receiver into an object of a self-defined message encapsulation class, and the self-defined message encapsulation class (such as MsgWrapper) includes two pieces of information: a message name and a message body; wherein , the message name is a message code of type String (string), which is mainly used to store the unique identifier of the message, which can distinguish different types of messages; the message body is the information data message of Object type, which is mainly used to store The specific content of the message.

It can be understood that there are many kinds of messages in the gift panel, such as room information messages for entering a room, user information messages for user login, room type information messages for the room in which they are located, or bullet screen information messages in the room, etc. At present, in order to distinguish the above-mentioned various types of messages, the solution usually adopted is to distinguish according to the data content of the messages. That is to say, it is necessary to determine whether the content of the message is room information, or not user login information. Although this scheme can distinguish different messages in principle, its biggest drawback is that it needs to determine what message each message is, and it needs to read and parse the content of the message to know what the message is. It will take too much judgment time, which will cause the program execution speed to slow down.

In view of the above situation, the embodiment of the present invention designs a custom message encapsulation class MsgWrapper, and the custom message encapsulation class MsgWrapper includes two pieces of information: one is the message name and the other is the message body. The unique identifier of the message is stored in the message name, and different types of messages can be distinguished by the unique identifier. In this way, in the later operation, the type of the message can be known only by reading the message name in the message encapsulation class MsgWrapper, which saves the time overhead of parsing the specific content of the message and improves the execution speed of the program. In addition, the message body is the information data message of the Object type. The reason why the Object type is used to store the specific content of the message is because Object is the parent class of all classes. According to the characteristics of the object-oriented language, the parent class object can be used to receive subclass objects. , so the Object type can be used to receive all kinds of message content.

Further, in an implementation manner, when a message is encapsulated into an object of a custom message encapsulation class, the generation process of the message name corresponding to each message is: by calling the hash code value acquisition function getHashCode in the message message to generate the message name corresponding to each message. It can be understood that each message has a unique HashCode (hash code value), and the HashCode of the message cannot be repeated. In this way, using the unique feature of HashCode, we can use the HashCode of the message to distinguish specific message types. That is to say, the HashCode of the message is the unique identifier of the message stored in the message name.

Step S2, message caching: cache all encapsulated messages into a key-value pair set (such as Map); each encapsulated message corresponds to a key-value pair, and the key in the key-value pair corresponds to the encapsulated message The message name of the key-value pair corresponds to the message body of the encapsulated message.

It is understandable that the arrival of the message in the gift panel is uncertain, but when we go to open the gift panel, we need some information about the room and the user. And the message of room and user related information may have arrived before opening the gift panel. Therefore, in order to obtain the message that arrived in advance, we need to cache the message.

In the embodiment of the present invention, all the encapsulated messages are cached in a key-value pair set Map, and the key-value pair structure in the key-value pair set Map can correspond to the message encapsulated into a custom message encapsulation class MsgWrapper; And, in the key-value pair collection Map, the key is unique (different), and the value can be the same. The key in the key-value pair corresponds to the message name in the message encapsulation class MsgWrapper, and the value in the key-value pair corresponds to the message body in the message encapsulation class MsgWrapper. By using the above-mentioned corresponding cache data structure, the cache of the message can be quickly realized, and the corresponding message can be easily and quickly obtained subsequently.

Specifically, in one embodiment, in step S2, all encapsulated messages are cached in a key-value pair set (such as Map), which specifically includes the following operations:

Step S201 , extract the corresponding message name and message body from a packaged message (ie, an object of the message package class MsgWrapper). In actual operation, the message name information in the object of the message encapsulation class MsgWrapper can be obtained by calling the message name obtaining function getName.

Step S202, judging whether the extracted message name is empty (null) or an empty string (""), if it is empty or an empty string, go to step S204; otherwise, go to step S203.

Step S203: Cache the retrieved message name in the key of a key-value pair in the key-value pair set (such as Map); cache the retrieved message body in the key of a key-value pair in the key-value pair set (such as Map); value. In actual operation, the message name and message body of a message can be cached into a key-value pair in the key-value pair set by calling the key-value pair writing function put(key, value).

Step S204: Repeat steps S201-S203 until all the encapsulated messages have been cached in a key-value pair set (eg Map).

Step S3, the acquisition and use of the message cache: when the gift panel is clicked (opened), the content of the message to be used is taken out from the key-value pair collection (such as Map); interface display.

Specifically, in one embodiment, in step S3, the content of the message to be used is retrieved from the key-value pair collection (such as Map), which specifically includes the following operations:

Step S301 , sequentially extracting a key-value pair corresponding to a message from a key-value pair set (such as a Map).

Step S302, take out the message name of the message from the key of the key-value pair, and compare the message name with the message name of the message to be used, if the two are consistent, go to step S303; if the two are inconsistent, go to step S303. Go to step S304.

Step S303, take out the message body of the message from the value of the key-value pair, return the content in the message body as the content of the message to be used, and end the take-out operation (that is, end taking out the required use from the key-value pair set) action on the content of the message). In actual operation, the loop operation of taking out the message can be ended by calling the break function.

Step S304, judging whether all the key-value pairs corresponding to all the messages in the key-value pair set have been taken out, and if so, it indicates that after traversing all the key-value pairs in the key-value pair set, the message that needs to be used is still not found, and the return is not obtained. to the information of the message to be used; otherwise, return to step S301, and continue to extract the key-value pair corresponding to the next message. In actual operation, when the information about the message that needs to be used is not obtained, you can directly return a null object to indicate that the message that needs to be used is not obtained.

It can be understood that, when implementing the loop operations in steps S301 to S304, a For loop statement can be used to implement, which not only has high loop efficiency but also is simple and convenient to implement.

Further, in actual operation, some messages need their history information when they are used, and the messages will be overwritten when the key-value pair set is used to cache messages, that is to say, messages with the same message name (that is, the same type of message) messages) will be overwritten and stored, so that we cannot obtain historical message record information. In order to solve the problem of needing to obtain messages of historical records, a message queue can be added for buffering. The message queue stores the messages that need history information in the message queue through the push method. When we take out the message, we call the pop method to get the message. Since all messages are cached by means of message queues, messages with the same message name will also be stored as an element in the queue. Therefore, all messages of the same type can be cached in this way, that is to say, the historical message record information of all messages is cached. Because the two caching mechanisms of message queue and key-value pair collection are commonly used in the gift panel, when the gift panel displays the interface, if you need to use those messages that require history information, you can get them from the message queue, which improves the gift of gifts. The efficiency of the panel interface display also further avoids the abnormal display of the gift panel interface.

Based on the above design, in an embodiment, step S2 further includes the following operation: buffering all the encapsulated messages into a message queue. On this basis, step S3 further includes the following operations: when the gift panel is clicked (opened), the content of the message that needs to obtain the history record is taken out from the message queue.

Corresponding to the above-mentioned method for caching gift panel messages, an embodiment of the present invention further provides a storage medium on which a computer program is stored, and when the computer program is executed by a processor, the method for caching gift panel messages in the foregoing embodiments can be implemented A step of. It should be noted that the storage medium includes U disk, mobile hard disk, ROM (Read-Only Memory, read-only memory), RAM (Random Access Memory, random access memory), magnetic disk or optical disk and other various programs that can store program codes medium.

Specifically, the specific process for the message caching module to cache all encapsulated messages into a key-value pair set is as follows: extracting the corresponding message name and message body from an encapsulated message, and determining whether the extracted message name is not Empty or empty string; if not, cache the retrieved message name in the key of a key-value pair in the key-value pair set, and cache the retrieved message body in a key-value pair in the key-value pair set If yes, continue to cache the next encapsulated message until all encapsulated messages have been cached in the key-value pair set.

The message acquisition and use module is used to: when the gift panel is clicked, retrieve the content of the message to be used from the key-value pair set; and use the content of the acquired message to display the interface of the gift panel. Specifically, the specific process for the message acquisition and use module to extract the content of the message to be used from the key-value pair set is: sequentially extracting a key-value pair corresponding to a message from the key-value pair set; The message name of the message is extracted from the key of the key, and the message name is compared with the message name of the message to be used. The content in the body is returned as the content of the message to be used, and the fetching operation is ended; if the two are inconsistent, it is judged whether all the key-value pairs corresponding to all the messages in the key-value pair set have been fetched, and if so, return not fetched to the information of the message to be used; otherwise, continue to extract the key-value pair corresponding to the next message for comparison.

Further, in order to solve the problem of needing to obtain the messages of the historical records, in an embodiment, a message queue is added to cache all the encapsulated messages. Specifically, the message caching module is also used to: cache all the encapsulated messages in a message queue; the message acquisition and use module is also used to: when the gift panel is clicked, take out the messages that need to be acquired from the message queue The content of the message in the history.
