DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The message transmission method, device, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0013] Figure 1 A message transmission method provided by an embodiment of the present application is shown, and the method can be performed by a server. In other words, the method can be performed by software or hardware installed on the server, and the method includes the following steps: Step 102: Obtain the target message to be transmitted.

[0014] In the embodiment of the present application, the transmission of instant messaging messages can be a client (sender)-server-client (receiver) transmission mode. That is, both the sender and the receiver's clients transmit messages through the server. It can also be a server-client (receiver) transmission mode, in which only the server and the receiver's client transmit messages. Therefore, in the embodiment of the present application, the target message sent by the sender's client can be obtained, such as a chat message, etc., or it can be a target message generated by the server, such as a system notification. The target message is not specifically limited here.

[0015] Step 104: When the target message includes a first sub-message without a file entity, the first sub-message is transmitted to the client via the MQTT protocol.

[0016] Specifically, when the target message includes a first sub-message without a file entity, the first sub-message can be transmitted to the client of the recipient through the MQTT protocol. Specifically, for example Figure 2 As shown in the communication architecture diagram, the first sub-message of the fileless entity transmitted through the MQTT protocol can be message signaling, text messages, system prompts, push messages, links (URLs), and other messages with high real-time and high concurrency. The MQTT protocol is a client-server based message publish / subscribe transmission protocol. Based on the publish / subscribe message model, a one-to-many message distribution mechanism can be provided, and the MQTT protocol is a low-overhead, low-bandwidth instant messaging protocol, and a real-time and reliable message service. The MQTT protocol is suitable for high-concurrency and high-real-time application scenarios, and has low transmission data and network bandwidth overhead. Figure 3 As shown in Figure 1, the MQTT protocol runs on top of the Transmission Control Protocol / Internet Protocol (TCP / IP) stack, and its position in the OSI reference model (7-layer model) is as follows: Figure 3 In addition, HTTP protocols such as Https or connection-oriented WebSocket can be used to replace HTTP protocols depending on different application environments.

[0017] Step 106: When the target message includes a second sub-message including a file entity, the second sub-message is transmitted to the client via the HTTP protocol.

[0018] Specifically, when the target message includes a second sub-message containing a file entity, the second sub-message can be transmitted to the receiving client through the HTTP protocol. The HTTP protocol has wide compatibility, is simple and fast to implement, has a connectionless feature that occupies little network resources, and supports the transmission of various types of messages. Figure 2 As shown in the figure, the second sub-message with the file entity can be a message with a large amount of data, such as pictures, audio, and video. The HTTP protocol can transmit data (HTML files, picture files, query results, etc.) based on the TCP / IP communication protocol. When the client requests a service from the server, it only needs to transmit the request method and path. The commonly used request methods are GET, HEAD, and POST. After the server processes the client's request and receives the client's response, it disconnects. HTTP allows the transmission of any type of data object. The HTTP protocol is suitable for the transmission of large amounts of information such as files, pictures, audio, and video in instant messaging scenarios, which do not require high real-time and reliability.

[0019] The message transmission method provided in the embodiment of the present application can enhance the reliability of message transmission by acquiring the target message to be transmitted; in the case where the target message includes a first sub-message without a file entity, transmitting the first sub-message to the client through the MQTT protocol; in the case where the target message includes a second sub-message with a file entity, transmitting the second sub-message to the client through the HTTP protocol. Combining the advantages of the characteristics of the two types of connection-oriented and connectionless communication protocols, the MQTT protocol and the HTTP protocol are applied to various business scenarios of instant messaging, and the decoupled transmission of the first sub-message and the second sub-message is realized, reducing the data delay overhead and ensuring the high performance of message transmission. The connection-oriented characteristics of the TCP / IP protocol family in the MQTT protocol are used to ensure the stability of the client-server message link, and the characteristics of the message publish / subscribe protocol in the MQTT protocol are used to ensure the reliability, lightness and speed of message signaling transmission. The HTTP protocol is used to ensure the safe delivery of message files by its wide compatibility characteristics for large message data transmission and its quick application landing. It can improve the timeliness of message communication delivery for large concurrent users, enhance the reliability of message transmission, reduce the pressure on the server for obtaining files, pictures, audio and video files, and provide timely feedback on client keep-alive, client status update and other links.

[0020] In an implementation, before obtaining the target message to be transmitted, the method further includes: monitoring the status of the client through the monitoring function of the MQTT protocol, where the status of the client includes: online, offline or suspended.

[0021] For example Figure 2As shown, in the embodiment of the present application, some enhanced functions are implemented based on the MQTT protocol and the HTTP protocol, and the client heartbeat detection and keep-alive mechanism are added to the MQTT protocol to implement the monitoring function, and then the client online, offline, suspended and other states can be obtained through the monitoring function of the MQTT protocol. In this way, extending the client heartbeat detection and keep-alive on the MQTT protocol can reduce the additional communication channel overhead.

[0022] In one implementation, after the target message to be transmitted is obtained, the method further includes: when there are multiple target messages, performing sequence control on the multiple target messages through the MQTT protocol.

[0023] Specific, for example Figure 2 As shown, the enhanced function can also include a message sequence function. When there are multiple target messages, the multiple target messages can be sequenced and controlled through the MQTT protocol. Through sequence control, the timing of message reading by each client is not affected by factors such as the device time, time zone, network delay, etc. of many clients and servers.

[0024] In one implementation, transmitting the first sub-message to the client via the MQTT protocol includes: The first sub-message is transmitted to the client according to the application scenario of the first sub-message and the service quality guarantee of the MQTT protocol.

[0025] In an embodiment of the present application, the first sub-message can be transmitted to the client according to the application scenario of the first sub-message and the service quality guarantee of the MQTT protocol, and the quality guarantee level of MQTT can be adapted to different message types. The service quality guarantee of the MQTT protocol generally includes: QoS0, QoS1 and QoS2. Among them, QoS0: at most once, when the message is sent to the recipient via the MQTT protocol, the MQTT protocol does not resend the message and confirm the message reception, and provides the same communication guarantee as the TCP / IP protocol. QoS1: at least once, when the message is sent to the recipient via the MQTT protocol, the MQTT protocol guarantees that the recipient receives the message, providing a higher communication guarantee than the TCP / IP protocol. QoS2: only once, when the message is sent to the recipient via the MQTT protocol, the MQTT protocol guarantees that the recipient receives the message and will not receive duplicate information, providing a higher communication guarantee than the TCP / IP protocol.

[0026] In one implementation, the transmitting the first sub-message to the client according to the service quality guarantee corresponding to the application scenario of the first sub-message includes: when the application scenario of the first sub-message is single chat or group chat and the first sub-message is a text message or a link, the first sub-message is transmitted to the client only once through the MQTT protocol; when the application scenario of the first sub-message is group chat and the first sub-message is a read mark message or a group management message, the first sub-message is transmitted to the client at least once through the MQTT protocol; when the application scenario of the first sub-message is an announcement or a system prompt, the first sub-message is transmitted to the client at least once through the MQTT protocol; when the application scenario of the first sub-message is a message notification, the first sub-message is transmitted to the client at most once through the MQTT protocol.

[0027] Specifically, as follows Figure 4 The service quality guarantee distribution shown, where, when the application scenario of the first sub-message is single chat or group chat and the first sub-message is a text message, the service quality guarantee of QoS2 is matched for the data transmission, that is, the first sub-message is transmitted to the client only once through the MQTT protocol. When the application scenario of the first sub-message is single chat or group chat and the first sub-message is a link message of a file, audio, video or picture, the service quality guarantee of QoS2 is matched for the data transmission, that is, the first sub-message is transmitted to the client only once through the MQTT protocol. When the application scenario of the second sub-message is single chat, the second sub-message is transmitted through the HTTP protocol.

[0028] like Figure 4 As shown, when the application scenario of the first sub-message is group chat and the first sub-message is a read mark message or a group management message, the service quality guarantee of QoS1 is matched for the data transmission, that is, the first sub-message is transmitted to the client through the MQTT protocol at least once.

[0029] like Figure 4 As shown, when the application scenario of the first sub-message is an announcement (group announcement, system announcement) or a system prompt, the service quality guarantee of QoS1 is matched for the data transmission, that is, the first sub-message is transmitted to the client through the MQTT protocol at least once.

[0030] like Figure 4 As shown, when the application scenario of the first sub-message is message notification, the service quality guarantee of QoS0 is matched for the data transmission, that is, the first sub-message is transmitted to the client at most once through the MQTT protocol.

[0031] QoS0, QoS1, and QoS2 data receiving / sending service quality assurance are provided for message transmission, and are graded and applied to scenarios such as announcements, reminders, single chat messages, group messages, and file messages. On the basis of ensuring the overall quality service level of instant messaging, the system pressure can be effectively reduced. In addition, the service quality assurance adaptation of each scenario can be flexibly adjusted according to the weight of the message scenario and the weight of system resource overhead.

[0032] In one implementation, before transmitting the second sub-message to the client via the HTTP protocol, it also includes: providing secure transmission guarantee service and integrity verification for the second sub-message via the HTTP protocol.

[0033] In the embodiments of the present application, Figure 2 As shown, the enhanced functions also include providing secure transmission guarantee (HTTPS) service and integrity verification for the second message through the HTTP protocol, thereby ensuring the secure transmission of the message, and ensuring the integrity of the message body through the Http protocol and integrity verification mechanism.

[0034] In one implementation, before transmitting the first sub-message to the client through the MQTT protocol, the method further includes: managing the client through a token.

[0035] In the embodiments of the present application, Figure 2 As shown, the enhanced functions also include ensuring the security of the client through token management, which improves the security of message transmission.
