[0031] Combination Figure 1As shown, the embodiment of the present disclosure provides a message subscription method based on the Netty framework, including:

[0032] Step S101, obtaining the message client and message server corresponding to the target topic;

[0033] Step S102, establishing a message push center between the message client and the message server;

[0034] Among them, the message push center includes Netty server and message queue middleware;

[0035] Step S103, establishing a message push channel corresponding to the target topic between the message client and the Netty server, and sending a topic message request corresponding to the target topic to the message server, so that the message server sends the topic message corresponding to the target topic to the message queue middleware;

[0036] Step S104, using the message queue middleware to send the message queue carrying the subject message to the Netty server, so that the Netty server pushes the subject message to the message client through the message push channel.

[0037] The message subscription method based on the Netty framework provided by the embodiment of the present disclosure is adopted, by establishing a message push center between the message client and the message server, and through the topic message request, the message server sends the topic message corresponding to the target topic to the message queue middleware, and then uses the message queue middleware to send the message queue carrying the topic message to the Netty server, and then pushes the topic message to the message client through the message push channel. In this way, compared with the system transmitting data through respective data transmission channels, the data transmission method between the message client and the message server is unified through the message push center, which reduces the coupling degree of the system in data transmission, thereby reducing the development cost of the access service, and reducing the number of data transmission channels and the channel maintenance cost.

[0038] In some embodiments, the Netty server is built on JAVA NIO (non-blocking IO, non-blocking input / output), which is an asynchronous, event-driven (i.e., Netty will respond to client connection requests, read, write and other events) network application framework with high performance and high concurrency. It is used to develop network IO (input / output) programs based on TCP (Transmission Control Protocol, Transmission Control Protocol) protocol, and also supports UDP (User Datagram Protocol, User Datagram Protocol), HTTP (Hyper Text Transfer Protocol, Hypertext Transfer Protocol), WebSocket (full-duplex communication protocol based on TCP) and other mainstream protocols. Among them, the scalable event model provided by Netty is convenient for adding custom business logic, and the general communication API (Application Programming Interface) provided by Netty is used to simplify the cumbersome code of JAVA NIO.

[0039] In some embodiments, the Netty server supports zero-copy function, so that Netty's receiving and sending ByteBuffer (byte buffer) adopts DIRECTBUFFERS (memory recycling mechanism), and uses off-heap direct memory for Socket reading and writing, without the need for a second copy of the byte buffer. If the traditional heap memory (HEAPBUFFERS) is used for Socket reading and writing, the JVM will copy the heap memory Buffer (buffer class) to the direct memory before writing it to the Socket. Compared with off-heap direct memory, the message has one more memory copy of the buffer during the sending process. Netty provides a combined Buffer object that can aggregate multiple ByteBuffer objects. Users can operate the combined Buffer as easily as operating a Buffer, avoiding the traditional memory copy method of merging several small Buffers into a large Buffer. Netty's file transfer uses the Transfer To method, which can directly send the data of the file buffer to the target channel, avoiding the memory copy problem caused by the traditional circular writing method, thereby improving the transmission efficiency.

[0040] Optionally, a message push channel corresponding to the target topic is established between the message client and the Netty server, including: obtaining the topic type corresponding to the target topic, wherein the topic type includes a public topic or a private topic; establishing a communication connection between the message client and the Netty server, so that the Netty server generates a connection identifier corresponding to the communication connection; if the topic type includes a public topic, a channel cache request carrying the connection identifier and the target topic is sent to the Netty server, so that the Netty server uses the communication connection corresponding to the connection identifier as the message push channel corresponding to the target topic, and caches the message push channel; if the topic type includes a private topic, an access signature corresponding to the target topic is applied to the message server, and a channel cache request carrying the connection identifier, the target topic and the access signature is sent to the Netty server, so that the Netty server performs signature verification on the access signature according to a preset verification key, and after the signature verification passes, uses the communication connection corresponding to the connection identifier as the message push channel corresponding to the target topic, and caches the message push channel.

[0041] Optionally, a message client corresponding to the target topic is obtained in the following manner: a Web (World Wide Web) client is obtained, the Web client includes a client tool module, a target topic and a message consumption application corresponding to the target topic, wherein the client tool module is used to establish a message push channel corresponding to the target topic between the message client and the Netty server; a message client corresponding to the target topic is established, wherein the target topic and the message consumption application are passed into the message client; if the topic type includes a private topic, a preset authentication interface address is passed into the message client, wherein the authentication interface address is located on the message server side.

[0042] In some embodiments, the client tool module is set up through SDK (Software Development Kit).

[0043] Optionally, applying for an access signature corresponding to the target topic from the message server includes: obtaining an identity authentication token, wherein the identity authentication token is used to represent the Web client; using the client tool module to send the identity authentication token, the connection identifier and the target topic to the authentication interface address of the message server, so that the message server performs identity authentication based on the identity authentication token, and after the identity authentication is passed, encrypting at least one of the identity authentication token, the connection identifier and the target topic according to a preset encryption private key to obtain an access signature corresponding to the target topic; receiving the access signature fed back by the authentication interface address.

[0044] In this way, if the topic type subscribed by the message client is a private topic, the message client first applies to the message server for the access signature corresponding to the target topic, and then makes the Netty server perform signature verification on the access signature according to the preset verification key, and caches the message push channel after the signature verification passes, thereby realizing data transmission. Among them, the topic types are divided into public topics and private topics, which improves the flexibility and security of topic subscription.

[0045] In some embodiments, the message server is provided with Redis (Remote Dictionary Server), and a preset encryption private key and a preset encryption public key are stored through Redis.

[0046] Optionally, the message server sends the topic message corresponding to the target topic to the message queue middleware in the following manner: the message server is provided with a server-side tool module, and the message push center also includes a push service; the server-side tool module is used to compress the topic message corresponding to the target topic to obtain an information summary, and the information summary is encrypted according to a preset encryption private key to obtain a push signature corresponding to the topic message, and the push signature and the topic message are sent to the push service; the push service is used to perform signature verification on the push signature based on a preset encryption public key, and the topic message is pushed to the message queue middleware after the signature verification passes.

[0047] In some embodiments, the server-side tool module is set up through the SDK.

[0048] Optionally, after establishing a message push center between the message client and the message server, the method also includes: obtaining the number of topics of the target topic; if the number of topics is less than a preset number threshold, using the preset minimum number as the number of servers of the Netty server; if the number of topics is greater than or equal to the preset number threshold, using the number of topics as the number of servers of the Netty server, wherein there is a one-to-one correspondence between the target topic, the Netty server, and the message push channel.

[0049] In this way, a corresponding number of Netty servers are provided according to the number of target topics, thereby improving data transmission efficiency. At the same time, when the number of target topics decreases, the corresponding number of Netty servers is reduced to reduce transmission costs.

[0050] Optionally, after establishing a message push center between the message client and the message server, the method also includes: performing a heartbeat detection on the Netty server to obtain a heartbeat detection result, and monitoring the subscription status of the target topic; if the first cleaning condition or the second cleaning condition is met, cleaning the message push channel between the message client and the Netty server, wherein the first cleaning condition includes that the heartbeat detection result includes a heartbeat timeout, and the second cleaning condition includes that the subscription status monitored includes unsubscribed.

[0051] In some embodiments, heartbeat detection includes the client and the server periodically sending data packets to each other in the TCP long connection, which can ensure the correct operation of the service and the reliability of the service online and the TCP long connection; the usual heartbeat implementation mechanism is that the client periodically sends data packets to the server, and the server responds after receiving the data, thus ensuring the TCP long connection. If the client does not respond, the corresponding connection is closed to save resources.

In this way, compared with the system transmitting data through respective data transmission channels, the data transmission method between the message client and the message server is unified through the message push center, which reduces the coupling degree of the system in data transmission, thereby reducing the development cost of the access service, and reducing the number of data transmission channels and the channel maintenance cost.
