Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a method for distributing a testament information. Fig. 1 is a schematic flow chart of an advice message distribution method according to an embodiment of the present invention. The method may be performed by an apparatus, which may be implemented by software and/or hardware, and in this embodiment, the apparatus is a server.
In this embodiment, the method for distributing the will order message includes:
s101, connecting a current client based on an mqtt protocol and receiving a testament message of a corresponding specific theme registered by the current client;
s103, sending the testament information to an information middleware after judging that the current client is abnormally disconnected;
s105, distributing the will order message to each distribution server through the message middleware, so that each distribution server can send the will order message to the client matched with the specific theme.
For example, a client accesses the system, the client subscribes to a specific topic, the client registers a testimony message, after the client is abnormally disconnected, the testimony message is sent to a message middleware (such as rocktmq), rocktmq distributes the message to each distribution server of an mqtt protocol cluster, and if the client connected with a certain distribution server matches the specific topic, the distribution server sends the testimony message to the client.
Further, in step 101, the step of connecting the current client includes:
receiving an access authentication request of the current client;
and feeding back an access authentication result to the current client to confirm connection.
In this embodiment, after the access authentication is passed, the current client may subscribe to the related topic, and the topic subscription is performed according to a preset topic format, and if the format of another topic is accessed, an error may be caused, and the subscription fails.
Further, the accessing, such as an authentication request, includes: the system comprises a fixed header, a variable header and a message body, wherein the message body comprises a client ID, a user name and a password.
Further, the access authentication result fed back comprises a fixed header and a variable header, and the variable header comprises a response result. The response result is judged according to the client ID, the user name and the password of the accessed client, if the judgment is legal, the authentication is successful, the client is successfully accessed, and further the communication with the accessed server is realized; after the access is successful, if the client needs to release the message, the server judges whether the released subject name of the Saxifraga is in a preset format or not after receiving the released message, if the server illegally uses other subject names, the server disconnects the connection with the client, and the message is failed to be released; and if the used subject name is legal, the message of the client is successfully issued.
Further, the determining that the current client is abnormally disconnected includes:
when another accessed client and the current client have the same client identifier and DISCONNECT, when the current client accesses other unauthorized subjects and DISCONNECTs, the current client does not receive a DISCONNECT message sent by the current client and closes the network connection and DISCONNECTs, and the current client fails to communicate and DISCONNECTs within the time of keeping the connection, or DISCONNECTs when the connection of the network communication protocol is marked as an inactive state.
Further, the method further comprises: and deleting the advice message when the client is judged to be normally disconnected.
Further, after the step of connecting the current client, the method further comprises:
receiving a subscription subject authentication request sent by the current client;
and feeding back a subscription theme authentication request result to the current client.
In this embodiment, after subscribing to a topic successfully, the current client may PUBLISH a message, and the topic names in the PUBLISH message for publishing the message, the PUBLISH message for replying to the control message, and the PUBLISH message for replying to the query message need to be set by the installation rule, which may result in disconnection if publishing is performed using other topic names.
In this embodiment, based on the Netty framework, a method called channelInactive is called when the connection of the client is disconnected; in the present embodiment, the file storage model of rocktmq includes: the system comprises a business processing layer, a data file storage component layer, a storage logic object layer, a packaged file memory mapping object layer and a disk storage layer.
The beneficial effects of the method for distributing the testimonial advice message provided by the embodiment are as follows: and after the client is judged to be abnormally disconnected, the will-order message is sent to a message middleware, and the will-order message is distributed to each distribution server through the message middleware, so that each distribution server can send the will-order message to the client matched with the specific theme, and the efficiency of the distribution of the will-order message is improved.

The response result is judged according to the client ID, the user name and the password of the accessed client, if the judgment is legal, the authentication is successful, the client is successfully accessed, and further the communication with the accessed server is realized; after the access is successful, if the client needs to release the message, the server judges whether the released subject name of the Saxifraga is in a preset format or not after receiving the released message, if the server illegally uses other subject names, the server disconnects the connection with the client, and the message is failed to be released; and if the used subject name is legal, the message of the client is successfully issued.
Further, the determining that the current client is abnormally disconnected includes:
when another accessed client and the current client have the same client identifier and DISCONNECT, when the current client accesses other unauthorized subjects and DISCONNECTs, the current client does not receive a DISCONNECT message sent by the current client and closes the network connection and DISCONNECTs, and the current client fails to communicate and DISCONNECTs within the time of keeping the connection, or DISCONNECTs when the connection of the network communication protocol is marked as an inactive state.
Further, the processor 13 executes the will information distribution program 111 stored in the memory 11 to further implement the following steps: and deleting the advice message when the client is judged to be normally disconnected.
Further, when the processor 13 executes the will message distribution program 111 stored in the memory 11 after the step of connecting the current client, the following steps are also implemented:
receiving a subscription subject authentication request sent by the current client;
and feeding back a subscription theme authentication request result to the current client.
In this embodiment, after subscribing to a topic successfully, the current client may PUBLISH a message, and the topic names in the PUBLISH message for publishing the message, the PUBLISH message for replying to the control message, and the PUBLISH message for replying to the query message need to be set by the installation rule, which may result in disconnection if publishing is performed using other topic names.
In this embodiment, based on the Netty framework, a method called channelInactive is called when the connection of the client is disconnected; in the present embodiment, the file storage model of rocktmq includes: the system comprises a business processing layer, a data file storage component layer, a storage logic object layer, a packaged file memory mapping object layer and a disk storage layer.
