Detailed Description
The present invention is further described in the following with reference to the drawings and the specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention, and the embodiments and the technical features of the embodiments can be combined with each other without conflict.
The embodiment of the invention provides a multi-user message pushing method based on a publish-subscribe mode, which is used for solving the technical problem of how to send and receive messages based on the topic of the messages.
Example 1:
as shown in fig. 1 and fig. 2, the multi-user message pushing method based on the publish-subscribe mode of the present invention includes the following steps:
s100, collecting the requirements of the message subscriber by the message publisher, formulating a subscription theme, and setting a personalized message notification format according to the subscription theme;
the message subscribers subscribe or cancel the subscribed topics based on the interests of the message subscribers and generate corresponding topic subscription states, wherein the topic subscription states are used for representing the states of the subscription or the cancellation of each message subscriber to each subscribed topic;
storing a subscription theme, a message notification format and a theme subscription state through a message subscription list;
s200, the message publisher pushes the produced messages to a message queue, the message queue is a distributed message queue, and the message queue stores the received messages to a memory queue of the message queue;
s300, distributing each message based on the content and the theme, and pushing each message to a corresponding message subscriber in cooperation with a message subscription list.
In step S100, the message publisher performs subscription management, collects the requirements of the user (i.e., the message subscriber), formulates a subscription topic for the content with higher access amount or query rate, and the subscriber can subscribe or unsubscribe to a topic in the message channel. The topic enables the subscribers of the message and the publishers of the message to remain independent of each other, and the delivery of the message can be guaranteed without contact.
Meanwhile, the message publisher configures the message, sets a personalized message notification format according to different subscription topics, and specifically comprises the following steps: message content, message type, transmission location, transmission time, message level, etc.
In step S300, after the message queue acquires the message, the message is checked and distributed, and the message is checked and distributed according to the content of each message. Each subscriber may specify content of interest to him. There are two common forms of filtration: theme-based and content-based.
In a topic-based system, messages are published onto a topic or named channel. Subscribers will receive all messages on the topic to which they subscribe, and all subscribers subscribing to the same topic will receive the same message. Publishers are responsible for defining the categories of messages to which subscribers subscribe.
In a content-based system, a subscriber defines the conditions for messages that the subscriber is interested in, and a message is delivered to the subscriber only if the attributes or content of the message satisfy the subscriber-defined conditions. The subscriber needs to be responsible for classifying the messages. The system supports a mix of the two: publishers publish messages to topics and subscribers register content-based subscriptions to one or more topics.
And the message queue is used for storing the messages until the messages are sent to the consumers. It is the container of the message and also the end point of the message. A message may be dropped into one or more queues. The message is always inside the queue waiting for the consumer to connect to the queue and take it away.
Message queues provide a one-step communication protocol, meaning that the sender and recipient of a message do not need to stay in contact with the message at the same time, and the sender's message will be stored in the queue until the recipient picks it up. The sender of a message is generally referred to as the producer and the recipient of the message is referred to as the consumer. Because the producer and the consumer are opaque, they are contacted by a tie-message queue in the middle.
The distributed message queue can be regarded as deploying the data structure to an independent server, and using the distributed message queue through a remote access interface to store messages, so as to realize distributed asynchronous call. Correspondingly, the work flow is as follows:
(1) the message producer application program pushes the message to the message queue server through the remote access interface, and the message queue server writes the message into a local memory queue and immediately returns a successful response to the message producer;
(2) the message queue server searches a consumer application program subscribing the message according to the message subscription list, and sends the message in the message queue to the consumer application program through a remote communication interface according to a first-in first-out principle;
(3) the consumer application receives the pushed message and then performs a related series of processes, and the process is terminated.
In the process of pushing a message to a message queue by a message publisher, firstly, a message producer produces a message and sends the message to a virtual host in a message agent (server), an exchanger and a queue are arranged in the virtual host, the virtual host sends the message to a specified exchanger, and the exchanger judges which message queue the message is routed to according to a routing key of the message, wherein a routing rule is represented by a binding relationship. When the message arrives at the message queue, the consumer can take out the message from the message queue, the consumer establishes connection with the message queue, in order to save resources, a plurality of channels are opened up in each TCP connection, and data is transmitted to the consumer through the channels.
As an improvement, in order to improve the effectiveness of message publishing, before each message is pushed to a corresponding message subscriber, a filtering operation is performed on the message, and the filtering operation includes the following steps:
(1) the messages are sequenced, and the sequence of receiving the messages by the user instance is not necessarily ensured, nor does the sequence reflect the creation sequence of the messages. The method is designed to ensure that message processing is equal in magnitude to help eliminate any dependency on the order of message processing;
(2) the method comprises the steps of carrying out priority configuration on messages, and processing the messages based on a priority queue mode, wherein the priority queue mode provides a mechanism for ensuring that a specific message is transmitted before other messages;
(3) the same message may be sent multiple times based on the ID of the message and the detection and deletion of reverse repeat messages to delete duplicate messages. For example, a sender may have an exception after issuing a message, not recording that it has successfully sent the message, and then a new instance of the sender may initiate and repeat the message, and the message infrastructure should implement duplicate message detection and deletion (also referred to as deduplication) based on the message ID to provide at most one message pass;
(4) carrying out toxic information detection, deleting messages with wrong formats or messages needing to access unavailable resource tasks, and preventing the messages from returning to the queue, wherein otherwise, system faults can be caused;
(5) based on a message lifetime configured by a message subscriber, checking whether the message has expired and deleting the expired message, the message lifetime may be limited, it may no longer be valuable if not processed within this period of time, it should be discarded, the sender may specify the expiration time as part of the data in the message, and the receiver may check this information to ensure that the message has not expired before deciding whether to execute the business logic associated with the message.
In the multi-user message pushing method based on the publish-subscribe mode of the embodiment, the publish/subscribe mode enables distribution of messages to break through the limitation of geographic orientation of a destination queue, so that the messages are distributed according to a specific theme or even content, and users or application programs can receive required messages according to the theme or the content.
The publish/subscribe mode loosens the coupling between the sender and the receiver, and the sender does not need to be concerned about the destination address of the receiver, and the receiver does not need to be concerned about the sending address of the message, but only sends and receives the message according to the subject of the message. The method is convenient for the masses of users to receive the message reminding, so that the related subscription topics need to be configured in advance according to the user requirements for the users to select. The following description takes the subject of applicant subscription 'interpretation of policy and regulation' as an example:
(1) configuring a policy and regulation reading template in the configuration of a subscription theme template;
(2) configuring 'user is your good, the latest policy and regulation is used for reading the message and please click to view' in the message template configuration;
(3) and issuing related policy interpretation information in the subject template configuration of 'policy and regulation interpretation'.
(4) And starting message timing sending configuration in the message sending configuration, and sending a message prompt to the subscriber.
