Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
First, it should be understood that for MQTT, MQTT message middleware (Broker) is used to support message communication between a message sender (Publisher) and a message receiver (Subscriber), and the interaction flow between the three is as follows: when the message middleware is in communication connection with both a message sender and a message receiver, the message sender sends a message to the message middleware, the message middleware further sends the message to the message receiver, after the message receiver consumes the message, a response message is fed back to the message middleware, and finally the message middleware removes the message, wherein if the message receiver is offline in the message interaction process, the message middleware clears the conversation between the message receiver and the message sender, can still maintain a certain amount of offline messages for the message receiver depending on the unique client identification of the message receiver and the setting to meet the configuration requirement of the message sender, and further completes the pushing of the message after the message receiver is reconnected, but if in the message interaction process, an operator wants to withdraw a certain offline message stored in the message middleware, only the corresponding withdrawal type message can be sent, and at this time, the offline message is already received by the message receiver when the message receiver reconnects, that is, the confidentiality of withdrawal of the offline message is not high, so a message sending method for improving the confidentiality of withdrawal after sending the offline message at the message sending end is needed.
An embodiment of the present application provides an offline message sending method, which, in a first embodiment of the offline message sending method of the present application, is applied to a message middleware, where the message middleware is in communication connection with a message sending end, and with reference to fig. 1, the offline message sending method includes:
step S10, receiving a request message sent by a message receiving terminal, and establishing a message channel between the message receiving terminal and the message sending terminal under a target theme according to the request message;
in this embodiment, it should be noted that the message sender is a publisher of a message, and may specifically be one or more, the message receiver is a subscriber of a message, and specifically be one or more, the message middleware is configured to implement functions of answering, storing, and retransmitting a message, and specifically may be any one of ActiveMQ, RabbitMQ, Kafka, and rocktmq, where the storage function of the message middleware is configured to maintain a mapping relationship between Topic (message subject) and a message Queue (Queue), the message Queue is a logical area in the message middleware where a message is actually stored, for a many-to-many message subscription mode, messages sent by different message senders are sequentially stored in the message Queue according to a sending order, if different message receivers want to consume related messages in the message Queue, the message senders need to subscribe a subject before receiving the message, and after subscribing the subject, the message receiver can receive all messages under the theme.
Additionally, it should be noted that the target topic is used to characterize a message topic class to which the target message belongs, the topic type of the message topic may specifically be "payment", "bank card", and "name", and the request message is used to establish a message channel for a message receiving end corresponding to the request message, and the message channel is used to characterize a message interaction channel between the message receiving end and the message sending end under a certain topic, for example, assuming that the message sending end is a and the message receiving ends are B, C and D, where both B and C send the request message to the message middleware, the message middleware does not establish the message interaction channel for D, and establishes different message interaction channels for B and C.
As an example, step S10 includes: receiving a request message sent by at least one message receiving terminal, and establishing a message channel of each message receiving terminal and the message sending terminal under a target message theme according to the request message.
The step of receiving a request message sent by a message receiving terminal and establishing a message channel between the message receiving terminal and the message sending terminal under a target theme according to the request message comprises the following steps:
step A10, receiving the communication request message sent by the message receiving terminal, and connecting the message receiving terminal according to the communication request message;
step a20, receiving a target topic subscription message sent by the message receiving end, and establishing a message channel between the message receiving end and the message sending end under a target topic according to the target topic subscription message.
In this embodiment, it should be noted that the communication request information is used to request connection to the message middleware, and the target topic subscription message is used to subscribe a message topic, so as to subsequently receive a message sent by a message sending end under the message topic.
As an example, the steps a10 to a20 include: connecting the message receiving end according to the communication request message sent by the message receiving end; and receiving a target topic subscription message sent by the message receiving terminal, and establishing a message channel between the message receiving terminal and the message sending terminal under a target topic according to the target topic subscription message, wherein the number of the target topic subscription messages can be one or more.
Step S20, if the message receiving end is detected to be in an off-line state, the target message sent by the message sending end to the message receiving end is obtained through the message channel;
in this embodiment, it should be noted that, after the message receiving end is in communication connection with the message middleware, the message middleware may monitor the connection state of the message receiving end in real time, and when the message middleware monitors that the message receiving end is in an offline state, if the message sending end still sends a message to the target topic, the sent offline messages are all stored by the message middleware, so that the target message is an offline message.
As an example, step S20 includes: and if the message receiving ends are monitored to be in an off-line state, acquiring the target message sent to the message receiving ends by the message sending end through the message channels corresponding to the message receiving ends.
Wherein, if it is detected that the message receiving end is in an offline state, the step of acquiring the target message sent by the message sending end to the message receiving end through the message channel includes:
step B10, if it is detected that the message receiving end is in an off-line state, detecting whether the target message exists in the message channel;
and step B20, if yes, acquiring the target message, and storing the target message to a message queue to be sent.
As an example, the steps B10 to B20 include: if all the message receiving ends are detected to be in an off-line state, whether the message sending end sends off-line messages to the message channel is detected; if the message sending end is detected to send an offline message to the message channel, acquiring the offline message, and storing the offline message to a message queue to be sent under the target theme, wherein the message queue to be sent is a queue for storing the offline message in each session stored in a message middleware; if the message sending end is not detected to send the offline message to the message channel, the connection state of each message receiving end is monitored continuously.
Step S30, if the message receiving end is detected to be changed from the off-line state to the on-line state, filtering the target message to obtain the filtered target message;
in this embodiment, it should be noted that the filtering manner may be a manner of controlling whether an offline message is sent to a message receiving end, where the filtered target message includes an offline message that needs to be sent to the message receiving end or an offline message that does not need to be sent to the message receiving end, and in an implementation manner, referring to fig. 2, fig. 2 is a work diagram illustrating filtering in a one-to-many subscription mode, where an offline message filter is used to control whether the offline message is sent to the message receiving end, when a message middleware delivers a message sent by a message sender to a message receiver, the message receiver sends a response message to the message middleware, so that the message middleware deletes a consumed message corresponding to the response message from a message queue to be sent, and if the message middleware does not receive the response message sent by the message receiver, after the message middleware comes online again, and the message middleware sends the filtered offline message.
As an example, step S30 includes: when the message receiving end is detected to be online again, filtering the offline message to obtain an offline message which needs to be sent to the message receiving end, an offline message which does not need to be sent to the message receiving end or an offline message which needs to be sent to the message receiving end and a message set of the offline message which does not need to be sent to the message receiving end, wherein the message set is generated when a plurality of offline messages are available, and when one offline message is available, the offline message is not the offline message which needs to be sent to the message receiving end, and is the offline message which does not need to be sent to the message receiving end.
The step of filtering the target message to obtain the filtered target message comprises:
step C10, judging whether the first attribute to be filtered of the target message is consistent with the rule attribute of the preset first filtering rule;
step C20, if yes, using the filtered target message as the message to be withdrawn;
and step C30, if not, taking the filtered target message as the message to be sent.
In this embodiment, it should be noted that the preset first filtering rule is a single filtering rule, and the first filtering rule may be preset by a user and may be a specific message topic or a message keyword, and in an implementable manner, the preset first filtering rule may be set in the message filter, for example, if an operator wants to withdraw all contents related to a "bank card", the "bank card" may be used as the filtering rule, when the message filter detects that an offline message exists in the message queue to be sent, the message filter takes the offline message as a message to be withdrawn, if the operator only withdraws the offline message with the tail number of "0004", and when the message filter detects the offline message with the tail number of "0004" in the message queue to be sent, the offline message is taken as the message to be withdrawn.
In addition, it should be noted that the message to be revoked is used for characterizing the confidential messages that the operator needs to revoke or cancel the sending, the message to be sent is used for representing the non-confidential message which needs to be normally sent to the message receiving end by an operator, in one possible implementation, referring to fig. 3, fig. 3 is a schematic diagram illustrating a message middleware process, wherein, the filtering rule 1 and the filtering rule 2 are both first filtering rules, when the message receiving end, the first attribute to be filtered is used for representing the message body of the offline message, the rule attribute of the first filter rule is used for characterizing the specific content of the first filter rule, for example, assuming that the rule attribute of the first filtering rule is "42004", and the first to-be-filtered attribute includes "42004", "42003", and "check-up", the message filter treats only "42004" as the to-be-revoked message.
As an example, the step C10 to the step C30 include: judging whether the message body of the offline message is consistent with the specific content of the first filtering rule or not; if the message body of the offline message is consistent with the specific content of the first filtering rule, taking the filtered offline message as a confidential message needing to be withdrawn or cancelled; and if the message body of the offline message is not consistent with the specific content of the first filtering rule, taking the filtered offline message as an insecure message which needs to be normally sent to the message receiving end.
Step S40, determining whether to send the filtered target message to the message receiving end by judging whether the filtered target message has a message to be sent.
As an example, step S40 includes: and determining whether to send the filtered offline message to the message receiving end by judging whether the filtered offline message contains the message to be sent, wherein the message to be sent is the offline message to be sent to the message receiving end.
The step of determining whether to send the filtered target message to the message receiving end by judging whether the filtered target message has a message to be sent includes:
step D10, judging whether the filtered target message has a message to be sent;
step D20, if yes, sending the message to be sent to the message receiving end;
and D30, if not, deleting the filtered target message.
As an example, the steps D10 to D30 include: judging whether the filtered off-line messages have messages to be sent or not; if the filtered off-line message has a message to be sent, sending the message to be sent to the message receiving end; and if the filtered off-line message has no message to be sent, taking the filtered off-line message as the off-line message which is not needed to be sent to the message receiving end, and directly deleting the off-line message.
Wherein the step of sending the message to be sent to the message receiving end comprises:
step E10, obtaining the message level type between the message sending end and the message receiving end;
step E20, if the message level type is the first type message level, continuously sending the filtered message to be sent to the message receiving end;
step E30, if the message level type is the second type message level, judging whether the filtered message to be sent is repeated;
step E40, if yes, integrating the filtered messages to be sent and sending the integrated messages to the message receiving end;
and E50, if not, sending the filtered message to be sent to the message receiving end.
In this embodiment, it should be noted that, under the mechanism constructed by MQTT, three different levels of QoS (Quality of message) are provided, that is, three different types of message levels, that is, QoS0 "at most once", QoS1 "at least once", and QoS2 "only once", where "at most once" is specifically that when a Publisher (message Publisher) sends a message to a Subscriber (message Subscriber) through a Broker (message middleware), the message middleware does not do any processing, and "at least once" is specifically that when a Publisher (message Publisher) sends a message to a Subscriber (message Subscriber) through a Broker (message middleware), the message middleware copies the message to be sent to the message Subscriber, "once" is specifically that when the Publisher (message Publisher) sends a message to a Subscriber (message middleware) through a Broker (message middleware), the message middleware ensures that a message is sent to the message subscriber.
Additionally, it should be noted that the message level types include an "at least once" message level and an "guaranteed once" message level, the first type message level is an "at least once" message level, and the second type message level is an "guaranteed once" message level.
As an example, the steps E10 to E50 include: acquiring the message level type between the message sending end and the message receiving end from the fixed head of the offline message; if the message level type is the 'at least one time' message level, continuously sending the filtered message to be sent to the message receiving end; if the message level type is a 'one-time guaranteed' message level, inquiring the number of the offline messages in the message queue to be sent; if the number of the off-line messages is multiple, one of the multiple same off-line messages is sent to the message receiving end; and if the number of the offline messages is one, directly sending the offline messages to the message receiving end.
The embodiment of the application provides an offline message sending method, which is applied to a message middleware, wherein the message middleware is in communication connection with a message sending end, namely, receives a request message sent by a message receiving end, and establishes a message channel of the message receiving end and the message sending end under a target theme according to the request message, so that the message sending end and the message receiving end can perform message interaction under the target theme through the message channel of the message middleware; if the message receiving end is detected to be in an off-line state, acquiring a target message sent to the message receiving end by the message sending end through the message channel, namely acquiring an off-line message; if the message receiving end is detected to be converted from the offline state to the online state, filtering the target message to obtain a filtered target message; and determining whether to send the filtered target message to the message receiving end by judging whether the filtered target message has a message to be sent. Because the operator is preset with a filtering rule in the message filter, the offline message in the message middleware can be further filtered, the purpose of controlling whether the offline message is sent to the message receiving end or not through the message middleware is realized, and further, if the filtered message does not have the message to be sent, the filtered message can be controlled in the message middleware, so that the offline message is withdrawn before reaching the message receiving end, instead of sending a withdrawal type message to the message receiving end, and then the offline withdrawal is finished from the business level, that is, the technical defect that the offline message is easy to leak because a post-processing mode is adopted in the prior art is overcome, and the confidentiality of the withdrawal of the offline message is improved.
Example two
Further, referring to fig. 4, in another embodiment of the present application, the same or similar contents as those in the first embodiment may refer to the above description, and are not repeated herein. On this basis, the preset filtering rule includes a filtering chain, the filtered target message includes a message to be sent and a message to be withdrawn, and the step of filtering the target message to obtain the filtered target message includes:
step F10, acquiring a preset number of second filtering rules in a preset filtering chain;
step F20, detecting whether a target filtering attribute exists in the second attributes to be filtered of the target message according to the rule attributes of each second filtering rule;
step F30, if yes, generating a filtering termination command, and using the filtered target message as the message to be withdrawn;
step F40, if not, taking the filtered target message as the message to be sent.
In this embodiment, it should be noted that the preset filter chain includes a plurality of second filter rules, where the second filter rule is a single filter rule in the filter chain, and may specifically be the first filter rule or another filter rule set by a user, and the target filter rule is used to characterize specific contents of the offline message that the operator wants to withdraw.
Additionally, it should be noted that the preset filter chain may be disposed in the message filter, when the preset filter chain is included in the message filter, a plurality of second filter rules in the filter chain may be simultaneously validated, meanwhile, the message filter will sequentially execute filtering according to the serial numbers of different second filtering rules on the filtering chain, and the filter chain is transitive, for example, assuming that the filter chain includes second filter rules a, b, and c, and a, b, and c are sequentially arranged in the message filter, when the target message enters a filtering chain of a preset message filter, filtering by a second filtering rule a to obtain the target message after the first filtering, and then filtering the target message after the first filtering by a second filtering rule b to obtain a target message after the second filtering, and repeating the steps to obtain a final filtered target message.
In an implementation manner, referring to fig. 5, fig. 5 is a schematic diagram illustrating a preset filter chain, where after an offline message enters the schematic diagram of the preset filter chain, the second filter rule may be selected to be executed in sequence, or the execution of the preset filter chain may be terminated in advance, that is, after the second filter rule of the preset filter chain passes through, and at the same time, the message may be directly transmitted to the next filter rule without modifying the processing result of the preset filter chain.
As an example, steps F10 to F40 include: acquiring a preset number of second filtering rules in a preset filtering chain; comparing the message body of the offline message with the specific content of each second filtering rule, and detecting whether the specific content of each second filtering rule has the message body of the offline message; if the specific content of each second filtering rule has a message body of the offline message, generating a filtering termination command, and taking the filtered target message as the message to be withdrawn; and if the specific content of each second filtering rule does not have a message body of the offline message, taking the filtered target message as the message to be sent.
The embodiment of the application provides an offline message filtering method, namely, acquiring a preset number of second filtering rules in a preset filtering chain; detecting whether a target filtering attribute exists in second attributes to be filtered of the target message or not according to the rule attributes of the second filtering rules; if yes, generating a filtering termination command, and taking the filtered target message as the message to be withdrawn; and if the target message does not exist, taking the filtered target message as the message to be sent. Compared with a mode of filtering the offline message only through a single filtering rule, the method can comprehensively filter the offline message sent by the operator through managing the filtering chains of a plurality of filtering rules, and further can withdraw the offline message at one time through the preset filtering chain when the operator needs to withdraw different message bodies of the sent offline message, so that the flexibility of filtering the offline message is improved.
