[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only 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 making creative work are within the scope of protection of the present application.

[0035] Before starting to introduce the technical solutions provided by the embodiments of the present application in detail, several technical concepts involved in the present application are briefly explained as follows.

[0036] A message bus is a communication architecture used to transmit messages between distributed systems or different components. It provides an intermediary layer so that the components of the system can communicate through the publication and subscription of messages without the need for direct interaction.

[0037] Microservice architecture is a method of splitting a large monolithic application into a set of small, independent services. Each service runs in its own independent process, and the services communicate with each other through lightweight communication mechanisms.

[0038] During the research process, the inventors found that in a microservice architecture, a message bus is usually used to transmit data between microservices. For the message publisher, the data transmission process is uncontrollable, and the message publisher cannot direct the message to the designated target message receiver, resulting in the security of data transmission cannot be guaranteed.

[0039] To improve this problem, the embodiment of the present application provides a solution, the basic idea of ​​which is to modify the structure of the target message transmitted between the message publisher and the target message receiver, add a control payload on the basis of the message payload, and the control payload contains an executable script for selecting the target message receiver from the topic subscribers corresponding to the topic identifier for the message payload. The message publisher can specify the target message receiver for the target message through the control payload, so that only the target message receiver can obtain the message payload in the target message, avoiding the leakage of the message payload, thereby improving the security of data transmission.

[0040] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0041] Figure 1 The following is a schematic diagram of a data transmission system provided by an exemplary embodiment of the present application. Figure 1As shown, the system includes: a message publisher 10, a topic subscriber 20 and a message bus 30. The message publisher 10 and the topic subscriber 20 communicate with each other through the message bus 30. The message publisher 10 is the generator of the message and is responsible for sending the message to the message bus 30. The message publisher 10 can be a microservice in a microservice architecture, a service in a distributed system, or a device in an Internet of Things system. The topic subscriber 20 is the receiver of the message and obtains the message from the message bus 30 for processing. The topic subscriber 20 can be a microservice in a microservice architecture, a service in a distributed system, or a device in an Internet of Things system. The message bus 30 can be understood as an intermediary layer, which is responsible for receiving, routing and delivering messages to ensure that the message can be correctly delivered from the message publisher 10 to the topic subscriber 20. The message bus 30 itself is not a device or node with execution capabilities. It only provides a message transmission, routing and distribution mechanism. The actual execution of the message (such as calling a script, processing data, etc.) is completed by the message sending and receiving device or control node included therein. The message sending and receiving device or control node can be any system component that can receive and process messages. It can execute business logic related to the message and even trigger script execution. The technology used by the message bus 30 can be Apache Kafka, RabbitMQ, NATS, ActiveMQ, etc.

[0042] Among them, Apache Kafka is a distributed stream processing platform that is widely used for high-throughput messaging and log collection. RabbitMQ is a message queue middleware that supports multiple messaging protocols and is often used for asynchronous messaging. NATS is a lightweight message queue system that focuses on high-performance and low-latency messaging. ActiveMQ is an open source message queue implementation that supports various messaging protocols.

[0043] In practical applications, the number of accessible message publishers 10 in the data transmission system may be one or more, and the number of accessible topic subscribers 20 in the data transmission system may also be one or more. Figure 1 Only one message publisher 10 and one topic subscriber 20 are shown as an example, but this should not cause loss of the protection scope of the present application.

[0044] The data transmission system provided in this embodiment can be applied to various scenarios that need to rely on a message bus for data transmission, for example, different microservices in a microservice architecture can communicate through a message bus, multiple services in a distributed system can communicate through a message bus, and different business systems under an enterprise can communicate with each other and share data through a message bus, etc. Of course, these are only exemplary, and this embodiment does not limit the application scenarios.

[0045] In this embodiment, the message publisher 10 can construct a message payload based on the data to be transmitted and the subject identifier corresponding to the data to be transmitted. The data to be transmitted refers to the data that the message publisher 10 expects to share with the target message recipient, which usually refers to actual business data or event information. The data to be transmitted depends on the business logic and application scenario. The subject identifier corresponding to the data to be transmitted can be used to characterize the content type of the data to be transmitted.

[0046] In a messaging system, a topic is a classification identifier or label for a message, which is usually associated with the content type, event type, or business domain of the message. Topics provide a mechanism for message publishers and message receivers to accurately route messages to interested message receivers based on their topics. Message receivers can choose to subscribe to a topic and become topic subscribers, and topic subscribers can request access to messages related to the topic.

[0047] On this basis, the data to be transmitted and the subject identifier can be encapsulated to obtain the message payload. In computer networks or communication protocols, the message payload refers to the actual data or content carried in the message, usually the specific information that is expected to be transmitted in the message transmission. The payload is a part of the message, which contains valid information at the application layer or business layer, but does not include header information, tail information or other metadata (such as message header information, routing information, metadata, etc.) used for message transmission.

[0048] After constructing the message payload, the message publisher 10 can generate a control payload for the message payload, and the control payload includes an executable script for selecting a target message recipient from the topic subscribers corresponding to the topic identifier for the message payload. An executable script refers to a script file that can be directly executed by a computer. It contains a series of commands or instructions written according to the rules of a specific programming language. Such an executable script usually does not need to be compiled and can be directly run through an interpreter or a virtual machine. Accordingly, the control payload may also include an interpreter corresponding to the programming language of the executable script, so that the message bus 30 or the topic subscriber 20 can execute the executable script through the interpreter. For example, a Python script requires a Python interpreter to execute, and a Shell script requires a Bash interpreter to execute.

[0049] It can be understood that the executable script in the control payload is configured by the message publisher 10 according to the target information recipient that the message publisher actually wants to communicate with. The logic code in the executable script is the screening condition set for the target information recipient. The purpose is to execute this executable script and use the screening condition in the executable script to determine whether the current topic subscriber is the target message recipient.

[0050] Based on this, the message payload and the control payload can be encapsulated into a target message. The target message may include a message header, a message body, and message attributes. The message body is the core part of the target message and is used to carry the main data during the transmission process. The message body in the traditional target message only contains the message payload. This embodiment encapsulates the message payload and the control payload into the message body, and adds a control payload to the message body. The control payload can be understood as the access permission configured for the message payload. Only the topic subscribers with access permission can access the message payload.

[0051] Among them, encapsulating the control payload into the message body is achieved through various layers of the network protocol stack. Each layer will combine the control payload with the necessary control information according to the requirements of the protocol. In this way, the control payload can be smoothly transmitted in a complex environment through a series of encapsulation processes, and the reliability and integrity of the transmission can be guaranteed. Control information is usually related to the protocol layer. The physical layer is responsible for the physical transmission of data and usually does not involve specific data control information. The control information of the data link layer includes but is not limited to MAC addresses, error detection codes, frame types, etc. The control information of the network layer includes but is not limited to IP addresses, protocol fields, etc. The control information of the transport layer includes but is not limited to port numbers, sequence numbers, confirmation numbers, flags, window sizes, checksums, etc. The control information of the application layer includes but is not limited to the header information of the application protocol, metadata, etc.

[0052] In addition, the message header contains metadata about the target message, which helps the message bus identify, route and process messages. The message header includes but is not limited to message ID, timestamp, sender information, message format, etc. Message attributes are additional information of the target message. Different from the metadata in the message header, they are usually attributes related to message processing. Message attributes may include routing information, expiration time, persistence flag, etc. The target message may also contain a message signature to verify the integrity and source of the target message, which helps to ensure that the target message has not been tampered with during transmission.

[0053] After the message publisher 10 generates the target message, it can send the target message to the message bus so that the message bus can send the target message to the target message receiver. After receiving the target message, the message bus 30 can store the target message in the message queue corresponding to the subject identifier according to the subject identifier carried in the target message. The target message in the message queue can be requested by the subject subscriber corresponding to the subject identifier. The number of subject subscribers can be one or more. Although each subject subscriber can request the message bus to obtain the target message, only the subject subscriber who successfully obtains the message payload in the target message is the target message receiver.

[0054] In this embodiment, the target message recipient may be determined by the message bus or the topic subscriber. For example, the target message recipient may be determined by the message bus from the topic subscriber by running the executable script, or may be determined by the topic subscriber according to the execution status of the executable script after receiving the target message.

[0055] In one case, if the target message receiver is determined by the message bus, the message bus may determine the target message receiver from the topic subscribers by running an executable script.

[0056] For the message bus 30, it can receive the target message published by the message publisher 10. The target message includes a message payload and a control payload. The message payload includes a topic identifier, and the control payload includes an executable script for selecting a target message recipient from the topic subscribers corresponding to the topic identifier for the message payload.

[0057] When the message bus 30 receives a message acquisition request sent by a topic subscriber corresponding to the topic identifier, the target message can be determined according to the topic identifier carried in the message acquisition request. The number of determined target messages can be one or more. The message bus has the same processing logic for each target message. The following takes any target information as an example to introduce the processing logic of the message bus for the target information.

[0058] The message bus can parse the control payload from the target message, and use the configuration information carried in the message acquisition request as the input of the executable script to execute the executable script in the control payload. If the executable script is successfully executed, the topic subscriber can be used as the target message receiver, and the target message is provided to the target message receiver so that the target message receiver can parse the message payload from the target message. If the executable script fails to execute, it can be determined that the topic subscriber is not the target message receiver, and the target message is refused to be sent to the topic subscriber.

[0059] In this embodiment, for the message bus, on the basis of the publish-subscribe mode, an identity authentication link is added. The message bus can authenticate the topic subscriber who initiates the message acquisition request based on the control payload in the target message to verify whether the topic subscriber is the target message recipient specified by the message publisher. Only if the verification is successful will the target message be fed back to the topic subscriber who initiates the message acquisition request. This can achieve the purpose of the message publisher to control the target message recipient in a targeted manner and avoid leaking the target message to irrelevant topic subscribers, thereby effectively improving the security of data transmission.

[0060] In this optional implementation, the executable script may include selection conditions for selecting the target message recipient. The target message bus 30 may use the configuration information carried in the message acquisition request as the input of the executable script, and execute the executable script to determine whether the configuration information meets the selection conditions. Among them, the configuration information carried in the message acquisition request may include the environment information to which the topic subscriber belongs, the version information to which the topic subscriber belongs, the cluster information to which the topic subscriber belongs, and the address information to which the topic subscriber belongs. If the configuration information meets the selection conditions, it can be determined that the executable script is executed successfully. If the configuration information does not meet the selection conditions, it can be determined that the executable script fails to execute.

[0061] It can be understood that the executable script can be a section of code containing judgment logic, and the judgment logic represents the selection conditions for selecting the target message recipient. If the configuration information meets the judgment logic in the code, it is determined that the configuration information meets the selection conditions, and the executable script is executed successfully; if the configuration information does not meet the judgment logic in the code, it is determined that the configuration information does not meet the selection conditions, and the executable script fails to execute. That is, the message bus can respond to the message acquisition request initiated by the topic subscriber and automatically execute the executable script in the target message. By judging whether the configuration information meets the preset selection conditions, it can quickly determine whether the topic subscriber belongs to the preset target message recipient, thereby quickly determining whether to pass the target message to the topic subscriber, which can improve the efficiency of data transmission.

[0062] Of course, other executable script execution schemes may also be used, as long as the target message recipient can be selected, and no further limitations are made here.

[0063] Among them, the executable script can be flexibly configured by the message publisher 10. The following exemplarily shows several executable scripts and the execution logic of the message bus for the executable scripts:

[0064] 1. When the executable script is a logic code for filtering the target message receiver based on the target environment information, the environment information of the topic subscriber can be extracted from the configuration information, and it can be determined whether the environment information belongs to the target environment information. For example, the code in the executable script is: lang: "spel", body: "consumer.env == 'product'". This code limits the target environment information to "product environment". After receiving the message acquisition request sent by the topic subscriber, the environment information of the topic subscriber can be extracted from the message acquisition request. If the extracted environment information is "test environment", it can be determined that the environment information of the topic subscriber does not belong to the target environment information. Therefore, the message bus can determine that the topic subscriber is not the target message receiver and cannot feedback the target message to the topic subscriber.

[0065] 2. When the executable script is a logic code for filtering the target message receiver based on the target version information, the version information of the topic subscriber can be extracted from the configuration information, and it can be determined whether the version information belongs to the target version information. For example, the code in the executable script is: lang: "spel", body: "consumer.version>'1.0.0'". This code limits the target version information to a version higher than 1.0.0. After receiving the message acquisition request sent by the topic subscriber, the version information of the topic subscriber can be extracted from the message acquisition request. If the extracted environment information is version 1.0.0, it can be determined that the version information of the topic subscriber does not belong to the target version information. Therefore, the message bus can determine that the topic subscriber is not the target message receiver and cannot feedback the target message to the topic subscriber.

[0066] 3. When the executable script is a logic code for filtering the target message receiver based on the target cluster information, the cluster information to which the topic subscriber belongs can be extracted from the configuration information, and it can be determined whether the cluster information belongs to the target cluster information. For example, the code in the executable script is: lang: "spel", body: "consumer.cluster in ('a', 'b')". This code limits the target cluster information to a and b. After receiving the message acquisition request sent by the topic subscriber, the cluster information to which the topic subscriber belongs can be extracted from the message acquisition request. If the extracted environment information is c, it can be determined that the cluster information to which the topic subscriber belongs does not belong to the target cluster information. Therefore, the message bus can determine that the topic subscriber is not the target message receiver and cannot feedback the target message to the topic subscriber.

[0067] 4. When the executable script is a logic code for filtering the target message receiver based on the target address information, the address information of the topic subscriber can be extracted from the configuration information, and it can be determined whether the address information belongs to the target address information. For example, the code in the executable script is: lang: "spel", body: "consumer.Ip == '10.xxx'". This code limits the target address information to 10.xxx. After receiving the message acquisition request sent by the topic subscriber, the address information of the topic subscriber can be extracted from the message acquisition request. If the extracted address information is 10.aaa, it can be determined that the address information of the topic subscriber does not belong to the target address information. Therefore, the message bus can determine that the topic subscriber is not the target message receiver and cannot feedback the target message to the topic subscriber.

[0068] In another optional implementation, after receiving the target message, the topic subscriber may determine whether it is the target recipient according to the execution status of the executable script.

[0069] For the topic subscriber 20, a message acquisition request can be sent to the message bus, and the message acquisition request includes a topic identifier for retrieving the target information. The target message returned by the message bus is received, and the target message is retrieved by the message bus based on the topic identifier. It should be noted that the message bus can retrieve one or more target information based on the topic identifier. When multiple target messages are retrieved, multiple target information will be returned to the topic subscriber. Since the processing logic of each target information is the same, the following takes any target information as an example to introduce the processing logic of the topic subscriber for the target information.

[0070] After receiving the target message, the topic subscriber can parse the control payload from the target message. If the control payload cannot be parsed from the target message, the target message is discarded; if the control payload is parsed from the target message, the executable script in the control payload is executed based on the configuration information of the topic subscriber itself. Based on this, if the executable script is executed successfully, it can be determined as the recipient of the target message and the message payload can be parsed from the target message; if the executable script fails to execute, it is determined that it is not the recipient of the target message and the target message is discarded.

[0071] In this embodiment, for topic subscribers, they can no longer directly obtain all messages under the topic they subscribe to as in the traditional solution, but two layers of identity authentication are added: "parsing" and "execution". After receiving the target information, only when the control payload is successfully parsed and the executable script in the control payload is successfully executed, can the identity authentication preset by the message publisher be passed, and the message payload can be successfully parsed from the target message. This can achieve the purpose of the message publisher specifying the target message recipient, avoid leaking the target message to irrelevant topic subscribers, and effectively improve the security of data transmission.

[0072] In this optional implementation, the executable script may also include selection conditions for selecting the target message recipient. The topic subscriber 20 may use the configuration information as the input of the executable script and execute the executable script to determine whether the configuration information meets the selection conditions. If the configuration information meets the selection conditions, it can be determined that the executable script is executed successfully; if the configuration information does not meet the selection conditions, it can be determined that the executable script fails to execute. As described above, by determining whether the configuration information meets the preset selection conditions, it can be quickly determined whether it belongs to the preset target message recipient, thereby deciding to retain or discard the target message, thereby improving the efficiency of data transmission.

[0073] Of course, other executable script execution schemes may also be used, as long as the target message recipient can be selected, and no further limitations are made here.

[0074] Among them, the executable script can be flexibly configured by the message publisher 10. The following exemplarily shows several executable scripts and the execution logic of the topic subscriber for the executable scripts:

[0075] When the executable script is a logic code for filtering the target message recipient based on the target environment information, the environment information to which the subject subscriber belongs can be extracted from the configuration information, and it can be determined whether the environment information belongs to the target environment information. When the executable script is a logic code for filtering the target message recipient based on the target version information, the version information to which the subject subscriber belongs can be extracted from the configuration information, and it can be determined whether the version information belongs to the target version information. When the executable script is a logic code for filtering the target message recipient based on the target cluster information, the cluster information to which the subject subscriber belongs can be extracted from the configuration information, and it can be determined whether the cluster information belongs to the target cluster information. When the executable script is a logic code for filtering the target message recipient based on the target address information, the address information to which the subject subscriber belongs can be extracted from the configuration information, and it can be determined whether the address information belongs to the target address information.

[0076] In summary, in this embodiment, the message publisher can construct a control payload for the message payload, and the control payload contains an executable script for selecting a target message recipient from the topic subscribers corresponding to the topic identifier for the message payload, and encapsulates the message payload and the control payload into a target message and sends it to the message bus, so that the message bus can send the target message to the target message recipient. In this way, the structure of the target message is transformed, and the control payload is added on the basis of the message payload. The message publisher can specify the target message recipient for the target message through the control payload, and the control payload can be used to authenticate the topic subscriber corresponding to the topic identifier in the message payload, so that only the target message recipient can obtain the message payload in the target message, avoiding the leakage of the message payload, thereby improving the security of data transmission.

[0077] In the above or below embodiments, the message publisher 10 may generate a control payload for the message payload in a variety of implementations.

[0078] Optionally, the message publisher 10 may generate an executable script in a target programming language in response to a conditional configuration operation performed on the message payload, and generate a control payload based on the identification information of the target programming language and the executable script. Among them, the executable script may include selection conditions configured by the conditional configuration operation for selecting a target message recipient. The target programming language mentioned here is the programming language selected by the message publisher 10 according to its own environment. The identification information of the target programming language can be used to characterize the language type of the target programming language, and the language type may include but is not limited to JavaScript, Lua, SPEL, Python, etc. The message publisher can flexibly select a suitable target programming language to generate a control payload according to actual needs, which alleviates the execution restrictions caused by the language type and enhances the applicability of the control payload.

[0079] For example, in response to an environment configuration operation performed on a message payload, the target environment information configured by the environment configuration operation for selecting a target message recipient may be determined, and a logic code for filtering the target message recipient based on the target environment information may be written in a target programming language as an executable script. In response to a version configuration operation performed on a message payload, the target version information configured by the version configuration operation for selecting a target message recipient may be determined, and a logic code for filtering the target message recipient based on the target version information may be written in a target programming language as an executable script. In response to a cluster configuration operation performed on a message payload, the target cluster information configured by the cluster configuration operation for selecting a target message recipient may be determined, and a logic code for filtering the target message recipient based on the target cluster information may be written in a target programming language as an executable script. In response to an address configuration operation performed on a message payload, the target address information configured by the address configuration operation for selecting a target message recipient may be determined, and a logic code for filtering the target message recipient based on the target address information may be written in a target programming language as an executable script.

[0080] In summary, in this embodiment, the message publisher can flexibly define the judgment logic inside the executable script according to the actual data transmission requirements. By adjusting the control payload as needed, the message publisher can dynamically specify the target message recipient for any target message, thereby achieving directional delivery of the target message and ensuring the security of data transmission.

[0081] In the above or following embodiments, an associated operation script may also be configured in the control payload. The associated operation script may be used to describe associated operations configured for the message payload. The associated operations include but are not limited to consumption reporting statistics, log reporting, third event triggering, concurrency control, or delay time control.

[0082] The message publisher 10 may obtain the associated operation script configured for the message payload and add the associated operation script to the control payload, so that the target message receiver may run the associated operation script upon receiving the target message to perform associated operations on the message payload.

[0083] For the target message receiver, after receiving the target message, the control payload can be parsed from the target message. If the control payload cannot be parsed from the target message, the target message is discarded. If the control payload is successfully parsed, the associated operation script is parsed from the control payload and the associated operation script is executed to perform the associated operation on the message payload.

[0085] Of course, these are only exemplary, and the associated operations may also include consumption statistics reporting, log reporting, delay time control, etc. No further examples are given here.

[0086] In summary, in this embodiment, by configuring the associated operation script in the control payload, the target message recipient can be provided with additional capabilities associated with the target message, which expands the functions of the target message recipient and further enriches the functions supported by the target message recipient.
