Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that, in the present disclosure, the embodiments and features of the embodiments may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates an exemplary system architecture 100 of a method for message processing or an apparatus for message processing to which embodiments of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The user may use the terminal devices 101, 102, 103 to interact with the server 105 via the network 104 to receive or send messages, etc., for example, a message of the user that the user wants to publish on the message middleware platform may be sent to the server, and a message to be queried by the user may be received from the server.
The terminal apparatuses 101, 102, and 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be electronic devices with communication functions, including but not limited to smart phones, tablet computers, e-book readers, laptop portable computers, desktop computers, and the like. When the terminal apparatuses 101, 102, 103 are software, they can be installed in the electronic apparatuses listed above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
In the disclosed embodiment, the server 105 is a peer node in the blockchain, on which an account book and a preset intelligent contract are stored, and the server implements data interaction with the blockchain through the intelligent contract, for example, issues a message to the blockchain, so that the message is stored in the account book data of all nodes in the blockchain; messages issued by other nodes in the blockchain may also be received. In the embodiment of the present disclosure, the server 105 may perform data interaction with the terminal device through a network, for example, receive a message operation instruction sent by the terminal device, and implement data interaction with the blockchain according to the message operation instruction.
The peer node is a physical concept, and one server can act as the peer. This server can be either a private physical machine or a resource on the cloud. The peer is the infrastructure of the entire blockchain on which critical data is stored and specific programs are executed. The stored data comprises an account book and an intelligent contract, and the executed program mainly comprises endorsement and execution of the intelligent contract. All ledger queries and ledger modifications must be operated by intelligent contracts, and all intelligent contract operations must be invoked by peer nodes, so that SDKs (Software Development kits) or applications must pass peer nodes when they need to access ledger data.
It should be noted that the method for message processing provided by the embodiments of the present disclosure may be executed by the terminal devices 101, 102, and 103, and the apparatus for message processing may be disposed on the terminal devices. For example, the terminal device may be loaded with a message agent module to receive a message operation instruction of a user and send the message operation instruction to a specified server (i.e., peer node), the server is loaded with a block chain SDK, and the server implements data interaction with the block chain through a corresponding intelligent contract according to the received message operation instruction. The method can also be executed by the server 105, at this time, a device for processing the message is arranged in the server 105, and the server 105 is loaded with a message agent module and a block chain SDK, and is used for receiving a message operation instruction of a user, converting the message operation instruction into a corresponding block chain intelligent contract through the block chain SDK, and then realizing data interaction with the block chain by executing the corresponding intelligent contract. The present application is not specifically limited herein.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for message processing in accordance with the present disclosure is shown. The method for message processing comprises the following steps:
In this embodiment, the execution main body may be loaded with a message agent module for receiving a message operation instruction of a user. The message operation instruction is used for characterizing the processing action of the user on the message, and can be a published message or a query message and the like.
In this embodiment, a block chain may be constructed in advance, each peer node in the block chain corresponds to one user, and each peer node stores an account book and a preset intelligent contract, and is used to provide a message service for each user. When a new user is added, only a new peer node needs to be deployed for the new user.
As an example, a company may share a block chain, each department deploys peer nodes of the block chain, and based on an information consensus mechanism between the block chain nodes, messages in an account book stored on each peer node are synchronized, so as to implement publishing and synchronization of messages between each department. Meanwhile, a block chain SDK is deployed on the terminal equipment serving as the peer node, the peer node accesses the block chain constructed in advance according to the block chain SDK, and data interaction is carried out on the block chain according to the received message operation instruction so as to complete the message processing flow.
In a specific example, an execution main body receives a message operation instruction of a user as an instruction for issuing a message, the execution main body sends the instruction for issuing the message to a corresponding peer node, then the peer node accesses a block chain through a block chain SDK, executes an intelligent contract corresponding to the issued message, stores the content of the message to be issued into its own account book, and broadcasts the content to the block chain to synchronously update the account books of other peer nodes, thereby completing "uplink" of the message, that is, completing the issuing of the message.
In another specific example, when a user wants to query messages issued by other users from the blockchain, an instruction of the message to be queried may be input to the execution main body, where the instruction includes characteristic information of the message to be obtained, such as a sender of the message, a global ID of the message, a type of the message, and the like, and then the execution main body sends the instruction of the query message to the corresponding peer node, and after the peer node receives the instruction of the query message, the smart contract corresponding to the obtained data is executed, a message meeting query conditions is retrieved from the ledger, and is sent back to the execution main body, so that the query of the message is completed.
In some optional implementation manners of this embodiment, the message operation instruction includes a message issuing instruction, which is used to instruct the peer node to send the message to be issued to the block chain; the message issuing instruction comprises a message to be issued, a channel identifier, a subject identifier and a message unique identifier, wherein the channel identifier is used for indicating the peer node to send the message to be issued to a channel (channel) corresponding to the channel identifier in the block chain; the topic identification is used for indicating the peer node to send the message to be issued to a topic (topic) corresponding to the topic identification in a channel corresponding to the channel identification; the message unique identification is used for representing the unique identity of the message to be issued in the block chain.
Generally, one peer node can join a plurality of channels in the block chain at the same time, and each channel can be preset with a plurality of themes.
In the implementation manner, by using an isolation mechanism of the channel, isolation of message processing processes of different groups can be achieved, and cooperation among different organizations can be achieved by a plurality of channels. The theme can be preset according to actual requirements so as to carry out classification management and operation on the messages according to the themes of the messages.
As an example, the message sending instruction may consist of a channel name + topic + message ID + message content to be published. After the execution main body sends the message sending instruction to the peer node, the peer node analyzes a channel identifier to be issued, a theme identifier, a message unique identifier and a message to be issued from the message instruction, then determines a channel corresponding to the channel identifier in a block chain based on the channel identifier, determines a theme corresponding to the theme identifier in the channel based on the theme identifier, then executes an intelligent contract corresponding to the issuing information, broadcasts the message to be issued to the corresponding theme in the channel, and completes the issuing process of the message.
In some optional implementations of this embodiment, the message operation instruction includes a message query instruction, which is used to instruct the peer node to acquire and send a message matching the message query instruction from the blockchain.
In the implementation manner, after the execution main body sends the message query instruction to the peer node, the peer node analyzes the query condition of the user from the message query instruction, then executes the intelligent contract corresponding to the acquired data, acquires the message meeting the query condition from the account book, and sends the message back to the execution main body. The query condition may be, for example, a message in a certain channel, a message under a certain subject, or a unique identity of a message.
In some optional implementations of this embodiment, the message operation instruction includes a message subscription instruction, and the message subscription instruction includes a subscription condition, and is used to instruct the peer node to acquire and send a message that satisfies the subscription condition from the blockchain.
In the implementation mode, a user can set subscription conditions according to own requirements, then the execution main body generates a message subscription instruction and sends the message subscription instruction to the peer node, the peer node analyzes the subscription conditions of the user from the message subscription instruction, then executes a corresponding intelligent contract to obtain a message meeting the subscription conditions from the book, and sends the message back to the execution main body. As an example, the subscription condition may be a timing acquisition message or a message to acquire a certain specified channel. In this way, the execution subject can automatically acquire the messages meeting the subscription condition in the blockchain.
According to whether the starting time of the subscription time is the current time or the historical time, the execution subject can acquire the real-time message or the historical message from the block chain through the peer node. If the initial time of the subscription is the current time, the peer node can be further instructed to monitor the messages in the block chain, and when the messages meeting the subscription condition are detected, the messages are automatically sent to the execution main body.
As an example, the message subscription instruction received by the execution main body is to subscribe to a message in a service channel at the current time, the execution main body sends the message subscription instruction to the peer node, the peer node invokes a corresponding intelligent contract, and the message in the channel at the current time in the ledger is sent back to the execution main body. And, the message in the block chain can also be monitored, and when detecting that a new message appears in the channel, the message is automatically sent back to the execution subject.
Further, the message subscription instruction may further include a keyword included in the message to be subscribed, so as to instruct the peer node to acquire a message matching the keyword from the blockchain.
With continued reference to fig. 3, fig. 3 is a schematic illustration of one scenario in which the method of fig. 2 may be applied. In fig. 3, servers 302, 303, 304 and 305 are peer nodes in a blockchain 306, and the execution subject 301 may be a terminal device, and the terminal device 301 is communicatively connected to one of the servers 302 and configured to send a message operation instruction to the server 302. For example, when the execution agent wants to issue the message "a", the instruction "issue the message a" is sent to the server 302, after receiving the instruction, the server 302 sends the message a to the blockchain 306 by executing the node intelligent contract corresponding to the issue message, and then, based on the information consensus mechanism among the nodes, the message "a" is also stored in the ledger of the other peer nodes 303, 304, and 305 in the blockchain, and the issue of the message "a" is completed.
According to the method and the device for message processing, the message operation instruction is sent to the peer node in the block chain to indicate the peer node to perform data interaction with the block chain, the message processing action is completed, decentralized and distributed deployment of the message middleware platform are achieved, and meanwhile, the data security of the framework service can be improved due to the characteristics that the block chain has the advantages of being incapable of being tampered with, traceable, attentive to trust and the like.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for message processing is shown. The flow 400 of the method for message processing includes the following steps:
And 402, sending the message operation instruction to a peer node preset in the block chain constructed in advance. This step is similar to the step 202, and will not be described herein.
In this embodiment, the execution subject may cache the message issued by the user, so as to perform subsequent operations such as analysis and statistics on the message.
In this embodiment, a user may preset a trigger condition and a message generation policy by an execution main body, and when the execution main body detects that a message to be issued in a message issuance set satisfies the preset condition, automatically generate a cache message issuance instruction according to the message generation policy, so as to instruct a peer node to issue a message content corresponding to the cache message issuance instruction to a block chain.
As an example, it may be preset that the content of the message to be published includes a specified keyword, when the execution subject monitors that a message including the keyword appears in the published message set, a cache message publishing instruction "sender identification of the message (for example, a physical address of the sender) + the keyword included in the message" is automatically generated, and then the cache message publishing instruction is sent to the peer node, and the peer node completes a publishing process of the message.
For another example, the user may pre-threshold the number of messages to be published, and when the execution subject detects that the number of messages in the published message set reaches the number threshold, automatically generate a cache message publishing instruction of "the number of published messages in the published message set + the time when the number reaches" and then send the cache message publishing instruction to the peer node, and the peer node completes the publishing process of the message.
It will be appreciated that the execution agent itself may also act as a peer node, in which case the execution agent may cache and monitor all messages sent to the blockchain via the peer node.
And step 405, storing the received message sent by the peer node to a callback message set.
In this embodiment, the callback message set is used for caching the message returned by the peer node so as to facilitate the subsequent callback processing of the part of the message, and the callback message set may include, for example, a message queried by the user and a message subscribed by the user.
In this embodiment, the execution main body may execute a preset instruction on the message cached in the callback message set according to the received callback instruction, for example, the user may set a filtering condition, and filter a message meeting the condition from the callback message set among all messages received by the execution main body. For another example, the user may set an instruction to periodically clear the cache, and when the preset time is reached, the execution subject may automatically clear the message in the callback message set.
As can be seen from fig. 4, the flow 400 of the method for processing a message in this embodiment adds a step of caching a release message and a callback message, and can perform logic processing on the release message by caching and monitoring the release message, thereby implementing message driving; by caching callback messages, further processing of messages retrieved from the blockchain is facilitated.
