Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to better understand the technical scheme provided by the application, the technology related to the application is first described.
As shown in FIG. 1, the existing government affair data sharing and exchanging method adopts a tree-shaped cascade structure to carry out information resource directory service and data exchange service, and the system is mainly divided into three levels of nodes of countries, provinces and places, so as to realize data exchange at the levels of countries, provinces, cities and counties. Storing and providing a government information resource general catalog and a national government data exchange service at a national node; storing and providing relevant provincial government information resource catalogs and provincial switching services at provincial nodes; and storing and providing the local market level and below government information resource catalog and local market level and below exchange service at the local market level node. The lower node should use the upper node to register the current government information resource and exchange data across areas.
However, the government data sharing exchange architecture described above has the following disadvantages:
1. the timeliness of the data is not high. The current cross-level data sharing is reported and issued layer by a city sharing exchange platform, a provincial sharing exchange platform and a country sharing exchange platform, and whether the lower level reports to the upper level or the upper level issues data to the lower level, batch operation is required by means of a timing scheduling mechanism, the more the cross-layers are, the longer the link is, and the lower the timeliness of the data is.
2. Data consistency is poor and trace back is difficult. Once a central node (such as a provincial node) fails under the current shared switching system, the communication between the central node and a sub-node (each city) fails, and the sub-node fails, so that configuration data among different nodes is lost, the problem of inconsistent data occurs, meanwhile, the data lacks unique description, and the tracing is difficult when the problem occurs.
In view of the above, the application provides a system and a data acquisition method for sharing and exchanging government affair data based on P2P.
The system and the data acquisition method for sharing and exchanging government affair data based on P2P provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.

The data transmission management and control module 210 is configured to perform unified management on the shared government affair data and the government affair data acquisition request, so as to implement network scheduling on the government affair data; the data exchange network module 220 is configured to process the government affair data acquisition request and government affair data corresponding to the government affair data acquisition request, and implement sharing of the government affair data, where the data exchange network module includes a plurality of network transmission nodes, each network transmission node 221 includes a P2P file system 222, and the P2P file system 222 is configured to store a configuration file corresponding to the shared government affair data; the P2P file system 222 may be composed of a plurality of nodes, and is responsible for storing and distributing files, where each node has the same roles and roles without master-slave division. The city sharing exchange module 230 includes a plurality of sharing exchange nodes for communication between a plurality of service systems and corresponding network transmission nodes, where each sharing exchange node corresponds to one service system and one network transmission node; the service system module 240 includes a plurality of service systems for sharing verification, collection and initiation of a government service data acquisition request.
In an embodiment of the present application, a system for sharing and exchanging government affair data based on P2P is provided, where the system includes: the system comprises a data transmission management and control module, a data exchange network module, a city sharing exchange module and a service system module, wherein the service system module comprises a plurality of service systems, the data exchange network module comprises a plurality of network transmission nodes and P2P file systems corresponding to the network transmission nodes, the city sharing exchange module comprises a plurality of sharing exchange nodes, and each sharing exchange node corresponds to one service system and one network transmission node. In the system, when government affair data sharing interaction is needed, a data transmission management and control module processes government affair data acquisition requests, government affair data acquired by a business system are sent to corresponding network transmission nodes through corresponding sharing exchange nodes, a P2P file system corresponding to the network transmission nodes processes the government affair data to obtain a target configuration file, the target configuration file comprises a configuration data file and a configuration meta file, the configuration data file and the configuration meta file are stored under a preset directory of the P2P file, the network transmission nodes corresponding to a business system initiating the government affair data acquisition requests perform data searching by utilizing hash values of unique configuration data files or configuration meta files, and analyze the acquired government affair data, and the government affair data are transmitted to a data demand business system through the corresponding sharing exchange nodes to finish point-to-point data exchange sharing. Through the point-to-point data sharing exchange mode, interconnection and intercommunication among all network transmission nodes are realized, an upper node is not needed to pass through in the data sharing exchange process, the data transmission time is saved, and the real-time performance of the data sharing exchange is greatly improved.
Based on the foregoing embodiments, in one implementation, the plurality of service systems includes a data demand service system and a target service system, and the plurality of network transmission nodes includes a data demand network transmission node corresponding to the data demand service system and a target network transmission node corresponding to the target service system. It will be appreciated that the data demand service system refers to a party that initiates a government data acquisition request, and the target service system refers to a party that provides government data based on the government data acquisition request. Further, as shown in fig. 3, the plurality of service systems include a provincial system and a plurality of local market systems, each provincial system and each local market system include a plurality of government unit systems, each government unit system includes a plurality of sub-service systems, wherein the provincial system and the plurality of local market systems are the same in level, i.e., the data demand service system may be a government unit system or a sub-service system. The target business system may also be a government agency system or a sub-business system. Because the data demand service system and the target service system cannot directly communicate, the data demand service system and the target service system must communicate through the data exchange network module and/or the city sharing exchange module, if the data demand service system and the target service system are located in the same city level system, the communication between the data demand service system and the target service system only needs to be completed through the corresponding same city exchange node. It should be noted that the embodiment of the present application is illustrated in a provincial level, but is not limited to the provincial level, but may be a country level, a world level, or the like.
In the implementation mode, a P2P-based government data sharing exchange system aims at a flattened 'net' -shaped structure, breaks a tree-shaped cascade structure and strengthens domain division management. And point-to-point connection is realized in the network structure, so that the real-time sharing property of data is enhanced. The data exchange network module has several network transmission nodes, each node corresponds to the provincial level sharing exchange node and the different local cities sharing exchange node, and the nodes break the original administrative level system and the provincial level and the different local cities are level. The city sharing exchange node corresponds to different provincial systems and city systems, and the system comprises different unit systems and corresponds to different service systems. The data collected from the service system is configured and then mounted into the P2P file system on the network transmission node, so that the data storage is completed, and then the data transmission is carried out according to the request of each node, so that the data instantaneity is greatly improved.
Further, in one implementation, the target network transmission node includes: the device comprises a receiving unit, a target P2P file system and a result sending unit.
The receiving unit is used for receiving the government affair data acquisition request sent by the data demand service system and the target government affair data uploaded by the target service system based on the government affair data acquisition request. It can be understood that the data transmission management and control module forwards the government service data acquisition request sent by the data demand service system to the target network transmission node, the target network transmission node will determine the specific information of the government service data acquisition request, and send the government service data acquisition request to the target service system through the corresponding sharing exchange node, and the target service system will acquire the target service data and upload the target service data to the target network transmission node after receiving the request, thereby completing the acquisition of the target service data.
And the target P2P file system is used for processing the target government affair data to obtain a target configuration file corresponding to the target government affair data, wherein the target configuration file comprises a configuration data file with a first hash value and a configuration metafile with a second hash value.
And the result sending unit is used for sending a response message to the data transmission management and control module so that the data transmission management and control module informs the data demand network transmission node that the target configuration file is obtained.
It can be understood that the target service data is processed into the configuration data file and the configuration meta file, and the hash values corresponding to the configuration data file and the configuration meta file are encrypted, so that the risk of file theft is reduced. In addition, the first hash value and the second hash value are unique, that is, in the P2P-based system for sharing and exchanging government service data, a file can be determined by one hash value, so that the configuration data file can be uniquely addressed by using the first hash value at the destination network transmission node, and the configuration metafile can be uniquely addressed by using the second hash value.
In the implementation mode, the P2P file system based on the hash is designed, the data can be configured, mounted and transmitted, the consistency and traceability of the data at each node can be effectively guaranteed through the unique property of the hash value, and the problems of poor data consistency and difficult tracing are effectively solved.
Further, the target P2P file system may include: the system comprises a configuration data file generation unit and a configuration metafile generation unit, wherein the configuration data file generation unit is used for generating the configuration data file corresponding to the target government affair data and configuration information corresponding to the configuration data file, and storing the configuration information under a preset directory through a preset type interface, and the configuration information comprises a first hash value of the configuration data file, generation time of the configuration data file, a responsibility object of the configuration data file and effective time of the configuration data file; the configuration metadata file generation unit is used for generating the configuration metadata file corresponding to the target government affair data, the file name corresponding to the configuration metadata file and the second hash value based on the configuration data file and the configuration information corresponding to the configuration data file, which are obtained by the configuration data file generation unit, and storing the configuration metadata file and the file name corresponding to the configuration metadata file and the second hash value under a preset directory through the interface of the preset type, wherein the configuration metadata file indexes the configuration data file through the first hash value.
The interface of the preset type can be http-RPC.
It will be appreciated that as shown in fig. 4, the target configuration file is made up of two files, a configuration data file and a configuration metafile, respectively. The configuration data file is obtained after identifying and classifying the target service data, and the configuration data file can comprise the following configuration information: a first hash value (hash) of the configuration data file, a time of generation of the configuration data file, a liability object of the configuration data file, and a validation time of the configuration data file. The first hash value is a unique identifier of the configuration data file, the generation time refers to the generation time of the configuration data file, the responsibility object refers to an operator responsible for the configuration data file, and the effective time refers to the moment when the configuration data file is applied to the service system. The configuration metafile is obtained based on the configuration data file and the configuration information corresponding to the configuration data file, and with continued reference to fig. 4, the configuration metafile corresponds to the information file of the configuration data file, and the generation time, responsibility object, validation time and first hash value of the configuration data file are recorded. Meanwhile, the configuration information of the configuration metafile comprises: the configuration metafile name and the second hash value are also unique in the system, i.e. the configuration metafile name is unique in the system, a metafile name corresponding to a fixed hash value. The configuration metafile can be found from the target P2P file system by the metafile name (or the hash value corresponding to the metafile name) and the content of the configuration metafile can be read.
In this implementation, a directory index may be formed by configuring a metafile, and since the configuration metafile stores the generation time, the validation time, and the responsible person, the change history of the configuration may be traced, so that possible failure causes may be checked, and the metafile contains information of an operator, thereby locating the responsible object. The data demand P2P file system corresponding to the data demand network transmission node can read and analyze the configuration metafile with the fixed name, can obtain the configuration effective time and the first hash value of the configuration data file, reads the configuration data file from the data demand P2P file system at the time of generating the effect, and applies the configuration data to the service system.
In one implementation, the target network transmission node further includes: and the synchronization unit is used for synchronizing the target configuration file to other network transmission nodes. It will be appreciated that the P2P file system in each network transport node needs to ensure consistency of the configuration data of each node. The main purpose of synchronizing the target configuration file to each network transmission node is to ensure the data consistency and the integrity between the P2P file systems corresponding to different network transmission nodes, so that the coordination of data sharing and service flow can be realized. If the target configuration file is stored in only one P2P file system, other network transmission nodes cannot update and modify the data as required, which results in data out of sync and thus data errors and traffic confusion. By synchronizing the data target configuration file to each system, the data of different P2P file systems can be ensured to be consistent all the time, so that the possibility of data errors and conflicts can be reduced, and the data transmission efficiency can be improved, namely, when a business system corresponding to a certain network transmission node needs government service data corresponding to the target configuration file, the business system only needs to communicate with the network transmission node to obtain the government service data, and does not need to communicate with other network transmission nodes through a data transmission management and control module. In addition, the target configuration file has a unique hash value, and the hash value can be queried and confirmed by other network transmission nodes, so that the consistency of the same configuration file can be ensured easily among the network transmission nodes.
In one implementation, the target network transmission node further includes: and the verification result notification unit is used for notifying the data transmission management and control module whether the target government affair data supports the shared verification result. It can be understood that after receiving the government service data acquisition request, the data transmission management and control module queries the service system corresponding to each node, and broadcasts verification information to the target service system under the condition that the target service system is determined to store the target service data, wherein the verification information is used for indicating the target service system to verify whether the target service data supports sharing or not; and the target service system performs verification according to the verification information and sends the verification result to the target network transmission node, and a verification result notification unit of the target network transmission node notifies the verification result to the data transmission management and control module.
In this implementation, the target service data is checked first, and if the target service data includes sensitive information, a problem of data leakage may occur if the target service data is shared. Therefore, before sharing government data, the data needs to be inspected and verified to determine whether the data can be shared, so as to ensure the security, legitimacy and rationality of the sharing.
In one implementation, the data demand network transmission node includes a request sending unit, an obtaining unit, a data demand P2P file system, and a request responding unit.
And the request sending unit is used for sending the government affair data acquisition request sent by the data demand service system to the data transmission management and control module under the condition that the stored configuration file does not contain the file corresponding to the target government affair data. It can be understood that after receiving a government affair data acquisition request sent by a data demand service system, firstly querying whether a corresponding P2P file system stores a configuration file corresponding to the target government affair data, if so, directly analyzing the configuration file, and sending the target government affair data obtained by analysis to the data demand service system through a corresponding local exchange node; if the request is not stored, the request is required to be forwarded to the data transmission management and control module, and the data transmission management and control module performs scheduling.
The acquisition unit is used for acquiring the target configuration file sent by the target network transmission node through a preset type interface. The interface of the preset type can be an http-RPC, and the interface is consistent with the transmission node of the target network. It may be understood that, after determining the target configuration file, the target network transmission node sends a response message to the data transmission management and control module to notify the data transmission management and control module, and the transmission management and control module notifies the data demand network transmission node to acquire the target configuration file, because the target network transmission node uses a preset type of interface when storing the target configuration file, the data demand network transmission node needs to use the same interface to acquire.
And the data demand P2P file system is used for storing the configuration data file and analyzing the configuration data file to obtain the target government affair data. It can be understood that, when the obtaining unit obtains the target configuration file, the obtaining unit stores the target configuration file in a preset directory of the data requirement P2P file system, and notifies the configuration file analysis unit of a first hash value of the configuration data file or a second hash value of the configuration meta file corresponding to the target configuration file, the configuration file analysis unit searches the configuration data file according to the first hash value and analyzes the configuration data file to obtain the target service data, or searches the configuration meta file according to the second hash value and analyzes the configuration meta file to obtain the first hash value, searches the configuration data file according to the first hash value, and analyzes the configuration data file to obtain the target service data.
And the request response unit is used for sending the target government affair data to the data demand service system.
In the implementation mode, the communication of each service system only through the corresponding network transmission node is realized, the cascade structure in the traditional technology is broken, the data transmission time is saved, and the real-time performance of data sharing exchange is greatly improved.

It can be appreciated that the data transmission management and control module can implement network scheduling of government affair data based on the government affair data acquisition request.
By way of example, with continued reference to fig. 3, a specific embodiment of the present application will be described. Assuming that the local city a public security bureau needs data of the local city B market big data bureau, the local city a will send a data request to the corresponding shared switching node, and the data transmission management and control module searches the data at this time, finds that the B market big data bureau has the data needed by the local city a, and will tell the B market through message broadcasting at this time. The B market confirms that the data can be shared to the A market through verification, and the data transmission process is started at the moment. And uploading the data to the corresponding shared switching node for storage by the service system in the B market, informing the corresponding network transmission node, and taking the data out of the shared switching node and placing the data in the P2P file system after the network transmission node passes the verification. The P2P file system identifies and classifies the data, performs a series of configuration generation services, places the data in a corresponding file directory index, and configures a unique hash value for encryption so as to search for traceability sources. Then, the data transmission management and control module performs network scheduling on the configured data, and firstly transmits the data to a network transmission node corresponding to the data demand party, namely the A city, and the difference is that the data transmission is directly performed by the A city and the B city at the moment, and the data transmission is not performed by the provincial node, so that the data transmission time is greatly saved, and the real-time performance of data sharing and exchanging is improved. The network transmission node corresponding to the A market analyzes and stores the data in the P2P file system, then transmits the data to the corresponding sharing exchange node, and finally transmits the data to the specific demand department of the A market, thereby completing the point-to-point data transmission.
One specific embodiment of the P2P-based distributed government data sharing exchange described in the above fig. 2 to 4 is described below with reference to fig. 5. Specifically, this embodiment includes the steps of:
510: a configuration metafile name is determined. A configuration metafile name is determined for data collected from the business system.

530-540: the data collected from the service system can be sent to the P2P file system on the corresponding network transmission node, and the data synchronization among the nodes can be carried out according to the requirement.
550-555: the data is configured in a structured and serialized manner to form a configuration data file, a configuration data file hash is generated, the configuration data file can be uniquely addressed by using the hash value, and then the configuration data file is stored in a P2P file system and stored in a corresponding data file (directory index). After the P2P file system receives the configuration data file, the configuration data file is stored in the local node, and a hash value of the data file is generated.
560-565: the configuration generating program writes the hash value of the data file and the time of configuration validation into the corresponding configuration metafile, and then stores the configuration metafile in the P2P file system and saves the configuration metafile in the corresponding metafile (directory index). After the P2P file system receives the configuration metafile, the configuration metafile is stored in the local node, the hash value of the metafile is generated, and then the hash value of the metafile is associated with the designated metafile name.
570: the service program in the service system can regularly read the hash value of the configuration metafile from the distributed file system by using the configuration metafile name (or the hash value of the configuration metafile name) through an interface in an http-RPC mode, if the data is tampered, a new hash value can be generated, and the hash value at the moment is different from the previous hash value, so that the configuration metafile is changed.
580-590: the data demander can download the metafile from the corresponding network transmission node, analyze according to the unique hash value of the data file, and finally read the data and execute.
In the embodiment of the application, the distributed government affair data sharing and exchanging system based on P2P is adopted, and the method has the following beneficial effects:
1. the real-time performance of data exchange is enhanced. The data transmission is carried out among the nodes, so that only one node is required to write data, and any other node can read the data through the http RPC interface, so that a cascade structure in the traditional mode is eliminated, and the real-time performance of data exchange is effectively improved.
2. And ensuring the data integrity. The hash value in the P2P file system is unique, the integrity of the file can be ensured, and any damage to the file can generate new hash, so that the method has the characteristics of verifiability and discoverability.
3. Historical version of configuration data may be traced. The history change of the configuration data file is simply and clearly recorded in the configuration metafile, and the generation time and the effective time can trace back the history process. According to the historical information recorded by the metafile, a historical configuration data file can be found, and the information of an operator is recorded in the metafile to locate a responsible person.
4. Natural high availability. Each network transmission node is peer-to-peer, no primary and secondary division exists, one node is connected with a plurality of nodes, data can be backed up in each node, and the fault of any node can not influence a service system. The business program can read consistent and complete data from any other accessible node by only modifying the ip address.
5. Is easy to expand. When the system needs to add nodes, the system only needs to simply configure the nodes needing to be connected and start new nodes.
6. The operation and maintenance complexity is greatly reduced.
