Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a service call auditing method based on a blockchain, including:
s101, deploying a blockchain platform based on the blockchain framework.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform is first deployed based on the blockchain framework. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
In the process of deploying the blockchain platform, a service calling end (hereinafter referred to as a calling end) and a service called end (hereinafter referred to as a called end) may be deployed in the blockchain platform as nodes, which is not described herein again.
S102, obtaining a service calling record of a called end, wherein the service calling record comprises at least one of calling time, calling end information and called end information.
When a developer carries out software-related research and development on a program, a system or a platform, if all functions are executed by the developer, the workload of the developer is too large, and the program is too complex, and at the moment, the workload of the developer can be reduced through service calling. When service calling is performed, the called data resource of the called end provides service for the external calling end in an Application Programming Interface (API) mode, and then charges the owner of the calling end according to the number of times the Interface is called. The calling end may be in the form of a program, a system, a client, a server, and the like, which is not limited herein.
When the service is called, corresponding service calling records are generated, and the service calling records become the basis for the payment of both parties. The service calling record comprises at least one of calling end information, called end information and calling time. The information of the calling end and the information of the called end may include, for example, an Internet Protocol (IP) address, a service port, a service protocol, a protocol format, a protocol type, etc., which are not described herein again.
S103, hashing the obtained service calling records respectively to obtain a plurality of first hash values.
And S104, splicing the first hash values to generate a character string, hashing the character string to obtain a second hash value, and writing the second hash value into the block chain platform.
When only one service call record is available, the service call record can be directly written into the blockchain platform, so that the two parties can pay the fee through the record on the blockchain platform. However, in general, the number of service call records is large and large. At this time, if all records are directly written into the blockchain platform, the data volume in the blockchain platform is too large, and an excessive space is occupied. It also causes inconvenience when both parties refer to the record.
Therefore, the obtained service call records can be respectively hashed to obtain a plurality of first hash values. The first hash value is obtained by hashing the service call record, so that the storage space occupied by the record can be greatly reduced. However, since the number of service invocation records is large, the number of the first hash values is also large, so that the space occupied by the whole system is still large.
At this time, the obtained multiple first hash values may be concatenated to generate a character string, and then the character string is hashed to obtain a second hash value, and then the second hash value is written into the block chain platform. When the first letter of the next second hash value is spliced, the first letter of the next second hash value can be spliced behind the last letter of the previous first hash value, and the splicing is finished by analogy. When the first hash values are spliced, the first hash values can be spliced according to calling time, so that corresponding hash calculation is performed when problems occur in later periods of the two parties. The service calling record is hashed, and the hash is performed once after splicing, so that the space occupied by the data in the block chain platform can be greatly reduced. And because the data in the blockchain platform is public and transparent, the calling end and the called end can inquire the served calling record through corresponding ways at any time. And because the blockchain platform is in distributed storage, data tampering of a single node cannot be effective, and the truthfulness and the credibility of the data on the blockchain platform are ensured. Once two parties generate inconsistent opinions about the times of service call records, because one service call record is tampered, the hash values of layers are damaged, and the final second hash value is inconsistent with the real second hash value. The two parties can perform the steps in the service call auditing method through the service call records provided by the two parties for layer-by-layer hash, and the two parties compare with each other according to the second hash value stored in the block chain platform, and the consistent party is the correct party, so that the occurrence probability of divergence is reduced, and the benefits of the two parties are maintained.
In an embodiment, when the obtained service call records are hashed, the service call records obtained every preset time period may be hashed respectively. For example, every ten minutes, service records acquired within the ten minutes are hashed. In general, the data volume of the service call record acquired within ten minutes is already large, and the data volume can be stored.
Of course, when the number of the obtained service invocation records reaches the preset number, the hash may be performed on the preset number of the service invocation records. For example, every hundred service call records are obtained, the one hundred service call records may be hashed separately. Of course, if the number of service call records obtained in the preset time period, for example, ten minutes, has not yet reached one hundred, the service call records obtained in the time period may be respectively hashed to prevent the problem that the records cannot be written into the blockchain platform in time.
In one embodiment, the charges corresponding to the service call records may also be obtained and written into the blockchain platform. The cost of the service call records can be obtained at one time, and can also be obtained by obtaining the cost of each service call record and calculating. By writing the fee into the blockchain platform, the two parties can pay more conveniently.
In one embodiment, the corresponding intelligent contracts may also be generated in advance and deployed in the blockchain platform. The intelligent contract comprises a service calling record, a Hash algorithm and a splicing algorithm. The intelligent contract is used for enabling the received service calling records to respectively pass through a Hash algorithm to obtain a plurality of first Hash values, splicing the first Hash values through a splicing algorithm to generate a character string, enabling the character string to pass through the Hash algorithm to obtain a second Hash value, and writing the second Hash value into the block chain platform. Since the intelligent contracts on the blockchain platform are public, each node can check whether the intelligent contracts are in accordance with the preset agreement or not and deploy the intelligent contracts on the own node. And both parties can also inquire the intelligent contract through corresponding ways, so that the degree of automation of the transaction is improved, and meanwhile, the trust degree of both parties is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
As shown in fig. 2, an embodiment of the present application further provides a service invocation auditing apparatus based on a blockchain, including:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein,
the memory stores instructions executable by the at least one processor to enable the at least one processor to:

and splicing the first hash values to generate a character string, hashing the character string to obtain a second hash value, and writing the second hash value into the block chain platform.
