Referring to fig. 1, fig. 1 is a timing chart of a method for generating a primary key in an intelligent contract according to an embodiment of the invention. The intelligent contract internal main key generation method in the embodiment of the invention can be applied to a server and a terminal. The terminal comprises, but is not limited to, electronic equipment with a communication function, such as a smart phone, a tablet personal computer, a notebook computer, a desktop computer and the like. The server may be an independent server or a server cluster formed by a plurality of servers. The server communicates with the terminal to receive a request sent by the terminal to generate an internal primary key, thereby generating at least one internal primary key.
In fig. 1, a terminal receives a request sent by a user to start generating a server internal main key, and sends the request for generating the server internal main key to a distributed main key generating system, wherein an interface of the distributed main key generating system is integrated in program software installed in the terminal, and when the program software runs, the distributed main key generating system can be called; the distributed main key generation system generates external main keys according to a request for generating the internal main keys of the server and sends the external main keys to the terminal; the terminal receives an external main key generated by the distributed main key generation system and sends the external main key and preset parameters required by generating the internal main key of the server to the server; the method comprises the steps that a server receives a request for generating an internal main key sent by a terminal, generates at least one internal main key according to a preset rule according to an external main key and preset parameters, and then sends related services identified by the internal main key to the terminal; and the terminal receives the related service identified by the internal main key and sent by the server and displays the service to the client for inquiring.
Referring to fig. 2, fig. 1 is a flowchart illustrating a method for generating a primary key in an intelligent contract according to an embodiment of the invention. The method is applied to the server. In specific implementation, the method for generating the primary key inside the intelligent contract is realized through software installed on the server. More specifically, the method for generating the primary key inside the intelligent contract is realized through the intelligent contract in the blockchain installed on the server. Thus, the generation of internal main keys in the intelligent contract is reduced, the generation of the internal main keys is excessively dependent on an external system, and the development cost and complexity are further reduced. As shown in FIG. 2, the method includes the following steps S1-S2.
S1, receiving a request for generating an internal main key sent by a distributed application, wherein the request for generating the internal main key comprises an external main key generated by a distributed main key generation system and preset parameters required by generating the internal main key.
In the embodiment of the invention, when a user operates a distributed application installed on a terminal to create a new service on a blockchain, the distributed application firstly sends a request for generating an external main key to a distributed main key generation system through an interface of the distributed main key generation system; the distributed internal main key generation system receives a request for generating an external main key sent by the distributed application, generates the external main key, and returns the generated main key to the distributed application; after the distributed application receives the external main key generated by the distributed main key generation system, a new service creation request is sent to the intelligent contract in the blockchain, wherein the new service request is a request for generating the internal main key of the intelligent contract and comprises the external main key and preset parameters. The preset parameters are other parameters needed by the intelligent contract to generate an internal main key. The external primary key is a primary key in the form of a character string generated by combining the current server system time, the own machine ID and the current count after the distributed primary key system receives a request sent by the distributed application. In this embodiment, the external primary key is a snowflake key, which is a character string in the form of a 13-bit integer.
It should be noted that, the interaction between the distributed application and the distributed primary key generating system, and the interaction between the distributed application and the smart contract are all implemented through HTTP or RPC (Remote Procedure Call Protocol ).
S2, generating at least one internal main key according to the external main key and the preset parameters and preset rules, and identifying different related services based on the at least one internal main key.
In the embodiment of the invention, the intelligent contract receives the external main key and preset parameters sent by the distributed application and generates a plurality of internal main keys for internal use of the intelligent contract according to preset rules.
In the implementation, because the intelligent contract can generate a plurality of internal main keys for the internal use of the intelligent contract according to one external main key generated by the distributed main key generation system, the generation of the internal main key in the intelligent contract can be reduced to excessively depend on the external system, so that the business logic in the intelligent contract can be decoupled from the external system, and the expandability of the contract is improved.
In one embodiment, referring to FIG. 3, step S2 above includes the following steps S21-S22.
S21, determining a name space array according to the preset parameters based on the preset data table.
In the embodiment of the invention, the preset data table is a data table in an intelligent contract. In particular embodiments, a service namespace mapping table records different service data. Based on the service name space mapping table and preset parameters, a name space array can be determined so as to ensure that the main keys in the intelligent contracts generated subsequently are different from each other, and the aim that different services are identified by different main keys is fulfilled.
S22, generating the internal main key according to the name space array and the external main key.
In the embodiment of the invention, after the name space array is determined according to the preset parameters based on the preset data table, the name space array and the external main keys are used as the input parameters to be input into the generator function in the intelligent contract to generate a plurality of internal main keys, so that the function of generating a plurality of internal main keys according to a single external main key is realized.
In one embodiment, referring to fig. 4, the above step S22 specifically includes the following steps S221-S223.
S221, splicing the name space array and the external primary key into a binary number array.
S222, calculating the binary number group through a preset algorithm to obtain binary numbers.
S223, carrying out preset coding on the binary number to obtain the internal primary key.
In the embodiment of the invention, after a name space array is determined according to preset parameters based on a preset data table, firstly, the name space data and an external primary key are spliced into a binary number array, then the binary number array is calculated through a preset algorithm to obtain binary numbers, and finally, preset encoding is carried out on the binary numbers to obtain the internal primary key.
In specific implementation, the binary number group is calculated by a salt hash algorithm to obtain a binary number, and then the binary number is Hex-coded to obtain an internal primary key.
Fig. 5 is a flowchart of a method for generating a primary key in an intelligent contract according to another embodiment of the present invention. As shown in fig. 5, the smart contract internal main key generation method of the present embodiment includes steps S41 to S46. Steps S41 to S42 are similar to steps S1 to S2 in the above embodiment, and will not be described here again. Steps S43 to S46 added in the present embodiment are described in detail below.
S43, storing the related service of the internal primary key identification into a blockchain.
S44, judging whether the related business is successfully stored in the block chain, if so, executing the step S45, otherwise, executing the step S46.
S45, the related service is sent to the distributed application.
S46, sending an unsuccessful prompt to the user.
In the embodiment of the invention, after an internal main key is generated according to an external main key and preset parameters and a preset rule, the intelligent bonding date stores related services identified by the main key into a blockchain, and if the related services are successfully stored in the blockchain, the related services are sent to a distributed application; if the related business is stored unsuccessfully in the blockchain, the related business can send an unsuccessfully prompt message to the distributed application so as to remind the user that the generation of the primary key in the intelligent contract is unsuccessful. For example, pop up an unsuccessful prompt.

More specifically, the method for generating the internal main key of the intelligent contract is realized through the distributed application installed on the terminal, so that the generation of the internal main key in the intelligent contract is reduced, the excessive dependence on an external system is relied on, and the development cost and complexity are further reduced. As shown in fig. 6, the method includes the following steps S51 to S55.
S51, receiving a request sent by a user for starting generation of an intelligent contract internal main key.
S52, sending a request for generating the intelligent contract internal main key to a distributed main key generation system.
