Detailed ways

In order to be able to understand the above objectives, features and advantages of the application more clearly, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other if there is no conflict.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terminology used in the specification of the application herein is only for the purpose of describing specific embodiments, and is not intended to limit the application.

Fig. 1 is a flowchart of a smart contract processing method according to the first embodiment of the present application. The smart contract processing method can be applied to an application scenario of a Fabric-based blockchain business platform. Among them, the application scenarios of the Fabric-based blockchain business platform include client, server and blockchain networks. The client is used to obtain different operation requests of the user, and send the operation request to the server in the service platform for processing; the server is in communication connection with the blockchain network; the blockchain network It is used to respond to the user's operation request and return the response result of the user's request to the client.

As shown in FIG. 1, an embodiment of the present application provides a smart contract processing method, which is applied to an http server of a blockchain node, and the smart contract processing method may include the following steps:

S11. Receive the http request sent by the client.

In at least one embodiment of the present application, the http request refers to a request message from the client to the server, and the http request may include a data query request, an operation and maintenance request, and the like.

S12. Parse the URI identifier in the http request.

In at least one embodiment of the present application, the http request includes a webpage identifier (URI, UniformResourceIdentifier, uniform resource identifier) in a preset format for indicating the address of the requested webpage in the blockchain smart contract. The webpage identifier is an expression of the location and access method of resources available on the Internet, and is the address of a standard resource on the Internet. Each resource file on the Internet has a unique URI.

Since all http requests need to be processed by the blockchain node through the http request proxy to the smart contract, the web page identifier in the preset format needs to indicate the information of the smart contract to be requested. The webpage identifier in the preset format is preset by system personnel. For example, the webpage identifier in the preset format may be: http://nodeip/smartcontractname and http://nodeip/smartcontractname/xxx. Among them, smartcontractname and smartcontractname/xxx are the indicated information of the smart contract to be requested.

When receiving the http request sent by the client, the http request is sent to the http server of the blockchain node, and the blockchain node can provide the web by providing the http server service to the blockchain node Service, so that the blockchain node can proxy the http request. It is understandable that the http server of the blockchain node is used to send the http request to the http server of the corresponding smart contract according to the URI information carried in the received http request; the http server of the blockchain node also uses To receive the http request response data sent by the http server of the smart contract, and output the http request response data to the client.

In at least one embodiment of the present application, the method further includes: building an http server on a blockchain node; obtaining the server address and port number of the http server; configuring the server in the blockchain node Address and the port number, and use the http server as a proxy server for the blockchain node.

Optionally, build an http server based on Node.js. Node.js is a lightweight Javascript runtime environment. Because Node.js uses an event-driven, non-blocking I/O model, it is lightweight and efficient.

The block chain node and the http server are placed in a network, and the server address and port number are configured in the block chain node. After the configuration is completed, the http server serves as the proxy server of the blockchain node. When the blockchain node sends a network request to the outside world, it must pass through the http server, and the http server will proxy the blockchain node to the outside world. Request and act on behalf of the blockchain node to receive the result returned by the outside world according to the network request. Therefore, the http server essentially acts as an intermediary for the blockchain node to communicate with the outside world.

In at least one embodiment of the present application, the step of parsing the URI identifier in the http request includes: obtaining a request message of the http request; parsing the request message to obtain the request of the http request Method, URI identification, domain name, file suffix name information.

S13. Convert the URI identification into a smart contract URI identification.

In at least one embodiment of the present application, the client can output requests from different users, and only requests from users with corresponding permissions can be responded to. Preferably, before the step of converting the URI identification into a smart contract URI identification, the method further includes: matching verification information corresponding to the URI identification, and the verification information includes a digital signature and user information. One or more of; the URI identification is verified according to the verification information; when the verification of the URI identification is passed, the URI identification is converted into a smart contract URI identification. Wherein, the digital signature is a digital signature performed by the client sending the http request on the URI identifier by using a preset digital signature algorithm, and the preset digital signature algorithm is an algorithm preset by a user.

It is understandable that when the verification information is a digital signature, the step of verifying the URI identifier according to the verification information includes: digitally signing the received URI identifier through a preset digital signature algorithm; The obtained digital signature is compared with the digital signature carried by the URI identification to determine whether the comparison result is consistent; if the judgment result is consistent, the URI identification passes the signature verification.

When the verification information is blacklist verification, the step of verifying the URI identifier according to the verification information includes: traversing a pre-stored user information blacklist database according to the user information carried in the URI identifier; and determining the Whether the user information carried by the URI identifier is a blacklist user; if the judgment result is no, the URI identifier passes the blacklist verification.

Preferably, a tag is added to the http request, and the tag is used to record the verification information verification process of the http request and the corresponding relationship between the http request and the http server-side interface of the smart contract.

In at least one embodiment of the present application, the step of converting the URI identification into a smart contract URI identification includes: obtaining a keyword at a preset position in the URI identification; matching from a smart contract keyword library Generate the target smart contract corresponding to the keyword; obtain the target URI identifier of the target smart contract; use the target URI identifier as the URI identifier of the target smart contract.

Specifically, since the format of the URI identification is preset by system personnel, the preset location is a location that indicates the smart contract information to be requested. For example, if the format of the URI identification is http://nodeip/smartcontractname, the keyword at the corresponding preset location is smartcontractname.

Exemplarily, suppose that there is a smart contract for querying the list of old laity in the smart contract keyword library, and the corresponding keyword is oldlaicontract. The URI identifier obtained by parsing the http request through the http server of the blockchain node is: http://nodeip/oldlaicontract/, the keyword in the URI identifier: oldlaicontract is obtained, and the smart contract is traversed according to this keyword The keyword library matches the smart contract corresponding to this keyword, which is called the target smart contract oldlaicontract, so as to determine the URI identification of the target smart contract. The URI identification of the smart contract is: http://127.0.0.1: 398213/.

S14. Send the http request to the http server of the smart contract corresponding to the smart contract URI identification.

In at least one embodiment of the present application, the smart contract (smartcontract) runs in a sandbox environment and can only communicate with the blockchain node. The http request is sent to the http server of the smart contract identified by the smart contract URI through the http server of the blockchain node. The smart contract runs in the blockchain network, and the smart contract is redesigned to provide http server services for the smart contract, so that the smart contract can support web standard services, and the user can access the smart contract arbitrarily through the client The custom page of the contract.

Specifically, the method for providing http server services to the smart contract includes: building an http server on the smart contract; obtaining the server address and port number of the http server that has been built; configuring the server address in the smart contract And the port number, and use the http server as a proxy server for the smart contract. Since the method of providing http server service to the smart contract has the same principle as the method of providing http server service to the blockchain node, it will not be repeated here.

S15. Receive smart contract data sent by the http server of the smart contract and obtained by parsing the http request.

In at least one embodiment of the present application, the http server of the blockchain node receives smart contract data sent by the http server of the smart contract and obtained by parsing the http request. Preferably, before the http server of the smart contract parses the http request to obtain smart contract data, the method further includes: receiving an http request sent by the http server of the blockchain node, where the http request carries Characteristic information; according to the characteristic information query ranking strategy, the ranking priority corresponding to the characteristic information is obtained; and the processing order of the http request is adjusted according to the ranking priority.

Specifically, the sorting strategy is used to record the correspondence between characteristic information and sorting priority, and the characteristic information includes one or any combination of the following: user identification, data type, device type information, device IP address, and page jump information . Determine the sorting priority of the data acquisition request according to the characteristic information carried in the data acquisition request, and adjust the processing order of the data acquisition request according to the sorting priority. In this way, the processing sequence of the data acquisition request can be made more reasonable, and the waiting of some users can be effectively shortened. The data response time optimizes the allocation of internal resources of the system and effectively improves the user experience.

In at least one embodiment of the present application, when the http server of the smart contract parses the http request to obtain smart contract data, it includes the following steps: parsing the http request through the http server of the smart contract, and according to the analysis result Determine the function interface of the smart contract to be called; call the smart contract on the blockchain to process the business according to the function interface of the smart contract to be called; obtain the smart contract data generated for the business process.

Specifically, the data and logic of the smart contract are separated, that is, the smart contract includes a data contract and a behavior contract. Among them, the data contract specifically stores data, which only performs simple data acquisition and modification; the behavior contract specifically describes the background business processing logic. Each smart contract implies a contract address and a compiled ABI (Application Binary Interface), which is encapsulated and hidden by node.js, and only provides a unified function interface to the outside. Through the ABI, the encapsulated js package code is used to determine the function interface of the smart contract to be called according to the analysis result.
